examining the effects of such modifications in both the central core constrain and the substituent beta to the carboxylate. Most of these derivatives were prepared in good yields through a cesium fluoride-catalyzed coupling reaction. This reaction was successful with a variety of nitrogen-containing scaffolds (20, 33, and 43) and selected acetylenic derivatives (16, 19, and 34). Among the compounds synthesized
铅化合物和药物与人血清白蛋白(HSA)的结合是药物发现中普遍存在的问题,因为它可以调节铅和药物对预期目标的可利用性,这与生物学功效有关。在我们不断努力确定小分子alpha(V)beta(3)和alpha(V)beta(5)双重拮抗剂的过程中,我们最近将吲哚2-4报告为有效的和选择性的alpha(V)beta(3)/ alpha( V)beta(5)拮抗剂具有良好的口服生物利用度。尽管这些化合物对人alpha(V)beta(3)和alpha(V)beta(5)整联蛋白的亚纳摩尔摩尔结合亲和力,但高HSA结合(96.5-97.3%)却成为这些引线的限制性特征。文献中报道的有机酸的结构活性HSA结合数据已证明,将极性基团并入给定的分子可以显着降低对HSA的亲和力。我们试图通过研究这种修饰在中心核心约束和对羧酸盐的取代基β中的作用来应用这种策略。这些衍生物大多数是通过氟化铯催化的偶联反应以高收率制
