Description
技术领域
本发明涉及药物合成领域,具体涉及一种新型碳糖苷及其制备方法。
背景技术
碳糖苷由于碳-碳键取代了碳-氧、碳-氮、碳-硫等不稳定化学键,使得碳糖苷稳定性大大得到提高,特别是在水解酶、酸、抗代谢方面。碳糖苷不仅是一类糖苷酶抑制剂,同时,碳糖苷以糖为载体,更易在体内发挥作用,还可以大大降低其他类型抑制剂的毒副作用,从而有望成为高效低毒的药物。碳糖苷的药理活性十分广泛,有抗肿瘤、抗菌、抗病毒和促进细胞分裂以及免疫调节作用等,是一类潜在药物。目前碳糖苷多围绕芳基、烯基和未官能团化的烷基,通过碳-碳键直接与糖基相连,不能更好的模拟自然界的氧/氮/硫苷,生物学活性较低,限制了其成药性开发进度。新型碳糖苷通过引入亚甲基羟基,能够更好的模拟自然界的氧/氮/硫苷与特定靶点的结合,同时兼顾碳糖苷稳定性等优点,能够潜在的提高其生物活性,因此开发这一类新型糖苷具有十分重要意义。
