A new series of compounds, in which the 2-amino-4-methoxyphenyl ring of phenstatin analogue 5 was replaced with 2- or 3-amino-benzoheterocycles, was synthesized and evaluated for antiproliferative activity and inhibition of colchicine binding. The lack of activity of 3 ',4 '-dimethoxy- and 4 '-methoxy-benzoyl derivatives (8 and 9, respectively) indicates that the 3 ',4 ',5 '-trimethoxybenzoyl moiety is critical for the activity. Two compounds, 7 and 11, displayed potent antiproliferative activity, with IC50 values ranging from 25 to 100 nM against a variety of cancer cell lines. Derivative 11 was more active than CA-4 as an inhibitor of tubulin polymerization. The results demonstrated that the antiproliferative activity was correlated with inhibition of tubulin polymerization. (c) 2005 Elsevier Ltd. All rights reserved.
