Achieving Dipeptidyl Peptidase 8 and 9 (DPP8/9) selectivity is a current challenge in chemical biology. Supported by activity-based protein profiling and X-ray crystallography, we disclose 4-oxo-β-lactams as potent, non-substrate-like nanomolar DPP8/9 inhibitors with different binding modes for DPP8/9, including an unprecedented targeting of an extended S2′ subsite in DPP8 and the best selectivity
实现二肽基肽酶 8 和 9 (DPP8/9) 选择性是化学生物学当前面临的挑战。在基于活性的蛋白质分析和 X 射线晶体学的支持下,我们公开了 4-氧代-β-内酰胺作为有效的、非底物样纳摩尔 DPP8/9 抑制剂,对 DPP8/9 具有不同的结合模式,包括前所未有的靶向扩展了 DPP8 中的 S2' 子位点和迄今为止报告的最佳选择性指数。
