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

A series of 3',4'-dihydro-1'H-spiro(indoline-3,2'-quinolin)-2-ones were prepared by the inverse-electron-demand aza-Diels-Alder reaction (Povarov reaction) of imines derived from isatin and substituted anilines, and the electron-rich alkenes trans-isoeugenol and 3,4-dihydro-2H-pyran. These compounds were assessed for in vitro antiplasmodial activity against drug-sensitive and drug-resistant forms of

Certain oxindole compounds have been found to be effective in experimentally induced autoimmune encephalitis and are therefore suggested for the preparation of a medicament for the prevention, treatment or amelioration of multiple sclerosis, or to delay the onset of or reduce the relapse rate in multiple sclerosis.
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
