Amino Acid Sequence

Trp-Met-Asp-Phe-NH2

一般說明

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.

應用

胆囊收缩素片段 30-33 酰胺可用于灭活 CCK8 抗血清。 该产品还可作为抗原,用于检测抗血清的特异性吸收控制。

生化/生理作用

胆囊收缩素片段 30-33 酰胺也称为 CCK-4 或 Trp-Met-Asp-Phe 酰胺是衍生自肽激素胆囊收缩素的肽片段。CCK-4 是引起人惊恐发作的惊恐试剂。该化合物的这一特性可用在科学研究中测试新的抗焦虑药。

Benzodiazepine effects on cholecystokinin tetrapeptide (CCK-4)-induced panic attack (PA) in humans are incompletely characterized, in particular on the neurofunctional level.

Cholecystokinin (CCK) is a neurotransmitter found in high density in the brains of mammals. Microiontophoretic studies showing that benzodiazepines selectively antagonized CCK-induced excitation of rat hippocampal neurons have led to the hypothesis that CCK is an anxiogenic peptide. The hypothesis
