摘要:
Phenylcyclohexenes (PCHs) [e.g., trans-4-nitro-5-(2,3,4-trimethoxyphenyl) cyclohexene, 2d] were found to bind weakly to the colchicine site of bovine tubulin, but are the first mimics of colchicine found to have high activity towards plant cells. Structure-activity relationships for PCHs and biphenyl AC-ring analogues of colchicine (e.g., 2,3,4,4'-tetramethoxy-2'-methyl-1,1'-biphenyl, 3e) are discussed. (C) 2001 Elsevier Science Ltd.
