产品描述 | PD176252 is a potent BB1 and BB2 antagonist with inhibitory effects on BB1 and BB2 receptors.PD176252 acts as a small molecule GRPR inhibitor and FPR1/FPR2 agonist to inhibit the growth and proliferation of a variety of cancer cells. |
靶点活性 | FPR1:0.31 μM (EC50), BB2 receptor:16 nM (Rat), BB1 receptor:0.66 nM (Ki, Rat), FPR:0.72±0.21 μM (EC50, human), FPR2:0.66 μM (EC50), BB1 receptor:0.17 nM (Ki, Human), BB2 receptor:1 nM (Ki, Human) |
体外活性 | PD176252 is a potent antagonist of neuromedin-B preferring (BB1) and gastrin-releasing peptide-preferring (BB2) receptors with Kis of 0.17 nM and 1 nM for human BB1 and BB2 receptors, and 0.66 nM and 16 nM for Rat BB1 and BB2 receptors, respectively. In CHO cells expressing human BB1 or BB2 receptors, PD176252 inhibits acidification responses to neuromedin-B or neuromedin-C with appKBs of 4.0 nM or 13 nM. It also 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 additionally an agonist of N-Formyl peptide receptor1/2 (FPR1/FPR2), with EC50s of 0.31 and 0.66 μM in HL-60 cells. It activates Ca2+ mobilization in HL-60 cells transfected with human FPRs (EC50, 0.72 ± 0.21 μM)[2]. PD176252 shows little specific 125I-gastrin releasing peptide binding to NCI-H345 cells at 1 nM, suppressing almost all specific bindings at 1000 nM, with an IC50 of 30 nM. Furthermore, PD176252 (10, 30 μM) significantly inhibits the growth of NCI-H345 or H1299 cells, with IC50s of 7 and 5 μM[1]. |
体内活性 | Orally administered PD176252 (1, 10 μg) potently inhibits the growth and proliferation of NCI-H1299 xenografts in nude mice[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
