PD176252 is a potent antagonist of neuromedin-B preferring (BB 1 ) and gastrin-releasing peptide-preferring (BB 2 ) receptor with K i s of 0.17 nM and 1 nM for human BB 1 and BB 2 receptors, and 0.66 nM, 16 nM for Rat BB 1 and BB 2 receptors, respectively. PD176252 inhibits acidification responses to neuromedin-B or neuromedin-C at the human BB 1 or BB 2 receptors expressed in CHO cells, with the appK B s of 4.0 nM or 13 nM, and blocks bombesin-evoked increases in intracellular calcium levels in CHO cells stably expressing human BB 1 or BB 2 receptors, with appK B s of 2.3 nM and 36 nM, respectively. PD176252 is also an agonist of N-Formyl peptide receptor1/2 (FPR1/FPR2), with EC 50 s of 0.31 and 0.66 μM in HL-60 cells. PD176252 activates Ca 2+ mobilization in HL-60 cells transfected with human FPRs (EC 50 , 0.72 ± 0.21 μM). PD176252 inhibits little specific 125 I-gastrin releasing peptide binding to NCI-H345 cells at 1 nM and suppresses almost all specific bindings at 1000 nM, with an IC 50 of 30 nM. PD176252 (10, 30 μM) significantly inhibits the growth of NCI-H345 or H1299 cells, with IC 50 s of 7 and 5 μM.
PD176252 (1, 10 μg, p.o.) potently inhibits the growth of the proliferation of NCI-H1299 xenografts in nude mice.
