N-(4-Fluorophenyl)-4-phenyl-2-thiazolamine

For GP130 receptor agonist-1 (Compound 2), mice are dosed orally at 10 or 30 mg/kg, or injected subcutaneously (SQ) at 10 mg/kg, and euthanized after 1, 2, 4, 6, and 8 h post dose. At 2 h after SQ delivery at 10 mg/kg the brain Cmax is 161 ng/g while dosing at 30 mg/kg orally, results in the brain Cmax of 156 ng/g (0.57 μM). The brain to plasma ratio for 2 is ～4:1 for oral 30 mg/kg and ～7.5:1 for 10 mg/kg SQ injection^[1].
