为了继续进行新型生物活性剂的合成,我们从吲哚/羟吲哚(29种化合物)合成了两组三唑连接的糖缀合物,并通过IR(红外光谱),1 H NMR(核磁共振)进行了进一步表征,13 C NMR和质谱分析。评估了新合成的目标化合物对DU145(前列腺癌),HeLa(宫颈癌),A549(肺癌)和MCF-7(乳腺癌)细胞系的初步体外抗癌活性。在磺基罗丹明B(SRB)分析中,结果表明化合物5f(吲哚衍生物)和E -9b(羟吲哚衍生物)对DU145细胞显示出显着的细胞毒活性。此外,集落形成测定法(软琼脂测定法)表明化合物5f和E -9b可以抑制DU145细胞的生长和增殖。在DU145细胞中评估了活性最高的细胞毒性化合物5f和E -9b对细胞周期分布的影响,该细胞在亚G1期表现出细胞周期停滞。接下来,化合物5f和E -9b对DU145细胞中的半胱天冬酶激活进行了测试,结果表明这些化合物具有通过内在途径诱导细胞凋

Glycogen synthase kinase 3β (GSK-3β) is a widely investigated molecular target for numerous diseases including Alzheimer's disease, cancer, and diabetes mellitus. Inhibition of GSK-3β activity has become an attractive approach for treatment of diabetes and cancer. We report the discovery of novel GSK-3β inhibitors of 3-arylidene-2-oxindole scaffold with promising activity. The most potent compound

developed to provide rapid access to 3-alkenyl-oxindoles from α-halo-anilides. This one-pot microwave accelerated process proceeds with catalytic palladium(II) acetate or tetrakis(triphenylphosphine)palladium, and has been used to prepare a range of adducts derivedfrom aromatic, heteroaromatic and aliphatic aldehydes. The procedures can be used to prepare N-unprotected oxindoles directly and the applicability
reusable catalyst for the C3-selective alkenylation of oxindole with aldehydes under solvent-free conditions. This catalytic method is generally applicable to different aromatic and aliphatic aldehydes, giving 3-alkyledene-oxindoles in high yields (87%–99%) and high stereoselectivities (79%–93% to E-isomers). This is the first example of the catalytic synthesis of 3-alkenyl-oxindoles from oxindole and
