The structure-based design, synthesis, and biological evaluation of a new pyrazole series of irreversible KAT II inhibitors are described herein. The modification of the inhibitor scaffold of 1 and 2 from a dihydroquinolinone core to a tetrahydropyrazolopyridinone core led to discovery of a new series of potent KAT II inhibitors with excellent physicochemical properties. Compound 20 is the most potent
本文描述了新的吡唑系列不可逆KAT II抑制剂的基于结构的设计,合成和生物学评估。从二氢喹啉酮核心到四氢吡唑并吡啶并酮核心的1和2抑制剂骨架的修饰导致发现了一系列新的有效KAT II抑制剂,这些抑制剂具有出色的理化性质。在这些新的吡唑类似物中,化合物20是最有效和亲脂性最强的化合物,其k inact / K i值为112,000 M -1 s -1,亲脂性效率(LipE)为8.53。X射线晶体结构为20 KAT II的使用证明了有助于实现这种非凡效能和结合效率的关键功能。
