bis(7)-Tacrine is an AChE inhibitor.
Acetylcholinesterase ( AChE), the primary cholinesterase in the body, is an enzyme catalyzing the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.
In vitro: bis(7)-Tacrine, the 9-amino-1,2,3,4-tetrahydroacridine (THA) dimer, was identified as a promising drug candidate for the palliative treatment of Alzheimer's disease, due to its significant enhancement in acetylcholinesterase (AChE) inhibition potency and AChE/butyrylcholinesterase (BChE) selectivity relative to THA itself. Enzyme kinetic studies performed in rat cortex found that both bis(7)-tacrine and THA exhibited mixed inhibition, and the rat cortex KI values were consistent with the previously determined human cerebellum Ki values [1].
In vivo: Previous study evaluated the neuropharmacological effects of THA on memory impairment caused by scopolamine injection. BALB/c mice were orally treated with THA at 10 mg/kg for 10 days. Results showed that THA significantly could reduce the total number of entry error and reference memory errors. In addition, THA also inhibited the AChE activity in the hippocampus significantly [2].
Clinical trial: So far, no clinical study has been conducted.

| 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. |
