Antiviral activity of sulphated specialized metabolites from sea urchin Clypeaster humilis: in vitro and in silico studies. RSC Adv 2024; 14:14185-14193. [PMID: 38690113 PMCID: PMC11058476 DOI: 10.1039/d4ra01966k] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/05/2024] [Indexed: 05/02/2024] Open
Abstract
Chemical investigations of the sea urchin Clypeaster humilis has led to separation of twelve compounds including one new sulfonic acid derivative (7R) tridec-1-en-7-yl hydrogen sulphate (1), first isolated from natural source, pyridine-3-yl methane sulfonate (2), and first isolated from marine organisms, boldine (12), in addition to nine known compounds (3-11), which were isolated for the first time from the genus Clypeaster. Their structures were elucidated based on spectroscopic analyses (1D and 2D NMR), HR-ESI-MS as well as comparison with the previously reported data. The antiviral activity of the crude extract and sulphated compounds were evaluated using MTT colorimetric assay against Coxsackie B4 virus. The crude extract and compound 1 showed very potent antiviral activity with a percentage of inhibition equal to 89.7 ± 0.53% and 86.1 ± 0.92%, respectively. Results of the molecular docking analysis of the isolated compounds within Coxsackie Virus B4 (COX-B4) X-ray crystal structure and quantum chemical calculation for three sulphated compounds are in a consistent adaptation with the in vitro antiviral results. The pharmacokinetic properties (ADME) of isolated compounds were determined.

Abstract
A novel alkaloid with a hexa-tetra-hexa-cyclic skeleton, Bi-4-methoxycarbonyl-2-quinolone (1), was discovered during the investigation of Brucea javanica. Additionally, six known alkaloids (2-7) were also found. The chemical structures of these compounds were identified using HRESIMS and 1D and 2D NMR spectroscopic analysis. Additionally, the absolute configuration of the new compound 1 was determined through X-ray single crystal diffraction. Compound 1 exhibited significant anti-inflammatory activity in RAW264.7 cells and demonstrated promising anti-cancer effects in Lewis cells.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27113573. [PMID: 35684510 PMCID: PMC9182397 DOI: 10.3390/molecules27113573] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 05/29/2022] [Accepted: 05/31/2022] [Indexed: 11/16/2022]
Abstract
A new flavonoid, saffloflavanside (1), a new sesquiterpene, safflomegastigside (2), and a new amide, saffloamide (3), together with twenty-two known compounds (4-25), were isolated from the flowers of Carthamus tinctorius L. Their structures were determined based on interpretation of their spectroscopic data and comparison with those reported in the literature. The protective effects against lipopolysaccharide (LPS)-stimulated damage on human normal lung epithelial (BEAS-2B) cells of the compounds were evaluated using MTT assay and cellular immunofluorescence assay. The results showed that compounds 2-3, 8-11, and 15-19 exhibited protective effects against LPS-induced damage to BEAS-2B cells. Moreover, compounds 2-3, 8-11, and 15-19 can significantly downregulate the level of nuclear translocation of NF-κB p-p65. In summary, this study revealed chemical constituents with lung protective activity from C. tinctorius, which may be developed as a drug for the treatment of lung injury.
