A series of novel 3-(1H-benzo[d]imidazol-2-yl)-3,4-dihydro-2H-benzo[e][1,3] oxazine analogues synthesized through a two-step synthetic protocol. The structure of the compounds were established by interpretation 1H NMR, 13C NMR and Mass spectral data recorded after purification. All the title compounds 4a–k were screened for their in vitro anti-cancer activity against two breast cancer cell lines MCF
通过两步合成方案合成了一系列新型 3-(1H-苯并[d]咪唑-2-基)-3,4-二氢-2H-苯并[e][1,3]恶嗪类似物。通过解释1 H NMR、 13 C NMR 和纯化后记录的质谱数据确定了化合物的结构。使用阿霉素作为标准参考,筛选所有标题化合物4a-k对两种乳腺癌细胞系 MCF 7 和 MDA-MB-231 的体外抗癌活性。化合物4e对细胞系 MCF-7 和 MDA-MB-231 均表现出优异的活性,IC 50值分别为8.60 ± 0.75和6.30 ± 0.54 µM ,而多柔比星IC 50值为9.11 ± 0.54和8.47 ± 0.47 µM 。化合物4i还表现出良好的活性,针对 MCF-7 细胞的 IC 50值为9.85 ± 0.69 μM ,与多柔比星相当。化合物4g表现出与标准参考相当的最佳活性,针对 MDA-MB-231 细胞系的 IC 50值为8.52 ± 0.62
