制备方法与用途

简介

2,5-二氨基-4,6-二羟基吡啶是有机化工中间体,可用于合成2-氨基-4,6-二氯-5-甲酰氨基嘧啶。该化合物广泛应用于合成艾滋病防治药物,目前已有数十个品种的治疗艾滋病药物通过其合成。由这类化合物制造的新一代抗艾滋病药物具有独特的功能,被视为一种很有发展前途的药物和合成中间体。

艾滋病是由人类免疫缺陷病毒(HIV)感染导致的人体防御机能缺陷(尤其是细胞介导的免疫机能缺陷),从而易发生机会性感染和肿瘤的一种临床综合征。

制备

以丙二酸二乙酯(32g,0.2mol)、盐酸胍(9.6g,0.1mol)、乙醇钠(27.2g,0.4mol)及150mL乙醇为原料,在加热回流条件下反应。所得固体与亚硝酸钠(13.8g,0.2mol),在水(200mL)、乙醇(170mL)和乙酸(16mL)的溶液中于25℃下反应24小时。反应后得到的固体在连二亚硫酸钠(43.5g,0.25mol)及200mL水的存在下回流反应8小时,最终生成2,5-二氨基-4,6-二羟基嘧啶,产率为48%。

    A series of methyl 2-substituted purine 8-carbamates was prepared and evaluated for antifilarial activity. These purines were synthesized as aza congeners of benzimidazole carbamates which have shown significant anthelmintic activity to determine the effect that this modification might have on anthelmintic activity. The compounds were tested against the filarial infection, B. pahangi, in jirds. None
