NATURAL PRODUCTS AND BIOPROSPECTING 2025; 15:19. [PMID: 40097883 PMCID: PMC11914449 DOI: 10.1007/s13659-025-00501-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2024] [Accepted: 02/23/2025] [Indexed: 03/19/2025]
Abstract
The rapid emergence of drug-resistant microbial pathogens has posed challenges to global health in the twenty-first century. This development has significantly made most antibiotics ineffective in the treatment of infections they cause, resulting in increasing treatment costs and annual death rates. To address the challenge posed by these pathogens, we explore the potential of secondary metabolites from Aspergillus species as a source of new and effective therapeutic agents to treat drug-resistant infections. Terpenoids, a distinct group of natural products, are extensively distributed in plants and fungi, and have been attributed with significant antibacterial, anticancer, and antiviral activities. In this review, we present an overview of Aspergillus species, and review the novel terpenoids isolated from them from 2019 to April 2024, highlighting anti-infective activity against members of the ESKAPE pathogens. We further focus on the strategies through which the structural framework of these new terpenoids could be modified and/or optimized to feed a pipeline of new lead compounds targeting microbial pathogens. Overall, this review provides insight into the therapeutic applications of terpenoids sourced from Aspergillus species and the potential for the discovery of new compounds from these fungi to combat antimicrobial resistance.

[PMID: 39330305 PMCID: PMC11433063 DOI: 10.3390/md22090424] [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: 08/14/2024] [Revised: 09/14/2024] [Accepted: 09/16/2024] [Indexed: 09/28/2024] Open
Abstract
Marine microbial secondary metabolites with diversified structures have been found as promising sources of anti-inflammatory lead compounds. This review summarizes the sources, chemical structures, and pharmacological properties of anti-inflammatory natural products reported from marine microorganisms in the past three years (2021-2023). Approximately 252 anti-inflammatory compounds, including 129 new ones, were predominantly obtained from marine fungi and they are structurally divided into polyketides (51.2%), terpenoids (21.0%), alkaloids (18.7%), amides or peptides (4.8%), and steroids (4.3%). This review will shed light on the development of marine microbial secondary metabolites as potential anti-inflammatory lead compounds with promising clinical applications in human health.

Abstract
Covering: January to the end of December 2022This review covers the literature published in 2022 for marine natural products (MNPs), with 645 citations (633 for the period January to December 2022) referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, the submerged parts of mangroves and other intertidal plants. The emphasis is on new compounds (1417 in 384 papers for 2022), together with the relevant biological activities, source organisms and country of origin. Pertinent reviews, biosynthetic studies, first syntheses, and syntheses that led to the revision of structures or stereochemistries, have been included. An analysis of NP structure class diversity in relation to biota source and biome is discussed.

Abstract
Marine fungi, such as species from the Penicillium and Aspergillus genera, are prolific producers of a diversity of natural products with cytotoxic properties. These fungi have been successfully isolated and identified from various marine sources, including sponges, coral, algae, mangroves, sediment, and seawater. The cytotoxic compounds derived from marine fungi can be categorized into five distinct classes: polyketides, peptides, terpenoids and sterols, hybrids, and other miscellaneous compounds. Notably, the pre-eminent group among these compounds comprises polyketides, accounting for 307 out of 642 identified compounds. Particularly, within this collection, 23 out of the 642 compounds exhibit remarkable cytotoxic potency, with IC50 values measured at the nanomolar (nM) or nanogram per milliliter (ng/mL) levels. This review elucidates the originating fungal strains, the sources of isolation, chemical structures, and the noteworthy antitumor activity of the 642 novel natural products isolated from marine fungi. The scope of this review encompasses the period from 1991 to 2023.
