Amoxicillin covers a wide variety of gram-positive bacteria, with some added gram-negative coverage compared to penicillin. WebDesigning Penicillins That Resist Being Inactivated by β-lactamases. Many bacterial species can synthesise their own β-lactamases which will target and disable penicillins. Penicillins themselves can be modified to provide some protection against these enzymes. For example, in methicillin, bulky substituted benzene (at the variable R site of ...
