Problems solved by technology

This structure is roughly similar to the active centers of carbonic anhydrase CAI and CA II in the cytoplasm, and its functions are basically the same, but it also creates a great problem for designing highly selective CA IX inhibitors (Monti S.M., et al.Curr Med Chem, 2012, 19:821–830.)

Abstract

The invention discloses novel N-4-phenylsulfonamido--N'-1-desoxy-(2-desoxy-2-substituted-amino)-beta-D-glucopyransoylthiocarbamide compounds with the general formula disclosed in the specification, which have the activity of inhibiting carbonic anhydrase and further achieve the effect of resisting tumor metastasis and invasion. The compounds structurally have the three active segments sulfamine, substituted glucosamine and thiocarbamide, and the three active segments and Zn<2+> ions in the carbonic anhydrase form coordinate bonds, thereby inhibiting the catalytic activity of the enzyme and performing the function of resisting tumor metastasis and invasion. Thus, the compounds have application potential in the aspect of antitumor drugs. In the general formula, R is defined in the specification.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to N-4-benzenesulfonamide-N'-1-deoxy-(2-deoxy-2-substituted amino)-β-D-glucopyranosylthiourea compound and a preparation method thereof And medical use, be specifically related to novel N-4-benzenesulfonamido-N'-1-deoxy-(2-deoxy-2-substituted amino)-β-D-glucopyranosylthiourea compound and preparation method thereof and the inhibitory effect on carbonic anhydrase IX, and its application in the preparation of antitumor drugs. Background technique [0002] Carbonic anhydrases (Carbonic anhydrases, CAs) are ubiquitous in living organisms and are a class of zinc-containing metalloenzymes. Physiological processes are crucial. Among them, carbonic anhydrase IX (CA IX) is a transmembrane protein and has been identified as a tumor-associated protein. Except for certain expression in gastrointestinal mucosal tissue, it is almost not expressed in other normal tissues, but it is not expressed ...
