Antitumoral, Antioxidant And Antimicrobial Molecules From Combretum Rupicola

Abstract

This investigation describes the anticancer, antioxidant and antimicrobial properties of the extracts of Combretum rupicola, a native plant from Northeast of Brazil. Methanolic, ethyl acetate and chloroform extracts from leaves of C. rupicola were evaluated in relation to their potential in inhibiting the cell growth and cytotoxic properties against nine human cancer cell lines (MCF-7, NCI-ADR/RES, OVCAR-3, PC-3, HT-29, NCIH460, 786-O, UACC-62, K-562). In addition, antioxidant activity of these extracts was measured using DPPH as radical scavenging assay and the antimicrobial activities against nine pathogens were tested by agar diffusion method. Preliminary results showed that the this plant demonstrates to have moderate activity against bacteria but, on the other side, the extracts showed significant anticancer activitiesagainst four cell lines and the most significant activity was observed against MCF-7 (65.9 μg mL-1), highest inhibitory concentration IC50 0.22 μg mL-1 for antioxidant activity. These founds are the first scientific reports on secondary metabolites with biological activities of C. rupicola, suggesting the potential of this botanic species for pharmaceutical industry.41B422B428Butler, M.S., The role of natural product chemistry in drug Discovery (2004) J of Nat Prod, 67 (12), pp. 2141-2153Ripa, F.A., Nahar, L., Haque, M., Islam, M.M., Antibacterial, Cytotoxic and Antioxidant Activity of Crude Extract of Marsilea Quadrifolia (2009) Eur J of Scien Res, 33 (1), pp. 123-129Santos, S.N., Oliveira, L.K.X., Melo, I.S., Velozo, E.S., Roque, M.R.A., Antifungal activity of bacterial strains from the rhizosphere of Stachytarpheta crassifólia (2011) Afri J of Biot, 10 (25), pp. 4996-5000Pettit, G.R., Singh, S.B., Niven, M.L., Hamel, E., Schmidt, J.M., Isolation, Structure, and Synthesis of Combretastatins A-1 and B- 1, Potent New Inhibitors of Microtubule Assembly, Derived from Combretum caffrum (1987) J of Nat Prod, 50 (1), pp. 119-131Tan, F.X., Shi, S.H., Zhong, Y., Gong, X., Wang, Y.G., Phylogenetic relationships of Combretoideae (Combretaceae) inferred from plastid, nuclear gene and spacer sequences (2002) J of Plant Res, 115, pp. 475-481Fyhrquist, P., Mwasumbi, L., Haeggstrom, C.A., Vuorela, H., Hiltunen, R., Vuorela, P., Microscopic diagnosis of tumors of the central nervous system by phase contrast microscopy (2002) J of Ethnoph, 79, pp. 169-177McGaw, L.J., Rabe, T., Sparg, S.G., Jager, A.K., Eloff, J.N., Van Staden, J., An investigation on the biological activity of Combretum species (2001) J of Ethnoph, 75, pp. 45-50Ridley, H.N., Notes on the Botany of Fernando Noronha (1890) Botany, 27 (181), pp. 1-95Eloff, J.N., Katerere, D.R., McGaw, L.J., The biological activity and chemistry of the southern African Combretaceae (2008) J of Ethnoph, 119, pp. 686-699Grammer, A., Antibiotic sensitivity and Assay test (1976) Collins CH and Lyne PM, Eds.
