Aman Tedasen, Araya Khoka, Siribhorn Madla, Somchai Sriwiriyajan, Potchanapond Graidist
January 2020, 16(68):28-38
Background: Black pepper (Piper nigrum L.) is widely used as a traditional medicine, including usage for pain relief, fevers, as well as an anticancer agent. Previously, we reported that piperine-free P. nigrum extract (PFPE) inhibited breast cancer in vitro and in vivo. Objective: In this present study, we explored the anticancer effects of PFPE on cholangiocarcinoma (CCA). Materials and Methods: 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to analyze cytotoxic potential of PFPE whereas deoxyribonucleic acid (DNA) fragmentation followed by Western blot analysis were used. Results: PFPE composed of alkaloid, flavonoid, amide, lignans, opioid, and steroid. This crude extract represented cytotoxic effect against CCA cells which stronger than dichloromethane P. nigrum crude extract and piperine, especially on KKU-M213 (median inhibition concentration [IC50] at 13.70 μg/ml) and TFK-1 (IC50at 15.30 μg/ml). Interestingly, PFPE showed lower cytotoxicity against normal human cholangiocyte MMNK-1 cells (IC50at 19.65 μg/ml) than KKU-M213 and TFK-1 cells. Then, the molecular mechanisms of PFPE were firstly evaluated by DNA fragmentation followed by Western blot analysis. The degradation of DNA was observed on KKU-M213 and TFK-1 cells after treatment with PFPE at day 2. Then, proliferation proteins including topoisomerase II, AKT8 virus oncogene cellular homolog, avian myelocytomatosis virus oncogene cellular homolog, cyclin D1, signal transducer and activator of transcription 3, cyclooxygenase-2, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were decreased and p21 was increased. Furthermore, apoptotic proteins, such as tumor protein p53, Bcl-2-associated X protein, and p53 upregulated modulator of apoptosis were upregulated. Meanwhile, antiapoptotic protein B-cell lymphoma 2 was down-regulated. Conclusion: These results indicated that PFPE inhibited CCA through the down-regulation of cell proliferation and induction of apoptosis pathway.

January 2020, 16(68):81-86
Background: Hylocereus undatus produces fruits known as dragon fruit (Pitaya). The fruit and other parts of Hylocereus species are used for the treatment of diuretic, gastritis, kidney problems, and wound healing. Objectives: To investigate anti-inflammatory properties of the flesh and peel of Pitaya and to identify the major bioactive constituent(s). Materials and Methods: The flesh and the peel of the fruit were blended separately with water, vacuum-distilled, freeze-dried, and then used for the bioassay tests against the 5-Lipoxygenase (5-Lipox), Cyclooxygenase-2 (COX-2), and Acetylcholinesterase (AChE) enzymes. Results: Squalene appeared to be the dominant constituent (13.2%) in the flesh of the fruit. The crude flesh extract and the squalene showed strong activities against AChE with inhibition percentage >80% (IC50 <43 μg/mL). The peel was active against 5-Lipox with inhibition of 81%. Inhibition percentages recorded for the positive controls used were 77% for Zileuton against 5-Lipox (IC5028 μg/mL), 85% for the Galantamine against AChE (IC50 16 μg/mL), and 86% for the Celecoxib against COX-2 (IC5032 μg/mL). For maximum efficacy against the three enzymes, squalene showed the best performance with EC50values ranging between 46 and 47 μg/mL. Conclusion: The findings showed that Pitaya has a significant potential for the management of inflammatory conditions through different mechanisms including, leukotriene, prostaglandins, and cholinergic pathways. To the best of our knowledge, identification of squalene in the dragon fruit flesh and the validated biological activities were not reported previously and therefore accounted for the novelty of the study.

