reaction of dicarboximide with ethyl bromoacetate. All obtained derivatives were analysed by 1H and 13C NMR spectra, and for one compound, the X-ray crystallography was done. Antimicrobial, antiviral and in vitro evaluations of cytotoxicity were examined. According to the preliminary antiviral screening, compounds 3 and 4 presented the antiviral activity against HSV-1 and CVB3. Additionally, compound 3 shows
在这项研究中,我们描述了硫代氨基脲,二羧酰亚胺,1,2,4-三唑-5-硫酮和4-氧代-1,3-噻唑烷的衍生物的合成。得到两种不同的二羧酸酐与4-取代的-3-硫代氨基脲反应,得到了硫代氨基脲和二羧酰亚胺的衍生物。接下来,使用二羧酰亚胺衍生物在碱性介质中的环化反应制备1,2,4-三唑-5-硫酮。通过二羧酰亚胺与溴乙酸乙酯反应合成了4-氧代-1,3-噻唑烷。通过1 H和13分析所有获得的衍生物1 H NMR光谱,对于一种化合物,进行X射线晶体学分析。检查了细胞毒性的抗微生物,抗病毒和体外评估。根据初步的抗病毒筛选,化合物3和4对HSV-1和CVB3具有抗病毒活性。另外,化合物3显示出对人上皮细胞FaDu的选择性体外毒性作用,而不影响正常动物细胞系(Vero)。相同的衍生物3和4还显示出对参考微生物的广泛抗菌活性,并显示出抗菌和抗真菌的潜在活性。
