Evaluation of the potential of endophytic Trichoderma sp. isolated from medicinal plant Ampelopsis japonica against MRSA and bioassay-guided separation of the anti-MRSA compound. Braz J Microbiol 2024; 55:543-556. [PMID: 38261262 PMCID: PMC10920522 DOI: 10.1007/s42770-024-01250-z] [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: 08/08/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024] Open
Abstract
Endophytic fungi have been recognized as a valuable source for the production of biologically active compounds with potential applications in various domains. This study aimed to isolate endophytic fungi from Ampelopsis japonica (Thunb.) Makino and assess their anti-MRSA activity. Meanwhile, chromatographic separation techniques were applied to analyze the constituents of endophytic fungal secondary metabolites. The isolate BLR24, which exhibited strong inhibition activity against MRSA, was identified as Trichoderma virens based on morphological characteristics and ITS sequence analyses. The ethyl acetate extract of BLR24 (EA-BLR24) showed good anti-MRSA activity with the MIC and MBC values of 25 μg/mL and 50 μg/mL, separately. The inhibition of biofilm formation was up to 34.67% under MIC concentration treatment. Meanwhile, EA-BLR24 could significantly reduce the expression of biofilm-related genes (icaA, sarA, and agrA) of MRSA. Based on LC-MS/MS analysis, twenty compounds in EA-BLR24 could be annotated using the GNPS platform, mainly diketopiperazines. The anti-MRSA compound (Fr.1.1) was obtained from EA-BLR24 by bioassay-guided fractionation and determined as gliotoxin. The results indicated that endophytic Trichoderma virens BLR24 isolated from the medical plant A. japonica roots could be a promising source of natural anti-MRSA agents. Endophytic fungal secondary metabolites are abundant in biologically active compounds. Endophytic fungi from medicinal plants could be a source yielding bioactive metabolites of pharmaceutical importance.

Abstract
The seminal discovery of paclitaxel from endophytic fungus Taxomyces andreanae was a milestone in recognizing the immense potential of endophytic fungi as prolific producers of bioactive secondary metabolites of use in medicine, agriculture, and food industries. Following the discovery of paclitaxel, the research community has intensified efforts to harness endophytic fungi as putative producers of lead molecules with anticancer, anti-inflammatory, antimicrobial, antioxidant, cardio-protective, and immunomodulatory properties. Endophytic fungi have been a valuable source of bioactive compounds over the last three decades. Compounds such as taxol, podophyllotoxin, huperzine, camptothecin, and resveratrol have been effectively isolated and characterized after extraction from endophytic fungi. These findings have expanded the applications of endophytic fungi in medicine and related fields. In the present review, we systematically compile and analyze several important compounds derived from endophytic fungi, encompassing the period from 2011 to 2022. Our systematic approach focuses on elucidating the origins of endophytic fungi, exploring the structural diversity and biological activities exhibited by these compounds, and giving special emphasis to the pharmacological activities and mechanism of action of certain compounds. We highlight the tremendous potential of endophytic fungi as alternate sources of bioactive metabolites, with implications for combating major global diseases. This underscores the significant role that fungi can play in the discovery and development of novel therapeutic agents that address the challenges posed by prevalent diseases worldwide.

In Vitro Efficacy of Extracts and Isolated Bioactive Compounds from Ascomycota Fungi in the Treatment of Colorectal Cancer: A Systematic Review. Pharmaceuticals (Basel) 2022; 16:ph16010022. [PMID: 36678519 PMCID: PMC9864996 DOI: 10.3390/ph16010022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/15/2022] [Accepted: 12/18/2022] [Indexed: 12/28/2022] Open
Abstract
Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. Despite the advances and success of current treatments (e.g., chemotherapy), there are multiple serious side effects which require the development of new treatment strategies. In recent years, fungi have gained considerable attention as a source of extracts and bioactive compounds with antitumor capabilities because of their antimicrobial and antioxidant properties and even their anti-inflammatory and antiviral activities. In the present review, a systematic search of the existing literature in four electronic databases was carried out in which the antitumor activity against CRC cells of Ascomycota fungi extracts or compounds was tested. The systematical research in the four databases resulted in a total of 883 articles. After applying exclusion and inclusion criteria, a total of 75 articles were finally studied. The order Eurotiales was the most studied (46% of the articles), and the ethyl acetate extraction was the most used method (49% of the papers). Penicillium extracts and gliotoxin and acetylgliotoxin G bioactive compounds showed the highest cytotoxic activity. This review also focuses on the action mechanisms of the extracts and bioactive compounds of fungi against CRC, which were mediated by apoptosis induction and the arrest of the cell cycle, which induces a notable reduction in the CRC cell proliferation capacity, and by the reduction in cell migration that limits their ability to produce metastasis. Thus, the ability of fungi to induce the death of cancer cells through different mechanisms may be the basis for the development of new therapies that improve the current results, especially in the more advanced stages of the CCR.

