Abz-FR-K (Dnp) -P-OH

This small molecule is a highly efficient substrate for angiotensin I-converting enzyme (ACE), exhibiting a Km of 4.0 μM and a kcat of 210 s−1. It is widely used in vitro for kinetic assays and inhibitor screening to study cardiovascular and renal systems, facilitating research into hypertension and heart failure pathways.
