Definition
ChEBI: LSM-1988 is a member of benzimidazoles.
Biologische Aktivität
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].
