pyrazolopyrimidines 5a–f had been constructed. The newly synthesized compounds were assessed for their antimicrobial activity towards E. coli and P. aeruginosa (gram –ve bacteria), B. subtilis and S. aureus (gram +ve bacteria) and A. flavus and C. albicans (representative of fungi). The pyrazolylpyrimidine-2,4-dione derivative 5b is the most active candidate against B. subtilis (MIC=60 μg/mL) and P. aeruginosa (MIC=45 μg/mL)
构建了新系列的吡唑4a - c和吡唑并嘧啶5a - f 。评估了新合成的化合物对大肠杆菌和铜绿假单胞菌(革兰氏 -ve 细菌)、枯草芽孢杆菌和金黄色葡萄球菌(革兰氏 +ve 细菌)以及黄曲霉和白色念珠菌(真菌的代表)的抗菌活性). pyrazolylpyrimidine-2,4-dione 衍生物5b是抗枯草芽孢杆菌(MIC=60 μg/mL) 和铜绿假单胞菌(MIC=45 μg/mL)最活跃的候选物。关于抗真菌潜力,化合物5f对A. flavus最有效(MIC=33 μg/mL)。类似地,相对于两性霉素 B(MIC = 60 μg/mL),化合物 5c 显示出对白色念珠菌(MIC = 36 μg/mL)的强抗真菌活性。最后,新化合物已停靠在二氢叶酸合酶 (DHPS) 内,以表明这些化合物的结合模式。
