Abstract
Talaromeroterpenoids A-G (1-7), seven new 3,5-dimethylorsellinic-acid-derived meroterpenoids, and two known analogues (8 and 9) were isolated from the mangrove endophytic fungus Talaromyces sp. JNQQJ-4 by genome analysis and a molecular networking strategy. Their structures and absolute configurations were established by nuclear magnetic resonance data, high-resolution electrospray ionization mass spectrometry, and X-ray diffraction. Compound 1 possesses an unprecedented rearrangement 7/6/6/6/5/5 hexacyclic skeleton based on a 2,8,18,21-tetraoxa-hexacyclo-[12.5.2.13,12.01,16.04,10.016,22]docosane core. In bioassays, compound 2 exhibited promising anti-inflammatory activity by suppressing the expression of pro-inflammatory factors and inactivating the NF-κB signaling pathway.
期刊介绍：
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
