Cephalosporin P1

Cephalosporin P1 is a naturally occurring antibiotic compound belonging to the cephalosporin class, which was first isolated from the fungus Cephalosporium acremonium. It is one of the early cephalosporins discovered, alongside cephalosporin C and other related metabolites.
Fusidane-type antibiotics are a class of triterpenoid antibiotics that include helvolic acid, fusidic acid, and cephalosporin P₁. Among these, fusidic acid is notable for its clinical use in treating bacterial infections.

Uses

Unlike later-generation cephalosporins used clinically, cephalosporin P₁ has limited therapeutic use due to its weaker antibacterial activity.
Cephalosporin P₁ demonstrated strong effectiveness against methicillin-sensitive Staphylococcus aureus, methicillin-resistant S. aureus, and vancomycin-intermediate S. aureus strains.
