Administration of the antiviral agent T-1105 fully protects pigs from foot-and-mouth disease infection.

Foot-and-mouth disease (FMD) is a contagious disease affecting cloven-hoofed animals. Its transmissibility and antigenic variety make this disease difficult to control. Antiviral agents are expected to have an immediate effect that is independent of viral antigenicity; thus, they can serve as effective tools for inhibiting the spread of the causative agent, the FMD virus (FMDV), from infected animals.

Total syntheses of (±)-fawcettimine, (±)-fawcettidine, (±)-lycoflexine, and (±)-lycoposerramine-Q.

The total syntheses of four fawcettimine-related Lycopodium alkaloids, (±)-fawcettimine, (±)-fawcettidine, (±)-lycoposerramine-Q, and (±)-lycoflexine, were completed in a highly stereoselective manner. The Pauson-Khand reaction of 4-methylidene-6-siloxyoct-1-en-7-yne followed by regio- and stereoselective hydrogenation led to the short-step preparation of the bicyclo[4.3.
