Poloppin II
Poloppin II is an orally active PBD inhibitor that blocks the binding of phosphopeptide substrates to PLK1/PLK2 PBD, with IC50 values of 41 µM and 105 µM for human PLK1/PLK2 PBD, respectively. Poloppin II binds to PLK4 PBD to inhibit PLK4-dependent mitotic functions. Poloppin II can be used in research on kras-mutant colorectal cancer.

In Vitro
Poloppin II (16 h) induces mitotic arrest in HeLa cells with EC50 61 nM (MI EC50 0.069 μM; 81% max)[1].
Poloppin II (1 h at 22°C) inhibits phosphopeptide binding to PLK1 PBD with IC50 41 μM and to PLK2 PBD with IC50 105 μM in FP assays[1].
Poloppin II (100 μM; 1 h at 37°C; 3 min over 42-66°C gradient) engages PLK1 and PLK4 in NanoLuc thermal shift assays in HeLa cells[1].
Poloppin II is inactive against hERG and stable in human and mouse hepatocytes[1].
