Potent and selective peptide orexin OX1 receptor agonist (EC50 values are 8.29 and 187 nM for OX1 and OX2 receptors respectively). Truncated form of orexin A.
GP(33-41), a 9-aa-long peptide, is the optimal sequence of the GP1 epitope of lymphocytic choriomeningitis virus and can upregulate H-2Db molecules at the RMA-S (Db Kb) cell surface with an SC50 of 344 nM. GP33-41 Epitope is a strong agonist of CD8 T cells.
Antibacterial Agent 33, a potent antibacterial compound, effectively decreases the minimum inhibitory concentration (MIC) of Ceftazidime, another antibacterial agent.
CCK (27-33) is a C-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. Non-sulfated CCK (27-33) inhibits binding of [3H]naloxone in rat cerebellum membranes (IC50 = 4 uM) and inhibits electrically-stimulated contraction of isolated guinea pig ileum (IC50 = 17 uM), an effect that can be reversed by naloxone. Unlike sulfated CCK (27-33), the non-sulfated form does not reduce exploratory behavior in mice when administered at doses up to 1 uMol/kg.
