formula using this technique. All of the synthesized compounds were screened for their antibacterial, antifungal and antiviral activities. Five compounds (12, 13, 14, 16 and 19) exerted a modest antifungal activity against the strains evaluated. Derivative 14 showed fungicidal activity against Candida glabrata at 173.8 μM and saccharide unit contributed to the increase of the antifungal potential against
摘要 合成了一系列新的糖基化酰腙,所有化学结构均通过高分辨率质谱 (HRMS)、1H 和 13C 核磁共振 (1H-NMR; 13C-NMR) 和傅里叶变换红外 (FTIR) 光谱方法确认。在 HRMS 分析中观察到的计算值和实测值之间的质量准确度接近或低于 5 ppm,这对于使用该技术提出分子式是可以接受的。筛选所有合成的化合物的抗菌、抗真菌和抗病毒活性。五种化合物(12、13、14、16 和 19)对所评估的菌株具有适度的抗真菌活性。衍生物 14 在 173.8 μM 时显示出对光滑念珠菌的杀真菌活性,并且糖单位有助于增加对该菌株的抗真菌潜力。
