MLN1117 is a selective p110α inhibitor with an IC50 of 15 nM.

IC50 & Target

IC50: 15 nM (p110α), 4500 nM (p110β), 1900 nM (p110γ), 13900 nM (p110δ), 1670 nM (mTOR)[1]

In Vitro

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 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 MLN1117 is dose-dependent[1].

In Vivo

Treatment with MLN1117 at 30 and 60 mg/kg causes little reduction of TNP-specific IgG3. Notably, reduction of TNP-specific IgG3 at higher doses of MLN1117 (120 mg/kg) is observed, consistent with the partial reduction in cell division in B cells treated with MLN1117 before anti-IgM stimulation. However, 120 mg/kg is above the effective dose of MLN1117 for tumor growth inhibition (30-60 mg/kg)[1].

Cell Assay

A total of 5000 SK-OV-3 and U87MG cell lines /well in low serum media (0.2% FBS) are seeded in triplicate wells of a 96-well flat bottom culture plate for 18 h to adhere. Media is aspirated and inhibitors in 0.2% FBS media are added to each well at the indicated concentrations. After 48 h, cell viability is determined using the MTS assay (Cell Titer 96 Aqueous One solution cell proliferation assay kit) with absorbance (490 nm) measured in a microplate spectrophotometer[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration

Wild-type 8-week-old Balb/cJ mice are used for all experiments. MLN1117 and GDC-0941 are given by oral gavage using a sterile disposable 20-guage 1.5′ feeding needle. IC87114 is delivered via intraperitoneal injection. For the non-immunization experiment, 2 mice per group (Vehicle, GDC-0941, and MLN1117) are given the indicated drugs for 9 days before sacrificing on day 10. For the immunization experiment, 4 mice per group are used to perform two independent studies comparing GDC-0941 or IC87114 to MLN1117. In all cases, the vehicle group receive both vehicles used to formulate the two different drugs. Mice are treated with the drugs throughout day -1 to day 13. On day 0, all mice are immunized with NP-OVA precipitated in alum. Drug treatment is stopped on day 13 and mice are sacrificed for collection of serum and spleens.
