生物活性
WYE-125132 is a highly potent, ATP-competitive and specific mTOR kinase inhibitor with an IC50 of 0.19 nM. WYE-125132 blocked the activity of the both of mTORC1 and mTORC2 in various models of cancer in vitro and in vivo. WYE-125132 is 5,000-fold more selective than PI3Ks. Moreover, WYE-125132 completely blocked amino acid-induced phosphorylation of Maf1, just as S6K1, and 4E-BP1 via the inhibition of mTOR. WYE-132-treated MG63 markedly upregulated the Maf1 amouts in the nucleus. WYE-125132 showed a substantially more effective inhibition in many respects, including cancer cell growth and survival, protein synthesis bioenergetic metabolism, and adaptation to hypoxia by contrast with the rapalog temsirolimus/CCI-779.

细胞系 | WYE-125132 |
方法 | Obtaining cell lines of MDA-MB-361, MDA-MB-231, MDA-MB-468, BT549, LNCap, A549, H1975, H157, H460, U87MG, A498, 786-O, HCT116, MG63, Rat1, HEK293, and HeLa from the American Type Culture Collection. Describing cell growth assays and IC50 determination as follows. For tumor cell growth assays, plating cells in 96-well culture plates at 1000 to 3000 cells per well for 24 hours, treating with DMSO or various doses of WYE-125132. Viable cell densities are determined three days later by MTS assay employing an assay kit following the kit assay protocol.Calculating the effect of each treatment as percent of control growth relative to the DMSO-treated cells grown in the same culture plate. Ploting inhibitor dose response curves for determination of IC50 values. |

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
