Novel deazaxanthine-based DPP-4 inhibitors have been identified that are potent (IC50 <10 nM) and highly selective versus other dipeptidyl peptidases. Their synthesis and SAR are reported, along with initial efforts to improve the PK profile through decoration of the deazaxanthine core. Optimisation of compound 3a resulted in the identification of compound (S)-4i, which displayed an improved in vitro
与其他二肽基肽酶相比,已经发现了新型的基于脱氮杂黄嘌呤的DPP-4抑制剂有效(IC 50 <10 nM)并且具有高度选择性。报道了它们的合成和SAR,以及通过修饰地氮杂黄嘌呤核心来改善PK谱的初步努力。化合物3a的优化导致鉴定了化合物(S)-4i,该化合物显示出改进的体外和ADME谱。通过从脱氮杂黄嘌呤改变为脱氮杂黄嘌呤模板,最终以化合物12g达到更高的PK谱,该化合物在大鼠中表现出良好的离体DPP-4抑制作用和更好的PK谱,提示每天一次在人体内给药。
