描述 | ON 123300 is multikinase inhibitor with 3.87, 9.82, 4.95, 26, 26 and 144nM for Cdk4/cyclin D1, CDK6/cyclinD1, ARK5, FGFR1, PDGFRβ and PI3K-δ, respectively. ON 123300 exhibited potent activity against mantle cell lymphomas Z138C and GRANTA 519 with GI50 values of 25nM and 35nM, respectively, as well as inhibited the proliferation of cell lines of different tumor types with GI50 values ranging in 0.1-0.6μM. As a dual inhibitor of both Cdk4/6 and PI3K-δ, ON123300 inhibited phosphorylation of both Rb family proteins and proteins associated with the PI3K/AKT pathway, at concentration of 2.5-10μM post 24h, with apoptosis observed. Treatment of ibrutinib-sensitive and -resistant patient-derived MCLs with ON123300 also triggered apoptosis and inhibition of the Rb and PI3K/AKT pathways. Administration of ON 123300 at dose of 100mg/kg, i.p., daily for 2 weeks significantly inhibited tumor growth in a nude mouse model of Z138C MCL. |
