Even though several of RFamide peptides have been shown to modify memory and learning processes in different species, almost nothing is known regarding cognitive effects of recently discovered neuropeptide QRFP. Considering multiple physiological functions of QRFP, localization of QRFP-synthesizing neurons

The present study was undertaken to investigate the in vitro and in vivo pharmacological profile of the novel, nonpeptide neuropeptide Y (NPY) Y1-selective antagonist, BIBP 3226 [(R)-N2-(diphenylacetyl)-N-[(4-hydroxyphenyl)methyl]-D-arginine-am ide], and a recently described peptidic structure [Ile-Glu-Pro-Orn-Tyr-Arg-Leu-Arg-Tyr-NH2, cyclic (2,4'), (2',4)-diamide].

Neuropeptide Y (NPY) is a peptide widely distributed throughout the body that is involved in various physiological processes, including the regulation of feeding behavior and energy homeostasis. 5-Carbamimidamido-2-(2,2-diphenylacetamido)-N-[(4-hydroxyphenyl)methyl]pentanamide (BIBP 3226) is a selective NPY Y1 receptor antagonist with recognized application

BIBP3226 (N2-(diphenylacetyl)-N-[4-hydroxyphenyl)methyl]-D-arginine amide) has been used to examine the presence of neuropeptide Y Y1 receptors in 3 gastrointestinal epithelial preparations, namely the rat jejunum and descending colon mucosae and a human colonic adenocarcinoma cell line. The selective Y1 receptor antagonist

Neuropeptide Y acts directly on the vasculature as a cotransmitter with norepinephrine for an augmented contraction. Little, however, is known about the effects of neuropeptide Y on the microvasculature of human skeletal muscle. Neuropeptide Y signaling has not been studied
