Biological descriptionPartial agonist at α7nACh receptors. Binds selectively to α7 subunits, with no significant activity seen at α2, α3 and α4. (EC50 = 10 μM in vitro (striatal slices)). Shown to elicit nootropic, neuroprotective and anti-inflammatory effects.
Chemical name3-[(3E)-3-[(2,4-Dimethoxyphenyl)methylidene]-5,6-dihydro-4H-pyridin-2-yl]pyridine dihydrochloride
Storage instructionsStore at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 100 mM and in DMSO to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
