In order to find antiviral compounds with novel structures, geldanamycin and lamivudine with different antiviral mechanisms were conjunctively synthesized to acquire a new compound TC-GM, and the antiviral activity of TC-GM was measured. The antiviral activity against HIV-1 was examined by p24 antigen ELISA kit. The activity against HBV was examined by dotblot. The activity against HSV and CoxB virus was examined by CPE. TC-GM exhibited broad-spectrum antiviral activities similarly like geldanamycin. TC-GM inhibited the replication of different viruses, including HIV-1, HBV, HSV 1 and 2, CoxB6. TC-GM showed more potent inhibitory activity against HIV-1 and HBV than other detected virus.
