    Product Description

    PD 176252 is a nonpeptide antagonist of bombesin receptor subtype 1 (BB1) and BB2 (Kis = 0.17 and 1 nM, respectively).1 It also induces calcium mobilization in HL-60 cells expressing formyl peptide receptor 1 (FPR1) or FPR2/ALX (EC50s = 0.31 and 0.66 µM, respectively).2 PD 176252 inhibits the proliferation of C6 rat glioma cells (IC50 = 2 µM).3 Intracerebroventricular administration of PD 176252 (100 ng/animal) increases social interaction in the social interaction test in rats.4 It decreases the latency to feed in the novelty-suppressed feeding test when administered at a dose of 10 mg/kg.

    WARNING This product is not for human or veterinary use.
