Prolylleucine (((Benzyloxy)carbonyl)-L-prolyl-D-leucine) is a dipeptide containing branched-chain amino acids.

Delta (Phospho) Sleep Inducing Peptide (DSIP-P), a peptide that promotes sustained sleep, induces changes in circadian locomotor activity in rats [1][2][3].

Potent, endogenous neuromedin U receptor agonist (EC50 values are 65 and 91 pM at NMU1 and NMU2 respectively). Induces phase shifts in the circadian rhythm of locomotor activity following i.c.v. administration. Potent endogenous anorexigenic peptide.

Neuropeptide Y (NPY) is a 36-amino acid neuropeptide that exerts its activity via G-protein-coupled receptors. NPY is widely distributed in the peripheral and central nervous systems. It modulates a variety of physiological processes, e.g. the central reg
