| Bioactivity | KPT-6566 is a selective and covalent prolyl isomerase PIN1 inhibitor, covalently binds to the catalytic site of PIN1, selectively inhibits and degrades PIN1. KPT-6566 shows an IC50 value of 640 nM and a Ki value of 625.2 nM for PIN1 PPIase domain. KPT-6566 can be used for the research of cancer[1]. |
