説明Methicillin is a semisynthetic penicillin antibiotic that can inhibit bacterial cell wall synthesis. It can be used to study methicillin-resistance in S. aureus.

使用Targets primarily the cell wall of Gram-positive organisms especially Staphylococcus aureus. Methicillin is used to study bacterium susceptibility, and to inhibit cell-wall synthesis. PBP's are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Methicillin Sodium Salt is inactivated by gastric acid so it is given to cells by other means in which gastric acid is not present in vitro.
