Legonmycins are a group of chemical compounds that belong to the pyrrolizidine family of naturally occurring alkaloids. Discovered by a joint team of researchers from University of Ghana, University of Aberdeen, and Wuhan University, the compounds were isolated from Streptomyces microorganisms in Legon, a suburb of Accra, Ghana. Laboratory syntheses of legonmycin A and legonmycin B have been reported.
