The Trifluridine novel crystal form is good in stability and solubility; the preparation method is relatively good in reproducibility, the operation is simple and convenient, the period is short, the cost is low, damage to the environment and staff is little, and the preparation method is suitable for industrial large-scale production, and has quite important application value in medicine preparation.

Description

technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and specifically relates to a new crystal form of Trifluridine, a preparation method and a pharmaceutical composition thereof. Background technique [0002] Trifluridine (Trifluorothymidine, referred to as FTD or TFT) is also known as trifluorothymidine, trifluorothymidine, 5-trifluoro-2'-deoxythymidine (5-trifluoro-2'-deoxythymidine), 5-trifluoromethyl -2′-Deoxyuridine (5-trifluromethyl-2′-deoxyuridine), α,α,α-trifluorouridine (α,α,α-trifluoro-Uridine), its molecular formula is C 10 h 11 f 3 N 2 o 5 , the chemical structural formula is as follows: [0003] [0004] People have paid attention to the thymidine structural analog Trifluridine for many years, because of its antitumor and antiviral activities, people have done a lot of research on it in the field of medicine. Trifluridine is a thymidylate synthase (TS) inhibitor that interferes with the production of th...
