[PMID: 37888437 PMCID: PMC10608504 DOI: 10.3390/md21100502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 09/16/2023] [Accepted: 09/18/2023] [Indexed: 10/28/2023] Open
Abstract
The prevalence of gout and the adverse effects of current synthetic anti-gout drugs call for new natural and effective xanthine oxidase (XOD) inhibitors to target this disease. Based on our previous finding that an edible seaweed Pterocladiella capillacea extract inhibits XOD, XOD-inhibitory and anti-inflammatory activities were used to evaluate the anti-gout potential of different P. capillacea extract fractions. Through affinity ultrafiltration coupled with liquid chromatography tandem mass spectrometry (LC-MS/MS), feature-based molecular networking (FBMN), and database mining of multiple natural products, the extract's bioactive components were traced and annotated. Through molecular docking and ADMET analysis, the possibility and drug-likeness of the annotated XOD inhibitors were predicted. The results showed that fractions F4, F6, F4-2, and F4-3 exhibited strong XOD inhibition activity, among which F4-3 reached an inhibition ratio of 77.96% ± 4.91% to XOD at a concentration of 0.14 mg/mL. In addition, the P. capillacea extract and fractions also displayed anti-inflammatory activity. Affinity ultrafiltration LC-MS/MS analysis and molecular networking showed that out of the 20 annotated compounds, 8 compounds have been previously directly or indirectly reported from seaweeds, and 4 compounds have been reported to exhibit anti-gout activity. Molecular docking and ADMET showed that six seaweed-derived compounds can dock with the XOD activity pocket and follow the Lipinski drug-like rule. These results support the value of further investigating P. capillacea as part of the development of anti-gout drugs or related functional foods.

Abstract
Fungi are ubiquitous in distribution and are found in grasses to hot springs. Their mode of nutrition provides sustenance for living and propagation. Ironically, varied fungal species have developed customized strategies for protection and survival by producing diverse secondary metabolites. The review aimed to project the contrasting potential features of the endophytic and thermophilic fungi groups. The metabolites and the enzymes of endophytic and thermophilic fungi served as the backbone to thrive and adapt within-host and in extreme conditions like higher pH, heat, and salinity, respectively. Identification, knowledge of their biochemistry and pathway, exploration, production, and utilization of these bioactive molecules in various commercial, industrial, and pharmaceutical domains were briefly discussed. The uniqueness of endophytes includes stress management and improved biomass production of the host, green fuel production, omnipresence, selected triple-symbiosis with the virus, synthesis of polyketides, and other active metabolites are widely used in biomedical applications and agriculture management. This review attempted to limelight the specific applications of thermophilic fungal metabolites and the roles of thermo-stable enzymes in bioprospecting. Moreover, probing the metabolites of thermophiles rendered novel antibiotic compounds, which were proven effective against multi-drug resistant bacteria and harboured the potential to curtail infectious diseases.

Abstract
Eighteen linear triquinane sesquiterpenoids (LTSs), including seventeen previously undescribed ones (hirsutuminoids A-Q), were isolated from the fermentation of the fungus Stereum hirsutum (Willd.) Pers. The structures and absolute configurations of the isolates were characterized by extensive spectroscopic analysis (1D, 2D NMR, and HRMS data), together with comparing the experimental and calculated data of both electronic circular dichroism and NMR data, as well as X-ray crystallography. Based on the literature survey and efforts on constructing the absolute configurations of these LTSs in this study, one empirical rule about the orientations of substitutions at C-2/C-3/C-7/C-9 was summarized. Anti-inflammatory and cytotoxic bioassays showed that only hirsutuminoid B inhibited the nitric oxide (NO) production in RAW 264.7 macrophages with an IC50 value, 18.9 μM.

Abstract
Endophytic fungi are a highly diverse group of fungi that intermittently colonize all plants without causing symptoms of the disease. They sense and respond to physiological and environmental changes of their host plant and microbiome. The inter-organism interactions are largely driven by chemical networks mediated by specialized metabolites. The balance of these complex interactions leads to healthy and strong host plants. Endophytic strains have particular machinery to produce a plethora of secondary metabolites with a variety of bioactivities and unknown functions in an ecological niche. Terpenoids play a key role in endophytism and represent an important source of bioactive molecules for human health and agriculture. In this review, we describe the role of endophytic fungi in plant health, fungal terpenoids in multiple interactions, and bioactive fungal terpenoids recently reported from endophytes, mainly from plants used in traditional medicine, as well as from algae and mangroves. Additionally, we highlight endophytic fungi as producers of important chemotherapeutic terpenoids, initially discovered in plants. Despite advances in understanding endophytism, we still have much to learn in this field. The study of the role, the evolution of interactions of endophytic fungi and their terpenoids provide an opportunity for better applications in human health and agriculture.

