IC50: 85 nM (GABAB receptor)[1]

In Vitro CGP52432 is a GABAB receptor antagonist, with an IC50 of 85 nM, 35- and 100-fold lower than at the receptors regulating somatostatin and glutamate overflow, respectively[1].
In Vivo CGP52432 (10, 30 mg/kg) shows no effect on the total arm entries and total head dips of mice on the elevated-plus maze[2]. CGP52432 (100 nmol/kg, i.v., or 1 nmol/kg, i.c.v.) abolishes the suppressive effects of GABA ( 50 μmol/kg, i.v.) on enhanced renal sympathetic nerve activity (RSNA) during ischaemia, causeing elimination of the renoprotective effects of GABA in rats[3].
Animal Admin Mice[2] Two separate cohorts of male pups are used for the study. One cohort is treated with either R(+)baclofen HCl (2 mg/kg) or with vehicle (PBS). The second cohort is treated with the GABAB receptor antagonist CGP52342 (10, 30 mg/kg) or vehicle (PBS). Drugs are freshly prepared for injection each day, by dissolution in PBS with vortexing and brief sonication. Doses of R(+)baclofen and CGP52432 are chosen to be well tolerated in adult mice. All drug treatments are given via subcutaneous injection, once daily from P14-28 in a volume of 0.05 mL[2].