January 2020, 16(68):199-205
As of today, the utilization of herbal medicines has taken up the pace in treating diseases. This is due to the fact that they have lower risk of adverse reactions. Numerous plants are being used traditionally to treat various dreadful diseases including diabetes. Piper longum is one of the major and important medicinal plants in various systems of medicine, including the Ayurvedic system of medicine. Among the major bioactive compounds found in this plant, few compounds, viz., piperine, piperlongumine, piperlonguminine, and retrofractamide A, have been selected for studying the effectiveness on antidiabetic activity. An in silico approach was utilized to observe the major phytochemical properties and interaction studies of the constituents of P. longum, and finally, a pharmacophore investigation was carried out. In this study, we have observed the interaction of the four bioactive compounds taken from P. longum with the receptors via molecular docking technique. The binding of the ligands firmly with the receptors confirmed the fact that piperine, piperlongumine, piperlonguminine, and retrofractamide A act as inhibitors for dipeptidyl peptidase-4, GKRP, 11β-hydroxysteroid dehydrogenase type 1, glutamine-fructose-6-phosphate transaminase 1, and protein tyrosine phosphatase 1B, which encourage the glucose digestion and increment insulin affectability. The information acquired from this investigation might be taken further for in vitro examinations, which may, in the long run, be useful in recognizable proof of novel and successful particles. The outcomes acquired from this examination might provide strong understanding in the utility of phytochemicals against diabetes.

Tien-Lin Chang, Shang-Fang Wu, Der-Yuan Wang, Chih-Hung Huang
January 2020, 16(68):8-12
Background: Placentas are widely used in the production of cosmetics, Chinese medicines, and injections. As the esthetic medicine market grows, challenges such as impure preparations and an increasing number of counterfeit products develop, owing to the lack of standard inspection methods and accurate description of the composition of these products. Objectives: To develop a universal species identification method for placental products. Materials and Methods: Fresh swine, cattle, goat, and frozen human placenta were used as references, while Placenta Hominis and placental extract products from the market as trial samples. Samples were prepared by kit-free DNA isolation, and vertebrate-specific primer sets of mitochondrial 16S and 12S rRNA were used for species-specific region amplification. Direct sequence of amplicons and National Center for Biotechnology Information database comparison was carried for species identification of the testing samples. Results: Trail tests had confirmed the usability of this method. Six of seven Placenta Hominis samples were shown to contain human DNA traces, while the seventh showed no DNA signals belonging to any mammals and a paper-like material underneath the vegetal part, instead of membrane-like placental tissue by visual inspection, suggesting the possibility of counterfeit. Eight injectable and cosmetic placental extract products were tested, and none of them contained analyzable DNA or comparable protein fragments except one, which DNA was from rainbow trout (Oncorhynchus mykiss) rather than sheep, as per the product claim, and was hence misbranded as per the U.S. Food and Drug Administration definition. Conclusion: Our species identification method is easy-to-operate, unified, and resource-saving, which can be applied to different placental products.

January 2020, 16(68):174-180
Background: Renal calculi, a painful kidney stone disease has worldwide health hazard. Cucurbita pepo is used for the management of lower urinary tract disease, benign prostatic hyperplasia, and micturition difficulty. Objective: The present study was investigated to resolve the antiurolithic potential of methanol extract of C. pepo (MECP) seed against sodium oxalate-induced renal calculi using both in vitro and in vivo models. Materials and Methods: MECP was prepared by macerating C. pepo seed powder in methanol. Gas chromatography coupled with mass spectrometry (GC-MS) analysis was performed to characterize the phytochemical profile of MECP. In vitro techniques such as nucleation, aggregation, growth, and dissolution assays were performed using different concentrations (20, 40, 60, and 80 mg/mL) of MECP and the standard drug cystone to determine their calcium oxalate (CaOx) crystals inhibitory potential. In male albino rats, calculi were induced by intraperitoneal administration of sodium oxalate (70 mg/kg) for 10 days. Various doses (250, 500, and 1000 mg/kg) of MECP were administered orally to male albino rats. Various pathological parameters such as body and kidney weights, serum (creatinine, blood urea nitrogen, and uric acid), urinary (calcium, potassium, oxalate, sodium, magnesium, phosphate, pH, and volume) analysis, and kidney histopathology were executed. Results: GC-MS fingerprints showed that beta-tocopherol, stigmasterol, and squalene are the major phytochemicals found in MECP. Results demonstrated that MECP significantly inhibited various steps of CaOx crystal formation such as nucleation, aggregation, growth, and dissolution in dose-dependent manner. MECP normalized the raised levels of oxalate, calcium, sodium, phosphate, uric acid, restored alterations in histopathology while elevated the reduced levels of magnesium, urine volume, and pH. Conclusion: The undertaken study rationalized the usage of C. pepo as an alternative or adjuvant treatment for renal calculi after clinical trials in human subjects.

