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.

Alafosfalin, an antibacterial phosphonodipeptide requiring peptide transport for activity, was tested for activity against clinical strains of anaerobic bacteria in peptide-free Roche Sensitivity Test Medium no. 5 agar. It was active against Bacteroides spp., Fusobacterium nucleatum, and Clostridium perfringens but

Antimicrobial agents and chemotherapy, 18(6), 897-905 (1980-12-01)
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.
