A group of steroidal derived acids were synthesized and found to be human Cdc25A inhibitors. Their potency ranged from 1.1 to > 100 microM; the best ones compare very favorably with that of the novel cyano-containing 5,6-seco-cholesteryl acid 1 (IC50=2.2microM) reported by us recently (Peng, H.; Zalkow, L. H.; Abraham, R. T.; Powis, G. J. Med. Chem. 1998, 41, 4677). Structure-activity relationships
合成了一组类固醇衍生酸,发现它们是人Cdc25A抑制剂。它们的效力范围从1.1到> 100 microM。最好的是与我们最近报道的新型含氰基的含氰基的5,6-seco-胆固醇1(IC50 = 2.2microM)相比非常有利的(Peng,H .; Zalkow,LH; Abraham,RT; Powis,GJ Med.Chem.1998,41,4677)。这些化合物的构效关系表明,疏水性胆固醇侧链和游离羧基对活性至关重要。这两个药效基团之间的距离对于这些化合物的效力也很重要。几种化合物在NCI体外癌细胞系中显示出选择性的生长抑制作用。
