title: Synthesis and anti-influenza virus activity of dihydrofuran-fused perhydrophenanthrenes with a benzyloxy-type side-chain.
abstract: As one of our ongoing research project concerning development of a novel anti-influenza virus agent, dihydrofuran-fused perhydrophenanthrenes were derivatized by means of Williamson ether synthesis and Suzuki-Miyaura cross coupling reactions. Newly synthesized compounds were subjected to evaluation of anti-influenza virus activity using influenza A/Aichi/2/68 (H3N2 subtype) virus strain by a plaque titration method. These investigations revealed that incorporation of benzyl-type ether substituents was effective for exerting the inhibition activity of influenza virus proliferation.
