ω-(5-Phenyl-2H-tetrazol-2-yl)alkyl-substituted hydrazides and related compounds as inhibitors of amine oxidase copper containing 3 (AOC3).

Arch Pharm (Weinheim) 2022 May 4:e2200111. Epub 2022 May 4.

Institute of Pharmaceutical and Medicinal Chemistry, University of Münster, Münster, Germany.

Amine oxidase copper containing 3 (AOC3), also known as plasma amine oxidase, semicarbazide-sensitive amine oxidase, or vascular adhesion protein-1, catalyzes the oxidative deamination of primary amines to aldehydes using copper and a quinone as cofactors. Because it is involved in the transmigration of inflammatory cells through blood vessels into tissues, AOC3 is thought to play an important role in inflammatory diseases. Therefore, inhibitors of this enzyme could lead to new therapeutics for the treatment of inflammation-related diseases. Read More
