Eremomycin

Synonym(s): A82846A

Class: Glycopeptide

Spectrum of activity:	Gram-negative
Details of activity:	Cell Wall Inhibitor; Active against Clostridium difficile. Additionally in mice models of Staphyloccal septicaemia this was more effective than vancomycin.
Institute where first reported:	Russian Academy of Medical Sciences
Year first mentioned:	1988
Highest developmental phase:	Phase 2
Development status:	Inactive
Reason Dropped:	In a trial where animals were adminstered the body surface area extratrapolated doasege equivalent to the human dosage, there were some undesired side effects such as a significant increase in blood serum urea and also prolonged use at a high dosage revealed damaging side effects to kidneys and epithelium of the gastrointestinal tract which were reversible (1) But a derivative of chloroeremomycin was eventually developed as oritavancin (LS)
