Provided is a lactam compound, a tautomer, a stereoisomer, a racemate, a nonequal mixture of enantiomers, a geometric isomer, a solvate, a pharmaceutically acceptable salt thereof, or a solvate of the salt of the compound, and a pharmaceutical composition containing the compound. Also provided are the use of such compounds and their pharmaceutical compositions as drugs, especially as antiviral drugs.

Lactam compound, preparation method and use thereof

The present invention provides alkaloids with formula I, II, III, IV, or V and their pharmaceutically acceptable salts, their preparation and their uses as antivirus drugs, for example, for treatment of HSV-1 infection. The alkaloids with formula I were isolated from the fermentation of marine fungussp. (TA01-33) by means of column chromatography, such as positive phase silica gel column chromatography, etc. Alkaloids with formula II, III, IV and V were semisynthesized from compounds with formula I.

Alkaloids and their preparation and application as anti-HSV-1 agents

Provided herein are quinolinone derivatives and their uses as antiviral drugs, for example, for treatment of HSV-1 infection. Also provided herein are pharmaceutically acceptable compositions comprising the quinolinone derivatives and the uses of the composition in the treatment of diseases caused by HSV-1 virus.
