dryopteris rossii/抗がん剤

Two new ichthyotoxic compounds, aspidin PB (8) and dryofragin (9), along with three known phloroglucinol derivatives (1-3) and five terpenoids, were isolated from the whole herbs of Dryopteris fragrans by toxicity-directed fractionation using Oryzias latipes (Japanese name; medaka). The structures

Cancer is one of the most major diseases that threatens human health and life. The aim of this work was to obtain novel anticancer molecules from D. fragrans, a kind of medicinal plant. The structure of the new compound was identified using spectroscopic data (¹H-NMR, 13C-NMR and two dimensions

The profiles and bioactivities of flavonoids extracted from Dryopteris erythrosora were investigated. The total flavonoid content in full plant of D. Erythrosora is about 14.33%. The main flavonoids in D. Erythrosora were identified as gliricidin 7-O-hexoside, apigenin7-O-glucoside, quercetin

OBJECTIVE The inhibitory effect of Dryopteris crassirhizoma on the proliferation of human metastatic prostate PC3-MM2 cells and the mechanism of action were examined to identify its anti-cancer properties. The effect of the extract on cell cycle progression and its combined cytotoxic effect with

As a part of screening studies for cancer chemopreventive agents (anti-tumor promoters) 33 Dryopteris phlorophenone derivatives have been evaluated. The compounds tested comprised of monomeric acylphloroglucinols (e.g. desaspidinol, aspidinol) as well as dimeric (e.g. aspidin, desaspidin), trimeric

Dryofragin, a phloroglucinol derivative extracted from Dryopteris fragrans (L.) Schott, was found to inhibit proliferation and induce apoptosis of tumor cells. However, the mechanism involved in the suppression of cancer cell metastasis by dryofragin remains unclear. Our study investigated the

Dryopteris crassirhizoma (DC) has a wide range of pharmacological effects, including antibacterial, anti‑influenza virus, anti‑tumor, anti‑reverse transcriptase and antioxidant effects. However, the inhibitory effect of DC on allergic inflammatory response remains unclear; therefore, the current

Dryofragin is a phloroglucinol derivative extracted from Dryopteris fragrans (L.) Schott. In this study, the anticancer activity of dryofragin on human breast cancer MCF-7 cells was investigated. Dryofragin inhibited the growth of MCF-7 cells in a time and concentration-dependent manner. The cell

The global burden of cancer continues to increase largely with the aging and growth of the world population. The purpose of the present work was to find new anticancer molecules from a natural source. We utilized chromatographic methods to isolate compounds from medicinal plant Dryopteris fragrans

Dryopteris fragrans is a valuable medicinal plant resource with extensive biological activities including anti-cancer, anti-oxidation, and anti-inflammation activities. This work aims to study further the cytotoxic constituents from Dryopteris fragrans. In this work, two new phenolic derivatives

There is growing use of anticancer complementary and alternative medicines (CAMs) worldwide. The purpose of the current study is to assess a sizeable variety of natural and plant sources of diverse origin, to ascertain prospective research directives for cancer treatment and potential new
