Abstract

The invention provides an aromatic amido replaced s-triazine compound. A 2-amino-1,3,5-triazine compound and a cyanogen compound are mixed and then a solvent is added, reaction is performed under theeffect of a copper catalyst, and reaction liquid posttreatment is performed to obtain the compound. According to the preparation method of the compound, reaction conditions are mild, raw materials areeasy to obtain, operation is convenient, the cost is low, and the compound has a wide industrial application prospect. The aromatic amido replaced s-triazine compound has certain anti-human osteogenic sarcoma cell activity and can be applied to preparation of an antitumor drug, especially to preparation of drugs for treating osteogenic sarcoma. A structural general formula of the compound is shown in the description.

Description

technical field [0001] The invention belongs to the field of pharmacy, and relates to an aromatic amide group-substituted s-triazine compound, a preparation method and application thereof. Background technique [0002] Triazine compounds have various biological activities such as anticancer, antibacterial, antimalarial, and herbicide. This type of compound is mainly prepared by the reaction of isothiocyanate, guanidine and amidine; or by multi-step reaction of bromobenzene, substituted aniline, diethylamine and cyanuric chloride. The above methods have disadvantages such as the use of highly toxic reagents, expensive catalysts or ligands, difficult control of reaction conditions, cumbersome steps, and poor yields, which are subject to certain limitations in the use process. Therefore, the preparation of novel arylamide-substituted s-triazine compounds has certain application value. Contents of the invention [0003] The present invention provides a new class of triazine ...
