Screening for anti-influenza virus activity in compounds isolated from Streptomyces sp. RI18, which was isolated using the membrane filter method, uncovered a novel compound, JBIR-68 (1), which contains a unique skeleton. Its structure was established by extensive NMR and MS analyses. In addition, 1 was synthesized to confirm the configuration of its sugar moiety. Compound 1 inhibited influenza virus growth in plaque assays.
