Nielsen MR, Sørensen T, Pedersen TB, Westphal KR, Díaz Fernández De Quincoces L, Sondergaard TE, Wimmer R, Brown DW, Sørensen JL. Final piece to the Fusarium pigmentation puzzle - Unraveling of the phenalenone biosynthetic pathway responsible for perithecial pigmentation in the Fusarium solani species complex. Fungal Genet Biol 2024; 174:103912. [PMID: 39004163 DOI: 10.1016/j.fgb.2024.103912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/29/2024] [Accepted: 07/04/2024] [Indexed: 07/16/2024]
Abstract
The Fusarium solani species complex (FSSC) is comprised of important pathogens of plants and humans. A distinctive feature of FSSC species is perithecial pigmentation. While the dark perithecial pigments of other Fusarium species are derived from fusarubins synthesized by polyketide synthase 3 (PKS3), the perithecial pigments of FSSC are derived from an unknown metabolite synthesized by PKS35. Here, we confirm in FSSC species Fusarium vanettenii that PKS35 (fsnI) is required for perithecial pigment synthesis by deletion analysis and that fsnI is closely related to phnA from Penicillium herquei, as well as duxI from Talaromyces stipentatus, which produce prephenalenone as an early intermediate in herqueinone and duclauxin synthesis respectively. The production of prephenalenone by expression of fsnI in Saccharomyces cerevisiae indicates that it is also an early intermediate in perithecial pigment synthesis. We next identified a conserved cluster of 10 genes flanking fsnI in F. vanettenii that when expressed in F. graminearum led to the production of a novel corymbiferan lactone F as a likely end product of the phenalenone biosynthetic pathway in FSSC.

Abstract
Among microorganisms, fungi are the ones that have the most imagination in producing secondary metabolites with the most varied structural differences, which are produced through different biosynthetic pathways. Therefore, they synthesize secondary metabolites classifiable into numerous families of natural compounds such as amino acids, alkaloids, anthraquinones, aromatic compounds, cyclohexene epoxides, furanones, macrolides, naphthoquinones, polyketides, pyrones, terpenes, etc. They also produced metabolites with very complex structures that can not be classified in the known families of natural compounds. Many fungal metabolites show different biological activities with potential applications in agriculture, food chemistry, cosmetics, pharmacology and medicine. This review is focused on the fungal secondary metabolites with anticancer activity isolated in the last ten years. For some metabolites, when described, their biosynthetic origin, the mode of action and the results of structure activity relationships studies are also reported.

Abstract
Mushrooms are known not only for their taste but also for beneficial effects on health attributed to plethora of constituents. All mushrooms belong to the kingdom of fungi, which also includes yeasts and molds. Each year, hundreds of new metabolites of the main fungal sterol, ergosterol, are isolated from fungal sources. As a rule, further testing is carried out for their biological effects, and many of the isolated compounds exhibit one or another activity. This study aims to review recent literature (mainly over the past 10 years, selected older works are discussed for consistency purposes) on the structures and bioactivities of fungal metabolites of ergosterol. The review is not exhaustive in its coverage of structures found in fungi. Rather, it focuses solely on discussing compounds that have shown some biological activity with potential pharmacological utility.

Abstract
The fungus Eurotium sp., derived from the marine sponge Ircinia variabilis, was found to produce a diketopiperazine-indole alkaloid that we named fintiamin (1). Structural elucidation of 1 was achieved by extensive spectroscopic analysis including nuclear magnetic resonance spectroscopy and mass spectrometry. Compound 1 is a lipophilic terpenoid-dipeptide hybrid molecule that shows affinity for the cannabinoid CB1 receptor at low micromolar concentrations. Docking studies based on previous X-ray structures provide a plausible binding pose for compound 1 in the orthosteric binding site of the CB1 receptor.

