Definitions
- the present invention relates generally to compounds, compositions and methods for the diagnosis and therapy of diseases in warm-blooded animals (e.g., in humans) involving infections with and colonization by Pseudomonas bacteria, including Pseudomonas aeruginosa in the lungs of patients with cystic fibrosis.
- the 0 invention relates more particularly to the use of one or more compounds selective for binding Pseudomonas bacteria. These compounds are useful for diagnosis and/or therapeutic intervention of the colonization of Pseudomonas bacteria, or may be linked to an agent(s) to target and effectively arrest or kill Pseudomonas bacteria.
- Pseudomonas infections occur in a variety of medical conditions and can be life threatening.
- Pseudomonas is an opportunistic bacterium. Examples of individuals at risk include cystic fibrosis patients and burn patients. Cystic fibrosis is described below as a representative example of a medical condition which can involve infection with Pseudomonas bacteria.
- Cystic Fibrosis CF is the most common lethal genetic disease among the Caucasian population. CF is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR), which acts as a chloride channel.
- CFTR cystic fibrosis transmembrane conductance regulator
- the genetic mutations of CFTR which alter ion movements also affect the N- glycosylation of CFTR as well as other cell surface molecules. All of the exocrine 5 glands of the patients are affected; however, the lungs are the primary site of morbidity and mortality. The general change in glycosylation results in an increase in Lewis fucosylation and a decrease in sialylation.
- the salivary and respiratory musins from CF patients also contain higher levels of Lewis type oligosaccharides including sialylated and sulfated Lewis x/a structures.
- this invention provides compounds, compositions and methods for utilizing lectins expressed on Pseudomonas bacteria for the detection of Pseudomonas bacteria and the diagnosis and therapy of disease involving Pseudomonas bacteria, including human disease.
- glycomimetics of the Lewis structures that have high affinity binding to the lectins on P. aeruginosa will have a beneficial therapeutic effect on CF patients.
- these glycomimetics may be conjugated, for example, with strong antibiotics to increase the efficacy and lower the dose, thereby avoiding well known deleterious side effects of these potent antibiotics. Given that these binding sites are crucial for the colonization and pathogenicity of the bacterium, mutations in this target to become resistant to this conjugate therapy should result in non-pathogenic forms of the bacteria.
- One embodiment of the present invention provides a method of inhibiting Pseudomonas bacteria in a warm-blooded animal comprising administering to the animal in an amount effective to inhibit the bacteria a compound comprising a compound according to Figure 1 or Figure 2.
- the present invention provides a conjugate comprising a therapeutic agent linked to a compound according to Figure 1 or Figure 2.
