- Eremophilane- and Acorane-Type Sesquiterpenes from the Deep-Sea Cold-Seep-Derived Fungus CS-280 Cultured in the Presence of Autoclaved QDIO-4. Chen, Xiao-Dan Li, Xin Li, Xiao-Ming Yang, Sui-Qun Wang, Bin-Gui Pseudomonas aeruginosa Sesquiterpenes Humans Anti-Inflammatory Agents Crystallography, X-Ray Polycyclic Sesquiterpenes Cyclooxygenase 2 Molecular Docking Simulation Cyclooxygenase 2 Inhibitors Six new sesquiterpenes, including four eremophilane derivatives fureremophilanes A-D (-) and two acorane analogues furacoranes A and B ( and ), were characterized from the culture extract of the cold-seep derived fungus CS-280 co-cultured with autoclaved QDIO-4. All the six compounds were highly oxygenated especially and with infrequent epoxyethane and tetrahydrofuran ring systems. The structures of - were established on the basis of detailed interpretation of 1D and 2D NMR and MS data. Their relative and absolute configurations were assigned by a combination of NOESY and single crystal X-ray crystallographic analysis, and by time-dependent density functional (TDDFT) ECD calculations as well. All compounds were tested the anti-inflammatory activity against human COX-2 protein, among which, compounds and displayed activities with IC values 123.00 µM and 93.45 µM, respectively. The interaction mechanism was interpreted by molecular docking.
