Some pyridazine derivatives carrying urea, thiourea, and sulfonamide groups were synthesized and evaluated for their antimicrobial activity against gram-positive and gram-negative bacteria, and fungi by using broth microdilution. The structures of these new compounds were confirmed by ^1H-NMR, mass spectrum, and elemental analysis. The synthesized compounds exhibited generally promising inhibitory activity against S. aureus (MIC ranging from 2 to 4 \mu g/mL) and E. coli (MIC ranging from 4 to 16 \mu g/mL). Moreover, all compounds showed antifungal activity against both C. albicans and C. parapsilosis, with a MIC value of 8 \mu g/mL.
通过肉汤微量稀释法,对部分吡嗪衍生物(含尿素、硫脲和磺酰胺基团)的抗菌活性进行了合成和评估,包括对革兰氏阳性和革兰氏阴性细菌以及真菌的抗菌活性。通过^1H-NMR、质谱和元素分析确认了这些新化合物的结构。合成化合物对金黄色葡萄球菌(MIC为2至4微克/毫升)和大肠杆菌(MIC为4至16微克/毫升)表现出普遍有效的抑制活性。此外,所有化合物对白色念珠菌和副假丝酵母菌均表现出抗真菌活性,MIC值为8微克/毫升。
