Abstract
Besides the known imide ritigalin (9), six new phenethyl/styrylamine-derived amides isolated from lipophilic leaf extracts of Glycosmis cf. mauritiana, Glycosmis cf. cyanocarpa, and Glycosmis crassifolia displayed pronounced antifungal and/or insecticidal activity against Cladosporium herbarum and Spodoptera littoralis, respectively, the methylthiocarbonic acid derivatives niranin (1), dehydroniranin A (2), and dehydroniranin B (3) as well as the isovaleric and senecioic acid derivatives thalebanin B (4), dehydrothalebanin B (5), and dehydrothalebanin A (6).
