Penicillins

Penicillins are a group of antibacterial agents derived from the Penicillium fungus and includes penicillin G, penicillin V, ampicillin and carbenicillin. Penicillins are β-lactams, which interfere with PBP (Penicillin Binding Protein) activity involved in the final phase of peptidoglycan synthesis. PBPs are enzymes that catalyze a pentaglycine cross-link between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine cross-link, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Many penicillins, such as ampicillin, amoxicillin and carbenicillin, are commonly used as selective agents in laboratory, bacterial screening protocols.

Description

Amoxicillin/Clavulanate combines an extended-spectrum β-lactam antibiotic with a β-lactamase inhibitor. Amoxicillin is an extended-spectrum ß-lactam antibiotic with a structure similar to that of ampicillin. It is effective against a variety of ß-lactamase negative bacteria including E. coli and various Streptococcus and Staphylococcus bacteria; however, when combined with clavulanic acid, ß-lactamase enzymes are irreversibly inactivated. Consequently, amoxicillin/clavulanate is effective against ß-lactamase-negative and ß-lactamase-positive bacteria.

Description

Ampicillin sodium is a member of the extended-spectrum β-lactam family and similar in structure to penicillin. It is used in the selection of antibiotic cell hybrids and has a high rate of action against many gram-negative bacterial strains. Ampicillin sodium targets non-ESBL (Extended Spectrum β-lactamase) bacteria including Staphylococcus and Streptococcus species and medically important enteric pathogens such as Shigella and Salmonella. It has been found to be effective against certain β-lactam sensitive VRE or vancomycin resistant Enterococcus species. Resistance to ampicillin is routinely utilized as a selectable marker to confirm successful cell transformation. Ampicillin Sodium is freely soluble in water.

Description

Carbenicillin is a member of the penicillin β-lactam antibiotics. However, unlike most β-lactams, carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species. It can be used in selection protocols and is often preferred over ampicillin due to its increased stability. This allows for less contamination of unwanted bacterial colonies. In addition, carbenicillin has been used to regulate bacterial growth in plants, yielding low regeneration frequencies. It can be used in genetic transformation applications to select for AmpR transformed cells.
