Lactimidomycin is a glutarimide antibiotic derived from the bacteria Streptomyces amphibiosporus.[1][2] It has antifungal, antiviral and anti-cancer properties, acting as a direct inhibitor of protein translation in ribosomes.[3][4][5] Antiviral activity is seen against a variety of RNA viruses including flaviviruses such as dengue fever, Kunjin virus and Modoc virus, as well as vesicular stomatitis virus and poliovirus.[6] As lactimidomycin is a natural product containing an unusual unsaturated 12-membered lactone ring, it has been the subject of numerous total synthesis approaches.[7][8][9][10]
