- Mercaptoacyl amino acid inhibitors of atriopeptidase. 1. Structure- activity relationship studies of methionine and S-alkylcysteine derivatives
-
A broad series of N-(3-mercaptoacyl) amino acid derivatives was evaluated for their ability to inhibit atriopeptidase (neutral endopeptidase, EC 3.4.24.11) in vitro and in vivo. Structural parameters studied were (i) the substituent on the 2-position of the 3-mercaptopropionyl moiety, (ii) the amino acid component, (iii) the S-terminal derivative, and (iv) the C- terminal derivative. Optimum activity was observed for derivatives of methionine and S-alkylcysteines. N-[3-Mercapto-2(S)-[(2- methylphenyl)methyl]-1-oxopropyl]-L-methionine was identified as a highly effective inhibitor of atriopeptidase meriting evaluation as a potential cardiovascular therapeutic agent.

- Oxidative Deblocking of the 4-Methoxybenzyl Thioether Protecting Group: Application to the Directed Synthesis of Poly-cystinyl Peptides
-
The 4-methoxybenzyl thioether protecting group is deblocked efficiently by oxidation with the homogeneous electron transfer agent tris(4-bromophenyl)ammoniumyl (2.+) leading to the disulfide in high yields.S-(4-methoxybenzyl)cysteine derivatives like 9 in this way can be transformed into the corresponding cystine derivatives like 10 in 90percent yield.Many N and carboxy protecting groups like the Boc and Z group and tert-butyl or benzyl ester functions are stable under the cleavage conditions.On the other hand the 4-methoxybenzyl thioether protecting group is totally unaffected by the conditions for oxidative deblocking of the S-trityl functions by either iodine or rhodanolysis.This opens up new opportunities for the directed synthesis of cystinyl peptides with more than one intra- or interchain disulfide bridge.Application of the new method to the synthesis of a cystine peptide with one intrachain S-S-bridge and a double-chain biscystinyl peptide is reported.
