  • Patent number: 5750573
    Abstract: This invention concerns new methods and compositions that are useful in preventing and ameliorating cachexia, the clinical syndrome of poor nutritional status and bodily wasting associated with cancer and other chronic diseases. More particularly, the invention relates to aromatic guanylhydrazone (more properly termed amidinohydrazone) compositions and their use to inhibit the uptake of arginine by macrophages and/or its conversion to urea. These compositions and methods are also useful in preventing the generation of nitric oxide (NO) by cells, and so to prevent NO-mediated inflammation and other responses in persons in need of same. In another embodiment, the compounds can be used to inhibit arginine uptake in arginine-dependent tumors and infections.
