    Journal: J Med Chem; 1994 Sep 02; 37(18):2896-902. PubMed ID: 8071937.
    Abstract:
    The synthesis of some spiro[cyclopropane-1,2'-adamantan]-2-amines and methanamines and some spiro[pyrrolidine-2,2'-adamantanes] is described. The title compounds were evaluated against a wide range of viruses (influenza A, influenza B, parainfluenza 3, RSV, HSV-1, TK- HSV-1, HSV-2, vaccinia, vesicular stomatitis, polio 1, coxsackie B4, sindbis, semliki forest, Reo 1, HIV-1, and HIV-2), and some of them (compounds 6b, 6c, 9a, 16a, 16b, and 17) inhibited the cytopathicity of influenza A virus at a concentration significantly lower than that of amantadine and also significantly lower than the concentrations at which they proved cytotoxic to the host cells. None of the new aminoadamantane derivatives was active against influenza B virus or any of the other viruses tested, which points to their specificity as anti-influenza A virus agents.
