| Hazard Information | Back Directory | [Uses]
MLN-4760 is a potent and selective human ACE2 inhibitor (IC50, 0.44 nM), with excellent selectivity (>5000-fold) versus related enzymes including human testicular ACE (IC50, >100 μM) and bovine carboxypeptidase A (CPDA; IC50, 27 μM). | [Definition]
ChEBI: MLN-4760 is a L-histidine derivative that is L-histidine in which a hydrogen of the primary amino group is substituted by a (1S)-1-carboxy-3-methylbutyl group and the ring NH group is substituted by a 3,5-dichlorobenzyl group. It is a potent and selective human angiotensin-converting enzyme 2 (ACE2) inhibitor (IC50 = 0.44 nM) which was in clinical development for the treatment of ulcerative colitis. It has a role as an anti-inflammatory agent and an EC 3.4.17.23 (angiotensin-converting enzyme 2) inhibitor. It is a L-histidine derivative, a dichlorobenzene and a L-leucine derivative. | [Biological Activity]
MLN-4760 is bioavailable and exhibits far greater selectivity for carboxypeptidase (IC50 = 0.44 nM against 50 pM human ACE2; [ZnCl2] = 10 μM[MCA-APK(DNP)] = 50 μM) over bovine carboxypeptidase A or ACE peptidyldipeptidase activity (IC50 = 27 μM and >100 μM against 0.5 nM bovine CPDA and 1 nM porcine ACErespectively; [Substrate] = 50 μM) and porcine ACE (IC50 = 27 and >100 μMrespectively). This reversible ACE2 inhibitor binds to the active site zinc with high-affinity and emulates the transition state during peptide hydrolysis. It reduces serum and kidney ACE 2 activity and abolishes angiotensin II-induced hypertension in mice. MLN-4760 selectively blocks angiotensin (ANG-(1-7)) formation in ACE2 wild type (WT) mice subjected to low ANG II concentrations (<0.1 μM)but at higher ANG II concentrations it does not affect ANG -(1-7) levels in mice. This ACE2 inhibitor enhances tumor necrosis factor (TNF) (10 pg/mL) stimulated exp | [in vivo]
MLN-4760 (100 μM, intracerebroventricular infusion for five days) significantly worsens neurological function at 4 h and 3 d post-stroke without significantly increasing infarct volume[3]. | [storage]
