Antioxidant and Anti-Inflammatory Activities of Flavanones from Glycyrrhiza glabra L. (licorice) Leaf Phytocomplexes: Identification of Licoflavanone as a Modulator of NF-kB/MAPK Pathway.[Pubmed: 31226797]

Antioxidants (Basel). 2019 Jun 20;8(6). pii: E186.

Inflammation represents an adaptive response generated by injuries or harmful stimuli. Natural remedies represent an interesting alternative to traditional therapies, involving several biochemical pathways. Besides, the valorization of agrochemical wastes nowadays seems to be a feasible way to reduce the health spending and improve the accessibility at bioactive natural compounds.
METHODS AND RESULTS:
In this context, the chemical composition of three Glycyrrhiza glabra L. (licorice) leaf extracts, obtained through maceration or ultrasound-assisted method (fresh and dried leaves) was investigated. A guided fractionation obtained three main components: pinocembrin, glabranin and Licoflavanone. All the extracts showed similar antioxidant properties, evaluated by 2,2'-diphenyl-1-picrylhydrazyl (DPPH) or 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) Diammonium Salt (ABTS) assay, while, among the isolated compounds, Licoflavanone exhibited the best antioxidant activity. The anti-inflammatory activity of the extracts and the purified compounds was investigated in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophages. Extract C and Licoflavanone showed a good anti-inflammatory activity without affecting cell viability, as they decreased nitrite levels even when used at 12.5 μg/mL (p < 0.005) and 50 μM concentration (p < 0.001), respectively.
CONCLUSIONS:
Interestingly, Licoflavanone markedly decreased pro-inflammatory cytokines and cyclooxygenase 2/inducible nitric oxide synthase (COX-2/iNOS) expression levels (p < 0.001). A modulation of nuclear factor kappa B/mitogen-activated protein kinases (NF-kB/MAPK) pathway underlay such behavior, highlighting the potential of this natural compound as a new scaffold in anti-inflammatory drug research.

Flavonoid variation in the leaves of Glycyrrhiza glabra.[Reference: WebLink]


METHODS AND RESULTS:
Genistein, pinocembrin, prunetin, 6-prenylnaringenin, Licoflavanone and wighteone were isolated from the leaves of Glycyrrhiza glabra collected on the west coast of Anatolia, whereas lupiwighteone was found only in the leaves of G. glabra growing in middle or east Anatolia.
CONCLUSIONS:
The G. glabra plants growing in different areas of Turkey could be classified into two types according to the occurrence of lupiwighteone in the leaf.

The anticancer potential of flavonoids isolated from the stem bark of Erythrina suberosa through induction of apoptosis and inhibition of STAT signaling pathway in human leukemia HL-60 cells.[Pubmed:23850732]

Chem Biol Interact. 2013 Sep 25;205(2):128-37.

Erythrina suberosa is an ornamental tall tree found in India, Pakistan, Nepal, Bhutan, Burma, Thailand and Vietnam. We have isolated four known distinct metabolites designated as alpha-Hydroxyerysotrine, 4'-Methoxy Licoflavanone (MLF), Alpinumisoflavone (AIF) and Wighteone. Among the four isolated metabolites the two flavonoids, MLF and AIF were found to be the most potent cytotoxic agent with IC50 of approximately 20muM in human leukemia HL-60 cells. We are reporting first time the anticancer and apoptotic potential of MLF and AIF in HL-60 cells. Both MLF and AIF inhibited HL-60 cell proliferation and induce apoptosis as measured by several biological endpoints. MLF and AIF induce apoptosis bodies formation, enhanced annexinV-FITC binding of the cells, increased sub-G0 cell fraction, loss of mitochondrial membrane potential (Deltapsim), release of cytochrome c, Bax, activation of caspase-9, caspase-3 and PARP (poly ADP Ribose polymers) cleavage in HL-60 cells. MLF and AIF also increase the expression of apical death receptor, Fas, with inhibition of anti-apoptotic protein Bid. All the above parameters revealed that these two flavonoids induce apoptosis through both extrinsic and intrinsic apoptotic pathways in HL-60 cells. In spite of apoptosis, these two flavonoids significantly inhibit nuclear transcription factor NF-kappaB and STAT (Signal Transducer and Activator of Transcription) signaling pathway, which are highly expressed in leukemia. The present study provide an insight of molecular mechanism of cell death induced by MLF and AIF in HL-60 cells which may be useful in managing and treating leukemia.

Phenolics from Glycyrrhiza glabra roots and their PPAR-gamma ligand-binding activity.[Pubmed:20022509]

Bioorg Med Chem. 2010 Jan 15;18(2):962-70.

Bioassay-guided fractionation of the EtOH extract of licorice (Glycyrrhiza glabra roots), using a GAL-4-PPAR-gamma chimera assay method, resulted in the isolation of 39 phenolics, including 10 new compounds (1-10). The structures of the new compounds were determined by analysis of their spectroscopic data. Among the isolated compounds, 5'-formylglabridin (5), (2R,3R)-3,4',7-trihydroxy-3'-prenylflavane (7), echinatin, (3R)-2',3',7-trihydroxy-4'-methoxyisoflavan, kanzonol X, kanzonol W, shinpterocarpin, Licoflavanone A, glabrol, shinflavanone, gancaonin L, and glabrone all exhibited significant PPAR-gamma ligand-binding activity. The activity of these compounds at a sample concentration of 10microg/mL was three times more potent than that of 0.5microM troglitazone.

Prenylated flavonoids with PTP1B inhibitory activity from the root bark of Erythrina mildbraedii.[Pubmed:18175982]

Chem Pharm Bull (Tokyo). 2008 Jan;56(1):85-8.

Phytochemical study on an EtOAc-soluble extract of the root bark of Erythrina mildbraedii resulted in the isolation of six prenylated flavonoids 1-6. Based on physicochemical and spectroscopic analyses, their structures were determined to be new natural products Licoflavanone-4'-O-methyl ether (1), 2',7-dihydroxy-4'-methoxy-5'-(3-methylbut-2-enyl)isoflavone (2), and (3R)-2',7-dihydroxy-3'-(3-methylbut-2-enyl)-2''',2'''-dimethylpyrano[5''',6''' :4',5']isoflavan (3), along with three known compounds erythrinin B (4), abyssinin II (5), and parvisoflavone B (6). All the isolates, except for compound 4, inhibited PTP1B activity in vitro with IC(50) values ranging from 5.3 to 42.6 microM. This result further suggests that the prenyl group on the B ring of flavonoids plays an important role in suppressing the enzyme PTP1B.
