Boc-CCK-4 derivatives containing side-chain ureas as potent and selective CCK-A receptor agonists

Article abstract of DOI:10.1021/jm00113a023

Novel Boc-CCK-4 derivatives were communicated recently as having high potency and selectivity for the CCK-A receptor (Shiosaki et al. J. Med. Chem. 1990, 33, 2950-2952). While Boc-CCK-4 binds selectively to the CCK-B receptor, replacement of the methionin
