Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/19383823

Volasertib (BI 6727), a dihydropteridinone derivative, is a small-molecule cell cycle inhibitor of polo-like kinase-1 (PLK-1). Volasertib induces G2-M arrest and induction of apoptosis in cancer cells and potently inhibits tumor growth in xenograft models. Boehringer Ingelheim is developing intravenously administered volasertib for the treatment of acute myeloid leukaemia (AML), myelodysplastic syndromes (MDS), chronic myelomonocytic leukaemia (CMML), non-small cell lung cancer, urogenital cancer, ovarian cancer and solid tumours.

Curator's Comment: Volasertib (BI 6727) can cross an in vitro blood-brain barrier model. In vivo, volasertib induced regressions of brain tumors in several xenograft models. No human data available.
