生物活性

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.

IC50 & Target

Ki: 0.17 nM (Human BB1 receptor), 0.66 nM (Rat BB1 receptor), 1 nM (Human BB2 receptor), 16 nM (Rat BB2 receptor)[1]
EC50: 0.31 μM (FPR1), 0.66 μM (FPR2)[2]

體外研究
(In Vitro)

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 inhibits acidification responses to neuromedin-B or neuromedin-C at the human BB1 or BB2 receptors expressed in CHO cells, with the appKBs of 4.0 nM or 13 nM, and blocks bombesin-evoked increases in intracellular calcium levels in CHO cells stably expressing human BB1 or BB2 receptors, with appKBs of 2.3 nM and 36 nM, 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. PD176252 activates Ca2+ mobilization in HL-60 cells transfected with human FPRs (EC50, 0.72 ± 0.21 μM)[2]. PD176252 inhibits little specific 125I-gastrin releasing peptide binding to NCI-H345 cells at 1 nM and suppresses almost all specific bindings at 1000 nM, with an IC50 of 30 nM. PD176252 (10, 30 μM) significantly inhibits the growth of NCI-H345 or H1299 cells, with IC50s of 7 and 5 μM[3].

Cell Assay
[3]

Growth studies in vitro are conducted using the MTT colorimetic assays. NCI-H1299 cells (104/well) are placed in SIT medium and various concentrations of PD176252 or PD168368 added. After 4 days, MTT is added. After 4 h, 150 μL of DMSO is added. After 16 h, the optical density at 570 nm is determined[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3]

Mice[3]
Female athymic Balb/c nude mice, 4-5 weeks old, are housed in a pathogen-free temperature controlled isolation room, with a diet consisting of autoclaved rodent chow and autoclaved water given ad libitum. NCI-H1299 cells (1×107) are injected into the right flank of each mouse by subcutaneous injection. Palpable tumors are observed in approximately 90% of the mice after 1 week. Polyethylene glycol (PEG, 100 μL) or PD176252 (10 or 1 μg in 100 μL of PEG 400) are injected daily by gavage. The tumor volume (height×width×depth) is determined weekly by calipers and recorded[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
