General description

Chemical structure: ß-lactam

Application

Phenoxymethylpenicillinic acid, also known as Penicillin V, is a narrow spectrum antibiotic used to treat mild to moderate infections caused by susceptible bacteria. It is a natural penicillin antibiotic that is administered orally. Penicillin V is a penicillin β-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. It is commonly used in cell culture in combination with streptomcyin and other antibiotics. It is used to study penicillin-binding protein 2, molecular cloning of the Bacillus sphaericus penicillin V amidase gene, and gastrointestinal persistence and bile tolerance of Listeria monocytogenes.

Biochem/physiol Actions

Phenoxymethylpenicillinic acid binds to specific penicillin-binding proteins (PBPs) and inhibits the synthesis of bacterial cell walls by preventing cell wall peptidoglycan chain cross-linking. This causes cell lysis, which is mediated by autolytic enzymes such as autolysins. Phenoxymethylpenicillnic acid may interfere with autolysin inhibitors.

The Bacillus sphaericus gene coding for penicillin V amidase, which catalyzes the hydrolysis of penicillin V to yield 6-aminopenicillanic acid and phenoxyacetic acid, has been isolated by molecular cloning in Escherichia coli. The gene is contained within a 2.2-kilobase HindIII-PstI

In Neisseria gonorrhoeae, the mosaic structure of penicillin-binding protein 2 (PBP 2), composed of fragments of PBP 2 from Neisseria cinerea and Neisseria perflava, was significantly associated with decreased susceptibility to cephalosporins, particularly oral cephalosporins. The aim of this study

Two well-known antibiotic heterocycles, the 'quinolone' nalidixic acid and the β-lactam penicillin V, active at different levels of the bacterial growth process, have been attached via an ether-ester junction to the p-tert-butylcalix[4]arene lower rim, in alternate position. The resulting hydrophobic
