What is BIM187?

Biological Activity

bombesin has common effects on the gastrointestinal tract and feeding behavior. bombesin acts on two types of receptors including one with high affinity for neuromedin b and another with high affinity for bombesin and gastrin-releasing peptide (grp). bim 187is a new peptide of bombesin while bim 189 is a potent bombesin antagonis.

in vitro

bombesin stimulates mainly the bombesin high-affinity receptor, and bim 187 ([d-phe i ,leu 8'9 ]litorin-nhe), a new bombesin agonist, stimulates the bombesin/grp receptor type. [2].

in vivo

to study the mechanism by which bombesin induces satiety, we studied the effect of bim187 on food intake in rats fed 6 h a day. bim 187 at 4 μg/kg, reduced food intake at 30 min significantly, but did not change the total 6-h food intake. bim 189 (10 mg/kg), had no effect on food intake, even at high doses (20 mg/kg). bim 189 selectively reduced bombesin-induced satiety but had no effect on satiety induced by bim 187 [2].
