New amidine and benzene sulfonamide derivatives were developed and structures of the new products were confirmed by elemental and spectral analysis (FT-IR, ESI-MS,1HNMR, and13CNMR). In vitro, developed compounds were screened for their antibacterial and antifungal activities against medically important bacterial strains, namely,S. aureus, B. subtilis, andE. coli, and fungi, namely,A. flavus, A. parasiticus, andA.sp. The antibacterial and antifungal activities have been determined by measuring MIC values (μg/mL) and zone of inhibitions (mm). Among the tested compounds, it was found that compounds3b,9a, and9bhave most potent activity againstS. aureus, A. flavus, and A. parasiticus, respectively, and were found to be more active than sulfamethoxazole and itraconazole with MIC values 40 μg/mL. In contrast, all the compounds were totally inactive against theA.sp. except10band15bto show activity to some extent.
新的胍和苯磺酰胺衍生物已经研发,并通过元素分析和光谱分析(FT-IR、ESI-MS、1HNMR和13CNMR)确认了新产品的结构。在体外实验中,开发的化合物针对医学上重要的细菌菌株,即金黄色葡萄球菌、枯草芽孢杆菌和大肠杆菌,以及真菌,即黄曲霉、寄生曲霉和某种真菌,进行了抗菌和抗真菌活性筛选。抗菌和抗真菌活性是通过测定MIC值(μg/mL)和抑菌圈直径(mm)来确定的。在测试的化合物中,发现化合物3b、9a和9b对金黄色葡萄球菌、黄曲霉和寄生曲霉具有最强的活性,分别比磺胺甲噁唑和伊曲康唑更活跃,MIC值为40μg/mL。相反,所有化合物对某种真菌完全无活性,除了10b和15b在一定程度上显示出活性。
