Fitoterapia 2024; 178:106152. [PMID: 39084567 DOI: 10.1016/j.fitote.2024.106152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 07/27/2024] [Accepted: 07/28/2024] [Indexed: 08/02/2024]
Abstract
Six previously undescribed 2, 9-deoxyflavonoids (1/2a, 1/2b, 6, and 7), along with six known compounds (3-5, and 8-10), were isolated from the twigs and leaves of Aglaia odorata. Their structures were determined by a combination of spectral analysis, ECD calculation and enzymatic hydrolysis assay. Surprisingly, (±) aglaindanone E (11a, 11b) were unexpectedly formed as the derivatives of compounds 3-6 when exposed to ambient natural light. Furthermore, the plausible biosynthetic pathway of 2, 9-deoxyflavonoids was proposed and chemically mimicked. In biological activity assay, compounds 1/2a, 1/2b, 4, and 6 showed potential protective effects in the 0.75%CSE-induced BEAS-2B cells injury model.

JOURNAL OF ASIAN NATURAL PRODUCTS RESEARCH 2024:1-8. [PMID: 38234138 DOI: 10.1080/10286020.2024.2301998] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 12/29/2023] [Indexed: 01/19/2024]
Abstract
An anti-neuroinflammatory activities-guided phytochemical research of Wikstroemia lungtzeensis was performed for the first time. Three undescribed carotane-type sesquiterpenes, excoecafolinols C-E (1-3), and nine known sesquiterpene derivatives were isolated from the effective ethyl acetate extract of W. lungtzeensis. Their structures were determined based on multiple spectroscopic techniques and electronic circular dichroism (ECD) spectra. Furthermore, the anti-neuroinflammatory activities of the identified compounds were evaluated in lipopolysaccharide-stimulated BV-2 cells. Among them, six components (1, 2, 4, 7, 11, 12) exhibited significant inhibitory effects on nitric oxide (NO) production, with IC50 values ranging from 10.48 to 49.41 μM (positive control minocycline, IC50 53.20 μM). Carotane-type sesquiterpenes (1, 2, 4) with high content and significant inhibitory effects, are considered to be major active ingredients of W. lungtzeensis, which might serve as potential therapeutic agents for neurodegenerative diseases.
