Wijerathna, Parakkrama Chen, Xinqi Chen, Yi Zhang, Yufan Cai, Jian Cong, Mengjing Liu, Ying Jayasinghe, Lalith Liu, Yonghong Ratnasekera, Disna Zhou, Xuefeng Talaromyces Sri Lanka Molecular Docking Simulation Neuraminidase Lactones Crystallography, X-Ray Magnetic Resonance Spectroscopy Molecular Structure Enzyme Inhibitors Three previously uncharacterized lactones, namely penicianstinoid L (), talaromyketide J () and peniciisocoumarin K (), along with twenty-eight known compounds (-), were yielded from the mangrove-derived fungus sp. SCSIO41445, collected from Mangrove Park (NARA), Sri Lanka. Their structures were established by HRESIMS and NMR spectroscopic analysis (including H and C NMR, HSQC, and HMBC), with the stereostructures of and being confirmed by single-crystal X-ray crystallographic analysis. Furthermore, compounds - were evaluated in terms of their neuraminidase (NA) inhibitory activities. These bioassay results revealed that three lactones (, , and ) of them exerted NA inhibitory effects, with IC values of 46.66 ± 2.31, 20.78 ± 1.89, and 34.14 ± 2.56 µM, respectively. Moreover, molecular docking analysis demonstrated the potential of these compounds to inhibit NA enzymes, revealing specific interactions between the compounds and target proteins. |
