The present invention is directed to an α thio-containing compound that is capable of inhibiting the enzyme, membrane aminopeptidase P (mAPP or APP), whose natural substrate is bradykinin. The compound is useful as a pharmaceutical agent because by inhibiting bradykinin degradation, the compound allows bradykinin to exert its beneficial effects on the cardiovascular system, to improve renal function, and to improve glucose tolerance and insulin-sensitivity. The present invention is also directed to a pharmaceutical composition comprising the mAPP inhibitor of the present invention and a pharmaceutically acceptable carrier. In another aspect, the present invention is directed to a method of inhibiting bradykinin degradation in a mammalian patient, preferably human, in need of treatment comprising administering to the patient a therapeutically effective amount of an α thio-containing compound of the present invention. The method of the present invention also contemplates the further step of administering to the mammalian patient in need of treatment a therapeutically effective amount of an inhibitor of angiotensin converting enzyme (ACE).
本发明涉及一种含α硫基的化合物,能够抑制酶、膜氨肽酶P(mAPP或APP),其天然底物为激肽。该化合物可用作药物代理,因为通过抑制激肽降解,使激肽能够在心血管系统上发挥其有益作用,改善肾功能,并改善葡萄糖耐量和胰岛素敏感性。本发明还涉及一种含有本发明mAPP抑制剂和药用可接受载体的药物组合物。另一方面,本发明涉及一种在需要治疗的哺乳动物患者,优选为人类,中抑制激肽降解的方法,包括向患者投予本发明的α硫基化合物的治疗有效量。本发明的方法还包括向需要治疗的哺乳动物患者投予抑制肾素转化酶(ACE)的治疗有效量的进一步步骤。
