Litorin is a peptide originally isolated from L. aurea that has diverse biological activities.1,2,3,4 It is an agonist of the gastrin-releasing peptide receptor (GRPR) and the neuromedin B (NMB) receptor in BALB/c 3T3 fibroblasts expressing the human receptors (EC50s = 0.44 and 0.03 nM, respectively) and binds to frog bombesin receptor subtype 4 (BB4) in CHO-K1 cells (Ki = 1.2 nM).2,3 Litorin (10-100 ng/kg) induces contractions of isolated guinea pig gallbladder.4 It decreases food intake in rats when administered at doses ranging from 4 to 128 µg/kg.1
