Discovery and biological evaluation of nitrofuranyl-pyrazolopyrimidine hybrid conjugates as potent antimicrobial agents targeting and methicillin-resistant .

Nitrofuran and pyrazolopyrimidine-based compounds possess a broad antimicrobial spectrum including Gram-positive and Gram-negative bacteria. In the present work, a series of conjugates of these scaffolds was synthesized and evaluated for antimicrobial activity against and methicillin-resistant (MRSA). Many compounds showed MIC values of ≤2 μg ml, with compound 35 demonstrating excellent activity (MICs: 0.
