How to Prepare Calcium Alpha-Ketovaline and Its Applications?Background and Overview[1][2] Calcium alpha-ketovaline is one of the main components of the compound α-keto acid tablets (Kaitong). α-Keto acids and their derivatives have shown increasing.....
Salts of keto acids and amine derivatives and their use for the preparation of medicaments. The invention concerns the use of compounds of general formula (I): (X)n1,Y,(Z)n2 wherein n1 and n2 represent 0 or 1; X represents a natural amino acid, in... T Bouyssou,S Biosa,PA Settemb...
hydroxytetradecanoic acid and positional isomers of dihydroxyhexadecanoic acid (Goni MA et al., Geochim Cosmochim Acta 1990, 54, 3073). The hydroxylated fatty acids from leaf-derived lipids have been proposed as plant biomarkers in soils and sediments (Mueller KE et al., Org Geochem 2012, 52,...
Although it is known that reduced derivatives of KAs including methylglyoxal are highly reactive to form advanced glycation endproducts (AGEs), the reactivity of KAs to form products similar to advanced glycation endproducts (SAGEs) remains unclear. Herein, we evaluated four keto acids including ...
ChemInform Abstract: Derivatization of Keto Fatty Acids. Part 9. Synthesis and Characterization of Oxathiolanesoxathiole derivativesOxo fatty acids such as (Ia) and (Ib) react with 2-mercaptoethanol (II) in the presence of boron trifluoride etherate to give the long-chain substituted oxathiolanes ...
2. 2. Collagen was digested in the native state by pronase, and the high molecular weight protein fractions were removed by dialysis or precipitation. Carbonyl-containing components (including α-keto acids) in the diffusate or supernatant were assayed as DNP-hydrazone derivatives. 3. 3. Very ...
Acetylene derivatives of amino acids Novel compounds of the following general formula are useful pharmacologic agents: ##STR1## R is selected from hydrogen, alkylcarbonyl wherein the alkyl moiety contains from 1 to 4 carbon atoms, alkoxycarbonyl wherein the alkoxy moiety co... BW Metcalf,M Jun...
An object of the present invention is to provide a method for synthesis of keto acids by hydration of an acetylene compound (acetylene-carboxylic acids) under mild conditions free from harmful mercury catalysts and a method for synthesis of amino acids from acetylene-carboxylic acids in a single ...
Some new 脦虏-ketoester derivatives of aluminium having the general formula (OPr1)3-nAl[(R)CHCOCOOMe]n (where n = 1, 2 and 3; R = C6H5, p-BrC6H4 and p-BrC6H4) have been synthesised by the reactions of the methyl esters of aroyl pyruvic acids (aroyl = benzoyl, p-chlorobenzoyl...
