描述：RIPA-56 is a highly potent, selective, and metabolically stable inhibitor of receptor-interactingprotein 1 (RIP1) with an IC50 of 13 nM.

溶解性：10 mM in DMSO

体外研究：

RIPA-56 has a half-life of 128 min in human liver microsomal stability assays and an EC50 of 28 nM in TSZ-induced HT-29 necrosis assay. RIPA-56 also demonstrates potency in protection of murine L929 cells from TZ-induced necrosis (EC50=27 nM). RIPA-56 shows efficient inhibition of RIP1 kinase activity, with an IC50 of 13 nM and no inhibition of RIP3 kinase activity at a 10 μM concentration. RIPA-56 could form tight hydrophobic interactions with RIP1 through both the phenyl group and the 2,2-dimethylbutyl group, and form two important hydrogen bonds.

体内研究：In the SIRS mice disease model, RIPA-56 efficiently reduces tumor necrosis factor alpha (TNFα)-induced mortality and multi-organ damage. Compared to known RIP1 inhibitors, RIPA-56 is potent in both human and murine cells, is much more stable in vivo, and is efficacious in animal model studies. RIPA-56 has an impressive PK profile in mice with a 3.1 h half-life, 22% oral bioavailability (P.O.), and 100% bioavailability from intraperitoneal injection (I.P.).
