Synthesis of Levamisole Ferulate and Its Effects on Immune Function of Mice

目的合成左旋咪唑阿魏酸盐(LF),进一步研究左旋咪唑阿魏酸盐对免疫低下小鼠免疫功能的影响,为调节动物免疫状态和改善机体防御能力提供实验依据。方法以盐酸左旋咪唑和阿魏酸钠为原料合成左旋咪唑阿魏酸盐。通过腹腔注射环磷酰胺(CTX)建立小鼠免疫功能低下模型,观察测定左旋咪唑阿魏酸盐对小鼠免疫器官指数和血清免疫球蛋白IgA、IgG、IgM含量等实验指标的影响,验证其免疫增强效果,并进行比较。结果合成得到了目标化合物,产率为80.49%,并通过元素分析、薄层色谱、紫外光谱、红外光谱、质谱等方法对其结构进行了初步验证。左旋咪唑阿魏酸盐能明显促进环磷酰胺诱导的免疫低下小鼠血清IgM和IgG的生成;显著提高胸腺和脾脏指数。结论所设计的合成工艺简单易行,左旋咪唑阿魏酸盐对小鼠的免疫功能具有显著的调节作用。

OBJECTIVE To prepare levamisole ferulate （LF） and investigate its effects on the immune function of mice with low immunity, thus to provide basic evidence for regulation of the immune status of animals and improvement of body＇s defense. METH- ODS LF was synthesized by levamisole hydrochloride and sodium ferulate. The model of immune inhibited mice was estabhshed by intraperitoneal injection with cyclophosphamide （CTX）. In order to verify and compare the effect of immune enhancement, a series of parameters were determined such as the immune organ index, the serum IgA, IgG and IgM in cyclophosphamide-induced-immunosu- pressed mice. RESULTS The product was obtained and its yield was 80. 49%. The identification of the product was done by means of elemental analysis, TLC, UV-Vis, IR and ESI-MS. LF significantly increased the contents of IgM and IgG in cyclophosphamide-in- duced-immunosupressed mice and improved the thymus and spleen indexes. CONCLUSION This synthetic technique is simple and feasible. LF can significantly regulate the immune function in mice.
