The present invention relates to novel compounds, the use of said compounds as a medicament as well as for the manufacture of a medicament for treatment of disorders relating to the binding of galectin to receptors in a mammal. Said galectin is preferably a galectin-3.

Administration of low molecular weight (10,000-20,000 Daltons, or lower) pectins, particularly modified citrus pectins (MCP), like PectaSol-C reduces galectins-3 levels in vivo. Reduction of galectin-3 levels by MCP inhibits inflammation, inhibits fibrosis formation in organs and tissues, and inhibits cancer formation, progression, transformation and metastases. The reduction in circulating, serum and cellular galectin-3, inherently resulting from the administration of MCP, provides benefit over a spectrum of biological conditions, as evidenced by in vivo trials.

The invention relates to a preparation method and application of an electrochemical sensor for detecting a blood concentration level of an insulin sensitivity reduction early diagnosis biomarker, namely galectin-3 (Gal-3), causing type II diabetes, and belongs to the technical field of electrochemical detection. The preparation method is characterized by comprising the following steps: respectively synthesizing an N-GNRs-Fe-MOFs@AuPNs sensor substrate modified nano composite material and an AuPt-MB nano composite signal material, enabling a detection antibody capable of being in specific binding to the Gal-3 to be mixed with the AuPt-MB composite material so as to prepare a biological signal probe; conjugating a Gal-3 specific capture antibody on a substrate platform modified by the N-GNRs-Fe-MOFs@AuPNs composite material so as to conveniently and specifically capture a target Gal-3; finally, performing specific binding on the Gal-3 as well as the detection antibody and the capture antibody, thereby obtaining the electrochemical sensor for detecting the blood concentration level of the Gal-3. The sensor is successfully used for detecting the Gal-3 in serum. The electrochemical sensor disclosed by the invention has the advantages of being high in sensitivity, high in specificity, rapid in detection and convenient. An early diagnostic basis is provided for insulin resistance causing the type II diabetes.
