Aspergillus niger, and Aspergillus flavus). Whereas compound 6a exhibited the highest antibacterial activity against Gram positive and Gram negative bacteria, 13b displayed the strongest antifungal activity against all fungal strains, reaching as high as 30 mm. Finally, 15a,b,d were subjected to in vitro testing of antiviral activity against hepatitis A virus (HAV), human herpes simplex virus 1 (HSV1), and Coxsackie
一系列38种新型咪唑烷亚氨基硫酮(6a – g,10a – h,13a,b,15a – d和16a),5-硫代氧杂咪唑烷-2,4-二酮(7a – d,11a – e,14a,b,和16B),和双- imidazolidineiminothiones(17 - 20),在各种氟化芳族取代基ñ - (1)和ñ-(3)的制备产率为75-85%。由氟化的N-芳基氰基硫代甲酰苯胺和取代的芳族异氰酸酯,以及氟化的芳族异氰酸酯与氟化的和非氟化的芳族N-芳基氰基硫代甲酰苯胺反应,合成咪唑烷亚氨基硫酮。所选产物的随后水解产生了相应的5-硫代氧杂咪唑烷-2,4-二酮。初步筛选了几种针对Ehrlich腹水癌细胞(EAC)的化合物,结果表明6f和16a的活性最高(分别为90%和80%抑制)。进一步评估针对其他肿瘤细胞系的细胞毒性,得出IC 50值为0.67至3.83μg/ mL,其中化合物15a和16a对所有细胞
