Introduction of an amido group or an amino moiety into the alkenyl linker chain of cosalane (1) provided a newseries of analogues 3-8. The new compounds were evaluated as inhibitors of the cytopathic effect of HIV-1 and HIV-2 in cell culture. The replacement of the 1' and 2' carbons in the linker chain of I by an amido group was generally tolerated. The length of the linker chain and the stereochemistry
将氨基或氨基部分引入到al草烷(1)的烯基连接链中提供了一系列新的类似物3-8。新化合物被评估为在细胞培养物中抑制HIV-1和HIV-2的细胞病变作用。通常容许I的连接链中的1'和2'碳被酰胺基取代。连接链的长度和甾族环C-3处取代基的立体化学对抗病毒活性和效价都有重要影响。将氨基部分结合到接头中完全消除了抗HIV活性。在HIV复制周期中有几个步骤被提议作为治疗剂开发的目标(De Clercq,EJ Med。Chem。1995,38,2491; De Clercq,E.Pure Appl.Chem。1998,70, 567)。然而,当前批准的抗HIV药物仅针对病毒酶逆转录酶或蛋白酶(Carpenter。CCJ; MA菲斯切尔; SM汉默; Hirsch女士; DM雅各布森; DA; Katzenstein; JSG Montaner; DD里奇曼;密苏里州萨格(Saag);密歇根州Scho
