一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

资料参考

Leflunomide(来氟米特)是芳香烃受体(AHR)的激动剂[1]。Leflunomide是可以口服的免疫调节剂。A771726(teriflunomide)是由leflunomide形成的非酶促活性药[2]。

研究表明,Leflunomide可以增加外周血和干细胞亚群的Tregs水平,增加这些细胞向受损的肾的迁移。在缺血再灌注肾中,Leflunomide可以增加细胞IL-10的表达,减少IL-17和IL-23的表达[1]。

在雄性脓毒症Wistar大白鼠中,Leflunomide显著降低脂质过氧化。同时,leflunomide成功地抑制肠中蛋白质羰基和NO的增加[2]。在人MTC-TT细胞中,Leflunomide以剂量和时间依赖的方式减少细胞增殖,抑制肿瘤标志物表达以及下调神经内分泌标记物ASCL1的蛋白表达[3]。

试验操作

Cell experiment:[1]

Cell lines

Human medullary thyroid cancer cell line TT (MTC-TT cells)

Reaction Conditions

75 ~ 150 μmol/L leflunomide for 2, 4, or 6 d incubation

Applications

Leflunomide treatment down-regulated neuroendocrine markers achaete-scute complex-like 1 (ASCL1) and chromogranin A. Moreover, leflunomide significantly inhibited the growth of MTC-TT cells in a dose- and time- dependent manner.

Animal experiment:[2]

Animal models

Male C57BL/6 mice (10 ~ 12 wk of age)

Dosage form

40 mg/kg

Injected intraperitoneally16 h prior to the induction of renal ischemic reperfusion insult

Applications

Leflunomide treatment increased regulatory T cells and IL-10-positive cells but reduced IL-17- and IL-23-expressing cells in both the peripheral blood and kidney cells, indicative of down-regulation of inflammatory responses. Leflunomide treatment also increased mobilization of stems cells subsets in the peripheral blood and promoted their recruitment into the ischemic-reperfused kidney. Eventually, leflunomide treatment was able to preserve mitochondrial membrane potential as well as decrease apoptosis and necrosis of renal cells.
