18 novel dithiocarbamate derivatives were synthesized in order to investigate their inhibitory potency on acetylcholinesterase enzyme and antimicrobial activity. Structures of the synthesized compounds were elucidated by spectral data and elemental analyses. The synthesized compounds showed low enzyme inhibitory activity. However, they displayed good antimicrobial activity profile. Antibacterial activity of compounds4a,4e, and4p(MIC = 25 μg/mL) was equal to that of chloramphenicol againstKlebsiella pneumoniae(ATCC 700603) andEscherichia coli(ATCC 35218). Most of the compounds exhibited notable antifungal activity againstCandida albicans(ATCC 10231),Candida glabrata(ATCC 90030),Candida krusei(ATCC 6258), andCandida parapsilosis(ATCC 7330). Moreover, compound4a, which carries piperidin-1-yl substituent and dimethylthiocarbamoyl side chain as variable group, showed twofold better anticandidal effect against allCandidaspecies than reference drug ketoconazole.
为了研究二硫代氨基甲酸酯衍生物对乙酰胆碱酯酶的抑制能力和抗微生物活性,合成了18种新颖的二硫代氨基甲酸酯衍生物。合成化合物的结构通过光谱数据和元素分析得以阐明。合成的化合物显示出较低的酶抑制活性,但它们展现出良好的抗微生物活性。化合物4a、4e和4p的抗菌活性(最小抑菌浓度为25μg/mL)与氯霉素对Klebsiella pneumoniae(ATCC 700603)和大肠杆菌(ATCC 35218)的抗菌活性相当。大部分化合物对白念珠菌(ATCC 10231)、白念珠菌(ATCC 90030)、白念珠菌(ATCC 6258)和白念珠菌(ATCC 7330)表现出显著的抗真菌活性。此外,携带哌啶-1-基取代基和二甲硫代氨基甲酰侧链作为变量基团的化合物4a,在所有白念珠菌种类中显示出比参考药物酮康唑两倍更好的抗真菌效果。
