N1-Acetyl-5-methoxykynuramine (hydrochloride)

N1-Acetyl-5-methoxykynuramine (AMK) hydrochloride is an active metabolite of the neurohormone melatonin. N1-Acetyl-5-methoxykynuramine hydrochloride (200 µM) effectively scavenges singlet oxygen (ROS).1 It also inhibits the production of prostaglandin E2 (PGE2) and prostaglandin D2 (PGD2) induced by epinephrine and arachidonic acid in a concentration- and time-dependent manner, and suppresses the increase in COX-2 levels induced by LPS (HY-D1056) in RAW 264.7 macrophages at a concentration of 500 µM. In a mouse model of Parkinson's disease induced by MPTP (HY-15608), N1-Acetyl-5-methoxykynuramine hydrochloride (20 mg/kg) reduces the increase in lipid peroxidation in the cytosol and mitochondria of the substantia nigra and striatum. N1-Acetyl-5-methoxykynuramine hydrochloride can be used in research on metabolic and neurological diseases[1][2][3][4][5][6]
