Abstract: The present invention provides novel in vitro assays for determining the nephrotoxicity of a compound. These assays correlate well with in vivo nephrotoxicity and also provide high-throughput methods to screen multiple compounds for in vivo nephrotoxicity. In addition, the methods of the present invention may be adapted to screen for nephroprotectant compounds, including those that protect cells and animals from the nephrotoxic effects of aminoglycoside antibiotics.

Abstract: The present invention provides methods and compositions for said inhibition of drug resistance. In one embodiment, said invention provides methods and compositions for said inhibition of antibiotic resistance. The invention generally involves said administration of achaogens, agents that inhibit said mutational process, to inhibit said evolution of drug resistance. Also, described herein are compositions that are suitable for use as achaogens.

Abstract: The present invention is directed to analogs of aminoglycoside compounds as well as their preparation and use as prophylactic or therapeutics against microbial infection.

Abstract: Business methods for the commercialization of antimicrobial and cytotoxic compounds, including antibiotics and chemotherapeutic agents, are disclosed. According to one embodiment of the invention, drugs that are found to be effective but unsafe at therapeutic dosages are rescued by way of the use of an inhibitor of DNA repair, recombination, or replication, which sensitized microorganisms and cells, thereby permitting their use at a lower and safe dosage. In another embodiment, drugs that are found to be effective but cost prohibitive are rescued by way of the use of an inhibitor of DNA repair, recombination, or replication, thereby permitting their use at lower dosages and costs. A biopharmaceutical company may then, commercialize or charge royalties on such drugs.

Abstract: The present invention provides compositions useful in treating drug-resistant microorganisms and cells, as well as related methods of identifying and using such compositions. In addition, the present invention includes compositions useful in enhancing the sensitivity of both drug-resistant and drug-sensitive microorganisms and cells to microbicidal and cytotoxic agents, including antibiotics and chemotherapeutic drugs. Methods of identifying these compositions, as well as methods of using these agents in treating both drug-resistant and drug-sensitive diseases and conditions are further provided.
