Abstract/OtherAbstract:
The synthesis of several novel substituted (Z)-2-amino-5-(1-benzyl-1H-indol-3-yl)methylene-1-methyl-1H-imidazol-4(5H)-ones structurally related to aplysinopsin have been carried out under microwave irradiation and conventional heating methods. The analogs 3a, 3b, 3d-3g,3k and 3l were evaluated for their in vitro cytotoxic activity against an NCI 60 human tumor cell line panel. Compound 3f exhibited good growth inhibitory properties against all but four of the human cancer cell lines examined, and afforded LC(50) values <10microM for 30% of the cell lines in the panel. Compound 3e was an effective inhibitor of leukemia, CNS, melanoma, and breast cancer cell growth, but generally less effective as a cytotoxic agent. Thus, the aplysinopsin analog 3f was regarded as a useful lead compound for further structural optimization.
