JDTic is a selective inhibitor of kappa opioid receptor with IC50 value of 0.02nM [1].

JDTic is one of the kappa opioid receptor selective antagonists. These antagonists are thought as potential pharmacotherapies for addiction, anxiety disorders, depression, psychosis disorders and obesity. Because of the unique structural feature of JDTic, it is more selective and potent for KOR activity than other KOR antagonists. JDTic is shown to block the antinociceptive response of nicotine in the tail-flick test with a dose-dependent manner. It (8 mg/kg) can also block the nicotine withdrawal signs in mice via effecting the expression of a CPA associated with nicotine withdrawal. Additionally, JDTic is also reported to decrease the number of somatic withdrawal signs in morphine-dependent rats [2,3].

General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. We do not recommend long-term storage for the solution, please use it up soon.


Cell experiment: [1]

Cell lines

HEK293 cells expressing KOPr-GFP

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

10 μM, 60 min


The compound was administered for 60 min before lysing the cells. And pJNK-ir intensities were examined by Western blot analysis. JDTic significantly increased phospho-JNK-ir at 10 μM.

Animal experiment: [2]

Animal models

Male Wistar rats

Dosage form

Intraperitoneal injection, 3, or 10 mg/kg at 1 ml/kg, dissolved in sterile water


Post-hoc analysis using Newman-Keuls test indicated a significant difference from baseline responding only in the JDTic 10 mg/kg pretreated group at the 2 h pretreatment time point (p=0.002). Furthermore, there was also a significant decrease observed in the 10 mg/kg JDTic treated group when compared to vehicle control at the 2 h time point, while the groups were virtually identical at later time points.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
