- Lysine hydrochloride (78.62 g; 0.430 mol) and 200 ml of distilled water were added to a 500 ml reaction vessel, and the mixture was stirred vigorously under ice cooling. Next, sodium hydroxide aqueous solution
- the aqueous layer was separated, neutralized to pH 7.0 with an aqueous sodium hydroxide solution, added with paramethoxyphenol (about 50 mg) and normal butanol (about 150 ml), and concentrated under reduced pressure until the remaining amount was about 270 g. . Further, 1.4 L of isopropanol was added, and the mixture was vigorously stirred for about 90 minutes, and then allowed to stand at 5 ° C for about 90 minutes. An insoluble substance was deposited, but this was filtered off and the filtrate was subjected to paramethoxyphenol.
- hydrochloride of compound represented by formula (5) and compound represented by formula (6) In a 500 ml reaction vessel, lysine hydrochloride (78.62 g; 0.430 mol) and 200 ml of distilled water were added. The mixture was stirred vigorously under ice cooling. Subsequently, the pH was adjusted to 8.0 by adding a small amount of an aqueous sodium hydroxide solution (about 50 wt / v%). Further, with vigorous stirring, simultaneously add methyl methacrylate chloride (37.50 g; 0.359 mol) and an aqueous sodium hydroxide solution in about 15 minutes while adjusting the inside of the reaction vessel to pH 8.0. It was dropped.
- Example 12 Production of Fluorescent Labeled Polymer
- Each of the polymers prepared in Examples 1 to 6 was labeled with a dansyl group having fluorescence.
- a fluorescently labeled polymer is produced by adding the dansyl group-introduced compound represented by the formula (20) to a monomer of the original polymer at a ratio of about 1/50, followed by polymerization. did. Equation (20)
- Ethyltrimethylammonium chloride-methacrylic acid ester (4.15 g) was dissolved in 3 Oml of water, 0.167 g of a fluorescently labeled monomer dissolved in 30 ml of methanol was added, and nitrogen gas was bubbled for 1 hour. To this was added 0.050 g of potassium persulfate to dissolve, and the mixture was heated and refluxed for 3 hours while passing nitrogen gas. The reaction was poured into isopropanol, causing a precipitate to form. The supernatant was removed by decantation, and acetone was added to the precipitate, followed by vigorous stirring. The resulting precipitate (powder) was collected by filtration, washed with acetone, and dried to obtain the target polymer. Production Example 7
- the exfoliated skin (2 Omm x 20 mm) of the back exfoliated skin of a hairless mouse (male, weighing 25-30 g) was treated with dispase. This was treated with trypsin in 0.25% phosphate buffer at 37 ° (: 1 hour, the horny layer was collected, a 1 Omm x 10 mm horny layer was stuck on a slide glass for fluorescence microscopy, and air-dried for 24 hours. did.
- mice Male, body weight
- 0.1 ml of 3035% aqueous solution once a day for 3 days
- apparent adsorption strength refers to the degree to which the polymer is adsorbed on the skin. Also, the “apparent adsorption strength” mentioned here was regarded as the sum of the two types of adsorptivity. They are,
- adheresion strength Physical adsorbability of the polymer itself (here the factory called “adhesion strength”)
- Adhesive strength (Ao) Adhesive strength (Ao)
- the fluorescence intensity of the slide glass was calculated (blank, AB). Further, a slide glass was coated with 1 of a 5 wt% / 30% aqueous ethanol solution of each fluorescently labeled polymer, and then air-dried for 30 minutes. It was immersed again in 50 ml of water for 10 minutes, then air-dried for 30 minutes, and the fluorescence intensity was measured (AH; Ex 331 nm, Em 505 nm).
- Label 1 alanine-amide methacrylate 'polymer
- Label 2 Glucamine-methacrylic acid amide 'polymer
- Label 3 Lysine-methacrylic acid amide polymer
- Label 4 Aranine-methacrylic acid amide: Arginine-methacrylic acid amide
- Label 5 Ethyltrimethylammonium chloride-methacrylate ether polymer It can be seen that the polymer has a stronger chemical affinity for damaged skin such as SDS-treated horny layer and UV-damaged skin than for untreated horny layer. That is, a group having an affinity for an amino group and / or a group having an affinity for a carboxyl group characteristically possessed by the polymer has a stronger chemical affinity with a disordered portion of the skin structure, and repairs the structure. You can see that it is.
- the constituent monomer content of the compound represented by the formula (22) in the product is determined. That is, the copolymer obtained in Example 26 quantitatively contains a labeling group by containing the compound represented by the formula (22) as a constituent monomer. It is quantitatively labeled and its behavior can be known quantitatively.
- Table 9 shows that the amount of adsorption to the SDS-treated stratum corneum and the UV-damaged stratum corneum was larger than that of the untreated stratum corneum.
- the SDS-treated stratum corneum and the ultraviolet ray-damaged stratum corneum have greater disorder and destruction of the structure of peptides, collagen, and keratin.
- the group has an affinity and adsorption with the amino acid residue in the side chain of the copolymer obtained in Example 12. . That is, by using the copolymer obtained in Example 12, it became possible to identify groups having an affinity for amino acid residues such as a free amino group and a free carboxyl group.
- Example 14 Evaluation of Adsorption of Hair to Hair Using the fluorescent-labeled polymer prepared in the above Example, the adsorption of the polymer to hair was evaluated. Keratin derived from human hair was used as a hair model for evaluation. Powder was used.
- the amino acid of the present invention It can be seen that the pendant polymer has a protective or improving effect not only on damaged skin but also on damaged hair.
- a group having an affinity for an amino group and / or a group having an affinity for a lipoxyl group characteristically of the polymer has a stronger chemical affinity to a disordered portion of the hair structure, and the structure thereof is changed. You can see that it has been repaired.
- INDUSTRIAL APPLICABILITY According to the present invention, a polymer having an action suitable for skin function can be provided.
- a topical skin containing a polymer having a group having affinity for the skin in a part thereof, and a polymer exhibiting a suitable action on the skin function by the skin-friendly group. Can be provided.
