Vincristine (VCR) is a mainstay of treatment of hematologic malignancies and solid tumors due to its well-defined mechanism of action, demonstrated anticancer activity and its ability to be combined with other agents. VCR is an M-phase cell cycle-specific anticancer drug with activity that is concentration and exposure duration dependent. The(More)
PURPOSE Voreloxin, a novel replication-dependent DNA-damaging agent, intercalates DNA and inhibits topoisomerase II. Voreloxin induces site-selective DNA double-strand breaks and apoptosis. We report the phase 1 experience of voreloxin in patients with relapsed/refractory solid tumors, including dose-limiting toxicity (DLT), maximum-tolerated dose (MTD),(More)
MAIN PURPOSE Voreloxin is a first-in-class anticancer quinolone derivative that intercalates DNA and inhibits topoisomerase II, inducing site-selective DNA damage. Voreloxin is in clinical studies, as a single agent and in combination with cytarabine, for the treatment of acute myeloid leukemia (AML). The preclinical studies reported here were performed to(More)
Following I.V. injection of 3H-aldosterone, the rates of clearance of plasma 3H-radioactivity was demonstrated to be sex-dependent in intact rats. Even though the percentages of CH2Cl2-extractable plasma radioactivity are greater in female than in male rats, the quantities of CH2Cl2-extractable label are similar until 60 min post-injection. However, the(More)
We have been shown in rats that the hepatic expression of the phosphatidylcholine translocase Mdr2 is induced by statins, inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase. Statins are known to activate sterol regulatory element-binding proteins (SREBPs), transcription factors that control key enzymes of the cholesterol and fatty acid(More)
