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), neutral endopeptidase (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.
HFI-142 是一种小分子抑制剂,能够特异性结合氨肽酶 N 的活性位点并抑制其酶活性。HFI-142 已被证明可抑制红细胞中白三烯 A4 的生物合成,该作用通过调控与肿瘤生长和进展相关的炎症及代谢通路,可能在癌症研究中具有治疗潜力。HFI-142 还可抑制其他氨肽酶的活性,包括氨肽酶 N 以及与蛋白质代谢相关的多种酶。
