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)).
GMB-475 (0.01-100 μM, 3 days) inhibits leukemic stem cell viability in chronic myeloid leukemia (CML) by targeting degradation of BCR-ABL1 protein kinase and inhibiting downstream STAT5 biomarkers[1]. GMB-475 (0-5 μM, 48 h) blocks multiple molecules in the JAK-STAT pathway, blocks the cell cycle and promotes apoptosis in Ba/F3 cells harboring the BCR::ABL1 mutant[2].

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].
