AA9 Usage And Synthesis

Uses

SRS11-92, a Ferrostatin-1 (Fer-1) analogue, is a potent ferroptosis inhibitor. SRS11-92 inhibits ferroptotic cell death induced by Erastin in HT-1080 human fibrosarcoma cells (EC50=6 nM)[1].

Definition

ChEBI: SRS11-92 is an ethyl ester resulting from the formal condensation of the carboxy group of 3-(benzylamino)-4-(cyclohexylamino)benzoic acid with ethanol. It is a potent inhibitor of ferroptosis induced by erastin in HT-1080 human fibrosarcoma cells (EC50 = 6 nM). It has a role as a ferroptosis inhibitor. It is a substituted aniline, an ethyl ester, a secondary amino compound and a diamine. It is functionally related to a ferrostatin-1.

Biological Activity

SRS11-92 is a cell penetrant and potent inhibitor of ferroptosis th at attenuates the cell death associated with frataxin knockdown in healthy human fibroblasts. SRS11-92 protects against cell death in in a brain slice model of Huntington′s disease, an oligodendrocyte model of periventricular leukomalacia, and in isolated kidney proximal tubules model of kidney disfunction.
