SB-277011 dihydrochloride (SB-277011A dihydrochloride) is a potent, selective, orally bioavailable and brain penetrate dopamine D3 receptor antagonist, with pKis of 8.0, 6.0, <5.2 and 5.9 for D3, D2, 5-HT1B, and 5-HT1D receptors, respectively.
SB-277011 dihydrochloride is a potent, selective, orally bioavailable and brain penetrate dopamine D3 receptor antagonist, and restores ≥100-fold selectivity against the D2, 5-HT1B, and 5-HT1D receptors, with pKis of 8.0, 6.0, <5.2 and 5.9 for D3, D2, 5-HT1B, and 5-HT1D receptors, respectively[1].
SB-277011 dihydrochloride (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[1].
