产品描述 | Rolipram (SB 95952) is a phosphodiesterase 4 inhibitor with antidepressant properties. |
靶点活性 | PDE4B:130 nM, PDE4D:240 nM |
体外活性 | The PDE4 selective inhibitor, Rolipram, inhibits immunopurified PDE4B and PDE4D activities similarly, with IC50s of approx. 130 nM and 240 nM respectively. In contrast, Rolipram inhibits immunopurified PDE4A activity with a dramatically lower IC50 of around 3 nM. Rolipram increases phosphorylation of cAMP-response-element-binding protein (CREB) in U937 cells in a dose-dependent fashion, which means that both high affinity (IC50 approx. 1 nM) and low affinity (IC50 approx. 120 nM) components are presented. Rolipram dose-dependently inhibits the IFN-gamma-stimulated phosphorylation of p38 MAPK in a simple monotonic fashion with an IC50 of approx. 290 nM[1]. Rolipram is a selective PDE4 inhibitor that inhibits all PDE4 isoforms A, B, C and D. Rolipram inhibits LPS-induced TNF production in a dose-dependent manner (IC50 25.9 nM), and maximal/submaximal inhibition is observed with 2 μM drug concentration in J774 cells[2]. |
体内活性 | TNF mRNA and protein expression is induced by LPS in peritoneal macrophages (PM) from WT mice, and that is clearly (by 74 and 63% for TNF mRNA and TNF protein, respectively) inhibited by Rolipram. LPS-induced TNF production is enhanced in PM from MKP-1(-/-) mice as compared to that in PM from WT mice, which is consistent with the published results. Interestingly, the inhibition of TNF mRNA and protein expression by Rolipram is markedly attenuated in PM from MKP-1(-/-) mice and does not reach statistical significance[2]. Repeated administration of Rolipram (1.25 mg/kg, i.p.) reduces the number of escape failures in learned helplessness rats[3]. |
细胞实验 | Rolipram is dissolved in DMSO and stored, and then diluted with appropriate medium before use[2]. J774 murine macrophages (ATCC) are cultured at 37°C in 5% CO2 atmosphere in DMEM supplemented with glutamax-1 containing 10% heat-inactivated FBS, 100 U/mL penicillin, 100 μg/mL streptomycin and 250 ng/mL amphotericin B. For experiments, cells are seeded on 24-well plates at a density of 2×105 cells per well. Cell monolayers are grown for 72 h before the experiments are started. Rolipram, IBMX and BIRB 796 are dissolved in DMSO, and 8-Br-cAMP in HBSS. LPS (10 ng/mL) or the compounds of interest at concentrations indicated or the solvent (DMSO, 0.1% v/v) are added to the cells in fresh culture medium containing 10% FBS and the supplements. Cells are further incubated for the time indicated. The effect of LPS and the tested chemicals on cell viability is evaluated by Cell Proliferation Kit II (XTT)[2]. |

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。
