Thielavialides A–E, Nor-Spiro-azaphilones, and a Bis-spiro-azaphilone from Thielavia sp. PA0001, An Endophytic Fungus Isolated from Aeroponically Grown Physalis alkekengi†

Four new nor-spiro-azaphilones, thielavialides A-D (1- 4), a new bis-spiro-azaphilone, thielavialide E (5), together with pestafolide A (6), were isolated from the endophytic fungal strain, Thielavia sp. PA0001, occurring in the healthy leaf tissue of aeroponically grown Physalis alkekengi. The structures and relative configurations of 1-5 were established on the basis of their MS and NMR data....

Antibacterial Azaphilones from an Endophytic Fungus, Colletotrichum sp. BS4.

Three new compounds, colletotrichones A-C (1-3), and one known compound, chermesinone B (4a), were isolated from an endophytic fungus, Colletotrichum sp. BS4, harbored in the leaves of Buxus sinica, a well-known boxwood plant used in traditional Chinese medicine (TCM). Their structures were determined by extensive spectroscopic analyses including 1D and 2D NMR, HRMS, ECD spectra, UV, and IR, as...

A novel tricyclic polyketide and its biosynthetic precursor azaphilone derivatives from the endophytic fungus Dothideomycete sp.

Azaphilone derivatives 1 and 2 and a novel tricyclic polyketide 3, together with a known azaphilone, austdiol (4), were isolated from the endophytic fungus Dothideomycete sp., which was isolated from a Thai medicinal plant, Tiliacora triandra. Compound 3 is the first polyketide having a tricyclic 6,6,6 ring system, which is similar to that of a terpenoid skeleton. The absolute configurations of...

A novel alkaloid serantrypinone and the spiro azaphilone daldinin D from Penicillium thymicola.

The novel quinazoline metabolite serantrypinone (1) has been isolated from an isolate of the microfungus Penicillium thymicola together with daldinin D (2), a new peracetylated spiro azaphilone derivative. The structures of 1 and 2 were elucidated by analysis of spectroscopic data, including 2D NMR, and comparison with literature data.

Secondary metabolites and biological activities of Talaromyces sp. LGT-2, an endophytic fungus from Tripterygium wilfordii

Abstract In the present study, eleven compounds (1-11) including nine alkaloids (1-9), one triterpenoid saponin (10) and one formamide (11) were isolated from Talaromyces sp. LGT-2, an endophytic fungus from Tripterygium wilfordi. Their structures were determined based on NMR and ESI-MS spectral data, as well as comparing with previous literature data. This is the first report of the isolation ...
