Structure Based Inhibitor Discovery Targeting Multiple Β-Lactamases Involved In Antibiotic Resistance, Afroza Akhtar

USF Tampa Graduate Theses and Dissertations

Emergence of antibiotic resistance severely threatens the existing medication and prevention facilities against an over increasing range of infections caused by a wide range of microbes. Specifically, treatment of Gram-negative bacterial infection is getting more problematic due to their resilience against β-lactam antibiotics: the most commonly prescribed antibiotics in clinical settings. Production of β-lactamases is the most prevalent mechanism utilized by various Gram-negative pathogens to become resistant to the β-lactam antibiotics e.g, penicillins, cephalosporins, carbapenems and monobactams. These enzymes mediate their function through hydrolyzing the core β-lactam ring present in all β-lactam antibiotics which causes opening of the ring and …
