Cyclic cholecystokinin analogues that are highly selective for rat and guinea pig central cholecystokinin receptors.

Abstract

Cholecystokinin (CCK) analogues (JMV310, JMV320, JMV328, and JMV332), obtained by side chain to side chain cyclization of a lysine residue in position 28 with a lysine residue in position 31, were found to be highly selective for the brain CCK receptor (CCK-B receptor), both in guinea pig and rat. In these analogues, the C-terminal tetrapeptide region of… (More)
