Resorcinolnaphthalein is a specific angiotensin-converting enzyme 2 (ACE2) enhancer and activates ACE2 activity with an EC 50 value of 19.5 μM. Resorcinolnaphthalein can be used for the investigation of hypertension and renal fibrosis In Vitro Resorcinolnaphthalein (100 μM) and XNT enhances ACE2 activity in a dose-dependent manner with EC 50 values of 19.5 μM and 20.1 μM, respectively. ACE2 is an effective enzyme in attenuating fibrosis and structural remodeling. Enhancement of ACE2 activity has beneficial effects on the cardiovascular system and protects against hypertension induced pathophysiology. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:EC50: 19.5 μM (ACE2)
