A new series of pyrrolizine derivatives 4–8c were synthesized, their structures were confirmed by spectral and elemental analyses. Cytotoxic activity of these compounds was evaluated against breast (MCF7), colon (HCT116) and liver (HEPG2) cancer cell lines using sulphorhodamine-B (SRB) assay method. All the tested compounds showed highly potent activity against MCF7 cell line with IC50 range equal
合成了一系列新的吡咯嗪衍生物4-8c,并通过光谱和元素分析证实了它们的结构。使用磺基罗丹明B(SRB)分析方法评估了这些化合物对乳腺癌(MCF7),结肠癌(HCT116)和肝癌(HEPG2)的细胞毒活性。所有测试的化合物均显示出对MCF7细胞系的强效活性,IC 50范围为8–194 nM / ml,化合物8c是活性最高的化合物(IC 50 = 8.6 nM / ml)。8b是HCT116和HEPG-2癌细胞系中最好的活性化合物。它的IC 50分别为26.5和12.3 nM / ml。对EGFR酪氨酸激酶的ATP结合位点进行对接研究,以预测它们的得分和与氨基酸的结合方式,此外,还评估了这些化合物对EGFR-TKs的抑制活性;化合物8c和8b的抑菌百分率在40.4至97.6之间,分别显示出97.6%和88.4%的抑菌活性。
