Migration of the methylene imidazole side chain in the first reported selective drug-like AT2 receptor agonist C21/M024 (1) delivered the AT2 receptor antagonist C38/M132 (2). We now report that the AT2 receptor antagonist compound 4, a biphenyl derivative that is structurally related to 2, is transformed to the agonist 6 by migration of the isobutyl group. The importance of the relative position of
亚甲基咪唑侧链在第一个报道的选择性药物样AT 2受体激动剂C21 / M024(1)中的迁移提供了AT 2受体拮抗剂C38 / M132(2)。现在我们报告AT 2受体拮抗剂化合物4,一种与2结构相关的联苯衍生物,通过异丁基的迁移转化为激动剂6。本文突出了亚甲基咪唑和异丁基取代基的相对位置的重要性。
