Fitoterapia 2023; 171:105710. [PMID: 37866423 DOI: 10.1016/j.fitote.2023.105710] [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: 08/20/2023] [Revised: 10/15/2023] [Accepted: 10/19/2023] [Indexed: 10/24/2023]
Abstract
Six new sesquiterpenes, fusarchlamols A-F (1, 2, 4-7); one new natural product of sesquiterpenoid, methyltricinonoate (3); and ten known compounds were found from Fusarium sp. cultured in two different media by the one strain many compounds strategy. The compounds (1, 2, and 4-11) were isolated from Fusarium sp. in PDB medium, and compounds (3-5, 8, and 10-17) were discovered from Fusarium sp. in coffee medium. Additionally, the configuration of 8 was first reported in the research by Mosher's method. The structures were established by 1D, 2D NMR, mass spectrometry, calculated ECD spectra, and Mosher's method. Compounds 1, 2, 6/7, 12, and 16 indicated significant antifungal activities against the phytopathogen Alternaria alternata isolated from Coffea arabica with MICs of 1 μg/mL. The investigation on the anti-phytopathogen activity of metabolites can provide lead compounds for agrochemicals.

Abstract
Facile construction of 1,3-dienes building upon cross-electrophile coupling of two open-chain vinyl halides is disclosed in this work, showing moderate chemoselectivities between the terminal bromoalkenes and internal vinyl bromides. The present method is mild and tolerates a range of functional groups and can be applied to the total synthesis of a tobacco fragrance solanone.

Abstract
A genetic dereplication approach in combination with differential gene expression led to the discovery of three new sesquiterpenes, tricinoloniol acids (TRAs) A-C (1-3) and the known fusidilactone A (4) from T. hypoxylon. Comparative transcriptomic analysis and targeted deletion identified the biosynthetic route for TRAs. Our results demonstrate an alternative application of the genetic dereplication method for exploring the biosynthesis of cryptic secondary metabolites (SMs), which utilizes the coordinated expression of trichothecene (tri) and tra cluster genes.
