ENZYME AND RECEPTOR MODULATION
-
Page/Page column 14; 15, (2010/12/29)
Covalent conjugates of an α,α-disubstituted glycine ester and a modulator of the activity of a target intracellular enzyme or receptor, wherein the ester group of the conjugate is hydrolysable by one or more intracellular carboxylesterase enzymes to the corresponding acid and the α,α-disubstituted glycine ester is conjugated to the modulator at a position remote from the binding interface between the inhibitor and the target enzyme or receptor pass into cells and the active acid hydrolysis product accumulates within the cells.

Synthesis and pharmacological evaluation of glycine-modified analogues of the neuroprotective agent glycyl-L-prolyl-L-glutamic acid (GPE)
Lai, Michelle Y.H.,Brimble, Margaret A.,Callis, David J.,Harris, Paul W.R.,Levi, Mark S.,Sieg, Frank
, p. 533 - 548 (2007/10/03)
The synthesis of 10 G*PE analogues, wherein the glycine residue has been modified, is described by coupling readily accessible dibenzyl-l-prolyl-l- glutamate 2 with various analogues of glycine. Pharmacological evaluation of the novel compounds was undertaken to further understand the role of the glycine residue on the observed neuroprotective properties of the endogenous tripeptide GPE.

Zinc promoted rapid and efficient synthesis of Fmoc- and Z-α,α-dialkylamino acids under neutral conditions

, p. 70 - 74 (2007/10/03)
The introduction of Nα-9-fluorenylmethyloxycarbonyl (Fmoc) and benzyloxycarbonyl (Z) groups into α,α-dialkylamino acids is described at neutral pH using Fmoc-Cl or Z-Cl as an acylating agent respectively in the presence of activated zing powder. The reaction is simple, fast and clean. It also permits the scale up with high yields. It is completely free from protected oligomer formation, which is a known side-reaction when Schotten-Baumann procedure is followed. All the Fmoc- and Z-amino acids prepared have been fully characterized.
Efficient large scale preparation of neutral endopeptidase/ angiotensin-converting enzyme dual inhibitor CGS30440

The development and piloting of a potential manufacturing process for ACE/NEP dual inhibitor CGS30440 is described. The synthesis proceeds sequentially from 1-aminocyclopentanecarboxylic acid via N-protection, peptide coupling with L-tyrosine ethyl ester, O-methylation of N-protected [(1-amino-1-cyclopentyl)carbonyl]-L-tyrosine ethyl ester, N-deprotection, peptide coupling of [(1-amino-1-cyclopentyl)carbonyl]-O-methyl-L-tyrosine ethyl ester with D-2-bromo-3-methylbutyric acid, and final displacement of bromide with thioacetate. This approach is superior to shorter Discovery routes based upon final peptide coupling of L-2-(acetylthio)-3-methylbutanoic acid to [(1-amino-1-cyclopentyl)carbonyl]-O-methyl-L-tyrosine ethyl ester.
