[ 靶点 ]

IC50: 7 nM (calcineurin)


[体外研究]

环孢菌素A能够与T细胞中的亲环蛋白结合[1]。环孢菌素A通过形成亲环蛋白-环孢菌素A复合物来抑制神经钙蛋白[2]。环孢菌素A对钙调神经磷酸酶具有抑制作用,IC50为7 nM [3]。环孢菌素A抑制NF-AT的核转位[4]。环孢菌素A通过阻止MTP打开显示对线粒体的影响,IC50为39 nM [5]。

[体内研究]

环孢菌素A具有免疫抑制活性,并且在小鼠,大鼠和豚鼠中通过肠胃外和口服给药具有活性[6]。环孢菌素A可用于器官移植以防止排斥反应[7]。

[激酶实验]

与纯化酶的反应混合物含有100 nM钙调神经磷酸酶,100 nM钙调蛋白和5μM32P标记的磷酸肽,在60μL(总体积)的含有20 mM Tris(pH 8),100 mM NaCl,6 mM MgCl 2,0.5的分析缓冲液中mM二硫苏糖醇,每毫升0.1mg牛血清白蛋白,和0.1mM CaCl 2或5mM EGTA。与细胞裂解物的反应混合物含有20μL未稀释的裂解物,5μM32P标记的磷酸肽和40μL测定缓冲液。反应混合物含有50μM肽412或413和/或500nM冈田酸,磷酸酶1和2A的特异性抑制剂; 500nM冈田酸足以抑制Ca2 +非依赖性磷酸酶,而较高浓度也部分抑制Ca2 +依赖性磷酸酶活性。在30℃下15分钟后,通过加入0.5mL含有5%三氯乙酸的100mM磷酸钾缓冲液(pH7.0)终止反应。通过Dowex阳离子交换色谱法分离游离无机磷酸盐,并如所述通过闪烁计数进行定量。

[细胞实验]

免疫抑制剂以比细胞处理所需浓度高1000倍的浓度溶解在乙醇中。将细胞(106)悬浮于微量离心管中的1mL完全培养基中;加入1μL乙醇或环孢菌素A的乙醇溶液,并将细胞在37℃下孵育1小时。将细胞在冰上用1mL PBS洗涤两次,并在含有50mM Tris(pH 7.5)的50μL低渗缓冲液中裂解; 0.1mM EGTA; 1 mM EDTA; 0.5mM二硫苏糖醇;每毫升50μg苯甲基磺酰氟,50μg大豆胰蛋白酶抑制剂,5μg亮肽素和5μg抑肽酶。将裂解物在液氮中进行三个循环的冷冻,然后在30℃下解冻,然后在4℃下以12,000×g离心10分钟。

[动物实验]

在第0天腹膜内用0 5mL免疫大鼠,小鼠静脉内用0 2mL 10%洗过的绵羊红细胞(SE)悬浮液免疫。为了引起二次反应,在初次免疫后8-11周,用静脉内注射0-2mL的25%洗涤的SE(107个细胞)对小鼠进行加强免疫。对于长期治疗,动物在13周内每天在食物中平均接受45mg / kg环孢菌素A.在杀死前5天对这些大鼠进行免疫。
