The novel pyrimidine carboacyclonucleoside analogues containing propargylated aryl side chains were synthesized via palladium-catalyzed cross-coupling reactions as a key step. The synthesized compounds were screened for their antibacterial activity against four microorganisms: Staphylococcus aureus (CIP 53.154; Gram positive), Enterococcus hirae (CIP 58.55; Gram positive), Pseudomonas aeruginosa (CIP A22; Gram negative), Escherichia coli (CIP 54.8; Gram negative). Some of the prepared products showed promising antibacterial activity against the nosocomial E. hirae.
通过钯催化的交叉偶联反应合成了含有丙炔基芳基侧链的新型嘧啶类碳酰环核苷类似物,作为关键步骤。合成的化合物被筛选其抗菌活性,针对四种微生物:金黄色葡萄球菌(CIP 53.154;革兰氏阳性)、海藻链球菌(CIP 58.55;革兰氏阳性)、铜绿假单胞菌(CIP A22;革兰氏阴性)、大肠杆菌(CIP 54.8;革兰氏阴性)。一些制备的产物表现出对院内感染性海藻链球菌有良好的抗菌活性。
