α-Methyl tryptophanylphenylalanines and their arylethylamine 'dipeptoid' analogues of the tetrapeptide cholecystokinin (30-33)
A series of N-alkyl carbamate blocked α-Me-Trp-Phe and α-Me-Trp-phenethylamides has been identified as 'dipeptoid' analogues of CCK-4 (CCK 30-33). These compounds have micromolar affinity for the type-B central CCK receptor, some of which increase the fir
