bis-beta-ethereal) into 1 gave more hydrophilic compounds, which had good affinity for the receptor. Introducing an amino group or shortening the alkyl side chain was detrimental to CRHR1 affinity. The alcohol 4-[ethyl[2,5,6-trimethyl-7-(2,4,6-trimethylphenyl)pyrrolo[2,3-d]pyrimidin-4-yl]amino]butan-1-ol (3), bearing a terminal hydroxyl group on an N-alkyl side-chain, showed the highest CRHR1 binding affinity among
与N-丁基-N-乙基[2,5,6-三甲基-7-(2,4,6-三甲基苯基)吡咯并[2,3-d]嘧啶-4-基]胺有关的一系列化合物(1 (antalarmin,antalarmin)已制备并评估其CRHR1结合亲和力,以此作为开发选择性高亲和力亲水非肽促肾上腺皮质激素释放激素1型受体(CRHR1)拮抗剂的第一步。计算的log P(Clog P)值用于评估这些类似物的亲水性等级顺序。将含氧官能团(δ-羟基或双-β-醚基)引入1得到更多的亲水化合物,该化合物对受体具有良好的亲和力。引入氨基或缩短烷基侧链不利于CRHR1亲和力。醇4- [乙基[2,5,6-三甲基-7-(2,4,6-三甲基苯基)吡咯并[2,3-d]嘧啶-4-基]氨基]丁-1-醇(3) ,在这些化合物中,在N-烷基侧链上带有末端羟基的化合物显示出最高的CRHR1结合亲和力(K(i)= 0.68 nM),并且是已知的最高亲和力的CRHR1
