Synthesis and biological properties of antiparallel and parallel dimers of alpha-human atrial natriuretic peptide.

To obtain antiparallel and parallel dimers of alpha-human atrial natriuretic peptide (alpha-hANP), two fully protected peptides I and II having the same amino acid sequence as alpha-hANP with different protective groups at the cysteinyl residues were synthesized, the former having Acm and Npys and the latter MeBzl and Acm. Equivalent amounts of peptides I… (More)
