Species of Pestalotiopsis were mainly introduced as endophytes, plant pathogens or saprobes from various hosts. In this study, ten strains isolated Ficus macrocarpa, Phoebe zhennan and Spatholobus suberectus in China. Based on multilocus phylogenies the internal transcribed spacer (ITS), partial translation elongation factor 1-alpha gene (tef1α) beta-tubulin (tub2), conjunction with morphologic...

A new α-pyrone derivative 1, along with four known congeners 2, 3, 4 and 5, were isolated from the solid-substrate fermentation medium of the endophytic fungus Pestalotiopsis microspore isolated from the branch of Taxus chinensis. Their structures and relative configurations were elucidated by extensive spectroscopic analysis. The cytotoxic activities of the isolated α-pyrone derivatives agains...

Several species of mitosporic fungi collected from Guilan and Mazandaran provinces were examined and as a result, four species viz.,Pestalotiopsis acaciae (on Diospyros lotus), Prathigada condensata (on Gleditschia caspica), Stigmella effigurata (on Castanea sativa), Teratosperma uniappendiculatum (on perthecia of Cryphonectria parasitica) are reported as new records for Iranian mycobiota. More...

Here we describe the biotransformation of clovane derivatives by filamentary fungi Pestalotiopsis palustris and Penicillium minioluteum, and the application of the latter to the synthesis and determination of the absolute configuration of rumphellclovane A (2). Methoxyclovanol (1), a growth inhibitor of the phytopathogen Botrytis cinerea, is metabolised by P. palustris to yield rumphellclovane ...

Four new ambuic acid derivatives (1-4), and four known derivatives (5-8), were isolated from the solid culture of a plant pathogenic fungus Pestalotiopsis neglecta. Their structures were elucidated by extensive NMR experiments. The absolute configuration of the C-16 secondary alcohol in 1 was deduced via the CD data of the in situ formed [Rh2(OCOCF3)4] complex with the acetonide derivative of 1...

A Pestalotiopis sp. was isolated from the trunk bark of Pinus taeda. The fungus was cultivated in liquid medium and produced three highly oxygenated caryophyllene sequiterpene derivatives, named pestalotiopsolide A, taedolidol and 6-epitaedolidol, respectively. The sesquiterpenes were isolated by silica gel based chromatographic procedures and their structures were elucidated by NMR spectroscop...

PURPOSE To report the isolation of Pestalotiopsis clavispora from the cornea of a patient with recurrent keratitis. CASE REPORT A 73-year-old male gardener presented with conjunctival injection and an oval infiltrate with feathery margins in the temporal half of the cornea in the right eye. His ocular history in the right eye included cataract surgery, five episodes of herpes simplex keratiti...

Five new polyketide-terpene hybrid metabolites (1-5) with highly functionalized groups, together with six known derivatives (6-11), were isolated from the endolichenic fungus Pestalotiopsis sp. Their structures were elucidated by extensive NMR experiments including 1H, 13C, HMQC, COSY, and HMBC. The relative configurations of the new compounds were determined by analysis of coupling constants a...
