   Introduction Top


The increasing incidence of adverse side effects associated with conventional drugs, and the emergence of resistance to antibiotics [1],[2] justifies the search for new drugs from vegetable species in order to combat the multiresistant microorganisms. [3],[4] The study of natural products from vegetable origin presenting antimicrobial activity has been shown in many perspectives mainly because of the presence of tannins, alkaloids, saponins, and terpenes. This illustrates the importance of natural products as sources of new antimicrobials agents. [5]

Cajanus cajan (L.) Millsp (Fabaceae) is a annual perennial shrub largely cultivated in tropical and subtropical regions of the world, typical to dry climates. [6] Its seeds are sources of vitamins, minerals, and proteins, [7] and it is popularly known as gaundú, ervilha de pombo among others. [8] Although there are few studies regarding the phytochemical profile of the roots in comparison with ones about C. cajan seeds, these different parts of the plant are used in traditional medicine as sedative and to treat cough, hepatitis, and diabetes. [9],[10]

This work is aimed to perform the phytochemical prospection and to evaluate the antifungal activity of ethanolic extracts from C. cajan fresh leaves and roots. Moreover, the possible modulator effect of fluconazole and ketoconazole was also analyzed.


   Materials and Methods Top


material obtention

C.cajan leaves and roots were collected from Gaviγo farma, Missγo Velha municipality (Ceatα States, Brazil) in April 2010. A voucher specimen was sent to the Herbarium Caririense Dαrdano de Andrade Lima, which is deposited on the registration #5108.

Preparation of extracts and phytochemical prospection

Fresh triturated leaves (700 g) and roots (862 g) were exhaustively extracted with cold ethanol for 72 h. [11] After this, the solvent was distilled in a rota evaporator under reduced pressure to give 200 g (leaves extract) and 180 g (roots extract). Phytochemical tests to detect the presence of secondary metabolites were performed following the method described by Matos. [12] These tests were based on the visual observation of color modification or precipitate formation after the addition of specific reagents.

Antifungal activity evaluation - minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC)

The minimal inhibitory concentration (MIC) was obtained by a broth microdilution assay according to NCCLS guidelines. [13] Before the tests, fungi were activated in Sabouraud medium (48 h, 35±2ºC). Three ATCC standard strains provided by Oswaldo Cruz Foundation - FIOCRUZ were used: Candida albicans ATCC40006, Candida krusei ATCC 6538, and Candida tropicalis ATCC 40042.

After the subculture, Each culture was mixed with a sufficient volume of sterile supplemented Sabouraud broth to achieve a turbidity equivalent to that of McFarland's no. 0.5 standard. To obtain the test inoculum, this suspension was further diluted with the same culture medium to approximately 1 × 10 6 colony-forming units (CFU)/mL immediately before use. Each dilution measuring 100 μL were distributed in 96-well plates plus extracts in different concentrations, achieving 5×10 5 UFC/mL as the final concentration of the inoculum.

Extracts and fractions were dissolved in distilled water and dimethyl sulfoxide (DMSO) to concentration of 1024 μg/mL. Further serial dilutions were performed by addition of the broth to reach a final concentration in the range of 512 a 8 μg/mL. All experiments were performed in triplicate, and the microdilution trays were incubated at 35±2 o C for 24 h.

The plates containing the fungal strains were analyzed and the turbidity of the broth as the indication of growth of microorganisms. [14] MIC was defined as the minimal concentration able to inhibit the yeast growth in comparison to positive control. The fungal culture that did not present growth was used to inoculate plates containing solid medium in dextrose potato agar (PDA) in order to obtain the minimal fungicidal concentration (MFC). [15],[16]

Fluconazole and ketoconazole modifying activity

The evaluation of ethanolic extracts as antifungal activity modifiers was performed using fluconazole and ketoconazole MICs obtained in the presence and absence of the microdilution method modified according to CLSI/NCCLS M7-A6 guideline. [13] Inhibitory concentration (MIC 1/8, 10% Sabouraud broth) were used against all strains previously described. Fungi were exposed to extracts that presented MICs ≤ 512 μg/mL.

