| 560170000 | Oxy, aldehyde or ketone group in acid moiety | 10 |
| 20080319221 | Esters of Pentahydroxyhexylcarbamoyl Alkanoic Acids - Provided are compounds of formula A and formula I: A compound of formula A: | 12-25-2008 |
| 20100022795 | Process for producing optically active beta-hydroxy-alpha-aminocarboxylic acid ester - It is an objective of the present invention to produce an anti-form of an optically active β-hydroxy-α-aminocarboxylic acid ester efficiently, simply and industrially advantageously. The objective can be accomplished by directly and selectively producing the anti-form of the optically active β-hydroxy-α-aminocarboxylic acid ester by asymmetric reduction of a β-keto-α-aminocarboxylic acid ester using an optically active amine complex as a catalyst. Further, the β-keto-α-aminocarboxylic acid ester as a raw material can be produced at a high yield by reacting a glycine derivative with a carboxylic acid derivative. | 01-28-2010 |
| 20120316359 | Biological Buffers with Wide Buffering Ranges - Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability. | 12-13-2012 |
| 20130096340 | AMINO ACID GROUP-MODIFIED ORGANOPOLYSILOXANE AND SILANE, AMINO ACID GROUP-CONTAINING COMPOUND, AND PRODUCTION METHOD THEREOF - An amino acid-modified organopolysiloxane is provided. It has an amino acid derivative bonded to at least one silicon atom of the organopolysiloxane segment constituting the backbone of the organopolysiloxane via an amide bond represented by the following general formula (1): | 04-18-2013 |
| 20130217913 | Antimalarial Drug Comprising Alaremycin or Derivative Thereof as Active Ingredient - Provided is a preventive and/or therapeutic agent for malaria, comprising, as an active ingredient, 5-acetamido-4-oxo-5-hexenoic acid (Alaremycin) or a derivative thereof. A preventive and/or therapeutic agent for malaria is used which comprises, as an active ingredient, Alaremycin or a derivative thereof represented by formula (I) (wherein R | 08-22-2013 |
| 20130303799 | PROCESS FOR THE PREPARATION OF POLY(ALKYLENE OXIDE) DERIVATIVES FOR MODIFICATION OF BIOLOGICALLY ACTIVE MOLECULES AND MATERIALS - A a method for producing activated linear polymers and activatable branched polymers thereof, is carried out by a) reacting a linear nonpeptidic activatable polymer, chemically blocked at one end, with an azole ring activating group that provides a leaving group to produce an intermediate polymer of the general formula poly-lm; b) reacting said poly-lm with an alkylating agent to form an imidazolium salt of the general formula poly-1m+(alkyl)X-; and c) reacting said poly-lm +(alkyl)X with a linker molecule bearing at least two nucleophilic moieties to produce an activatable branched polymer derivative thereof. In some embodiments “poly” is a polymer selected from the group consisting of poly(alkylene oxides), poly(oxyethylated polyols), poly(olefinic alcohols), and polymers of alkylene oxide and propylene oxide; in some embodiments “Im +” is an imidazolium ion; and in some embodiments “X-” is an anionic counterion. | 11-14-2013 |
| 20140187810 | STABILIZED COMPOSITIONS OF ALKYLATING AGENTS AND METHODS OF USING SAME - Provided are stable compositions comprising alkylating agents, including nitrogen mustards, that are suitable for topical use, and methods for treating skin disorders comprising topically administering the compositions. | 07-03-2014 |
| 20140296562 | METHOD FOR PRODUCING OPTICALLY ACTIVE BETA-HYDROXY-ALPHA-AMINOCARBOXYLIC ACID ESTER - The present invention relates to a novel method for producing an optically active β-hydroxy-α-aminocarboxylic acid ester, the method comprising performing an asymmetric reduction reaction of a β-keto-α-aminocarboxylic acid ester by use of a ruthenium complex as a catalyst. | 10-02-2014 |
| 20150353474 | CARBOXYBETAINE-FUNCTIONALIZED DIOLS - A compound having the formula: X | 12-10-2015 |
| 20160017389 | METHOD FOR PREPARING (2RS)-AMINO-(3S)-HYDROXY-BUTYRIC ACID AND ITS DERIVATIVES - The present invention relates to a method for easily preparing (2RS)-amino-(3S)-hydroxy-butyric acid, which is a chiral amino acid, in a high yield and a high purity using a chemical synthesis and enzymatic reduction reaction; an intermediate therefor; and a method for preparing the intermediate. | 01-21-2016 |
