Actions biochimiques/physiologiques

RIPA-56 is a metabolically stable type III kinase inhibitor that targets receptor-interacting protein 1 kinase (RIP1; RIPK1) in a highly potent and selective manner (RIP1 IC50 = 13 nM) by locking RIP1 in its inactive form, exhibiting no inhibitory potency toward RIP3, IDO or a panel of multiple kinases (tested at 10, 200, and 5 μM, respectively). RIPA-56 protects against TNFα-induced necroptosis (necrosis) upon apoptosis/NF-κB pathway blockage (EC50 = 27 nM/murine L929 and 28 nM/human HT-29 cells) in cultures as well as TNFα-induced mortality and multiorgan damage in a murine model of systemic inflammatory response syndrome (SIRS) in vivo (100% survival rate with 3 mg/kg/12 h or single 6 mg/kg i.p.) with good pharmacokinetics and bioavailability (F post 10 mg/kg p.o. or i.p. dosing = 22% and 100%, respectively, of 2 mg/kg i.v.). Long-term daily RIPA-56 supplementation (150 or 300 mg/kg in chow) is reported to prevent aging-associated deterioration of the male reproductive system in mice.

We report the development of novel Mixed Lineage Kinase Domain-Like protein (MLKL) inhibitors with single nanomolar potency (compound 15 is also named as TC13172). Using the converting biochemistry to chemistry activity-based protein profiling (BTC-ABPP) method, we were able to determine

On the basis of its essential role in driving inflammation and disease pathology, cell necrosis has gradually been verified as a promising therapeutic target for treating atherosclerosis, systemic inflammatory response syndrome (SIRS), and ischemia injury, among other diseases. Most necrosis

A pair of kinases, RIPK1 and RIPK3, as well as the RIPK3 substrate MLKL cause a form of programmed necrotic cell death in mammals termed necroptosis. We report here that male reproductive organs of both Ripk3- and Mlkl-knockout mice retain
