A series of pyrrolidinones derived from phenylalaninepiperazines were synthesized and characterized as potent and selective antagonists of the melanocortin-4 receptor. In addition to their high binding affinities, these compounds displayed high functional potencies. 12a had a K(i) of 0.94 nM in binding and IC(50) of 21 nM in functional activity. 12a also demonstrated efficacy in a mouse cachexia model.
合成了一系列源自苯丙氨酸哌嗪的吡咯烷酮，并将其表征为强效且选择性的黑皮质素-4受体拮抗剂。除了具有高结合亲和力外，这些化合物还表现出高功能活性。12a的结合解离常数（K(i)）为0.94 nM，功能活性的半数抑制浓度（IC(50)）为21 nM。12a在小鼠恶病质模型中也显示出疗效。
