title: Antileukemic compounds derived by chemical modification of macrocyclic trichothecenes. 2. Derivatives of roridins A and H and verrucarins A and J.
abstract: Various 8 beta-hydroxy, 16-hydroxy, and 9 beta,10 beta-epoxy derivatives of roridins A and H and verrucarins A and J have been prepared and tested in vivo against P388 mouse leukemia. The 9 beta,10 beta-epoxy derivatives and 16-hydroxy derivatives consistently exhibit very high activity. The 8 beta-hydroxy-9 beta,10 beta-epoxy and 16-hydroxy-9 beta,10 beta-epoxy derivatives of verrucarin A and roridin A exhibit extraordinary activity against P388. The 8 beta-hydroxy-9 beta,10 beta-epoxy and 16-hydroxy-9 beta,10 beta-epoxy derivatives of verrucarin A and roridin A exhibit extraordinary against P388.
