Chemical modification of aryl-1,2,3,6-tetrahydropyridinopyrimidine derivative to discover corticotropin-releasing factor1 receptor antagonists Aryl-1,2,3,6-tetrahydropyridino-purine, -3H-1,2,3-triazolo[4,5-d]pyrimidine, -purin-8-one, and -7H-pyrrolo[2,3-d]pyrimidine derivatives

6-tetrahydropyridinopyrimidine derivatives including potent CRF receptor ligands 1a-c, and proposed that the 4- or 5-aryl-1,2,3,6-tetrahydropyridino moiety might be useful as a substituent in the Up-Area. Our interest shifted to the chemical modification in which the pyrimidine ring of 1a-c was replaced by other heterocycles, purine ring of 2, 3H-1,2,3-triazolo[4,5-d]pyrimidine ring of 3, purin-8-one ring
非肽CRF(1)拮抗剂的结构亲和关系(SAR)表明,此类拮抗剂可以由三个单元构成:疏水单元(上区域),质子接受单元(中央区域)和芳族单元(下降区域)。最近,已经报道了通过修饰中央区域获得的各种非肽促肾上腺皮质激素释放因子(1)(CRF(1))受体拮抗剂。相比之下,我们修改了Up-Area并提出了包含有效CRF受体配体1a-c的4-或5-芳基-1,2,3,6-四氢吡啶并嘧啶衍生物,并提出了4-或5-芳基-1, 2,3,6-四氢吡啶基部分可以用作向上区域中的取代基。我们的兴趣转向化学修饰,其中1a-c的嘧啶环被其他杂环取代,即2、3H-1,2,3-三唑并[4,3的5-d]嘧啶环,4的嘌呤-8-环和5的7H-吡咯并[2,3-d]嘧啶环。其中,5-芳基-1,2,3,6-四氢吡啶基嘌呤化合物6j(CRA0186)对CRF(1)受体的亲和力最高(IC(50)= 20nM)。我们在这里报告衍生物6-9的合成和SAR。
