PLK1/BRD4-IN-1 (9b) is an orally active dual PLK1 and BRD4 inhibitor with IC50 values of 22 nM and 109 nM against PLK1 and BRD4, respectively. PLK1/BRD4-IN-1 induces cell cycle arrest and apoptosis, downregulates the transcription of several proliferation-related oncogenes, and exhibits favorable in vivo antitumor activity[1].
Poloxin is a non-ATP competitive Polo-like Kinase 1 (PLK1) inhibitor that targets the polo-box domain, with an IC50 of appr 4.8 μM.
SBE13 Hydrochloride is a potent and selective Plk1 inhibitor, with an IC50 of 200 pM; SBE13 Hydrochloride poorly inhibits Plk2 (IC50>66 μM) or Plk3 (IC50=875 nM).
MLN0905 is a potent PLK1 inhibitor, with an IC50 of 2 nM.
PLK1-IN-4 is a potent and selective PLK1 inhibitor with IC50 < 0.508 nM. PLK1-IN-4 has broad antiproliferative activity against a variety of cancer cell lines. PLK1-IN-4 induces mitotic arrest at the G2/M phase checkpoint, leading to cancer cell apoptosis. PLK1-IN-4 can be used for researching hepatocellular carcinoma[1].
PLK1-IN-7 (compound 30e) is a potent PLK1 inhibitor, with an IC50 of 0.66 nM. PLK1-IN-7 exhibits antiproliferative and antitumor activities[1].
