We investigated the prophylactic effect of Ubenimex on mice with ascending pyelonephritis induced by Pseudomonas aeruginosa (G-group). This experimental model was established by a two course administration of cyclophosphamide, so that it kept the mice in a neutropenic status (around 2000 white blood cells/mm3) from the time of infection to the time of sacrifice. The cyclophosphamide-treated group increased their susceptibility more than the control group. In the cyclophosphamide-treated group, the prophylactic administration of Ubenimex (100 micrograms/day/mouse) did not produce significant decreases of infection-induced mortality rate, but yielded a lower incidence of infection than of saline alone. Administration of Ubenimex was not able to increase the number of neutrophils during the experiment. An investigation of the bactericidal capacity of peritoneal exudating neutrophils revealed that Ubenimex prophylactic administration accelerated its capacity, although cyclophosphamide alone did not. These results suggest that Ubenimex has a prophylactic effect on bacterial infection in neutropenic mice, and that this effect, in part, depends upon the acceleration of bactericidal capacity of neutrophils produced by Ubenimex.

A two-stage protocol designed to evaluate putative immunomodulators for use in infectious disease has been proposed. In this report the effect of bestatin on a series of clinically relevant, and sub-lethal infections is described. Pyelonephritis, peritonitis and bacteremia were induced with Escherichia coli, while Klebsiella pneumoniae was used to produce a lung infection. Bestatin had no effect on the course of these infections. In a further experiment we assessed the effect of combined bestatin/antibiotic therapy on the course of renal infection. Again no effect was observed. These findings are consistent with the known immunomodulatory properties of bestatin. This methodology will be used to evaluate selected agents for their potential in infectious disease and should lead to useful clinical protocols.
