Clear solution
5% DMSO 95% Corn oil
0.8mg/ml Taking the 1 mL working solution as an example, add 50 μL of 16 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Bromocriptine mesylate is a dopamine receptor agonist with a Ki of 12.2 nM for D3 receptor and D2 receptor and a Ki of 1659 nM, 59.7 nM, 1691 nM for D1 receptor, D4 receptor, and D5 receptor, respectively. Bromocriptine mesylate is used in the treatment of Parkinson's disease, hyperprolactinemia-associated dysfunctions, and acromegaly.

In vitro

Bromocriptine dose-dependently reduces the number of OH radicals. [1] Bromocriptine has a strong scavenging effect on the 5,5-dimethyl-1-pyrroline-N-oxide hydroxide signal produced from Fenton's reaction. Bromocriptine also attenuates the stable free radical diphenyl-p-picrylhydrazyl signal. [2]
In vivo

Bromocriptine (5 mg/kg, i.p., 7 days) completely protects against the decrease in mouse striatal dopamine and its metabolites induced by intraventricular injection of 6-hydroxydopamine after intraperitoneal administration of desipramine. [1] Bromocriptine (2.5 mg/kg, i.p., daily for 3 days) significantly reduces autooxidation of brain homogenates collected from rats. [2] Bromocriptine (12.5 mg/kg) produces mild dyskinesia over the course of the study that is significantly less severe than in the L-dopa-treated group in the MPTP-treated marmoset. Bromocriptine, has a lesser tendency than L-dopa to produce dyskinesia while similarly improving motor performance in drug-naive MPTP-treated marmosets. [3] Bromocriptine (10 μM and 10 mg/kg i.p.) blocks .OH formation caused by MPTP in vitro (20 μM) and in vivo (30 mg/kg i.p.) in mice. Bromocriptine reduces an MPTP-induced increase in the activity of catalase and superoxide dismutase in substantia nigra on the seventh day. Bromocriptine blocks MPTP-induced behavioral dysfunction as well as glutathione and dopamine depletion, indicating its potent neuroprotective action. [4]
