Pyrazinone conjugates as potential cephalosporin allergens
摘要:
Cephalosporins with an alpha -amino group on the 7-beta -acyl substituent have been shown to undergo aminolysis with subsequent formation of a fluorescent pyrazinone degradation product. An analogous reaction seems to take place upon in vitro conjugation of such cephalosporins to albumins and polylysine. A corresponding pyrazinone-polylysine conjugate was able to bind IgE antibodies in sera from patients with suspected allergy to p-lactams. These findings may have applications in the diagnosis of allergy against aminocephalosporins. (C) 2001 Elsevier Science Ltd. All rights reserved.
