4 results about "Acylglycine" patented technology

The present disclosure relates to analytical LC-MS / MS methods for second tier testing in Newborn Screening Program (2ndtier test or 2TT) for the simultaneous measuring of organic acids, acylcarnitines, aminoacids derivatives and acylglicines in dried blood spot samples.

Disclosed is a cosmetic composition comprising i) glycine; and ii) an N-acyl glycine containing an acyl group of 11 carbon atoms; wherein the weight ratio of the glycine to the N-acyl glycine is from 1:10 to 30:1; wherein the composition is substantially free of titanium dioxide.

Disclosed are methods and uses for inhibiting protease activity, thereby preventing or reducing hair loss, comprising applying capryloyl glycine or a composition comprising capryloyl glycine to the scalp of an individual.

The application discloses a method for preparing dibutyl lauroyl glutamine and application, wherein long-chain alkyl acyl glycine and acetic anhydride are added into a first reaction container containing cyclohexane, a long-chain alkyl cyclization product is prepared by warming and refluxing reaction; the prepared long-chain alkyl cyclization product is added into a second reaction container containing cyclohexane, an alkaline substance and N-butyl acrylamide are further added for reaction, the alkaline substance and solvent are removed after the reaction, and a long-chain alkyl butylamide propenyl oxazolone is prepared; the prepared long-chain alkyl butylamide propenyl oxazolone is put into a third reaction container containing cyclohexane, n-butylamine is further added into the third reaction container for refluxing reaction, and the solvent is evaporated to prepare long-chain alkyl glutamic acid dibutylamide. The application firstly performs ring-closing reaction, then performs Michael addition on a reserved site of the structure, and ingeniously performs chain extension reaction on the structure, and finally obtains a target compound.
