J. Slaninova et al., SYNTHESIS AND BIOLOGICAL-ACTIVITY OF 4 VASOPRESSIN ANALOGS MODIFIED IN POSITION 3 WITH BETA-THIENYLALANINE, Collection of Czechoslovak Chemical Communications, 60(4), 1995, pp. 681-686
Four new analogs of arginine-vasopressin substituted in position 3 wit
h beta-thienylalanine were synthesized on chloromethylated resin using
Boc strategy and DCC or DCC-HOBt to form peptide bonds. The activity
of the agonists is not much different in comparison to the unsubstitut
ed compounds. However, the potency of one of the antagonists is strong
ly reduced.
