3-substituted-indolin-2-ones and azaindolin-2-ones have been synthesized and showed potential antiproliferative activity to cancer cell lines. The inhibition activities on VEGF-induced VEGFR phosphorylation were observed for selected 2-indolinones. Among the compounds synthesized, 5-fluoroindolin-2-one derivative 23 with a pyridone unit showed the most significant enzymatic and cellular activities. Flow cytometric
已经合成了三个系列的3-取代的吲哚啉-2-酮和氮杂吲哚-2-酮,它们显示出对癌细胞系潜在的抗增殖活性。对于选定的2-吲哚满酮,观察到了对VEGF诱导的VEGFR磷酸化的抑制活性。在合成的化合物中,具有吡啶酮单元的5-氟吲哚-2-酮衍生物23显示出最显着的酶和细胞活性。流式细胞仪分析表明23在剂量依赖性的G1期阻滞和凋亡中起着抑制HCT-116细胞增殖的作用。化合物23的结合方式使用FlexX算法预测与VEGFR-2复合。这里描述的是这些系列的化学和生物学测试,它们将指导新型2-吲哚酮抗肿瘤剂的设计和优化。
