Request a sales quoteSmall Molecular Immunomodifiers of Microbial Origin: Fundamental and Clinical Studies of Bestatin focuses on the results of experimental and clinical studies suggesting that bestatin and small molecular weight immunity-enhancing agents can contribute to the treatment of cancer and resistant infections. The selection first offers information on the screening, discoveries, and genetics of microbial secondary metabolites and activity of bestatin. Topics include the effect of bestatin on colony formation of murine bone marrow progenitor cells in vitro; antitumor effect of bestatin on murine transplantable tumors; and structures and properties of bestatin, amastatin, forphenicine, and esterastin. The text then examines the effects of bestatin on DNA and RNA metabolism in T-cells and levamisole and bestatin in immunodefficient aged mice. The text examines the influence of bestatin on the lymphoid system in humans, natural killer activity, and bone marrow. The preliminary phase I study of bestatin in lung cancer cases and malignant skin tumors are discussed. Topics include dosage schedule, clinical findings, and changes in immunological parameters. The selection is a vital reference for readers interested in the applications of bestatin in the treatment of cancer and resistant infections.
