AbstractIn this work, synthesis and evaluation of pyrazino[1,2‐a]indole‐1,4‐dione‐indole‐2‐phenylacetamides 6 a–k as new synthetic anti‐diabetes agents were presented. These compounds were synthesized by a four‐component Ugi reaction without metal catalyst. All synthesized compounds were evaluated against α‐glucosidase and α‐amylase as two important targets in the treatment of diabetes. Approximately, all new compounds 6 a–k were more potent than positive control acarbose against these studied enzymes. The obtained potent compounds against the target enzymes were docked in the active site of the related enzyme. Docking study showed that our new potent compounds as well interacted with key residues of the target enzyme.
摘要 在这项工作中,介绍了吡嗪并[1,2-a]吲哚-1,4-二酮-吲哚-2-苯乙酰胺 6 a-k 作为新的合成抗糖尿病药物的合成和评估。这些化合物是在不使用金属催化剂的情况下通过四组分乌基反应合成的。所有合成化合物都针对治疗糖尿病的两个重要靶点 α-葡萄糖苷酶和 α-淀粉酶进行了评估。与阳性对照阿卡波糖相比,所有新化合物 6 a-k 对这些研究酶的作用都更强。所获得的对靶酶有效的化合物与相关酶的活性位点进行了对接。对接研究表明,新的强效化合物与目标酶的关键残基也有相互作用。