Abstract
Among microorganisms, endophytic fungi are the least studied, but they have attracted attention due to their high biological diversity and ability to produce novel and bioactive secondary metabolites to protect their host plant against biotic and abiotic stress. These compounds belong to different structural classes, such as alkaloids, peptides, terpenoids, polyketides, and steroids, which could present significant biological activities that are useful for pharmacological or medical applications. Recent reviews on endophytic fungi have mainly focused on the production of novel bioactive compounds. Here, we focus on compounds produced by endophytic fungi, reported with uncommon bioactive structures, establishing the neighbor net and diversity of endophytic fungi. The review includes compounds published from January 2015 to December 2020 that were catalogued as unprecedented, rare, uncommon, or possessing novel structural skeletons from more than 39 different genera, with Aspergillus and Penicillium being the most mentioned. They were reported as displaying cytotoxic, antitumor, antimicrobial, antiviral, or anti-inflammatory activity. The solid culture, using rice as a carbon source, was the most common medium utilized in the fermentation process when this type of compound was isolated.

Abstract
Eight phenalenone derivatives, including four new compounds, aceneoherqueinones A and B (1 and 2), (+)-aceatrovenetinone A (3a), and (+)-aceatrovenetinone B (3d), along with four known congeners, (-)-aceatrovenetinone A (3b), (-)-aceatrovenetinone B (3c), (-)-scleroderolide (4a), and (+)-scleroderolide (4b), were characterized from the marine mangrove-derived fungus Penicillium herquei MA-370. Among them, compounds 1 and 2 are rare phenalenone derivatives featuring cyclic ether unit between C-5 and C-2'. All of these compounds were subjected to chiral HPLC analysis, and the unstable stereoisomers 3a-3d, containing configurationally labile chirality centers, were characterized by online HPLC-ECD measurements supported with TDDFT-ECD calculations. The structures of these compounds were elucidated by detailed analysis of their NMR and mass spectroscopic data, and the absolute configuration of compound 1 was confirmed by X-ray diffraction analysis, while those of compounds 2 and 3a-3d were determined by TDDFT-ECD calculations of their ECD spectra. All of the isolated compounds were tested for the inhibitory activity against angiotensin-I-converting enzyme (ACE), and compounds 1 and 2 displayed activity with IC50 values 3.10 and 11.28 μM, respectively. The intermolecular interaction and potential binding sites of 1 and 2 with ACE were elaborated by molecular docking, showing that compound 1 bound well with ACE via hydrogen interactions with residues Ala261, Gln618, Trp621, and Asn624, while compound 2 interacted with residues Asp358 and Tyr360.

Abstract
1H-Phenalen-1-one is a very efficient and easy-to-synthesize photosensitizer. Many substitutions have been previously described, but most of them significantly reduce the singlet oxygen quantum yield. The chloromethyl derivative described elsewhere is a good starting point for the synthesis of many useful derivatives because of the methylene bridge that saves its unique photosensitizing properties. Eighteen new phenalenone derivatives have been synthesized, bearing amine, carboxylic acid, alcohol, azide, and other major functional groups in organic chemistry. These reactions were carried out in good-to-excellent yields, and most of these new compounds retained the singlet oxygen quantum yield of the parent molecule. These new derivatives are very promising precursors for a number of applications such as the development of photosensitive antimicrobial agents or materials.

Abstract
Human neutrophil elastase (HNE) is a major cause of the destruction of tissues in cases of several different chronic andinflammatory diseases. Overexpression of the elastase enzyme plays a significant role in the pathogenesis of various diseases including chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome, rheumatoid arthritis, the rare disease cyclic hematopoiesis (or cyclic neutropenia), infections, sepsis, cystic fibrosis, myocardial ischemia/reperfusion injury and asthma, inflammation, and atherosclerosis. Human neutrophil elastase is secreted by human neutrophils due to different stimuli. Medicine-based inhibition of the over-activation of neutrophils or production and activity of elastase have been suggested to mend inflammatory diseases. Although the development of new elastase inhibitors is an essential strategy for treating the different inflammatory diseases, it has been a challenge to specifically target the activity of elastase because of its overlapping functions with those of other serine proteases. This review article highlights the reported natural polypeptides as potential inhibitors of elastase enzyme. The mechanism of action, structural features, and activity of the polypeptides have also been correlated wherever they were available.

