[PMID: 37642432 DOI: 10.1080/10286020.2023.2251114] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 08/17/2023] [Accepted: 08/17/2023] [Indexed: 08/31/2023]
Abstract
Two new compounds named 3(S)-hydroxy-1-(2,4,5-trihydroxy-3,6- dimethylphenyl)-hex-4E-en-1-one (1) and acremonilactone (2), together with nine known compounds (3-11), were isolated from the fermentation broth of Acremonium sp. associated with marine sediments collected from South China Sea. NMR and HRESIMS spectroscopic analysis elucidated the structure of two new compounds. Compound 2 had characteristic rotary gate shape skeleton with a six-membered lactone. Compounds 1 and 9 showed DPPH radical scavenging activity with inhibition rates of 96.50 and 85.95% at the concentration of 0.5 mg/ml, respectively. Moreover, compounds 4, 6 and 11 showed definite antibacterial activity against Staphylococcus aureus ATCC 6538.

Diverse indole-diterpenoids with protein tyrosine phosphatase 1B inhibitory activities from the marine coral-derived fungus Aspergillus sp. ZF-104. PHYTOCHEMISTRY 2023; 216:113888. [PMID: 37839588 DOI: 10.1016/j.phytochem.2023.113888] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 10/05/2023] [Accepted: 10/05/2023] [Indexed: 10/17/2023]
Abstract
Eight previously undescribed indole-diterpenoids named penerpenes O-V (1-8), together with seven known analogues (9-14), were isolated from the marine soft coral-derived fungus Aspergillus sp. ZF-104. Their structures including the absolute configurations of these compounds were assigned on the basis of spectroscopic data and ECD analysis along with quantum ECD and NMR calculations. Compounds 4 and 5 bear rare indolin-2-one units in their structures and 6 bears a reconstructed novel skeleton in which the indole ring and the terpenoid substructure are cleaved before they are reconnected through the nitrogen atom. Compounds 1, 2, 7, and 10 showed protein tyrosine phosphatase 1B (PTP1B) inhibitory activities comparable to that of the positive control NaVO3.

Meroterpenoids and Steroids from the Marine-Derived Fungus Trametes sp. ZYX-Z-16. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27248782. [PMID: 36557915 PMCID: PMC9784055 DOI: 10.3390/molecules27248782] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 12/01/2022] [Accepted: 12/09/2022] [Indexed: 12/14/2022]
Abstract
Marine fungi can metabolize structurally diverse active components, and have become an important source of drug lead molecules. In the present study, the chemical investigation on the EtOAc extract of the fermentation broth of the marine-derived fungus Trametes sp. ZYX-Z-16 led to the isolation of eight meroterpenoids (1-8), including two undescribed ones, together with ten ergostane steroid analogues (9-18). The structures of two new spiromeroterpenoids, asnovolin H (1) and asnovolin I (2), were determined based on 1D, 2D NMR, and HRESIMS spectroscopic data along with ECD spectra calculations. All compounds were tested for antibacterial and α-glucosidase inhibitory activity. Among them, compound 12 showed definite antibacterial activities against Staphylococcus aureus ATCC 6538 (MIC 32 μg/mL) and Bacillus subtilis ATCC 6633 (MIC 16 μg/mL). In addition, compounds 9 and 10 showed superior inhibitory activity, with IC50 values of 104.1 and 111.3 μM, respectively, to the positive control acarbose (304.6 μM).

Abstract
Five new perylenequinone derivatives, altertoxins VIII–XII (1–5), as well as one known compound cladosporol I (6), were isolated from the fermentation broth of the marine-derived fungus Cladosporium sp. KFD33 from a blood cockle from Haikou Bay, China. Their structures were determined based on spectroscopic methods and ECD spectra analysis along with quantum ECD calculations. Compounds 1–6 exhibited quorum sensing inhibitory activities against Chromobacterium violaceum CV026 with MIC values of 30, 30, 20, 30, 20 and 30 μg/well, respectively.
