Curator's Comment: The description was created based on several sources, including https://clinicaltrials.gov/ct2/show/NCT01063907 | https://www.ncbi.nlm.nih.gov/pubmed/28873084 | https://clinicaltrials.gov/ct2/show/NCT00457782 | https://www.ncbi.nlm.nih.gov/pubmed/26695442

KW-2478 is a novel and potent non-ansamycin inhibitor of heat shock protein 90 designed 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 chromosomal translocations. KW-2478 inhibits cell growth and apoptosis associated with Hsp90 client protein degradation. 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 reduced expression of FGFR3, c-Maf, and cyclin D1. KW-2478 suppresses tumor growth and induces the degradation of client proteins in tumors in NCI-H929 s.c. inoculated model at doses of 100 mg/kg or more. KW-2478 reduces both serum M protein and MM tumor burden in the bone marrow in OPM-2/GFP i.v. inoculated mouse model at doses of 100 mg/kg.

In Vitro Use Guide

OPM-2/GFP and KMS-11 cells were used for activity evaluation. The cells were plated into 96-well plates and treated with KW-2478. After 72 hours of cultivation, cell viability was determined using Cell Proliferation Reagent WST-1 (Roche Diagnostics). WST reagent was added to the wells, followed by incubation for 4 hours at 37°C. After that, the absorbance at 450 nm with reference at 650 nm was measured with a microplate spectrophotometer.
