Panaxydol is a naturally occurring non-peptidyl small molecule isolated from the lipophilic fractions of Panax notoginseng, a well-known Chinese traditional medicine. Previous studies have shown that panaxydol inhibited the growth of various kinds of malignant cell lines. To date, there has been no
OBJECTIVE
Panaxydol is a naturally occurring non-peptidyl small molecule isolated from the lipophilic fractions of Panax notoginseng, a well-known Chinese traditional medicine. In this study, we aimed to investigate the effects of panaxydol on growth inhibition and its mechanisms in C6 rat glioma
Panaxydol isolated from the lipophilic fractions of Tienchi ginseng (Panax notoginseng) induces growth inhibition and differentiation of rat C6 glioma cells. The underlying molecular mechanisms are not completely understood. In the present study, we identified phosphatidylinositol 3-kinase (PI 3-K)
Panaxynol and panaxydol are naturally occurring polyacetylenes, isolated from the lipophilic fractions of Panax notoginseng, that exert anti-proliferative effects against malignant cells. However, to the best of our knowledge, no study concerning the inhibitory effects of the two polyacetylenes on
Panaxydol (PND) is one of the main non-peptidyl small molecules isolated from the lipophilic fractions of Panax notoginseng. The present study was carried out to demonstrate the potential effects of panaxydol on the induction of differentiation of human liver carcinoma cell lines SMMC-7721. Cell
Nerve growth factor (NGF) promotes axonal growth in PC12 cells primarily by regulating the RTK-RAS-MEK-ERK pathway. Panaxydol, a polyacetylene isolated from Panax notoginseng, can mimic the effects of NGF. Panaxydol promotes neurite outgrowth in PC12 cells, but its molecular mechanism remains
Panaxydol (PX), a polyacetylenic compound isolated from the roots of Panax notoginseng, is found to possess various biological functions. However, its protective effects against aristolochic acid (AA)-induced renal injury have not been elucidated yet. The present study was undertaken to elucidate
Panaxydol, a polyacetylenic compound derived from Panax ginseng has been reported to suppress the growth of cancer cells. However, the molecular mechanisms underlying cell cycle arrest by this compound in non-small cell lung cancer (NSCLC) are unknown. Our study found that panaxydol treatment
OBJECTIVE
To establish an HPLC method for simultaneous determination of panaxynol and panaxydol from the fibrous root of Panax ginseng.
METHODS
The analysis was performed on Elite C18 column (4.6 mm x 150 mm, 5 microm) with mobile phase gradient of CH3CN-water at a flow rate of 1.0 mL x min(-1). The
We reported previously that panaxydol, a component of Panax ginseng roots, induced mitochondria-mediated apoptosis preferentially in transformed cells. This study demonstrates that EGFR activation and the resulting ER stress mediate panaxydol-induced apoptosis, and that panaxydol suppresses in vivo
Polyacetylenic compounds of Panax ginseng roots have been shown to inhibit growth of several human malignant tumor cell lines. Panaxydol is known to be one of the cytotoxic polyacetylenic compounds of P. ginseng. In this study, we first showed that panaxydol decreased markedly the proliferation, and
The natural formation of the bioactive C17-polyacetylenes (-)-(R)-panaxynol and panaxydol was analyzed by 13C-labeling experiments. For this purpose, plants of Panax ginseng were supplied with 13CO2 under field conditions or, alternatively, sterile root cultures of P. ginseng were supplemented with
Cultivated wild ginseng (cWG), called SanYangSanSam, has been used clinically in patients with chronic fatigue in Korea. Little is known about effects of the ginseng distilled (volatile) components produced during evaporizaiton. Recently, we first identified one major component from Panax ginseng roots have long been used as a medicinal herb in oriental countries. We have investigated anti-proliferative effects of lipid soluble Panax ginseng components on human renal cancer cell lines. Petroleum ether extract of Panax ginseng roots (GX-PE) or its partially purified preparation
A method for simultaneous determination of ginsenosides and polyacetylenes in Panax quinquefolium L. (American ginseng) roots was developed. The ginsenosides Rb1, Rb2, Rc, Rd, Re, Rg1, Ro, malonyl-Rb1, malonyl-Rc, and malonyl-Rd and the polyacetylenes falcarinol and panaxydol were extracted from
