Biological Activity
|
PI3Kα-H1047R 26.3 nM (IC50) |
PI3Kα 94.6 nM (IC50) |
PI3Kα-IN-32 potently and selectively inhibits the enzymatic activity of the PI3KαH1047R mutant, with an IC50 of 26.3 nM[1].
PI3Kα-IN-32 (maximum 10 μM; 144 h) potently inhibits the proliferation of T47D HR+/HER2- breast cancer cells with an IC50 of 88.8 nM, and is 14.7-fold more selective for SK-BR-3 breast cancer cells expressing wild-type PI3Kα than for the former[1].
PI3Kα-IN-32 inhibits AKT phosphorylation in T47D HR+/HER2- breast cancer cells with an IC50 of 29.0 nM, and shows 5.8-fold selectivity for SK-BR-3 breast cancer cells expressing wild-type PI3Kα over the former[1].
PI3Kα-IN-32 (10 μM) exhibits high selectivity for PI3Kα, shows only weak activity against PI3Kδ and PIK3C3, and has no significant activity against the other 108 tested kinases[1].
