产品描述

STF-083010 (formerly IRE1 Inhibitor I) is a novel and specific small-molecule inhibitor of IRE1α endonuclease. In many solid tumors and hematologic malignancies, including multiple myeloma (MM), the adaptive Ire1-XBP1 pathway has been found to be activated. Following endoplasmic reticulum stress in both vitro and vivo, STF-083010 reduced Ire1 endonuclease activity without affecting its kinase activity. In models of human MM xenografts, STF-083010 treatment demonstrated significant antimyeloma activity. STF-083010, in contrast to other similarly isolated cell populations, was preferentially toxic to freshly isolated human CD138(+) MM cells. The discovery of this new Ire1 inhibitor lends credence to the idea that the Ire1-XBP1 axis represents a promising target for anticancer therapy, particularly in the context of MM. STF-083010 exhibits dose- and time-dependent cytostatic and cytotoxic activity in MM.1S, MM.1R, and RPMI 8226 MM cell lines. STF-083010 blocks IRE1α's endonuclease activity without affecting its kinase activity in the MiaPaCa2, Panc0403, and SU8686 cell lines. It also inhibits the splicing of XBP1. After three days of culture, STF-083010 shows a 70% growth inhibition in Eμ-TCL1 CLL cells. STF-083010 inhibits 20% of growth in MEC1 and MEC2 cells within 48 hours. WaC3 cells react to STF-083010 treatments by gradually slowing their growth.

体内研究 (In Vivo)	STF-083010 (i.p., 30 mg/kg) significantly slows the growth of the tumor in a human multiple myeloma (MM) xenograft model. [1]
酶活实验	The presence of 32P-γATP controls the activity of autophosphorylation. By adding radiolabeled HAC1 508-nt RNA substrate that has been in vitro synthesized using 32P-UTP, endonuclease activity is assessed. Radiolabeled HAC1 508 nt RNA, recombinant hIRE1 protein, and the appropriate buffers are all added to STF083010. Electrophoresis of polyacrylamide gels is used to measure kinase activity. 32P-γATP or 32P-UTP autoradiography is used to quantify the products of RNA scleavage.
细胞实验	The following day, drug treatment was begun after 3000 cells were seeded in 96-well plates over night. The stop solution (4 mM HCl, 0.1% Nondet P40 in isopropanol), which is added to dissolve the MTT, is then added to the cells after 48 hours of incubation. MTT is added to the cells and cultured for 4 hours at 37°C. With a reference wavelength of 630 nm, a spectrophotometer reads the plates at 590 nm absorbance. Utilizing GraphPad Prism, IC50 values are computed.
动物实验	Mice: The right and left hind footpads of each BALB/c nude mouse (male, 5 weeks old) are subcutaneously inoculated with 5×106 HCT116 p53+/+ or HCT116 p53-/- cells. After four days, DMSO or STF-083010 (40 mg/kg) is injected intraperitoneally every three days. Every five days, tumors are measured, and their volumes are calculated using the formula mm3=(length (mm))×(width (mm))2/2).

Solubility in Formulation 1: ≥ 3.25 mg/mL (10.24 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 32.5 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL.

Solubility in Formulation 2: 2% DMSO+40%PEG 300+5% Tween80 +ddH2O: 2mg/mL

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
7、以上所有助溶剂都可在 Invivochem.cn网站购买。

1、根据实验需要选择合适的溶剂配制储备液 (母液)：对于大多数产品，InvivoChem推荐用DMSO配置母液 (比如：5、10、20mM或者10、20、50 mg/mL浓度），个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;

2、如果您找不到您想要的溶解度信息，或者很难将产品溶解在溶液中，请联系我们;

3、建议使用下列计算器进行相关计算（摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等）;

4、母液配好之后，将其分装到常规用量，并储存在-20°C或-80°C，尽量减少反复冻融循环。
