A metabolite of Ramipril (R111000). | [Definition]
ChEBI: A dipeptide that is the active metabolite of ramipril. An angiotensin-converting enzyme (ACE) inhibitor, used to treat high blood pressure and congestive heart failure. | [Description]
Ramiprilat is the active metabolite of ramipril (Item No. 15558) and functions as an angiotensin-converting enzyme inhibitor (pKi = 9.08 in human heart) to suppress the conversion of angiotensin I to angiotensin II and the degradation of bradykinin, thereby preventing vasoconstriction.1,2 Furthermore, ramiprilat is reported to interfere with the targeting of B2 kinin receptors to endothelial cell membranes further preventing bradykinin signaling.2 In addition to its cardioprotective effects in both animal models and clinical studies, ramiprilat has been reported to inhibit matrix metalloproteinase-3 and -9 activity in isolated Crohn’s disease fistulas.3,4 | [in vitro]
pretreatment with ramiprilat could significantly attenuate the recovery of b2 kinin receptors in while increasing that from membranes lacking caveolin, and such effect was not because of the inhibition of bradykinin degradation. ramiprilat could also decrease [3h]bradykinin binding to cr membranes. in addition, ramiprilat treatment led to reactivation of the b2 receptor in bradykinin-stimulated cells [1]. | [in vivo]
in previous animal study, when compared with the control rats, diabetic rats showed decreased creatinine clearance rate, increased urinary protein excretion and blood pressure, as well as development of tubulointerstitial fibrosis, glomerulosclerosis, and inflammatory cell infiltration. furthermore, the blocking angiotensin ii with ramipril (the prodrug of ramiprilat) was able to significantly improve all of these parameters [2]. | [References]
