General description
Chemical structure: amino acid derivatives
Application
Alaphosphin is used as a selection agent for isolation of Salmonella and as a dipeptide mimetic antibacterial agent.
Biochem/physiol Actions
Alaphosphin is an antibacterial phosphonopeptide which mimics the terminal dipeptide moiety (D-Ala-D-Ala) of bacterial cell wall peptidoglycan . It metabolizes aminophosphonic acid which inhibits alanine racemase and uridine 5-diphosphate-N-acetylmuramoylalanine synthetase.

Dipeptide variants of alafosfalin (L-alanyl-L-1-aminoethylphosphonic acid) with substantial differences in potency and antibacterial spectrum in vitro and in vivo have been synthesized. Certain dipeptides with alternatives to the L-alanyl residue had broader antibacterial spectra; activity against Pseudomonas aeruginosa was included.
