A series of new pyrrole derivatives, pyrrolo[2,3-d]pyrimidine derivatives, pyrrolotriazolopyrimidines and pyrrolotetrazolopyrimidines were synthesized. The evaluation of their antimicrobial activities against Staphylococcus aureus, Escherichia coli, and Candida albicans were carried out. Pyrrolo[2,3-d]pyrimidines 3a–d, 7a,e, 11d exhibited excellent activity against C. albicans with MIC 0.31–0.62 mg/mL
合成了一系列新的吡咯衍生物,吡咯并[2,3- d ]嘧啶衍生物,吡咯并三唑并嘧啶和吡咯并四唑并嘧啶。评估了它们对金黄色葡萄球菌,大肠杆菌和白色念珠菌的抗菌活性。吡咯并[2,3- d ]嘧啶3a-d,7a,e,11d表现出对白色念珠菌的优异活性,MIC为0.31-0.62 mg / mL。这些化合物显示出比标准药物(氟康唑,MIC 1.5 mg / mL)更好的抗真菌活性。此外,吡咯并[2,3- d ]嘧啶与标准药物(氨苄青霉素,MIC为0.62 mg / mL)相比,图3b,c,7e对MIC为0.31 mg / mL的金黄色葡萄球菌表现出最佳的活性。发现其余化合物对细菌和真菌无活性。
