A series of sulfonyl-N-hydroxyguanidine derivatives was designed and synthesized for cytotoxic evaluation as potential anticancer agents on the basis of the lead compound LY-181984. Replacement of the ureido moiety of the lead compound with hydroxyguanidine provided a stable cytotoxic agent. The conformation of sulfonyl-N-hydroxyguanidine derivatives, such as N-(4-chlorophenyl)-N'-[(benzo[2,1,3]th
以铅化合物LY-181984为基础,设计合成了一系列磺酰基-N-羟基胍衍生物,作为潜在的抗癌药进行细胞毒性评价。用羟基胍代替前导化合物的脲基部分提供了稳定的细胞毒剂。磺酰基-N-羟基胍衍生物的构象,例如N-(4-氯苯基)-N'-[(苯并[2,1,3]噻二唑-4-基)磺酰基] -N“-羟基胍(4g),使用HMBC NMR,理论计算和X射线晶体学研究表明,这两个芳环堆叠在一起,并评估了这些衍生物对5种人类肿瘤细胞系的体外细胞毒性,包括HepG2,TSGH 8302,COLO 205,KB和MOLT -4。衍生化合物对人肿瘤细胞系的细胞毒活性等于或大于先导化合物。N-(4-氯苯基)-N'-[[3,5-二氯-4-(4-硝基苯氧基)苯基]磺酰基]-N“-羟基胍(4n)和N-(4-氯苯基)-N'- [[3,5-二氯-4-(2-氯-4-硝基苯氧基)苯基]磺酰基] -N”-羟基胍(4o)对实体瘤细胞系表现
