Three new epipolythiodioxopiperazines, chaetocochins A (1), B (2), and C (3), along with dethio-tetra (methylthio) chetomin (4) and chetomin (5), were isolated from the ethyl acetate extract of the…
Nitrogen-containing dihydro-β-agarofuran derivatives from Tripterygium wilfordii.
Tripterygiumine Q (26) exhibited immunosuppressive activity against human peripheral mononuclear cells with an IC50 value of 8.67 μM and showed no cytotoxicity, even at 100 μM, indicating that 26 may represent a novel scaffold for the development of new Immunosuppressants.
Sesterterpenoids, terretonins A-D, and an alkaloid, asterrelenin, from Aspergillus terreus.
Four new sesterterpenoids, terretonins A-D (1-4), and a new alkaloid, asterrelenin (5), together with five known compounds, were isolated from the ethyl acetate extract of a solid-state fermented…
Indole Alkaloids from Chaetomium globosum.
Three new epipolythiodioxopiperazines, chaetocochins G-I (5-7), were identified by the combination of UPLC and mass spectrometric analysis and showed antibacterial activities against Bacillus subtilis, but not against Gram-negative bacterium (Escherichia coli).
Four New Alkaloids, Brevianamides O-R, from the Fungus Aspergillus versicolor
Four new alkaloids, brevianamides O - R (1-4, resp.), were isolated from the AcOEt extract of the solid-state fermented rice culture of the fungus Aspergillus versicolor. Their structures were…
