| 产品描述 | GB1107 is a potent, selective, orally active inhibitor of Galectin-3 (Gal-3) with a Kd of 37 nM for human Galectin-3. GB1107 reduces human and mouse lung adenocarcinoma growth and blocks metastasis in the syngeneic model[1].
Treatment with GB1107 (0-1 μM) increases tumor M1 macrophage polarization and CD8+ T cell infiltration in LLC cells by flow cytometric analysis. GB1107 potentiates the effects of a PD-L1 immune checkpoint inhibitor to increase expression of cytotoxic (IFN-γ, granzyme B, perforin-1, Fas ligand) and apoptotic (cleaved caspase-3) effector molecules[1].
GB1107 (10 mg/kg, p.o., once daily from day 18-30 post implantation) treatment results in significantly reduced tumor growth and final tumor weights[1].
