Background | It is a potent and selective GSK-3α/β inhibitor and a potent Wnt/β-catenin signaling pathway activator. |
Biological Activity | CHIR-99021是 GSK-3α/β 抑制剂, IC50 分别为 10 nM,6.7 nM。 抑制 GSK-3α/β 比同源物 CDC2 和 ERK2 高 500 倍[1-4]。 |
IC50 | GSK-3β:6.7nM;GSK-3α:10nM [1-4] |
In Vitro | CHIR 99021是一种小有机分子,通过竞争其ATP结合位点来抑制GSK3α和GSK3β。体外激酶检测显示CHIR 99021特异性抑制GSK3β(IC50 = ~5 nM)和GSK3α(IC50 = ~10 nM),对其他激酶的影响很小[2]。在CHIR-99021存在下,ES-D3细胞的存活率在2.5μM时降低24.7%,在5μM时降低56.3%,在7.5μM时降低61.9%,在10μMCHIR-99021时降低69.2%,IC50为4.9μM [3]。CHIR 99021抑制人GSK-3β,Ki值为9.8 nM [1]。 |
In Vivo | 在照射前4小时给予CHIR99021(2mg/kg)一次,在14.5Gy腹部照射(ABI)后显著提高存活率。 CHIR99021处理显著阻断了隐窝细胞凋亡和p-H2AX +细胞的积累,并改善了隐窝再生和绒毛高度。 CHIR99021治疗通过阻断细胞凋亡来增加Lgr5 +细胞存活率,并且有效地防止Olfm4,Lgr5和CD44的减少早在4小时[4]。在ZDF大鼠中,单次口服剂量的CHIR 99021(16mg/kg或48mg/kg)迅速降低血浆葡萄糖,给药后3-4小时最大降低近150mg/dl [1]。 |
Cell Experiment | 使用MTT测定法在暴露于不同浓度的GSK3抑制剂三天后测定小鼠ES细胞的存活力。 MTT活性的降低是一种可靠的基于代谢的测试,用于量化细胞活力;这种减少与细胞活力的丧失相关。将2,000个细胞在含有LIF的ES细胞培养基中的明胶包被的96孔板上接种过夜。第二天,将培养基更换为不含LIF且血清浓度降低的培养基,并补充0.1-1μMBIO,或1-10μMSB-216763,CHIR-99021或CHIR-98014。不含GSK3抑制剂或DMSO的基础培养基用作对照。所有测试条件一式三份进行分析[3]。 |
Animal Experiment | 大鼠[1]制备重量<140g的雄性Sprague Dawley大鼠的原代肝细胞,并在分离后1-3小时使用。将等份的1×10 6个细胞在1mL DMEM/F12培养基加0.2%BSA和CHIR 99021(口服16或48mg/kg)或对照中在12孔板中在低速振荡器上于37℃孵育30分钟。在富含CO 2的气氛中,通过离心收集并在缓冲液A加0.01%NP40中冷冻/解冻裂解;再次进行GS测定。小鼠[4]使用6-10周龄的小鼠。对C57BL/6背景(F10)和Lgr5-EGFP(Lgr5-EGFP-IRES-creERT2)小鼠的PUMA +/+和PUMA -/- 同窝小鼠进行全身照射(TBI)或腹部照射(ABI)。在放射前4小时腹膜内(ip)注射2mg/kg CHIR99021或在放射前28小时和1小时/ 1mg SB415286注射小鼠。处死小鼠以收集小肠用于组织学分析和蛋白质印迹。在处死前,所有小鼠腹膜内注射100mg/kg BrdU。 |
Kinase Experiment | 通过使用其His或Glu标签从SF9细胞中纯化激酶。纯化Glu标记的蛋白质,纯化His标记的蛋白质。激酶测定在96孔板中用适当的肽底物在300μL反应缓冲液中进行(50mM Tris-HCl,pH 7.5,10mM MgCl 2,1mM EGTA,1mM二硫苏糖醇,25mMβ-甘油磷酸盐,1mM的变化)NaF和0.01%牛血清白蛋白)。肽的Km值为1至100μM。将CHIR 99021或CHIR GSKIA加入3.5μLMe2SO中,然后加入ATP至终浓度为1μM。温育后,将三份100μL等分试样转移至含有100μL/孔50μMATP和20mM EDTA的Combiplate 8平板。 1小时后,用磷酸盐缓冲盐水冲洗孔5次,填充200μL闪烁液,密封,30分钟后在闪烁计数器中计数。所有步骤均为室温。抑制百分比计算为100×(抑制剂 - 无酶对照)/(Me2SO对照 - 无酶对照)[2]。 |
