Meroterpenoids from the marine-derived fungus Aspergillus terreus GZU-31-1 exerts anti-liver fibrosis effects by targeting the Nrf2 signaling in vitro. PHYTOCHEMISTRY 2024; 219:113983. [PMID: 38215814 DOI: 10.1016/j.phytochem.2024.113983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 01/09/2024] [Accepted: 01/09/2024] [Indexed: 01/14/2024]
Abstract
Six undescribed meroterpenoids aspertermeroterpenes A-F and four known analogues were isolated from the marine-derived fungus Aspergillus terreus GZU-31-1. Their structures were elucidated based on spectroscopic methods and electronic circular dichroism calculations. All meroterpenoids possessed the unique acetyl group at C-11, and also aspertermeroterpene A featured the rare C-14 decarboxylated in DMOA meroterpenoids. In the bioassays, aspermeroterpene B exhibited a potent inhibitory effect on the activation of hepatic stellate cells at the concentration of 5 μM via targeting the Nrf2 signaling. This is the first time reported that aspermeroterpene B as a previously undescribed carbon skeleton of meroterpenoid possessed anti-liver fibrosis effect.

Abstract
Alzheimer's disease (AD) is the most common form of dementia. It increases the risk of other serious diseases and causes a huge impact on individuals, families, and socioeconomics. AD is a complex multifactorial disease, and current pharmacological therapies are largely based on the inhibition of enzymes involved in the pathogenesis of AD. Natural enzyme inhibitors are the potential sources for targeting AD treatment and are mainly collected from plants, marine organisms, or microorganisms. In particular, microbial sources have many advantages compared to other sources. While several reviews on AD have been reported, most of these previous reviews focused on presenting and discussing the general theory of AD or overviewing enzyme inhibitors from various sources, such as chemical synthesis, plants, and marine organisms, while only a few reviews regarding microbial sources of enzyme inhibitors against AD are available. Currently, multi-targeted drug investigation is a new trend for the potential treatment of AD. However, there is no review that has comprehensively discussed the various kinds of enzyme inhibitors from the microbial source. This review extensively addresses the above-mentioned aspect and simultaneously updates and provides a more comprehensive view of the enzyme targets involved in the pathogenesis of AD. The emerging trend of using in silico studies to discover drugs concerning AD inhibitors from microorganisms and perspectives for further experimental studies are also covered here.

Abstract
Meroterpenoids are natural products synthesized by unicellular organisms such as bacteria and multicellular organisms such as fungi, plants, and animals, including those of marine origin. Structurally, these compounds exhibit a wide diversity depending upon the origin and the biosynthetic pathway they emerge from. This diversity in structural features imparts a wide spectrum of biological activity to meroterpenoids. Based on the biosynthetic pathway of origin, these compounds are either polyketide-terpenoids or non-polyketide terpenoids. The recent surge of interest in meroterpenoids has led to a systematic screening of these compounds for many biological actions. Different meroterpenoids have been recorded for a broad range of operations, such as anti-cholinesterase, COX-2 inhibitory, anti-leishmanial, anti-diabetic, anti-oxidative, anti-inflammatory, anti-neoplastic, anti-bacterial, antimalarial, anti-viral, anti-obesity, and insecticidal activity. Meroterpenoids also possess inhibitory activity against the expression of nitric oxide, TNF- α, and other inflammatory mediators. These compounds also show renal protective, cardioprotective, and neuroprotective activities. The present review includes literature from 1999 to date and discusses 590 biologically active meroterpenoids, of which 231 are from fungal sources, 212 are from various species of plants, and 147 are from marine sources such as algae and sponges.

