  • Publication number: 20140323756
    Abstract: The present invention is related to synthesis of highly pure cationic surfactant products by eliminating or reducing impurities generation that has beset prior art. This is achieved through the N-acylation of ester of amino acid and its inorganic salts or its organic salts (e.g. amino acid or hydrochloride of amino acid or sulfate of amino acid or acetate of amino acid etc.) in non-hydrolytic or nearly non-hydrolytic reaction conditions involving mono or biphasic reaction system with fatty acid halide (C4 to C20), under moderate uniform basic condition yielding high purity N-acyl substituted amino acid ester, particularly ethyl lauroyl arginate. The present process achieves pH control through process strategy rather than the measurement and control steps. This ambient temperature process is stable through a range of temperature variation eliminating rigid low temperature control.

    Abstract: This invention relates to a use of a composition for protecting oral cavity and teeth containing ethyl-N?-lauroyl-L-arginate HCl (LAE), a corresponding composition and a corresponding method for protecting teeth. Because of nearly epidemic incidence of dental erosion, there is a continuing need for improved products that provide protection against dental erosion. Hence, it is an object of the present invention to protect teeth against dental erosion. Surprisingly, it has been found that ethyl-N?-lauroyl-L-arginate HCl (LAE) and its salts attach to teeth and provide protection of teeth from erosion especially caused by the action of acid in food products and drinks such as chewing gum and lozenges compositions. Special advantages of this invention are: (a) sustained coating of the teeth by LAE and its homologues; (b) the coating agent provides a source of neutralizing plaque acids by providing sustained base formation.

  • Patent number: 6784311
    Abstract: Process for the preparation of 3-aminoalkanoic acid esters of the general formula: in which R is C1-6-alkyl and R1 is hydrogen, C1-6-alkyl or phenyl, or their salts, by catalytic hydrogenation of the corresponding 3-amino-2-alkenoic acid esters of the general formula: in which R and R1 have the above mentioned meanings. The hydrogenation is carried out in the presence of a strong acid and the salt of the 3-aminoalkanoic acid ester (I) and the strong acid formed is optionally converted into the free 3-aminoalkanoic acid ester (I) or into another salt in a manner known per se.

  • Publication number: 20040024224
    Abstract: Non-natural amino acids such as 2-alkylated amino acids allow for the synthesis of a wider variety of peptidal and non-peptidal pharmaceutically active agents. A method of preparing a 2-alkyl amino acid involves a Michael-type addition of a nucleophile to a dialkyl 2-methylidenylpropan-1,3-dioate and the conversion of a ester moiety into an amino moiety. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.

  • Publication number: 20030060653
    Abstract: The invention relates to N-unsubstituted imidic ester alkyl sulphates, N-unsubstituted amidinium alkyl sulphates and a process for their preparation, which is characterized in that carboxamides are converted with sulphuric diesters into the corresponding imidic ester alkyl sulphates, which are reacted further with ammonia to give the analogous amidinium alkyl sulphates.

  • Publication number: 20030013657
    Abstract: Certain known and novel pyruvate derivatives are particularly active in restoring or preserving metabolic integrity in oxidatively competent cells that have been subjected to oxygen deprivation. These pyruvate-derived compounds include, but are not limited to oximes, amides, pyruvate analogues, modified pyruvate analogues, esters of pyruvate (e.g., polyol-pyruvate esters, pyruvate thioesters, glycerol-pyruvate esters and dihydroxyacetone-pyruvate esters). Such pyruvate derivatives (including single tautomers, single stereoisomers and mixtures of tautomers and/or stereoisomers, and the pharmaceutically acceptable salts thereof) are useful in the manufacture of pharmaceutical compositions for treating a number of conditions characterized by oxidative stress.
