Sigma 2 Receptor 0.43 nM (Ki) |
CM398 protects the retinal pigment epithelial cell line ARPE-19 against paraquat-induced cytotoxic damage[1].
CM398 exhibits highly selective sub-nanomolar binding affinity (Ki = 0.43 nM) for sigma-2 receptors in rat brain homogenates, shows over 1000-fold selectivity over sigma-1 receptors, and has extremely low affinity for most non-sigma neurotransmitter receptors and transporters[3].
CM398 undergoes rapid phase I metabolism in rat liver microsomes, with an elimination half-life of 0.10 h[3].
CM398 (1-10 μM; 30 min) binds highly to rat plasma proteins, with an average binding rate of 93.8%[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CM398 (3-45 mg/kg; i.p.; single administration) produces dose-dependent analgesic effects in the mouse acetic acid writhing visceral pain model, with an i.p. ED50 of 14.7 mg/kg[2].
CM398 (0.01-30 mg/kg; intraperitoneal injection; single administration) exerts potent, dose-dependent analgesic effects in the mouse formalin inflammatory pain model, with an ED50 of 0.86 mg/kg[2].
CM398 (30 mg/kg; i.p.; single administration) exerts no significant analgesic effect in the acute thermal pain model of mouse tail-flick test at 55°C[2].
CM398 (i.p.; single administration at doses of 10-45 mg/kg) produces time- and dose-dependent anti-allodynic effects in the mouse CCI neuropathic pain model. The efficacy of i.p. doses of 30 mg/kg and 45 mg/kg is comparable to that of gabapentin, and the duration of action is longer than that of CM-304[2].
CM398 (i.p.; single administration, dose range 0.23-23.2 μmol/kg) exerts significant dose-dependent analgesic effects in mouse models of inflammatory pain, with statistically significant reductions in paw-licking duration observed at doses of 2.32 μmol/kg and 23.2 μmol/kg[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
