Abstract: The present invention relates to methods for modulating the growth of tumor and pathogen cells and the resistance of cells to foreign compounds, i.e. drugs, antibiotics, etc. by altering the ATP gradient across biological membranes. The altering of the ATP gradient across biological membranes is achieved through the manipulation of ecto-phosphatase activity and ABC transporter molecule activity which may also be useful to confer herbicide resistance to plants, confer antibiotic resistance to bacteria, confer drug resistance to yeast cells, or to reduce resistance in cells to facilitate chemotherapeutic treatments, and to reduce resistance in bacteria and yeast. The present invention is also directed to the methods for identifying ecto-phosphatase inhibitors and uses thereof.

Abstract: The present invention relates to the modulation of pesticidal and herbicidal activity by treatment of a membrane transport system in a cell. This entails modifying the extra-cellular phosphatases found in the membranes of these cells. By modifying the ATP gradient across the biological membrane of a target plant, bacteria, insect or mammalian cell via inhibiting one or more extra-cellular phosphatases, it is possible to alter the sensitivity to a pesticide or herbicide.

In preferred embodiments, the chemical moieties of the invention act as adjuvants to enhance pesticidal activity.

Abstract: The present invention relates to methods for decreasing the resistance of microbial strains to antiinfectives such an antibiotics and antifungals by altering the ATP gradient across biological membranes. The altering of the ATP gradient across biological membranes is achieved through the inhibition of ecto-phosphatase activity and/or ABC transporter molecule activity which may be useful to reduce resistance in bacteria and yeast to aid in the treatment of certain infections and disease and to lower the concentration of antiinfectives necessary to inhibit the growth of microbial strains.
