Irreversible covalent inhibitors can have a beneficial pharmacokinetic/pharmacodynamics profile but are still often avoided due to the risk of indiscriminate covalent reactivity and the resulting adverse effects. To overcome this potential liability, we introduced an alkyne moiety as a latent electrophile into small molecule inhibitors of cathepsin K (CatK). Alkyne-based inhibitors do not show indiscriminate
不可逆共价抑制剂可能具有有益的药代动力学/药效学特征,但由于存在不加区别的共价反应性和由此产生的不良反应的风险,仍然经常被避免使用。为了克服这种潜在的缺点,我们将炔部分作为潜在的亲电子试剂引入组织蛋白酶 K (CatK) 的小分子抑制剂中。晶体结构分析证实,基于炔烃的抑制剂不表现出任意的硫醇反应性,但通过与催化半胱氨酸残基形成不可逆共价键,有效抑制 CatK 蛋白酶活性。共价键形成速率 (kinact) 与炔部分的亲电性不相关,表明接近驱动的反应性。CatK 介导的骨吸收抑制作用已在人类破骨细胞中得到验证。总之,这项工作说明了炔烃作为小分子抑制剂中潜在亲电子试剂的潜力,从而能够开发具有改进安全性的不可逆共价抑制剂。
