  • p110β
描述 The PI3K/protein kinase B (AKT) pathway is commonly activated in several tumor types. Selective targeting of p110β could result in successful pathway inhibition while avoiding the on- and off-target effects of pan-PI3K inhibitors. GSK2636771 is a potent, orally bioavailable, adenosine triphosphate-competitive, selective inhibitor of PI3Kβ with IC50s of 3.5 nM, 20.49 nM, 40.53 nM for p110α p110β and p110γ, respectively[3]. In a vivo study, female nude mice with tumor xenografts were treated with vehicle or GSK2636771 at 1, 3, 10, or 30 mg/kg by oral gavage for 21 days and GSK2636771 resulted in tumor growth inhibition. In a cell study, C4-2B cells and its MDV3100-resistant subline was pretreated with GSK2636771 range from 1-100μM in 30mins. The result showed that treatment with GSK2636771 significantly increased G0/G1 population accompanied with a large reduction of S-phase cells not only in C4-2B cells but also in C4-2B/MDV-R cells, although the extent of G1/G0 phase arrest in MDV-R cells was less than that in the parental C4-2B cells[4].
