Tu L, Shen S, Chen X, Ding W, Wang Y, Chen X, Guo Y, Huang K, Sun Y, Song X, Luo M. Natural Brominated Fatty Acid-containing Flavonoids Bromaliphflas A-B From Marine-derived Streptomyces qinglanensis 1678. Chem Biodivers 2025:e202500401. [PMID: 40208245 DOI: 10.1002/cbdv.202500401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2025] [Revised: 04/09/2025] [Accepted: 04/10/2025] [Indexed: 04/11/2025]
Abstract
Two new brominated fatty acid-containing flavonoids (1 and 2), together with the known compound 5-hydroxy-3',4',7-trimethoxyflavone (HTMF) (3), were obtained from marine-derived Streptomyces qinglanensis 1678. The structures of the new isolates were established on the basis of their electrospray ionization high-resolution mass spectrometry, one-, and two-dimensional nuclear magnetic resonance datasets. Bioactivity results show that compounds 2 and 3 exhibited moderate anti-inflammatory bioactivities. It seems that HTMF substitution could enhance the bioactivities of the anti-inflammatory bioactivities of 8-bromohexanoic acid, however, the influence of 6/8-bromohexanoic acid on the anti-inflammatory bioactivities of HTMF may depend on the length of the fatty chain.

Phytochemical Constituents of Aquilaria malaccensis Leaf Extract and Their Anti-Inflammatory Activity against LPS/IFN-γ-Stimulated RAW 264.7 Cell Line. ACS OMEGA 2022; 7:15637-15646. [PMID: 35571776 PMCID: PMC9096934 DOI: 10.1021/acsomega.2c00439] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 04/13/2022] [Indexed: 06/15/2023]
Abstract
This study aims to identify the major phytochemical constituents in Aquilaria malaccensis (Thymelaeaceae) ethanolic leaf extract (ALEX-M) and elucidate their ability to suppress nitric oxide (NO) production from a murine macrophage-like cell line (RAW 264.7) stimulated by lipopolysaccharide (LPS) and interferon-γ (IFN-γ). Dichloromethane (DCM) and ethyl acetate (EtOAc) fractions of ALEX-M were subjected to column chromatography. Eight known compounds were isolated for the first time from this species. Compounds were identified using spectroscopic techniques (IR, UV, HRESIMS, and 1D and 2D NMR). Anti-inflammatory activity of both extract and isolated compounds were investigated in vitro. The fractions offered the isolation of epifriedelanol (1), 5-hydroxy-7,4'-dimethoxyflavone (2), luteolin-7,3',4'-trimethyl ether (3), luteolin-7,4'-dimethyl ether (4), acacetin (5), aquilarinenside E (6), iriflophenone-2-O-α-l-rhamnopyranoside (7), and iriflophenone-3-C-β-glucoside (8). The findings suggest the pharmacological potential of the crude extract (ALEX-M) and its isolates as natural anti-inflammatory agents, capable of suppressing NO production in RAW 264.7 cells stimulated by LPS/IFN-γ.
