Rapid Discovery of Substances with Anticancer Potential from Marine Fungi Based on a One Strain-Many Compounds Strategy and UPLC-QTOF-MS. Mar Drugs 2023; 21:646. [PMID: 38132967 PMCID: PMC10745104 DOI: 10.3390/md21120646] [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: 10/24/2023] [Revised: 12/12/2023] [Accepted: 12/13/2023] [Indexed: 12/23/2023] Open
Abstract
The secondary metabolites of marine fungi with rich chemical diversity and biological activity are an important and exciting target for natural product research. This study aimed to investigate the fungal community in Quanzhou Bay, Fujian, and identified 28 strains of marine fungi. A total of 28 strains of marine fungi were screened for small-scale fermentation by the OSMAC (One Strain-Many Compounds) strategy, and 77 EtOAc crude extracts were obtained and assayed for cancer cell inhibition rate. A total of six strains of marine fungi (P-WZ-2, P-WZ-3-2, P-WZ-4, P-WZ-5, P56, and P341) with significant changes in cancer cell inhibition induced by the OSMAC strategy were analysed by UPLC-QTOF-MS. The ACD/MS Structure ID Suite software was used to predict the possible structures with inhibitory effects on cancer cells. A total of 23 compounds were identified, of which 10 compounds have been reported to have potential anticancer activity or cytotoxicity. In this study, the OSMAC strategy was combined with an untargeted metabolomics approach based on UPLC-QTOF-MS to efficiently analyse the effect of changes in culture conditions on anticancer potentials and to rapidly find active substances that inhibit cancer cell growth.

Abstract
Marine microorganisms have proven to be a source of new natural products with a wide spectrum of biological activities relevant in different industrial sectors. The ever-increasing number of sequenced microbial genomes has highlighted a discrepancy between the number of gene clusters potentially encoding the production of natural products and the actual number of chemically characterized metabolites for a given microorganism. Homologous and heterologous expression of these biosynthetic genes, which are often silent under experimental laboratory culture conditions, may lead to the discovery of new cryptic natural products of medical and biotechnological interest. Several new genetic and cultivation-based strategies have been developed to meet this challenge. The OSMAC approach (one strain-many compounds), based on modification of growth conditions, has proven to be a powerful strategy for the discovery of new cryptic natural products. As a direct extension of this approach, the addition of chemical elicitors or epigenetic modifiers have also been used to activate silent genes. This review looks at the structures and biological activities of new cryptic metabolites from marine-derived microorganisms obtained using the OSMAC approach, the addition of chemical elicitors, and enzymatic inhibitors and epigenetic modifiers. It covers works published up to June 2021.

[PMID: 34426151 DOI: 10.1016/j.bioorg.2021.105269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/14/2021] [Accepted: 08/12/2021] [Indexed: 10/20/2022]
Abstract
By tracing the 13C NMR resonances for carbonyls and enols, four new oxidized phomaligol derivatives, phomaligols F-I (1-4), along with seven known compounds (5-11) were isolated from the culture of the fungus Aspergillus flavus BB1 isolated from the marine shellfish Meretrix meretrix collected on Hailing Island, Yangjiang, China. The chemical structures and the absolute configurations of the new compounds were elucidated by MS, NMR, ECD, optical rotation, and 13C NMR calculations. Compounds 1 and 2 represent the first examples of phomaligol derivatives that contain an unusual bicyclic skeleton. All isolated compounds were tested for their cytotoxic activity. Among them, sporogen-AO 1 (8) showed potent inhibitory activity against the cancer cell lines A549, H1299, SK-BR-3, and HCT116 with IC50 values of 0.13, 0.78, 1.19, and 1.32 μM, respectively. Phomaligol G (2) displayed cytotoxic activity against the A549 and H1299 cell lines with IC50 values of 46.86 and 51.87 μM respectively. Additionally, phomaligol H (3) demonstrated cytotoxic activity against the A549 cell line with an IC50 value of 65.53 μM. Mechanistic studies of compound 8 showed that it induced apoptosis of HCT116 cells in a dose-dependent manner.

Abstract
Asperspiropene A was originally reported to have a unique 1,8-dioxaspiro[4.5]decane skeleton. During the course of our ongoing research for novel marine natural products, we isolated compound 1, which has identical 1D and 2D NMR data to asperspiropene A. Detailed and careful analysis of spectroscopic data led us to revise the structure of asperspiropene A and to determine its absolute configuration.

Induction of metabolic variability of the endophytic fungus Xylaria sp. by OSMAC approach and experimental design. Arch Microbiol 2021; 203:3025-3032. [PMID: 33779769 DOI: 10.1007/s00203-021-02283-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 03/13/2021] [Accepted: 03/16/2021] [Indexed: 10/21/2022]
Abstract
This work has as the main focus, to analyze the behavior of physic-chemical variations from the fungus Xylaria sp., through the OSMAC (One Strain, Many Compounds) approach as an efficient way of obtaining new compounds. To perform such inductions and to explore the variability of the metabolic network of this microorganism, a factorial design was designed to induce variability (or enhancement) of metabolites. In view of chemometric insights, the planned inductions were imposed on the microorganism and variations in the chemical profile were observed in the crude extracts. Through mass spectrometry (HR-ESI-MS) and nuclear magnetic resonance-based profiles, combined with multivariate analysis through Principal Component Analysis (PCA), it was observed a marked variability of signals, confirming the efficacy in the metabolic alteration, defining the culture medium and agitation as the most important variables in the metabolic variability of the fungus. However, the extract mass is more significant for the agitation variable, and there is no relationship between the mass of crude extract and the amount of molecular signals of the complex matrices studied.
