Chemical structure of Pacap38

GA23341

Pacap38

Also listed as PACAP-38 (human, mouse, ovine, porcine, rat)

Kojro et al· observed that the PAC1 agonists PACAP-27 (H-1172) and PACAP-38 strongly increased the activity of α-secretase· Upregulation of this APP-degrading enzyme promotes the non-amyloidogenic processing of APP, i·e· reduces the production of Aβ40/42, and thus may help to prevent Alzheimer's disease· Nasally applied PACAP-38 in APP[V717I]-transgenic mice additionally enhanced the production of the Aβ-degrading enzyme neprilysin via induction of somatostatin
