RB 101 suppresses enkephalinase and aminopeptidases; biologically cleaved at disulfide to produce inhibitors of both aminopeptidase N and neutralendopeptidase.
Azidothiorphan is a photoaffinity ligand for the active site of the neutralendopeptidase 24.11. After ultraviolet irradiation the inhibitor binds irreversibly to the enzyme, and photolabeling occurs at the active site. The competitive inhibitor thiorphan protects the endopeptidase from inactivation.
Aminopeptidase N (AP-N) inhibitor is a reversible inhibitor of AP-N/CD13 (IC50 = 25 μM). It is selective for AP-N/CD13 over matrix metalloproteinase-9 (MMP-9), angiotensin converting enzyme (ACE), neutralendopeptidase (NEP), γ-glutamyl transpeptidase, and the serine proteases dipeptidyl peptidase 4 (DPP-4) and cathepsin G at a concentration of 1 mM. AP-N inhibitor is non-cytotoxic to U937 cells at a concentration of 100 μM.
Potent and selective bradykinin B1 receptor agonist (EC50 = 9.02 nM in rabbit aorta) that is resistant to aminopeptidase, kininase I and II (ACE) and neutralendopeptidase cleavage. Exhibits hypotensive and angiogenic activity in vivo.
Sampatrilat is an effecive and orally active vasopeptidase inhibitor of ACE and neutralendopeptidase. Sampatrilat inhibits C-domain ACE (Ki=13.8 nM) 12.4-fold more potent than that for the N-domain (Ki=171.9 nM).
GLP-1(28-36)amide, a C-terminal nonapeptide derived from the cleavage of GLP-1 by neutralendopeptidase (NEP), is a significant product. It functions as an antioxidant and primarily targets the mitochondrion, where it effectively inhibits mitochondrial permeability transition (MPT). This compound exhibits anti-diabetic properties and demonstrates cardioprotection effects[1].
SCH-42354 is a potent, orally active inhibitor of neutralendopeptidase (NEP), serving as the active form of the prodrug SCH-42495. By inhibiting NEP hydrolysis, SCH-42354 enhances the activity of atrial natriuretic peptide (ANP) and prevents the hydrolysis of leu-enkephalin and ANF with IC50 values of 8.3 nM and 10.0 nM, respectively. Furthermore, SCH-42354 exhibits antihypertensive activity [1] [2].