The antifungal solutions (1024 μg/mL) were prepared in distillated water for use on the same day. A total of 100 μL of the antifungal solution, using serial dilutions (1 : 2), was added to the wells containing 10% sabouraud and the diluted fungal suspension (1 : 10). Final antifungal concentrations were 512, 256, 128, 64, 32, 16, 8, 4, 2, and 1 μg/mL. Microplates were incubated for 24 h at room temperature and the modulatory activity was determined by visualization of turbidity.


   Results and Discussion Top


prospection

Phytochemical prospection of C. cajan leaves and roots ethanolic extract indicated the presence of tannins, flavonoids and alkaloids. These results are in concordance with other studies performed with C. cajan leaves extracts too, where these same secondary metabolites classes were found. [17],[18] Other reports quantified and isolated flavonoids in leaves extract (quercetin, luteolin, apigenin, and isorhamnetin) [19],[20] and roots of this specie. [21],[10]

Biological activities are described for different secondary metabolites classis. Although the antifungal propriety of flavonoids is well known, flavonoids also possess antibacterial, antilipoperoxidative and antiparasitic activities. [22],[23] Tannins are reported to exhibit bactericidal and fungicidal properties [24] and alkaloids are antitumor, antiinflammatory and antimicrogial. [25]

Evaluation of antifungal activity (MIC) and minimal fungicidal conncentration (MFC)

As shown in [Table 1], the ethanolic extracts obtained from C. cajan inhibited the growth of yeasts strains. The leaves extracts presented a MIC of 256 μg/mL against C. albicans and C. tropicallis.

Leaves and seeds from C. cajan have been extensively studied because of the ethnopharmacological properties. Diverse activities have been elucidated as the anticandidal. In the study performed by Runyoro et al. [26] using the methanolic extract of leaves, a moderate activity against C. albicans was verified by the bioautography method. However, according to Bolle et al. [27] this method may be not accurate because it can induce the compound decomposition.

Ethanolic extracts from C. cajan leaves were very active against C. albicans[28] using the cavity and disk diffusion methods. This result corroborates our findings that can be considered clinically relevant [29] as the extract presented MIC ≤ 1000 μg/mL against all strains tested.

When Braga et al. [17] tested methanolic extracts of leaves and seeds were tested against C. albicans e Cryptococcus neoformans, the inhibition halos were considered to be very active, but a MIC value of 2500 μg/mL was obtained against C. albicans. A value much higher than that one found here. This can be explained by extracts of this species in different regions of Brazil can lead to extracts with different chemical composition from that previously reported.

The extracts studied here presented MFC ≥ 1024 μg/mL against all Candida species suggesting that the extracts can be fungistatic too.

Evaluation of fluoconazole and ketoconazole modifying activity

The modifier effect of fluoconazole and ketoconazole activity are shown in [Table 2]. It is possible to see a strong synergism between both antifungal and C.cajan extracts (MIC 1/8) against Candida species.

According to studies performed by Giordani et al, [30] essential oil from Thymus vulgaris and Origanum vulgare were strongly active against Candida albicans. Besides this, the essential oil from T. vulgaris potentialized the action of amphotericin B leading to the complete inhibition of fungal growth.

[Table 2] shows that both antifungal had their activity potentialized by leaves extracts against C. albicans. Roots extract, in combination with the fluoconazole and ketoconazole, presented better effects against the other Candida species. This is the first report of a natural product potentializing the fluoconazole and ketoconazole effects.


   Conclusion Top


The phytochemical prospection of C.cajan leaves and roots extracts have demonstrated the presence of diverse class of compound and these compounds are related to known biological activities (as antifungal). The leaves extract presented best activity against C. albicans and C. tropicalis.However, the evaluation of antifungal modifying activity suggest that the extracts studied here demonstrated to be a new therapeutic source to treat diseases associated to the yeasts resistant to conventional antifungal. The results are promising and they can stimulate future researches regarding the phytochemical, toxicological, and pharmacological aspects of natural products from Cajanus cajan.
