Background:

RTI-13951-33 is a potent, selective, and brain-penetrant GPR88 agonist, with an EC50 of 25 nM in GPR88 cAMP functional assay. RTI-13951-33 reduces alcohol reinforcement and intake behaviors in rats[1].

RTI-13951-33 is a potent, selective, and brain-penetrant GPR88 agonist, with an EC50 of 25 nM in GPR88 cAMP functional assay. RTI-13951-33 elevates [35S]-GTPγS binding (EC50, 535 nM) in mouse striatal membranes but not in membranes from GPR88 KO mice[1].RTI-13951-33 has weak affinities at kappa opioid receptor (KOR; Ki, 2.29 μM), vesicular monoamine transporter (VMAT; Ki, 4.23 μM), and moderate affinity at serotonin transporter (SERT; Ki, 0.75 μM), however, RTI-13951-33 poorly inhibits SERT (IC50, 25.1±2.7 μM)[1].

RTI-13951-33 (10 and 20 mg/kg, i.p.) dose-dependently decreases alcohol lever responses in a rat model of alcohol self-administration[1].RTI-13951-33 (10 mg/kg, i.p.) has sufficient brain penetration, with t1/2 of 48 min and 87 min in rat plasma and brain[1].
