Necrostatin-5 Chemical Properties,Usage,Production

Uses

Necrostatin-5 (Nec-5) is a potent necroptosis inhibitor with an EC50 value of 0.24 μM. Necrostatin-5 also is a RIP1 inhibitor. Necrostatin-5 shows cardioprotective effects[1][2][3].

Biological Activity

Necrostatin-5 is an inhibitor of necroptosis (non-apoptotic cell death pathway) by indirect inhibition of RIP1 kinase. Necroptosis is defined as alternative active cell death pathway: Death-Domain Receptor (DRs, e.g. Fas/TNFR) mediated and caspase-inhibitor insensitive with specific morphology (nuclear condensation, organelle swelling, loss of plasma membrane integrity). The necrostatins have been discovered to inhibit this pathway by inhibition of the death domain receptor-associated adaptor kinase RIP1. Three distinct mechanisms appear to be involved: T-loop dependent inhibition by necrostatin-1; partially T-loop independent inhibition by necrostatin-3 and indirect inhibition of RIP1 by necrostatin-5, since necrostatin-5 is a potent inhibitor of immunnoprecipitated RIP1, but does not inhibit recombinant RIP1.

in vivo

Necrostatin-5 (2.46 mg/kg; i.p.) shows cardioprotective effects on the isolated heart model in rats[2].

Animal Model:200-300 g, male Wistar rats[2]
Dosage:2.46 mg/kg
Administration:I.p.; 60 min before experiment
Result:Reduced the infarction zone caused by 30-min global ischemia and 120-min reperfusion.

IC 50

RIPK1; necroptosis: 0.24 μM (EC50)

storage
