| Description | AZ20 is a potent and selective inhibitor of ATR kinase with IC50 value of 5 nM. | |||||
| Targets | ATR kinase | |||||
| IC50 | 5 nM | |||||
| Kinase experiment [1]: | |
ATR kinase assay | ATR for use in the in vitro enzyme assay was obtained from HeLa nuclear extract by immunoprecipitation with rabbit polyclonal antiserum raised to amino acids 400 ~ 480 of ATR contained in the following buffer: 25 mM HEPES (pH 7.4), 2 mM MgCl2, 250 mM NaCl, 0.5 mM EDTA, 0.1 mM Na3VO4, 10% v/v glycerol, and 0.01% v/v Tween 20. ATR-antibody complexes were isolated from nuclear extract by incubating with protein A-Sepharose beads for 1 hr and then through centrifugation to recover the beads. In the well of a 96-well plate, 10 μL ATR-containing Sepharose beads were incubated with 1 μg of substrate glutathione S-transferase-p53N66 in ATR assay buffer (50 mM HEPES (pH 7.4), 150 mM NaCl, 6 mM MgCl2, 4 mM MnCl2, 0.1 mM Na3VO4, 0.1 mM DTT, and 10% (v/v) glycerol) at 37°C in the presence or absence of inhibitor. After 10 mins with gentle shaking, ATP was added to a final concentration of 3 μM and the reaction continued at 37°C for an additional 1 hr. The reaction was stopped by addition of 100 μL of PBS, and the reaction was transferred to a white opaque glutathione coated 96-well plate and incubated overnight at 4°C. This plate was then washed with PBS/0.05% (v/v) Tween 20, blotted dry, and analyzed by a standard ELISA technique with a phosphoserine 15 p53 antibody. The detection of phosphorylated glutathione S-transferase?p53N66 substrate was performed in combination with a goat anti-mouse horseradish peroxidase-conjugated secondary antibody. Enhanced chemiluminescence solution was used to produce a signal, and chemiluminescent detection was carried out via a TopCount plate reader. The resulting calculated % enzyme activity was then used to determine the IC50 values for the compounds. |
| Cell experiment [1]: | |
Cell lines | BT-474 cells and HT29 colorectal adenocarcinoma cells |
Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reaction Conditions | 60 mins |
Applications | AZ20 inhibited pAKT T308 in BT-474 cells, and inhibited pATM Ser-1981 and pDNA-PK Ser-2056 in HT29 cells. In LoVo colorectal adenocarcinoma cells, AZ20 induced growth inhibition with the GI50 value of 0.20 μM. |
| Animal experiment [1]: | |
Animal models | Female nude mice bearing LoVo tumors |
Dosage form | 5 mg/kg twice daily and 50 mg/kg once daily; p.o. |
Applications | At the dose of 10 μM, AZ20 was found to inhibit the cytochrome 3A4-mediated metabolism of Midazolam by 50%. In a low dose rat PK study, it demonstrated that AZ20 has respectable bioavailability. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

AZ20 is a potent and selective inhibitor of ATR. AZ20 inhibits ATR immunoprecipitated from HeLa nuclear extracts with an IC50 value of 5 nM and ATR mediated phosphorylation of Chk1 in HT29 colorectal adenocarcinoma tumor cells with an IC50 value of 50 nM.ATR is an attractive new anticancer drug target whose inhibitors have potential as chemo- or radiation sensitizers or as monotherapy in tumors addicted to particular DNA-repair pathways.AZ20 is the first reported inhibitor of ATR protein kinase demonstrating tumor growth inhibition in vivo and is therefore a useful probe molecule to aid further investigation of ATR tumor biology. AZ20 potently inhibited the growth of LoVo colorectal adenocarcinoma tumor cells in vitro. In the mTOR (pAKT) cell assay, AZ20 weak inhibited recombinant mTOR enzyme activity. AZ20 shows good selectivity against all of the PI3K isoforms together with ATM and DNA-PK, and when tested in a large panel of kinases, AZ20 shows very high general kinase selectivity.Female nude mice bearing LoVo tumors were treated with AZ20 orally at a dose of 25 mg/kg twice daily or 50 mg/kg once daily for 13 days. AZ20 showed monotherapy in vivo antitumor efficacy in LoVo colorectal xenografts in nude mice.References:[1]. Foote KM, Blades K, Cronin A et al.

请问各位大神，做注射液中试时所用到磁力搅拌器需要资质吗？
加入溶液把搅拌子放在烧杯溶液中，将控温探头固定在橡胶夹头上，加热头插入至溶液中，不能影响到搅拌子，然后先插上仪器接插的电源插头，再接通电源打开电源调速开关，指标灯亮，即开始工作。
调速是由低速逐步调至高速，不允许高速档直接起动，以免搅拌子不同步，引起跳动。加热有开关控制，打开加热源开关，选择所需的温度，绿灯亮表明加热盘工作，红灯亮表明停止加热盘工作，此时进入恒温状态，不工作时应切断电源，为确保安全，使用时请接上地线．仪器应保持清洁干燥，严禁溶液进入机内，以免损坏机件防止剧烈震动．向左转|向右转
裂解液配方：
尿素7M
硫脲2M
CHAPS4%
二次水至20ml
使用前加DTT至65mM，tris至40mM，PMSF至1mM
上样液配方：
尿素8M
CHAPS2%
1%溴酚蓝0.002%
二次水至10ml
使用前加DTT至18mM，IPGbuffer至0.5%
由于都含有尿素，特别难溶解，好像含有尿素的温度不能超过37度，就在磁力搅拌器上一直搅着，发现过了一两个小时还没溶解，怎么回事么？中间还在34度左右水浴锅里水浴过，还是没溶解，溅在烧杯壁上的液体都已经结晶了。
有人碰到这样的问题么，很着急，急求帮助。
1.裂解液和上样液配方有无问题？
2.尿素怎么老不容，有没有什么方法加速其溶解？
本人想买一台制备胶体金的加热磁力搅拌器，大家帮忙推荐下什么品牌的较好，谢谢
鸣谢！
