“…HSQC and HMBC data suggested that in case of compound 1 a 22-hydroxy-24-en side chain was present. 1D and 2D ROESY data were in accordance with the suggested structure and proved that the relative configurations of C-4, C-5, C-10, C-13, C-14, C-17, and C-20 were identical in compound 1 and gilvsin D as well as in natalic acid (7). In addition to this, based on the findings of Barrera and coworkers [17] the ca.…”

“…The 1 H and 13 C NMR spectra of compound 1 presented similar spectral features to those reported for gilvsin D [15] and obtained for natalic acid (7) [16]. Consecutive analysis of the COSY, HSQC and HMBC spectra of 1 showed that it is a structural analogue of gilvsin D and natalic acid (7), and enabled the complete 1 H and 13 C NMR assignments listed in Table 1. Based on the spectral data similarities, all three compounds share the same degraded lanosterol skeleton.…”

“…Among these, Fuscoporia Murrill is one of the largest genus, distributed on all forested continents [6]. Based on recent taxonomic studies, 50 species are accepted in the genus, which are divided into six phylogenetic lineages [7,8]. The so called "F. torulosa group" comprises ten species, of which only two have been reported from Europe: F. wahlbergii (Fr.)…”

Investigation of the methanol extract of the poroid fungus Fuscoporia torulosa resulted in the isolation of a novel triterpene, fuscoporic acid (1) together with inoscavin A and its previously undescribed Z isomer (2 and 3), 3,4-dihydroxy-benzaldehide (4), osmundacetone (5), senexdiolic acid (6), natalic acid (7), and ergosta-7,22-diene-3-one (8). The structures of fungal compounds were determined on the basis of NMR and MS spectroscopic analysis, as well as molecular modelling studies. Compounds 1, 6-8 were examined for their antibacterial properties on resistant clinical isolates, and cytotoxic activity on human colon adenocarcinoma cell lines. Compound 8 was effective against Colo 205 (IC50 11.65±1.67 µM), Colo 320 (IC50 8.43±1.1 µM) and MRC-5 (IC50 7.92±1.42 µM) cell lines. Potentially synergistic relationship was investigated between 8 and doxorubicin, which revealed a synergism between the examined compounds with a combination index (CI) at the 50% growth inhibition dose (ED50) of 0.521±0.15. Several compounds (1, and 6-8) were tested for P‐glycoprotein modulatory effect in Colo 320 resistant cancer cells, but none of the compounds proved to be effective in this assay. Fungal metabolites 2-5 were evaluated for their antioxidant activity using the oxygen radical absorbance capacity (ORAC) and DPPH assays. Compounds 4 and 5 proved to possess considerable antioxidant effect with EC50 0.25±0.01 (DPPH) and 12.20±0.92 mmol TE/g (ORAC). The current article provides valuable information on both chemical and pharmacological profiles of Fuscoporia torulosa, paving the way for future studies with this species.

“…Three new species of Junghuhnia are described from Southern China in the present paper. Although extensive surveys on wood-decaying fungi in Southern China were carried out, and more than 3000 specimens were collected with 132 new polypore (Dai 2010;Zhao et al 2015;Chen et al 2020;Wu et al 2020), it is expected that more new taxa will be found after additional investigations based on careful morphological examinations and phylogenetic analyses because of the rich woody plant species in subtropical and tropical China.…”

In this study, taxonomic and phylogenetic analyses of Junghuhnia were performed. Three new species were characterised according to morphological characteristics and molecular phylogenetic analysis using ITS and nLSU sequences. They are J. austrosinensissp. nov., J. nandinaesp. nov. and J. subcollabenssp. nov.Junghuhnia austrosinensis is characterised by resupinate, thin basidiomata with white to buff-yellow hymenophore, small pores (9–11 per mm), clamped generative hyphae possessing hymenial cystidia, ellipsoid basidiospores (2.5–3 × 1.7–2 µm) and growth on fallen bamboo or angiosperm branch. Junghuhnia nandinae is characterised by resupinate basidiomata with pink to salmon pores and a distinct white margin, clamp generative hyphae, interwoven tramal hyphae, ellipsoid basidiospores measuring 2.6–3.2 × 1.8–2 µm and growth on Nandina domestica. Junghuhnia subcollabens is characterised by resupinate basidiomata with pale salmon to brownish vinaceous hymenophore, small pores (10–12 per mm), generative hyphae with simple septa and clamp connections, interwoven tramal hyphae, lunate basidiospores measuring 2.9–3.4 × 1.6–1.8 µm and thriving on rotten wood of angiosperms.