Context: Tinospora cordifolia (Willd.) Miers is an antidiabetic herb globally marketed as a single or polyherbal formulation. The pharmacological activities of T. cordifolia suggest its potential to be co-administered with commonly prescribed oral hypoglycemic drugs in the therapeutic management of diabetes mellitus. Aims: The aim of this study was to evaluate the potential pharmacokinetic (PK) and pharmacodynamic (PD) interactions of the aqueous extract of T. cordifolia (TCE) with metformin (MET), sitagliptin (SITA), and glibenclamide (GLI) in streptozotocin (STZ)-induced diabetes in rats. Settings and Design: The aqueous TCE (400 mg/kg, p.o.) was co-administered with MET (90 mg/kg, p. o.), SITA (10 mg/kg, p. o.), and GLI (1 mg/kg, p. o.) for 28 days in STZ-induced diabetes in rats. Materials and Methods: The PK parameters of the three drugs were calculated using Phoenix WinNonlin®, and PD activity was determined by estimating fasting blood glucose, liver and kidney function tests, and lipid parameters. Further, histopathological examination of pancreatic cells and estimation of pancreatic antioxidant enzymes was carried out. Statistical Analysis Used: The pharmacokinetic parameters were estimated using pharmacokinetic program WinNonlin® version 3.0 (Pharmasight corporation, Mountain view, CA). The pharmacodynamic parameters were analysed using Graph Pad prism Version 6.00 applying one-way ANOVA followed by the Tukey–Kramer post test. Results: No significant PK interaction was observed between TCE and the three oral hypoglycemics. However, a significant improvement was observed in glycemic control and the conditions associated with diabetes mellitus. In addition, no incidences of hypoglycemia were observed. Conclusion: The co-administration of TCE with MET, SITA, and GLI helped in better management of diabetes and associated comorbidities than their individual administrations. There were no significant PK interactions observed. Our findings provide insights into the safety and efficacy of the combination therapy of TCE with MET, SITA, and GLI in the management of diabetes and associated conditions.

Pian Wang, Yan Wang, Qingbin Zhang, Hongbo Zhang, Zheng Li, Xiaoying Liu, Lavleen Kaur, Manish Kumar
January 2020, 16(68):133-141
Background: Vascular dementia (VaD) is an age-associated highly prevalent brain disorder characterized by progressive cognitive insufficiency. Nutritional deprivation-associated rise in homocysteine (HCy), dyslipidemia, endothelial debility, and redox imbalance is a key facet of VaD. Spirulina platensis (spirulina) is a high-nutritional-value cyanobacterium appreciated by modern as well as diverse civilizations of antiquity (e.g., Mexican-Aztec, African-Kanambous). The present study aims to investigate the therapeutic effects of spirulina (S. platensis) in VaD. Materials and Methods: L-methionine (1.7 g/kg) was given orally to simulate VaD in rats. Spirulina was administered (0.5, 1, and 2 g/kg; p.o.) for 4 weeks daily. The neurobehavioral assessments and biochemical analysis in the whole brain (thiobarbituric acid-reactive substances [TBARS], glutathione [GSH], and acetylcholinesterase [AChE]) and serum (cholesterol, HCy, and nitrite) of rats were conducted. Results: Cognitive impairment in rats by L-methionine was attributable to statistically significant (P < 0.05) elevation in HCy, cholesterol levels, oxidative stress, AChE activity, and a decline of endothelial-derived nitric oxide. Spirulina attenuated (P < 0.05) the L-methionine-triggered cognitive insufficiency in rats. TBARS levels and AChE activity were reduced and GSH content was increased by spirulina in the brain of L-methionine-treated rats. Spirulina-attenuated L-methionine triggered increase in blood HCy and total cholesterol levels in rats. In aortic-ring tests, acetylcholine-induced endothelium-dependent relaxation was abolished by L-methionine, which showed endothelial mutilation and was potently attenuated by chronic treatment with spirulina. Conclusion: In L-methionine model of VaD, therapeutic intervention by spirulina (S. platensis) imparts appreciable relief in cognitive deficits.

