ole NPY Y5 receptor antagonists are described. Optimization of the lead compound 2a by incorporating substituents into the 5-position or into both the 5- and 6-positions of the benzimidazole core part led to the identification of 5-(5-methyl-1,2,4-oxadiazol-2-yl)benzimidazole (2r: IC(50)=3.3 nM) and 5-(2-methyltetrazol-5-yl)benzimidazole (2u: IC(50)=5.9 nM), both of which are potent, selective, and
描述了新型的2- [3-氧杂螺[异苯并呋喃-1(3H),1'-环己基] -4'-基]苯并咪唑NPY Y5受体拮抗剂的合成及其构效关系。通过将取代基并入苯并咪唑核心部分的5位或5位和6位两者中来优化前导化合物2a导致鉴定出5-(5-甲基-1,2,4-恶二唑-2 -基)苯并咪唑(2r:IC(50)= 3.3 nM)和5-(2-甲基四唑-5-基)苯并咪唑(2u:IC(50)= 5.9 nM),两者都是有效的,选择性的和口服的可生物利用的Y5受体拮抗剂。
