Molarity Calculator

GBR 12935 dihydrochloride is a potent, and selective dopamine reuptake inhibitor, with the binding constant (K_d) of 1.08 nM in COS-7 cells. GBR 12935 dihydrochloride stimulates the locomotion activity in different mice strains but fails to induce stereotypy. Thus, GBR 12935 dihydrochloride also prevents the d-Fenfluramine-induced head-twitch response in mice.

Description

In Vitro

GBR 12909 (10-100 nM) also shows a high affinity for CYP2D6 with the K_d value of 42.2 nM, lower than the affinity for dopamine transporter. The binding effect can be reduced by Quinidine (HY-B1751) and Quinine (HY-D0143), which are the specific and potent inhibitors of CYPZD enzymatic activities^[1].
GBR 12935 dihydrochloride (10 nM; 2 min) increases the extracellular levels of dopamine to approximately 400% of basal during the application in the nucleus accumbens^[2].
GBR 12935 dihydrochloride (100 μM; 60 min) increases extracellular levels of dopamine compared with levels for artificial cerebrospinal fluid (ACSF) by local perfusion for 60 min^[2].
GBR 12935 dihydrochloride (1-9 nM) dose-dependently inhibits active uptake of [³H]dopamine in homogenates of the nucleus accumbens^[2].
Co-perfusion of 100 μM GBR 12935 dihydrochloride with either 100 μM Sulpiride (HY-B1019) or Raclopride (HY-103414) produces a significant reduction in the GBR 12935 dihydrochloride induced increase in the extracellular levels of dopamine to basal levels^[2].

In Vivo

GBR 12935 dihydrochloride (1-32 mg/kg; repeat injection; 7 d) elevates locomotion activity to a greater extent in C57BL/6J mice than DBA/2J mice, and (10 mg/kg; injection; 7 d) results few mice sensitized to cocaine-induced stereotypy with repeated injections^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Adult male DBA/2J and C57BL/6J mice (22-30 g)^[3]
Dosage:	1.0, 3.2, 10, 32 mg/kg
Administration:	Repeat injection; for 7 days
Result:	Elevated locomotion activity to a greater extent in C57BL/6J mice than DBA/2J mice. No stereotypy was induced by an eighth day challenge of 10 mg/kg GBR 12935 dihydrochloride in mice pretreated with seven dally injections of either 32 mg/kg cocaine or saline.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.13 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.13 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (5.13 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
