Background

(±)-U-50488 hydrochloride is a selective agonist for κ-opioid receptor [1].

The κ-opioid receptor (KOR) is a type of opioid receptor for opioid peptide dynorphin and controls addiction. Also, KOR plays an important role in stress, anxiety, anhedonia, depression and increased drug-seeking behavior.

(±)-U-50488 hydrochloride is a selective KOR agonist [1]. In isolated rat DRG neurons, U-50488 (0.3-40 μM) inhibited voltage-independent Ca2+ channel currents. In HeLa cells that didn’t express KOR, U-50488 (20 μM) blocked Ca2+ channels [2].

In rhesus monkeys, U-50488 exhibited potent antinociceptive activity and produced diuresis [1]. U-50488 enhanced contraction of the rabbit vas deferens induced by electrically with IC50 value of 26.5 nM. In mice, U-50488 impaired motor function with ED50 value of 15.3 mg/kg and reduced spontaneous activity [3]. In adult rats, U-50488 increased the threshold required to maintain self-stimulation responding, a depressive-like effect. While, males were significantly more sensitive than females to the threshold-increasing effects [4].

Calculation results:

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
