Abstract
Nigrospora (Xylariales, Apiosporaceae) consists of species of terrestrial plant endophytes and pathogens. Nigrospora has also been reported in marine environments such as mangroves, sea fans, and macroalgae. However, limited research has been conducted on Nigrospora associated with macroalgae. Here, we isolated Nigrospora species from three types of algae (brown, green, and red algae) from Korean islands (Chuja, Jeju, and Ulleung) based on phylogenetic analyses of multigenetic markers: the internal transcribed spacers (ITS), beta-tubulin (BenA), and translation elongation factor 1 (TEF1-α). A total of 17 Nigrospora strains were isolated from macroalgae and identified as nine distinct species. The majority of Nigrospora species (seven) were found on brown algae, followed by red algae (three), and then green algae (two). To our understanding, this study represents the first account of N. cooperae, N. covidalis, N. guilinensis, N. lacticolonia, N. osmanthi, N. pyriformis, and N. rubi occurring in marine environments. Additionally, this study provides the first report of the occurrence of N. cooperae, N. covidalis, N. guilinensis, N. lacticolonia, and N. osmanthi in South Korea. This study will provide valuable insights for future research exploring the functions of fungi in macroalgal communities.

Fitoterapia 2022; 161:105254. [PMID: 35872163 DOI: 10.1016/j.fitote.2022.105254] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/11/2022] [Accepted: 07/17/2022] [Indexed: 11/16/2022]
Abstract
Secondary metabolites produced by the ascomycetes have attracted wide attention from researchers. Their diverse chemical structures and rich biological activities are essential in medicine, food, and agriculture. The monophyletic Nigrospora genus belongs to the Apiosporaceae family and is a rich source of novel and diverse bioactive metabolites. It occurs as a common plant pathogen, endophyte, and saprobe distributed in many ecosystems worldwide. Researchers have focused on discovering new species and secondary metabolites in the past ten years. The host diseases caused by Nigrospora species are also investigated. This review describes 50 references from Web of Science, CNKI, Google Scholar and PubMed related to the secondary metabolites from Nigrospora. Here, a total of 231 compounds isolated from five known species and 21 unidentified species of Nigrospora from January 1991 to June 2022 are summarized. Their structures are attributed to polyketides, terpenoids, steroids, N-containing compounds, and fatty acids. Meanwhile, 77 metabolites exhibited various biological activities like cytotoxic, antifungal, antibacterial, antiviral, antioxidant, anti-inflammatory, antileukemic, antimalarial, phytotoxic, enzyme inhibitory, etc. Notably, this review presents a comprehensive literature survey focusing on the chemistry and bioactivity of secondary metabolites from Nigrospora.

Hydroanthraquinones from Nigrospora sphaerica and Their Anti-inflammatory Activity Uncovered by Transcriptome Analysis. JOURNAL OF NATURAL PRODUCTS 2022; 85:1474-1485. [PMID: 35696541 DOI: 10.1021/acs.jnatprod.1c01141] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/15/2023]
Abstract
Transcriptome analysis is shown to be an effective strategy to understand the potential function of natural products. Here, it is reported that 11 previously undescribed hydroanthraquinones [nigroquinones A-K (1-11)], along with eight known congeners, were isolated from Nigrospora sphaerica. Their structures were elucidated by interpreting spectroscopic and spectrometric data including high-resolution mass spectra and nuclear magnetic resonance. The absolute configurations of 1-11 were confirmed by electronic circular dichroism calculations. Transcriptome analysis revealed that 3 (isolated in the largest amount) might be anti-inflammatory. Assays based on LPS-induced RAW264.7 macrophages and zebrafish embryos confirmed that some of the isolated hydroanthraquinones attenuated the secretion of pro-inflammatory mediators in vitro and in vivo. Further Western blotting and immunofluorescence experiments indicated that 4 (which showed the most obvious nitric oxide inhibition) could suppress the expression of nuclear factor-kappa-B (NF-κB), phosphorylation of the inhibitor of NF-κB kinase and inhibit the transportation of NF-κB to the nucleus. Hence, the suppression of the NF-κB signaling pathway may be responsible for the anti-inflammatory effect. These results show that bioactivity evaluation on the basis of transcriptome analysis may be effective in the functional exploration of natural products.

Abstract
Covering 1989 to 2020The mangrove forests are a complex ecosystem occurring at tropical and subtropical intertidal estuarine zones and nourish a diverse group of microorganisms including fungi, actinomycetes, bacteria, cyanobacteria, algae, and protozoa. Among the mangrove microbial community, mangrove associated fungi, as the second-largest ecological group of the marine fungi, not only play an essential role in creating and maintaining this biosphere but also represent a rich source of structurally unique and diverse bioactive secondary metabolites, attracting significant attention of organic chemists and pharmacologists. This review summarizes the discovery relating to the source and characteristics of metabolic products isolated from mangrove-associated fungi over the past thirty years (1989-2020). Its emphasis included 1387 new metabolites from 451 papers, focusing on bioactivity and the unique chemical diversity of these natural products.
