Four kinds of organic acid salts of levamisole were prepared from levamisole hydrochloride and organic acids (L-ascorbic acid, tartaric acid, citric acid and ferulic acid) by solvent crystallization method, respectively. The salts were characterized by elemental analysis, UV-VIS, FTIR, ESI-MS, DSC-TGA, solubility in water, melting point, optical rotation and pH in water. The immunosuppressed mice models were established by intraperitoneal injection of cyclophosphamide to verify and compare the effects of levamisole hydrochloride and organic acid salts of levamisole on immune functions of immunosuppressed mice. The results showed while significantly increasing the contents of serum IgM and IgG and the immune organ indexes in cyclophosphamide-induced immunosuppressed mice, levamisole ferulate and levamisole tartrate presented higher increases in IgG contents and immune organ indexes than other salts did. Thus, it could be concluded that levamisole ferulate and levamisole tartrate were more effective on immune enhancement than other salts.
采用溶剂结晶法,以盐酸左旋咪唑和有机酸(抗坏血酸、酒石酸、柠檬酸和阿魏酸)为原料,分别制备了四种左旋咪唑有机酸盐。通过元素分析、紫外可见光谱、傅立叶变换红外光谱、ESI-MS、DSC-TGA、水中溶解度、熔点、旋光度和水中 pH 值对盐进行了表征。通过腹腔注射环磷酰胺建立免疫抑制小鼠模型,验证和比较盐酸左旋咪唑和左旋咪唑有机酸盐对免疫抑制小鼠免疫功能的影响。结果表明,阿魏酸左旋咪唑和酒石酸左旋咪唑在明显提高环磷酰胺诱导的免疫抑制小鼠血清 IgM 和 IgG 含量以及免疫器官指标的同时,IgG 含量和免疫器官指标的升高幅度均高于其他盐类。因此可以得出结论,阿魏酸左旋咪唑和酒石酸左旋咪唑比其他盐类更能有效增强免疫力。
