Pentizidone is a prodrug which is hydrolyzed spontaneously and converted to D-cycloserine. Merck selected pentizidone as a companion product for D-fluoroalanine with the anticipation that it would be better tolerated than cycloserine itself. The expectation was that D-fluoroalanine and pentizidone would be synergistic in killing bacteria. The combination of the two enzyme inhibitors proved to have potent antibiotic activity in animal studies and abolished the self-reversal phenomenon. D-cycloserine acts on D-alanyl-D-alanine synthetase.
