Shaoyao-Gancao decoction, a Chinese herbal formula, is composed of Paeoniae Radix alba and Glycyrrhiza Radix et rhizoma. It has been widely used to treat muscle spasms and asthma. However, little is known about the bioactive components of Shaoyao-Gancao decoction. In the present study, the bioactive compounds in water-extract of Shaoyao-Gancao decoction were separated by the immobilized β2 -adrenoceptor affinity column and identified using quadrupole time-of-flight mass spectrometry. The affinity constants of the separated compounds that bound to β2 -adrenoceptor were determined by frontal analysis...

No effective drug is currently available for treatment of enterovirus 71 (EV71) infection. Schizonepeta tenuifolia Briq. (ST) has been used as a herbal constituent of traditional Chinese medicine. We studied whether the aqueous extract of Schizonepeta tenuifolia Briq (STE) has antiviral activity. STE inhibited replication of EV71, as evident by its ability to diminish plaque formation and cytopathic effect induced by EV71, and to inhibit the synthesis of viral RNA and protein. Moreover, daily single-dose STE treatment significantly improved the survival of EV71-infected mice, and ameliorated the symptoms...

Scutellariae Radix (SR) and its bioactive flavones elicit a variety of effects in the brain. However, the brain uptake of individual SR flavones and its relationship to the elicited effects after SR administration remain unknown. Moreover, previous studies seldom measured pharmacokinetic and pharmacodynamic outcomes simultaneously. In the current study, the brain uptake of six major SR flavones and the anxiolytic behavior following oral administration of a SR extract at two clinically relevant doses (600 and 1200 mg/kg twice daily) were simultaneously investigated in mice (n=18 per group)...

Non-small cell lung cancer (NSCLC), one type of lung cancer, owns high rates of morbidity and mortality. B-Raf is one of the promising oncogenic drivers of NSCLC. Parthenolide, a natural product, is mainly extracted from the herbal plant Tanacetum parthenium. The effect of parthenolide on NSCLC cells and its potential as B-Raf inhibitor were studied in this study. It's shown that parthenolide exhibited the strong cytotoxicity against NSCLC cells with IC50 ranging from 6.07 ± 0.45 to 15.38 ± 1.13 μM. Parthenolide was also able to induce apoptosis, suppress proliferation and invasion in NSCLC cells...

The phenolic content/composition and antioxidant activity of hot/cold infusion and decoction from the leaves of Arbutus unedo were studied for the first time. 1,1-diphenyl-2-picrylhydrazyl (DPPH(●)), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical cation (ABTS(●+)), crocin-bleaching, copper-reducing, and liposome accelerated oxidation assays were used for the evaluation of the activity in vitro. In vivo, the extracts were examined for their ability to protect S. cerevisiae cells from H2O2 induced oxidative stress...

Similar to neoplastic tissues, growth and development of adipose tissue are thought to be angiogenesis-dependent. Since visceral adipose tissue (VAT) is associated with development and progression of nonalcoholic fatty liver disease (NAFLD), we hypothesized that angiogenesis inhibition would attenuate obesity-induced NAFLD. We fed C57BL/6J mice a low-fat diet (LFD, chow 10% kcal fat), a high-fat diet (HFD, 45% kcal fat) or HFD supplemented with the lemon-balm extract ALS-L1023 (HFD-ALS) for 15 weeks. ALS-L1023 reduced endothelial cell-tube formation in vitro...

Herbal medicines, dietary supplements, and other foods may pharmacokinetically and/or pharmacodynamically interact with carbamazepine (CBZ), which could lead to potential clinical consequences. Paeonia emodi (PE) is one of the herbs used as complementary therapy in the treatment of epileptic patients in some cultures, and may also be co-administered with CBZ. This study evaluates the effects of PE on the pharmacokinetics of CBZ and determines a possible mechanism of interaction. Rats were administered vehicle saline or PE (200mg/kg, p...

