Hepatoprotective Effect of Mycelium Powder on Alcohol-Induced Liver Damage.

Background/objectives: , also known as "Niuchangchih" in Taiwan, is a unique medicinal mushroom native to Taiwan. It is used in traditional medicine to treat various health conditions. In this study, we investigated the efficacy of mycelia on alcohol-induced liver damage, both in vitro and in vivo, in a Good Laboratory Practice (GLP) facility.

Clinical Benefits of Golden- Containing Antroquinonol in Liver Protection and Liver Fat Reduction After Alcoholic Hepatitis.

It has been reported that antroquinonol extracted from Golden- exerts protective effects on liver function both . However, the protective effects of Golden- on liver function have not been fully investigated in human clinical studies. Therefore, the present study aimed to evaluate the beneficial effects of Golden- on hepatic function after alcohol consumption in human subjects.

Antroquinonol blocks Ras and Rho signaling via the inhibition of protein isoprenyltransferase activity in cancer cells.

Antroquinonol is the smallest anticancer molecule isolated from Antrodia camphorata thus far. The ubiquinone-like structure of Antroquinonol exhibits a broad spectrum of activity against malignancies in vivo and in vitro. However, the mechanism of action of Antroquinonol remains unclear.

Antroquinonol D, isolated from Antrodia camphorata, with DNA demethylation and anticancer potential.

DNA methyltransferase 1 (DNMT1) catalyzes DNA methylation and is overexpressed in various human diseases, including cancer. A rational approach to preventing tumorigenesis involves the use of pharmacologic inhibitors of DNA methylation; these inhibitors should reactivate tumor suppressor genes (TSGs) in tumor cells and restore tumor suppressor pathways. Antroquinonol D (3-demethoxyl antroquinonol), a new DNMT1 inhibitor, was isolated from Antrodia camphorata and identified using nuclear magnetic resonance.

Metabolites of antroquinonol found in rat urine following oral administration.

Four metabolites (1-4) of antroquinonol from rat urine, collected within 24 h after oral administration of antroquinonol, were characterized by HPLC-SPE-NMR. Compounds 1-4 were further isolated by semipreparative HPLC for structure confirmation. Their structures were elucidated on the basis of 1D and 2D NMR spectroscopic analyses and HRESIMS data.

Photon pair generation and pump filtering in nonlinear adiabatic waveguiding structures.

We propose a novel integrated scheme for generation of Bell states, which allows simultaneous spatial filtering of pump photons. It is achieved through spontaneous parametric down-conversion in the system of nonlinear adiabatically coupled waveguides. We perform detailed analytic study of photon-pair generation in coupled waveguides and reveal the optimal conditions for the generation of each particular Bell state.

Antroquinonol, a natural ubiquinone derivative, induces a cross talk between apoptosis, autophagy and senescence in human pancreatic carcinoma cells.

Pancreatic cancer is a malignant neoplasm of the pancreas. A mutation and constitutive activation of K-ras occurs in more than 90% of pancreatic adenocarcinomas. A successful approach for the treatment of pancreatic cancers is urgent.

Constituents of Polyalthia longifolia var. pendula.

Three new clerodane-type diterpenes, 6alpha,16-dihydroxycleroda-3,13-dien-15-oic acid (1), 6alpha,16-dihydroxycleroda-4(18),13-dien-15-oic acid (2), and 4alpha,18beta-epoxy-16-hydroxyclerod-13-en-15-oic acid (3), and four new protoberberine alkaloids, (-)-8-oxo-10-hydroxy-2,3,9-trimethoxyberberine (4), (-)-8-oxo-2,11-dihydroxy-3,10-dimethoxyberberine (5), (-)-8-oxo-11-hydroxy-2,3,9,10-tetramethoxyberberine (6), and (-)-8-oxo-2,10-dihydroxy-3,9,11-trimethoxyberberine (7), together with 11 known substances, were isolated from a methanol extract of the stems of Polyalthia longifolia var. pendula. The structures of 1-7 were elucidated on the basis of spectroscopic data analysis.

Antroquinonol displays anticancer potential against human hepatocellular carcinoma cells: a crucial role of AMPK and mTOR pathways.

5'AMP-activated protein kinase (AMPK) and the mammalian target of rapamycin (mTOR) are two serine/threonine protein kinases responsible for cellular energy homeostasis and translational control, respectively. Evidence suggests that these two kniases are potential targets for cancer chemotherapy against hepatocellular carcinoma (HCC). Antroquinonol that is isolated from Antrodia camphorate, a well-known Traditional Chinese Medicine for treatment of liver diseases, displayed effective anticancer activity against both HBV DNA-positive and -negative HCC cell lines.

An Extract of Antrodia camphorata Mycelia Attenuates the Progression of Nephritis in Systemic Lupus Erythematosus-Prone NZB/W F1 Mice.

Antrodia camphorata is used in folk medicine for the treatment of inflammation syndromes and liver-related diseases in Taiwan. The goal of this study was to evaluate the efficacy of the mycelial extract of A. camphorata (ACE) for the treatment of systemic lupus erythematosus (SLE) in SLE-prone NZB/W F1 mice.

A new cytotoxic agent from solid-state fermented mycelium of Antrodia camphorata.

Antroquinonol ( 1), an ubiquinone derivative, was isolated from the solid-state fermented mycelium of Antrodia camphorata (Polyporaceae, Aphyllophorales), a parasitic fungus indigenous to Taiwan. The structure of compound 1 was elucidated by the analysis of their spectroscopic data. Its cytotoxic activities were evaluated against MCF-7, MDA-MB-231 (human breast carcinoma), Hep3B, HepG2 (human liver carcinoma) and DU-145, LNCaP (human prostate carcinoma) cell lines, and the IC (50) values ranged from 0.

Classification of Aurantii Fructus samples by multivariate analysis.

Twenty commercial samples of Aurantii Fructus Immaturus (Poncitrus trifoliata) and 30 of Aurantii Fructus Maturus (Citrus aurantium and C. wilsonii) were collected from the Taiwan and China herbal markets. The contents of 12 constituents in these samples were determined by HPLC and were used to assess the potential relationships with their plant origins.

Origin identification on the commercial samples of Aurantii Fructus.

A total of 50 commercial samples of Aurantii Fructus, originating from Poncitrus trifoliata for Aurantii Fructus Immaturus, Citrus aurantium, and C. wilsonii for Aurantii Fructus Maturus, respectively, were collected from Taiwan and China herbal markets. Contents of the constituents in the samples were determined within 60 min using a developed HPLC method, which had been validated in terms of precision, repeatability, and accuracy.
