Abstract
New pentapeptides having the formula X-R-His(benzyl)-His(benzyl)-R.sup.1 -Trp-R.sup.2 -Y wherein X is t-butoxycarbonyl or benzyloxycarbonyl, R is a single bond or Pro; R.sup.1 is Ser(benzyl) or Tyr(benzyl), R.sup.2 is a single bond or Ala and Y is lower alkoxy, amino, lower alkylamino or di(lower alkyl)amino with the proviso that the total number of amino acid units when R and R.sup.2 are combined is one.
