Definitions
- the present invention relates to a method for enzyme-catalyzed modification of substances in a mixture, comprising contacting the substance to be modified in a mixture with an enzyme and a substrate.
- the products produced are mixtures of organic substances and can be extracted as such from the reaction mixture.
- Individual substances of these extracts are often isolated due to their better dosability and possible undesirable side effects of the other extract ingredients and e.g. used in cosmetic preparations; see. DE 19615577 AI, JP 11080002 A2.
- the isolated substances are also frequently modified, since it has been shown that the activity of the substance can be increased by the modification.
- arbutin a skin-lightening bearberry glycoside, in the form of its coumaroyl ester is up to 300 times more active than unmodified arbutin; see. EP 0524109 Bl.
- the desired substances can develop their special effect in synergy with the other ingredients of the extracts; see. Lozoya, X., (1997) Spectrum of Science, Special Edition: Pharmaceutical Research, 6, 10-16.
- plant extracts for example, are increasingly being used in the pharmaceutical and cosmetic industries because of the biologically active ingredients they contain, without prior isolation of the desired substances; see. Leung, AN., Foster, S., (1996, 2nd edition) Encyclopedia of common natural ingredients - used in food, drugs, and cosmetics, Verlag John Wiley and Sons, Inc., New York, Brisbane, Singapure.
- enzyme-catalyzed modification or “enzyme-catalyzed modification” used here means that a substance (target substance A) is coupled to a substrate (substance B) in a mixture with the aid of an enzyme as a biocatalyst.
- the invention is illustrated by the following figure.
- Figure 1 is a schematic representation of the effects of salicin and salicine esters on prostaglandin release in keratinocytes. The mean value from three measuring points is shown in each case.
- 1 negative control
- 2 salicin
- 3 phenylpropionyl salicin
- 4 p-OH-phenylacetyl salicin
- 5 positive control.
- One aspect of the present invention relates to a method for enzyme-catalyzed modification of substances in a mixture, comprising contacting the substance to be modified in a mixture with an enzyme and a substrate.
- the biological activity can be increased by enzymatically selective and gentle modification of the substances in mixtures without changing the other ingredients, which are still preserved as valuable substances.
- the biological activity and / or availability is improved and the solubility and / or affinity of the substance (target substance A) is changed.
- the enzyme-catalyzed modification for example by coupling biologically active substrates (substance B), can produce new substances which have additional effects compared to the original substance.
- the target substance A can, for example, by coupling of carboxylic acids can be hydrophobized by means of lipases, can be hydrophilized by coupling sugars / polyols by means of glycosidases or glycosyltransferases, or by coupling of substituted arylaliphati can see carboxylic acids by means of lipases or by coupling of primary amines or peptides by means of transglutaminases or proteases or by coupling of polyols by means of glycosidases Affinity changes glycosyltransferases.
- the mixture can be an extract from plant, animal or microbial cells or can be obtained in biotechnological or chemical production processes.
- a method is preferred in which the plant, animal or microbial cell extract is liquid or dried.
- the modification of the substance can be carried out in such a way that an enzyme is added to the mixture, which reacts the target substance A with a substrate B, so that the desired modified substance A-B is formed.
- the enzyme can be free or immobilized. Immobilized means that the enzyme (biocatalyst) can be ionically or adsorptively coupled to a carrier.
- the carrier can be a hydrophilic or hydrophobic solid particle or a column matrix, the mixture being passed over the column for reaction.

- the enzyme can be immobilized by crosslinking or inclusion in matrices or membranes.
- the enzyme can also be polymer-derivatized.
- the advantage over the chemical modification lies in the high selectivity, the mild conditions and the biocompatibility of the enzyme-catalyzed implementation.
- a glycoside modification by coupling carboxylic acids using conventional chemical synthesis methods is known; see. Colbert, JC, Sugar Esters - Preparation and Application, Noyes Data Corporation, New Yersey (1974).
