包含苯并咪唑而不是在AT 2 R 配体例如AT 2 R 激动剂C21 中常见的咪唑环的配体可以提供高亲和力和受体选择性。特别地,包括苯并咪唑的化合物,在 2 位被小体积基团取代,例如异丙基 ( K i = 4.0 nM) 或叔丁基 ( K i = 5.3 nM) 或噻唑杂环 ( K i = 5.1 nM) 表现出高亲和力和 AT 2 R 选择性。AT 1中的正丁基链R 选择性沙坦,使配体的受体选择性降低。迄今为止报道的大多数 AT 2 R 选择性配体中存在的联芳基支架上的异丁基最初来源于非选择性强效 AT 1 R/AT 2 R 配体 L-162,313。值得注意的是,在本文讨论的所有配体中,异丁基被正丙基取代,并且提供了对AT 2 R具有高亲和力的配体,此外它们中的大多数表现出良好的AT 2 R/AT 1 R选择性。在不同位置引入氟原子对亲和力数据没有明显影响。带有噻唑或叔叔的配体连接到

NaHSO3 was more than 11 equivalents, the 2-substituted benzimidazole could be highly selectively formed as the sole product. NaHSO3 was firstly reacted with aldehyde to form the aldehyde sodium bisulfite, which reacted with o-phenylenediamine to form the 2-substituted benzimidazole and inhibited the formation of 1,2-disubstituted benzimidazole. This protocol solved the poor selectivity problem appearing
