MLN1117

MLN1117 (INK1117, TAK-117, Serabelisib) is a potent, selective PI3K p110α inhibitor with IC50 of 15 nM, displays >300-fold selectivity over p110β/γ/δ and mTOR; inhibits AKT phosphorylation and growth in PIK3CA mutant breast cancer cells with IC50 of 2 uM, significantly suppresses B cell proliferation driven by anti-IgM alone but not by anti-IgM plus IL-4; abrogates immune checkpoint mediated proliferation in peripheral T-cell lymphoma combined with alisertib.Breast Cancer Phase 2 Clinical (In Vitro) :Serabelisib (MLN1117) inhibits Akt phosphorylation and growth in PIK3CA mutant breast cancer cells with IC50s around 2 μM, yet has no effect on cells lacking PTEN. BCR-stimulated B cells treated with 1 μM Serabelisib (MLN1117) displays a significant reduction (up to 50%) in the magnitude of the phosphorylated Akt (p-Akt) signal measured by intracellular flow cytometry. The effect of Serabelisib is dose-dependent. (In Vivo) :Treatment with Serabelisib (MLN1117) at 30 and 60 mg/kg causes little reduction of TNP-specific IgG3. Notably, reduction of TNP-specific IgG3 at higher doses of Serabelisib (MLN1117) (120 mg/kg) is observed, consistent with the partial reduction in cell division in B cells treated with Serabelisib before anti-IgM stimulation. However, 120 mg/kg is above the effective dose of Serabelisib (MLN1117) for tumor growth inhibition (30-60 mg/kg) .
