LEAVES OF Erythrina speciosa ANDREWS.In vitro bioassays with leave extracts of Erythrina speciosa showed promising activity against Trypanosoma cruzi.From the flowers of E. speciosa two alkaloids were isolated: erysotrine and erythartine.The leaves furnished one alkaloid, nororientaline.The structures were determined on the basis of spectroscopic evidence.This is the first report about the investigation of alkaloids in flowers and leaves of this species, as well the first report of nororientaline occurrence in this plant.

ANTIFUNGAL COMPOUNDS OF Xylaria sp., AN ENDOPHYTIC FUNGUS ISOLATED FROM Palicourea marcgravii (RUBIACEAE).Five compounds, 2-hexyl-3-methyl-butanodioic acid (1), cytochalasin D (2), 7-dechlorogriseofulvin (3), cytochalasin B (4) and griseofulvin (5), have been isolated from the endophytic fungus Xylaria sp., and their structures were elucidated on the basis of spectroscopic data.In the bioautography assay against Cladosporium cladosporioides and Cladosporium sphaerospermum, compounds 1 and 2 were found to be active while compounds 3, 4 and 5 did not show antifungal activity.

Griseofulvin, Diketopiperazines and Cytochalasins from Endophytic Fungi Colletotrichum crassipes and Xylaria sp., and Their Antifungal, Antioxidant and Anticholinesterase Activities

Journal of the Brazilian Chemical Society (2018)

Vanessa Mara Chapla Maria Luiza Zeraik Mariana Carrara Cafêu Geraldo Humberto Silva Alberto José Cavalheiro

One new natural product, 1-phenylethyl-O-α-L-rhamnopyranoside, together with eight known diketopiperazines and two benzene derivatives were isolated from the endophytic fungus Colletotrichum crassipes, whereas six known compounds including two griseofulvins, three cytochalasins and one dihydroisocoumarin were produced from the endophyte Xylaria sp., both endophytic fungi are associated with leaves of Casearia sylvestris.Cyclo(D)-Pro-(D)-Phe, N-(2-phenylethyl)acetamide and 5-carboxy-6-hydroxy-3-methyl-3,4-dihydroisocoumarin exhibited potent antifungal activity against Cladosporium cladosporioides and C. sphaerospermum.The compounds cyclo(D)-Pro-(D)-Phe, griseofulvin, cytochalasin B and cytochalasin D exhibited antioxidant activity, and the compounds cyclo(D)-Pro-(D)-Phe, cytochalasin B and cytochalasin C showed potent acetylcholinesterase (AChE) inhibition.In addition, this is the first report on the isolation of secondary metabolites from two endophytic fungal strains, associated with Casearia sylvestris.