Background: Heliotropium europaeum L. is known to contain pyrrolizidine alkaloids and possesses a wide variety of biological activities. Objective: The objective of the study was to discover antioxidant phytochemical compounds in H. europaeum and assess their in vitro lipoxygenase (LOX)- and angiotensin-converting enzyme (ACE) inhibitory activities. Materials and Methods: H. europaeum herbs were extracted exhaustively by maceration using 90% aqueous ethanol. Solvent fractionation with n-hexane, dichloromethane (CH2Cl2), ethyl acetate (EtOAc), and n-butanol was performed with the dried extract until complete exhaustion. Two antioxidant active fractions (CH2Cl2and EtOAc) were combined and subjected to medium pressure liquid chromatography followed by reversed-phase high-performance liquid chromatography. Quantitative evaluation in terms of the antioxidant activities of the isolated compounds was performed using the 2,2-diphenyl-1-picrylhydrazyl assay. The potential limiting effects on the action of ACE and soybean LOX were assessed quantitatively. Results: Isolates of eight newly identified phenolic compounds from H. europaeum exhibited antioxidant and ACE- and LOX-inhibitory activities. The isolated compounds were identified as kaempferol (1), luteolin (2), quercetin (3), kaempferol-3-O-glucoside (4), and luteolin-7-O-glucoside (5), in addition to caffeic acid (6), rosmarinic acid (7), and methyl rosmarinate (8). Among the isolated compounds, quercetin possessed the most potent antioxidant activity (IC50= 8.1 μM) and ACE-inhibitory activity (IC50= 17.5 μM), whereas rosmarinic acid and its methyl ester showed the strongest LOX-inhibitory activity (IC50s = 4.2 μM and 3.6 μM, respectively). Conclusion: Our study is the first report on the phenolic constituents of the H. europaeum herbal extract and their biological activities. A total of eight phenolics were identified in this extract and isolated for the first time. Our results on H. europaeum extract constituents provide some scientific evidence on the beneficial effects of its traditional uses.

January 2020, 16(68):99-107
Background: Prodigiosin is a bioactive bacterial pigment produced by Serratia marcescens and possesses anticancer, antibiotic, antifungal, antibacterial, and immunosuppressive activities without any toxic effects on human cells. Objectives: The study was planned to optimize the effect of ultravoilet (UV) light and acridine orange (AO), as mutagens and incubation time on prodigiosin production by S. marcescens in nutrient agar broth and peptone glycerol broth. Materials and Methods: The optimization was done by constructuing a quadratic polynomial response surface model using a bifactorial central composite design. The S. marcescens starian was treated with UV light (0, 30, 60, 90, and 120 s) and various concentrations of AO (0, 50, 100, 150, and 200 μg/mL) and incubated in the selected growth media for different times (0, 15, 30, 45, and 60 h). The prodigiosin production was measured in terms of change in pH and optical density (OD) of the ethanolic extracts of culture media. Results: The prodigiosin production was found to be a significant linear and quadratic function of incubation time in both of the culture media. However, a statistically non-significant increased prodigiosin production, in terms of pH and OD of the extracts, was observed under the influence of both mutagens. The optimum values of incubation time to achieve optimal production of prodigiosin from UV light-exposed and AO-treated cultures were found to be in the range of 37–60 h, respectively. Conclusion: The pigment production was increased significantly with an increase in the incubation time. The study provides the optimum conditions for the production of prodigiosin in research and commercial field.

