Abstract
Three new phthalide derivatives (1‒3) together with two known compounds, erinaceolactone B (4) and hericerin III (5), were isolated from the culture broth of Dentipellis fragilis. The chemical structures of 1‒5 were determined by analyses of their 1D-, 2D-NMR, and MS. The absolute configuration of 1 was determined by CD analysis. The isolated compounds were assessed for their cytotoxic activities against A549, DU145, HCT116, and HT1080 cancer cell lines. Compounds 1‒5 showed strong cytotoxic activities against DU145, with IC50 values ranging from 14.3 to 16.1 µM. Additionally, all compounds showed moderate or weak cytotoxic activities against all cell lines except for compounds 4 and 1 which showed no cytotoxic activities against A549 and HCT116 cancer cell lines, respectively. Against HT1080 cancer cell line, only compound 2 displayed moderate cytotoxic activity.

Abstract
Glycosylation is a prevalent post-modification found in natural products and has a significant impact on the structural diversity and activity variation of natural products. Glucosylation is the most common type of glycosylation, whereas xylosylation is relatively rare. Despite their unique chemical structures and beneficial activities, xylosylated natural products from microorganisms have received little attention. This review provides, for the first time, a comprehensive summary of 126 microbial-derived xylosylated natural products, including xylosyl-cyathane diterpenes, xylosylated triterpenes, xylosyl aromatic compounds, and others. Among these compounds, xylosyl-cyathane diterpenes represent the highest number of derivatives, followed by xylosylated triterpenes. Xylosyl compounds from bacterial sources have less defined structural profiles compared to those from fungi. The characterization of xylosyltransferase EriJ from Basidiomycota extended the structural diversity of xylosyl cyathane diterpenes. This work provides a valuable reference for the research and use of xylosyltransferase for drug discovery and synthetic chemistry. Further work is needed to explore the potential applications of microbial derived xylosyl compounds and to develop novel xylosyl transferases. With the deepening of genomic sequencing of medicinal fungi, more biosynthesis of bioactive xylosyl compounds is expected to be elucidated in the future.

Abstract
Seven undescribed compounds, dentipellinones A‒D (1, 2, 5, and 6), dentipellinol (3), methoxyerinaceolactone B (4), and erinaceolactomer A (7), were isolated from the culture broth of Dentipellis fragilis. Chemical structures of these isolated compounds were determined by analyses of 1D and 2D-NMR and MS data in comparison with data reported in the literature. Absolute configurations of 1‒7 were also determined by Electronic Circular Dichroism calculations. The isolated compounds were evaluated for their anti-inflammatory effects on NO production and pro-inflammatory cytokines levels in LPS-stimulated RAW264.7 cells. Compounds 5 and 7 were evaluated for their anti-inflammatory effects on NO production and pro-inflammatory cytokine levels in LPS-stimulated RAW264.7 cells. They exhibited inhibitory effects on LPS-induced NO production in a dose-dependent manner, and significantly reduced the levels of inflammatory-related cytokines such as IL-1β and IL-6. TNF-α was not involved in the anti-inflammatory effects of these compounds. Finally, compounds 5 and 7 showed significant anti-inflammatory effects.

Abstract
During the search for natural antibiotics from fungal metabolites, a new cyathane diterpenoid, fragilicine A (1), and three known cyathane diterpenoids, erinacines I, A, and B (2-4) were isolated from the culture broth of Dentipellis fragilis. Chemical structures of 1-4 were determined by analyses of 1D- and 2D-NMR and MS data and by comparisons with data of those reported in the literature. These isolated compounds were assessed for their antimicrobial activities against Bacillus subtilis, B. atrophaeus, B. cereus, Listeria monocytogenes, Fusarium oxysporum, Diaporthe sp., and Rhizoctonia solani. These compounds showed weak antimicrobial activities.

Antibiotics (Basel) 2022; 11:antibiotics11081072. [PMID: 36009941 PMCID: PMC9405216 DOI: 10.3390/antibiotics11081072] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 08/04/2022] [Accepted: 08/06/2022] [Indexed: 11/16/2022] Open
Abstract
In our continued search for biologically active metabolites from cultures of rare Basidiomycota species, we found eight previously undescribed cyathane-xylosides from submerged cultures of Dentipellis fragilis, which were named dentifragilins A–H. In addition, the known cyathane derivatives striatal D and laxitextine A were isolated. All compounds were characterized by high-resolution electrospray ionization mass spectrometry (HR-ESIMS) as well as by 1D and 2D nuclear magnetic resonance (NMR) spectroscopy. Several of the compounds exhibited significant activities in standardized cell-based assays for the determination of antimicrobial and cytotoxic effects. The discovery of cyathanes in the genus Dentipellis has chemotaxonomic implications, as this class of diterpenoids has already been shown to be characteristic for mycelial cultures of the related genera Hericium and Laxitextum, which are classified as Dentipellis in the family Hericiaceae.
