Ultrastructure of Melanin Formation in Curvularia sp., Alternaria sp., and Drechslera Sorokiniana

Proceedings, annual meeting, Electron Microscopy Society of America, 1977
(+)-Scytalone [3,4-dihydro-3,6,8-trihydroxy-l-(2Hj-naphthalenone] and 1,8-di- hydroxynaphthalene (DHN) have been proposed as intermediates of melanin synthesis in the fungiVerticillium dahliae(1, 2, 3, 4) andThielaviopsis basicola(4, 5). Scytalone is enzymatically dehydrated byV.

Alternaria brasiliensis sp. nov., a leaf pathogen on Phaseolus vulgaris

Mycopathologia, 2001
Alternaria brasiliensis sp. nov., was isolated from leaves of common bean, Phaseolus vulgaris L., showing punctiform non concentric leaf spots of brown color. Besides the symptomatological differences, the new Alternaria species presents distinct type of arrangement of conidia chain, body and beak size.

Aromatic polyketides from a caterpillar associated Alternaria sp.

Tetrahedron Letters, 2017
Five new aromatic polyketides, alternaphenols A-E (1-5), and two known compounds (6-7) were isolated from a liquid culture of Alternaria sp. (strain no. NF2198), a caterpillar associated fungus. Their structures were determined by extensive spectroscopic analysis and single crystal X-ray crystallography. Compounds 1-7 were evaluated for their cytotoxic

Biphenyl metabolites from the patchouli endophytic fungus Alternaria sp. PfuH1

Fitoterapia, 2020
Patchouli is a tropical medicinal and spice crop with high economic value, and the endophytic microorganism is also one of its important components and can provide new active compounds with medicinal use. In the present study, four new biphenyl compounds named 3-O-demethylaltenuisol (1), (-)-dialtenuisol (5) and (+)-dialtenuisol (6), and altertoxin VII

Cytotoxic Meroterpenoids from the Fungus Alternaria sp. JJY‐32

Chemistry & Biodiversity, 2020
AbstractTwo new meroterpenoids, tricycloalternarenes X and Y, together with one known meroterpenoid, tricycloalternarene I, were isolated from the fungus Alternaria sp. JJY‐32. The structures including absolute configurations were established by the comprehensive spectroscopic data, electronic circular dichroism (ECD) spectral analyses, and ...

Chrodrimanins U and V, meroterpenoids from an Alternaria sp.

Natural Product Research
Two new meroterpenoids, chrodrimanins U and V (1 and 2), and two known compounds 3-hydroxypentacecilide A (3) and chrodrimanin T (4) were obtained from the ascomycete fungus Alternaria sp. Structural characterisation was achieved through integrated spectroscopic techniques. The absolute configuration of each new meroterpenoid (1 and 2) was assigned via
