Biological target:

GB1107 is a potent, selective, orally active inhibitor of Galectin-3 (Gal-3) with a Kd of 37 nM for human Galectin-3.

In vitro activity:

Additionally, the exposure of LNCaP cells to 2-PMPA showed a dose-dependent effect with ~52% cell death at 200 nM (p < 0.001) and no quantifiable cell death in LNCaP-KD and PC-3 cells (Figure 4B). However, GB1107 by itself showed dose-dependent cytotoxic effect on all cell lines with ~60% cell death at 10 μM, the highest dose (Figure 4C). Reference: Cancers (Basel). 2022 May 30;14(11):2704. https://pubmed.ncbi.nlm.nih.gov/35681683/

In vivo activity:

Oral administration of a novel small molecule galectin-3 inhibitor GB1107 reduced human and mouse lung adenocarcinoma growth and blocked metastasis in the syngeneic model. Treatment with GB1107 increased tumor M1 macrophage polarization and CD8+ T-cell infiltration. Moreover, GB1107 potentiated the effects of a PD-L1 immune checkpoint inhibitor to increase expression of cytotoxic (IFNγ, granzyme B, perforin-1, Fas ligand) and apoptotic (cleaved caspase-3) effector molecules.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
