CAS 55715-01-0: H-Ile-Arg-OH

The dipeptide IR showed a remarkable ACE- and renin-inhibitory activity.

L-Isoleucyl-L-arginine, a dipeptide composed of L-isoleucine and L-arginine, acts as a potent angiotensin-converting enzyme (ACE) inhibitor and is utilized in

H-Ile-Arg-OH acetate salt is an antioxidant that belongs to the group of amino acids. It has been shown to have antioxidative activity in vitro, as well as interaction with radicals and free radicals. Cryo-electron microscopy was used to show this compound's radical scavenging activity. H-Ile-Arg-OH acetate salt has also been found to have antioxidative properties in eukaryotes. This compound is composed of two isomers: H-Ile and Arg. The hydroxyl group on the H-Ile isomer gives this compound its antioxidative properties, while the Arg isomer possesses hydrolytic properties. The subunits are linked together by a peptide bond between the carboxyl group on Arg and the amine group on H-Ile. In addition, H-Ile has an -OH hydroxyl group that can be scavenged by hydroxyl radicals, which provides antioxidative activity.
