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.
本发明涉及一种新的方法和组合物,可用于预防和改善消瘦症,即与癌症和其他慢性疾病相关的营养不良和身体消耗的临床综合征。更具体地说,本发明涉及芳香基胍基脲(更准确地称为胍基脲)组合物及其用于抑制巨噬细胞对精氨酸的摄取和/或将其转化为尿素的作用。这些组合物和方法也可用于预防细胞生成一氧化氮(NO),从而预防需要同样反应的人体内的NO介导的炎症和其他反应。在另一种实施方式中,这些化合物可用于抑制精氨酸依赖性肿瘤和感染中的精氨酸摄取。
