CCK-4 (holecistokininski tetrapeptid, Trp-Met-Asp-Phe-NH2; ili PTK7) je peptidni fragment izveden iz većeg peptidnog hormona holecistokinina. Za razliku od holecistokina koji ima niz uloga u gastrointestinalnom sistemu kao i u centralnom nervnom sistemu, CCK-4 deluje prvenstveno u mozgu kao stimulator anksioznosti. On pokazuje slabe GI efekte, za razliku od CCK-8 ili polipeptida pune dužine, CCK-58.

CCK-4 proizvodi jake simptome anksioznosti u malim dozama, kao što je 50 μg,[1] i često se koristi u naučnim istraživanjima za indukovanje paničnih napada s ciljem testiranja novih anksiolitika.[2][3][4][5] Pošto je on peptid, CCK-4 mora biti administriran putem injekcije. U telu se brzo razlaže, tako da ima kratkotrajno dejstvo.[6] Brojni sintetički analozi sa modifikovanim osobinama su poznati.[7][8][9][10][11][12][13][14][15][16][17]
