A New, Potent 2-Nitroimidazole Nucleoside Hypoxic Cell Radiosensitizer, RP170

Darinaparsin: solid tumor hypoxic cytotoxin and radiosensitizer.

PURPOSE Hypoxia is an important characteristic of the solid tumor microenvironment and constitutes a barrier for effective radiotherapy. Here, we studied the effects of darinaparsin (an arsenic cytotoxin) on survival and radiosensitivity of tumor cells in vitro under normoxia and hypoxia and in vivo using xenograft models, compared to effects on normal tissues. EXPERIMENTAL DESIGN The cytotox...

Gold nanoparticles as a potent radiosensitizer in neutron therapy

The purpose of this study was to investigate the potential of gold nanoparticles as radiosensitizer for use in neutron therapy against hepatocellular carcinoma. The hepatocellular carcinoma cells lines Huh7 and HepG2 were irradiated with γ and neutron radiation in the presence or absence of gold nanoparticles. Effects were evaluated by transmission electron microscopy, cell survival, cell cycle...

synthesis and characterizing radiosensitizing effect of nitroimidazole derivatives and 5-fu in hypoxic ht-29 cell

sugar-hybrid hypoxic cell radiosensitizer TX-2244, new hypoxia-targeting indoleamine 2,3-dioxygenase (IDO) inhibitors, and a hypoxia-targeting BNCT agent, BSH (sodium borocaptate-10B)-hypoxic cytotoxin tirapazamine

We describe herein for the first time our medicinal electronomics bricolage design of hypoxiatargeting antineoplastic drugs and boron tracedrugs as newly emerging drug classes. A new area of antineoplastic drugs and treatments has recently focused on neoplastic cells of the tumor environment/microenvironment involving accessory cells. This tumor hypoxic environment is now considered as a major ...
