Abstract: &bgr;-alethine is employed in the differentiation, phenotypic expression, and vitalization of cells, for both in vivo and in vitro applications. Particular applications include the use of &bgr;-alethine in the treatment of immune disorders and diseases, and in the promotion of cell cultures.

Abstract: Biomodulators, optionally linked to imaging-active moieties, can be administered to a host to enhance images thereof, e.g., NMR-, X-ray- or radio-images, preferably by increasing aberrant tissue signal intensity. Biomodulators can also condition tissue to enhance up-take of otherwise non-specific imaging agents. When linked to drugs, biomodulators can target the same to particular sites in the body.

Abstract: Biomodulators, which regulate cellular differentiation and proliferation, as well as methods of use thereof, e.g., for treating various conditions, e.g., cancer, senescence, immunological disorders and vascular disease; for stimulating normal tissue architecture after injury; for vaccination; for stimulating the production of biologically important molecules by cells or organs in culture; for maintaining organs or tissues outside of a body after removal from the body and prior to transplantation; and for producing of vascular grafts for transplantation; are provided.

Abstract: The invention provides cell modulators comprising certain biologically-active enantiomers of mevalonate and mevalonolactone derivatives. The compounds are broadly clinically useful, particularly in cancer management and treatment or immunological diseases or disorders.

Abstract: Biomodulators can be administered together with an agent such as a drug or an imaging agent (specific or non-specific) structurally modified to take advantage of perturbations of cell oligosaccharide displays caused by biomodulators, to enhance images of a host, e.g., NMR-, X-ray- or radioimages, preferably by increasing aberrant tissue signal intensity. Biomodulators condition tissue to enhance or otherwise modify up-take of the drug or structurally modified imaging agent.
