摘要: Abstract Two constrained analogs of the tripeptide hormone thyroliberin (TRH) have been synthesized. In both, HisPro peptide bond has ‘locked’ into a cis -conformation. first analog, constraint used was identical to in an earlier trans -peptide analog that potent agonist for TRH endocrine receptor TRH-R 1 . The second built order take advantage tetrazole ring as constraint. Neither showed or antagonist behavior toward suggesting conformation may not play role affinity
