The antifungal efficacy of voriconazole (VRC) differs among host species, with potent efficacy in humans but less in rodents. We investigated the possible involvement of pregnane X receptor (PXR) and constitutive androstane receptor (CAR) in the species-specific efficacy of VRC

The objective of the study was to establish an in vivo method for assessing cytochrome P450 3A (CYP3A) activity using therapeutically inert nanogram doses of midazolam. We administered four escalating single doses of oral midazolam (0.0001-3 mg) to 12 healthy participants

Ketoconazole binds to and antagonizes pregnane X receptor (PXR) activation. Yeast high throughput screens of PXR mutants define a unique region for ketoconazole binding. Ketoconazole genetically interacts with specific PXR surface residues. A yeast-based genetic method to discover novel nuclear

Cushing's syndrome is a rare disorder. The corticotropin (ACTH)-dependent form of this syndrome generally results either from excessive ACTH secretion by a pituitary adenoma or ectopic secretion by a malignant tumor. Theoretically, the latter type can be assumed to occur
