| structure-activity relationship studies of putaminoxins and pinolidoxins: phytotoxic nonenolides produced by phytopathogenic phoma and ascochyta species. | putaminoxin and pinolidoxin, two structurally related nonenolides, isolated respectively from organic extracts of phoma putaminum and aschochyta pinodes cultures, together with some of their natural analogs and synthetic derivatives, were used in a structure-activity relationship study. their phytotoxic, antifungal and zootoxic activities were assayed with the aim to find compounds with potential herbicidal properties. the strongest phytotoxic compounds proved to be putaminoxin and pinolidoxin, ... | 1998 | 10398515 |
