Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/26652717 | https://www.ncbi.nlm.nih.gov/pubmed/23881923 | https://www.fda.gov/Drugs/InformationOnDrugs/ApprovedDrugs/ucm623540.htm

BMN-673 (8R,9S) is the (8R,9S) enantiomer of BMN-673, known as talazoparib. BMN 673 is a novel inhibitor of nuclear enzyme poly (ADP-ribose) polymerase (PARP) with potential antineoplastic activity.

CNS Activity

Curator's Comment: This lack of intracranial efficacy is associated with limited brain distribution due to active efflux mediated by Mdr1 at the blood-brain barrier (animal study). No human data available.
