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]

体外研究
(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].

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 5.75 mg/mL (9.83 mM); 悬浊液; 超声助溶

    此方案可获得 5.75 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 57.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 5.75 mg/mL (9.83 mM); 澄清溶液

    此方案可获得 ≥ 5.75 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 57.5 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

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.