Abstract
A new meroterpenoid, taladrimanin A (1), was isolated from a marine-derived fungus Talaromyces sp. HM6-1-1, together with eleven biogenetically related compounds (2-12). A plausible biosynthetic pathway for the meroterpenoids (1-4) was proposed. The planar structure of 1 was assigned by HRESIMS and NMR. Its relative configuration was established by quantum chemical NMR calculation of two possible isomers and analyzed by DP4 + method. Finally, X-ray diffraction unambiguously confirmed the relative configuration and revealed the absolute configuration of compound 1. 2-12 were assigned by comparing their NMR data with those reported in the literature. 1 was the first drimane-type meroterpenoid with a C10 polyketide unit bearing an 8R-configuration. In the bioactive assay, 1 exhibited antitumor activity against gastric cancer cells MGC803 and MKN28; it also inhibited the colony formation and induced apoptosis in MGC803 cells both in a concentration-dependent manner. Additionally, 1 displayed selective antibacterial activity against Staphylococcus aureus 6538P, and low activities towards strains of Vibrio parahaemolyticus and Escherichia coli in this study. KEY POINTS: • Twelve compounds were obtained from Talaromyces sp., including four meroterpenoids, one of which was new. • The new compound taladrimanin A (1) inhibits the growth of gastric cancer cells MGC803 and MKN28 as well as the pathogenic bacteria Staphylococcus aureus 6538P. • The biosynthetic pathway of the meroterpenoids was proposed.

Abstract
Fungal meroterpenoids are secondary metabolites from mixed terpene-biosynthetic origins. Their intriguing chemical structural diversification and complexity, potential bioactivities, and pharmacological significance make them attractive targets in natural product chemistry, organic synthesis, and biosynthesis. This review provides a systematic overview of the isolation, chemical structural features, biological activities, and fungal biodiversity of 1585 novel meroterpenoids from 79 genera terrestrial and marine-derived fungi including macrofungi, Basidiomycetes, in 441 research papers in 2009-2019. Based on the nonterpenoid starting moiety in their biosynthesis pathway, meroterpenoids were classified into four categories (polyketide-terpenoid, indole-, shikimate-, and miscellaneous-) with polyketide-terpenoids (mainly tetraketide-) and shikimate-terpenoids as the primary source. Basidiomycota produced 37.5% of meroterpenoids, mostly shikimate-terpenoids. The genera of Ganoderma, Penicillium, Aspergillus, and Stachybotrys are the four dominant producers. Moreover, about 56% of meroterpenoids display various pronounced bioactivities, including cytotoxicity, enzyme inhibition, antibacterial, anti-inflammatory, antiviral, antifungal activities. It's exciting that several meroterpenoids including antroquinonol and 4-acetyl antroquinonol B were developed into phase II clinically used drugs. We assume that the chemical diversity and therapeutic potential of these fungal meroterpenoids will provide biologists and medicinal chemists with a large promising sustainable treasure-trove for drug discovery.

Abstract
One new 3,5-dimethylorsellinic acid (DMOA)-based meroterpenoid (1), one prenylated tryptophan derivative (2), together with ten known compounds (3-12) were isolated from the endophytic fungus Aspergillus sp. from Tripterygium wilfordii. Their structures and absolute configurations were determined by NMR spectroscopic data, HRESIMS data, UV and IR data as well as electronic circular dichroism (ECD) calculation. In structure, compound 1 was a rare example of DMOA-based meroterpenoid with a cis-fused C/D ring system, and compound 2 possessed an unusual (E)-oxime group. In bioactivity, the lovastatin analogues 5, 6, 9 and 10 showed potential immunosuppressive activity against anti-CD3/anti-CD28 monoclonal antibodies (mAbs)-irritated murine splenocytes proliferation, with IC50 values ranging from (5.30 ± 0.51) μM to (16.51 ± 1.62) μM.

Meroterpenoids produced by fungi: Occurrence, structural diversity, biological activities, and their molecular targets. Eur J Med Chem 2020; 209:112860. [PMID: 33032085 DOI: 10.1016/j.ejmech.2020.112860] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 09/17/2020] [Accepted: 09/17/2020] [Indexed: 12/27/2022]
Abstract
Meroterpenoids are partially derived from the terpenoids, distributing widely in the plants, animals and fungi. The complex structures and diverse bioactivities of meroterpenoids have attracted more attention for chemists and pharmacologists. Since the first review summarized by Geris in 2009, there are absent of systematic reviews reported about meroterpenoids from the higher and lower fungi up to now. In the past decades, myriads of meroterpenoids were discovered, and it is necessary to summarize these meroterpenoids about their unique structures and promising bioactivities. In this review, we use a new classification method based on the non-terpene precursors, and also highlight the structural features, bioactivity of natural meroterpenoids from the higher and lower fungi covering the period of September 2008 to February 2020. A total of 709 compounds were discussed and cited the 182 references. Meanwhile, we also primarily summarize their occurrence, structural diversity, biological activities, and molecular targets.

