MedKoo CAT#: 206460

CAS#: 1357470-29-1

Description: ON123300 is a potent multikinase inhibitor and may be potential useful for brain tumor chemotherapy. ON123300 strongly inhibits Ark5 and CDK4, as well as growth factor receptor tyrosine kinases such as β-type platelet-derived growth factor receptor (PDGFRβ). ON123300 inhibits U87 glioma cell proliferation with an IC(50) 3.4 ± 0.1 μmol/L. ON123300 exhibits potent activity against mantle cell lymphomas (MCLs) both in vitro and in vivo. ON123300 might be an effective agent in MCL, including ibrutinib-resistant forms of the disease.
