Twenty novel 1,2,3-triazole noscapine derivatives were synthesized starting from noscapine by consecutive N-demethylation, reduction of lactone ring, N-propargylation and Huisgen 1,3-dipolar cycloaddition reaction. In order to select the most promising molecules to subject to further biophysical and biological evaluation, a molecular docking analysis round was performed using noscapine as the reference
通过连续的N-去甲基化,内酯环的还原,N的合成,从Noscapine合成了二十种新的1,2,3-三唑Noscapine衍生物-炔丙基化和Huisgen 1,3-偶极环加成反应。为了选择最有希望的分子进行进一步的生物物理和生物学评估,使用Noscapine作为参考化合物进行了分子对接分析。然后将对接的分子预测的结合亲和力比Noscapine更好,然后对MCF7细胞株进行MTT分析。获得的结果表明,与Noscapine相比,所有选择的三唑衍生物在48小时内的细胞活力均显着低于Noscapine,范围为20μM。为了使生物学活性与结合微管蛋白的能力相关联,采用了表面等离子体共振(SPR)测定法。化合物8a,8h,9c,9f和9j能够结合微管蛋白,其亲和常数值在纳摩尔范围内,并且与去甲可卡因相比更高。综合计算预测和实验评估,确定了两个有前途的化合物(8h和9c),其相关的细胞毒性被认为与微管蛋白结
