PF-5236216
PF-5236216 is a brain-penetrant CK1δ/CK1ε inhibitor with IC50 values of 8 and 36 nM. PF-5236216 inhibits CK1δ and CK1ε-mediated PER3 nuclear translocation. PF-5236216 forms an H-bond with the backbone NH of Leu85, hydrophobic stacking with Met82, and a water-mediated H-bond with Lys38 of CK1δ. PF-5236216 can be used as a tool ligand for CNS PET studies.
