Abstract A set of quinazolinones synthesized by the aid of L-norephedrine was assembled to generate novel analogues as potential anticancer and radiosensitizing agents. The new compounds were evaluated for their cytotoxic activity against MDA-MB-231, MCF-7, HepG-2, HCT-116 cancer cell lines and EGFR inhibitory activity. The most active compounds 5 and 6 were screened against MCF-10A normal cell line
摘要 在 L-
去甲麻黄碱的帮助下合成了一组
喹唑啉酮类化合物,以产生新的类似物作为潜在的抗癌剂和放射增敏剂。评估了这些新化合物对
MDA-MB-231、MCF-7、HepG-2、HCT-116 癌
细胞系的细胞毒活性和
EGFR 抑制活性。针对 MCF-10A 正常
细胞系筛选出最活跃的化合物5和6 ,并显示出较低的毒性作用。他们证明了它们对
MDA-MB-231 乳腺癌
细胞系具有高选择性的相对安全性。对5和6的放射增敏活性的测量表明,它们可以在暴露于单剂量 8 Gy 伽马辐射后使肿瘤细胞敏感。化合物5能够诱导细胞凋亡并将细胞周期停滞在G2-M期。在
EGFR 的活性位点进行5和6的分子对接以深入了解与关键
氨基酸的结合相互作用。
