Question 4 A series of 6-arylmethylidene penicillin-based sulfone inhibitors (1) were developed as a combination treatment to restore the efficacy of a series of B-lactam antibiotics in bacterial species that carry carbapenem- hydrolyzing B-lactamases. The proposed mechanism of inhibition involves the formation of the enzyme-molecule adduct 2. Please provide an arrow-pushing mechanism using strictly serine as a nucleophile.
