Description: Roniciclib, also known as BAY 1000394; is an orally bioavailable cyclin dependent kinase (CDK) inhibitor with potential antineoplastic activity. pan-CDK inhibitor BAY1000394 selectively binds to and inhibits the activity of CDK1/Cyclin B, CDK2/Cyclin E, CDK4/Cyclin D1, and CDK9/Cyclin T1, serine/threonine kinases that play key roles in the regulation of the cell cycle progression and cellular proliferation. Inhibition of these kinases leads to cell cycle arrest during the G1/S transition, thereby leading to an induction of apoptosis, and inhibition of tumor cell proliferation. (last updated: 3/2/2016)
