卡托普利二硫化物是LTA4水解酶（IC50 = 11 µM）的可逆竞争性抑制剂。卡托普利已被证明是血管紧张素转化酶-1（ACE1）的一种，而不是ACE2（IC | 50 | = 22 nM）。卡托普利分别证明了酪氨酸酶单酚酶和双酚酶活性的不可逆非竞争性和竞争性抑制剂。卡托普利还被证明可以抑制血管紧张素II的形成，血管紧张素II是一种生物活性肽，可刺激血管生成并增加微血管密度。 Captopril Disulfide is a reversible and competitive inhibitor of LTA4 hydrolase (IC50=11 μM). Captopril has been shown to be an of angiotensin converting enzyme-1 (ACE1), but not ACE2(IC|50|= 22 nM). Captopril demonstrates irreversible noncompetitive and competitive inhibitor of tyrosinase monophenolase and diphenolase activities, respectively. Captopril has also been shown to inhibit the formation of angiotensin II, a bioactive peptide that stimulates angiogenesis and increases microvessel density.
