ABSTRACT
Three new bisindole alkaloids, 3'-(2-oxopropyl)-19,20-dihydrotabernamine (1 ), 3'-(2-oxopropyl)-ervahanine B (2 ), 19,20-dihydrovobparicine (3 ), and 20 known compounds were isolated from the aerial parts of Tabernaemontana bufalina. The structures of these alkaloids were elucidated using spectroscopic methods. The absolute configurations of 1 -3 were determined by the circular dichroic exciton chirality method. Compounds 1 -23 were screened for their cytotoxicity against two human cancer cell lines, A-549 and MCF-7. Ten compounds (1 -3, 10, 14, 16, 17, 19, 22 , and 23 ) exhibited inhibitory effects against the two human cancer cells with IC50 values of 1.19 ~ 6.13 µM.
