Corynantheidine is an alkaloid that has been found in M. speciosa (Kratom in Thai) and has antinociceptive activity.1,2 It is a partial agonist of the μ-opioid receptor that lacks β-arrestin recruitment activity.1 Corynantheidine selectively binds to μ-opioid receptors over κ- and δ-opioid receptors (Kis = 57.1, 385.4, and 172 nM, respectively, for the mouse receptors) and is selective for the μ-opioid receptor (EC50 = 104.24 nM) over the κ- and δ-opioid receptors, for which it has no activity, in [35S]GTPγS assays. It also binds to α1D- and α2A-adrenergic receptors and NMDA receptors (Kis = 41, 74, and 83 nM, respectively, for the human receptors), among others.1,2 Corynantheidine (10-100 nmol, i.c.v.) increases the latency to tail withdrawal in the tail-flick test in mice.1

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

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.
