GSK215 is a potent and selective PROTAC focal adhesion kinase (FAK) degrader. GSK215 is designed by a binder for the VHL E3 ligase and the FAK inhibitor VS-4718. GSK215 induces rapid and prolonged FAK degradation, giving a long-lasting effect on FAK levels and a marked pharmacokinetic/pharmacodynamics (PK/PD) disconnect[1]. GSK215 (0.1-1000 nM; 2 hours) effectively increases the FAK degradation by >90% and determines a DC50 of 1.3 nM[1]. GSK215 (8mg/kg; i.h.) treatment shows the Cmax and tmax values of 526 ng/mL and 0.33 hours, respectively[1].

GSK215 (0.1-1000 nM; 2 h) effectively increases the FAK degradation by >90% and determines a DC50 of 1.3 nM in A549 cells. Its induced degradation is proteasome and ubiquitin-dependent. GSK215 (above 100 nM, 6h) primarily reduces kinases CDK7, RPS6KA3, MET, and GAK. This compound (100 nM, 48 h) inhibits migration, invasion, and collagen deposition in A549 cells.
