Pediatrics In Review, 1994
Introduction The first cephalosporin released for clinical use was cephalothin in 1964. Since that time, more than 20 cephalosporin antibiotics have been introduced. These are the most commonly prescribed antibiotics in the United States and account for the largest share of hospital expenditures. To determine which agent to use for an

Journal of Medicinal Chemistry, 1977
The acidic aqueous degradation of the 7alpha-aminophenylglycinamido-containing cephalosporin cephalexin (1a) has been examined. Two major degradation products have been isolated and characterized: 3-formyl-3,6-dihydro-6-phenyl-2.5(1H,4H)-pyrazinedione (5) and 3-hydroxy-4-methyl-2(5H)-thiophenone (6).

Continuous deacetylation of cephalosporins
Biotechnology and Bioengineering, 1980AbstractContinuous deacetylation of cephalosporin C, 7âaminocephalosporanic acid, and of 2âmethoxyethyl acetate in packed beds of an immobilized esterase is described by simple empirical equations relating conversion to space velocity and temperature.

Classification of Cephalosporins
Drugs, 1987Many cephalosporins are now in clinical use. They have a wide range of activity against different species of bacteria and also differ in their pharmacokinetic and metabolic characteristics. This article outlines a basis for comparison and classification of cephalosporins into 4 groups active mainly against: (1) Gram-positive bacteria; (2) Gram-negative

Expert Opinion on Emerging Drugs, 2007
Several cephalosporins are in clinical development as broad-spectrum agents with potent activity against multi-resistant staphylococci as well as the Gram-positive and Gram-negative bacteria normally susceptible to advanced generation cephalsoporins. These agents represent a novel activity for the class and challenge a dogma that beta-lactams do not ...
