This moiety is the mainly responsible for the antibacterial properties of all these molecules, due to their ability to block the bacterial cell wall synthesis as a result of their covalent binding to penicillin-binding proteins (PBPs), which are essential enzymes involved in the terminal steps of the synthesis of peptidoglycan, the main component of the bacterial cell wall [ 9 ] .

The mechanism of resistance for any antibacterial agent varies, but is a result of either changes in uptake of drug into, or its removal from, the bacterial cell, or to changes in the bacterial cell target site of the drug from a gene mutation. (antiinfectivemeds.com)
