pressinique acid, its amino acid derivatives substituted and homologs of d configuration, as well as the derivatives (n) - and c - terminal - substituted and their applications in the fields of application, biological or immunological

摘要

The invention relates, as active agents in the therapeutic, biological and immunological fields, and in the field of immunoassays, to pressinic acid, its derivatives which are substituted in at least one of the positions 2, 3, 4 and 5 by natural amino acids and their homologues of D configuration, the acylated derivatives at the N-terminal side of pressinic acid, the amide and ester derivatives at the C-terminal side and the radioactive derivatives of these agents.
