名稱 | (E/Z)-BIX02188 |
描述 | BIX02188 is a specific MEK5 inhibitor (IC50: 4.3 nM), also inhibits ERK5 catalytic activity (IC50: 810 nM), and does not inhibit closely related kinases MEK1/2, JNK2, and ERK2. |
細(xì)胞實(shí)驗(yàn) | The cells are serum starved for 20 hours prior to stimulation with sorbitol at a final concentration of 0.4 M for 20 minutes at 37 °C. BIX02188 is added 1.5 hours prior to the addition of sorbitol. The cells are harvested and lysed in 50 μL RIPA buffer containing Halt protease and phosphate inhibitors at 4 °C for 5-10 minutes. The lysates are centrifuged for 10 minutes at 14,000 rpm and 50 μL lysate is added to 50 μl 2× sample buffer and boiled for 4 minutes at 95 °C. A 20 μl sample is run on SDS–PAGE 10% Tris-glycine gels and transferred to nitrocellulose. Western blotting is done with appropriate antibodies.(Only for Reference) |
激酶實(shí)驗(yàn) | Catalytic assay: MEK5 protein isolated from a baculovirus expression system is used to measure kinase activity utilizing PKLight ATP Detection Reagent. The assay is performed using 15 nM GST-MEK5 and 0.75 μM ATP in assay buffer consisting of 25 mM Hepes, pH 7.5, 10 mM MgCl2, 50 mM KCl, 0.2% BSA, 0.01% CHAPS, 100 μM Na3VO4, 0.5 mM DTT and 1% DMSO in the presence of varying concentrations of BIX02188. The kinase reaction mixture is incubated for 90 minutes at room temperature followed by addition of 10 μL of an ATP detection reagent for 15 minutes. The relative light unit (RLU) signal is measured and the RLU signals are converted to percent of control (POC) values for the determination of IC50 value. |
體外活性 | BIX02188顯著阻斷MEK5的催化活性,IC50值為4.3 nM,且抑制ERK5的催化活性,IC50值達(dá)0.83 μM。對于與之密切相關(guān)的激酶MEK1、MEK2、ERK1、p38α、JNK2、TGFβR1、EGFR和STK16則無活性,其中TGFβR1、p38α的IC50值分別為1.8 μM和3.9 μM,其他激酶的IC50值>6.3 μM。BIX02188預(yù)處理能以劑量依賴的方式抑制甘露醇誘導(dǎo)的HeLa細(xì)胞中ERK5的磷酸化,但對ERK1/2、p38和JNK1/2 MAPKs的磷酸化無抑制作用。單獨(dú)處理BIX02188 24小時(shí),對HeLa或HEK293細(xì)胞無細(xì)胞毒作用。BIX02188通過抑制MEK5/ERK5信號傳導(dǎo)途徑,抑制MEK5/ERK5/MEF2C驅(qū)動(dòng)的熒光素酶表達(dá)系統(tǒng)中MEF2C的轉(zhuǎn)錄激活,其IC50值在HeLa和HEK293細(xì)胞中分別為1.15 μM和0.82 μM。通過阻斷MEK5信號途徑,BIX02188還能以劑量依賴的方式抑制用300 μM Water2刺激的牛肺微血管內(nèi)皮細(xì)胞(BLMECs)中BMK1的磷酸化,IC50為0.8 μM。BIX02188完全逆轉(zhuǎn)了TNF介導(dǎo)的JNK激活的抑制效果,在BMK1抑制上有類似效應(yīng),表明它通過激活MEK5-BMK1信號途徑抑制TNF信號。 |
