Cefroxadine (CGP-9000), an orally active cephalosporin.
Cefroxadine (GCP-9000; CXD), 7 beta[D-2-amino-2-(1,4-cyclohexadienyl)-acetamido]-3-methoxy-ceph-3-em-carboxylic acid, is a new orally active cephalosporin derivative. The spectrum of antibacterial activity of CXD is identical with that of cephalexin (CEX), but CXD was twofold more effective than CEX against Escherichia coli and Klebsiella pneumoniae, CXD was as stable to penicillinase as CEX, b...
متن کاملCGP 9000: a new orally active, broad-spectrum cephalosporin.
CGP 9000, (7-[D-2-amino-2-(1,4-cyclohexadienyl)-acetamido]-3-methoxy-3-cephem-4-carboxylic acid), is a new broad-spectrum cephalosporin antibiotic. Its antibacterial activity in vitro (MIC) is similar, but its bactericidal efficacy superior to that of cephalexin and cephradine. Upon oral administration to mice infected with various bacteria, CGP 9000 is, in general, 2 to 7 times more effective ...

and 9b, were prepared as reported in the ref3). The other pivaloyloxymethyl esters, 9c, 9d and 9e, were prepared via another procedure, which is shown in Scheme 2. Other esters llp~ llw were prepared in the manner similar to that of 9e from the sodium salt of 5e and the corresponding halides. The latter halides were prepared from chloromethyl chlorosulfate (or chloromethyl iodide) and the corre-
متن کاملMechanism of action of the new orally active cephalosporin FK027.
The mechanism of action of a new orally active cephalosporin, FK027, was compared to that of cephalexin and cefaclor to elucidate its excellent antibacterial activity against Gram-negative bacteria. FK027 showed very high affinity for the penicillin-binding proteins (PBPs) 3, 1a and 1bs of Escherichia coli whereas cephalexin showed fairly high affinity for PBPs 1a, 4 and 3. The ability of FK027...
متن کاملComparative pharmacokinetics of cephalexin, cefaclor, cefadroxil, and CGP 9000.
In a randomized crossover study, the pharmacokinetics of three new cephalosporin antibiotics, cefaclor, cefadroxil, and CGP 9000, in comparison to cephalexin, were determined after oral administration, by capsules, of 1,000 mg on an empty stomach in 12 normal subjects. Serum concentrations were measured during a period of 8 h, and urine recovery was measured during 24 h. The significant paramet...
