Luteolin 7-O-glucuronide (Luteolin-7-O-glucuronide) is a flavonoid glycoside found in plants, exhibiting antimicrobial, antioxidant, antimutagenic, antigenotoxic, anti-inflammatory, and anti-arthritic activities. As an effective free radical scavenger, it inhibits the activity of matrix metalloproteinases (MMPs), with IC50 values of 17.63, 7.99, 11.42, 12.85, and 0.03 μM for MMP-1, MMP-3, MMP-8, MMP-9, and MMP-13, respectively.

Synonyms: Luteolin 7-glucuronide; Luteolin-7-O-β-D-glucuronide

Isoform Comparison

Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
Phaeocystis globosa 20, 40, 60, 80, 100 μg/mL 96 hours To evaluate the inhibitory effect of luteolin-7-O-glucuronide on the growth of Phaeocystis globosa. The results showed that luteolin-7-O-glucuronide significantly inhibited the growth of Phaeocystis globosa, with the inhibition rate increasing with concentration. Int J Environ Res Public Health. 2019 Jul 23;16(14):2615
rat primary cortical neurons 3.7–100 µM 16 hours LGU effectively improved the OGD-induced decrease in neuronal viability and increase in neuronal death, inhibited intracellular Ca2+ overload, ATP depletion, and mitochondrial membrane potential decrease. Molecules. 2024 Apr 7;29(7):1665
MH-S cells 5 mM, 10 µM, 25 µM 15 hours To investigate the inhibitory effect of L7Gn on NLRP3 inflammasome activation in LPS-induced MH-S cells. Results showed that L7Gn significantly suppressed the protein levels of NLRP3, ASC, and caspase-1, and reduced the mRNA and protein levels of IL-1β and IL-18. Pharmaceuticals (Basel). 2024 Dec 21;17(12):1731
RAW 264.7 macrophages 5–50 µM 2 h pre-treatment followed by LPS stimulation for 24 h To evaluate the anti-inflammatory and anti-oxidative effects of L7Gn. L7Gn suppressed the expression of inflammatory mediators (e.g., iNOS, COX-2, IL-6, IL-1β, and TNF-α) by inhibiting TAK1 phosphorylation, leading to reduced activation of NF-κB, p38, and JNK. Additionally, L7Gn enhanced the expression of anti-oxidative regulators (e.g., HO-1, GCLC, and NQO1) via Nrf2 activation. Int J Mol Sci. 2020 Mar 16;21(6):2007

In Vivo:

Species
Animal Model
Administration Dosage Frequency Description References
Wistar rats LPS-induced acute lung injury (ALI) model Aerosol inhalation 20.8 mg/kg and 41.6 mg/kg Once daily for three days To evaluate the protective effect of L7Gn on LPS-induced ALI in rats. Results showed that L7Gn significantly improved lung function, reduced lung tissue damage and inflammatory cell infiltration, and inhibited NLRP3 inflammasome activation. Pharmaceuticals (Basel). 2024 Dec 21;17(12):1731
C57BL/6 male mice Sleep deprivation stress model Oral 0.3, 1, and 3 mg/kg Once daily for 5 days L7Gn treatment improved depression-like and stress coping behaviors induced by SD stress, as confirmed by the tail suspension test and forced swimming test, via activation of the BDNF signaling pathway. Nutrients. 2022 Aug 12;14(16):3314
Adult male Sprague-Dawley rats Middle cerebral artery occlusion (MCAO) model Tail vein injection 0.24, 0.72, and 2.16 mg/kg Single dose at 0.5 h after MCAO, evaluated at 24 h LGU significantly improved neurological deficit scores, infarction volume rate, and brain water content rate in MCAO rats. Molecules. 2024 Apr 7;29(7):1665
