Licorice flavonoid (LF) is the main component of Glycyrrhizae Radix et Rhizoma, a "medicine food homology" herbal medicine, which has anti-digestive ulcer activity, but mechanism in anti-gastric (GU) remains to be elucidated. In this study, we manifested that LF increased viability human gastric mucosal epithelial (GES-1) cells, attenuated ethanol (EtOH)-induced manifestations, reduced histological injury, suppressed inflammation, and restored barrier GU rats. After therapy, EtOH-induced gut...

Glycyrrhiza uralensis contains many secondary metabolites with a wide range of pharmacological activities. Drought stress acts as positive regulator to stimulate the production medicinal active component in G. uralensis, however, underlying mechanism remains unclear. The aim this work is investigate accumulation and regulatory pharmaceutical ingredients under drought stress. materials aerial underground parts seedlings treated by 10% PEG6000 for 0, 2, 6, 12, 24 h were used RNA sequencing...

Abstract Licorice flavonoids (LCFs) have been widely used in food care and medical treatment due to their significant antioxidant activities. However, the molecular mechanism of activity remains unclear. Therefore, network pharmacology, ADMET, density functional theory (DFT), docking, dynamics (MD) simulation were employed explore effects LCF. The pharmacology ADMET studies showed that active molecules kumatakenin (p K a = 6.18), licoflavonol 6.86), topazolin 6.21) LCF are key components...

Excessive oxygen free radicals can lead to aging, cancer, and other diseases. Therefore, searching for effective antioxidants scavenge has become the focus of modern medicine. In this study, molecular mechanism Licorice Green Tea Beverage (LGTB) in scavenging was investigated by means network pharmacology, docking experimental verification. Network pharmacology studies have shown that paeonol, eugenol, cinnamaldehyde, swertisin, rutin, glycyrrhetinic acid, oleic, pelargonidin-3-O-glucoside...

Licorice flavonoids (LCFs) are natural isolated from Glycyrrhiza which known to have anti-melanoma activities in vitro. However, the molecular mechanism of LCF has not been fully understood. In this study, network pharmacology, 3D/2D-QSAR, docking, and dynamics (MD) simulation were used explore anti-melanoma. First all, we screened key active components targets by pharmacology. Then, logIC50 values top 20 compounds predicted 2D-QSAR pharmacophore model, seven highly successfully. An optimal...

The purpose of the present study was to investigate cardioprotective effects Glycyrrhiza uralensis extract (GUE) against doxorubicin (DOX)-induced cardiotoxicity. Imprinting control region (ICR) mice were treated with saline, DOX (20 mg/kg intraperitoneal [ip] for once), GUE (100 intragastric [ig] 8 days), co-treatments and ig amifostine intravenous [iv] respectively. Serum levels lactate dehydrogenase (LDH) creatine kinase isoenzyme (CK-MB), glutathione peroxidase (GSH-P X ) activity, (GSH)...

We applied a label-free proteomic method to explore the mechanisms of Licorice flavonoid anti-acne effects in rat. Acne model was established back rats as group (MDL), then treated with licorice (LCF), while none control groups (CTR). In MDL, 314 differentially expressed proteins (DEPs) and 27 significantly (SDEPs) were identified compared what CTR. While LCF, 359 DEPs 15 SDEPs comparison MDL. Bioinformatics analysis showed that pathways related metabolism, tight junction, PI3K-Akt...

The present study was to systematically evaluate different licorice flavonoids (LFs) compounds release behaviors from the single payload hydrogel and LFs extracts hydrogels based on drug solubility in medium (DSRM), intermolecular strength of "release steric hindrance" (RSH). Two kinds (LFs 1: 2 = 5:1, W/W) were prepared with Carbopol 940 (CBP) as thickener, ten according actual content 1 extracts. mechanisms confirmed by vitro experiments molecular dynamic simulation analysis, evaluated...

Purpose: To test how glycyrrhizin (GLY) affects mouse corneal epithelial cells (MCEC) and the diabetic murine cornea. Methods: Viability of MCEC grown under normal or high glucose (HG) with/without GLY was tested by an MTT assay. In addition, C57BL/6 mice were injected with streptozotocin a subset control received in their drinking water. mRNA protein levels proinflammatory oxidative stress molecules reverse transcription-polymerase chain reaction (RT-PCR) both models. Ex vivo studies using...

The dynamic drug release mechanisms from Carbomer 940 (CP) hydrogels have not been systematically explored elsewhere. This study aimed to investigate the quantitative structure-activity relationship of licorice flavonoids (LFs) compounds on their CP based LFs-CP interactions and solubility in medium. Ten were formulated, vitro was conducted. intermolecular forces systems characterized by FTIR, molecular docking simulation. LFs classified into I (high-release capability) II (low-release...

Skeletal muscle wasting and weakness with mitochondrial dysfunction (MD) are major pathological problems in burn injury (BI) patients. Fibrinogen levels elevated plasma is an accepted risk factor for poor prognosis many human diseases, also designated one of damage-associated molecular pattern (DAMPs) proteins. The roles upregulated fibrinogen on changes critical illness including BI unknown. hypothesis tested was that BI-upregulated plays a pivotal role the inflammatory responses MD...
