AZD2014 is an orally bioavailable inhibitor of the mammalian target of rapamycin (mTOR) with potential antineoplastic activity.

在人类ER+乳腺癌移植模型中,AZD2014通过调控mTORC1和mTORC2底物,抑制肿瘤生长.

在乳腺癌细胞系（抗激素疗法的ER+细胞系）中,AZD2014抑制细胞生长,促使细胞凋亡。AZD2014能够抑制mTORC2的生物标记pAKTSer473和 pNDRG1Thr346。

Recombinant truncated FLAG-tagged mTOR expressed in HEK 293 cells is used in biochemical assays, together with a biotinylated p70S6K peptide substrate. Streptavidin donor and protein A acceptor beads are used to assemble the capture complex for generation of the assay signal. The activity of the lipid kinases, PI3K alpha, beta, delta, and gamma are measured using recombinant proteins and the lipid PIP2 as substrate. Assays for ATM and DNA-PK activity are performed. The mTOR cellular activity is measured in MDAMB468 cells, using an Acumen laser scanning cytometer to analyze the levels of phosphorylation of S6 (Ser235/236) and AKT (Ser473)[1].

AZD2014 is prepared in DMSO (10 mM) and stored under nitrogen, and then diluted with appropriate media before use[1]. Cells are plated in 96-well plates for the indicated time. For CellTiterGlo assays: CellTiterGlo is mixed with the cells. Cells are normalized to day 0 control and net growth is determined using the following formula: ((x?y)/(z?y))=net growth, where x=reading of treated sample at end of study, y=average reading on day 0, and z=reading of DMSO-treated sample at end of study. The concentration of DMSO does not exceed 0.03% for any experiment. For MTS assays: adherent cell lines are grown in 96-well plates. MTS reagent is added on day 0 and on day 3 post-AZD2014 addition. Suspension lines are assayed using the Alamar Blue reagent, 72 hours after AZD2014 addition[1].
