实验参考方法

Cell experiment [1]:

Cell lines

NPC cell lines (CNE-2, 5-8F, and 6-10B)

Preparation method

The solubility of this compound in DMSO is >25.3mg/mL. 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.

Reacting condition

0.003 mmol/L

Applications

GSK2126458 decreased the viability of NPC cells at low nanomolar concentrations and in a concentration- and time-dependent manner. GSK2126458 inhibited migration and invasion of NPC cells. Treatment with GSK2126458 led to an increased percentage of cells in G1 phase.

Animal experiment [1]:

Animal models

Female BALB/c-nu/nu nude mice bearing 5-8F cells

Dosage form

300 μg/kg, Intragastric administration once daily for 5 consecutive days each week.

Application

The combination of IR with GSK2126458 resulted in >50% reduction in xenograft volume and tumor regrowth delay. Treatment with GSK2126458 or PKI-587 alone slightly inhibited tumor growth.

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.

产品描述

GSK2126458 is an inhibitor of PI3K/mTOR with Ki value of 19 pM for PI3K [1].
PI3K (phosphoinositide 3-kinase) plays an important role in regulating cell growth and transformation, and mTOR (mammalian target of rapamycin) which works as a class IV PI3K protein kinase, is also a crucial regulator of cell growth [2]. It has been shown that up-regulation of PI3K/mTOR (phosphatidylinositol-3' kinase/mammalian target of rapamycin) signaling is widespread in carcinoma which may be worked as a biomarker used in clinic [3].
GSK2126458 is a highly potent inhibitor of PI3K/mTOR. When subjected to colorectal cancer cell lines, GSK2126458 could potentiate the cells antiproliferative activity via combining with DDR1-IN-1[4]. In BT474 breast cancer lines, treated with GSK2126458 could be the arrest of G1 cell cycle and thus inhibit cell proliferation [5]. GSK2126458 also could improve the sensitivity of NPC cells to radiation and suppress tumor progression [1].  
In a 5-8F xenograft model with NPC, treated the mouse with GSK2126458 combining of IR significantly inhibited the tumor growth [1]. In mice injected with cancer cells from melanoma patient resisted to the combination of divergent and trametinib, GSK2126458 combined with dabrafenib, trametinib treatment resulted in sustained inhibition of tumor growth[3].
GSK2126458 may play a significant role in regulating autophagy [6].
