Structure–activity relationship study at the 3′-N-position of paclitaxel: synthesis and biological evaluation of 3′-N-acyl-paclitaxel analogues

Add time:07/14/2019    Source:sciencedirect.com

A series of 3′-N-acyl-paclitaxel analogues 1a–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 β-substituted conjugated double and triple bond to N-carbonyl generally resulted in increase of cytotoxicities.
