- Carboxamide and amine compounds as well as preparation method and applications thereof
-
The invention discloses carboxamide and amine compounds as well as a preparation method and applications thereof as stable and efficient antioxidation sterilizers, belonging to the technical field of invention and preparation of novel antioxidation sterilizer compounds. All the compounds disclosed by the invention are stable antioxidation sterilizers which have different stable structures formed by connecting carboxamide and amine bonds, and meanwhile, products having different lengths of aliphatic chains are produced by adjusting an n value, such that the products can be completely matched with a specific high polymer material in performance, the problems that a micromolecular stabilizer is volatilized fast, easily drawn from high polymer materials and the like are solved, the service life of the material is greatly prolonged, and the carboxamide and amine compounds have relatively strong and durable high polymer material protection performance. Compared with the prior art, the stable high polymer antioxidants disclosed by the invention have relatively high capabilities of resisting hydrolysis, acidolysis, alkaline hydrolysis, degradation in a chemical pollution environment, and these performances provides a new better antioxidant selection range for the development of modern new materials. Furthermore, this kind of carboxamide and amine compounds also have the characteristics of difficulty in volatilization, good matching performance with high polymer materials, good high polymer protection capability, good environmental performance, attractive appearance and durability, low cost and the like.

- Esters of Thiodiglycollic and Thiodipropionic Acids and 2,5-Dicarboxy-3,4-dihydroxythiophene as Potential Slow Acting Anticancer Agents
-
A series of esters of thiodiglycollic and thiodipropionic acids and 2,5-dicarboxy-3,4-dihydroxythiophene have been synthesised with a view to testing their anticancer properties.The esters, as against parent acids are expected to have a prolonged effect.
