Description

Galectin-3-IN-6 (Compound 12) is a human and murine galectin-3 (Gal-3) inhibitor, with an IC50 of 12 nM against human galectin-3, an IC50 of 12.6 nM against mutant murine galectin-3 (V160A), and a Kd of 13 nM for human galectin-3, as well as oral bioavailability. Galectin-3-IN-6 reduces the levels of liver fibrosis markers type I collagen and α-smooth muscle actin in mouse models of acute liver injury and fibrosis. Galectin-3-IN-6 can be used for the research of acute liver injury and fibrosis[1].

In Vitro

Galectin-3-IN-6 (compound 12) potently inhibits human galectin-3 in an asialofetuin competitive binding assay with an IC50 of 12 nM[1].
Galectin-3-IN-6 (compound 12) binds to human galectin-3 with a Kd of 13 nM, as measured by Biacore analysis[1].
Galectin-3-IN-6 (compound 12) exhibits metabolic stability in human and mouse liver microsomes with intrinsic clearance values of 29 and 20 μL/(min*mg), respectively[1].
Galectin-3-IN-6 (compound 12) forms a stable complex with human galectin-3, as confirmed by X-ray crystallography (PDB ID: 8RMT), with its hydroxy group replacing the conserved water in the lectin's carbohydrate recognition domain[1].
Galectin-3-IN-6 (compound 12) binds to V160A mutant mouse galectin-3 with a Kd of 12.6 nM, identical to its inhibitory potency against human galectin-3[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