Abstract
Fungi associated with macroalgae are less known when compared with those on wood in the marine environment. In this study, we assessed the diversity of fungi associated with the red alga Pterocladiella capillacea at Chao-Jin Park, Keelung, Taiwan. Algal segments of healthy and dead thalli were washed/sterilized with different solutions (sterile artificial seawater, 70% ethanol, and 4% sodium hypochlorite), plated on three different media (glucose-yeast extract-peptone seawater agar (GYPS), potato dextrose seawater agar (PDAS), and artificial seawater agar (SA)), and isolated as pure cultures. Identification was mainly based on BLAST search analysis of the internal transcribed spacers of rDNA (ITS). The highest isolation frequency (no. of segment with fungi/total no. of segment × 100) was in dead thalli (61.23%), thalli washed with seawater (88.38%), and thalli plated on GYPS (62.10%). A total of 3187 isolates were cultured, representing 129 taxa (in 67 genera); the higher species richness was isolated from healthy thalli (119 species), thalli washed with seawater (111 species), and on GYPS (112 species). Ascomycota (Eurotiales, Hypocreales, Capnodiales, Pleosporales, Xylariales) dominated the fungal community in P. capillacea with many basidiomycetous yeasts and few Mucoromycota. Aspergillus, Cladosporium, Penicillium (Ascomycota), and Rhodosporidium (Basidiomycota) were the dominant genera associated with the alga. The surface washing/sterilization schemes of algal thalli affected fungal diversity, but the isolation media used did not. While these genera are known producers of antimicrobial secondary metabolites, they might form a mutualistic relationship with P. capillacea by exchanging nutrients from photosynthesis for protection from microbial diseases.

Abstract
Theissenia cinerea 89091602 is a previously reported plant-derived bioactive fungal strain, and the active principles separated from the extracts of its submerged culture were shown to exhibit potent anti-neuroinflammatory activities in both cellular study and animal testing. In a continuation of our previous investigation on the bioactive entities from this fungus, solid state fermentation was performed in an attempt to diversify the bioactive secondary metabolites. In the present study, five previously unreported polyketides, theissenophenol (1), theissenepoxide (2), theissenolactone D (3), theissenone (4), and theissenisochromanone (5), together with the known theissenolactone B (6), theissenolactone C (7), and arthrinone (8), were isolated and characterized through spectroscopic analysis and comparison with the literature data. The configurations of theissenepoxide (2) and theissenisochromanone (5) were further corroborated by single-crystal X-ray diffraction data analysis. Theissenone (4), theissenolactone B (6), theissenolactone C (7), and arthrinone (8) exhibited potent nitric oxide production inhibitory activities in murine brain microglial BV-2 cells with IC50 values of 5.0 ± 1.0, 4.5 ± 0.6, 1.1 ± 0.1, and 3.2 ± 0.3 μM, respectively, without any significant cytotoxic effects.

Abstract
Owing to high strain energy, molecules with trans-fused bicyclo[3.3.0]octane ring systems are very difficult to synthesize, and there are very few approaches to access them. Recently, a number of natural products with such ring systems have been made by the synthetic community. However, there has been no review in this field before. This review provides a systematic and comprehensive discussion on the synthesis of natural products containing trans-fused bicyclo[3.3.0]octanes and the historical context of this work. The prospects for future research in this field are also discussed. Covering the literature before 2021, this review aims to offer a helpful reference for total synthesis of highly strained natural products containing trans-fused bicyclo[3.3.0]octane ring systems.

Abstract
Plant endophytic fungi are an important part of plant microecosystems and a natural resource for human survival and development. Various bioactive natural products produced by plant endophytic fungi show promising prospects in biopharmacy, agricultural production, and industrial fermentation. Terpenoids, the most numerous and structurally diverse natural products from endophytic fungi, possess a broad range of biological activities and huge potential for drug development. It is critically significant for ecological and economic benefits to develop their activities. This paper utilized literature analysis to summarize 200 terpenoids with biological activities that are derived from plant endophytic fungi in China between 2017 and 2019. Among them, sesquiterpenoids were the most important kind of terpenoids, and Trichoderma and Aspergillus species were main terpenoid-producing plant endophytic fungi. Furthermore, these terpenoids displayed multifarious biological activities, including antimicrobial, antipathogenic, and anti-inflammatory activities, as well as cytotoxicity, antitumor agents, and enzyme inhibition.

