KDM5-C70

KDM5-C70 is an ethyl ester derivative of KDM5-C49 and a potent, cell-permeable and pan-KDM5 histone demethylase inhibitor. KDM5-C70 has an antiproliferative effect in myeloma cells, leading to genome-wide elevation of H3K4me3 levels[1][2].

KDM5 histone demethylase[1][2]

KDM5-C70 (10-9-10-5 M; 7 days; MM.1S myeloma cells) treatment shows antiproliferative effects after 7 days of treatment at elevated concentrations (estimated 50% reduction of viability/proliferation for KDM5-C70 at ~20 μM)[1]. KDM5-C70 (50 μM; 7 days; MM.1S myeloma cells) treatment decreases the level of phosphorylation of retinoblastoma protein (Rb), while leaving the total level of phosphorylated Rb (pRb) unchanged, indicating impairment of cell cycle progression[1]. Chromatin immunoprecipitation followed by next-generation sequencing shows an increase in H3K4me3 levels around transcription start sites with KDM5-C70 but little change with GSK467A at 50 μM inhibitor concentrations[1]. Cell Viability Assay[1] Cell Line: MM.1S myeloma cells Concentration: 10-9-10-5 M Incubation Time: 7 days Result: Showed antiproliferative effects after 7 days of treatment at elevated concentrations. Western Blot Analysis[1] Cell Line: MM.1S myeloma cells Concentration: 50 μM Incubation Time: 7 days Result: Decreased the level of phosphorylation of retinoblastoma protein (Rb).
