AG14361 is a potent PARP-1 inhibitor, with a Ki of < 5 nM, and in permeabilized SW620 and intact SW620 cells, the IC50s are 29 nM and 14 nM, respectively. | [Definition]
ChEBI: LSM-1988 is a member of benzimidazoles. | [Biological Activity]
ag-14361 is a selective inhibitor of parp-1 with ki50 valueparp1 is a member of prap family and plays an important role in many cellular processes, such as dna repair, programmed cell death. it has been revealed that parp1 is abnormally expressed in a variety of cancers and many parp inhibitors have been developed as the anti-tumor drugs [1] [2] [3, 4].ag-14361 is a potent parp-1 inhibitor. when exposed hr and brca2-defective cells and parental cells to ag-14361, hr-defective cells were hypersensitive to the ag-14361 even at non-cytotoxic concentrations and lacking brca2 made the cells more sensitive to ag-14361 [5]. in human k562 cells, ag14361 treatment for 16 hours resulted in significant (~2-fold) potentiation of camptothecin-induced growth inhibition (gi50, 16 hours, camptothecin + ag14361 2.4 ± 0.1 nmol/l), cytotoxicity (lc50, camptothecin + ag14361 2.77 ± 0.55 nmol/l) and dna single-strand breaks via inhibiting parp-1 [1]. when tested with mmr-proficient (hct-ch3, a2780, and cp70-ch3) and mmr-deficient (hct116, cp70, and cp70-ch2) cells, mmr-proficient cells were more sensitivity to temozolomide compared with mmr-deficient cells after exposed to ag-14361 which inhibited parp1 activity [2].in mouse model xenografted with brca2-deficient and brca-2 proficient tumor cells, brca2 deficiency group had more response even completely regressed tumor compared with brca-2 proficient group when treated with ag-14361 [5]. | [in vivo]
AG14361 (5 and 15 mg/kg, i.p.) has no toxicity and does not inhibit the growth of tumor. However, AG14361 markedly enhances NSC 362856 activity against LoVo xenografts and delays tumor growth when combined with NSC 362856. AG14361 (15 mg/kg, i.p.) treatment before irradiation dramaticly increases the sensitivity to radiation therapy of mice bearing LoVo xenografts[1]. AG14361 (30 mg/kg) synergizes Lestaurtinib (HY-50867) activity on inhibiting breast cancer tumors in allografts[2]. | [target]
