Description

Amino Acid Sequence

cyclo-Phe-Trp-Lys-Thr-Bzl

Application

Cyclo(7-aminoheptanoyl-Phe-D-Trp-Lys-Thr[Bzl]) has been used as a somatostatin antagonist to study its effects on sleep in rats to infer the role of endogenous somatostatin in the physiologic modulation of REM sleep (REMS) , as an somatostatin (SST) antagonist to study its effects on elemental-induced intestinal atrophy in rats , as an SST receptor antagonist to eliminate the effect of somatostatin on catecholamine .

Biochem/physiol Actions

Cyclo(7-aminoheptanoyl-Phe-D-Trp-Lys-Thr[Bzl]) (cSSTA) is a cyclic somatostatin (SST) analog and is a somatostatin receptor antagonist. It is involved in blocking the effect of somatostatin, such as airway β-adrenergic function and regulation of acetylcholine release. cSSTA is also involved in blocking the effect of somatostatin of hormone release and corticotropin-releasing factor-induced suppression of gastric emptying.

Cyclo(7-aminoheptanoyl-Phe-D-Trp-Lys-Thr[Bzl]), also known as cyclosomatostatin. Inhibition of somatostatin receptors by cyclosomatostatin induces catalepsy in rats.
