– Angiotensin I/II (1-6) TFA is a chemical compound comprising amino acids 1-6, derived from the Angiotensin I/II peptide. This peptide is formed by the cleavage of angiotensinogen by renin, with Angiotensin I subsequently hydrolyzed by angiotensin-converting enzyme (ACE) to produce biologically active Angiotensin II. Angiotensin II has been extensively studied for its potential applications in the treatment of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].
