6,7-Dihydro-5H-2,1-benzisoxazol-4-one analogs are potent inhibitors of aldosterone synthase (CYP11B2) with selectivity over the highly homologous enzyme cortisol synthase (CYP11B1). These compounds are unique among inhibitors of CYP11B2 in their lack of a strong-heme binding group such as a pyridine or imidazole. Poor metabolic stability in hepatocyte incubations was found to proceed via a reduction
6,7-Dihydro-5H-2,1-benzisoxazol-4-one类似物是有效的醛固酮合酶(CYP11B2)抑制剂,对高度同源的皮质醇合酶(CYP11B1)具有选择性。这些化合物在CYP11B2抑制剂中是独特的,因为它们缺少强血红素结合基团,例如吡啶或咪唑。发现通过减少异恶唑环来进行肝细胞培养中的不良代谢稳定性。虽然负责还原性代谢的酶仍是未知的,但是通过添加极性官能团可以降低代谢率。在体外CYP11B2效力和选择性被证实在体内通过ACTH的抑制食蟹猴模型中刺激醛固酮产生,而不会影响血浆皮质醇浓度。
