Six neolignans including three previously undescribed metabolites: 1-[(7R)-hydroxy-8-propenyl]-3-[3'-methoxy-1'-(8'-propenyl)-phenoxy]-4,5-dimethoxybenzene, 4-hydroxy-5-methoxy-3-[3'-methoxy-1'-(8'-propenyl)phenoxy]-1-(7-oxo-8-propenyl)benzene and
BACKGROUND
Malignant melanoma is one of the most aggressive skin cancer and chemotherapeutic agents currently in use are still unsatisfactory. Prevention and early diagnosis are the only effective tools against this tumour whose incidence and mortality rates are highly increased during the last
In this work was evaluated the cytotoxic activity of dehydrodieugenol B (1) and methyldehydrodieugenol B (2) isolated from Nectandra leucantha (Lauraceae) through cytokinesis-block micronucleus (CBMN) and Comet assay. Compounds 1 and 2 displayed in vitro toxicity against human melanoma cells
Dehydrodieugenol B and five related natural neolignans were isolated from the Brazilian plant species Nectandra leucantha. Three of these compounds were shown to be active against murine (B16F10) and human (A2058) melanoma cells but non-toxic to human fibroblasts (T75). These results stimulated the
