075-1.547 µM versus wild EGFRWT and 63.70-87.34 nM versus the mutant type. Erlotinib was used as a standard reference with IC50 values of 0.0656 µM and 59.56 nM versus both types. Finally, the molecular docking study of most potent quinoxaline derivatives exhibited a good binding inside the active site of EGFR (1M17), with binding energy ranged between (-15.86 to -16.97) compared to Erlotinib (-17.84)
合成了一系列新的喹喔啉衍生物,并针对(HepG-2,HCT-116和MCF-7)细胞系进行了药理学评估。发现七种化合物对所检查的细胞系具有最高活性,IC 50值在(7.57至28.44 µM)之间。为了进一步分析其在MCF-7细胞中的凋亡潜力,最活跃的3a,3b,6、7b,7c,7d和7f成员已被选择。有趣的是,它发现Bcl-2水平相对于对照降低了1.95–3.99倍,BAX水平升高了7.2-10.6倍。与未处理的细胞相比,它们还将活性Caspase-3水平提高了5.77-10.69倍。用这些化合物处理WI38细胞,以估计这些化合物在非致瘤细胞中的细胞毒性水平,它们显示出更高的IC 50值(142.21-335.03μM),表明对正常细胞的毒性作用可能较小。对最有前途的化合物3a,6、7b和7d机理的进一步研究表明,它增加了凋亡细胞,并诱导了前G1和G2 / M期的细胞周期停滞。此外,野生EGFR