Abstract
This review covers recent literature from 2012-2019 concerning 170 marine natural products and their semisynthetic analogues with strong anticancer biological activities. Reports that shed light on cellular and molecular mechanisms and biological functions of these compounds, thus advancing the understanding in cancer biology are also included. Biosynthetic studies and total syntheses, which have provided access to derivatives and have contributed to the proper structure or stereochemistry elucidation or revision are mentioned. The natural compounds isolated from marine organisms are divided into nine groups, namely: alkaloids, sterols and steroids, glycosides, terpenes and terpenoids, macrolides, polypeptides, quinones, phenols and polyphenols, and miscellaneous products. An emphasis is placed on several drugs originating from marine natural products that have already been marketed or are currently in clinical trials.

Abstract
Cultivation and extraction of the fungus Talaromyces stipitatus led to the isolation of five new oxyphenalenone-amino acid hybrids, which were named talauxins E, Q, V, L, and I based on the corresponding one-letter amino acid codes, along with their putative biosynthetic precursor, duclauxin. The rapid reaction of duclauxin with amino acids to produce talauxins was demonstrated in vitro and exploited to generate a small library of natural and unnatural talauxins. Talauxin V was shown to undergo spontaneous elimination of methyl acetate to yield the corresponding neoclauxin scaffold. This process was modeled using density functional theory calculations, revealing a dramatic change in conformation resulting from the syn elimination of methyl acetate.

Abstract
Two new phenalenone analogs hispidulones A (1) and B (2) were isolated from the specially bioenvironmental desert plant endophytic fungus Chaetosphaeronema hispidulum. The structure of these two compounds were elucidated by extensive spectra analysis including HR-ESI-MS, NMR (1H, 13C, 1H-1H COSY, HSQC, and HMBC), CD, and electronic circular dichroism (ECD) combined with quantum-chemical calculations adopting time-dependent density functional theory (TDDFT) approaches. The W long-ranged 1H-1H COSY and HMBC correlations are very important in the structural elucidation of these two compounds. Hispidulone A (1) possesses a cyclohexa-2,5-dien-1-one moiety, whereas hispidulone B (2) contains a hemiacetal OCH3 group, which are very rare in the structures of phenalenone analogs. According to structural features of these two compounds together considering the literature, the possible biosynthetic pathway of 1 and 2 was postulated. Hispidulone B (2) displayed cytotoxic activities against three cancer cell lines A549, Huh7, and HeLa with IC50 values of 2.71 ± 0.08, 22.93 ± 1.61, and 23.94 ± 0.33 μM.

Abstract
Plant endophytes are microorganisms that live in healthy plant tissues in part or all of their life history without causing obvious symptoms of infection in the host plants. Endophytes, a new type of microbial resource that can produce a variety of biological constituents, have great values for research and broad prospects for development. This article reviewed the research and development progress of endophytic fungi with cytotoxic activity between 2014 and 2017, including endophytic fungi sources, microbial taxonomy, compound classification and cytotoxic activity. The results showed that the 109 strains of endophytic fungi belong to 3 phyla, 7 classes and 50 genera. The secondary metabolites mainly contained alkaloids, terpenes, steroids, polyketides, quinones, isocoumarins, esters etc. The results of this study provide references for the development of new antitumor drugs and endophytes resources.

Abstract
Auxarthrones A-E (1-5), five new phenalenones, and two new naturally occurring cyclic tetrapeptides, auxarthrides A (7) and B (8), were obtained from three different solvent extracts of cultures of the coprophilous fungus Auxarthron pseudauxarthron. Auxarthrones C (3) and E (5) possess an unusual 7a,8-dihydrocyclopenta[a]phenalene-7,9-dione ring system that has not been previously observed in natural products. Formation of 1-5 was found to be dependent on the solvent used for culture extraction. The structures of these new compounds were elucidated primarily by analysis of NMR and MS data. Auxarthrone A (1) was obtained as a mixture of chromatographically inseparable racemic diastereomers (1a and 1b) that cocrystallized, enabling confirmation of their structures by X-ray crystallography. The absolute configurations of 7 and 8 were assigned by analysis of their acid hydrolysates using Marfey's method. Compound 1 displayed moderate antifungal activity against Cryptococcus neoformans and Candida albicans, but did not affect human cancer cell lines.
