Uses

PD176252 is a potent antagonist of neuromedin-B preferring (BB1) and gastrin-releasing peptide-preferring (BB2) receptor with Kis of 0.17 nM and 1 nM for human BB1 and BB2 receptors, and 0.66 nM, 16 nM for Rat BB1 and BB2 receptors, respectively; PD176252 is also an agonist of N-Formyl peptide receptor1/2 (FPR1/FPR2), with EC50s of 0.31 and 0.66 μM in HL-60 cells.

Biological Activity

Non-peptide gastrin-releasing peptide receptor (GRP-R, BB 2 ) and neuromedin B receptor (NMB-R, BB 1 ) antagonist (K i values are 0.17 and 1.0 nM for BB 1 and BB 2 respectively). Inhibits proliferation of rat C6 glioma cells (IC 50 = 2 μ M) and inhibits NCI-H1299 xenograft proliferation in nude mice (IC 50 = 5 μ M).