Abstract
The endophytic fungi that reside inside medicinal plants have the potential to produce various pharmaco-potential bioactive compounds. The endophytic fungi Graminicolous helminthosporium, Bipolaris australiensis and Cladosporium cladosporioides were isolated from different medicinal plants. The GC-MS analysis of intra- and extracellular products of endophytic fungi revealed the presence of various bioactive metabolites, such as Anthracene, Brallobarbital, Benzo [h] quinolone, Ethylacridine, 2-Ethylacridine, Cyclotrisiloxane, 5 methyl 2 phenylindolizine, and 1,4-Cyclohexadien-1-one, etc. The phytochemical composition analysis of endophytic fungus extracts also revealed the presence of flavonoids, phenols, saponins, carbohydrates, glycosides, and proteins. The intra- and extracellular endophytic extracts exhibited strong antibacterial and antioxidant activity, which was screened with the agar-well diffusion method and DPPH, H2O2, and nitric oxide scavenging activity, respectively. The bioactive compounds identified in the endophytic extracts from GC-MS profiling served as ligands for molecular-docking analysis to investigate the anticancer potential against non-small cell lung carcinoma receptor EGFR. Molecular docking results showed that compounds, such as Brallobarbital, and 5 methyl 2 phenylindolizine had the lowest E- min values, which suggests that these compounds could be used in anticancer drug development. Thus, the isolated endophytic fungal species can be used to produce various bioactive compounds that could be used in novel drug development from natural sources and reduce the environmental burden of synthetic chemical drugs.

Abstract
Aspergillus versicolor, a widely distributed fungus, is associated with pollution and carcinogenic hazards. This study aimed to examine the functions of the A. versicolor exudate and laid a scientific foundation for improving our understanding, utilization, and control of A. versicolor. The A. versicolor exudate proteome, ion content, and amino acid components were determined using label-free quantitation, atomic absorption spectrophotometry, and high-performance liquid chromatography, respectively. In total, 502 proteins were identified in the A. versicolor exudate. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and cluster of orthologous group analyses were used to annotate the functional classification and pathways of the aligned proteins. Proteins identified in the exudate were mainly enriched in carbohydrate metabolic process, translation, oxidoreductase activity, oxidoreductase activity, hydrolase activity, cell wall-related processes, catalytic activity, and unknown functions. The exudate comprised Na, K, Ca, Fe, and Mg cations. Among the 17 types of amino acids detected in the exudate, 7 were essential and 10 were nonessential. The exudate may be involved in the vital processes of A. versicolor. Additionally, the exudate may play an important role in the growth, development, reproduction, homeostasis, nutrient supply for regrowth, and virulence of A. versicolor.

Abstract
The inorganic selenium is absorbed and utilized inefficiently, and the range between toxicity and demand is narrow, so the application is strictly limited. Selenium nanoparticles have higher bioactivity and biosafety properties, including increased antioxidant and anticancer properties. Thus, producing and applying eco-friendly, non-toxic selenium nanoparticles in feed additives is crucial. Bacillus paralicheniformis Y4 was investigated for its potential ability to produce selenium nanoparticles and the activity of carboxymethyl cellulases. The selenium nanoparticles were characterized using zeta potential analyses, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). Additionally, evaluations of the anti-α-glucosidase activity and the antioxidant activity of the selenium nanoparticles and the ethyl acetate extracts of Y4 were conducted. B. paralicheniformis Y4 exhibited high selenite tolerance of 400 mM and the selenium nanoparticles had an average particle size of 80 nm with a zeta potential value of −35.8 mV at a pH of 7.0, suggesting that the particles are relatively stable against aggregation. After 72 h of incubation with 5 mM selenite, B. paralicheniformis Y4 was able to reduce it by 76.4%, yielding red spherical bio-derived selenium nanoparticles and increasing the carboxymethyl cellulase activity by 1.49 times to 8.96 U/mL. For the first time, this study reports that the carboxymethyl cellulase activity of Bacillus paralicheniforis was greatly enhanced by selenite. The results also indicated that B. paralicheniformis Y4 could be capable of ecologically removing selenite from contaminated sites and has great potential for producing selenium nanoparticles as feed additives to enhance the added value of agricultural products.

