[PMID: 39242361 DOI: 10.1002/cbdv.202401938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2024] [Revised: 09/03/2024] [Accepted: 09/06/2024] [Indexed: 09/09/2024]
Abstract
A dimeric citrinin derivative with a unique spiro[chroman-2,3'-isochroman] skeleton, xerucitrinic acid C (1), and a new citrinin derivative, cladosporin E (6), along with ten known polyketides (2-5 and 7-12), were isolated from the mangrove sediment-derived fungus Talaromyces sp. SCSIO 41428. Their structures were elucidated through comprehensive spectral data analysis. The absolute configurations of 1 and 6 were determined by quantum chemical calculations. Compound 1 exhibited significant inhibitory effects on Staphylococcus aureus and Streptococcus suis, with the MIC of 25 μg/mL for both bacterial strains. Xerucitrinin C (3) exhibited significant radical scavenging activity against DPPH, with an IC50 value of 25.4 μM, and also demonstrated inhibitory activity against phosphodiesterase-4 (PDE4). Moreover, cladosporin C (7) notably inhibited prostate cancer cells PC-3 and 22Rv1, with IC50 values of 6.10 and 9.25 μM, respectively.

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.
