Astacin metalloproteinases, in particular meprins α and β, as well as ovastacin, are emerging drug targets. Drug‐discovery efforts have led to the development of the first potent and selective inhibitors in the last few years. However, the most recent compounds are based on a highly flexible tertiary amine scaffold that could cause metabolic liabilities or decreased potency due to the entropic penalty
虾红素金属蛋白酶,特别是 meprins α 和 β,以及 ovastacin,是新兴的药物靶点。过去几年,药物发现工作导致了第一个有效的选择性抑制剂的开发。然而,最新的化合物基于高度灵活的叔胺支架,由于与靶标结合时的熵损失,可能会导致代谢负担或效力降低。因此,本研究的目的是发现新型构象约束支架,作为进一步抑制剂优化的起点。从柔性叔胺到刚性杂芳族核心的转变导致了抑制活性的增强。此外,与最近报道的抑制剂相比,一些化合物已经对单个虾红素蛋白酶表现出更高的活性,并且还具有良好的脱靶选择性特征,因此使它们成为非常适合用于靶标验证的化学探针。
