A New α-Pyrone Derivative from Endophytic Fungus Pestalotiopsis microspora
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...
متن کاملPhotinides A-F, cytotoxic benzofuranone-derived gamma-lactones from the plant endophytic fungus Pestalotiopsis photiniae.
Photinides A-F (1-6), six new unique benzofuranone-derived gamma-lactones, have been isolated from the crude extract of the plant endophytic fungus Pestalotiopsis photiniae. The structures of these compounds were elucidated primarily by NMR spectroscopy, and their absolute configurations were assigned by application of the CD excitation chirality method. Compounds 1-6 displayed modest cytotoxic...
متن کاملDihydroberkleasmin A: a new eremophilane sesquiterpenoid from the fermentation broth of the plant endophytic fungus Pestalotiopsis photiniae.
Dihydroberkleasmin A (1), a new ester-substituted sesquiterpenoid related to the eremophilane class, together with the known compound berkleasmin C (2), were isolated from the fermentation broth of the plant endophytic fungus Pestalotiopsis photiniae. The structure of dihydroberkleasmin A (1) was elucidated by extensive spectroscopic analysis. The stereochemistry was assigned by comparison of t...
متن کاملNew furanones from the plant endophytic fungus Pestalotiopsis besseyi.
Pestalafuranones A-E (compounds 1-5), five new 2(5H)-furanones, have been isolated from cultures of an isolate of Pestalotiopsis besseyi. The structures of these compounds were elucidated mainly by analysis of their NMR spectroscopic data and HRESIMS experiments. Pestalafuranones A-C (compounds 1-3) displayed weak inhibitory effects against HIV-1 replication in C8166 cells, whereas pestalafuran...
متن کاملAntifungal metabolites from the plant endophytic fungus Pestalotiopsis foedan.
Pestafolide A ( 1), a new reduced spiro azaphilone derivative, and pestaphthalides A ( 2) and B ( 3), two new isobenzofuranones, have been isolated form solid cultures of an isolate of Pestalotiopsis foedan. The structures of these compounds were determined mainly by analysis of their NMR spectroscopic data. The relative configuration of 1- 3 was assigned by analysis of (1)H NMR J-values and NO...
