  ABSTRACT: Seven lanostane triterpenoids, ganorbiformins A-G, together with twelve known compounds, were isolated from cultures of the mushroom fungus Ganoderma orbiforme BCC 22324. Ganorbiformin A is an unusual rearranged analog, whereas the other compounds share the same lanostane skeleton with known ganoderic acids. The C-3 epimer of ganoderic acid T also exhibited significant antimycobacterial activity against Mycobacterium tuberculosis H37Ra (MIC 1.3μM).

  ABSTRACT: A novel 20-norpimarane glucoside, xylopimarane (1), together with the known sphaeropsidin C (2) and clonostachydiol (3), was isolated from the fungus Xylaria sp. BCC 4297. Compound 1 exhibited cytotoxicity to cancer cell lines KB, MCF-7, and NCI-H187 with respective IC(50) values of 1.0, 13, and 65 μM.

  ABSTRACT: Six new oblongolides, W1, W2, X, Y, and Z (1-3, 6, 7) and 2-deoxy-4alpha-hydroxyoblongolide X (4), and the known compounds oblongolide (8), oblongolides T, C, and Q (5, 9, 10), and (-)-5-methylmellein were isolated from the endophytic fungus Phomopsis sp. BCC 9789. Compound 7 showed anti-HSV-1 activity (IC50=14 microM) and cytotoxic activities against KB, BC, NCI-H187, and nonmalignant (Vero) cell lines with respective IC50 values of 37, 26, 32, and 60 microM. Cytotoxic activity against the BC cell line was also observed for compound 6, with an IC50 value of 48 microM.

  ABSTRACT: Three new isocoumarin glucosides (1, 3, and 4), 6,8-dihydroxy-3-methylisocoumarin (2), and 6,8-dihydroxy-3-hydroxymethylisocoumarin (5) were isolated from the scale insect pathogenic fungus Torrubiella tenuis BCC 12732. Structures of these compounds were elucidated using NMR spectroscopic and MS spectrometric analyses. Compound 5 exhibited moderate anti-HSV-1 and antimycobacterial activities with IC(50) and MIC values of 50 and 25 microg/mL, respectively.
