    WEHI-345 purchased from MCE. Usage Cited in: Mol Cell. 2018 Feb 15;69(4):551-565.e7.

    THP1 cells are treated with muramyl dipeptide (MDP) for 30 min in the presence or absence of indicated kinase inhibitors (1 mM; added 1 hr prior) followed by lysis in 6 M urea buffer. Lysates are immunoprecipitated with K63 and linear ubiquitin chain antibodies, and precipitates and lysates are examined by western blotting using indicated antibodies.

    WEHI-345 is a potent and selective inhibitor of RIPK2, with IC50 of 0.13 μM. IC50 value: 0.13 μM Target: RIPK2 in vitro: WEHI-345 is a selective RIPK2 kinase inhibitor, which delays RIPK2 ubiquitylation and NF-κB activation downstream of NOD engagement. WEHI-345 is an ATP analogue and was therefore predicted to bind in the ATP-binding pocket of RIPK2. WEHI-345 proved to be highly specific for RIPK2(Kd=46 nM) and displayed negligible activity (>10 μM) against RIPK1, RIPK4 and RIPK5. in vivo: WEHI-345 inhibits NOD signalling and has a beneficial effect on an EAE model. WEHI-345 blocks MDP-induced cytokine production. WEHI-345 ameliorates experimental autoimmune encephalomyelitis in mice. WEHI-345 also potently inhibited MDP-induced cytokine and chemokine secretion in the mouse macrophage Raw 264.7 cell line.
