Potent bombesin receptor agonist (IC50 values are 0.26, 1.55 and 2.52 nM for BB1, BB2 and BB3 respectively). Enhances glucose transport in obese and diabetic primary myocytes. Also stimulates NCI-H1299 lung cancer cell proliferation in vitro.
ICI 216140 is a GRP/bombesin receptor 2 antagonist (IC50: 2 nM in vitro). At 2 mg/kg, it can decrease bombesin-stimulated pancreatic amylase secretion in rats. At 1 mM, it has been proved to attenuate bombesin-stimulated increases in blood pressure in rat
[D-Cys6,Asn7,D-Ala11,Cys14]-Bombesin (6-14),该合成肽是一种非选择性激动剂,作用于蛙皮素受体。它对三种蛙皮素受体的pEC50分别为:神经介素 B 偏好的BB1为8.06、胃泌素释放肽偏好的BB2为8.69、以及孤儿受体BB3为6.71。此化合物被用于涉及蛙皮素受体的疾病研究,包括癌症和神经系统疾病等。
