Catalog Number: 4840
Chemical Name: 4-Ethyl-N-[4-[2-(4-morpholinyl)-4-oxo-4H-1-benzopyran-8-yl]-1-dibenzothienyl]-1-piperazineacetamide
Biological Activity
Dual PI 3-K and DNA-PK inhibitor (IC50 values are <0.1, 0.5, 4 and 19 nM for PI 3-Kδ, PI 3-Kβ, PI 3-Kα and DNA-PK respectively). Inhibits proliferation of MCF7 cells in vitro and delays growth of MCF7 xenografts in mice. Also enhances CRISPR-Cas9-mediated homology-directed repair (HDR) efficiency ~2 to 4-fold, and decreases nonhomologous end-joining (NHEJ) frequency ~40%; maximum effect seen at 250 nM.
