Hirsutane Sesquiterpenes from Cultures of the Basidiomycete Marasmiellus sp. BCC 22389

Abstract Two new hirsutane sesquiterpenes, marasmiellins A (1) and B (2), were isolated from cultures of the basidiomycete Marasmiellus sp. BCC 22389. The structures were elucidated on the basis of NMR spectroscopic and mass spectrometry data. The absolute configuration of marasmiellin B was determined by application of the modified Mosher’s method. Graphical Abstrac

Drimane-Type Sesquiterpenoids Derived from the Tropical Basidiomycetes <i>Perenniporia centrali-africana</i> and <i>Cerrena</i> sp. nov

Five new drimane-type sesquiterpenoids were isolated from cultures of the tropical basidiomycetes, Perenniporia centrali-africana (originating from Kenya) and Cerrena sp. nov. (originating from Thailand). A new pereniporin A derivative (1), a new drimane-type sesquiterpene lactam (2), and the new 6,7-Dehydro-isodrimenediol (3) were isolated from P. centrali-africana. In parallel, the two new drimane-type sesquiterpene lactams 5 and 6 were isolated together with known isodrimenediol (4) from Cerrena sp. This is the first report of drimane-type sesquiterpene lactams from basidiomycetes. The structures were elucidated based on 1D and 2D nuclear magnetic resonance (NMR) spectroscopic data, in combination with high-resolution electrospray mass spectrometric (HR-ESIMS) data. The compounds were devoid of significant antimicrobial and cytotoxic activities

Antitubercular Lanostane Triterpenes from Cultures of the Basidiomycete <i>Ganoderma</i> sp. BCC 16642

Sixteen new lanostane triterpenoids (<b>1</b>–<b>16</b>), together with 26 known compounds (<b>17</b>–<b>42</b>), were isolated from cultures of the basidiomycete <i>Ganoderma</i> sp. BCC 16642. Antitubercular activities of these <i>Ganoderma</i> lanostanoids against <i>Mycobacterium tuberculosis</i> H37Ra were evaluated, and structure–activity relationships are proposed

Two new Russula species (fungi) from dry dipterocarp forest in Thailand suggest niche specialization to this habitat type

Dry dipterocarp forests are among the most common habitat types in Thailand. Russulaceae are known as common ectomycorrhizal symbionts of Dipterocarpaceae trees in this type of habitat. The present study aims to identify collections of Russula subsection Amoeninae Buyck from dry dipterocarp forests in Thailand. A multi-locus phylogenetic analysis placed Thai Amoeninae collections in two novel lineages, and they are described here as R. bellissima sp. nov. and R. luteonana sp. nov. The closest identified relatives of both species were sequestrate species suggesting that they may belong to drought-adapted lineages. An analysis of publicly available ITS sequences in R. subsect. Amoeninae did not confirm evidence of any of the new species occurring in other Asian regions, indicating that dry dipterocarp forests might harbor a novel community of ectomycorrhizal fungi. Macromorphological characters are variable and are not totally reliable for distinguishing the new species from other previously described Asian Amoeninae species. Both new species are defined by a combination of differentiated micromorphological characteristics in spore ornamentation, hymenial cystidia and hyphal terminations in the pileipellis. The new Amoeninae species may correspond to some Russula species collected for consumption in Thailand, and the detailed description of the new species can be used for better identification of edible species and food safety in the region

Antitubercular Activity of Mycelium-Associated <i>Ganoderma</i> Lanostanoids

In a continuation of our research into antitubercular lanostane triterpenoids from submerged cultures of <i>Ganoderma</i> species, three strains, <i>Ganoderma orbiforme</i> BCC 22325, <i>Ganoderma</i> sp. BCC 60695, and <i>Ganoderma australe</i> BCC 22314, have been investigated. Fourteen new lanostane triterpenoids, together with 35 known compounds, were isolated. Antitubercular activities of these mycelium-associated <i>Ganoderma</i> lanostanoids against <i>Mycobacterium tuberculosis</i> 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 (24<i>E</i>)-3β,15α-diacetoxylanosta-7,9­(11),24-trien-26-oic acid (<b>35</b>)
