discovery of new drugs. In the current study, we have synthesized a series of new 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles by multicomponent reaction (MCR). Vanillin and isovanillin derivatives were reacted with benzil/pyridil and diverse amines and ammonium acetate in acetic acid at 50–110 °C for 24 h to afford respective imidazoles in 55–70% yields. The series of molecules were evaluated
基于咪唑的化合物是用于发现新药的新颖化学结构设计中的有吸引力的靶标。在当前的研究中,我们通过多组分反应(MCR)合成了一系列新的2,4,5-三取代和1,2,4,5-四取代的咪唑。香兰素和异香兰素衍生物在50-110°C的温度下,与苯甲酰/吡啶并与各种胺和乙酸铵在乙酸中反应24小时,从而以55-70%的产率提供各自的咪唑。评价了该系列分子对美国国家癌症研究所的60个人类癌细胞系的抗癌潜力。初步筛选突出了2,2'-(2-(3-(环戊氧基)-4-甲氧基苯基)-1-异丁基-1 H-咪唑-4,5-二基)二吡啶的抗癌潜力(NSC 771432)针对不同类型的癌细胞。A549细胞用体外以确定的动作模式NSC 771432对这些细胞的生长。该化合物抑制锚定独立生长和细胞迁移,并诱导细胞周期阻滞在G2 / M期。同样,A549细胞暴露于NSC 771432也会导致细胞衰老。
