the corresponding alkyl- and aryl-urea derivatives. All the prepared urea compounds have been elucidated by FTIR, NMR, and elemental analysis. The compounds 1 and 3 were confirmed by single-crystal X-ray diffraction. The 4-tolylsulfonyl isocyanate reacted with the aryl amines 1, 2, 3, and 2,4-dichloroaniline to afford the corresponding sulfonylurea derivatives 5–8. Likewise, the reaction of the isocyanates
烷基或芳基异氰酸酯与一些伯胺在乙腈中在室温下反应得到相应的烷基-和芳基-脲衍生物。所制备的尿素化合物均经FTIR、NMR和元素分析鉴定。化合物1和3经单晶 X 射线衍射证实。4-甲苯磺酰基异氰酸酯与芳胺反应1,2,3,和2,4-二氯苯胺,得到相应的磺酰脲衍生物5-8。同样,异氰酸酯与 2,4-二氯苯胺、5-甲基异恶唑-3-胺和 2-氨基噻唑衍生物反应得到相应的脲衍生物9-17. 所有制备的化合物5-17都作为抗微生物和抗 HepG2 药物进行了体外测试。此外,还讨论了分析 TP53-exon4 和 TP53-exon7 的基因表达、DNA 损伤值和 DNA 片段化百分比。化合物5和8 分别记录了对测试微生物菌株的最高活性,对白色念珠菌(50 mm) 和B. mycoides (40 mm) 的活性最大。化合物5以 0.0489 µM 的 MIC 水平抑制大肠杆菌、金黄色葡萄球菌和白色念珠菌
