RU44790

Class: Beta-lactam (monocarbam)

Spectrum of activity: Gram-positive
Details of activity: This exhibited no activity against Pseudomonas aeruginosa but demonstrated good activity against Klebsiella pneumoniae, Haemophilus influenzae, Morganella morganii and Proteus vulgaris.
Institute where first reported: Aventis (Sanofi Aventis, France)
Year first mentioned: 1986
Highest developmental phase: Preclinical
Development status: Inactive
Reason Dropped: No further documentation after 1992 (reference) which states pharmokinetics and trials needed- paper compares with aztreonam. It has very little activity against Gram positive bacteria but is stable against many derepressed chromosomal and plasmid encoded β-lactamases. Possibly not non-inferior to existing antibiotics or want of Gram positive efficient antibiotics at the time.
