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 previous literature data. This is the first report of the isolation of alkaloids (1-9) from Talaromyces genus. In the next step, all compounds were screened for their anti-monoamine oxidase, anti-acetylcholinesterase, antibacterial and antitumor activities. Compound 11 showed moderate anti-monoamine oxidase activity with IC₅₀ value of 61 μM; compounds 3, 4, 8 showed weaker anti-acetylcholinesterase activity; compounds 1, 3, 4, 7, 8, 9 showed moderat
