体外研究

FK-506和环孢霉素A阻断细胞质成分的移位，而不影响T淋巴细胞中核亚基的合成。[1] FK-506通过抑制需要白细胞介素-2转录诱导的Ca(2+)-依赖过程，阻止T细胞增殖。[2] FK 506结合于不同的细胞内蛋白质(免疫亲和素)家族，学术上称为亲环素类和FK 506结合蛋白(FKBPs)。FK-506特异性抑制细胞内磷酸酶，在药物浓度下，抑制活化的T细胞中白介素2的产生。[3] FK-506和CsA通过抑制早期钙相关的涉及淋巴因子表达，凋亡，和脱粒作用，在细胞中几乎发挥相同的生物学作用。FK-506与细胞内受体家族结合，学术上称为FK-506结合蛋白(FKBPs)。[4]

PubMed: 23470533     


Effect of FK506 on protein expressions of p-JNK, p-ERK, cytosolic cytochrome c and cleaved caspase-3. Cells were incubated either in the absence of (control) or in the presence of FK506 (12.5, 25 and 50 μM) for 8 h, and protein expressions of p-JNK, p-ERK, cytosolic cytochrome c and cleaved caspase-3 were determined using western blotting.

体内研究 大鼠行为疼痛评估中，FK-506导致痛觉过敏和异常疼痛刺激下爪子和尾巴收缩的阈值增加。在大鼠体内，FK-506也会导致血清硝酸盐和硫代巴比妥酸活性产物(TBARS)水平降低，并伴随组织髓过氧化物酶(MPO)和总钙水平降低，然而，会升高组织中还原型谷胱甘肽的水平。在缺血再灌注损伤(I/R)的大鼠体内，FK-506可以改善加重的神经水肿和轴突变性。[5]

常见问题及建议解决方法

  • 问题 1：

    we would like to inject it subcutaneously into rats, Can we mix the FK506 with 5% dextrose to a concentration of 5mg/ml to prepare the solution?

  • 回答：

    You can dissolve FK506 with DMSO to prepare the stock solution, and then dilute by 5% dextrose. However, we don't have the information about the solubility in this condiation. Or you can use the vehicle we tested: 30% PEG400/0.5% Tween80/5% propylene glycol (Solubility: 30mg/ml).
