Biological Activity

OSI-027 is a potent, orally bioavailable mammalian target of rapamycin (mTOR) kinase inhibitor with potential antineoplastic activity. OSI-027 shows more than 100-fold selectivity for mTOR relative to PI3Kα, PI3Kβ, PI3Kγ and DNA-PK. OSI-027 inhibits phosphorylation of the mTORC1 substrates 4E-BP1 and S6K1 as well as the mTORC2 substrate AKT in diverse cancer models in vitro and in vivo. OSI-027 potently inhibits proliferation of several rapamycin-sensitive and -insensitive nonengineered and engineered cancer cell lines and also, induce cell death in tumor cell lines with activated PI3K-AKT signaling. In contrast to rapamycin, OSI-027 induced apoptosis in a variety of lymphoid cell lines and clinical samples, including specimens of B-cell acute lymphocytic leukemia (ALL), mantle cell lymphoma, marginal zone lymphoma and Sezary syndrome. Furthermore, OSI-027 shows superior efficacy compared with rapamycin in COLO 205 and GEO colon cancer xenograft models. OSI-027 is currently in phase I clinical trials in cancer patients.

Method Western blot
Cell Lines PDAC cell lines
Concentrations 5 and 10 μM
Incubation Time 48 and 72 h
Results Flow cytometry assay showed 5 μM OSI-027 induced cell cycle arrest in the G0/G1 phase in Panc-1, BxPC-3, and CFPAC-1 cells, whereas RAPA had little effect on cell cycle. Moreover, 10 μM OSI-027 further upregulated the proportion of cells arrested in G0/ G1 phase

Cell Experiment
Cell lines MDA-MB-231, MDA MB 435, PC-3, OVCAR-3, A549, DU145, NCI-H2122, U 87 MG and ACHN cell lines
Preparation method For assays of cell proliferation, cells were seeded into 96-well plates and incubated for 3 days in the presence of OSI-027 or OXA-01 at various concentrations. Inhibition of cell growth was determined by luminescent quantification of intracellular ATP content using CellTiterGlo® (Promega). Proliferation on Day 0 vs. 72h was used to plot dose-response curves for IC50 calculations and to determine cell death.
