oral VEGFR-2 inhibitors that provide sustained ocular retention and efficacy in models of wet-AMD. We disclose herein the synthesis and the biological evaluation of a series of novel core replacements as an expansion of the reported indole based VEGFR-2 inhibitor series. Addition of heteroatoms to the existing core and/or rearranging the heteroatoms around the 6–5 bicyclic ring structure produced a series
抗VEGF治疗已成为年龄相关性黄斑变性(AMD)的临床验证治疗方法。我们最近报道了基于吲哚的口服VEGFR-2抑制剂的发现,该抑制剂可在湿性AMD模型中提供持续的眼部保留和功效。我们在此公开了一系列新颖的核心替代物的合成和生物学评估,以作为已报道的基于吲哚的VEGFR-2抑制剂系列的扩展。在现有的核上添加杂原子和/或在6-5双环结构周围重新排列杂原子,产生了一系列化合物,这些化合物通常保留了良好的靶向作用力并改善了溶解度。已证明hERG亲和力不依赖于通过核心结构改变的亲脂性变化。这类化合物的体外/体内特性。
