A series of 3'-N-acyl-paclitaxel analogues la-v were synthesized and their cytotoxicities in vitro against several human tumor cell lines examined. It has been shown that distinct correlation between activity and N-acyl-substituent. The appropriate size of N-acyl group was indispensable for cytotoxicity, and moreover, the presence of beta-substituted conjugated double and triple bond to N-carbonyl generally resulted in increase of cytotoxicities.

A series of novel pyrrolocarbazoles was synthesized as potential PARP-1 inhibitors. Pyrrolocarbazole 1 was identified as a potent PARP-I inhibitor (IC50 = 36 nM) from our internal database. Synthesis of analogs around this template with the aid of modeling studies led to the identification of the truncated imide 14. Compound 14 (IC50 = 40 nM), with deleted B-ring, was found to be an equipotent PARP-1 inhibitor. (c) 2005 Elsevier Ltd. All rights reserved.
