Application of topoisomerase assays in the evaluation of natural products as antitumor agents
(1999)Initially, DNA topoisomerase (topo) inhibitors found clinical applications as antibiotics and cancer chemotherapeutic agents. Recently, we demonstrated that plant flavonoids that inhibit mammalian topo I or topo II might ...

Comparison of Two Different Doses of Ondansetron plus Dexamethasone in the Prophylaxis of Cisplatin-lnduced Emesis
(1997)This study was conducted to evaluate the efficacy of two different doses of ondansetron (8 mg vs. 24 mg) plus dexamethasone in the prevention of cisplatin (CDDP)-induced emesis and nausea (acute and delayed). The persistence ...

Flavonoids as DNA topoisomerase antagonists and poisons: Structure-activity relationships
(1995)Selected flavonoids were tested for their ability to inhibit the catalytic activity of DNA topoisomerase (topo) I and II. Myricetin, quercetin, fisetin, and morin were found to inhibit both enzymes, while phloretin, ...

Genistein inactivates bcl-2, delays the G2/M phase of the cell cycle, and induces apoptosis of human breast adenocarcinoma MCF-7 cells
(1998)The aim of this study was to identify the molecular mechanism of action of the isoflavone, genistein. Genistein at 0.15 mM caused MCF-7 apoptotic cell death, which was accompanied by cell cycle delay in the G2/M phase. ...

Pirfenidone normalizes the tumor microenvironment to improve chemotherapy
(2017)Normalization of the tumor microenvironment by selectively targeting components of the tumor extracellular matrix has been recently proposed to have the potential to decompress tumor blood vessels, increase vessel perfusion ...

Towards Optimal Design of Cancer Nanomedicines: Multi-stage Nanoparticles for the Treatment of Solid Tumors
(2015)Conventional drug delivery systems for solid tumors are composed of a nano-carrier that releases its therapeutic load. These two-stage nanoparticles utilize the enhanced permeability and retention (EPR) effect to enable ...
