Neuropeptide S (human)

Neuropeptide S human, a neuropeptide, is a potent cognate neuropeptide S receptor (NPSR) agonist. Neuropeptide S human can be used for Alzheimer's disease (AD) research^[1]. IC50 & Target:EC50: 9.4 nM (neuropeptide S receptor)^[1] In Vitro: Half-maximal effective concentrations (EC₅₀) for mobilization of [Ca²⁺]_i are 9.4 nM, 3.2 nM, and 3.0 nM for human, rat, and mouse Neuropeptide S (NPS), respectively^[1].
Neuropeptide S human (4 pM to 1.7 nM; 48 hours) retains full agonist activity with an EC₅₀ of 6.7 nM, the binding of [^125I] Y10-hNPS to CHO cells stably expressing hNPSR is saturable with high affinity (K_d = 0.33 nM)^[1].
Neuropeptide S human (1 pM-3 μM; 48 hours) are used to compete with 0.15 nM [^125II] Y10-NPS, [^125II] Y10-NPS is displaceable by increasing concentrations of human NPS (IC₅₀ = 0.42 nM)^[1].
In Vivo: Neuropeptide S human (0.1 nM-1 nM; i.c.v.) causes a significant increase in locomotor activity, the total distance traveled, percentage of time moving, number of rearing events, and center entries are also significantly increased in mice^[1].
