Abstract:
The present invention relates to the novel use of panduratin derivatives or an extract of Boesenbergia pandurata for promoting muscle mass growth, fighting fatigue, and enhancing exercise performance capability. More particularly, the present invention relates to a composition for enhancing exercise performance capability, promoting muscle mass growth, and fighting fatigue, which comprises panduratin derivatives or salts thereof, or an extract of Boesenbergia pandurata, as active ingredients, and which promotes muscle mass growth and recovery from fatigue to improve mobility. The present invention also relates to a method for improving exercise performance capability, promoting muscle mass growth, and fighting fatigue, which involves injecting panduratin derivatives or salts thereof, or an extract of Boesenbergia pandurata, into an individual requiring same. The panduratin derivatives or the extract of Boesenbergia pandurata of the present invention can be used safely with no adverse effects, and increases the expression of PPAR d in the muscles, thus exhibiting excellent effects in promoting muscle mass growth, recovery from fatigue, and an enhancement in exercise performance capability such as an enhancement in mobility.
Abstract:
To study different types of thrombolytic agents, both thrombolysis and stimulation of fucoidan were studied in a mouse model of ferric chloride-induced arterial thrombosis and were compared with those of a heparin and tissue plasminogen activator (t-PA). Thrombosis was induced by applying a filter paper saturated with 5% FeCl3 to the left carotid artery. 20 minutes after complete occlusion, several test preparations including a fucoidan source from Undaria pinnatifida sporophylls were intravenously injected to each mouse group by various dosages of 10-200 mg/kg-1. To study the stimulation effect of fucoidan with respect to t-PA, fucoidan added in a predetermined amount of t-PA was injected by a dose of 1-10 mg/kg. Then, the time to reperfusion was measured. As a result, an occluded aorta was dose-dependently reperfused, and the reperfusion was observed at 37.5±12.4 minutes after the administration of 100 mg/kg-1 of unfractionated fucoidan. The time to reperfusion was retarded to 55.0±8.0 minutes when a large amount of fucoidan such as 1 g/kg-1 was administered to a mouse provided with low molecular weight fucoidan (LMWF). Reperfusion occurred at 16.67 minutes after administration in a mouse of a control group provided with 20 mg/kg-1 of t-PA. On the contrary, reperfusion was not observed in an occluded mouse provided with heparin (p
Abstract:
The present invention relates to a composition for preventing and treating muscle diseases or improving muscular function, containing, as an active ingredient, at least one selected from the group consisting of morusin, kuwanon G, and a Mori Cortex Radicis extract. The Mori Cortex Radicis extract, morusin, or kuwanon G, according to the present invention, has an effect of remarkably enhancing muscular function by increasing the expression of p-mTOR protein involved in muscular protein synthesis, inhibiting the expression of mRNAs of MuRF-1 and atrogin-1 involved in muscular protein degradation, and increasing the expression of mRNAs of MyoD and myogenin involved in muscle differentiation. In addition, the present invention is a natural product so as to be used safely without side effects, thereby being usable in drugs, food, or cosmetics.
Abstract:
The present invention relates to a novel use of panduratin derivative or Boesenbergia pandurata extract. More specifically, the present invention relates to: a composition containing panduratin derivative or Boesenbergia pandurata extract denoted by chemical formulas 1 to 3 as an active ingredient for preventing and treating/relieving metabolic disease; a method for treating metabolic disease characterized by administering effective amount of panduratin derivative or Boesenbergia pandurata extract to a needed individual; a use of the panduratin derivative or Boesenbergia pandurata extract to manufacture a formulation for preventing and treating/relieving metabolic diseases. The metabolic disease is selected from the group consisting of obesity, hyperlipidemia, hypercholesterolemia, and diabetes. The present invention provides a novel use of the panduratin derivative or Boesenbergia pandurata extract. The panduratin derivative or Boesenbergia pandurata extract of the present invention has an effect on metabolic disease such as obesity, hyperlipidemia, hypercholesterolemia, and diabetes by reducing a factor relating to the metabolic disease such as weight, body fat, or lipid content. Thus, the present invention provides a novel means which is safely used as a natural substance without side effects and is effective in preventing and treating/relieving metabolic diseases through weight loss and body fat reduction.
