The active metabolite of the novel immunosuppressive agent leflunomide has been shown to inhibit the enzyme dihydroorotate dehydrogenase (DHODH). This enzyme catalyzes the fourth step in de novo pyrimidine biosynthesis. Self-organizing molecular field analysis (SOMFA), a simple three-dimensional quantitative structure-activity relationship (3D-QSAR) method(More)
AIM OF THE STUDY The objectives of this study were to investigate the adjuvant anti-tumor effects of Antrodia camphorate in human hepatoma cells (C3A and PLC/PRF/5) which are resistance to most anti-tumor agents, elucidate the possible regulation pathways, and measure the tumor growth and survival rate in xenograft-nude mice after combined with anti-tumor(More)
AIM To determine the active ingredient of Niuchangchih (Antrodia camphorata) responsible for its anti-inflammatory effects and the relevant molecular mechanisms. METHODS Five major antcins (A, B, C, H, and K) were isolated from fruiting bodies of Niuchangchih. Structural similarity between the antcins and 2 glucocorticoids (cortisone and dexamethasone)(More)
Antrodia camphorata (niu-chang-chih) is a fungus native to Taiwan that is believed to be effective in preventing diseases. This study demonstrates that 0.2-2% v/v ethanol extracts of A. camphorata cultivated by solid-state fermentation (SACE) can effectively impede the proliferation of human non-small cell lung carcinoma A549 cells but not primary human(More)
Diabetes mellitus is the most common chronic disease in the world, and a wide range of drugs, including Chinese herbs, have been evaluated for the treatment of associated metabolic disorders. This study investigated the potential hypoglycemic and renoprotective effects of an extract from the solid-state fermented mycelium of Cordyceps sinensis (CS). We(More)
UNLABELLED BACKGROUND Xiao-Yao-San (XYS) is a Chinese medicinal formula for treating anxiety and depression. This study aims to evaluate the use of a room-temperature super-extraction system (RTSES) to extract the major active components of XYS and enhance their psycho-pharmacological effects. METHODS The neuroprotective roles of XYS/RTSES against(More)
Antrodia camphorata, unique fungal specie, has been used as a folk medicine in Taiwan for many years. The purpose of this study was to compare the extracts from the solid-state culture of A. camphorata co-fermented with Chinese medicinal herb (AC-CF) with two other extracts from fruiting bodies (AC-FB) or solid-state culture (AC-SS), for their anti-tumor(More)
It has been reported that medicinal mushrooms might induce different types of immune responses. Anthodia camphorata (A. camphorata) has attracted much attention for its therapeutic effects in treating hepatoma. We tested this anti-tumor effects using immunomodulation of macrophages and extracts of A. camphorata. We evaluated the anti-proliferation effects(More)
In our previous study, a series of novel cyclic cyanoguanidine compounds, eg. 5-substituted 2-cyanoimino-4-imidazodinone and 2-cyanoimino-4- pyrimidinone derivatives have been successfully synthesized and showed remarkable cytotoxicity in several cancer cell lines. In this present study, it is our aim to screen more potential candidates among the cyclic(More)
Energy medicine (EM) provides a new medical choice for patients, and its advantages are the noninvasive detection and nondrug treatment. An electromagnetic signal, a kind of EM, induced from antibiotic coupling with weak, extremely low-frequency pulsed electromagnetic fields (PEMFs) is utilized for investigating the growth speed of Escherichia coli (E.(More)