Background: During smoking cessation, nicotine withdrawal is associated with many symptoms including cognitive impairment and depressed mood, which lower the desire to quit smoking and predicts smoking relapse. Thus, pharmacotherapies that improve cognitive functions during nicotine withdrawal would be paramount in developing efficacious smoking cessation agents. Medicinal plants are currently considered as a promising source to identify new therapeutics. The roots of Anacyclus pyrethrum are used in traditional medicine to treat various diseases. Objectives: The aim of this study was to evaluate the behavioral effects of ethanolic extract of A. pyrethrum (EEAP) on smoking withdrawal in a rat model. Subjects and Methods: EEAP was administered orally at a dose of 200, 400, and 800 mg/kg. Forced swimming test (FST), open-field, marble-burying, and plus-maze tests were used to measure the level of depression and anxiety in animals. In addition, the novel object recognition test was used to test memory impairment. Results: The results showed that EEAP-treated animals had decreased immobility time in forced swimming test and they buried fewer marbles. The percentage of the time spent and the number of entries in the open arm within the elevated plus-maze test was increased in smoking withdrawn rat after treatment. On the other hand, EEAP increased the recognition of memory in the novel object recognition task. Conclusion: Taken together, our data indicated potential antidepressant-like and anxiolytic-like effects of EEAP in rats and the improvement of memory. Besides, this plant does not have any acute or subchronic toxicity effect.

Background: Among its many uses, Acmella oleracea (L.) R. K. Jansen as an anthelmintic agent for general intestinal helminthiasis is remarkable because of its indigenous usage in the Mizo traditional medicine. However, the rationale has not been established. Objectives: The objective of this study is to perform chemical analysis of the plant extract using gas chromatography-mass spectrometry (GC-MS) and to test the anthelmintic activity on intestinal helminths. Materials and Methods: Methanol extract of the whole plant was prepared and volatile compounds were analyzed using GC-MS. Anthelmintic activity was studied by survival test on the cestode Raillietina echinobothrida and the nematode Ascaridia galli. Anthelmintic effects were examined using scanning electron microscopy. Results: Thirteen compounds were detected, with methyl n-hexadecanoate (palmitic acid) as the major constituents. N-Alkylamides such as N-isobutyl-(2E,4Z,8Z,10E)-dodecatetraenamide and N-(2-phenylethyl) non-2(E)-en-6, 8-diynamide were present. The plant extract was significantly effective (P < 0.05) at all concentrations tested on both the parasites and showed dose-dependent activity similar to that of albendazole. On the cestode, tegumental shrinkage, erosion of microtriches, and destruction of suckers with clumping of the spines were observed. The nematode was also extensively deformed with its lips collapsed, warty surface on the head, and contracted cuticle on the main body. Conclusion: A. oleracea contains bioactive compounds that have broad-spectrum activity on cestode and nematode parasites.

