A. Nishikawa et al., DESIGN AND SYNTHESIS OF CURACIN-A ANALOGS WITH VARIED SIDE-CHAIN STRUCTURES, Bioorganic & medicinal chemistry letters, 7(20), 1997, pp. 2657-2660
A series of side chain-modified analogs of curacin A, a powerful antim
itotic agent isolated from a Caribbean cyanobacterium was synthesized
and the effect of these compounds on in vitro microtubule polymerizati
on was examined. The analogs showed weak or no anti-tubulin activity,
suggesting that the whole side chain structure of curacin A is require
d for the interaction with tubulin. (C) 1997 Elsevier Science Ltd.
