PK68 (RIPK1 inhibitor PK68) is a potent necroptosis inhibitor seletively targeting RIPK1 kinase activity, potently inhibits TNF-induced necroptosis (EC50, 23 and 13 nM in human and mouse cells, respectively).PK68 blocks cellular activation of RIPK1, RIPK3, and MLKL upon necroptotic stimuli.PK68 is a type II inhibitor of RIP1 kinase, highly selective inhibitor of RIPK1 kinase activity with IC50 of 90 nM, does not affect RIPK3 kinase activity at 1 uM, also demonstrated a reasonable selectivity against a panel of 369 kinases.PK68 exhibits a favorable pharmacokinetic profile and no obvious toxicity in mice.PK68 ameliorates TNF-induced systemic inflammatory response syndrome, and displays preventive suppression of tumor metastasis in the mouse cancer models.