Background: Cinnamomum osmophloeum (Co), a member of the Lauraceae, is an indigenous medicinal crop in Taiwan, and it contains higher cinnamaldehyde in essential oil than do other Cinnamomum species. Among these species, Cinnamomum burmannii (Cb) is frequently adulterated as Co because of their similar morphological characteristics or features. Objective: The purpose of this study was to develop a DNA-based molecular method for rapid authentication of the indigenous Co and prevention of its adulteration. Materials and Methods: The internal transcribed spacer (ITS) regions of nuclear ribosomal DNA from various Cinnamomum species were amplified by polymerase chain reaction (PCR), and these obtained sequences were used for sequence analysis. Based on the sequence variants among various Cinnamomum species, restriction fragment length polymorphism (RFLP) was used to differentiate these Cinnamomum plants. Results: Two restriction endonucleases, MylI and EcoRV, were specifically used to digest the PCR-amplified ITS DNA from seven Cinnamomum species. The PCR-RFLP results demonstrated that the different restriction patterns that were produced by these two restriction enzymes clearly distinguished Co from Cb and five other Cinnamomum species simultaneously. Conclusion: The PCR-RFLP analysis developed in this study provides an alternative method for rapidly identifying Cinnamomum plants at the species level using DNA polymorphisms.

January 2020, 16(68):93-98
Background: Despite the widespread ethnopharmacological use and significance of Silybum marianum (SM) seeds, most of its phytochemical and biological properties are still yet to be confirmed using validated scientific methods. Objectives: The current study was designed to investigate the phytochemical and biological properties of SM seed extract. Materials and Methods: Methanolic extract of SM (MESM) dried seeds was fractionated by column chromatography, and fractions (SA1–SA10) were evaluated for antioxidant, antimicrobial, and cytotoxic activities (brine shrimp lethality assay and antileishmanial assay). Results: All fractions showed considerable level of antioxidant potential. Free radical scavenging activity of fraction (SA9) was maximum at 80.7%. Fraction SA4 exhibited substantial total antioxidant capacity (101.81 μg/mg). In ferric-based reducing antioxidant power assay, fraction SA4 showed the highest antioxidant power (258.93 μg/mg). Phytochemical screening of the fractions (SA1–SA10) inferred that total phenolic contents were maximum in fraction SA7 (85.13 μg/mg) and total flavonoid contents were found to be highest in fraction SA1 (58.24 μgQE/mg). However, mild antibacterial and antifungal activities were shown by different fractions. To evaluate cytotoxic potential, brine shrimp lethality bioassay was performed. Among all the fractions, the fraction SA9 revealed the lowest LD50of 49.99 μg/mL, whereas all the other fractions tested demonstrated significant cytotoxic property. The results of antileishmanial assay showed that the fraction SA6 possesses the highest mortality percent (84%) compared to the other fractions. Conclusion: These findings revealed that MESM can be an important source of natural antileishmanial herb that can be used as a therapeutic alternative for leishmaniasis.

Ashraf A Hassan, Yahya Hasan Hobani, Neji Mosbah, Saif Elden Abdalla, Mohammad Zaino, Syam Mohan, Maged El-Setouhy
January 2020, 16(68):168-173
Background: Khat chewing is culturally endemic in the Southern areas of Saudi Arabia. Many health-related issues such as the incidence of carcinogenicity and comorbidities associated with the chewing of khat have been reported earlier. Objectives: Mainly, the objective of the study was to assess the risk of genotoxicity caused due to oxidative stress that may result from khat chewing among chronic chewers from Jazan Province of Saudi Arabia. Materials and Methods: Hundred and twenty-two adult males were recruited after signing informed consent. Ninety participants were chronic khat chewers (CKCs), while the control group consisted of 32 non-chewers of matched age and gender for the study group. A blood sample was collected from all participants and kept at 4°C until the time of assay. The activity of superoxide dismutase (SOD) and glutathione reductase (GR) were estimated in erythrocyte lysate as well as 8-hydroxydeoxyguanosine (8-OHdG) level in plasma. Results: There is a decreased SOD activity, which might be due to an increase in the endogenous production of reactive oxygen species resulted from the increase in lipid hydroperoxides. Furthermore, the significant elevation in GR activity was observed, reflecting the presence of highly toxic compounds. The 8-OHdG levels were higher in khat chewers group in comparison to the control, but this increase was statistically insignificant. Conclusion: CKCs will be at considerable risk of oxidative stress as a result of a significant reduction in antioxidant enzymes. This would be a good reason for them to quit chewing khat for health benefits.

