title: Pentagastrin analogs containing alpha-aminooxy acids, II. Simultaneous substitutions at the N- and C-terminus.
abstract: Twenty-seven new pentagastrin analogs containing free or protected aminooxy acids at the N-terminus and D-2-aminooxy-3-phenyl-propionic acid, L-(4-chlorophenyl)glycine, L- and D-phenylglycine, or L- or D-cyclohexyglycine instead of the C-terminal L-phenylalanine and analogs extended by aminooxyacetic acid at the C-terminus, were synthesized stepwise. The end products were purified by chromatography on DEAE-cellulose or silica gel.
