SNX-5422

Study Description

Brief Summary: Heat shock protein 90 (Hsp90) is a chemical in the body that is involved in the promotion of cancer. SNX-5422 is an experimental drug that blocks Hsp90.

Detailed Description: Heat shock protein 90 (Hsp90) chaperone proteins stabilize many client proteins including mutant EGFR, and are also hypothesized to help maintain the malignant phenotype of mutant EGFR in lung adenocarcinoma. Treatment of EGFR mutant cell lines with the Hsp90 inhibitor geldanamycin results in cellular degradation, decreased levels of pAKT/cyclin D1, and increased apoptosis. Furthermore, Hsp90 inhibitors hamper growth of tumors in nude mice with gefitinib-resistant H1975-xenografts in vivo. Clinical data showed that mono-therapy with some Hsp90 inhibitors provides stable disease and some patients have partial remissions as best responses in heavily pre-treated non small cell lung cancer patients. SNX-5422 is a pro-drug of SNX-2112, a potent, highly selective, small-molecule inhibitor of the molecular chaperone Hsp90. Inhibitors of the chaperone protein Hsp90 are of current interest because of the central role that Hsp90 plays in the maturation and maintenance of numerous proteins, for example HER2 and mutated EGFR, that are critical for tumor cell viability and growth.
