title: Design, synthesis and antiproliferative activity of tripentones: a new series of antitubulin agents.
abstract: Structure-activity relationship studies of a new series of tripentones (thieno[2,3-b]pyrrolizin-8-ones), led us to prepare several derivatives with antiproliferative activities. The most promising 3-(3-hydroxy-4-methoxyphenyl)thieno[2,3-b]pyrrolizin-8-one 20 (leukemia L1210, IC(50)=15 nM) was shown to be a potent inhibitor of tubulin polymerization.
