Gastrin-releasing peptide is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

TAT-amide is a cell penetrating peptide. Cell-penetrating peptides (CPPs) are short amino acid sequences able to enter different cells.

Isopulegol presents depressant- and anxiolytic-like effects, it also has anticonvulsant and bioprotective effects against PTZ-induced convulsions are possibly related to positive modulation of benzodiazepine-sensitive GABAA receptors and to antioxidant properties.
