Additionally, it displayed inhibition in cell based assay measuring phosphorylated-FAK (IC50 = 32.72 nM). Inhibition of FAK enzyme led to a significant increase in the level of active caspase-3, compared to control (11.35 folds), accumulation of cells in pre-G1 phase and annexin-V and propidium iodide staining in addition to cell cycle arrest at G2/M phase indicating that cell death proceeded through
根据基于片段的设计策略,合成了一系列新型的苯并三唑N-酰基芳基hydr杂化物。通过NCI(美国)评估了所有合成的化合物对60种人类肿瘤细胞的抗癌活性。三种化合物:3d,3e,3f,3o和3q在低浓度下显示出显着的有效抗癌活性。化合物3q对34种肿瘤细胞系表现出最突出的广谱抗癌活性,平均生长抑制百分比为45.80%。它对结肠HT-29细胞株发挥最高的效力,对细胞生长的抑制为86.86%。所有白血病细胞系对化合物3q高度敏感。此外,化合物3q对属于MDA-MB-435的黑色素瘤显示出致命的活性。化合物3e对白血病CCRF-CEM和HL-60(TB)细胞系表现出最高的抗癌活性,对细胞生长的抑制作用分别为86.69%和86.42%。而且,它对卵巢OVCAR-3癌细胞系发挥了显着的效力,对细胞生长的抑制作用为78.24%。通过确定针对最敏感癌细胞系的IC 50值,进一步研究了四种化合物:3d,3e,
