Paragraph 0317; 0318; 0320; 0321; 0322, (2019/02/25)
The invention relates to compounds of antiviral novel nucleoside reverse transcriptase inhibitors, pharmaceutical compositions containing the compounds, and preparation and use of the compounds, and particularly discloses fused pyrimidine compounds shown in formula (I) and the pharmaceutical compositions containing the compounds, pharmaceutically acceptable salts, stereoisomers, solvates, hydrates, crystal forms, prodrugs or isotope derivatives. The compounds can be used for treating and/or preventing viral infectious diseases, such as human immunodeficiency virus (HIV) and hepatitis B virus (HBV). The formula (I) is shown in the specification.
Puerarin derivative and preparation method and application thereof
-
Paragraph 0066; 0067, (2019/04/06)
The invention relates to a puerarin derivative and a preparation method and an application thereof. The puerarin derivative is prepared through six steps of reactions by taking puerarin and L-alanineisopropyl ester hydrochloride as main raw materials. The puerarin derivative not only has good water solubility, but also has good anti-platelet aggregation action and can be used for preparing anti-platelet aggregation drugs. In addition, the reaction conditions of the reactions for preparing the puerarin derivative are mild, and the synthetic method is simple.