Abstract
The present study focuses on antioxidant, antibacterial, phytochemical potential, and cytotoxicity of secondary metabolites from Colletotrichum gloeosporioides, Fusarium proliferatum, Alternaria arborescens, and Pestalotiopsis vismiae. The scavenging effect of fungal metabolites was determined by 2, 2-diphenyl-1-picrylhydrazyl (DPPH), H2 O2 , O2 -, and reducing power assays. Among the four fungi, A. arborescens have higher antioxidant activity of DPPH (81.12%), H2 O2 (74.83%), superoxide (75.74%), and reducing power (0.141) with standard ascorbic acid. Fungal metabolites were found to be significantly effective against all tested pathogens. A. arborescens showed significant amounts of phenolic (138.78 ± 3.70 mg/g of gallic acid equivalent), flavonoid (74.16 ± 3.58 mg/g of quercetin equivalent), as well as cytotoxicity effects in a cancer cell line (A549) with inhibitory concentration (IC50 = 35 µg/ml at 24 and 48 h). The live and dead cells were analyzed by acridine orange/ethidium bromide staining methods. In addition, A. arborescens metabolites were characterized through gas chromatography-mass spectrometry analysis. The major compounds were found to be phenol, 4-(1,1,3,3-tetramethylbutyl)-, acetamide, N-(3-methylphenyl)-, dibutyl phthalate, and benzo[qr]naphtho[2,1,8,7-fghi] pentacene. The compounds were reported in A. arborescensis up to our knowledge this is the first report. Based on this study, all fungal strains have a significant bioactive capacity with A. arborescens strain exhibiting greater biological properties. Further purification and characterization of A. arborescens bioactive component could lead to an intriguing reservoir of novel pharmacological agents in the future.

Hagag AH, Abdelwahab MF, Abd El-Kader AM, Fouad MA. The Endophytic Aspergillus Strains: A Bountiful Source of Natural Products. J Appl Microbiol 2022; 132:4150-4169. [PMID: 35157354 DOI: 10.1111/jam.15489] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/27/2022] [Accepted: 02/09/2022] [Indexed: 11/29/2022]
Abstract
Fungi that invade plant inner tissues without inducing disease symptoms are known as fungal endophytes. They represent a promising and tremendous reservoir of natural products with valuable biological potentials for application in medicine, agriculture and industry. Among the numerous existing endophytic fungi, Aspergillus strains constitute one of the most prolific sources of secondary metabolites with diverse chemical classes and interesting biological activities. This review covers the literature of the year 2020, reporting the isolation of 202 compounds obtained from more than ten different endophytic Aspergillus species associated with different host plants. Analysis and interpretation of the collected data revealed that chemical investigation of endophytes belonging to the genus Aspergillus may greatly contribute in the discovery of potential drug leads. The isolated metabolites were chemically various and exhibited diverse biological activities such as antibacterial, anti-cancer, anti-plasmodial, anti-inflammatory, antioxidant, immunosuppressive and antifungal activities. Moreover, adoption of advanced technology in molecular biology together with modern chemical tools is anticipated to improve the discovery of new biopharmaceuticals from this valuable microbial world in the future.

Abstract
BACKGROUND Many groups of fungi live as an endophyte in plants. Both published and undiscovered bioactive compounds can be found in endophytic fungi. Various biological activities of bioactive compounds from endophytic fungi had been reported, including anti-inflammatory and anticancerous effects. The chemical investigation of biologically active compounds from endophytic fungi Melaleuca leucadendra Linn. have not yet been stated. RESULTS One new compound, namely nigaurdiol (1), along with five known compounds, xyloketal K (2), bostrycin (3), deoxybostrycin (4), xylanthraquinone (5), and ergosterol (6), were isolated from the Melaleuca leucadendra Linn. associated fungal strain Nigrospora aurantiaca #TMU062. Their chemical structures were elucidated by spectroscopic data and compared with literature. All isolated compounds were evaluated for inhibitory effect of NO production in LPS-activated microglial BV-2 cells. CONCLUSIONS Compound 6 exhibited considerable inhibitory effect on NO production with IC50 values of 7.2 ± 1.4 µM and the survival rate of the cells was 90.8 ± 6.7% at the concentration of 10 µM.
