  • Novel analogs of deamino-vasopressin with a modified disulfide bridge and manufacturing process thereof
    Patent number: 3980631
    Abstract: Stepwise synthesis in solution and cyclization by means of active esters or another method suitable for peptide bond formation were used to prepare analogues of deamino-vasopressin with the disulphide bridge altered to the thioether group. In sequence position 8 of the peptide chain the analogs differed by the nature of basic amino acid. Typical vasopressin-like activities, mainly antidiuretic, were very high in these analogs; of particular importance will be their haemodynamic activity.
