213 results about "Hsp90 inhibitor" patented technology

An Hsp90 inhibitor is a substance that inhibits that activity of the Hsp90 heat shock protein. Since Hsp90 stabilizes a variety of proteins required for survival of cancer cells, these substances may have therapeutic benefit in the treatment of various types of malignancies. Furthermore, a number of Hsp90 inhibitors are currently undergoing clinical trials for a variety of cancers. Hsp90 inhibitors include the natural products geldanamycin and radicicol as well as semisynthetic derivatives 17-N-Allylamino-17-demethoxygeldanamycin (17AAG).

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.

Uses of labeled hsp90 inhibitors

The disclosure provides evidence that the abundance of this particular “oncogenic HSP90” species, which is not dictated by HSP90 expression alone, predicts for sensitivity to HSP90 inhibition therapy, and thus is a biomarker for HSP90 therapy. The disclosure also provides evidence that identifying and measuring the abundance of this oncogenic HSP90 species in tumors predicts of response to HSP90 therapy. “Oncogenic HSP90” is defined herein as the HSP90 fraction that represents a cell stress specific form of chaperone complex, that is expanded and constitutively maintained in the tumor cell context, and that may execute functions necessary to maintain the malignant phenotype. Such roles are not only to regulate the folding of overexpressed (i.e. HER2), mutated (i.e. mB-Raf) or chimeric proteins (i.e. Bcr-Abl), but also to facilitate scaffolding and complex formation of molecules involved in aberrantly activated signaling complexes (i.e. STATS, BCL6).

Methods for Sensitizing Cancer Cells to Inhibitors

The present invention is based on the discovery that inactivation of the heat shock response in cancer cells significantly enhances their sensitivity to proteasome and Hsp90 inhibitors. The inventors have discovered novel compounds which exhibit low toxicity, inhibit the heat shock protein response and sensitize cancer cells to anti-cancer therapies. In general, the heat shock protein inhibitors of the present invention share a common structure, namely a 2H-benzo[a]quinolizine tricyclic ring. Also encompassed are methods for a high throughput screen to identify heat shock inhibitors that sensitize cancer cells to anti-cancer therapies.
