IC50: 9 μM (ACE).
H-Val-Pro-Pro-OH, a proline peptides derivative, could inhibit Angiotensin I converting enzyme (ACE), with an IC 50 of 9 μM. H-Val-Pro-Pro-OH could enhance insulin sensitivity and prevent insulin resistance in 3T3-F442A pre-adipocytes. H-Val-Pro-Pro-OH also has anti-hypertensive and anti-inflammatory functions. H-Val-Pro-Pro-OH further enhances the expression of glucose transporter 4 (GLUT4) in adipocytes and restores glucose uptake in TNF-treated adipocytes.
