Synthesis and cytotoxicity evaluation of (tetrahydro-β-carboline)-1,3,5-triazine hybrids as anticancer agents
摘要:
A series of tetrahydro-beta-carbolines and 1,3,5-triazine hybrids have been synthesized and evaluated for their cytotoxicity against a panel of eight human cancer cell lines and normal human fibroblasts (NIH3T3). It led us to discovery of racemic compounds 69, 71 and 75, which are selectively cytotoxic towards KB (oral cancer) cell line with IC(50) values of 1058, 664 7 and 122.2 nM, respectively, while their enantiopure forms are less active and not selective. Enantiopure compound 42 showed 2 5 times more selectivity towards MCF7 cells over normal fibroblast NIH3T3 cells with an IC(50) value of 740 nM, also arrests cell cycle in G(1) phase and induces apoptosis in MCF7 and MDA MB231cell lines.
