| Hazard Information | Back Directory | [Description]
GMB-475 acts as a degrader of BCR-ABL 1 tyrosine kinase and as a recruiter of the E3 ligase Von Hippel Lindau (VHL) resulting in ubiquitination and subsequent degradation of oncogenic fusion proteins. | [Uses]
GMB-475 is a potent BCR-ABL1 PROTAC based on Von Hippel-Lindau (VHL). GMB-475 targets the nutmeg pocket of ABL1 in an ectopic manner and degrades BCR-ABL1 protein through the ubiquitin proteasome pathway. GMB-475 inhibits the proliferation of human K562 cells and mouse Ba/F3 cells, and is used for the study of chronic myeloid leukemia. (Blue: VHL ligand (HY-125845); Black: Linker; Pink: BCR-ABL1 ligand (HY-11007))[1][2]. | [Biological Activity]
GMB-475, a BCR-ABL1 Inhibitor Based on PROTAC, Has the Potential to Overcome BCR-ABL1-Dependent Drug Resistance. In both human CML K562 cells and murine Ba/F3 cells expressing BCR-ABL1, GMB-475 induces rapid proteasomal degradation and inhibition of downstream biomarkers. Notably, GMB-475 inhibits the proliferation of certain clinically relevant BCR-ABL1 kinase domain point mutants. GMB-475 reduces viability and increases apoptosis in primary chronic myeloid leukemia CD34+ cells, with no effect on healthy CD34+ cells. Furthermore, GMB-475 degrades BCR-ABL1 and reduces cell viability in primary chronic myeloid leukemia stem cells. | [in vivo]
GMB-475 (5 mg/kg; once every two days; 10 days; i.p.) improves chronic myeloid leukemia in mice with BCR::ABL1 mutant by targeted degradation of BCR-ABL1b and combined with dasatinib (HY-10181)[2]. | Animal Model: | 8-week-old Balb/c mice were injected with Ba/F3-MG-p210-Luc cells via tail vein to establish a chronic myeloid leukemia (CML) mouse model[2]. | | Dosage: | 5 mg/kg | | Administration: | Intraperitoneal injection (i.p.); once every two days; 10 days | | Result: | Showed a trend of reducing the tumor burden and prolonging the survival of the CML mouse model. |
