  Inhibitors of human renin with C-termini derived from amides and esters of .alpha.-mercaptoalkanoic acids

  摘要：

  New transition-state analogues bearing C-termini derived from alpha-mercaptoalkanoic acids, esters, and amides were prepared and evaluated as inhibitors of human renin. Addition of alpha-mercaptoalkanoate esters to a chiral Boc-amino epoxide intermediate led ultimately to the target [(2R,3S)-3-(BocPheHis-amino)-4-cyclohexyl-2-hydroxy-1-butyl]thio derivatives. The corresponding sulfoxide and sulfone analogues were also investigated. Some of these derivatives, including one with a stable BocPhe replacement, were relatively potent inhibitors of human plasma renin, having IC50 values below 10 nM. When selected compounds were administered intravenously to sodium-deficient rhesus monkeys (Macaca mulatta) at 0.06-1 mg/kg, they reduced plasma renin activity by 87-94%. However, the accompanying drop in blood pressure was of short duration.

  structure-activity relationships (SAR) for a novel dipeptide series inhibitors are reported. These inhibitors retain the Phe8-His9 portion of angiotensinogen and employ a unique Leu10-Val11 replacement [(LVR), ref 2]. SAR at the Leu10 side chain revealed that the LVR derived from cyclohexylalanine provided a nearly 10-fold boost in potency for the final inhibitor. In addition SAR work was carried out to delineate the

  Novel amino acid-derived iodo-N,O-acetonide aminals were developed as chiral, non-epimerizable scaffolds to facilitate complex molecule synthesis. These scaffolds are readily prepared from commercially available amino acid derivatives in ⩽6 steps, contain an orthogonally-protected β-hydroxy amine moiety, and feature a directly reactive alkyl-iodide group for facile substitution chemistry. Further,

  The design and synthesis of hydroxyethylamine isosteres as inhibitors of cathepsin D based on SAR data have been accomplished. A library of 96 of these hydroxyethylamine isosteres are described and many have proven to be very potent inhibitors of human cathepsin D activity as measured using a fluorometric assay technique, via peptide substrate Ac-Glu-Glu(Edans)-Lys-Pro-Ile-Cys-Phe-Phe-Arg-Leu-Gly-Lys(Methyl Red)-Glu-NH2. Compounds showing strongest inhibition of cathepsin D activity were those that contain a hydroxyethyl-N’-2- or N’-(4-chlorophenyl)piperazine moiety (IC50 values range from 0.55 to 8.5 nM), with N’-(2-pyrimidyl)piperizine (IC50 values range from 0.5 to 21.6 nM), with NN’- L-piperazinocolinamide (IC50 values range from 0.001 – 0.25 nM), or N-N’-L-piperazinocolin-N-methylamide (IC50 values range from 0.015 – 7.3 nM) .
