Estrogens are biologically active steroid hormones mainly released from the ovary by ovarian secretion of estrogen into the circulating blood to regulate or function at the distal target. Estrogens play an important role in the central nervous system, cardiovascular system and immune system, especially for post-menopausal women. Panax ginseng Mayer has been reported to relieve women's menopausal symptoms and affect estrogen activities. However, the mechanism of its estrogen regulation has not yet been clearly investigated...

Ginsenoside Rh2 (Rh2) is one of the major bioactive ginsenosides in Panax ginseng. However, the oral bioavailability of Rh2 is low, with P-glycoprotein (P-gp) and CYP3A4 being reported to be the main factors. The purpose of the present study was to determine the enhancing effect of piperine on the oral bioavailability as well as bioactivity of Rh2. The inhibitory effect of piperine on P-gp and CYP3A4 was determined using a Caco-2 monolayer model and a recombinant CYP3A4 metabolic system, respectively. The pharmacokinetics of oral Rh2 (10 mg·kg-1 ) administered alone or in combination with piperine (10 and 20 mg·kg-1 ) was performed in rats...

Microorganisms have been regarded as important sources of novel bioactive natural products. In this study, we evaluated the anti-cancer activity and the potential mechanism of Bacillus amyloliquefaciens AK-0 newly isolated from the rhizosphere soil of Korean ginseng. The ethyl acetate fraction from the culture medium of B. amyloliquefaciens AK-0 (EA-AK0) inhibited markedly the proliferation of human colorectal cancer cells such as HCT116, SW480, LoVo and HT-29. EA-AK0 effectively decreased cyclin D1 protein level in human colorectal cancer cells, while cyclin D1 mRNA level was not changed by EA-AK0 treatment...

SIGNIFICANCE: Obesity may increase susceptibility to chronic pain often due to poor diet. Diet has potential to be used as treatment for pain. The current study investigates the use of a novel translatable diet to act as a preventative (i.e., prior to surgery) or an intervention (i.e., following an injury). BACKGROUND: Obesity and chronic pain are prevalent concerns. Pain is frequently experienced in weight bearing joints, but is common in other areas of the body as well, suggesting other factors...

The incidence of breast cancer has been increasing in China and the age of breast cancer onset is earlier compared with Western countries. Compounds commonly used in Traditional Chinese Medicine (TCM) are an important source of anticancer drugs. Ginseng is one of the most common medicines used in TCM. Ginsenosides, which are saponins found in the ginseng plant, are the major active components responsible for the chemopreventive effects of ginseng in cancer. However, the mechanisms by which ginsenosides exert their anticancer effects remain elusive...

Ginsenosides Rb1, Rh1, Rg1 and Rg3 are known as the main active components extracted from the roots of the Panax ginseng C.A. Meyer, and were reported to have immunoregulatory effects. Disruption of B-cell immune regulation during the pathogenesis of systemic lupus erythematosus (SLE) may lead to the production of large amounts of antibodies. The present study investigated the effects of the four ginsenoside monomers on B-cell immune regulation and observed that they inhibited the proliferation and secretion of B cells induced by LPS, caused an upregulation of the expression of apoptosis-associated proteins Fas/Fas ligand and caspase-3, the expression of FcγRIIB (CD32) as well as the proportion of inactive B cells (CD19+CD27-)...

Acanthopanax senticosus, also known as Siberian ginseng, is widely distributed throughout northern Asia and used in traditional Chinese medicine; it has been reported to prevent a number of diseases. However, the association between the antitumour and immunostimulatory activities of polysaccharide extracted from A. senticosus (ASPS) remains to be elucidated. The aim of the present study was to investigate the anti-tumour and immunomodulatory effects of polysaccharide extracted from ASPS on Crocker sarcoma S180, hepatic carcinoma H22 and uterine cervical carcinoma U14 tumour cell lines implanted in mice...

Four representative Δ20-ginsenosides, namely ginsenosides Rh4 (1), (20E)-Rh3 (2), Rg6 (3) and Rk1 (4) from Panax Ginseng were chemically synthesized for the first time. Dehydration of the naturally occurring 20(S)-protopanaxatriol and 20(S)-protopanaxadiol provided all type of Δ20-sapogenins, which were separated due to a judicious choice of protecting groups. The Δ20-sapogenins were then directly glycosylated with glycosyl ortho-alkynylbenzoate donors under the catalysis of Ph3PAuNTf2 as key steps. The neutral conditions of the glycosylations were crucial to prevent the acid-labileΔ20,21 double bond from isomerization...

Ginsenosides, the major active constituents of ginseng, have been demonstrated possess anti-diabetic, anti-inflammatory effects. Ginsenoside Rb2 (Rb2) is the most abundant saponin in Panax ginseng, this study investigates the role of Rb2 in the anti-hyperglycemic mechanism of insulin-sensitive cell lines 3T3-L1 adipocytes as well as high fat diet-induced obesity mice. Glucose uptake of 3T3-L1 adipocytes was measured. The insulin signaling cascade, including insulin AKT, insulin receptor (IR) beta-subunit, IR substrate (IRS) -1, phosphatidylinositol 3-kinase (PI3K) were also examined...

BACKGROUND: Sailuotong (SLT) is a standard Chinese preparation made from extracts of Panax ginseng (ginseng), Ginkgo biloba (ginkgo), and Crocus sativus (saffron). Preliminary clinical trials and animal experiments have demonstrated that SLT could improve cognition of vascular dementia (VD). PURPOSE: To avoid incident drug-drug interaction which is easily encountered in patients of VD, the potential influence of SLT on main drug-metabolic cytochromes P450 enzymes (CYP450) was investigated...

During the last few decades, cancer has mushroomed as a major health issue; and almost all drugs used for its therapy are very toxic with lethal side effects. Complementary and alternative medicines gain popularity among health professionals in recent era owing to its preventive mechanism against side effect chemotherapeutic drugs. Efforts are focused by scientists to isolate compounds from medicinal plant that have chemotherapeutic attributes; and ability to neutralize the side effects of chemotherapy. Ginseng is an oriental medicinal recipe from Araliceae family and Panax species...

The Traditional Chinese Medicine (TCM) theory that "kidneys give rise to marrow, and the brain is the sea of marrow" has been a guide for the clinical application of kidney, qi and blood tonics for prevention and treatment of dementia and improvement in memory. As low resistance end-organs, both the brain and the kidneys are subjected to blood flow of high volumes throughout the cardiac cycle. Alzheimer's disease and vascular dementia are two common causes of dementia, and it is increasingly recognized that many older adults with dementia have both AD and vascular pathologies...

Cylindrocarpon destructans is an ascomycete soil-borne pathogen that causes ginseng root rot. To identify effective biocontrol agents, we isolated several bacteria from ginseng cultivation soil and evaluated their antifungal activity. Among the isolated bacteria, one isolate (named JH7) was selected for its high antibiotic activity and was further examined for antagonism against fungal pathogens. Strain JH7 was identified as a Chromobacterium sp. using phylogenetic analysis based on 16S rRNA gene sequences...
