Abstract
This current study presents the phytochemical analysis of Croton velutinus, describing phenylpropanoids obtained from this species. The fractionation of the roots hexane extract led to the isolation of four new phenylpropanoids derivatives, velutines A-D (1-4) and three known (5-7). Their structures were established based on spectroscopic (1D-2D NMR; HRMS and IR) analysis. Cytotoxic, trypanocidal and anti-inflammatory activities of compounds 1-7 were evaluated. Only compounds 2 and 5 showed cytotoxic activity against cancer cell lines (B16F10, HL-60, HCT116, MCF-7 and HepG2), with IC50 values ranging from 6.8 to 18.3 μM and 11.1 to 18.3 μM, respectively. Compounds 2 and 5 also showed trypanocidal activity against bloodstream trypomastigotes with EC50 values of 9.0 and 9.58 μM, respectively. Finally, the anti-inflammatory potential of these compounds was evaluated on cultures of activated macrophages. All compounds exhibited concentration-dependent suppressive activity on the production of nitrite and IL-1β by macrophages stimulated with LPS and IFN-γ. These results indicate phenylpropanoids esters (2 and 5) from C. velutinus as promising cytotoxic, trypanocidal and anti-inflammatory candidates that warrants further studies.
