In vitro study | KW-2478 inhibits the binding of bRD to Hsp90α with IC50 of 3.8 nM. KW-2478 degradates the Hsp90 client proteins, including FGFR3 and IGF-1Rβand c-Raf-1. KW-2478 reduces the level of phosphorylated Erk1/2. KW-2478 induces apoptosis by cleavage of PARP, a substrate of caspase-3 In U266 cells,. KW-2478 has Time dependency of antiproliferative activity consecutive drug exposure for at least 12 hours is necessary to to exert potent antitumor activity. KW-2478 downregulates the translocation products of IgH locus. KW-2478 inhibits the transcription of c-Maf and cyclin D1 genes by mainly suppressing the function Cdk9. KW-2478 has potent and broad growth inhibitory activities against various cell lines, KW-2478 inhibites cancer cell growth in all cell lines, with EC50 of 101-252 nM, 81.4-91.4 nM and 120-622 nM for B- cell lymphoma, mantle cell lymphoma and multiple myeloma. KW-2478 also show pot growth activity in primary CLL and NHL cells with EC50 of 40-170 nM and 200-400 nM. No. KW-2478 inhibited the binding of bRD to Hsp90α with an IC50 of 3.8 nM. KW-2478 degrades Hsp90 receptor proteins, including FGFR3,IGF-1Rβ and c-Raf-1. KW-2478 decreased the level of phosphorylated Erk1/2. In U266 cells, KW-2478 induced apoptosis by cleavage of PARP, a substrate for caspase-3. KW-2478 has time-dependent anti-proliferative activity requiring continuous drug exposure for at least 12 hours to exert potent anti-tumor activity. KW-2478 down regulated the translocation product of IgH site. KW-2478 inhibits the transcription of c-Maf and cyclin D1 genes by mainly inhibiting the function of cdk9. KW-2478 has potent and extensive inhibitory activity against various cell lines, KW-2478 inhibits cancer cell growth in all cell lines, with EC50 of 101-252 nM for B- cell lymphoma, mantle cell lymphoma, and multiple myeloma, respectively, 81.4-91.4 nM and 120-622 nM.
