About Alvocidib

Alvocidib is a potent small molecule inhibitor of cyclin-dependent kinases (CDKs) in development as a front-line combination therapy for acute myeloid leukemia (AML) and relapsed/refractory AML. CDKs are regulatory proteins that are critical to cellular replication and regulation of gene expression. Given the key role CDK de-regulation plays in unchecked cell division and growth, CDKs remain an attractive target for the treatment of various cancers.
