6-Aminopenicillanic acid (6-APA) is the central component of penicillin β-lactam antibiotics which are generated by Penicillium. 6-APA forms from penicillin G after being catalyzed by penicillin acylases. This compound can be used to create semi-synthetic antibiotics that are effective against non-penicillinase forming bacterium, such as Streptococcus and some Staphylococcus.

6-APA is used as precursor for antibiotic compounds ampicillin and amoxicillin. Antibiotic synthesis of 6-APA can be augmented with a supersaturated solution of nucleophiles. Other methods for enhancing effectiveness involves diminishing ionic strength in a reaction mixture along with the addition of 2-butanol. Implementing a pH gradient starting at pH 7 and reducing the pH to 6.5 near reaction completion can greatly increase reaction output.

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. It is also effective against a variety of other gram-negative and gram-positive bacteria. Amoxicillin sodium salt is freely soluble in aqueous solution.

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.

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.

Resistance to ampicillin is routinely utilized as a selectable marker to confirm successful cell transformation. Ampicillin trihydrate is slightly soluble in water and freely soluble in 1N HCl.

Ampicillin/sulbactam (2:1) is a broad-spectrum combination of a β-lactam antibiotic with a β-lactamase inhibitor. It is used for in vitro susceptibility tests in microbiology, pharmacokinetics and pharmacodynamics studies.

Ampicillin binds to the active site of penicillin binding proteins (PBP), preventing peptidoglycan cross-link formation of the bacterial cell wall. Inhibition of PBPs weakens the bacterial cell wall and leads to cell lysis. Sulbactam irreversibly inhibits β-lactamase enzymes generated by bacteria, preserving ampicillin activity and enhancing potency.

Azlocillin is an extended-spectrum β-lactam antibiotic derived from ampicillin. It is useful against P. aeruginosa, E. coli, H. influenzae, and a variety of other gram-negative species. It has also been used to develop antibiotic counting techniques. Azlocillin sodium is freely soluble in aqueous solution.

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.
