Embodiment 1

[0092] Example 1: Preparation of Red Bean Extract and Fractions and Compounds of Chemical Formulas 1 and 2 separation and purification of

Embodiment 1-1

[0093] Example 1-1: Preparation of red bean extract

[0094] Wash red beans (red beans or adzuki beans) with water, dry them in a cool place, and grind them into powder using a Waring blender. Add 20 kg of powdered red beans to 100 L of methanol, cold soak and extract for 3 days, filter under reduced pressure with filter paper (Waterman Company, USA), and then use a vacuum rotary concentrator to filter the extract to The methanol solution was removed to obtain 450 g of extraction residue, which is the red bean extract.

Embodiment 1-2

[0095] Example 1-2: Preparation of Fractions

[0096] In order to separate the active fraction from the red bean extract prepared above, after the red bean extract was suspended in 1L of water, an equal amount of n-hexane was added, mixed and graded, and this process was repeated 4 times to obtain 1L of water-soluble Fraction and 4 L of n-hexane soluble fraction.

[0097] Next, the n-hexane-soluble fraction was concentrated under reduced pressure to obtain 50 g of n-hexane-soluble extract.

[0098] In addition, an equal amount of ethyl acetate was added to the 1L water-soluble fraction, mixed and classified, and this process was repeated 3 times, thereby re-obtaining 1L of water-soluble fraction and 3L of ethyl acetate-soluble fraction.

[0099] The obtained ethyl acetate soluble fraction was concentrated under reduced pressure to obtain 35 g of ethyl acetate soluble extract. The remaining water-soluble fraction was concentrated under reduced pressure to 35 g, which was us...

Abstract

The present invention relates to a pharmaceutical composition for preventing or treating TLR- or IL-6-mediated diseases, containing oleanolic acid acetate or pharmaceutically acceptable salts thereof as an active ingredient, and to a pharmaceutical composition for preventing or treating TLR- or IL-6-mediated diseases and containing phaseoli semen extract, or a fraction thereof, which contains said compound or salts as an active ingredient. The phaseoli semen extract or compound according to the present invention is derived from a natural substance, which has long been used in natural medicine, and therefore causes no side effects. The phaseoli semen extract or compound inhibits the activity of TLR-3 and TLR-7 induced by Poly(I:C) and Poly(I), which are the synthetic analogues of dsRNA and ssRNA, blocks signaling pathways including NF-kappaB, and inhibits the transcriptional activity and phosphorylation of STAT3, which is an inflammation-related transcription factor activated by IL-6. Therefore, the phaseoli semen extract or compound of the present invention can be widely used in developing agents for preventing or treating TLR- and IL-6-mediated diseases, such as atopic dermatitis or arthritis.

Description

technical field [0001] The present invention relates to a pharmaceutical composition for preventing or treating TLR and IL-6-mediated diseases comprising oleanolic acid acetate as an active ingredient, more specifically, comprising oleanolic acid acetate or its Pharmaceutical composition for preventing or treating diseases mediated by TLR and IL-6, with medicinal salt as active ingredient; prevention or treatment containing red bean extract or fraction thereof containing said compound or its salt as active ingredient A pharmaceutical composition for a TLR and IL-6 mediated disease; and a method for treating a TLR and IL-6 mediated disease comprising the step of administering the composition to an individual suspected of having a TLR and IL-6 mediated disease. Furthermore, the present invention also relates to skin external preparations, health functional foods and personal hygiene products for preventing or improving TLR and IL-6-mediated diseases, which contain the active ing...
