On June 23, 2021, Fang, Yuying; Chen, Xiucai; Tan, Qingyun; Zhou, Huihao; Xu, Jun; Gu, Qiong published an article.Name: 8-Methoxy-3,4-dihydroisoquinolin-1(2H)-one The title of the article was Inhibiting Ferroptosis through Disrupting the NCOA4-FTH1 Interaction: A New Mechanism of Action. And the article contained the following:

Ferroptosis is an iron-dependent form of oxidative cell death, and the inhibition of ferroptosis is a promising strategy with which to prevent and treat neurol. diseases. Herein we report a new ferroptosis inhibitor 9a(I) with a novel mechanism of action. It is demonstrated that nuclear receptor coactivator 4 (NCOA4), a cargo receptor for ferritinophagy, is the target of 9a. Compound 9a blocks ferroptosis by reducing the amount of bioavailable intracellular ferrous iron through disrupting the NCOA4-FTH1 protein-protein interaction. Further studies indicate that 9a directly binds to recombinant protein NCOA4383-522 and effectively blocks the NCOA4383-522-FTH1 interaction. In a rat model of ischemic stroke, 9a significantly ameliorates the ischemic-refusion injury. With the first ligand 9a, this work reveals that NCOA4 is a promising drug target. Addnl., 9a is the first NCOA4-FTH1 interaction inhibitor. This work paves a new road to the development of ferroptosis inhibitors against neurol. diseases. The experimental process involved the reaction of 8-Methoxy-3,4-dihydroisoquinolin-1(2H)-one(cas: 74904-29-3).Name: 8-Methoxy-3,4-dihydroisoquinolin-1(2H)-one
