摘要: Analogues of 8-D-homoarginine vasopressin were prepared with the general formula ##STR1## where X is L-O-methyltyrosine, L-p-ethylphenylalanine, D-p-ethylphenylalanine, L-p-methylphenylalanine or D-methylphenylalanine and R is cysteine or .beta.-mercaptopropionic acid. These vasopressin analogues exhibited an increased affinity to uterus receptors for oxytocin, where they acted as ocytocin antagonists. Moreover, the analogues of deamino vasopressin have a significantly reduced antidiuretic activity in comparison with [8-D-arginine]vasopressin.
