产品描述:
Polo-like kinases (Plks) are serine/threonine kinases with key roles in cell cycling.{29228} BI-6727 is a dihydropteridinone that inhibits Plk1, Plk2, and Plk3 (IC50s = 0.87, 5, and 56 nM, respectively), inducing mitotic arrest and apoptosis.{29375} It inhibits proliferation of multiple cancer cell lines with EC50 values ranging from 11-37 nM and prevents the growth of various human carcinoma xenografts in mice.{29375} BI-6727 was found to reverse ABC-efflux transporter-mediated multidrug resistance activity through its inhibition of the transport activity of ABCB1 and ABCG2, thus promoting mitotic arrest in resistant cancer cells.{29376}
