Nucleoside derivatives having a benzodithiol-2-yl (BDT) group were synthesized and examined for their anti-bovine viral diarrhea virus (BVDV) activities. Other substituents structurally similar to the BDT group such as 1,3-benzodioxol-2-yl, benzimidazol-2-yl and 1-oxo-benzodithiol-2-yl groups were not effective as the pharmacophore. The anti-BVDV assay revealed that 2'-O-BDT-guanosine and 2'-O-BDT-inosine
合成具有苯并二硫醇-2-基(BDT)基团的核苷衍生物,并检查其抗牛病毒性腹泻病毒(BVDV)的活性。结构上与BDT基团相似的其他取代基,例如1,3-苯并二恶唑-2-基,苯并咪唑-2-基和1-氧-苯并二硫醇-2-基均不能用作药效基团。抗BVDV分析表明,在本研究合成的核苷衍生物中,2'-O-BDT-鸟苷和2'-O-BDT-肌苷具有最强的抗BVDV活性。由于BVDV已被公认是人类丙型肝炎病毒(HCV)的替代物,因此BDT修饰的核苷可能成为寻找核苷型抗HCV药物(如病毒唑)的一类新型先导化合物。
