Tacrine hydrochloride hydrate

Synonyms: Tacrine, Tetrahydroaminacrine, Tetrahydroaminoacridine

Tacrine (Tetrahydroaminacrine, Tetrahydroaminoacridine) is a centerally active cholinesterase inhibitor that has been used to counter the effects of muscle relaxants, as a respiratory stimulant, and in the treatment of Alzheimer's disease and other central nervous system disorders. It also acts as a histamine N-methyltransferase inhibitor.

Biological Activity

Description Tacrine (Tetrahydroaminacrine, Tetrahydroaminoacridine) is a centerally active cholinesterase inhibitor that has been used to counter the effects of muscle relaxants, as a respiratory stimulant, and in the treatment of Alzheimer's disease and other central nervous system disorders. It also acts as a histamine N-methyltransferase inhibitor.
Targets
HNMT [3] cholinesterase [1]
In vitro
In vitro Tacirne is an active cholinesterase inhibitor that blocks the degradation of cholinergic nerves in the cerebral cortex and hippocampus to increase cholinergic transmission. Tacrine induces hepatic damages in vitro. It can also induce oxidative stress and mitochondrial dysfunction. Tacrine treatment in HepG2 cells markedly inhibits the phosphorylation of GSK3β[1].
Cell Research Cell lines HepG2 cells
Concentrations 300 μM
Incubation Time 5 h
Method

The level of H2O2 generation was monitored in HepG2 cells by adding the DCFH-DA. After treatment of 10–100 µM LQ for 12 h prior to the addition of 300 µM tacrine for 5h, cells were stained with 50 µM DCFH-DA for 1 h. DCFH oxidation was determined at excitation and emission wavelengths of 485 and 530 nm using a microplate reader.
In Vivo
In vivo In rats, tacrine increased markers of liver damages (ALT and AST), degenerative region areas, and numbers of infiltrating inflammatory cells. Tacrine is known to induce hepatocyte necrosis and degeneration[1]. In the past, tacrine was used for the treatment of cognitive dysfunction during vascular dementia and Alzheimer disease. It is found to abolish lipopolysaccharide induced inflammation including IL-6 secretion in the central nervous system. Tacrine can aggravate the progress of tularemia in a mouse model--the effect would be beneficial in several pathologies such as neurodegenerative disorders; e.g. the positive effect of tacrine when used in therapy for Alzheimer's disease would be attributed to its anti-inflammatory action in addition to any improvement in cognitive functions[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
