The present invention has multiple aspects. In its first aspect, it is directed to a compound that is a 4(S)-fluoro-thio-tripeptide analog that has the unexpectedly superior property of specifically inhibiting the enzyme, membrane-bound aminopeptidase P2 (APP2), whose natural substrate is bradykinin, but not the enzyme angiotensin converting enzyme (ACE) which also cleaves bradykinin. In its second aspect, the present invention is directed to a pharmaceutical composition comprising the 4(S)-fluoro-thio-tripeptide analog and a pharmaceutically acceptable carrier. In its third aspect, the invention is directed to a method of inhibiting bradykinin degradation in a mammalian patient, comprising administering a therapeutically effective amount of the compound of the invention to a mammalian patient in need of inhibition of bradykinin degradation.
本发明具有多个方面。在其第一个方面中,它针对一种化合物,即4(S)-氟硫代三肽类似物,具有意外优越的特性,能够特异性地抑制酶膜结合氨肽酶P2(APP2),其天然底物是激肽,但不抑制也能切割激肽的酶血管紧张素转换酶(ACE)。在其第二个方面中,本发明针对一种包含4(S)-氟硫代三肽类似物和药用可接受载体的药物组合物。在其第三个方面中,该发明针对一种抑制哺乳动物患者中激肽降解的方法,包括向需要抑制激肽降解的哺乳动物患者投予本发明化合物的治疗有效量。
