preparation example 1

[0053] Preparation Example 1: Small Molecule Fucoidose

[0054] The extraction method of this experiment is to put 100 g of dry algae into 5 liters of distilled water and boil them in boiling water at 100°C for 30 minutes, then centrifuge the hot water extract, and freeze the supernatant under reduced pressure. After drying (lyophilized), 95% ethanol was added and left standing at 4°C overnight to obtain a precipitate. The precipitated polysaccharides were further collected by centrifugation, and then lyophilized to obtain the primary extract of algae. Finally, the primary extract of algae is further hydrolyzed with enzymes to obtain low-molecular-weight fucoidose, and the low-molecular-weight fucoidose contains a hetero-oligosaccharide, and the average molecular weight of the hetero-oligosaccharide is 400 Daltons to 1500 Daltons pause. The fucoidose used in this experiment was low molecular weight fucoidan produced by Taiwan Chunghwa Marine Biotechnology Co., Ltd., and it w...

[0055] Preparation Example 2: Fucoidose L-Amino Acid Complex

[0056] The small molecule fucoidose and L-arginine were mixed in a weight ratio of 1 to 1, 1 to 2.5 and 1 to 5, respectively, and after stirring at 300 rpm for about 12 hours, the molecular weight cutoff (MWCO) 1000 Dalton (Da) (ie, 1000 MWCO) cellulose dialysis membrane was purified in deionized water for 1 day, and then freeze-dried to obtain a fucoidose L-amino acid complex.

preparation example 3

[0057] Preparation Example 3: Fluorescent Complex

[0058] (1) Fucoidose Fluorescent Complex: Mix 1 mmol (mmol) of small molecule fucose, 3 mmol of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (1-ethylaminopropyl) -3-(3-dimethylaminopropyl)-carbodiimide (EDC) and 4 mmol of N-Hydroxysuccinimide (NHS) in 10 mL of dichloromethane (DCM) solvent and stirred for 12 hours , so that NHS and the carboxyl group (C(=O)OH)) of the small molecule fucose are bonded to form an ester group. After that, 8 mmol of ethylenediamine (EDA) and 200 μL of pyridine (pyridine) were added, and stirred for 24 hours to aminate the small molecule fucose, and then purified in deionized water with a 1000 MWCO dialysis bag for 2 days, and frozen. After drying, an aminated small molecule fucose is obtained. Mix 18 mmol of aminated small molecule fucose and 0.2 mmol of Cy3 NHS ester dye (Cyanine 3(Cy3) NHS ester dye, purchased from Hallandale Beach, USA) dissolved in 10 mL of DCM, and stir for 24 hours, and ...

The fucose amino acid compound disclosed by the invention can be used for improving the cell internalization degree of micromolecular fucose. The invention further provides pharmaceutical application of the fucose amino acid compound, health food containing the fucose amino acid compound, cosmetics containing the fucose amino acid compound and a fucose amino acid medicine compound containing the fucose amino acid compound.

Description

technical field [0001] The present invention relates to a fucose amino acid complex, especially a fucose amino acid complex comprising small molecules of fucose and L-arginine. Background technique [0002] Brown algae is a common ingredient in daily diet, including: kelp, wakame or kelp, etc., and is rich in vitamins and minerals, and is most notable for its Fucoidan. The structure of fucoidan is mainly based on fucose, so it is also called fucoidan. It is widely used in medicine, biomedicine, cosmetics because of its anti-oxidation, anti-inflammatory, and immunity-enhancing functions. and food. [0003] However, the average molecular weight of fucoidan is about 20kDa, which limits its cellular internalization. Therefore, how to improve its cellular internalization degree to effectively exert its activity is a problem to be solved. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the present invention provides a fucoidan amino acid complex, which ...
