Chalcone and chromene motifs are synthetic or naturally occurring scaffolds with significant cytotoxic profile. Two types of novel regioisomeric chromene-chalcone hybrids, namely 1-(6-chloro or 6-methoxy-2H-chromen-3-yl)-3-phenylprop-2-en-1-one (Type A) and 3-(6-chloro or 6-methoxy-2H-chromen-3-yl)-1-phenylprop-2-en-1-one (Type B), both with different substituents on the phenyl ring attached to propenone linkage, have been evaluated for their cytotoxic activity against breast cancer cell lines (MCF-7 and MDA-MB-231). The results indicate that type A of chromene-chalcones demonstrated better cytotoxic profile than type B especially in MDA-MB-231 cell line. In addition, the growth inhibitory activity of most of the target compounds is higher than Etoposide as a reference drug. QSAR analysis of these novel compounds demonstrated that topological and geometrical parameters are among the important descriptors that influence the cytotoxic activity profile of compounds.
查尔克酮和色烯基是合成或天然存在的框架,具有显著的细胞毒性特征。两种新型区域异构体色烯-查尔克酮杂交物,即1-(6-氯或6-甲氧基-2H-色烯-3-基)-3-苯基丙-2-烯-1-酮(类型A)和3-(6-氯或6-甲氧基-2H-色烯-3-基)-1-苯基丙-2-烯-1-酮(类型B),两者在连接端的苯环上具有不同的取代基,已被评估其对乳腺癌细胞系(MCF-7和MDA-MB-231)的细胞毒性活性。结果表明,类型A的色烯-查尔克酮在MDA-MB-231细胞系中表现出比类型B更好的细胞毒性特征。此外,大多数目标化合物的生长抑制活性高于作为参考药物的依托泊苷。对这些新化合物的QSAR分析表明,拓扑和几何参数是影响化合物细胞毒性活性特征的重要描述符之一。
