摘要/Abstract

以咔唑和4-氰基氯化苄为初始原料，经多步反应合成出了一系列新型含咔唑基团的酰腙衍生物6，并利用IR、¹H NMR、¹³C NMR和元素分析对其进行了结构表征.对目标化合物进行了Cdc25B/PTP1B抑制活性评价，结果显示，目标化合物6对Cdc25B/PTP1B均具有较高的抑制活性，其中4-[（咔唑-9-基）甲基]-N'-（2-羟基-1-萘亚甲基）苯甲酰肼（6g）对Cdc25B和PTP1B的抑制活性最高，IC₅₀值分别为（2.16±0.38）和（1.06±0.23）μg/mL.对化合物6g进行分子对接的研究结果表明，6g能与Cdc25B/PTP1B酶形成稳定的复合物，形成氢键和疏水等相互作用.

A series of novel acylhydrazone derivatives 6 containing carbazole moity were synthesized by carbazole and 4-cyanobenzyl chloride as starting materials via multi-step reactions. Their structures were characterized by IR, ¹H NMR, ¹³C NMR spectra and elemental analysis. All synthesized target compounds were evaluated for the inhibitory activities against Cdc25B and PTP1B. The results show that the target compounds display significant inhibitory activities against Cdc25B/PTP1B. Among them, compound 4-((carbazol-9-yl)methyl)-N'-(2-hydroxy-1-naphthalenylmethylene)benzoyl hydrazide (6g) had the highest inhibitory activities against Cdc25B and PTP1B with IC₅₀ values of (2.16±0.38) and (1.06±0.23) μg/mL, respectively. The molecular docking results indicated that the hydrogen bond and hydrophobic interaction formed between compound 6g and Cdc25B/PTP1B enzyme.
Key words: acylhydrazone, carbazole, synthesis, Cdc25B and PTP1B inhibitor, molecular docking
