    Biological Activity
    Description: Liquiritigenin, is an estrogenic compound which acts as an agonist selective for the β-subtype of the estrogen receptor, possesses anti-inflammatory, antihyperlipidemic, and antiallergic effects. Liquiritigenin can dose dependently alleviate mechanical, thermal and cold hyperalgesia, it may be potentially useful novel treatments for neuropathic pain. It exhibits antitumour action in pituitary adenoma cells via Ras/ERKs and ROS-dependent mitochondrial signalling pathways.
    Targets: GSK-3 | TNF-α | IL Receptor | IkB | p65 | ROS | JNK | Caspase | Bcl-2/Bax | p38MAPK | ERK | MMP(e.g.TIMP) | IKK

    Liquiritigenin induces tumor cell death through mitogen-activated protein kinase- (MPAKs-) mediated pathway in hepatocellular carcinoma cells.[Pubmed: 24738081]
    Liquiritigenin (LQ), separated from Glycyrrhiza radix, possesses anti-inflammatory, antihyperlipidemic, and antiallergic effects.
    METHODS AND RESULTS:
    Our present study aims to investigate the antihepatocellular carcinoma effects of LQ both in cell and animal models. LQ strikingly reduced cell viability, enhanced apoptotic rate, induced lactate dehydrogenase over-release, and increased intracellular reactive oxygen species (ROS) level and caspase 3 activity in both PLC/PRL/5 and HepG2 cells. The expression of cleaved PARP, the hall-marker of apoptosis, was enhanced by LQ. LQ treatment resulted in a reduction of the expressions of B-cell lymphoma 2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-xL), and an increase of the phosphorylation of c-Jun N-terminal kinases (JNK) and P38. LQ-mediated cell viability reduction, mitochondrial dysfunction, apoptosis related protein abnormal expressions, and JNK and P38 activation were partially abolished by N-Acetyl-L-cysteine (a ROS inhibitor) pretreatment. Moreover, LQ suppressed the activation of extracellular signaling-regulated kinase (ERKs) and reduced the translocation of phosphor-ERKs from cytoplasm to nucleus. This antitumor activity was further confirmed in PLC/PRL/5-xenografted mice model. All these data indicate that the antihepatocellular carcinoma effects of LQ are related to its modulation of the activations of mitogen-activated protein kinase (MAPKs).
    CONCLUSIONS:
    The study provides experimental evidence supporting LQ as a potential therapeutic agent for hepatocellular carcinoma treatment.

    Liquiritigenin ameliorates TNBS-induced colitis in mice.[Pubmed: 25311527]
    The anti-inflammatory effects of Liquiritigenin, a major flavonoid isolated from Glycyrrhizae uralensis, have been reported in many inflammation models. However, its protective effects have not been reported in a colitis model. This study investigated the anti-inflammatory effect and mechanism of Liquiritigenin for trinitrobenzene sulfonic acid (TNBS)-induced colitis in mice.
    METHODS AND RESULTS:
    Male mice imprinting control regions (ICR) were randomly divided into five groups: normal, TNBS-induced colitis, colitis treated with Liquiritigenin at low dose (10 mg/kg) and high dose (20 mg/kg), or mesalazine (10 mg/kg). TNBS colitis induction was performed except for in the normal group, and they were treated with Liquiritigenin or mesalazine except control group. The treatment effect was measured after three days treatment, by body weight, colon length, macroscopic score, histological score, levels of cytokines (tumor necrosis factor-α, interleukin [IL]-1β, IL-6, and IL-10) in colon tissue as well as the nuclear factor kappa-light-chain-enhancer pathway of activated B cells (NF-κB) activation. Mice treated with high-dose Liquiritigenin showed significant body weight gain, inhibition of colon shortening, protective effect on histological damages, and myeloperoxidase activity of colon tissue compared with the control group. Furthermore, mice treated with high-dose Liquiritigenin experienced significantly suppressed tumor necrosis factor-α, IL-1β, and IL-6 as well as enhanced IL-10 expression (all P < 0.05). High-dose Liquiritigenin treatment group showed significant decreases in TNBS-induced phosphorylation of IKKβ, p65, and IκB-α.
    CONCLUSIONS:
    Liquiritigenin may ameliorate TNBS-induced colitis in mice by suppressing expression of pro-inflammatory cytokines through NF-κB pathway.

    Liquiritigenin alleviates mechanical and cold hyperalgesia in a rat neuropathic pain model.[Pubmed: 25022218]
    This study assessed the potential antinociceptive effects of Liquiritigenin, a plant-derived compound with transient receptor potential melastatin 3 blocking activity in a rat model of persistent neuropathic pain.
    METHODS AND RESULTS:
    Chronic constriction injury (CCI) to the sciatic nerve was induced in male Sprague-Dawley rats to model human peripheral neuropathic pain. Liquiritigenin (1, 3, or 9 mg/kg) was administered intraperitoneally to examine the effects on mechanical, thermal, and cold hyperalgesia using the von Frey test, plantar test, and cold plate test, respectively. A rotarod test was also conducted to examine motor function. Liquiritigenin dose dependently alleviated mechanical, thermal and cold hyperalgesia. In addition, daily repeated treatment with Liquiritigenin did not demonstrate significant antinociceptive tolerance in the measures of hyperalgesia. Within the doses studied, Liquiritigenin did not significantly affect motor performance.
    CONCLUSIONS:
    These results suggest that Liquiritigenin may be potentially useful novel treatments for neuropathic pain.

    Tacrine, an Oral Acetylcholinesterase Inhibitor, Induced Hepatic Oxidative Damage, Which Was Blocked by Liquiritigenin through GSK3-beta Inhibition.[Pubmed: 25747977]
    Although the cholinesterase inhibitor tacrine has been successfully used for the treatment of Alzheimer's disease, it is known to have hepatotoxic effects. Liquiritigenin (LQ), an active flavonoid in Glycyrrhizae radix, exerts protective effects against liver damage.
    METHODS AND RESULTS:
    This study investigated the toxic effect of tacrine on hepatocytes and the beneficial effect of LQ on tacrine intoxication in vivo and in vitro, and the underlying mechanism involved. In hepatocyte cell lines, tacrine induced cell death and oxidative stress, as indicated by decreases in cell viability and glutathione (GSH) contents, which were blocked by pretreatment with LQ. Fluorescent activated cell sorter (FACS) analysis revealed that LQ inhibited cellular H2O2 production and mitochondrial dysfunction induced by tacrine in HepG2 cells. Furthermore, LQ promoted inhibitory phosphorylation of glycogen synthase kinase-3β (GSK3β) and prevented decreases in GSK3β phosphorylation induced by tacrine. In rats treatment with tacrine at 30 mg/kg increased hepatic damage as assessed by blood biochemistry and histopathology. Administration of LQ (10 or 30 mg/kg/d, per os (p.o.)) or the hepatoprotective drug sylimarin (100 mg/kg/d) for 3 d inhibited elevations in alanine aminotransferase, aspartate aminotransferase, and histological changes induced by tacrine.
    CONCLUSIONS:
    These results show that LQ efficaciously protects the rat liver against tacrine-induced liver damage, and suggest that LQ is a therapeutic candidate for ameliorating the hepatotoxic effects of tacrine.
