松香基氮杂环抗病毒化合物的设计合成及构效关系研究

Natural products have the advantages of abundant, activity, easy degradation, high efficiency and low toxicity, so the modified compounds from natural products have become an important source in the screening of antiviral compounds. In this proposal, natural products rosin and its derivatives are chosen as the main raw materials, aldehyde, amino and carbonyl groups are modified to the tricyclohydrophenanthrene skeleton of rosin firstly. Then the N-heterocyclic structure such as pyridine, pyrimidine, tetrahydroquinoline and pyrrole are further constructed. IR, NMR and MS are used to identify the structures of the rosin-based N-heterocyclic compounds. Investigating the antiviral activity of the N-heterocyclic derivatives, with the calculation of quantum chemistry software such as Gauss View, Gaussian 09, Ampac and Codessa, the quantitative structure-activity relationships (QSAR) model between rosin-based N-heterocyclic compounds and the antiviral activity would be established. This QSAR model would reveal the structure-activity relationships of rosin-based N-heterocyclic compounds. On the basis of above research, related conclusions would provide a guidance for the further synthesis of rosin-based antiviral compounds and open a new way for the high value utilization of rosin.
