Angiotensin-converting enzyme 2 (ACE2) is an enzyme that is cardioprotective and renoprotective. Resorcinolnaphthalein increases the activity of ACE2 in vitro (EC50 = 19.5 μM). Activation of ACE2 in rats produces a decrease in blood pressure and improvement in cardiac function. In spontaneously hypertensive rats it produces a reversal of myocardial, perivascular, and renal fibrosis.[Cayman Chemical]
resorcinolnaphthalein is an angiotensin-converting enzyme 2 (ace2) activator [1].angiotensin-converting enzyme 2 (ace2) has been involved in hydrolyzing angiotensin ii and opposing its actions, and plays a protective role in the pathogenesis of pulmonary arterial hypertension (pah) [2]. targeted disruption of ace2 in mice results in a severe cardiac contractility defect, increased angiotensin ii levels, and upregulation of hypoxia-induced genes in the heart [2].
resorcinolnaphthalein enhanced ace2 activity in a dose-dependent manner [1].
resorcinolnaphthalein caused significant activation of ace2 in both normal and diseased rats in 7 days after treatment. treatment with resorcinolnaphthalein prevented high pap, right ventricular hypertrophy and neointimal formation. resorcinolnaphthalein caused an improved endothelia-dependent vasorelaxation and decreased in proinflammatory cytokines, such as tnf-α, mcp-1, il-6, and increased in anti-inflammatory cytokine il-10 in the early stage of the pathogenesis [3]. resorcinolnaphthalein can specifically and effectively enhanced ace2 activity in rats [4]. ace2 activation by resorcinolnaphthalein showed effects on pulmonary endothelial dysfunction and neointimal formation during the development of severe pah in rats [4].
