BIM-26226
Based on 1 Customer Validation
BIM-26226 is a selective gastrin-releasing peptide receptor (GRPR) (IC50 = 6 nM) and bombesin receptor (BN receptor) antagonist. BIM-26226 antagonizes BN- or GRP-stimulated amylase release with IC50 values of 0.3 nM and 0.2 nM, respectively. BIM-26226 is specific for the GRP-preferring BN receptor subtype with no interference with GRP receptor system. BIM-26226 can induce the synthesis of somatostatin receptor but has no significant effect on tumor growth.

Biological Activity
bombesin receptor[1]
BIM-26226 (0.1 nM-1 μM, 24 h) significantly decreased [3H]thymidine incorporation in primary cultured pancreatic tumour cells[1].
BIM-26226 is specific for the GRP-preferring BN receptor subtype and is not able to inhibit binding of radio-labeled CCK-33, gastrin-17 or VIP in AR4-2J cells[2].
BIM-26226 (0.1 μM) is able to block the bombesin-induced increase of Ca2+ but fails to block the growth-stimulatory effect of bombesin[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
BIM-26226 (100 μg/kg, s.c., once daily for 6 weeks) induces the synthesis of somatostatin receptor but has no effect on tumor growth in colon cancer rat model[3].
