Description

TD139 is a novel high-affinity inhibitor of the galectin-3 carbohydrate binding domain with a Kd of 14 nM.

IC50 & Target

Kd: 14 nM (galectin-3)[1]

In Vitro

TD139 is a novel synthetic inhibitor of galectin-3. TD139 has high affinity for galectin-3 with a Kd of 14 nM and 10 nM for galectin-1, but low affinity for galectins 2, 4N, 4C, 7, 8N, or 9N[1].

In Vivo

In primary lung AECs TD139 reduces TGF-β1–induced β-catenin translocation to the nucleus, with most of the β-catenin remaining at the cell surface. TD139 blocks TGF-β1–induced β-catenin phosphorylation. A marked reduction in fibrosis and β-catenin activation accompanied by decreased galectin-3 expression is observed in the lungs of WT mice treated with TD139[1]. Pretreatment of WT C57BL/6 mice with TD139 leads to the attenuation of liver injury and milder infiltration of IFNγ- and IL-17- and -4-producing CD4(+) T cells, as well as an increase in the total number of IL-10-producing CD4(+) T cells and F4/80(+) CD206(+) alternatively activates macrophages and preventes the apoptosis of liver-infiltrating MNCs[2].

Animal Administration
[2]

TD139 is prepared in saline.

Mouse: The susceptibility to Con A-induced hepatitis in galectin-3-deficient mice is tested and the effects of pretreatment with a selective inhibitor of Gal-3 (TD139) in wild-type(WT) C57BL/6 mice are analyzed, as evaluated by a liver enzyme test, quantitative histology, mononuclear cell (MNC) infiltration, cytokine production, intracellular staining of immune cells, and percentage of apoptotic MNCs in the liver[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
