Sanglifehrin A 和 B 是免疫抑制性大环天然产物,具有独特的螺环内酰胺并由其区分。在此,我们报告了 sanglifehrin A 和 B 以及类似物的对映选择性全合成和生物学评价。获得螺环内酰胺是通过关键的吡喃酮中间体的会聚组装,然后是立体控制的螺环化来实现的。22 元大环核是在 2,6-双(三氟甲基)苯硼酸 (BFBB) 存在下通过闭环复分解合成的。螺环内酰胺和大环片段通过Stille偶联结合,以提供相思蛋白A和B。另外制备在C40位置具有变化的其它相思蛋白B类似物。生物学评价表明,2-CF 3在 Jurkat 细胞中,sanglifehrin B 的类似物表现出比天然产物 sanglifehrin A 和 B 更高的抗增殖活性。两种天然产物均诱导亲环蛋白 A (CypA) 的高阶同二聚化,但只有 sanglifehrin A 促进 CypA 与肌苷-5'-单磷酸脱氢酶 2
