β-Casomorphin Fragment 1-5 (BCM5), an opioid receptor agonist, is a member of the β-casomorphin peptide family derived from β-casein. β-casomorphins are used to study their differential effects on processes such as hyperglycemia, oxidative stress, opioid signalling and immunosuppression.
Beta-casomorphins, opioid peptides present in mother's milk, are a good substrate for DPPIV (EC 3.4.14.5) which is a major factor limiting the half-life of biologically active peptides. Serum DPPIV activity of two groups of infants (healthy and atopic dermatitis) and
Healthy young volunteers ingested one liter of cows' milk; then the contents of the small intestine were aspirated through an intestinal tube at various times and assayed for the presence of bovine beta-casomorphin immunoreactive materials. Considerable amounts of beta-casomorphin-7, but
We report the complete assignment of the 1H-nmr spectrum of beta-casomorphin-5 in DMSO-d6 solution. With a combination of one-dimensional, double quantum filtered correlated spectroscopy, homonuclear Hartmann-Hahn, and rotating frame nuclear Overhauser enhancement spectroscopy (ROESY) spectra, we were able to differentiate
We studied the effect of beta-casomorphin-5 (mu-acting opioid peptides derived from milk protein beta-casein) on neurite outgrowth of mouse neuroblastoma cell line, Neuro-2a. Beta-casomorphin-5 stimulated neurite outgrowth of Neuro-2a cells in a naloxone-reversible manner. The stimulating effect of beta-casomorphin-5 was
Cyclic analogues of the beta-casein-derived opioid peptide beta-casomorphin-5 (H-Tyr-Pro-Phe-Pro-Gly-OH) were prepared through substitution of the Pro2 residue with various alpha,omega-diamino acid residues (lysine, ornithine, 2,4-diaminobutyric acid) and cyclization of the omega-amino group to the C-terminal carboxyl function. Compounds of this
