Cefetecol (GR69153)

Class: Beta-lactam (cephalosporin)

Spectrum of activity:	Gram-positive  &  Gram-negative
Details of activity:	Use against Enteric infections
Institute where first reported:	GSK, USA
Year first mentioned:	1989
Highest developmental phase:	Phase 1
Development status:	Inactive
Reason Dropped:	Catechol-containing compounds: MIC50s « 0.008-0.39 μg/mL against P. aeruginosa are superior to that of ceftazidime. These catecholic ,B-lactams were expected to show superior therapeutic responses against pseudomonal infections in humans, but they were discontinued due to side effects or unfavourable pharmokinetics in phase I/ II studies (2)
