Tebipenem pivoxil
Tebipenem Pivoxil is an orally available pivaloyloxymethyl ester prodrug of tebipenem, a broad-spectrum 1-beta-methylcarbapenem antibiotic with a 1-(1,3-thiazolin-2-yl) azetidin-3-ylthio group at the C-2 position. After oral administration of tebipenem pivoxil, the ester bond is cleaved, releasing active tebipenem.
