Abstract
Colossolactone J (1), an undescribed lanostane triterpenoid was isolated from a natural fruiting body of Ganoderma colossus using silica gel column chromatography and preparative HPLC. Its structure was elucidated on the basis of the spectroscopic method. The absolute configuration was determined by the combination of the modified Mosher's method and detailed NMR data analysis.

Abstract
Antitubercular lanostane triterpenoids isolated from mycelial cultures of the basidiomycete Ganoderma australe were structurally modified by semisynthesis. One of the synthetic compounds, named GA003 (9), showed more potent activity against Mycobacterium tuberculosis H37Ra than the lead natural lanostane (1). GA003 was also significantly active against the virulent strain (H37Rv) as well as extensively drug-resistant tuberculosis strains.

Abstract
Three previously undescribed limonoids, fulvifomins A-C, together with two known compounds, 6-deoxydetigloyl-swietenine acetate and methyl angolensate, were isolated from fruiting bodies of the wood-rot fungus Fulvifomes xylocarpicola (Hymenochaetaceae), growing on the mangrove tree Xylocarpus granatum (Meliaceae). The structures were elucidated on the basis of NMR spectroscopic and mass spectrometry data, and X-ray crystallographic analysis (for fulvifomin A). A number of similar limonoids have been isolated from higher plants of the family Meliaceae, including X. granatum. The present study represents a unique evidence that the associated basidiomycete also contains these limonoids. Fulvifomin B exhibited moderate antimalarial and antitubercular activites.

Abstract
The wood-rot basidiomycete Ganoderma colossus has been chemically investigated. Comparative analyses of the natural fruiting body, artificially cultivated fruiting bodies, and mycelial cultures resulted in the isolation, in total, of 13 new highly modified lanostanes, ganocolossusins A-H (1-8) and ganodermalactones T-X (9-13), together with 23 known compounds (14-36). There were significant overlaps of the same compounds among the three different states of the fungal materials. Ganocolossusin D (4) displayed the most potent antimalarial activity against Plasmodium falciparum K1 (multi-drug-resistant strain) with an IC50 value of 2.4 μM, while it was noncytotoxic to Vero cells at 50 μg/mL.

Abstract
In a continuation of our research into antitubercular lanostane triterpenoids from submerged cultures of Ganoderma species, three strains, Ganoderma orbiforme BCC 22325, Ganoderma sp. BCC 60695, and Ganoderma australe BCC 22314, have been investigated. Fourteen new lanostane triterpenoids, together with 35 known compounds, were isolated. Antitubercular activities of these mycelium-associated Ganoderma lanostanoids against Mycobacterium tuberculosis H37Ra were evaluated. Taken together with the assay data of previously isolated compounds, structure-activity relationships of the antitubercular activity are proposed. Most importantly, 3β- and 15α-acetoxy groups were shown to be critical for antimycobacterial activity. The most potent compound was (24E)-3β,15α-diacetoxylanosta-7,9(11),24-trien-26-oic acid (35).

Nine alliacane sesquiterpenoids, inonoalliacanes A-I, were isolated from culture broth of the basidiomycete Inonotus sp. BCC 22670. The structures were elucidated on the basis of NMR spectroscopic and mass spectrometry data. The absolute configuration of inonoalliacane F was determined by application of the modified Mosher's method. Inonoalliacane A, the most abundant sesquiterpene constituent, exhibited moderate antibacterial activity against Bacillus cereus, whereas inonoalliacane B showed antiviral activity against herpes simplex virus type 1.

Abstract
Seven new lanostane-type triterpenes, hypocrellols A-G (1-7), and six new hopane-type triterpenes, 7β,15α-dihydroxy-22(29)-hopene (8), 3β,7β-dihydroxy-22(29)-hopene (9), 3β-acetoxy-15α-hydroxy-22(29)-hopene (10), 3β,7β,15α,22-tetrahydroxyhopane (11), 3β-acetoxy-7β,15α,22-trihydroxyhopane (12), and 7β,15α,22-trihydroxyhopane (13), were isolated from the scale insect pathogenic fungus Hypocrella sp. BCC 14524. The structures of the new compounds were elucidated by analyses of the NMR spectroscopic and mass spectrometry data. The structure of 1 was confirmed by X-ray crystallography.

Abstract
The insect pathogens in the genus Torrubiella s. lat. were recently divided into new genera based on molecular phylogenetic characters. Isolates collected at various locations in Thailand, were tested for their productivity of a hopane-type triterpene, zeorin (6α,22-dihydroxyhopane), when cultured in potato dextrose broth under static conditions. Among the 49 strains of Torrubiella s. lat. species, Conoideocrella luteorostrata (ten strains) and C. tenuis (seven strains), all collected on scale insects (Hemiptera), produced zeorin, whereas another six strains of Orbiocrella petchii (which was recently removed from Torrubiella) failed in the detection of this secondary metabolite. All other Torrubiella s. lat. (26 strains), collected on other insect hosts including leafhoppers (eight strains), Lepidoptera (one strain), and spiders (17 strains), produced no detectable zeorin. Paecilomyces cinnamomeus (nine strains), the anamorph of C. luteorostrata, also produced zeorin. These results correspond with the recent taxonomic reclassification based on multigene phylogeny.

Abstract
A novel cyclodepsipeptide, cordycommunin (1), and two dihydroisocoumarins (2 and 3) were isolated from the insect pathogenic fungus Ophiocordyceps communis BCC 16475. The absolute configurations of the amino acid residues of 1 were addressed by application of Marfey's method. Cordycommunin (1) showed growth inhibition of Mycobacterium tuberculosis H37Ra with an MIC value of 15 microM. This compound also exhibited weak cytotoxicity to KB cells with an IC50 of 45 microM, while it was inactive against BC, NCI-H187, and Vero cell lines at a concentration of 88 microM (50 microg/mL).

Abstract
The scale insect pathogens Hypocrella s. lat. and their Aschersonia anamorphs, collected at various locations in Thailand, were surveyed for their productivity of three hopane triterpenes, zeorin (6alpha,22-dihydroxyhopane), dustanin (15alpha,22-dihydroxyhopane), and 3beta-acetoxy-15alpha,22-dihydroxyhopane, when cultured in a liquid medium (potato-dextrose broth) under static conditions. Among 53 strains of Aschersonia species, 48 strains (91 %) produced at least one of these compounds. Hypocrella and Moelleriella species (43 strains) also frequently produced these triterpenoids; only two strains lacked all of these triterpenes. The results demonstrate that hopane triterpenes may be suitable for use as chemotaxonomic markers for Hypocrella and Moelleriella species and their Aschersonia anamorphs.
