Biological Activity

• Description: CP-466722 is an potent and reversible ATM inhibitor.
• Targets: ATM
• In Vitro: In vitro, CP-466722 is identified as a potential inhibitor to decrease the activity of purified ATM kinase to phosphorylate GST-p53(1–101) substrate. In addition, CP-466722 also shows the inhibitory activities against abl and src kinases. ^[1] In HeLa cells, CP-466722 at doses of 6μM, results in the inhibition in ATM-dependent phosphorylation by reversibly inhibiting ionizing radiation (IR)-induced ATM kinase activity. Besides, ATM-dependent p53 induction is also inhibited by CP-466722 in MCF-7 human breast cancer cells and primary and immortalized diploid human fibroblasts. ^[1] In response to IR, CP-466722 increased proportion of cells with G2/M DNA content and reduces proportion of cells with G1-phase DNA content in HeLa cells. ^[1] Transient exposure to CP-466722 for a period of 4 hours sensitizes HeLa cells to IR without affecting cell plating nor cell viability. ^[1]

Protocol

• Protocol: Cell Assay ^[1]
• Cell Lines: HeLa and A-T
• Concentrations: 0-6 μM
• Incubation Time: 4 hours
• Methods: HeLa or A-T (GM02052 expressing hTERT) cells are plated in triplicate and incubated for 24 hours. Cells are pre-treated: DMSO, CP466722 or KU55933 prior to IR (0-10Gy). Cells are incubated for 4 hours following IR before media is removed, cells washed (PBS), trypsinsed, counted and re-plated (2000 cells/plate, 10 cm plates) in the absence of drug and incubated for 10 days. Prior to colony counting, cells are washed (PBS), stained (PBS, 0.0037%v/v-formaldehyde, 0.1%w/v-crystal violet), rinsed (dH₂O) and dried. Defined populations (>50 cells) are counted as one surviving colony, data are calculated as percentage surviving colonies relative to control plates +/? SE.
