Metabolite Identification
Common NamePenicilloic acid
DescriptionPenicilloic acid, also known as penicilloate, belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. Penicilloic acid is any of several acids which are obtained from the penicillins by the hydrolytic opening of the lactam ring (as by the action of a beta-lactamase). Penicilloic acid is a very strong basic compound (based on its pKa). The major antigenic determinant of penicillin hypersensitivity is its metabolite, penicilloic acid, which reacts with proteins and serves as a hapten to cause an immune reaction. To determine whether treatment with a β-lactam is safe when an allergy is noted, patient history regarding severity of previous reaction is essential. Among patients with mononucleosis who are treated with ampicillin, the incidence of maculopapular rash approaches 100 percent. Cross-allergic reactions occur among the β-lactam antibiotics. Approximately five percent of patients have some kind of reaction, ranging from maculopapular rash (the most common rash seen with ampicillin hypersensitivity) to angioedema (marked swelling of the lips, tongue, and periorbital area) and anaphylaxis. Hypersensitivity is the most important adverse effect of the penicillins.
