摘要:Synthesis of enantiopure cis-α-irone from a renewable carbon source Disclosed herein are natural and synthetic enzymes capable of performing a method of producing cis-α-irone. The method comprises providing an enzyme capable of converting psi-ionone to cis-α-irone; and contacting the enzyme and psi-ionone under suitable conditions to produce cis-α-irone. The enzyme may be a methyltransferase from Streptomyces albireticuli (SaMT), a promiscuous bifunctional methyltransferase/cyclase (pMT1) enzyme from Streptomyces, or a modified pMT1 enzyme with at least one substitution. The enzymes allow the in-vivo and in-vitro production of cis-α-irone including the use of glucose as feedstock for the biotransformation into cis-α-irone.

摘要:A cosmetic including two different systems for procurement of actives in the human skin and enhancing the collagen I synthesis. The cosmetic with enhanced collagen I synthesis can include 0.001 to 2% by weight, related to the total weight of the cosmetic, of a first retinol-containing system including retinol encapsulated in a chitosan and carboxymethyl cellulose shell, 0.001 to 3.5% by weight, related to the total weight of the cosmetic, of a second retinol-containing system including cationic liposomes composed of phospholipids and with a quaternary fatty acid monoamine with C 21 -C 23 alkyl residue and the difference to 100% by weight of cosmetic subsidiaries. Very small amounts of retinol in combination with both transport systems show a remarkable effect on the synthesis of collagen I in comparison with one or more other known combinations of retinol derivatives or encapsulated systems.
