(D-Arg1,D-Pro2,D-Trp7,9,L-Leu11)-Substance P (acetate), an antagonist of Substance P and Bombesin, modulates ocular inflammatory responses triggered by antidromic trigeminal nerve stimulation [1].

PGlu-3-methyl-His-Pro-NH2 TFA enhances binding to pituitary TRH receptors, thereby increasing the stimulation of thyroid-stimulating hormone (TSH) release from the pituitary.

Mca-Pro-Leu-NH2 is a peptide compound and a substrate for matrix protease assays.

Ac-Ser-Gln-Asn-Tyr-Pro-Val-Val-NH2 is a peptide substrate specific to HIV-1 protease, used as the variable component in peptidolytic assays designed to measure the enzyme's inhibition [1][2].

H-Gly-Pro-Gly-NH2, a tripeptide, effectively inhibits HIV-1 replication by interfering with capsid formation, demonstrating antiviral activity particularly against HIV-1 III B and HIV-2 ROD with EC 50 values of 35 µM and 30 µM, respectively. This compound's ability to disrupt the viral replication process positions it as a valuable asset for virus research [1] [2] [3].

Ser-parafluoroPhe-Aad-Leu-Arg-Asn-Pro-NH2 is a biologically active peptide. Structure-activity studies of the thrombin receptor-tethered ligand SFLLRNP highlighted the pivotal role of the Phe-2-phenyl group in receptor recognition, while substitution with para-fluorophenylalanine [(p-F)Phe] increased its activity.

pGlu-His-Pro-Gly-NH2, also known as Glp-His-Pro-Gly-NH2, is a tetrapeptide that promotes the release of gonadotropin, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) [1] [2].