Abstract
Terreuspyridine (1), the first 3,5-demethylorsellinic acid (DMOA) derived meroterpenoid alkaloid, was isolated from the fungus Aspergillus terreus, which represents a new type of meroterpenoid possessing an unexpected tetracyclic 6/6/6/6 architecture. The structure of 1 with absolute configuration was determined by X-ray diffraction analysis. Biogenetically, it was proposed to be derived from the fusion of a DMOA-meroterpenoid and a glutamate. Terreuspyridine (1) exhibited moderate inhibitory activity against the BChE with an IC50 value of 16.4 μM.

Abstract
Reports on β-secretase inhibitors of natural origin are listed in order to reveal their chemical diversity. Various types of compounds were found to inhibit β-secretase, and natural resources included a wide spectrum of biological species. Among them, some triterpenes and moracin derivatives, which are nonpeptidic compounds, were determined to be competitive inhibitors. In addition, no peptide compounds were reported from natural resources. These points will be clarified in future studies.

Abstract
Spiroterreusnoids A-F, six undescribed spiro-dioxolane-containing adducts bearing 3,5-dimethylorsellinic acid-based meroterpenoid and 2,3-butanediol moieties were isolated from the endophytic fungus Aspergillus terreus Thom from Tripterygium wilfordii Hook. f. (Celastraceae). The structures of these adducts were established by spectroscopy, single-crystal X-ray diffraction, and experimental electronic circular dichroism (ECD) measurements. Spiroterreusnoids A-F represent the first examples of adducts composed of 3,5-dimethylorsellinic acid-based meroterpenoids. It is noteworthy that spiroterreusnoids A-F possessing a spiro-dioxolane moiety exhibited potential abilities in inhibiting BACE1 (IC50 values ranging from 5.86 to 27.16 μM) and AchE (IC50 values ranging from 22.18 to 32.51 μM), while the other analogues without this fragment displayed no such activities. Taken together, spiroterreusnoids A-F represent the first multitargeted natural adducts that could inhibit BACE1 and AchE, and might provide a new template for the development of new anti-Alzheimer's disease drugs.

Abstract
An HPLC-DAD-directed chemical investigation of the soil-derived fungus Aspergillus versicolor QC812 resulted in the isolation and identification of eight new linearly fused prenylated indole alkaloids, asperversiamides I-P (1-8), along with a congener, asperversiamide H (9). Their structures and absolute configurations were determined by spectroscopic analysis including HRESIMS and 1D and 2D NMR, electronic circular dichroism analysis, and single-crystal X-ray diffraction. Asperversiamide I (1), the first diketopiperazine derived from d-proline and l-tryptophan, possesses an unprecedented C-11-spiro-fused 6/6/5/5/6/5 hexacyclic ring system. Asperversiamide J (2) is the first linearly fused 6/6/5 tricyclic prenylated indole alkaloid to be reported. 1 and 2 showed moderate inhibitory activities against HeLa cells with IC50 values of 7.3 and 6.4 μM, respectively.

Abstract
Eleven highly oxygenated meroterpenoids, named terreustoxins A-K, along with five known analogues, were isolated from the Antarctic fungus Aspergillus terreus. The structures and absolute configurations of these undescribed compounds were characterized by NMR spectroscopy, single-crystal X-ray crystallography, and ECD experiments. Terreustoxins A-D are the first examples of meroterpenoids with two ortho-hydroxy groups at C-6 and C-7 in the terretonins family. Terreustoxin C and terretonin inhibited the proliferation of Con A-induced murine T cells at the concentration of 10 μM.
