To examine the roles of aromatic rings, Tyr residues at positions 1 and 5 and Phe residues at positions 16, 17, and 19 of rat neuromedin U-23 (NMU-23) (Tyr-Lys-Val-Asn-Glu-Tyr-Gln-Gly-Pro-Val-Ala-Pro-Ser-Gly-Gly-Phe-Phe-Leu-Phe-Arg-Pro-Arg-Asn-NH2) for reducing food intake activity in male Wistar rats, two NMU-23 analogues, [Phe(4F)16,17,19] NMU-23 and(More)
A selective B-lymphocyte-differentiating tripeptide, bursin, H-Lys-His-Gly-NH2, and its 10 analogs were synthesized by a solid-phase method and were tested for their effect on reduced B lymphocytes of uremic patients. Incubation of peripheral lymphocytes isolated from uremic patients with the synthetic bursin showed an enhancing effect on the reduced B(More)
A thymosin beta 4-like peptide, thymosin beta Met9 isolated from pork spleen, was synthesized using a conventional solution method. The deprotection of the protected thymosin beta Met9 was achieved by treatment with Zn-90% AcOH to remove C-terminal p-nitrobenzyl ester and then with 1 M trifluoromethanesulfonic acid-thioanisole (molar ratio, 1:1) in(More)
