VWK147
VWK147 is a second-generation HSP90 C-terminal domain (CTD) inhibitor. VWK147 targets the CTD dimerization interface, prevents HSP90 CTD dimerization, disrupts co-chaperone PPID binding to HSP90 CTD, and inhibits HSP90 chaperone function dependent on dimerization. VWK147 reduces protein levels of HSP90 client proteins ULK1, RIPK1, and CDK4 without inducing a heat shock response. VWK147 induces cell death, including apoptosis, in Cisplatin (HY-17394)-sensitive and -resistant urothelial carcinoma cells. VWK147 induces LC3-II accumulation, inhibits autophagosome-lysosome fusion to block canonical autophagy, and induces non-canonical LC3 lipidation independent of ULK1 and PIK3C3 complexes. VWK147 can be used for the research of urothelial carcinoma.

VWK147 inhibits the interaction between HSP90β CTD and PPID in a TR-FRET assay[1].
VWK147 (10 μM; 3 h) does not bind to the HSP90 NTD in a fluorescence polarization assay[1].
VWK147 (25-100 μM; 1 h) inhibits HSP90 chaperone function in a cell-free luciferase refolding assay[1].
VWK147 (2-50 μM; 1 h) reduces HSP90α CTD dimers in a BS3 crosslinker assay[1].
VWK147 (1-10 μM; 6 h) destabilizes HSP90 client proteins ULK1, RIPK1, and CDK4 in Cisplatin-sensitive T24 and Cisplatin-resistant T24-CR urothelial carcinoma cells[1].
VWK147 (0.1-100 μM; 72 h) reduces cell viability in Cisplatin-sensitive (253J, T24) and -resistant (253J-CR, T24-CR) urothelial carcinoma cells with IC50 values of ~3-5 μM after 72 h[1].
VWK147 (10 μM; 0-24 h) induces cell death with both apoptotic and necrotic properties in T24 and T24-CR urothelial carcinoma cells over 24 h[1].
VWK147 (5 μM; 24 h) induced cell death in 253J, 253J-CR, T24, and T24-CR urothelial carcinoma cells is partially caspase-dependent[1].
VWK147 (1-10 μM; 6 h) induces concentration-dependent PARP1 cleavage in T24 and T24-CR urothelial carcinoma cells[1].
VWK147 (5 μM; 1-24 h) induces time-dependent PARP1 cleavage in T24 and T24-CR urothelial carcinoma cells over 24 h[1].
VWK147 (5 μM; 0-24 h) induces caspase-3 activation in Cisplatin-sensitive (253J, T24) and -resistant (253J-CR, T24-CR) urothelial carcinoma cells over 24 h[1].
VWK147 (5 μM; 6 h) inhibits autophagic flux in T24 and T24-CR urothelial carcinoma cells, as shown by LC3-II accumulation[1].
VWK147 (5 μM; 4 h) inhibits autophagosome-lysosome fusion in T24 and T24-CR urothelial carcinoma cells stably expressing mRFP-EGFP-rLC3[1].
