General description
Chemical structure: β-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

Listeria monocytogenes must resist the deleterious actions of bile in order to infect and subsequently colonize the human gastrointestinal tract. The molecular mechanisms used by the bacterium to resist bile and the influence of bile on pathogenesis are as yet

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
