cells lines (GI(50) of 340-850 nM) could be retained when the heterocyclic substituent possesses H-bond acceptor properties. A good correlation between the calculated electron density of the heterocyclic ring and anti-proliferative activity was observed. Docking of the most active compounds into their putative site of action, the colchicine binding site of tubulin, suggests that they bind through a

The synthesis and antiproliferative activity of analogues of estradiol 3,17-O,O-bis-sulfamates (E2bisMATEs) are discussed. Modifications of the C-17 substituent reveal that an H-bond acceptor is essential for high antiproliferative activity. The local environment in which this H-bond acceptor lies can be varied to an extent. The C-17-oxygen linker can be deleted or substituted with an electronically
