AT7519 (AT7519M) TFA as a potent inhibitor ofCDKs, withIC₅₀s of 210, 47, 100, 13, 170, and<10 nm forCDK1,CDK2,CDK4toCDK6, andCDK9, respectively.

AT7519 (0-4 μM) TFA 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 TFA overcomes proliferative advantage conferred by cytokines and the protective effect of BMSC. AT7519 (0.5 μM) TFA induces apoptosis of MM cells in a time-dependent manner. Moreover, AT7519 (0.5 μM) TFA inhibits phosphorylation of RNA polymerase II CTD and partially inhibits RNA synthesis in MM.1S cells^[1]. AT7519 (250 nM) TFA inhibits cell cycle progression in human tumor cell lines. AT7519 TFA also induces apoptosis of human tumor cell lines^[2]. AT7519 (100-700 nM) TFA induces apoptosis in leukemia cell lines. AT7519TFA also inhibits transcription in human tumor cell lines. Furthermore, AT7519 TFA inhibits RNA polymerase II and reduces antiapoptotic protein levels^[3].

AT7519 TFA inhibits tumor growth in a human MM xenograft mouse model^[1]. AT7519 (4.6 and 9.1 mg/kg/dose) inhibits the growth of early-stage HCT116 tumor xenografts. AT7519 (10 mg/kg, i.p.) TFA also inhibits the target CDKs in HCT116 tumor-bearing BALB/c nude mice^[2].
