| Description | SC144 is an inhibitor of gp130 with IC50 values of 0.43 μmol/L and 0.88 μmol/L in NCI/ADR-RES and HEY cell lines, respectively | |||||
| Targets | gp130 | |||||
| IC50 | ||||||
| Kinase experiment [1]: | |
Binding assays | OVCAR-8 cells were lysed using M-PER supplemented with protease and phosphatase inhibitors. The supernatant of cell lysate containing 4 to 6 μg/μL total proteins was incubated with SC144 at indicated concentrations (0, 1, 10, 100, 1000 μmol/L) at room temperature for 1 hr, followed by proteolysis with 1 μg pronase to every 9,600 μg of lysate for 30 mins at room temperature. Final concentration of DMSO was 1% in all samples. To stop proteolysis, 5 × SDS sample loading buffer [Tris-HCl 0.25 mol/L, pH 6.8, SDS 10%, glycerol 50%, bromophenol blue 0.5%, dithiothreitol (DTT) 100 mmol/L] was added to each sample at a 1:4 ratio, mixed well, and boiled at 100℃ for 5 mins. Samples were analyzed by Western blotting. |
| Cell experiment [1]: | |
Cell lines | OVCAR-8, OVCAR-5, OVCAR-3, Caov-3, SKOV-3, HEY and NCI/ADR-RES |
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 | ~ 10 μM; 96 hrs |
Applications | SC144 treatment in vitro induced gp130 phosphorylation and deglycosylation, resulting in the downregulation of surface-bound gp130 and the abrogation of gp130-associated Stat3 activation. In addition, SC144 selectively inhibited the downstream signaling activation induced by gp130 substrates, including IL-6 and LIF. In OVCAR-8 cells, protein expression regulated by the gp130/Stat3 axis was also down-regulated after SC144 treatment, including Bcl-2, Bcl-XL, survivin, cyclin D1, MMP-7, gp130 and Ape1/Rel-1. |
| Animal experiment [1]: | |
Animal models | OVCAR-8 xenograft mouse model |
Dosage form | 10 mg/kg; i.p. or p.o.; q.d. |
Applications | In a mouse xenograft model of human ovarian cancer, SC144 significantly inhibited tumor growth. After the exposure to SC144 for 2 months, gp130, Bcl-2, Bcl-XL, MMP-7 and Ape1/Ref-1 protein levels were substantially decreased in the tumor site in the treatment group compared with the control group. |
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. |

SC144 is an inhibitor of gp130 with IC50 values of 0.43 μmol/L and 0.88 μmol/L in NCI/ADR-RES and HEY cell lines, respectively [1].
SC144 is a first-in-class small-molecule gp130 inhibitor with oral activity in ovarian cancer. It can substantially increase the phosphorylation of gp130 (S782) in both OVCAR-8 and Caov-3 cells in a time- and dose-dependent manner. The increase phosphorylation then suppresses Stat3 signaling pathway since the constitutive Stat3 activation is maintained by extracellular gp130 ligands, Besides that, SC144 also causes substantial cell apoptosis in these cells. [1].
Apart from the effect on gp130, it has been reported that SC144 can directly bind and stabilize IL-24 in cancer cells. Additionally, SC144 has shown to have effects on cell cycle perturbation and apoptosis induction [2].
SC144 may also have other cellular protein targets, resulting in multiple potential molecular mechanisms. SC144’s anticancer potency may be a sum of these effects [2].

这样的回答可能没分，好和不好都是比较出来的，一群国产的放在一起比总有个性能比较均衡，比较突出性价比好的，
还是没有和说那个厂家的好桂林的呢好像是优利特这个厂家在做，特康的前身呢就是百特，现在的百特呢基本上是在做试剂，这些东西呢。
也搜索的到的，不过答案还是比较接近的，但想知道的是国产那个厂家生产的比较好，而只回答了一半就和介绍了下国产的血球分析仪有那个几个大的厂家，没有和区分那个最好那个第二那个次点，或许一堆鸡蛋里实在挑不出骨头。
具所知呢迈瑞的好点特康实力没有迈瑞好，迈瑞吸引了一批外资在搞研发，桂林的呢好像有个优利特现在出血分析仪，他做的尿分析仪市场的占有还可以，血的反应不是很强烈。
实在是想找个内行的给比较下。
以前用countstar,一块计数板5个孔，后来实验室又换了biorad的TC20，一块板子两个孔，只能计两个数，一盒板子30片500块，价格越来越贵。这样我一个12孔板计个数就要花百来块钱啊。大家都是这么用的？板子是塑料的，有没有什么可以清洗之后重复利用的方法？
