By adopting methods of fluorescent quantitation PCR, fluorescent quantitation RT-PCR, HBV DNA quantitation, HBsAg quantitation, HBeAg quantitation, cccDNA quantitation, Northern blot, Southern blot, Western blot, immunohistochemistry, and the like in the research and using the maintenance dose within the treating dose range for a long time (30-60 days), supernatant HBV DNA HBsAg HBeAg cultured by HepG-2.2.15 cells can completely disappear, HBsAg, HBeAg, HBcAg, and the like in the cells are completely turned to be negative, HBV DNA is in a high inhibited state, HBV cccDNA is completely negative, fluorescent quantitation RT-PCR detection finds that the mRNA for expressing HBsAg and HBcAg antigens in the cells is completely negative, and in addition, the curative effect of the atabrine is 30 times that of lamivudine as a first-line drug for resisting HBV in current clinic. In order to illustrate the action mechanism of the atabrine and the pyronaridine as a drug belonging to the same kind with the atabrine, an HBV genome is divided into 3 segments which are respectively inserted into an Xb1 position on a luciferase report carrier PGL3, a multifunctional microplate reader detects and finds that the light production value of the luciferase is remarkably reduced, which shows that the molecules of the atabrine and the pyronaridine as a drug belonging to the same kind with the atabrine can be nonspecifically combined with the HBV DNA in the cells, thereby inhibiting the copying of the virus and ensuring that the HBV DNA content of the virus in cells copied by the filial generation is reduced till to disappear. The patent requires protecting the application of 3 linked benzyl structures (named as ethyleneimine) and radicals such as CH3O-,-NH-, CL-, and the like for resisting HBV virus in clinic.
