Abstract
A new benzoquinone, guxiumasperone A (1), and a new diisoprenyl-cyclohexene-type meroterpenoids, biscognienyne M (2), along with four known diisoprenyl-cyclohexene analogues was isolated from the mangrove endophytic fungus Aspergillus QG1a. Their structures were determined by extensive spectral analysis of 1D and 2D NMR, HR-ESI- MS, and X-ray crystallography. Compound 1 was deduced by a single-crystal X-ray diffraction analysis, and the absolute configuration of 2 was further unequivocally elucidated by comparing the experimental electronic circular dichroism (ECD) data with calculated ECD spectra. Compounds 1 and 2 showed significant cytotoxic activity against selected tumour cells. Particularly, compound 2 exhibited strong activity against A2780 cancer cells with an IC50 value of 6.8 μM.

Fitoterapia 2023; 171:105693. [PMID: 37769999 DOI: 10.1016/j.fitote.2023.105693] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 09/12/2023] [Accepted: 09/23/2023] [Indexed: 10/02/2023]
Abstract
An investigation on bioactive metabolites from the mangrove endophytic fungus Aspergillus sp. GXNU-4QQY1a led to the isolation of two undescribed cyclic peptides, guaspertide A (1) and guaspertide B (2), together with six known compounds, 3-8. These structures and the new compounds' absolute configuration were determined by mass spectrometry analysis, nuclear magnetic resonance spectrum, electronic circular dichroism, and single-crystal X-ray diffraction. Insecticidal assays were carried out with compounds 1-8, and the results showed that compounds 1-3 and 8 exhibited good insecticidal activity against citrus psyllids.

Abstract
A new chromone derivative, aspergione A (1), along with seven known metabolites, was isolated from a mangrove endophytic fungus, Aspergillus sp. GXNU-B1, which was collected from mangrove Acanthus ilicifolius L. Their structures and the absolute configuration of 1 were elucidated based on the analysis of HR-ESI-MS, NMR, and ECD calculation. Compounds 1-8 were evaluated for their anti-inflammatory effects on the production of nitricoxide (NO). Compounds 1 and 8 have potent inhibitory effects against NO production in activated macrophages with IC50 values of 38.26 and 44.30 μM, respectively.