Abstract
Marine-derived fungi are a significant source of pharmacologically active metabolites with interesting structural properties, especially terpenoids with biological and chemical diversity. In the past five years, there has been a tremendous increase in the rate of new terpenoids from marine-derived fungi being discovered. In this updated review, we examine the chemical structures and bioactive properties of new terpenes from marine-derived fungi, and the biodiversity of these fungi from 2015 to 2019. A total of 140 research papers describing 471 new terpenoids of six groups (monoterpenes, sesquiterpenes, diterpenes, sesterterpenes, triterpenes, and meroterpenes) from 133 marine fungal strains belonging to 34 genera were included. Among them, sesquiterpenes, meroterpenes, and diterpenes comprise the largest proportions of terpenes, and the fungi genera of Penicillium, Aspergillus, and Trichoderma are the dominant producers of terpenoids. The majority of the marine-derived fungi are isolated from live marine matter: marine animals and aquatic plants (including mangrove plants and algae). Moreover, many terpenoids display various bioactivities, including cytotoxicity, antibacterial activity, lethal toxicity, anti-inflammatory activity, enzyme inhibitor activity, etc. In our opinion, the chemical diversity and biological activities of these novel terpenoids will provide medical and chemical researchers with a plenty variety of promising lead compounds for the development of marine drugs.

Zhou HS, Cao SM, Liao HS, Huo HY. Hirsutanol A exhibits neuroprotective activities against sevoflurane-induced neurotoxicity in aged rats. Anat Rec (Hoboken) 2020; 304:591-601. [PMID: 32536020 DOI: 10.1002/ar.24473] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 03/26/2020] [Accepted: 04/03/2020] [Indexed: 01/07/2023]
Abstract
The neurotoxicity of the inhaled anesthetic, sevoflurane, has been documented in a number of studies. In this study, we conducted experiments to investigate whether Hirsutanol A (HA), a sesquiterpene compound from the fungus, Chondrostereum sp., can provide protection from sevoflurane-induced neurological toxicity in aged rats, and analyzed the underlying mechanisms. The cognitive dysfunction of rats following sevoflurane exposure was evaluated by behavioral tests. The neuronal cell survival was determined by Nissl staining. In addition, human neuroblastoma H4 cells were exposed to sevoflurane to establish an in vitro model. Apoptotic marker expression in hippocampal tissue was determined by western blotting. Cell apoptosis in vitro was also examined by TUNEL assay and flow cytometry. The expression and translocation of Nrf2 were examined by both western blot and immunofluorescence staining. Our results show that HA significantly attenuated sevoflurane-induced cognitive impairment in aged rats. In addition, HA treatment decreased sevoflurane-induced neuronal apoptosis in the hippocampus and alleviated Aβ accumulation. Our results also show that the neuroprotective effect of HA is associated with the activation of Nrf2 signaling. Human neuroblastoma H4 cells were used as a model to examine the protective activity of HA against sevoflurane-induced neurotoxicity. In addition, our results show that the inhibition of Nrf2 by a specific inhibitor or targeting siRNA significantly compromises the attenuating effect of HA on sevoflurane-induced cell apoptosis and Aβ accumulation. Our results suggest that HA may function as a neuroprotective agent against sevoflurane-induced neurotoxicity.

Lautié E, Russo O, Ducrot P, Boutin JA. Unraveling Plant Natural Chemical Diversity for Drug Discovery Purposes. Front Pharmacol 2020; 11:397. [PMID: 32317969 PMCID: PMC7154113 DOI: 10.3389/fphar.2020.00397] [Citation(s) in RCA: 78] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 03/16/2020] [Indexed: 12/11/2022] Open
Abstract
The screening and testing of extracts against a variety of pharmacological targets in order to benefit from the immense natural chemical diversity is a concern in many laboratories worldwide. And several successes have been recorded in finding new actives in natural products, some of which have become new drugs or new sources of inspiration for drugs. But in view of the vast amount of research on the subject, it is surprising that not more drug candidates were found. In our view, it is fundamental to reflect upon the approaches of such drug discovery programs and the technical processes that are used, along with their inherent difficulties and biases. Based on an extensive survey of recent publications, we discuss the origin and the variety of natural chemical diversity as well as the strategies to having the potential to embrace this diversity. It seemed to us that some of the difficulties of the area could be related with the technical approaches that are used, so the present review begins with synthetizing some of the more used discovery strategies, exemplifying some key points, in order to address some of their limitations. It appears that one of the challenges of natural product-based drug discovery programs should be an easier access to renewable sources of plant-derived products. Maximizing the use of the data together with the exploration of chemical diversity while working on reasonable supply of natural product-based entities could be a way to answer this challenge. We suggested alternative ways to access and explore part of this chemical diversity with in vitro cultures. We also reinforced how important it was organizing and making available this worldwide knowledge in an "inventory" of natural products and their sources. And finally, we focused on strategies based on synthetic biology and syntheses that allow reaching industrial scale supply. Approaches based on the opportunities lying in untapped natural plant chemical diversity are also considered.

