Cephalosporin P1 is a naturally occurring antibiotic compound belonging to the cephalosporin class, which was first isolated from the fungus Cephalosporium acremonium (later reclassified as Acremonium chrysogenum). 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.
