derivatives were designed and synthesized. The biological activities of these derivatives were then evaluated as potential antitumour agents. These compounds were assayed for growth-inhibitory activity against HCT116, MCF-7 and HepG2 cell lines in vitro. The IC50 values of compounds A1 and A7 against the cancer cells were 0.06–3.64 μM and 0.04–9.80 μM, respectively. Their antiproliferative activities were
设计并合成了一系列新型的苯并咪唑-2-取代的苯基或吡啶丙基乙烯酮衍生物。然后评估这些衍生物的生物活性作为潜在的抗肿瘤剂。在体外测定了这些化合物对HCT116,MCF-7和HepG2细胞系的生长抑制活性。化合物A 1和A 7对癌细胞的IC 50值分别为0.06-3.64μM和0.04-9.80μM。它们的抗增殖活性明显优于5-氟尿嘧啶(IC 50:56.96–174.50μM),并且接近于紫杉醇(IC 50)。:0.026–1.53μM)。这些衍生物的活性比查耳酮类似物(licochalcone A)的其他报道的结构高出100倍以上。初步的机理研究表明,这些化合物可抑制p53-MDM2的结合。在患有结肠癌HCT116细胞的BALB / c小鼠中,化合物A 1,A 7和A 9有效抑制肿瘤生长。该小组服用了200 mg / kg的化合物A 7在高剂量下显示出74.6%的肿瘤生长抑制作用,没有毒性迹象,这与12
