Abstract
Alzheimer's disease (AD) is an important human disease that mainly causes cognitive impairments. Growing evidence has shown that amyloid-β (Aβ) peptide plays a key role in AD pathogenesis in what is known as the Aβ cascade hypothesis. This hypothesis suggests the importance of suppressing Aβ aggregation and Aβ production. The latter process is governed by β-site APP Cleaving Enzyme1 (BACE1) and γ-secretase. We, therefore, focused on Aβ aggregation inhibitory activity, initially assessing numerous extracts derived from our marine-derived fungus collections. One EtOAc extract derived from an Aspergillus sp. exhibited Aβ aggregation inhibitory activity. Eleven known compounds (1-11) were isolated from CHCl3 and EtOAc extracts derived from the fungus, and the structures were identified based on MS, NMR, and ECD spectra. Compounds 2, 6, and 10 inhibited Aβ aggregation with IC50 values of 2.8, 3.9, and 8.1 μM, respectively. The protective effect on SH-SY5Y cells against Aβ toxicity was also evaluated, and compounds 6 and 10 significantly alleviated Aβ toxicity. BACE1 inhibitory activity was also examined, and compounds 4, 5, 7, 10, and 11 inhibited BACE1 activity with IC50 values of 14.9, 70.0, 36.5, 28.0, and 72.8 μM, respectively. These data suggest that compound 10 could be useful in AD treatment.

Abstract
Due to the negative environmental and health effects of synthetic colorants, pigments of natural origins of plants and microbes constitute an abundant source for the food, cosmetic, textile, and pharmaceutical industries. The demands for natural alternatives, which involve natural colorants and natural biological processes for their production, have been growing rapidly in recent decades. Fungi contain some of the most prolific pigment producers, and they excel in bioavailability, yield, cost-effectiveness, and ease of large-scale cell culture as well as downstream processing. In contrast, pigments from plants are often limited by seasonal and geographic factors. Here, we delineate the taxonomy of pigmented fungi and fungal pigments, with a focus on the biosynthesis of four major categories of pigments: carotenoids, melanins, polyketides, and azaphilones. The molecular mechanisms and metabolic bases governing fungal pigment biosynthesis are discussed. Furthermore, we summarize the environmental factors that are known to impact the synthesis of different fungal pigments. Most of the environmental factors that enhance fungal pigment production are related to stresses. Finally, we highlight the challenges facing fungal pigment utilization and future trends of fungal pigment development. This integrated review will facilitate further exploitations of pigmented fungi and fungal pigments for broad applications.

Abstract
Amid the current COVID-19 pandemic, the emergence of several variants in a relatively high mutation rate (twice per month) strengthened the importance of finding out a chemical entity that can be potential for developing an effective medicine. In this study, we explored ethyl acetate (EtOAc) extract of a marine-derived fungus Aspergillus cosatricaensis afforded three butenolide derivatives, butyrolactones I, VI and V (1-3), two naphtho-γ-pyrones, TMC-256 A1 (4) and rubrofusarin B (5) and methyl p-hydroxyphenyl acetate (6). Structure identification was unambiguously determined based on exhaustive spectral analyses including 1D/2D NMR and mass spectrometry. The isolated compounds (1-6) were assessed for their in vitro anti-inflammatory, antiallergic, elastase inhibitory activities and in silico SARS-CoV-2 main protease (Mpro). Results exhibited that only butenolides (1 and 2) revealed potent activities similar to or more than reference drugs unlike butyrolactone V (3) suggesting them as plausible chemical entities for developing lead molecules.

Abstract
Chemotherapy resistance is one of the main causes of lung cancer treatment failure, and a combination regimen may be an effective way to overcome this. Here we report 5 new (1-3, 7, and 9) and 15 known polyketides, isolated from an endozoic Aspergillus niger. The structures of the new compounds were determined by the interpretation of IR, HRESIMS, NMR, and ECD spectra. The ESI-MS/MS fragmentation of the isolated naphtho-γ-pyrone isomers in positive mode is discussed. The effects of isolated compounds in combination with cisplatin (DDP) on a DDP-resistant A549 cell line (A459/DDP) are investigated. The most active compound, 12, could reduce the ratio of GSH/GSSG, promote the generation of intracellular ROS, and cooperate with DDP to down-regulated levels of Nrf2, Akt, HO-1, and NQO1, suggesting that inhibition of Nrf2 and Akt pathways might be involved in the combined effect of 12 and DDP in A549/DDP cells.

