1-Penicillin

Mechanism of action:
Beta-lactam antibiotics lyse bacteria by binding to cytoplasmatic membrane enzymes (penicillin-binding proteins).
This inhibits a step in peptidoglican synthesis that is crucial for cell wall formation.
All members of the family have a beta-lactam ring and a carboxyl group resulting in similarities in the pharmacokinetics and mechanism of action of the group members.

Antibiotics in a brief
1- Penicillin
Penicillins are beta-lactam antibiotics derived from 6-aminopenicillanic acid.
The natural penicillins include sodium and potassium salts of benzyl penicillins.
Semisynthetic penicillins possess properties that improve upon deficiencies of natural penicillins, including wider antimicrobial spectrum and decreased susceptibility to degradation by gastric acids and beta-lactamase enzymes
