Catalogue Number | 151889 |
Antigen/Gene or Protein Targets | DNA-dependent protein kinase (DNA-PK) |
Synonyms | DNA-dependent protein kinase (DNA-PK) inhibitor NU7441 |
Type | Inhibitor |
Relevance | NU7441 is a highly potent and selective DNA-PK inhibitor. |
On Target IC50 | 14 nM |
Selectivity | Also inhibits PI3K with IC50 of 5 μM in cell-free assays. |
Molecular Formula | C25H19NO3S |
Molecular Weight (g/mol) | 413.49 g/mol |
In vivo applications | NU7441 intraperitoneally administrated at dose of 10 mg/kg maintains for at least 4 hours shows nontoxic and increases etoposide-induced tumor growth delay 2-fold in mice bearing SW620 xenografts. |
In vitro applications | NU7441 increases the persistence of γH2AX foci after ionizing radiation–induced or etoposide-induced DNA damage. NU7441 (0.5 μM or 1 μM) appreciably increases G2-M accumulation induced by ionizing radiation, etoposide, and doxorubicin in both SW620 and LoVo cells. NU7441 causes persistence of doxorubicin- and ionising radiation-induced DNA double-strand break and also slightly decreases homologous recombination activity DNA-PK-proficient M059-Fus-1 and DNA-PK-deficient M059 J human tumour cells. NU7441 inhibits UV-induced RPA p34 hyperphosphorylation in a dose-dependent manner both in cells lacking and cells expressing polymerase η. NU7441 increases levels of fludarabine-induced γH2AX foci and correspondingly decreased fludarabine-induced cell death in chronic lymphocytic leukemia cells. NU7441 also inhibits mitoxantrone-induced DNA-PKcs autophosphorylation and repair in chronic lymphocytic leukemia cells. |