Abstract
Fungi can produce myriad secondary metabolites, including pigments. Some of these pigments play a positive role in human welfare while others are detrimental. This paper reviews the types and biosynthesis of fungal pigments, their relevance to human health, including their interactions with host immunity, and recent progresses in their structure-activity relationships. Fungal pigments are grouped into carotenoids, melanin, polyketides, and azaphilones, etc. These pigments are phylogenetically broadly distributed. While the biosynthetic pathways for some fungal pigments are known, the majority remain to be elucidated. Understanding the genes and metabolic pathways involved in fungal pigment synthesis is essential to genetically manipulate the production of both the types and quantities of specific pigments. A variety of fungal pigments have shown wide-spectrum biological activities, including promising pharmacophores/lead molecules to be developed into health-promoting drugs to treat cancers, cardiovascular disorders, infectious diseases, Alzheimer's diseases, and so on. In addition, the mechanistic elucidation of the interaction of fungal pigments with the host immune system provides valuable clues for fighting fungal infections. The great potential of fungal pigments have opened the avenues for academia and industries ranging from fundamental biology to pharmaceutical development, shedding light on our endeavors for disease prevention and treatment.

Abstract
It is generally accepted that fungi have a number of dormant gene clusters for the synthesis of secondary metabolites, and the activation of these gene clusters can expand the diversity of secondary metabolites in culture. Recent studies have revealed that the mycolic acid-containing bacterium Tsukamurella pulmonis activates dormant gene clusters in the bacterial genus Streptomyces. However, it is not clear whether the mycolic acid-containing bacteria activate dormant gene clusters of fungi. We performed co-culture experiments using marine-derived Aspergillus niger with Mycobacterium smegmatis, a mycolic acid-containing bacteria. The co-cultivation resulted in the production of a pigment by A. niger and increased cytotoxic activity of the extract against human prostate cancer DU145 cells. An analysis of secondary metabolites in the extract of the co-culture broth revealed that the increase in cytotoxic activity was caused by the production of malformin C (1), and that TMC-256A1 (2), desmethylkotanin (3), and aurasperone C (4) were selectively produced under co-culture conditions. In addition, further study suggested that direct interaction between the two microorganisms was necessary for the production of the pigment and the cytotoxic compound malformin C (1) from A. niger. Given the biological activities of malformin C, including cytotoxic activity, our approach for increasing the production of bioactive secondary metabolites has important practical applications and may facilitate structural analyses of novel bioactive compounds.

Abstract
Capillasterin A (1), a novel pyrano[2,3-f]chromene, together with seven known naphthopyrones including comaparvin (2), TMC-256C1 (3), 6-methoxycomaparvin-5- methyl ether (4), 5,8-dihydroxy-6-methoxy-2-propyl-4H-naphtho[2,3-b]pyran-4-one (5), 5,8-dihydroxy-6,10-dimethoxy-2-propyl-4H-naphtho[2,3-b]pyran-4-one (6), TMC-256A1 (7) and 6-methoxycomaparvin (8) were isolated from an EtOH/H2O extract from the Australian crinoid Capillaster multiradiatus. The structures of all the compounds were determined by detailed spectroscopic (1D/2D NMR and MS) data analysis. This is the first report of a natural product that contains the pyrano[2,3-f]chromene skeleton. Compounds 2–6 were observed to display moderate inhibition of in vitro HIV-1 replication in a T cell line with EC50 values ranging from 7.5 to 25.5 µM without concomitant cytotoxicity.

Abstract
The addition of metal bromides (NaBr and CaBr2) during fermentation of the marine-mudflat-derived fungus Aspergillus niger induced production of a new radical scavenging brominated naphthopyranone, 6,9-dibromoflavasperone (1); and three known naphtho-γ-pyranone monomers, flavasperone (2), TMC-256A1 (3), and fonsecin (4); and one naphtho-γ-pyranone dimer, aurasperone B (5). The structure of 6,9-dibromoflavasperone (1) was assigned through the combination of spectroscopic data analyses and comparison with the spectral data of flavasperone (2). Compounds 1-5 displayed potent radical scavenging activity against 2,2-diphenyl-1-picrylhydrazyl, with IC50 values of 21, 25, 0.3, 0.02, and 0.01 μM, respectively, and 3-5 were more potent than the positive control, ascorbic acid (IC50, 20.0 μM).

Anti-Inflammatory and Cytoprotective Effects of TMC-256C1 from Marine-Derived Fungus Aspergillus sp. SF-6354 via up-Regulation of Heme Oxygenase-1 in Murine Hippocampal and Microglial Cell Lines. Int J Mol Sci 2016; 17:529.

