研究领域:Cell Cycle/DNA Damage | Apoptosis
In Vitro: AT7519 (0-4 µM) results in dose-dependent cytotoxicity with IC50s ranging from 0.5 to 2 µM in MM cells, and this induced cytotoxicity is associated with GSK-3β activation independent of transcriptional inhibition. AT7519 overcomes proliferative advantage conferred by cytokines and the protective effect of BMSC. AT7519 (0.5 µM) induces apoptosis of MM cells in a time-dependent manner. Moreover, AT7519 (0.5 µM) inhibits phosphorylation of RNA polymerase II CTD and partially inhibits RNA synthesis in MM.1S cells. AT7519 (250 nM) inhibits cell cycle progression in human tumor cell lines. AT7519 also induces apoptosis of human tumor cell lines. AT7519 (100⁻⁷00 nM) induces apoptosis in leukemia cell lines. AT7519 also inhibits transcription in human tumor cell lines. Furthermore, AT7519 inhibits RNA polymerase II and reduces antiapoptotic protein levels.
In Vivo: AT7519 inhibits tumor growth in a human MM xenograft mouse model. AT7519 (4.6 and 9.1 mg/kg/dose) inhibits the growth of early-stage HCT116 tumor xenografts. AT7519 (10 mg/kg, i.p.) also inhibits the target CDKs in HCT116 tumor-bearing BALB/c nude mice.
