Hetacillin is a penicillin-like, beta-lactam-based antibiotic prodrug used to treat infections, usually from Gram-positive bacteria. It is sold under the brand names Hetacillin potassium®, Versapen® and Versapen-k®.
Mechanism of action
Hetacillin is a prodrug with no antibacterial activity, but it is metabolized into the antibiotic ampicillin. Hetacillin is prepared by reacting ampicillin with acetone because ampicillin is much less stable towards ring-opening reactions. Once converted to ampicillin, the ampicillin interferes with the final stage of cell wall synthesis by binding to penicillin-binding proteins, leading to autolysis of the bacteria by autolysin enzymes.
Chemistry
It is a beta-lactam structure, and its chemical name is (2S,5R,6R)-6-[(4R)-2,2-dimethyl-5-oxo-4-phenylimidazolidin-1-yl]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid. Its chemical formula is C19H23N3O4S (MW = 389.4686 g/mol). Hetacillin is susceptible to degradation in bacteria that produce beta-lactamase.
