Abstract:
The present invention relates to novel uses of capsosiphon fulvescens extract or compounds isolated therefrom for preventing or treating diabetic complications and, more specifically, to a pharmaceutical composition and a health supplement for preventing or treating diabetic complications which include capsosiphon fulvescens extract, soluble extract of non-polar solvent, or compounds isolated therefrom (capsofulvesin A, capsofulvesin B, chalinasterol) as active ingredients. The capsosiphon fulvescens extracts or compounds isolated therefrom (capsofulvesin A, capsofulvesin B, chalinasterol) have excellent suppression activities on aldose reductase and excellent suppression activities on final glycation products. Therefore, the capsosiphon fulvescens extracts or compounds isolated therefrom can be utilized as medicines such as pharmaceutical compositions and health supplements for preventing or treating diabetic complications so that the value of the capsosiphon fulvescens extracts or compounds isolated therefrom can be extremely high when applying in food and medical industries. Specially, the capsosiphon fulvescens extracts or compounds isolated therefrom in the present invention are substances derived from natural substances and have stability without cytotoxicity so that the compositions of the present invention which includes the same as active ingredients can be safely used for long time.
Abstract:
The present invention relates to novel uses of prevention or treatment of diabetic complications of fucoxanthin, specifically, to a pharmaceutical composition for preventing or treating (improving) diabetic complications which includes fucoxanthin derived from sea brown algae such as Eiseniabicyclis, Undariapinnatifida or Hijikiafusiformis as active ingredients, to health supplement, and to insulin sensitive enhancer. The fucoxanthin of the present invention has enhanced inhibition activities of aldose reductase and advanced glycation end-products, and improves insulin resistance by increasing insulin signal transduction through PTP1B suppression activities. Therefore, the fucoxanthin of the present invention can be utilized as a drug such as pharmaceutical composition and health supplement which can prevent or treat the diabetic complications so that the fucoxanthin has greatly high value if applied to food and medicine industries. Especially, the fucoxanthin of the present invention has safety without cytotoxicity as a material derived from natural material so that the composition including the same as the active ingredient can be safe for long term use.
Abstract:
The present invention relates to a novel use of fucosterol to treat degenerative nervous diseases and, specifically, to a pharmaceutical composition and a health functional food including fucosterol as an active ingredient for preventing or treating degenerative nervous diseases. The fucosterol of the present invention can effectively increase the expression of ADAM10 which is α-secretase. Accordingly, the composition of the present invention which includes the same as an active ingredient has an excellent effect in controlling the formation of amyloid beta (Aβ) peptides so that the composition can be usefully used for a pharmaceutical product and a functional food for preventing or treating (alleviating) degenerative nervous diseases. The fucosterol of the present invention is especially a material derived from a natural material so as to have stability without cytotoxicity. Thus, the composition of the present invention which includes the same as an active ingredient is advantageously safe without causing side effects in the human body even after used for a long time.
Abstract:
PURPOSE: A composition having antioxidation activity comprising the extract and flavonoid compounds isolated from Nelumbo nucifera stamen is provided, thereby inhibiting formation of reactive oxygen species(ROS) and inhibiting activity of DPPH radical and lipid peroxide ion, so that it can be useful for prevention and treatment of diseases caused by oxidative stresses. CONSTITUTION: The composition having antioxidation activity comprises a crude extract of Nelumbo nucifera stamen, wherein the crude extract of Nelumbo nucifera stamen is prepared by using a polar solvent selected from water, methanol, butanol or a mixture thereof or a nonpolar solvent selected from ethylacetate, n-hexane, methylene chloride, and chloroform. The composition having antioxidation activity comprises flavonoid compounds isolated from Nelumbo nucifera stamen represented by formula (I), and pharmaceutically acceptable salts thereof, wherein R1 is hydrogen, hydroxy, C1-C4 alkyl or alkoxy, gluco, rhamnogluco(Rha(1>6)-Glu), galacto, glucurono, or lower alkyl glucurono; and R2 and R3 are independently hydrogen, hydroxy, C1-C4 alkyl or alkoxy.
