MedKoo CAT#: 571164

CAS#: 119295-94-2

Description: A 65186 is a Type A Cholecystokinin (CCK) receptor antagonist. Cholecystokinin (CCK) is a peptide hormone which is found both in the gastrointestinal tract throughout the human small intestine and in the enteric and central nervous system. It has a potential therapeutic role as an appetite suppressor.
