Thioridazine (Th), which is therapeutically used in psychiatric patients, was found to possess conspicuous antimicrobial activity when tested against 316 strains belonging to a number of Gram positive and Gram negative bacteria. Although Staphylococcus aureus, Vibrio chloerae and V. parahaemolyticus were found to be most sensitive, Th was highly bactericidal against S. aureus and bacteriostatic...

OBJECTIVE Human α1-acid glycoprotein has genetic variants, the F1, S, and A variants, which can be separated isoelectrophoretically. These variants show differences in their affinity of binding to several drugs. In this study, we investigated the factors determining drug binding to these α1-acid glycoprotein genetic variants using disopyramide, warfarin, and tamsulosin as marker compounds. ME...

The stability of 30 common antipsychotics (APs) in spiked whole blood was investigated over ten weeks in a preliminary experiment (designated "P experiment"). Pools of blank blood spiked with drugs at two different therapeutic levels were stored at four different temperatures: 20 °C, 4 °C, -20 °C, and -60 °C and extracted once weekly in duplicate, using a previously published method. A loss of ...

This in vitro study focuses on the UVA-induced reactions with DNA of thioridazine (TRZ), and two of its major metabolites (TRZ-2-sulfoxide or mesoridazine, MRZ; and TRZ-2-sulfone or sulforidazine, SRZ). TRZ binds covalently to DNA upon UVA-irradiation. Under comparable irradiation conditions, MRZ binds to a lesser extent and almost no binding was observed with SRZ. Besides, photo-induced geneti...
