Dakin-West reaction, hydrolysis, condensation with thiocyanate derivatives, alkylation with 2-iodoacetamide and ethyl chloroacetate, and coupling with 4-pyridylmethyl chloride, ethoxymethyl chloride and benzyloxymethyl chloride. All the synthesized compounds were screened for their activity against HIV-1 (wild type) and some of them (especially Capravirine like structures) were found active.
己内酰胺(AG-1549)或S-1153的不同类似物是通过合成2-(5-苄基-4-异丙基-1-甲基-2,3-二氢-1H-咪唑-2-基硫基)乙酰胺(3a)制备的-c),[5-苄基-1-(乙氧基甲基)-4-乙基-1H-咪唑-2-基硫基]乙酸乙酯(10),2- [5-烷基-4-取代的1-(吡啶-4-酰基甲基)-1H-咪唑-2-基硫基]乙酰胺(12a-f)和2- [5-苄基-1-(苄氧基甲基)-4-异丙基-1H-咪唑-2-基硫基]乙酰胺(14a-1)从它们相应的氨基酸开始,通过一系列反应:Dakin-West反应,水解,与硫氰酸酯衍生物的缩合,与2-碘乙酰胺和氯乙酸乙酯的烷基化,以及与4-吡啶基甲基氯,乙氧基甲基氯和苄氧基甲基氯的偶合。筛选了所有合成的化合物对HIV-1(野生型)的活性,发现其中一些(特别是Capravirine样结构)具有活性。
