Novel phenethylpyridone derivatives were identified as potent human melanin-concentrating hormone 1 receptor (MCH-1R) antagonists. A search for surrogates for the 4-(2-aminoethoxy)phenyl moiety of 1 resulted in discovery of 2-[4-(aminomethyl)phenyl]ethyl substructure as in 6a. Successive optimization of the right-hand moiety led to the identification of a number of potent derivatives.
新型苯乙吡啶酮衍生物被鉴定为强效的人黑色素浓缩激素1受体(MCH-1R)拮抗剂。对化合物1的4-(2-氨基乙氧基)苯基部分进行替代物搜索,结果发现了如化合物6a中的2-[4-(氨基甲基)苯基]乙基亚结构。对右侧部分的连续优化导致了一系列强效衍生物的鉴定。
