PURPOSE 17-DMAG is a hydrophilic derivative of the molecular chaperone inhibitor 17-(allylamino)-17-demethoxygeldanamycin (17-AAG; NSC-330507), which is currently being evaluated for the treatment of cancer in clinical trials. 17-DMAG offers a potential advantage over 17-AAG because its aqueous solubility eliminates the need for complicated formulations(More)
PURPOSE Zebularine is a DNA methyltransferase inhibitor proposed for clinical evaluation. EXPERIMENTAL DESIGN We developed a liquid chromatography/mass spectrometry assay and did i.v. and oral studies in mice, rats, and rhesus monkeys. RESULTS In mice, plasma zebularine concentrations declined with terminal half-lives (t(1/2)) of 40 and 91 minutes after(More)
Integrating combinatorial lead optimization of [1,2]-diamine core structure based on ethambutol with high-throughput screening has led us to focus on three promising analogs (SQ37, SQ59 and SQ109) as potential anti-tubercular drug candidates from thousands of synthesized diamine analogs for further characterization of their biopharmaceutical and(More)
PURPOSE NSC 743400 is a novel synthetic indenoisoquinoline analog under development as an anticancer agent. It is a potent topoisomerase I inhibitor with potential therapeutic advantages over FDA-approved camptothecin derivatives. In preparation for clinical development of NSC 743400, we determined the pharmacokinetics after administration to rats and dogs.(More)
Non-clinical studies were conducted to evaluate the toxicity of Antalarmin, a corticotropin-releasing hormone type 1 receptor antagonist being developed for therapy of stress-related pathologies. Antalarmin was not genotoxic in bacterial mutagenesis assays, mammalian cell mutagenesis assays, or in vivo DNA damage assays. In a 14-day range-finding study in(More)
