生物活性

STF-31 is a selective inhibitor of glucose transporter 1 (GLUT1), with an IC50 of 1 μM. STF-31 is also a NAMPT inhibitor. STF-31 inhibits glucose uptake in renal cell carcinoma (RCC) 4 cells.

GLUT1

1 μM (IC50)

体外研究(In Vitro)

STF-31 (0.01-10 μM; 10 days) is specifically toxic to RCC4 cells, whereas RCC4/VHL cells are relatively unaffected. RCC4/VHL cells treated with STF-31 (5 μM; 10 days) largely recovery, whereas RCC4 cells under the same conditions does not.
STF-31 (1.25-5 μM; 3 days) does not induce autophagy, apoptosis, or DNA damage. STF-31 causes a necrotic cell death.
STF-31 reduces the efferocytosis of wild type and SLC2A1-overexpressing LR73 cells.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay

Cell Line: Wild-type RCC4 cells (RCC4/VHL) and RCC4 cells without VHL
Concentration: 0.01, 0.1, 1, 10 μM
Incubation Time: 10 days
Result: Reduced viability of RCC4 cells without VHL in a concentration-dependent manner when compared to their wild-type counterparts.
体内研究(In Vivo)

STF-31 (10 mg/kg; i.p.; twice daily for 2 days, followed by once daily for another 3 days) does not affect normal mice body weight, behavior, and ERG responses. STF-31 reduces light-induced CX3CR1 mice microglial activation and retinal degeneration.
STF-31 (10 mg/kg; i.p.) promotes accumulation of necrotic thymocytes after Dexamethasone-induced apoptosis in vivo.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Twelve-week old C57BL/6J and CX3CR1 mice
Dosage: 10 mg/kg
Administration: I.p. injections; twice daily for 2 days, followed by once daily for another 3 days
Result: Improved photoreceptor survival and reduced microglial activation of CX3CR1 mice, and not induced any C57BL/6J mice retinal cell death.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
