How It Works

Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.

Mechanism Steps

1Cefalexin binds to penicillin-binding proteins (PBPs) on the bacterial cell wall.
2Inhibition of transpeptidase enzymes prevents cross-linking of peptidoglycan chains.
3Autolytic enzymes are activated, leading to cell wall weakening and lysis.
