substance p (1 9)

Substance P (1-9) is a nonapeptide that reduces the inactivation of substance P in the guinea-pig ileum and urinary bladder, and is responsible for various excitatory effects on central and peripheral neurons.

Substance P 1-9 aceate is nonapeptide, which decreases the inactivation of substance P by the guinea-pig ileum and urinary bladder.

[D-Trp2,7,9] Substance P is a tachykinin (Neurokinin Receptor) antagonist with inhibitory affinities (K_i values) of 1 μM for NK-1, 1.3 μM for NK-2, and approximately 9 μM for NK-3 receptors [1].

PACAP (1-38), a novel neuropeptide isolated from the bovine hypothalamus is more active than vasoactive intestinal peptide (VIP) in stimulating adenylate cyclase (EC50=7 nM). PACAP 1-38 (10-9 M) increased substance P (SP), gastrin releasing peptide (GRP),

[Sar9]-Substance P is one of NK-1 receptor agonist. The action of SP on progesterone metabolism was mimicked by the rNK1-specific agonist [Sar-9,Met(O2)11]-SP.
