BIM187 Usage And Synthesis

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].
