T-5342126

T-5342126 is a toll-like receptor 4 (TLR4) antagonist that reduces LPS-induced production of nitric oxide (NO) in RAW 264.7 cells (IC50 = 27.8 μM) and decreases LPS-induced IL-8, TNF-α, and IL-6 production in isolated human whole blood (IC50s = 110.5, 315.6, and 318.4 μM, respectively) . T-5342126 (82 mg/kg) also reduces ethanol intake and the abundance of ionized calcium-binding adapter molecule 1 (Iba1), a marker of microglial activation, in the central nucleus of the amygdala in ethanol-dependent mice.
