TG-101348也顯著抑制JAK2 V617F, Flt3和Ret,IC50分別為3 nM, 15 nM和48 nM。TG101348對密切相關的JAK3的IC50高300倍以上,對JAK1和TYK2家族抑制效果不強。TG101348抑制有JAK2V617F突變的人紅細胞白血病細胞系,以及一種表達人JAK2V617F(的Ba/F3 JAK2V617F)鼠前B細胞系的增殖,IC50分別是305 nM 和270 nM。G-101348也抑制親本Ba/F3細胞的增殖至一般水平,IC50約為420 nM。TG101348降低STAT5磷酸化的濃度和抑制細胞增殖所需的濃度一致。TG101348以劑量依賴的方式誘導HEL和JAK2V617F Ba/F3細胞的凋亡。TG101348在濃度高達10 μM時對正常人真皮成纖維細胞沒有促凋亡活性。[1] TG101348降低GATA-1的表達,這和erythroid-skewing JAK2V617F+祖細胞分化有關,并且抑制STAT5和GATA S310的磷酸化。[2] TG101348抑制HMC-1.1(KITV560G)細胞的增殖,活性低于HMC-1.2 (KITD816V, KITV560G)細胞,IC50分別為740 nM和407 nM。[3]

激酶實驗 無細胞激酶活性測定
TG101348 的IC 50值使用Invitrogen公司的223激酶試劑盒測定,其中包括JAK2和JAK2V617F,或者Carna Biosciences的所有Janus激酶家族成員試劑盒,包括JAK1和TYK2。ATP濃度設定為激酶的Km值。

方法

約2×103細胞接種到微量滴定板的孔中,加入含指定濃度抑制劑的100μLRPMI-1640培養(yǎng)基。TG101348溫育72小時,50 μL XTT染料加入到每個孔中并孵育4小時,在CO2培養(yǎng)箱中培養(yǎng)。有色甲臜產(chǎn)物用分光光度法在450nm處測定在650nm處校正。50%的抑制作用(IC50)的濃度用GraphPad Prism 4.0軟件確定。所有的實驗都重復3次,并且結(jié)果和未處理的細胞的生長做比較。EpoBa/F3 JAK2V617F,Ba/F3p210,HEL和K562細胞凋亡是用DMSO和TG101348濃度的增加誘導來確定。
