Beta-lactams, in combination with beta-lactamase inhibitors, are reported to have activity against Mycobacterium tuberculosis bacteria growing in broth, as well as inside the human macrophage. We tested representative beta-lactams belonging to 3 different classes for activity against replicating M. tuberculosis in broth and nonreplicating M. tuberculosis(More)
Peptide hormones are known to bind to cell surface receptors as the first step in the generation of their effects on target tissues. However, it remains uncertain whether internalized hormone might also play a role in the production of longterm or trophic effects of peptide hormones. Because the peptide hormone angiotensin II appears to be internalized by(More)
The discovery of novel therapeutics for the treatment of tuberculosis involves routine testing in a mouse model over four weeks of daily dosing with test compounds. In this model, daily oral administration of rifampin (10 mg/kg) showed significantly lower plasma exposure on day 5 compared to day 1. The absence of PXR-mediated induction of mouse Cyp3a(More)
Robust and physiologically relevant infection models are required to investigate pharmacokinetic-pharmacodynamic (PK/PD) correlations for anti-tuberculosis agents at preclinical discovery. We have validated an inhalation-based rat infection model of tuberculosis harbouring mycobacteria in a replicating state, that is suitable for investigating(More)
Animal data suggest that angiotensin II may directly affect renal sodium retention independent of aldosterone (4,6). Additionally there is evidence to suggest that the hormone can stimulate protein synthesis in a variety of tissues and that indeed it may be a vasculotoxin (5,7). We describe here experiments designed to elucidate the role of angiotensin II(More)
