摘要: Abstract β-Lactamases are serine and metallo-dependent enzymes produced by the bacteria in defense against β-lactam antibiotics. Production of class-A, class-B, class-C make use antibiotics ineffective certain cases. To overcome resistance to antibiotics, several β-lactamase inhibitors such as clavulanic acid, sulbactam, tazobactam widely used clinic combination with However, single point mutations within these have allowed inhibitory effect commercially approved inhibitors. Although available inhibitor/β-lactam antibiotic combinations effective class-A producing many extended spectrum (ESBL’s) they less expressing bacteria. circumvent this problem, based on modeling studies novel imidazole substituted 6-methylidene-penem derivatives were synthesized tested various isolates. The present paper deals synthesis structure–activity relationships (SAR) compounds.
