A total of 31 of thiourea derivatives was prepared reacting 3-(trifluoromethyl)aniline and commercial aliphatic and aromatic isothiocyanates. The yields varied from 35% to 82%. All compounds were evaluated in vitro for antimicrobial activity. Derivatives 3, 5, 6, 9, 15, 24 and 27 showed the highest inhibition against Gram-positive cocci (standard and hospital strains). The observed MIC values were
制备了总共31种使3-(三氟甲基)苯胺与市售脂族和芳族异硫氰酸酯反应的硫脲衍生物。产率从35%到82%不等。在体外评估所有化合物的抗微生物活性。衍生物3,5,6,9,15,24和27显示出对革兰氏阳性球菌(标准和医院的菌株)的最高抑制。观察到的MIC值在0.25–16μg/ ml的范围内。研究了硫脲5和15对从金黄色葡萄球菌分离的拓扑异构酶IV的抑制活性。产品5和15有效抑制了耐甲氧西林和表皮葡萄球菌的标准菌株的生物膜形成。此外,评估了所有获得的硫脲对大量DNA和RNA病毒的细胞毒性和抗病毒活性。化合物5,6,8-12,15导致细胞毒性对MT-4细胞(CC 50 ≤10μM)。
