KW-2478是一种新型、强效的非Ansamycin热休克蛋白90(Hsp90)抑制剂,可以克服17-烯丙胺基-17-脱甲基格尔德霉素(17-AAG)低水溶性和肝毒性的不足。KW-2478对各种染色体易位的多发性骨髓瘤(MM)细胞具有很强的抗肿瘤活性,其中,KW-2478抑制与Hsp90受体蛋白降解和IgH易位产物(包括FGFR3,c-Maf和cyclin D1)减少相关的细胞生长与凋亡。最近的研究结果表明,KW-2478能够耗尽Hsp90受体蛋白Cdk9(一种转录激酶)和磷酸化4E-BP1(一种转录抑制剂),从而下调c-Maf和cyclin D1的表达。
Information
KW-2478 KW-2478 is a nonansamycin HSP90 inhibitor with IC50 of 3.8 nM. Phase 1.
In vitro
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 of 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, respectively. KW-2478 also shows potent growth inhibitory activity in primary CLL and NHL cells with EC50 of 40-170 nM and 200-400 nM, respectively. .
In vivo
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.
