A novel series of pyrrolidine-constrained phenethylamines were developed as dipeptidyl peptidase IV (DPP4) inhibitors for the treatment of type 2 diabetes. The cyclohexene ring of lead-like screening hit 5 was replaced with a pyrrolidine to enable parallel chemistry, and protein co-crystal structural data guided the optimization of N-substituents. Employing this strategy, a >400x improvement in potency
开发了一系列新型的吡咯烷约束的苯乙胺作为二肽基肽酶IV(DPP4)抑制剂,用于治疗2型糖尿病。铅样筛选产物5的环己烯环被吡咯烷取代,以实现平行化学,蛋白质共晶体结构数据指导N取代基的优化。通过采用这种策略,以较快的速度实现了比初始命中高出400倍的效能提升。优化的化合物是具有出色药代动力学特征的有效和选择性抑制剂。化合物30在体内是有效的,可降低ZDF大鼠的血糖,该大鼠可自由进食混合餐。
