Lintitript (SR 27897) is a selective cholecystokinin type A (CCK-A) receptor antagonist, which was initially developed by Sanofi for appetite disorders. It is known, that CCK modulates feeding and dopamine-induced behavior in the central and peripheral nervous system. Lintitript presumably alters feeding habits, however, the exact mechanism of action is not known. Lintitript was investigated in animals with anorexia nervosa, in addition, drug was in clinical trial for the patients with advanced pancreatic cancer, but these studies were discontinued.

Sample Use Guides

pancreatic cancer: nineteen patients were enrolled on a 28-day course of SR 27897B (lintitript). Initially, 4 patients received 20 mg of SR 27897B; 9 patients received 40 mg; and 6 patients 80 mg. Imaging studies, including FDG-PET and MRI, were performed at baseline and on days 14 and 28.
Route of Administration: Oral
In Vitro Use Guide
SR 27897 (lintitript) is a potent ligand for CCKA binding sites (rat pancreatic membranes, Ki = 0.2 nM) and is highly selective (CCKB and gastrin/CCKA IC50 ratios of 800 and 5000 respectively). In vitro, it is a competitive antagonist of cholecystokinin (CCK)-stimulated amylase release in isolated rat pancreatic acini (pA2 = 7.50) and of CCK-induced guinea pig gall bladder contractions (pA2 = 9.57).
