Bromocriptine stimulates [35S]-GTPγS binding at D2 dopamine receptor expressed in CHO cells with pEC50 of 8.15±0.05[1]. Bromocriptine also is a strong inhibitor of brain nitric oxide synthase. The ergot alkaloid Bromocriptine (BKT) is found to act as a strong inhibitor of purified neuronal nitric oxide synthase (NOS) (IC50=10±2 μM) whereas it is poorly active towards inducible macrophage NOS (IC50>100 μM) [2]. Bromocriptine is found to inhibit the activity of at least one human cytochrome P450 enzyme. Bromocriptine is a potent inhibitor of CYP3A4 with a calculated IC50 value for the interaction of 1.69 μM[3].

Protocol
The [35S]-GTPγS binding assay is carried out. Cell membranes (25 ±75 ug) are incubated in Buffer B containing 0.1 mM dithiothreitol (DTT) and 1 uM GDP and drugs in a volume of 0.9 mL for 30 min at 30°C. This preincubation ensures that the agonists tested are at equilibrium when the [35S]-GTPγS (50±150 pM, final concentration) is added (in 100 uL of Buffer B) to initiate the reaction. The assay mixture is incubated for a further 20 min unless otherwise stated. The assays are terminated by rapid filtration and bound radio-activity determined as described for the radio-ligand binding assays above. The total binding of [35S]-GTPγS is less than 20% of that added[1].

Mice[4]
Swiss mice (20-25 g) of either sex (total 150) are used. Bromocriptine mesylate is used as dopamine receptor (D2) agonist. Haloperidol is diluted in distilled water which is used for a vehicle of injection. Bromocriptine mesylate is dissolved in one drop of glacial acetic acid and made up to volume in distilled water. Imipramine is dissolved in 0.9% normal saline. Haloperidol (0.1 mg/kg, i.p.) and Bromocriptine mesylate (2 mg/kg, i.p.) are administered for 7 days in groups of mice in Forced Swimming Test (FST) and Tail Suspension Test (TST). Imipramine (10 mg/kg, p.o.) as a standard is administered in positive control groups for 7 days.
Rats[5]
Adult male Sprague-Dawley rats (N=112, 275-325 g) are used. Two weeks after the 6-OHDA injection, the animals are briefly (<3 min) anesthetized with 2 % halothane using a mask and received for intracisternal administration Bromocriptine (7 μg/kg dissolved in 5 μL vehicle) or the vehicle alone (5 μL of 0.9 % saline). For i.p. injection we used Bromocriptine (1 mg/kg) and SKF81297 (3 mg/kg dissolved in 0.9 % saline) concentrations. Following a recovery period (<2 min), the rats are placed in the observation field for 40 min period-test by a blind-experimenter.
