Novel N-(N-Pg-azadipeptidoyl)benzotriazoles 20a-e couple efficiently with α-amino acids 21a-e, dipeptides 22a-c, aminoxyacetic acid 23a, depsidipeptide 23b, and α-hydroxy-β-phenylpropionic acid 27 yielding, respectively, azatripeptides 24a-g, azatetrapeptides 25a,b, a hybrid azatripeptide with an oxyamide bond 26a, a hybrid azatetrapeptide with an ester bond 26b, and a hybrid azatripeptide with an ester bond 28. A new protocol for the synthesis of N-Pg-azatripeptides 33a,b and 35a,b, each containing a natural amino acid at the N-terminus, avoids the low coupling rates of the aza-amino acid residue and enables the solution-phase synthesis of an azaphenylalanine analogue of Leu-enkephalin 40.
Synthesis and biological evaluation of phosphonamidate peptide inhibitors of enkephalinase and angiotensin-converting enzyme

The effectiveness of phosphonamidate peptide analogues as inhibitors of rat kidney or human brain metallo-endopeptidase (enkephalinase, E.C. 3.4.24.11) and angiotensin-converting enzyme (ACE, 3.4.15.1) has been explored with a series of enkephalin analogu
Luteinizing hormone releasing hormone and analogs. Synthesis and biological activity

A fragment synthesis of LH RH is described which lends itself to large scale preparation. Fragment 1-3 is coupled with fragment 4-6 followed by reaction with the tetrapeptide 7-10 to yield the unprotected decapeptide. The preparation of analogs follows the same synthetic pattern. The biological activity of the analogs is compared with that of synthetic LH RH.
