diamine-containing effluxpumpinhibitors with respect to in vitro potentiation activity, in vivo stability and acute toxicity, we addressed the question of how to control the pharmacokinetic properties of the series. Upon intravenous administration in the rat, tissue levels of MC-04,124 (the lead compound) were high and prolonged compared to those in the serum. The lipophilicity and basicity of analogues of this

Disclosed herein are Efflux Pump Inhibitor (EPI) compounds that can be co-administered with antimicrobial agents for the treatment of infections caused by drug resistant pathogens. The EPI compounds are soft drugs which exhibit a reduced propensity for tissue accumulation. It is demonstrated that the EPIs can be used to increase the potency, decrease bacterial resistance and development of bacterial resistance, and increase killing effectivness of tigecycline. Also disclosed are methods of treatment and pharmaceutical compositions for co-administering tigecylcine with an EPI.

Synthetic optimization of a biologically labile class of dipeptides that function as efflux pump inhibitors to potentiate the antibacterial agent levofloxacin in Pseudomonas aeruginosa has led to the discovery of a related series of compounds that are completely stable in a variety of biological matrices. Other than the stability profile, the in vitro profile of the new series is essentially identical to that observed with the original one. A prototypical compound from the new series demonstrates potentiation in an in vivo model of infection. (C) 2001 Elsevier Science Ltd. All rights reserved.
