Ro 3280

Ro 3280 is a selective inhibitor of polo-like kinase 1 (Plk1), a proto-oncogene, with IC50 values of 3 and 6 nM in an enzymatic assay and H82 lung cancer cells, respectively. Ro 3280 is over 500-fold selective for PlK1 over a panel of 318 kinases. It inhibits tumor growth in a mouse xenograft model using the HT-29 colorectal cancer cell line, increases autophagy and mTOR phosphorylation in NB4 acute myeloid leukemia cells, and induces apoptosis in human bladder cancer and leukemia cells.Formal Name: 4-[(9-cyclopentyl-7,7-difluoro-6,7,8,9-tetrahydro-5-methyl-6-oxo-5H-pyrimido[4,5-b][1,4]diazepin-2-yl)amino]-3-methoxy-N-(1-methyl-4-piperidinyl)-benzamide.
