How Do Extended-Spectrum Penicillins Work?

Extended-spectrum penicillins are a group of semi-synthetic penicillin antibiotics that, because of their chemical structure, have a wider spectrum of activity than natural penicillins, penicillinase-resistant penicillins, and aminopenicillins. They are strongly effective against gram-negative bacterial infections.

Extended-spectrum penicillins work by inhibiting bacterial cell wall synthesis (cell walls are necessary to protect the bacteria from their environment and keep the contents of the cell together) by attacking the peptidoglycans (a mesh-like structure that increases the strength of the cell wall) leading to the bursting of the bacteria and eventually its death.
