report the synthesis and biological evaluation of new 3,5-bis(2-indolyl)pyridine and 3-[(2-indolyl)-5-phenyl]pyridine designed as potential CDK inhibitors. Indole, 5-hydroxyindole, and phenol derivatives were used to generate three substitutions of the pyridine. The resulting skeletons were successively exploited to introduce various dimethylaminoalkyl side chains by Williamson type reactions. The synthesis
我们在这里报告了新型3,5-双(2-吲哚基)吡啶和设计为潜在CDK抑制剂的3-[(2-吲哚基)-5-苯基]吡啶的合成和生物学评估。吲哚,5-羟基吲哚和苯酚衍生物用于生成吡啶的三个取代基。通过威廉姆森(Williamson)型反应,依次利用所得骨架引入各种二甲基氨基烷基侧链。合成包括在3,5-二溴吡啶上实现的Stille或Suzuki型反应。还描述了斯坦尼多度在单或双交叉偶联反应中的制备和使用,并对每个步骤进行了优化和详细说明。实现了激酶测定法,结果表明,裸化合物7、18和25在0.3-0.7微摩尔范围内抑制CDK1,对GSK-3具有良好的选择性。用5-15微摩尔范围内的IC(50)值评估了对CEM人白血病细胞的细胞毒性。描绘了精确的构效关系。提出了分子建模和对接解决方案以完成研究并解释CDK分析中观察到的SAR。