Background: Murraya koenigii leaves are traditionally used in India and other South Asian countries as a spice in regular food dishes to improve taste and aroma. These leaves are known for the rich content of mahanimbine, a key carbazole alkaloid. Although there are numerous reports that support the neuroprotective role of various alkaloids, the effect of mahanimbine against memory impairment remains to be elucidated. Objective: The present study aimed to explore the neuroprotective potential of mahanimbine against lipopolysaccharides (LPS)-induced memory deficit in Institute of Cancer Research (ICR) mice. Materials and Methods: Group of mice were being fed with mahanimbine (1, 2, and 5 mg/kg, p. o.) for 30 days. Subsequently, neuroinflammation was induced with LPS (250 μg/kg, i. p.) for 4 days. Morris water maze (MWM) assessment was conducted to assess spatial memory. The brain was then collected and subjected to amyloid-beta (Aβ) (Aβ1-42and Aβ1-40) measurement, acetylcholine (ACh) and acetylcholinesterase (AChE) assays and neuroinflammatory analyses (interleukin [IL]-1 β, tumor necrosis factor alpha [TNF-α], IL-10 transforming growth factor beta [TGF-β], and cyclooxygenase [COX]). Results: The MWM test showed that treatment with mahanimbine significantly enhanced memory of LPS-challenged mice by decreasing both escape latency as well as escape distance. Pretreatment of the LPS-challenged mice with mahanimbine improved central cholinergic transmission by increasing ACh level through inhibition of AChE. It also significantly attenuated Aβ1-40level. While anti-inflammatory cytokines (TGF-β and IL-10) were upregulated, mahanimbine significantly inhibited pro-inflammatory cytokines (IL-1 β and TNF-α), the total activity of COX, and expression of COX-2 gene in LPS-induced group. Conclusion: The overall findings supported the neuroprotective potential of mahanimbine against LPS-induced neuroinflammation.

Snehal Suryavanshi, Kavita Shinde, Prerna Raina, Ruchika Kaul-Ghanekar
January 2020, 16(68):181-186
Background: HC9, a polyherbal formulation, is based on Stanyashodhana Kashaya (an Ayurvedic formulation) that is being prescribed by Ayurvedic physicians for the treatment of various disorders of mammary glands. We have recently reported anticancer activity of HC9 in breast cancer cell lines through various molecular mechanisms. Few studies have shown an association between breast cancer and melanoma that has prompted us to find whether HC9 could regulate the melanoma growth as well. Aim of the Study: The aim was to investigate the tumor retardation and immunomodulatory potential of HC9 in mouse melanoma model. Materials and Methods: C57BL/6 mice, with B16F10-induced melanoma tumors, were divided into six groups: tumor control, doxorubicin (2 mg/kg body weight [b.w.]), low dose (100 mg/kg b.w.), intermediate (200 mg/kg b.w.), and high dose (400 mg/kg b.w.) of HC9. No tumor control served as the negative control group. The mice were orally gavaged with HC9 daily for 3 weeks. The urine and blood samples from all the animals were taken before necropsy. The expression of T-helper type 1 (Th1) (interferon-γ and interleukin [IL]-2) and Th2 (IL-4 and IL-10) serum cytokines was evaluated by ELISA assay. Results: HC9 significantly retarded the tumor growth in C57BL/6 mouse melanoma model. The animals did not show any changes in body weight and food consumption throughout the study period. Urine and histopathological analysis revealed no signs of toxicity in HC9-treated animals. HC9 appreciably increased the serum levels of Th1 with a concomitant decrease in Th2 cytokines. Conclusion: HC9 retarded the tumor growth in mouse melanoma model and induced immunomodulation, thereby suggesting the potential of the formulation against melanomas.
