Panaxytriol, a polyacetylenic compound, isolated from red ginseng (Panax ginseng C.A. Meyer), was studied to determine its effects on the growth and cell cycle of tumor cell lines. The compound showed both significant cytotoxicity and inhibition of DNA syntheses in various tumor cells tested. For
Panaxytriol is a nutraceutical-based active constituent of Korean red ginseng and is reported to exhibit potent anti-tumor properties. Its activity may be in part due to its induction of phase 2 chemoprotective enzymes. Its unique properties may have important implications in cancer therapeutics.
Polyacetylenic alcohols such as panaxytriol, panaxynol and panaxydol isolated from the roots of Panax ginseng C. A. MEYER have antiproliferative activity against various cultured tumor cells. Anti-panaxytriol antibody was obtained by immunizing rabbits with panaxytriol-bovine serum albumin
A polyacetylenic alcohol, panaxytriol, isolated from Panax ginseng C. A. Meyer inhibits both tumor cell growth in vitro and the growth of B16 melanoma transplanted into mice. Our preliminary studies indicated that panaxytriol localizes to the mitochondria in human breast carcinoma cells (Breast
Polyacetylenic alcohol, panaxytriol, which was isolated from Panax ginseng C. A. Meyer, has antiproliferative activity against several kinds of tumor cells. In this paper, the effect of panaxytriol on the cytotoxicity of mitomycin C (MMC) against a human gastric carcinoma cell line, MK-1, was
An antitumor-active substance was obtained from the residue of the ethyl acetate extract of red ginseng, a traditional Chinese medicine, by chromatography on a silica gel column. From the proton and carbon-13 nuclear magnetic resonance spectra, it was identified as
A new type of cell growth inhibitory substance was isolated and purified from a powder of the root of Panax ginseng C.A. Meyer, which has been commonly used for the treatment of various disease as a commercial medical drug by the name of Korean Red Ginseng Powder. Data from the infrared spectra,
We here present an optical method for monitoring the activity of the inducible aldo-keto reductases AKR1C2 and AKR1C3 in living human cells. The induction of these enzymes is regulated by the antioxidant response element (ARE), as demonstrated in recent literature, which in turn is dependent on the
We describe herein the discovery of a series of panaxytriol (PXT)-derived polyacetylene small molecules with promising cytoprotective activity. In mouse xenograft models, we have demonstrated the capacity of our synthetic analogs to mitigate a range of cancer therapeutic agent-induced toxicities,
This brief article focuses on two aims: i) To investigate the in vitro pharmaco-dynamic interactions of combining synthetic potent microtubule targeting anticancer agent, Fludelone (FD) with cyto-protective agent, Panaxytriol (PXT) derived from Panax ginseng, and ii) To illustrate step-by-step
Lipid-soluble ginseng extracts (LSGE) is known to inhibit many types of cancer cells through arresting cell cycle and inducing apoptosis. Usually, normal cells are can also be damaged by anti-tumor reagents. The plasma membrane redox system (PMRS) is enhanced to compensate mitochondrial dysfunction
Column chromatographic separation of the roots of cultivated-wild ginseng (Jangnoisam) led to the isolation of seven polyacetylenes (1-7). Their structures were determined by spectroscopic methods to be panaxynol (1), ginsenoyne-A (2), panaxydol (3), 10-methoxy heptadeca-1-ene-4, 6-dyne-3, 9-diol
Methanol extracts of 36 samples of 21 Umbelliferae plants were screened for polyacetylenic compounds using the ELISA for panaxytriol, and their antiproliferative activity was checked by MTT assay using the tumor cell lines MK-1, HeLa and B16F10. The presence of antiproliferative polyacetylenes was
Antitumor polyacetylenic alcohol, panaxynol, was isolated and purified from a powder of the root of Panax ginseng C.A. Meyer. Panaxynol inhibited the growth of various kinds of cultured tumor cell lines in a dose-dependent manner. In this paper we demonstrated the first specific antibody production
