44 results about "Topoisomerase-II Inhibitor" patented technology

Any substance that inhibits topoisomerase-II, a topoisomerase that relieves torsional stress in a DNA molecule by cutting both strands of the DNA double helix. A topoisomerase II inhibitor can either stabilize the DNA-protein complex or inhibit the catalytic activity of the enzyme. Inhibition of topoisomerase-II causes DNA damage, inhibition of DNA replication, and apoptosis.

Antitumor agent

The present invention relates to an antitumor agent containing a histone deacetylase inhibitor and a topoisomerase II inhibitor in combination. This combination has been found to exhibit a synergistic anticancer or antitumor effect compared to administration of either the histone deacetylase alone or the topoisomerase II inhibitor alone. Thus, this combination provides a tumor or cancer treatment with fewer side effects since a lower dosage of both ingedients may be administered.

Methods for enhancing the efficacy of cytotoxic agents through the use of HSP90 inhibitors

InactiveUS7211562B2Avoid or reduce their respective toxicity to patientsGrowth inhibitionHeavy metal active ingredientsPeptide/protein ingredientsBinding siteRadicicol
The administration of cytotoxic agents followed by the administration of heat shock protein 90 inhibitors, such as ansamycins, has a synergistic effect on the growth inhibition of cells. This synergy occurs at doses of each cytotoxic agent that normally only causes minimal growth inhibition of cells. Such combination therapy thus allows one to use lower doses of cytotoxic agents to avoid or reduce their respective toxicity to patients without compromising their growth inhibitory effects. Thus, these combinations can be used for the treatment of an animal, preferably a mammal, that has a cell proliferative disorder, whether the cells have wild-type Rb or are Rb deficient or Rb negative. One such method, directed to treating cell proliferative disorders includes the step of administering a therapeutic effective amount of a cytotoxic agent followed by administering a therapeutic effective amount of a heat shock protein 90 inhibitor. The cytotoxic agent may be a microtubule-affecting agent, topoisomerase II inhibitor, a platinum complex, paclitaxel, or a paclitaxel derivative. The HSP90 inhibitor may be an ansamycin, radicicol or a synthetic compound that binds to the ATP-binding site of HSP90.

Novel drug targets to overcome de novo drug-resistance in multiple myeloma

Topoisomerase II alpha (topo IIα) is exported from the cell nucleus in human myeloma cells by a chromosome-maintenance protein-1 (CRM1)-dependent mechanism, resulting in topo II inhibitor resistance. The nuclear export signal (NES) of topo IIα is unique, making it a potential target for small molecule inhibitors. Small molecules NES inhibitors were identified, which inhibited binding of topo IIα to the export receptor CRM1. Inhibition was specific to topo IIα as p53 trafficking was unaffected along with topo IIα protein expression and function (decatenation). These topo IIα-specific nuclear export inhibitors may potentially lead to a new approach in circumventing drug resistance in multiple myeloma. The compounds provide a protocol for treating multiple myeloma or an oncogenic disease. Further, the topoisomerase II nuclear export signal inhibitor may be combined with a topoisomerase II inhibitor.