Abstract
In the course of searching for bioactive secondary metabolites from marine fungi, TMC-256C1 was isolated from an ethyl acetate extract of the marine-derived fungus Aspergillus sp. SF6354. TMC-256C1 displayed anti-neuroinflammatory effect in BV2 microglial cells induced by lipopolysaccharides (LPS) as well as neuroprotective effect against glutamate-stimulated neurotoxicity in mouse hippocampal HT22 cells. TMC-256C1 was shown to develop a cellular resistance to oxidative damage caused by glutamate-induced cytotoxicity and reactive oxygen species (ROS) generation in HT22 cells, and suppress the inflammation process in LPS-stimulated BV2 cells. Furthermore, the neuroprotective and anti-neuroinflammatory activities of TMC-256C1 were associated with upregulated expression of heme oxygenase (HO)-1 and nuclear translocation of nuclear factor-E2-related factor 2 (Nrf2) in HT22 and BV2 cells. We also found that TMC-256C1 activated p38 mitogen-activated protein kinases (MAPK) and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways in HT22 and BV2 cells. These results demonstrated that TMC-256C1 activates HO-1 protein expression, probably by increasing nuclear Nrf2 levels via the activation of the p38 MAPK and PI3K/Akt pathways.

Abstract
Aspergillus awamori was isolated from a diseased banana fruit, Musa acuminata cv. Ambul. The fungus was fermented in potato dextrose broth and on potato dextrose agar media and the fungal media were extracted with EtOAc. Chromatographic separation of the EtOAc extracts furnished 4-methoxybenzyl 7-phenylacetamido-3-vinyl-3-cephem-4-carboxylate (1), along with three naphtho-γ-pyrones, flavasperone (2), foncesinone A (3) and aurasperone A (4), and three alkaloids, aspernigrin A (5), pestalamide C (6) and nigragillin (7). Compound 1, a known key intermediate in the chemical synthesis of cepham antibiotics, was isolated from a natural source for the first time. Compound 1 is the first 3-vinyl cephem derivative of microbial origin.

Five new naphthopyrones (1-5) along with the known compounds TMC-256A1, 5,8-dihydroxy-6-methoxy-2-propyl-4H-naphtho[2,3-b]pyran-4-one, TMC-256C1, comaparvin, 6-methoxycomaparvin, and 6-methoxycomaparvin 5-methyl ether (6-11) were isolated from crinoids of the family Comasteridae. All compounds were tested for their ability to inhibit the multidrug transporter ABCG2, which plays a role in drug resistance. Six of the seven angular naphthopyrones showed moderate activity with <60% inhibition of ABCG2-mediated transport as compared to the positive control fumitremorgin C. None of the linear naphthopyrones inhibited ABCG2-mediated efflux.

Abstract
Filamentous fungi in the Aspergillus section Nigri (the black aspergilli) represent some of the most widespread food and feed contaminants known but they are also some of the most important workhorses used by the biotechnological industry. The Nigri section consists of six commonly found species (excluding A. aculeatus and its close relatives) from which currently 145 different secondary metabolites have been isolated and/or detected. From a human and animal safety point of view, the mycotoxins ochratoxin A (from A. carbonarius and less frequently A. niger) and fumonisin B(2) (from A. niger) are currently the most problematic compounds. Especially in foods and feeds such as coffee, nuts, dried fruits, and grape-based products where fumonisin-producing fusaria are not a problem, fumonisins pose a risk. Moreover, compounds such as malformins, naptho-gamma-pyrones, and bicoumarins (kotanins) call for monitoring in food, feed, and biotechnology products as well as for a better toxicological evaluation, since they are often produced in large amounts by the black aspergilli. For chemical differentiation/identification of the less toxic species the diketopiperazine asperazine can be used as a positive marker since it is consistently produced by A. tubingensis (177 of 177 strains tested) and A. acidus (47 of 47 strains tested) but never by A. niger (140 strains tested). Naptho-gamma-pyrones are the compounds produced in the highest quantities and are produced by all six common species in the group (A. niger 134 of 140; A. tubingensis 169 of 177; A. acidus 44 of 47; A. carbonarius 40 of 40, A. brasiliensis 18 of 18; and A. ibericus three of three).

