| | Kinase Activity Assay |
| Description: | In some embodiments, the subject compounds inhibit a P14-kinase, as determined by a kinase activity assay, e.g., by an assay that determines the level of incorporation of radiolabeled phosphate from [γ-32P]-ATP into a substrate molecule after treatment with a subject compound, relative to a control, by measuring the beta-particle emission rate using a scintillation counter or phosphorimaging. In certain embodiments, the subject compounds have an IC50 value for PI4K-IIIβ of less than about 1 μM, less than about 0.2 μM, less than about 0.1 μM, less than about 10 nM, less than about 1 nM, or even less, such as described in Tables 2-3. In certain embodiments, the subject compounds have an IC50 value for PI4K-IIIα of less than about 50 μM, less than about 10 μM, less than about 1 μM, less than about 0.1 μM, less than about 10 nM, less than about 1 nM, or even less, such as described in Tables 2-3. In certain further embodiments, the subject compounds have an IC50 value for PI4K-IIIβ of 50 μM or less, [etc., etc.], 10 nM or less, 6 nM or less, or even less, such as described in Tables 2-3. In certain further embodiments, the subject compounds have an IC50 value for the PI3-kinase p110α-p85 complex of between about 8 and about 10 nM, between about 8 μM and about 10 μM, or even more. |
