标题 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives

摘要:Methods for the synthesis of alpha-hydroxy-beta-amino acid and amide derivatives and alpha-ketoamide derivatives and novel derivatives made by these methods are provided. These methods involve reacting a N-terminally blocked (protected) aminoaldehyde with an isonitrile and a carboxylic acid to give an amino-alpha-acyloxy carboxamide. The acyloxy group may be removed to give the derivative. Alternatively the protecting group is removed and acyl shift occurs to give the derivative. These derivatives are useful in the synthesis of compounds such as peptidyl alpha-ketoamides and alpha-hydroxy-beta-carboxylic acid and amide derivatives. Certain of these compounds have been reported to have activity as inhibitors of proteases, such as serine proteases and cysteine proteases.

摘要:The present invention relates to the synthesis of peptide-oligonucleotide conjugates (POC). More specifically, the invention relates to a novel method for the preparation of peptide-oligonucleotide conjugates, which can be conducted under mild conditions on solid support, can be performed manually or by a synthesizer, can be used to synthesize alternating sequences of peptides and oligonucleotides, and is applicable to the synthesis of a wide variety of peptide-oligonucleotide conjugates constructed from alternate peptide and oligonucleotide blocks.

摘要:Novel compounds represented by the following formula: ##STR1## wherein A represents a specific amino acid residue are excellent as substrates for determination of enzyme activity such as trypsin, etc. The compounds can be synthesized from novel arginyl-3-tert-alkyloxycarbonyl-4-nitroanilides by a novel process comprising a selective deprotection step whereby the protecting group on the α-amine group of arginine is removed in the presence of a hydrochloric acid, acetic acid and dimethylformamide mixture, but a tert-alkyl protecting group on the --COOH group of the nitroanilide ring is not removed by this step.
