c-Src is considered one of the most studied approaches to cancer treatment, with several heterocyclic compounds approved during the last 15 years as chemotherapeutic agents. Starting from the biologicalevaluation of an in-house collection of small molecules, indolinone was selected as the most promising scaffold. In this work, several functionalised indolinones were synthesised and their inhibitory potency
A series of 6-chloro-3-oxindole derivatives 1–25 were synthesized in high yields by the reaction of 6-chlorooxindole with different aromatic aldehydes in the presence of piperidine. All the synthesized compounds were isolated with E configuration. The structures were confirmed using spectroscopic techniques, including 1H NMR and EIMS. These compounds showed varying degree of yeast α-glucosidase inhibition
在哌啶存在下,通过6-氯代吲哚与不同的芳族醛的反应,可以高收率合成一系列6-氯-3-氧吲哚衍生物1 – 25。用E构型分离所有合成的化合物。使用包括1 H NMR和EIMS在内的光谱技术确认了结构。这些化合物显示出不同程度的酵母α-葡萄糖苷酶抑制作用,并且发现有七种是该酶的有效抑制剂。化合物2,3,4,5,6,23,和25显示出IC 50值2.71±0.007,11.41±0.005,37.93±0.002,15.19±0.004,24.71±0.007,17.33±0.001,和14.2±0.002μM,分别作为相对于标准阿卡波糖(IC 50,38.25±0.12μM)。对接研究有助于发现酶与活性化合物之间的相互作用。这项研究的结果是,已发现羟吲哚是一类新的α-葡萄糖苷酶抑制剂,但尚未见报道。
