(Z) tripeptideinhibitors of angiotensin-convertingenzyme (ACE) was synthesized. The effect of varying the antepenultimate amino acid residue in this series on the biologicalactivity was studied. Introduction of Lys and Orn residues at the P1 position provided the most potent inhibitors, 25a and 25b (IC50: 3.5 and 4.9 x 10(-9) M, respectively), which exhibited an oral antihypertensive activity. This
合成了一系列新的含γ-D-Glu的血管紧张素转化酶(ACE)的N-苄氧基羰基(Z)三肽抑制剂。研究了改变该系列中前倒数第二个氨基酸残基对生物活性的影响。在P1位置引入Lys和Orn残基可提供最有效的抑制剂25a和25b(IC50:分别为3.5和4.9 x 10(-9)M),具有口服降压活性。该结果表明,在该系列中,P1位的碱性氨基酸残基在与ACE的S1亚位点的结合中起重要作用。评价了所选化合物的口服降压活性。

Analogues of (S)-1-[6-amino-2[[hydroxy(4-phenylbutyl)phosphinyl] oxy]-1-oxohexyl]-L-proline (1, SQ 29,852) in which the terminal proline residue has been replaced by a variety of substituted and heteroatom-substituted prolines, N-arylglycines, N-cycloalkylglycines, and bicyclic amino acids have been synthesized and evaluated as inhibitors of angiotensin converting enzyme in vitro and in vivo. In general, the addition of lipophilic substituents to the 4-position of proline of the parent phosphonate 1 resulted in substantial increases in in vitro activity. The largest improvements were observed in the case of cis-benzyl (36-fold) and dithioketal (24-fold) analogues 2r and 2x, respectively. These enhancements of in vitro activity were accompanied by modest increases (2-3.5-fold) in in vivo (iv) activity. Among the various terminal amino acid replacements examined in this study, the indoline-based analogue 2i was by far the most potent compound on iv administration in the normotensive rat.
