Application

Thioridazine hydrochloride has been used as an intercalating agent for analyzing the integrity of double-stranded DNA (dsDNA) using square-wave voltammetry (SWV) techniques. Thioridazine hydrochloride has also been used as a positive control for the inhibition of hepatic enzyme cytochrome P4502D6 (CYP2D6) in human liver microsomes.

Biochem/physiol Actions

D2 dopamine receptor antagonist; phenothazine antipsychotic with reduced extrapyramidal side effects; Ca2+ channel blocker.

Preparation Note

250 mg of thioridazine hydrochloride is soluble in 5 ml of water and yields a clear, colorless to faint yellow solution. Thioridazine hydrochloride is also soluble in methanol, ethanol, and chloroform, but it is insoluble in ether.

The rise in antimicrobial resistance is a major global concern and requires new treatment strategies. The use of helper compounds, such as thioridazine (TDZ), an antipsychotic drug, in combination with traditional antibiotics must be investigated. The aim of this study

We have shown that heat shock proteins (HSPs) associated with steroid receptor complexes are involved in the activation of calcineurin by aldosterone and dexamethasone. To determine whether HSPs directly interact with calcineurin, we measured the effect of HSPs 90, 70

The ability of antipsychotic drugs to inhibit the catalytic activity of five cytochrome P-450 (CYP) isoforms was compared using in vitro human liver microsomal preparations to evaluate the relative potential of these drugs to inhibit drug metabolism. The apparent kinetic

Inhibition of human cytochrome P4502D6 (CYP2D6)-catalysed metabolism can lead to clinically significant alterations in pharmacokinetics. Since there is evidence that the selective serotonin reuptake inhibitor (SSRI) class of antidepressant drugs might inhibit CYP2D6, the effects of five SSRIs on human

We studied here, in NIH-3T3 fibroblasts, the effect of the Ca(2+)-ionophore A23187 (which is known to increase intracellular-free Ca(2+)) on the control of glycolysis and cell viability and the action of calmodulin antagonists. Time-response studies with Ca(2+)-ionophore A23187 have revealed