Abstract
A survey on the occurrence on grape of fungi species in 2001 and their capability to produce ochratoxin A (OTA) and naphtho-gamma-pyrones (NGPs) was conducted in different vineyards from several French viticulture regions. The total numbers of fungal isolates, from setting to harvest, were 732. The Aspergillus genus was essentially represented by section Nigri (98.53%) and it was predominant (74.72%) when compared to Penicillium (25.27%). Approximately one third (30.46%) of the fungal isolates were OTA producers, and 94.17% belong to black aspergilli; Aspergillus carbonarius was the main OTA producer. Moreover, 8.33% of isolates (belong to A. carbonarius and A. niger) were NGP producers. However, none of the Penicillium spp. or other Aspergillus spp. isolates can produces NGP derivatives under the conditions used. No other study on NGPs production by fungi isolated from grapes has been reported. In the second part, a novel NGP, named aurasperone G (1), was isolated from the fermentation broth of the culture extracts of Aspergillus niger C-433, strain producer of OTA, along with the known compound aurasperone F (2). The chemical structure of the new polyketide was proposed based on complete (1)H and partial (13)C, COSY, HMQC, 1D NOE NMR spectra as well as UV and MS spectra. This new NGP was not reported before in nature or prepared synthetically.

Abstract
Hypoxia-inducible factor-1 (HIF-1) is a transcription factor that promotes tumor cell adaptation and survival under hypoxic conditions. HIF-1 is currently recognized as an important molecular target for anticancer drug discovery. The National Cancer Institute open repository of marine invertebrates and algae lipid extracts was evaluated using a T47D breast tumor cell-based reporter assay for HIF-1 inhibitory activity. Bioassay-guided fractionation of an active extract from a crinoid Comantheria rotula yielded seven benzo[g]chromen-4-one and benzo[h]chromen-4-one pigments (1-7). The structures of the new benzo[g]chromenone dimer 9,9'-oxybis-neocomantherin (1) and another new natural pigment 5 were deduced from spectroscopic and spectrometric data. The crinoid pigments significantly inhibited both hypoxia-induced and iron chelator-induced HIF-1 luciferase reporter activity in breast and prostate tumor cells. However, inhibition of HIF-1 in the reporter assay did not translate into a significant decrease in the expression of the downstream HIF-1 target, secreted vascular endothelial growth factor (VEGF). Compound 1 was found to inhibit tumor cell growth in the NCI 60-cell line panel (GI(50) values of 1.6-18.2 microM), and compound 6 produced a unique pattern of tumor cell growth suppression. Five cell lines from different organs were hypersensitive to 6 (GI(50) values of 0.29-0.62 microM), and three others were moderately sensitive (GI(50) values of 2.2-5.1 microM), while the GI(50) values for most other cell lines ranged from 20 to 47 microM. Crinoid benzo[g]chromenones were also found to scavenge radicals in a modified DPPH assay.

Abstract
Three new naphtho-gamma-pyrones, 5-hydroxy-6,8-dimethoxy-2-hydroxymethyl-4H-naphtho[2,3-b]pyran-4-one (1, nigerasperone A), 3,3'-dihydro-2,2',5,5'-tetrahy-droxy-8,8',10,10'- tetramethoxy-2,2'-dimethyl-(6',9-bi-4H-naphtho[1,2-b]pyran)-4,4'-dione (2, nigerasperone B), and 3'-hydro-2',5,5',8-tetrahydroxy-6,6',8'-trimethoxy-2,2'-dimethyl-(7,10'-bi-4H-naphtho[2,3-b]pyran)-4,4'-dione (3, nigerasperone C), together with nine related known compounds were characterized from Aspergillus niger EN-13, an endophytic fungus isolated from the marine brown alga Colpomenia sinuosa. Their structures were elucidated by detailed analysis of spectroscopic data and by comparison with literature reports. In the cytotoxic assay, these compounds did not show remarkable inhibitory effects against A549 and SMMC-7721 tumor cell lines. However, 3 and several known compounds showed weak antifungal activity against Candida albicans and moderate activity on DPPH scavenging.

Abstract
Fractionation of the extract of Aspergillus niger. IFB-E003, an endophyte in Cyndon dactylon, gave four known compounds naphtho-gamma-pyrones rubrofusarin B, fonsecinone A, asperpyrone B and aurasperone A, which were further investigated biologically. Rubrofusarin B was shown to be cytotoxic to the colon cancer cell line SW1116 (IC50: 4.5 microgml-1), and aurasperone A inhibitory on XO (xanthine oxidase) (IC50: 10.9 micromoll-1). Moreover, the four naphtho-gamma-pyrones exhibited growth inhibitions against the five test microbes with MICs ranging in between 1.9 and 31.2 microgml(-1). The present recognition of rubrofusarin B and aurasperone A as strong co-inhibitors on XO, colon cancer cell and some microbial pathogens is of significance for the imperative discovery of new relevant therapeutic agents.
