PACAP (1-27) (human, mouse, ovine, porcine, rat) (trifluoroacetate salt)

Pituitary adenylate cyclase-activating peptide (PACAP) (1-27) is a PACAP receptor agonist with IC50 values of 3, 2, and 5 nM, respectively, for rat PAC1, rat VPAC1, and human VPAC2 recombinant receptors expressed in CHO cells. It binds to PACAP receptors in rat brain membrane (IC50 = 9.55 nM) and to SH-SY5Y and SK-N-MC human neuroblastoma and T47D human breast cancer cells (IC50s = 1.1, 1.9, and 0.9 nM, respectively). PACAP (1-27) stimulates cAMP accumulation in H-SY5Y, SK-N-MC, and T47D cells (EC50s = 0.19, 0.22, and 0.17 nM, respectively). In vivo, in newborn pigs, PACAP (1-27) (1 µM) induces vasodilation of pial arterioles by 36%.Formal Name: L-histidyl-L-seryl-L-alpha-aspartylglycyl-L-isoleucyl-L-phenylalanyl-L-threonyl-L-alpha-aspartyl-L-seryl-L-tyrosyl-L-seryl-L-arginyl-L-tyrosyl-L-arginyl-L-lysyl-L-glutaminyl-L-methionyl-L-alanyl-L-valyl-L-lysyl-L-lysyl-L-tyrosyl-L-leucyl-L-alanyl-L-alanyl-L-valyl-L-leucinamide, trifluoroacetate salt.
