New Macrocyclic Derivatives Containing Chiral and Linear Lateral Amino-Acid Moieties
摘要:
We report the preparation of a new series of functionalized derivatives of dibenzo-18-crown-6, containing in second sphere of coordination lateral arms of different Linear and chiral L-amino acids: glycine, beta-alanine, 11-aminoundecanoic acid, L-cysteine, L-aspartic acid, L-phenylalanine, L-tryptophan, L-histidine. All these new derivatives were characterized by elemental analysis, LR and H-1-NMR spectroscopy, and these data were in agreement with proposed molecular structures.

The present patent application relates to a cosmetic or dermatological composition comprising, in a cosmetically or dermatologically acceptable medium, a polymer comprising:
(a) a polymer backbone that may be obtained by reaction:
of a polyol comprising 3 to 6 hydroxyl groups;
of a monocarboxylic acid containing 6 to 32 carbon atoms;
of a polycarboxylic acid comprising at least two carboxylic groups COOH, and/or of a cyclic anhydride such as a polycarboxylic acid and/or of a lactone comprising at least one carboxylic group COOH; and
(b) at least one junction group linked to the said polymer backbone and capable of establishing H bonds with one or more partner junction groups, each pairing of a junction group involving at least three H (hydrogen) bonds.
The patent application also concerns a cosmetic treatment process using the said composition.

The present application relates to a cosmetic or pharmaceutical composition comprising a polycondensate capable of being obtained by the reaction of the following monomers alone:
of 10 to 30% by weight, relative to the total weight of the polycondensate, of one or more polyols comprising 3 to 6 hydroxyl groups;
of 30 to 80% by weight, relative to the total weight of the polycondensate, of one or more linear, branched and/or cyclic, saturated or unsaturated, non-aromatic monocarboxylic acids comprising 6 to 32 carbon atoms;
of 1 to 40% by weight, relative to the total weight of the polycondensate, of one or more polycarboxylic acids and/or cyclic anhydrides of such a polycarboxylic acid and/or lactones comprising at least one COOH group;
and optionally of 0.1 to 15% by weight, relative to the total weight of the polycondensate, of one or more silicones having a hydroxyl and/or carboxyl functional group.
The application also relates to a method of cosmetic treatment using the said composition, and the polycondensate thus defined.
