GBR 12935 dihydrochloride_product_DataBase

Bioactivity	GBR 12935 dihydrochloride is a potent, and selective dopamine reuptake inhibitor, with the binding constant (Kd) 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[1][2][3][4].
Invitro	GBR 12909 (10-100 nM) also shows a high affinity for CYP2D6 with the Kd 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]. Animal Model:
