化合物 SB-277011 HYDROCHLORIDE

SB-277011 hydrochloride has an excellent pharmacokinetic profile, exhibits oral bioavailability 43%, half-life:2.0 h, plasma clearance 19 mL/min/kg) and to be highly brain-penetrant (brain:blood ratio of 3.6:1), with a clean P450 profile in the rat.SB-277011 hydrochloride (SB 277011; 3 mg/kg, p.o.) completely reverses the effects of quinelorane in the nucleus accumbens, but does not reverse the effects of quinelorane in the striatum at 93 mg/kg in rats.SB-277011 (intraperitoneal injection; 12.5-25 mg/kg) significantly and dose-dependently reduces intravenous cocaine self-administration under both low fixed-ratio and progressive-ratio reinforcement conditions in rats. When it increases to 50 mg/kg, SB-277011 can significantly inhibit basal and cocaine-enhanced locomotion in rats.
