Ring (リング , Ringu ) is a Japanese mystery horror novel by Koji Suzuki first published in 1991, and set in modern-day Japan.
 It was the basis for a 1995 film (""), a television series (""), a film of the same name (1998's "Ring"), and two remakes of the 1998 film: a South Korean version ("The Ring Virus"), an American version ("The Ring"), and The Ring's sequel, Rings.
Lactimidomycin is a glutarimide antibiotic derived from the bacteria "Streptomyces amphibiosporus".
 It has antifungal, antiviral and anti-cancer properties, acting as a direct inhibitor of protein translation in ribosomes. 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.
 As lactimidomycin is a natural product containing an unusual unsaturated 12-membered lactone ring, it has been the subject of numerous total synthesis approaches.
