Abstract

The invention relates to sym-triazine derivative compounds containing sym-tetrazine rings and a preparation method thereof and belongs to the technical field of pharmaceutical synthesis and medicines. The sym-triazine derivative compounds containing sym-tetrazine rings provided by the invention are new sym-triazine derivative compounds containing sym-tetrazine rings with higher biological activity and a certain inhibition effect on tumor cells, and are synthesized from cyanuric chloride, substituted sym-tetrazine hydrazine and di-substituted ammonia used as raw materials by the synthesis method. The synthesis method has the advantages of readily available raw materials, simple and convenience process, easiness for operation and lower synthesis cost, and is suitable for industrial production. Through in-vitro test of the inhibition effect on the tumor cells, the sym-triazine derivative compounds containing sym-tetrazine rings provided by the invention have stronger inhibition effect onthe tumor cells, such as human fibrosarcoma, human breast cancer, human lung cancer, human colon cancer and other tumor cells.

Description

technical field [0001] The invention relates to a s-triazine derivative compound, in particular to a s-triazine derivative compound containing an s-tetrazine ring and a preparation method thereof, belonging to the technical field of drug synthesis and medicine. Background technique [0002] Compounds such as triazine derivatives have attracted extensive research by many scholars and researchers due to their wide range of biological activities, especially the advantages of s-triazine derivatives in antitumor activity. [0003] A novel 2-hydroxy-4,6-diamino-[1,3,5]triazine as reported by Baindur N. et al. in Journal of medicinal chemistry, 2005, 48(6), 1717-1720. compounds in which 2-hydroxy-4-benzo[d]thiazole-6-[benzyl(isopropyl)]-1,3,5-triazine-4,6-diaminop-tyrosine kinase The inhibition rate reached 0.018 μM (IC 50 ); another example is the 2,4,6-triaryl-1,3,5-triazine-2,4 reported by Arya, K. et al in Bioorganic & Medicinal Chemistry Letters, 2007, 17, 3298-3304. 6-tria...
