Paragraph 0029-0030, (2021/06/26)
The invention belongs to the technical field of medicines, and relates to a preparation method and medical application of an N1-aryl sulfanilamide-N4-beta-D-glucopyranose diamide compound. The compound is shown in a general formula (I), substituent groups are described in the specification, and the compound shown in the general formula (I) and an optical active body, a diastereoisomer and a pharmaceutically acceptable salt thereof are applied to preparation of anti-tumor drugs. Based on pharmacophore characteristics and subcellular localization of CA IX and XII, a selective CA IX and XII inhibitor is designed and synthesized, polyhydroxy high-polarity glucose is selected as a tail end, a classical pharmacophore aryl sulfanilamide fragment of a targeted CAs active center is introduced through a flexible aliphatic chain and a rigid aromatic structure, the overall structure can selectively inhibit catalytic activity of extracellular CA IX and XII, an anti-tumor effect is achieved, and therefore, the compound has a good application prospect.

A series of saccharide-modified thiadiazole sulfonamide derivatives has been designed and synthesized by the “tail approach” and evaluated for inhibitory activity against carbonic anhydrases II, IX, and XII. Most of the compounds showed high topological polar surface area (TPSA) values and excellent enzyme inhibitory activity. The impacts of some compounds on the viability of HT-29, MDA-MB-231, and MG-63 human cancer cell lines were examined under both normoxic and hypoxic conditions, and they showed certain inhibitory effects on cell viability. Moreover, it was found that the series of compounds had the ability to raise the pH of the tumor cell microenvironment. All the results proved that saccharide-modified thiadiazole sulfonamides have important research prospects for the development of CA IX inhibitors.
