Amino Acid Sequence

Trp-Met-Asp-Phe-NH2

Description générale

Research area: Neuroscience

Several biologically active fragments of the neuropeptide cholecystokinin (CCK) are present in the brain, where they interact with CCK-A and CCK-B receptors. Among these fragments, CCK-4 is notably abundant in the cortical and limbic brain structures. CCK-4, a bioactive form of cholecystokinin, is a peptide hormone that regulates food intake by binding to CCK receptors in the gut and brain.

Application

Cholecystokinin Fragment 30-33 Amide can be used for inactivating the CCK8 antiserum. The product can also be used as an antigen utilized in absorption control for testing the specificity of antisera.Cholecystokinin Fragment 30-33 Amide has been used to induce anxiolytic- and antidepressant-like effects and study the role of neuropeptide Y, in mice.

Actions biochimiques/physiologiques

Cholecystokinin Fragment 30-33 Amide also referred to as CCK-4 or Trp-Met-Asp-Phe amide is a peptide fragment derived from peptide hormone cholecystokinin. CCK-4 is a panicogenic agent that induces panic attacks in humans. This property of the compound can be used in scientific research for testing new anxiolytic drugs.CCK-4 acts selectively through CCK-B receptors and is recognized for its role in regulating emotional behaviors. Studies on CCK knock-down mice have indicated anxiolytic- and antidepressant-like effects.

Conditionnement

Bottomless glass bottle. Contents are inside inserted fused cone.

Notes préparatoires

Cholecystokinin Fragment 30-33 Amide dissolves in Dimethylformamide at 20 mg/ml to yield a clear, colorless to yellow solution.

In this study we examined how personality disposition may affect the response to cholecystokinin tetrapeptide (CCK-4; 50 microg) challenge in healthy volunteers (n=105). Personality traits were assessed with the Swedish universities Scales of Personality (SSP). Statistical methods employed were correlation

Most antianxiety drugs (anxiolytics) work by modulating neurotransmitters in the brain. Benzodiazepines are fast and effective anxiolytic drugs; however, their long-term use is limited by the development of tolerance and withdrawal symptoms. Ligands of the translocator protein [18 kilodaltons (kD)]

Recent efforts have focused on identifying small nonpeptide molecules that can mimic the activity of endogenous peptide hormones. Understanding the molecular basis of ligand-induced receptor activation by these divergent classes of ligands should expedite the process of drug development. Using
