產(chǎn)品描述: KW-2449是一種多靶點(diǎn)抑制劑,最有效作用于Flt3,IC50為6.6 nM,作用于Flt3, Bcr-Abl和Aurora A適度有效;對(duì)PDGFRβ, IGF-1R, EGFR沒有抑制效果。Phase 1 |
靶點(diǎn):
Apoptosis;FGFR;FLT;JAK;Bcr-Abl;Src;c-Kit;AuroraKinase |
體外研究:
KW-2449 shows growth inhibitory activities against FLT3/ITD-, FLT3/D835Y-, and wt-FLT3/FL-expressing 32D cells, MOLM-13 and MV4;11 with GI50 values of 0.024, 0.046, 0.014, 0.024, and 0.011 μM, respectively. KW-2449 suppresses the phosphorylations of FLT3 (P-FLT3) and its downstream molecule phospho-STAT5 (P-STAT5) in MOLM-13 cells in a dose-dependent manner. KW-2449 increases the percentage of cells in the G1 phase of the cell cycle and reciprocally reduced the percentage of cells in the S phase, resulting in the increase of apoptotic cell population. |
體內(nèi)研究:
KW-2449口服處理給藥MOLM-13移植瘤模型,處理14天,具有顯著的抗癌效果,這種作用存在劑量依賴性 |
細(xì)胞實(shí)驗(yàn):
Cell lines: MOLM-13和 RS4;11細(xì)胞 Concentrations: 33nM, 75nM, 0.1μM, 0.3μM ,0.15μM Incubation Time: 24, 48, 和72小時(shí) Method: 與KW-2449在37oC下溫育72小時(shí)后,通過3′-[1-(羰基苯胺)-3, 4-四氮唑]- 雙(4-甲氧基-6-硝基) 苯磺酸鈉水合物法測定細(xì)胞活力使用細(xì)胞增殖試劑盒 II測定存活細(xì)胞數(shù)。為了分析細(xì)胞周期,使用 KW-2449處理 MOLM-13 和 RS4; 11細(xì)胞。在37oC下溫育24,48,和72小時(shí)后,分析 DNA含量。使用KW-2449或Imatinib處理24小時(shí)后,分析K562, TCC-Y, 和 TCC/Ysr細(xì)胞周期分布 |
動(dòng)物實(shí)驗(yàn):
