We previously reported a series of 8-methyl-2-aryl-5-alkylaminoquinolines as a novel class of corticotropin-releasing factor-1 (CRF1) receptor antagonists. A critical issue encountered for this series of compounds was low aqueous solubility at physiological pH (pH 7.4). To address this issue, derivatization at key sites (R2, R3, R5, R5′, and R8) was performed and the relationships between structure
我们之前报道了一系列8-甲基-2-芳基-5-烷基
氨基
喹啉,它们是一类新的促
肾上腺皮质激素释放因子1(CRF 1)受体拮抗剂。该系列化合物遇到的一个关键问题是在生理pH(pH 7.4)下的低
水溶性。为了解决该问题,进行了关键部位(R 2,R 3,R 5,R 5'和R 8)的衍生化,并研究了结构与溶解度之间的关系。结果表明,在C 8位上引入甲氧基取代基对衍
生物的溶解度具有积极的影响。因此,通过体内和体外
生物学研究,21d被鉴定为具有改善的理化性质的有效的口服活性CRF 1受体拮抗剂。
