Oxime-containing precursors, 2,3- secointermediates and five-membered ring A products of cyclizations were screened for in vitro antiviral activity against enveloped viruses - influenza A virus and human immunodeficiency virus type I (HIV-1). Lupane ketoxime and the 2,3-secolupane C-3 aldoxime which possess antiviral activities against both influenza A virus (EC50 12.9-18.2 μM) and HIV-1 (EC50 0.06 μM) were the most promising compounds.
