生物活性

BT44 is a selective RET activator. BT44 can penetrate through the blood-brain barrier and can be used for the research of neurodegenerative disorders and diabetes mellitus[1][2].

体外研究
(In Vitro)

BT44 (7.5-75 μM; 15 min) 促进 RET 磷酸化并选择性激活表达 GFL 受体的细胞的下游级联反应[1]
BT44 (0.5-10 μM; 16-20 h) 促进感觉神经元的神经突生长[1]

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

Western Blot Analysis[1]

Cell Line: GFRα3-transfected MG87RET cells
Concentration: 7.5, 18, 35 and 75 μM
Incubation Time: 15 min
Result: Increased RET and ERK phosphorylation.
体内研究
(In Vivo)

BT44 (5-25 mg/kg; s.c.; every second day for 10, 42 or 14 days) 在神经性的 SNL 和 STZ 模型中可减轻感觉体征[1]
BT44 (12.5 or 25 mg/kg; s.c.; every second day for 10 days) 对实验性神经病变动物 DRGs 中 IB4 阳性神经元有保护作用[1]
BT44 (0.1 and 0.3 μg/24 h; infuse into the right dorsal striatum for 14 days) 在 6-OHDA 帕金森大鼠模型中逆转 amphetamine 引起的运动失衡,似乎保护纹状体中的多巴胺能纤维[2]
BT44 (10 mg/kg; i.v.) 穿过血脑屏障,在大鼠中迅速从循环 (半衰期 (t1/2) = 0.72 h) 和脑 (t1/2 = 0.47 h) 中消除[2]

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

Animal Model: Wistar rats, spinal nerve ligation (SNL) and Streptozotocin (STZ; HY-13753)-induced diabetes mellitus models[1]
Dosage: 5, 12.5 or 25 mg/kg
Administration: Subcutaneous injecton, every second day for 10, 42 or 14 days
Result: Alleviated mechanical allodynia in the SNL animals. Treatment with the dose of 5 mg/kg alleviated mechanical hyperalgesia in the STZ-treated animals, while the 12.5 mg/kg dose was not effective. Concentration of 5 mg/kg attenuated cold allodynia in the STZ-treated animals during the first two weeks while the effect of 12.5 mg/kg was not significant.
Animal Model: Wistar rats, SNL-induced diabetes mellitus model[1]
Dosage: 12.5 or 25 mg/kg
Administration: Subcutaneous injecton, every second day for 10 days
Result: Led to a significant increase in the number of IB4 expressing neurons in the ipsilateral DRGs. The 12.5 mg/kg dose protected IB4-positive neurons from SNL-induced lesion.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
