The synthesis of trifluoromethyl (Tfm) analogs of known nanomolar matrix metalloproteinases (MMPs) inhibitors has been performed. The synthetic protocol is based on a moderately stereoselective aldol reaction of trifluoropyruvate with an N-acyl-oxazolidin-2-thione for the construction of the core α-Tfm-malic unit. Both the diastereomeric forms of the target α-Tfm-malic hydroxamates showed micromolar
已进行了已知的纳摩尔基质金属蛋白酶(MMPs)抑制剂的三氟甲基(Tfm)类似物的合成。合成规程基于三氟丙酮酸与N-酰基-恶唑烷丁-2-硫酮的中等立体选择性醛醇缩合反应,用于构建核心α-Tfm-苹果酸单元。根据酶谱测试,目标α-Tfm-苹果酸异羟肟酸酯的两种非对映体形式均表现出对MMP-2和9的微摩尔抑制潜能,相对于母体未氟化化合物而言,显着下降。我们还报告了一些分子建模结果,为实验结果提供了理论依据。
