A series of novel unsymmetrically N,N'-substituted ureas were synthesized from dehydroabietic acid and their structures were characterized by IR, 1H-NMR, 13C-NMR spectroscopy and single crystal X-ray diffraction. Three six-membered rings of urea 4c exhibited plane, half-chair and chair configurations, respectively. Their cytotoxicity activities against SMMC7721 liver cancer cells were evaluated by
由脱氢松香酸合成了一系列新型的不对称N,N′-取代的脲,并通过IR,1H-NMR,13C-NMR和单晶X射线衍射对它们的结构进行了表征。尿素4c的三个六元环分别表现出平面,半椅和椅构型。通过MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物)方法评估它们对SMMC7721肝癌细胞的细胞毒性活性。结果表明标题化合物对SMMC7721细胞表现出高度有效的细胞毒性活性。它们的IC50值在8.8和14.2 micromol / l之间。N'取代基的变化对尿素的细胞毒性活性影响不大,
