Description

Biochem/physiol Actions

Potent and selective peptidyl-prolyl cis-trans isomerase (PPIase) Pin1 covalent inhibitor with anti-cancer efficacy in cultures and in vivo.

KPT-6566 is a potent and selective peptidyl-prolyl cis-trans isomerase (PPIase) Pin1 inhibitor (IC50 = 640 nM) that targets Pin1 catalytic site for covalent modification, resulting in Pin1 degradation and the release of ROS-generating and DNA-damaging quinone-mimicking KPT-6566-B. KPT-6566 inhibits the proliferation of wild-type, but not Pin1-/-, MEFs (1-5 µM for 48h) with concomitant reduction of cellular pRB and Cyclin D1 hyperphosphorylation. KPT-6566 induces cancer cell death in cultures (1-10 µM for 48h) and reduces MDA-MB-231 lung metastasis in mice in vivo (5 mg/kg/d i.p.). KPT-6566 is more potent than juglone and does not affect the PPIase activity of GST-FKBP4 or GST-PPIA.
