Compound 5 possesses an unusual formyl ester substituent at the C-1 position. The structures of the novel compounds were established on the basis of spectroscopic methods. Compounds 1-5 were found to be very potent cytotoxic substances when evaluated against a panel of human cancer cell lines.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyChemistryPharmacology, Toxicology and PharmaceuticsNovel cytotoxic 1H-cyclopenta[b]benzofuran lignans from Aglaia ellipticaArticleSCOPUS10.1016/S0040-4020(97)10231-9
