  Design, structure-activity, and molecular modeling studies of potent renin inhibitory peptides having N-terminal Nin-For-Trp (Ftr): angiotensinogen congeners modified by P1-P1' Phe-Phe, Sta, Leu.psi.[CH(OH)CH2]Val or Leu.psi.[CH2NH]Val substitutions

  摘要：

  A structure-conformation-activity investigation of several angiotensinogen (ANG) based inhibitors of human renin modified by either Phe-Phe, Sta, Leu psi[CH2NH]Val, or Leu psi[CH(OH)CH2]Val at the P1-P1' clevage site and P5 Trp(Nin-For) (Ftr) was performed. Specifically, Ac-Ftr-Pro-Phe-His-Phe-Phe-Val-Ftr-NH2 (1) provided a potent (KI = 2.7 X 10(-8) M) P1-P1' Phe-Phe substituted renin inhibitor to initiate these studies. Substitution of the P1-P1' Phe-Phe in compound 1 by Sta effected a 1,000-fold increase in biological potency for the resultant octapeptide Ac-Ftr-Pro-Phe-His-Sta-Val-Ftr-NH2 (10; KI = 6.7 X 10(-11) M). Kinetic analysis of compound 10 showed it to be a competitive inhibitor of human renin catalyzed proteolysis of human ANG. Chemical modifications of the compounds 1 and 10 were evaluated on the basis of comparative human plasma renin inhibitory activities (IC50 values) in vitro. Carboxy-terminal truncation studies on compound 10 showed that the P2' Val and P3' Ftr residues could both be eliminated without significant loss (ca. 10-fold) in renin inhibitory activity as exemplified by the pentapeptide Ac-Ftr-Pro-Phe-His-Sta-NH2 (12; IC50 = 3.8 X 10(-9) M). In addition, the corresponding P1-P1' Leu psi[CH(OH)CH2]Val and Leu psi[CH2NH]Val derivatives of compound 12 were potent renin inhibitors: Ac-Ftr-Pro-Phe-His-Leu psi[CH(OH)CH2]Val-NH2 (13; IC50 = 3.1 X 10(-10) M) and Ac-Ftr-Pro-Phe-His-Leu psi[CH2NH]Val-NH2 (14; IC50 = 2.1 X 10(-8) M). The structure-conformation-activity properties of the N-terminal Ftr substitution of these human renin inhibitors was examined by (1) comparative analysis of several analogues of 1 and Ac-Ftr-Pro-Phe-His-Sta-Ile-NH2 (17; IC50 = 1.0 X 10(-10) M) having P5 site modifications by Trp, His, D-Ftr, and D-His, (2) deletion of the N-terminal Ftr residue from compounds 12 and 17, to provide Ac-Pro-Phe-His-Sta-Ile-NH2 (16; IC50 = 3.1 X 10(-8) M) and Ac-Pro-Phe-His-Sta-NH2 (15; IC50 = 5.6 X 10(-6) M), and (3) computer modeling and dynamics studies of compounds 1 and 17 bound to CKH-RENIN, a simulated human renin model, which were focused on identifying potential intermolecular interactions of their common P5-P2 sequence, Ac-Ftr-Pro-Phe-His, at the enzyme active site.(ABSTRACT TRUNCATED AT 400 WORDS)

  A structure-activity analysis of peptides containing backbone C alpha-methyl and N alpha-methyl modifications led to the discovery of potent renin inhibitors with high metabolic stability. In vitro, Boc-Pro-Phe-N alpha-MeHis-Leu psi-[CHOHCH2]Val-Ile-Amp (XII) is a potent inhibitor of human plasma renin with IC50 of 0.26 nM. It is a much weaker inhibitor of other aspartic proteases such as porcine pepsin

  A structure-activity analysis of peptides containing backbone C alpha-methyl modification at the P4 site of the angiotensinogen sequence led to the discovery of potent renin inhibitors with apparent in vitro metabolic stability. Boc-alpha-MePro-Phe-His-Leu psi[CHOHCH2]Val-Ile-Amp dicitrate (Va) is a potent inhibitor of human plasma renin with an IC50 value of 1.8 nM. This peptide was shown not to be degraded in vitro by chymotrypsin, elastase, pepsin, and a rat liver homogenate preparation. It is also a potent inhibitor of hog renin with an IC50 value of 1.6 nM and was shown to elicit in vivo activity and cause dose-dependent hypotensive responses when given intravenously to anesthetized ganglion-blocked, hog renin infused rats.
