| 包装规格: | 25mg 50mg 100mg in glass bottle |
| 产品简介: | 一种免疫亲和素(immunophilin)配体,能特异地与胞质受体(immunophilin macrophilin-12)相结合。 Pimecrolimus is an immunomodulating agent used in the treatment of atopic dermatitis (eczema). It is currently available as a topical cream, once marketed by Novartis (however Galderma is promoting the compound in Canada since early 2007) under the trade name Elidel. Pimecrolimus is an ascomycin macrolactam derivative. It has been shown in vitro that pimecrolimus binds to macrophilin-12(also referred to as FKBP-12) and inhibits calcineurin. Thus pimecrolimus inhibits T-cell activation by inhibiting the synthesis and release of cytokines from T-cells. Pimecrolimus also prevents the release of inflammatory cytokines and mediators from mast cells. |
| 溶解性: | 溶于DMSO(≥30mg/mL) |
| 储备液保存: | -80°C, 2 years; -20°C, 1 year。 |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.5 mg/mL (3.08 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 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。 2、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (3.08 mM); 澄清溶液 此方案可获得 ≥ 2.5 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。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 玉米油中,混合均匀。 注:工作液建议您现用现配,当天使用。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |
| 靶点: | Calcineurin |
| 体外研究: | Pimecrolimus (SDZ-ASM 981)(100 nM) targets T-cells and mast cells and inhibits the production and release of cytokines and other inflammatory mediators, as well as the expression of signals essential for the activation of inflammatory T-lymphocytes. Pimecrolimus acts specifically on cells that are crucial for the effector phase of an inflammatory reaction. Pimecrolimus (10 nM; 3 days) inhibits the polyclonal growth of peripheral blood T cells in murine and human mixed lymphocyte reactions. Pimecrolimus inhibits cytokine IL-2, IL-4, IL-10 and interferon-γ release from T-cell clone CFTS4:3.1 with IC50s of 0.28, 0.3, 0.2 and 0.42 nM, respectively after antigen-specific stimulation. |
| 体内研究: | Pimecrolimus (SDZ-ASM 981) (0-0.4%; topical; 10 μ L once) inhibits allergic contact dermatitis in mice and pigs. Pimecrolimus (0-90 mg/kg; p.o. or s.c.; twice or once) potently inhibits allergic contact dermatitis in mice and rats. |
| 保存条件: | 2-8℃ |
| 注意事项: | 1、为了您的安全和健康,请穿实验服并戴一次性手套操作。 2、以上信息仅做参考交流之用。 |