Abstract
Inflammation is a generalized, nonspecific, and beneficial host response of foreign challenge or tissue injury. However, prolonged inflammation is undesirable. It will cause loss function of involve organs, such as heat, pain redness, and swelling. Marine natural products have gained more and more attention due to their unique mechanism of anti-inflammatory action, and have considered a hotspot for anti-inflammatory drug development. Marine-derived fungi are promising sources of structurally unprecedented bioactive natural products. So far, a plethora of new secondary metabolites with anti-inflammatory activities from marine-derived fungi had been widely reported. This review covers 133 fungal metabolites described in the period of 2000 to 2018, including the structures and origins of these secondary metabolites.

Hirsutanol A Attenuates Lipopolysaccharide-Mediated Matrix Metalloproteinase 9 Expression and Cytokines Production and Improves Endotoxemia-Induced Acute Sickness Behavior and Acute Lung Injury. Mar Drugs 2019; 17:md17060360. [PMID: 31213027 PMCID: PMC6627105 DOI: 10.3390/md17060360] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Revised: 06/11/2019] [Accepted: 06/14/2019] [Indexed: 12/15/2022] Open
Abstract
Activated human monocytes/macrophages, which increase the levels of matrix metalloproteinases (MMPs) and pro-inflammatory cytokines, are the essential mechanisms for the progression of sepsis. In the present study, we determined the functions and mechanisms of hirsutanolA (HA), which is isolated from the red alga-derived marine fungus Chondrostereum sp. NTOU4196, on the production of pro-inflammatory mediators produced from lipopolysaccharide (LPS)-treated THP-1 cells. Our results showed that HA suppressed LPS-triggered MMP-9-mediated gelatinolysis and expression of protein and mRNA in a concentration-dependent manner without effects on TIMP-1 activity. Also, HA significantly attenuated the levels of TNF-α, IL-6, and IL-1β from LPS-treated THP-1 cells. Moreover, HA significantly inhibited LPS-mediated STAT3 (Tyr705) phosphorylation, IκBα degradation and ERK1/2 activation in THP-1 cells. In an LPS-induced endotoxemia mouse model, studies indicated that HA pretreatment improved endotoxemia-induced acute sickness behavior, including acute motor deficits and anxiety-like behavior. HA also attenuated LPS-induced phospho-STAT3 and pro-MMP-9 activity in the hippocampus. Notably, HA reduced pathologic lung injury features, including interstitial tissue edema, infiltration of inflammatory cells and alveolar collapse. Likewise, HA suppressed the induction of phospho-STAT3 and pro-MMP-9 in lung tissues. In conclusion, our results provide pharmacological evidence that HA could be a useful agent for treating inflammatory diseases, including sepsis.

Abstract
Linear triquinane sesquiterpenoids represent an important class of natural products. Most of these compounds were isolated from fungi, sponges, and soft corals, and many of them displayed a wide range of biological activities. On account of their structural diversity and complexity, linear triquinane sesquiterpenoids present new challenges for chemical structure identification and total synthesis. 118 linear triquinane sesquiterpenoids were classified into 8 types, named types I–VIII, based on the carbon skeleton and the position of carbon substituents. Their isolation, structure elucidations, biological activities, and chemical synthesis were reviewed. This paper cited 102 articles from 1947 to 2018.

Abstract
One new cerapicane cerrenin A (1), and two new isohirsutane sesquiterpenoids cerrenins B and C (2 and 3), were isolated from the broth extract of Cerrena sp. A593. Cerrenin A featured a rare cage-like bicyclo[3.2.1]octane skeleton, and cerrenin B represented the rearranged triquinane-type sesquiterpenoid. Their structures were extensively elucidated by NMR spectroscopic analysis with the absolute configuration determined by X-ray crystallography and ECD calculations. The anti-cancer activity for all the compounds were evaluated, and their plausible biosynthetic relationships involving fascinating carbon skeleton rearrangements were also suggested.