The fern plant Dryopteris uniformis has traditionally been used in herbal medicine and possesses many biological activities. This study was conducted to explore the endophytic bacterial diversity associated with D. uniformis and evaluate their antibacterial potential against foodborne pathogenic bacteria (FPB). Among 51 isolated endophytic bacteria (EB), 26 EB were selected based on their morphological characteristics and identified by 16S rRNA gene analysis. The distribution of EB was diverse in the leaf and the stem/root tissues...

Shuang-Huang-Lian injectable powder (SHL)-a classical purified herbal preparation extracted from Scutellaria baicalensis, Lonicera japonica, and Forsythia suspense-has been used against human adenovirus III (HAdV₃) for many years. The combination herb and its major bioactive compounds, including chlorogenic acid, baicalin, and forsythia glycosides A, are effective inhibitors of the virus. However, no comprehensive studies are available on the antiviral effects of SHL against HAdV₃. Moreover, it remains unclear whether the mixture of chlorogenic acid, baicalin, and forsythia glycosides A (CBF) has enhanced antiviral activity compared with SHL...

Gingko biloba leaves have been used as herbal medicine in China for 5000 years, and the standardized leaf extract (GB-STE) has some beneficial effects in the treatment of age-related, cardiovascular, and neurological diseases. The aim of this study was to investigate the renoprotective effects of the Gingko biloba extract (GbE) against the toxicity of a single and relatively low dose of carbon tetrachloride (CCl4). In male adult Wistar rats, we determined the urine flux, the concentration of total proteins in urine, the concentration of glucose in urine, and the concentration of malondialdehyde (MDA) in renal cortex as well as two markers of renal function (clearance of inulin and p-aminohippurate); we also compared the histological lesions caused by CCl4...

Poly-S-nitrosated human serum albumin (Poly-SNO-HSA) delivered and accumulated nitric oxide (NO) in tumors and induces apoptosis. Tumor hypoxia is strongly associated with malignant progression and tumor resistance to therapy. In this study, we examined the cytotoxic effect of Poly-SNO-HSA under hypoxia on the murine colon 26 adenocarcinoma (C26) cells in vitro and in vivo. Under hypoxia, at about 4 times LD50 dose of Poly-SNO-HSA in vitro, the reactive oxygen species production was hindered but apoptotic cells were induced via cGMP pathway as the effect was suppressed by a soluble guanylate cyclase inhibitor, NS2028...

Severe stomatitis may lead to the need to interrupt or discontinue cancer therapy and, thus, may affect control of the primary disease. Stomatitis may also increase the risk of local and systemic infection and significantly affects the quality of life and the cost of care. The present study was conducted to evaluate the efficacy of two traditional herbal medicines in controlling treatment-induced stomatitis in a small cohort of lung cancer patients treated with afatinib. All patients who were treated with afatinib for epidermal growth factor receptor (EGFR) mutated nonsmallcell lung cancer (NSCLC) between January, 2015 and March, 2016, were included in this study...

BACKGROUND: Chong-Myung-Tang (CMT) extract is widely used in Korea as a traditional herbal tonic for increasing memory capacity in high-school students and also for numerous body ailments since centuries. The use of CMT to improve the learning capacity has been attributed to various plant constituents, especially black ginseng, in it. Therefore, in this study, we have first investigated whether black ginseng-enriched CMT extracts affected spatial learning using the Morris water maze (MWM) test...

Esophageal cancer (EC) is the fourth and sixth leading cause of cancer-related deaths in China and United States, respectively. The dismal prognosis of EC is mainly attributed to distant metastases, which may not be overcome by chemotherapy alone. Hence, the use of alternative adjuvant treatments, such as herbal medicines, for metastatic EC remains a great desire of patients. Our previous study demonstrated the in vivo anti-tumor and in vitro anti-invasion activities of Andrographis paniculata (AP) in esophageal cancer...

Boswellic acids constitute a group of unique pentacyclic triterpene acids from Boswellia serrata with multiple pharmacological activities that confer them anti-inflammatory and anti-tumoral properties. A subgroup of boswellic acids, characterized by an 11-keto group, elevates intracellular Ca(2+) concentrations [Ca(2+)]i and causes moderate aggregation of human platelets. How different BAs and their mixtures in pharmacological preparations affect these parameters in activated platelets has not been addressed, so far...
