Protocol

Animal experiment:

Rats[1]Voiding is studied in urethane-anesthetized (1.2 g/kg sc) or awake female Sprague-Dawley rats (250-300 g). In all experiments, control cystometrograms (CMGs) are recorded for ~2 h before intracerebroventricular and intravenous injection of vehicle or (±)-Epibatidine solutions. Dose-response curves are constructed by administering increasing doses of (±)-Epibatidine [0.001-1 μg in 1 μL intracerebroventricularly (icv); 0.001-1 μg in 200 μL iv] at 30-min to 2-h intervals. (±)-Epibatidine is administered ~30 min after vehicle (aCSF, 1 μL icv; or saline solution, 200 μL iv). Chlorisondamine (10 μg, 1 μL icv) is injected 10-30 min before (±)-Epibatidine via the intracerebroventricular route in some experiments to block the effect of the agonist. The intravesical pressure to induce micturition (PT), MVP, and intercontraction interval (ICI; the interval between voids or reflex bladder contractions) are measured and converted into percent change from control values[1].

Background

(+)-AJ 76 hydrochloride is an antagonist of dopamine autoreceptor with pKi values of 6.95, 6.67, 6.37, 6.21 and 6.07 for hD3, hD4, hD2S, hD2L and rD2 receptors, respectively.

Dopamine receptor is a G protein-coupled receptor and mainly exists in the vertebrate central nervous system (CNS). Dopamine receptor is a receptor for dopamine and plays a critical role in memory, learning, pleasure, cognition, motivation and fine motor control.

(+)-AJ 76 hydrochloride is a dopamine receptor antagonist. In rats, AJ76 stimulated locomotor activity and increased the levels of 3,4-dihydroxyphenylacetic acid (DOPAC) and HVA in brain, which were dopamine metabolites [1]. In rats injected with cocaine, (+)-A J76 increased the locomotor stimulation during the first 30 min. However, (+)-AJ76 inhibited the later more intense locomotor stimulation and cocaine-induced stereotypies [2]. In vivo, (+)-AJ76 induced dopamine release mainly through interaction with dopamine receptors in the terminal regions of the A9 and A10 dopaminergic fibers. However, (+)-AJ76 increased the level of DOPAC via the somatodendritic autoreceptors [3].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
