| + | [https://www.uniprot.org/uniprot/ACE_HUMAN ACE_HUMAN] Genetic variations in ACE may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:[https://omim.org/entry/601367 601367]; also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors.<ref>PMID:15534175</ref> Defects in ACE are a cause of renal tubular dysgenesis (RTD) [MIM:[https://omim.org/entry/267430 267430]. RTD is an autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).<ref>PMID:16116425</ref> Genetic variations in ACE are associated with susceptibility to microvascular complications of diabetes type 3 (MVCD3) [MIM:[https://omim.org/entry/612624 612624]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Defects in ACE are a cause of susceptibility to intracerebral hemorrhage (ICH) [MIM:[https://omim.org/entry/614519 614519]. A pathological condition characterized by bleeding into one or both cerebral hemispheres including the basal ganglia and the cerebral cortex. It is often associated with hypertension and craniocerebral trauma. Intracerebral bleeding is a common cause of stroke.<ref>PMID:15277638</ref> | ||

| + | [https://www.uniprot.org/uniprot/ACE_HUMAN ACE_HUMAN] Converts angiotensin I to angiotensin II by release of the terminal His-Leu, this results in an increase of the vasoconstrictor activity of angiotensin. Also able to inactivate bradykinin, a potent vasodilator. Has also a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety. | ||

| + | == Publication Abstract from PubMed == | ||
| + | Dual angiotensin-converting enzyme (ACE) and neprilysin (NEP) inhibitors such as omapatrilat showed promise as potent treatments for hypertension but produced adverse effects due to their high affinity for both domains of ACE (nACE and cACE). This led to the search for compounds that retained NEP potency but selectively inhibit cACE, leaving nACE active to degrade other peptides such as bradykinin. Lisinopril-tryptophan (LisW) has previously been reported to have cACE selectivity. Three mercapto-3-phenylpropanoyl inhibitors were synthesized, combining features of omapatrilat and LisW to probe structural characteristics required for potent dual cACE/NEP inhibition. We report the synthesis of these inhibitors, enzyme inhibition data, and high-resolution crystal structures in complex with nACE and cACE. This provides valuable insight into factors driving potency and selectivity and shows that the mercapto-3-phenylpropanoyl backbone is significantly better for NEP potency than a P(1) carboxylate. Future chemistry efforts could be directed at identifying alternative chemotypes for optimization of cACE/NEP inhibitors. | ||
