GSK215 是一种有效且具有选择性的PROTAC粘着斑激酶(FAK)降解剂,pDC50值为 8.4。GSK215 是由 VHL E3 连接酶粘合剂和FAK 抑制剂 VS-4718 联合设计的。GSK215 诱导 FAK 快速而持久性的降解,对 FAK 水平产生长期影响,并显著降低药代动力学/药效学 (PK/PD)。
生物活性 | GSK215 is a potent and selectivePROTACfocal adhesion kinase (FAK)degrader with a pDC50of 8.4. GSK215 is designed by a binder for the VHL E3 ligase and theFAK inhibitorVS-4718. GSK215 induces rapid and prolongedFAKdegradation, giving a long-lasting effect onFAKlevels and a marked pharmacokinetic/pharmacodynamics (PK/PD) disconnect[1]. |
IC50& Target | PROTAC; pDC50: 8.4 (FAK)[1] |
体外研究 (In Vitro) | GSK215 (0.1-1000 nM; 2 h) effectively increases the FAK degradation by >90% and determines a DC50of 1.3 nM in A549 cells[1]. GSK215 induced degradation is proteasome and ubiquitin dependent[1]. GSK215 (above 100 nM, 6h) reduces primarily kinases CDK7, RPS6KA3, MET and GAK[1]. GSK215 (100 nM, 48 h) inhibits migration, invasion and collagen deposition in A549 cells[1].
Western Blot Analysis[1] Cell Line: | A549 cells | Concentration: | 0.1-1000 nM | Incubation Time: | 2 h | Result: | Increased the FAK degradation. |
Cell Migration Assay[1] Cell Line: | A549 cells | Concentration: | 100 nM | Incubation Time: | 48 h | Result: | Inhibited cell migration. |
Cell Invasion Assay[1] Cell Line: | A549 cells | Concentration: | 100 nM | Incubation Time: | 48 h | Result: | Inhibited cell invasion. |

体内研究 (In Vivo) | GSK215 (8 mg/kg; i.h.; once) degrades FAK, and shows the Cmaxand tmaxvalues of 526 ng/mL and 0.33 hours, respectively[1].
Animal Model: | Male CD1 mice (P878/881A), 7-9 weeks[1] | Dosage: | 8 mg/kg | Administration: | Single subcutaneous injection | Result: | Caused a rapid and profound degradation of FAK in liver over time, with a maximal degradation of ~85% being achieved within 18 h. Endogenous FAK was found to still be reduced by ~60% at 96 h post-dose.The Cmaxand tmaxwere 526 ng/mL and 0.33 hours, respectively. |
