  • Patent number: 6277957
    Abstract: A method is provided which facilitates and enables the production of a wide range of complex conjugates composed of similar or dissimilar units linked together by amide bonds. Said method for the production of acylthio derivatives, R′—CO—SA, involves reaction of a carboxylate, R′—CO—O− (or carboxylic acid R′—CO—OH) with an iso-thiouronium derivative (bearing SA) in the presence of base. Nucleophilic counterion forms of the iso-thiouronium salts confer significant rate enhancement. The processes are simple, generally applicable, efficient, and do not require the employment of noxious reagents. The production of complex protein-like products by the intermediary of acylthio esters generated by the process of this invention, provides a method which is compatible with mild methods of chain assembly; and is preferably applied when the second component in the ligation bears an amino terminal cysteine residue.

  • Patent number: 5705671
    Abstract: The present invention provides a simple and inexpensive method for producing .alpha.-hydroxy-.beta.-aminocarboxylic acids and their esters. An ester of an N-protected .alpha.-amino acid ester is converted into a .beta.-ketosulfoxide, which is then processed with an acid to give an .alpha.-ketohemimercaptal. Next, this is acylated and then processed with a base to obtain an N-protected .alpha.-acyloxy-.beta.-amino-thioester, which is then saponified to obtain an intended compound. According to the method of the present invention, it is possible to produce .alpha.-hydroxy-.beta.-aminocarboxylic acid derivatives, which are intermediates in producing various HIV protease inhibitors, renin inhibitors and carcinostatics, from a-amino acids. The method comprises reduced reaction steps, the selectivity in the method to give the intended product is high, and the yield of the product obtained is high.

  • Patent number: 5470997
    Abstract: The present invention is directed to novel amphetamine derivatives which are synthesized for the covalent attachment to antigens (proteins or polypeptides) for the preparation of antibodies or receptors to amphetamine and amphetamine metabolites. The resulting novel antigens may be used for the production of antibodies or receptors using standard methods. Once generated, the antibodies or receptors and the novel derivatives which are covalently attached to proteins, polypeptides or labels may be used in the immunoassay process.
