  摘要：

  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

  A novel series of potent and selective alpha(v)beta(3)/alpha(v)beta(5) dual inhibitors was designed, synthesized, and evaluated against several integrins. These compounds were synthesized through a Mitsunobu reaction between the guanidinium mimetics and the corresponding central templates. Guanidinium mimetics with enhaced rigidity (i.e., (2-pyridylamino)propoxy versus the 2-(6-methylamino-2-pyridyl)ethoxy) led to improved activity toward alpha(v)beta(3). Exemplary oral bioavailability in mice was achieved using the indole central scaffold. Although, oral bioavailability was maintained when the indole molecular core was replace with the bioisosteric benzofuran or benzothiophene ring systems, it was found to not significantly impact the integrin activity or selectivity. However, the indole series displayed the best in vivo pharmacokinetic properties. Thus, the indole series was selected for further structure-activity relationships to obtain more potent alpha(v)beta(3)/alpha(v)beta(5) dual antagonist with improved oral bioavailability.

  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
