Regioselective Cu(I)-catalyzed 1,3-dipolar cycloaddition of steroidal 17alpha-azides with different terminal alkynes afforded novel 1,4-disubstituted triazolyl derivatives in good yields in both the estrone and the androstane series. The antiproliferative activities of the structurally related triazoles were determined in vitro on three malignant human cell lines (HeLa, MCF7 and A431), with the microculture
区域选择性的铜(I)催化甾体17α-叠氮化物与不同的末端炔烃的1,3-偶极环加成反应在雌酮和雄甾烷系列中均以良好的收率提供了新型1,4-二取代的三唑基衍生物。通过微培养四唑法在体外在三种恶性人类细胞系(HeLa,MCF7和A431)上确定了结构相关三唑的抗增殖活性。
