KW-2478 is a novel and potent nonansamycin inhibitor of heat shock protein 90 (Hsp90) to overcome the limitations, including low water solubility and hepatotoxicity, of 17-allylamino-17-demethoxygeldanamycin (17-AAG). KW-2478 exerts a strong antitumor activity against multiple myeloma (MM) cells with various chromosormal translocation, in which KW-2478 inhibits cell growth and apoptosis associated with Hsp90 client protein degradation and the decreasing of IgH translocation products including FGFR3, c-Maf and cyclin D1. Recent study results have revealed that KW-2478 is able to deplete Hsp90 client Cdk9 and the phosphorylated 4E-BP1, a transcriptional kinase and a transcription inhibitor respectively, leading to the reduced expression of c-Maf and cyclin D1.
