An analogue of Tipranavir was designed by replacing the dihydropyrone core with a 1,3-cyclohexanedione ring. The thio-alkyl group was used as a temporary protection group for α, β-unsaturated cyclohexane-1,3-diketone derivative, and the resulting compound was reacted with an ethyl-organometallic reagent to form the desired Michael addition product. By using this strategy, a more stable analogue of Tipranavir was synthesized and exhibited excellent HIV protease inhibition (12 nM Ki).
通过将Tipranavir的二氢吡喃酮核心替换为1,3-环己二酮环,设计了一种Tipranavir类似物。使用硫代烷基作为α,β-不饱和环己烷-1,3-二酮衍生物的临时保护基团,所得化合物与乙基有机金属试剂反应,形成了所需的Michael加成产物。利用这一策略,合成了一种更稳定的Tipranavir类似物,并表现出优异的HIV蛋白酶抑制活性(Ki值为12 nM)。
