well as xylylenediamines were synthesized and investigated for their cytotoxic activities. The results revealed that most analogs displayed cytotoxicity against HepG2 and MOLT-3 cell lines. The bis-thiourea derivatives 23 and 24 exhibited higher inhibitory potency against HepG2 cell than the reference drug, etoposide. 1,1′-(1,3-phenylenebis(methylene))bis(3-(4-chlorophenyl)thiourea) 24 was shown to be
简化1,3-二取代的脲衍生物(11 - 24)的苯乙胺,homoveratylamines,2- pyridylethylamines,2- picolylamines以及亚二甲苯基二胺的合成和研究了它们的细胞毒活性。结果表明,大多数类似物显示出对HepG2和MOLT-3细胞系的细胞毒性。与参考药物依托泊苷相比,双硫脲衍生物23和24对HepG2细胞的抑制作用更高。1,1'-(1,3-亚苯基双(亚甲基))双(3-(4-氯苯基)硫脲)24被证明是针对MOLT-3细胞系最有效的细胞毒性化合物,IC 50值为1.62μM。QSAR研究表明,具有高电离潜力的化合物对HuCCA-1细胞系显示出高细胞毒性。此外,具有二甲氧基苯基的衍生物具有高的径向分布功能,并且对A549细胞系具有相应的高细胞毒性。而且,类似物23和24具有较低的E HOMO值(最大占据分子轨道能量的能量)以及对HepG2细胞系的高细
