摘 要:目的设计并合成一系列硫胺素二硫化物类脑靶向药物载体。方法 2-(4-甲基噻唑-5-基)乙醇(Ⅰ)在不同溴代物的作用下,氮烷基化制成季铵盐(Ⅱ),该中间体经碱性开环后与烷基硫代硫酸钠(Ⅳ)反应即得到目标产物Ⅴ。结果与结论成功制备了9个含有不同取代基的硫胺素二硫化物;目标化合物经1HNMR和MS确证。OBJECTIVE To synthesize a series of thiamine disulfides as carriers for brain targeted delivery.METHODS 2-(4-methylthiazol-5-yl)ethanol(Ⅰ) was treated with different alkyl bromides,leading to the quaternary ammonium salt(Ⅱ) by alkyl group substitution an nitrogen subsequently,intermediate Ⅱ was hydrolyzed and reacted with thiosulfate salts(Ⅳ) to furnish target compounds Ⅴ.RESULTS Nine thiamine disulfides with different substituents were designed and synthesized.CONCLUSION The chemical structures of the target compounds were confirmed by 1HNMR and MS.
