Abstract

The invention discloses a carbohydrate derivant, complex compound and making method with coordination Pt complex compound of cancer resistant, which is characterized by the following: reacting primary diamine 2,3-anhydride-alpha-D-manna pyran glycoside to obtain the diamine; making the diamine and Pt salt to obtain the Pt complex compound of coordinated nitrogen atom; making single Pt complex compound coordinated by diamine and diPt complex compound coordinated by bridged diamine and alkali additional salt; fitting for the drug composition to treat cancer.

Description

technical field [0001] The present invention relates to a class of carbohydrate derivatives, complexes and preparation methods thereof, in particular to a class of carbohydrate-derived diamine compounds and their coordinated platinum complexes with anticancer effects, including platinum complexes The structure of the ingredients of the pharmaceutical composition and its preparation. technical background [0002] Cisplatin (cis-[PtCl 2 (NH 3 ) 2 ]) is an important class of clinical drugs for the treatment of human cancer (Inorg.Chim.Acta, 1992, 198-200, 873), but its high toxicity, drug resistance and other issues force people to look for new compounds containing nitrogen atoms. platinum complexes. Drugs such as Carboplatin and JM216, which were invented and applied clinically, significantly reduced the toxic and side effects, but also greatly reduced the drug activity (Plat.Met.Rev.1989, 33, 162; Inorg.Chem.1995, 34, 1015) . In view of the fact that carbohydrates are i...
