Leflunomide
Leflunomide is an agonist of aryl hydrocarbon receptor (AHR) [1].?As an immunoregulatory agent, Leflunomide can be administrated orally. A771726 (teriflunomide) is an active drug formed non-enzymatically from leflunomide [2].
Leflunomide has been demonstrated to expand Tregs levels in peripheral blood?and stem cells subsets as well as to increase the migration of these cells?into the injured kidney. ?Leflunomide has been displayed to increase cells expressed IL-10 and reduce cells expressed IL-17- and IL-23 in ischemic-reperfused kidney [1].
Leflunomide has shown to significantly lower the lipid peroxidation in male Wistar albino rats of sepsis. Meanwhile, leflunomide successfully inhibited the protein carbonyl rise and NO rise?in bowel [2]. Leflunomide has shown to reduce cell proliferation, inhibit?tumor marker expression, as well as down-regulate neuroendocrine marker ASCL1 protein expression in a dose- and time-dependent manner in human MTC-TT cells [3].

| General tips | We do not recommend long-term storage for the solution, please use it up soon. |
| 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. |
