Two new alkaloids, picrasidines M (II) and P (III), have been isolated from the root-bark of Picrasma quassioides BENNET. The structure of picrasidine L has been revised from 3-methyl-canthin-2, 6-dione to 3-methylcanthin-5, 6-dione (I). The structures were determined on the basis of spectral analysis and chemical evidence.
Zanthoxylum chiloperone var. angustifolium was investigated. Alkaloids 1-3 from the canthin-6-one series were characterized. Derivatives 7-28 were prepared by hemisynthesis or total synthesis. All compounds were tested for in vitro antifungal activities against five pathogenic fungal strains. Analogues of canthin-6-one did not show better antifungal activities.
