The synthesis and CRF receptor binding affinities of several new series of N-aryltriazolo- and -imidazopyrimidines and -pyridines are described. These cyclized systems were prepared from appropriately substituted diaminopyrimidines or -pyridines by nitrous acid, orthoester, or acyl halide treatment. Variations of amino (ether) pendants and aromatic substituents have defined the structure-activity relationships
描述了几种新系列的N-芳基三唑-和-咪唑并嘧啶和-吡啶的合成和CRF受体结合亲和力。这些环化体系是由适当取代的二氨基嘧啶或-吡啶通过亚硝酸,原酸酯或酰卤处理制得的。氨基(醚)侧基和芳族取代基的变化定义了这些系列的结构-活性关系,并导致鉴定出多种高亲和力试剂(Ki's <10 nM)。基于该性质和亲脂性差异,最初选择了其中的六个化合物(4d,i,n,x,8k,9a)用于大鼠药代动力学(PK)研究。良好的口服生物利用度,高血浆水平以及四种化合物的持续时间(4d,i,n,x)提示在静脉内和口服给药后都对狗进行了进一步的PK研究。这项工作的结果表明4i,x具有我们认为是潜在治疗剂所必需的特性,并且已选择4i1进行进一步的药理研究,并将在适当时候进行报道。
