## Abstract Twelve analogues were synthesized, their structure derived from modifications of [(S)Pmp^1^, DβTrp^2^, Pen^6^, Arg^8^]oxytocin, PA, in which (S)Pmp = Ξ²,Ξ²β(3βthiapentamethyleneβΞ²βmercaptopropionic acid). PA is a potent antagonist of the uterotonic effect of oxytocin in the rat (uterotoni
Two-and four-cell mouse embryos exhibited both Na+dependent and Na+-independent components of zwitterionic a-amino acid transport, which we tentatively ascribe to the A and L amino acid transport systems, respectively. Uptake of taurine was virtually all Na f -dependent and is probably via the / 3 s
