IC50 & Target[1]



In Vitro

GSK2636771 treatment causes cell viability significantly more decreased in the control cells (p110β-reliant PTEN-deficient PC3 prostate and BT549 and HCC70 breast cancer cell lines) than in PTEN-mutant and PTEN wild-type EEC cells. Inhibition of p110β by GSK2636771 or AZD6482 leads to a marked decrease of AKT phosphorylation only in the control prostate and breast cancer cell lines, whereas only marginal effects on AKT activation are observed in EEC cells[1].

In Vivo

GSK2636771 is a p110β inhibitor, and the p110β primes cells for response to growth factor stimulation. While p110β inhibition suppresses cell and tumor growth, dual targeting of p110α/β enhances apoptosis and provides sustained tumor response in mice model[2].

Cell Assay

Cells are plated in 96-well microtiter plates at densities ranging from 1,500 to 15,000 cells/well, optimized for untreated control cells to be 80-90% confluent at the endpoint of the experiment. After 24 h, cells are treated with serial dilutions (100 pM to 10 µM) of the PI3K pathway inhibitors GDC-0941, A66, TGX-221, GSK2636771, AZD6482, Temsirolimus, AZD8055, PF-04691502, and of the MAPK pathway inhibitors AZD6244, PD0325901, AZD628, and PLX4032. Cell viability is assessed after 72 h of treatment by incubation with CellTiter Blue for 1.5 h. The drug concentration required for survival of 50% of cells relative to untreated cells is determined using GraphPad Prism version 5.0 d. Cell lines that fail to achieve the SF50 to a given drug are nominally assigned as the highest concentration screened (10 µM). At least three independent experiments in triplicate per cell line/targeted drug are performed. Association between a mutation and response to a targeted agent is determined using a Fisher’s exact test, and a two-tailed P value.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
