Low micromolar inhibitors of galectin-3 based on 3'-derivatization of N-acetyllactosamine.
(2002) In ChemBioChem 3(2-3). p.183-189- Abstract
- A strategy for generating potential galectin inhibitors was devised based on derivatization at the C-3′ atom in 3′-amino-N-acetyllactosamine by using structural knowledge of the galectin carbohydrate recognition site. A collection of 12 compounds was prepared by N-acylations or N-sulfonylations. Hydrophobic tagging of the O-3 atom in the N-acetylglucosamine residue with a stearic ester allowed rapid and simple product purification. The compounds were screened in a galectin-3 binding assay and three compounds with significantly higher inhibitory activities compared to the parent N-acetyllactosaminide were found. These three best inhibitors all carried an aromatic amide at the C-3′ position of the galactose moiety, which indicates that... (More)

These three best inhibitors all carried an aromatic amide at the C-3′ position of the galactose moiety, which indicates that favorable interactions were formed between the aromatic group and galectin-3. The best inhibitor had an IC50 value (4.4 μM) about 50 times better than the parent N-acetyllactosaminide, which implies that it has potential as a valuable tool for studying galectin-3 biological functions and also as a lead compound for the development of galectin-3-blocking pharmaceuticals.
