In vitro

AZD2014 is a close analogue of AZD8055 and a selective inhibitor of mTOR kinase. AZD2014 has greater inhibitory activity against mTORC1 compared to rapamycin: AZD2014 decreases p4EBP1 Thr37/46, inhibits the translation initiation complex and decreases overall protein synthesis while rapamycin has no effect. AZD2014 also inhibits the mTORC2 biomarkers pAKTSer473 and pNDRG1Thr346. AZD2014 has broad antiproliferative activity across multiple tumour cell lines. In particular, AZD2014 induces growth inhibition and cell death in breast cancer cell lines, including ER+ cell lines with acquired resistance to hormone therapy. [1]

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
