摘要:
Vitamin B.sub.12 receptor modulating agents capable of modulating cell surface receptors by affecting the cell surface receptor trafficking pathway are disclosed. The vitamin B.sub.12 receptor modulating agents are comprised of a covalently bound rerouting moiety and targeting moiety linked by a water-solublizing linker.
摘要:
A biotinylated cobalamin, formed from a vitamin B.sub.12 molecule coupled to a biotin molecule, is disclosed. In a preferred embodiment, the vitamin B.sub.12 molecule is cyanocobalamin. The biotin molecule can also be coupled to a rerouting moiety, optionally through a biotin binding protein such as avidin or streptavidin. The biotinylated cobalamin binds to a cell surface receptor, is invaginated, and once internalized affects the receptor trafficking pathway.

摘要:
The present invention involves a method of imaging tissue sites of inflammation which takes advantage of the up-regulation of surface antigenic markers on leukocytes upon activation thereof. A recognition agent selected from the group of chemotactic peptides, eosinophilic peptides and agents which are capable of selective interaction with a chemotactic receptor associated with activated leukocytes is radiolabeled. The radiolabeled recognition agent is infused into a patient and the patient's tissue sites are thereafter imaged in order to detect, evaluate or monitor tissue damage mediated by inflammation.
摘要:
The present invention involves methods of enhancing the amount of target site localization of lymphoid cells. Methods of the present invention take advantage of the up-regulation of surface antigenic markers on lymphoid cells upon activation thereof. Imaging and therapeutic applications of such enhancement are described.
摘要:
Targeting substance-diagnostic/therapeutic agent conjugates joined by stabilized Schiff base or hydrazone linkages are disclosed. In addition, slow release carrier-drug pharmaceuticals are described. The diagnostic and therapeutic conjugates and pharmaceuticals of the present invention provide certain advantages relating to in vivo administration, including controlled release of the active agent at a target site.
摘要:
Covalently-linked complexes (CLCs) for targeting a defined population of cells, comprising a targeting protein; a cytotoxic agent; and an enhancing moiety, wherein the enhancing moiety is capable of promoting CLC-target cell interaction are disclosed. Methods for using the claimed CLCs to obtain enhanced in vivo cytotoxicity and enhanced in vivo imaging are also described.
摘要:
Methods are disclosed for increasing the solubility of antibodies and their radioisotope, toxin, or drug immunoconjugates and for reducing the non-specific uptake of antibody, either conjugated or unconjugated, into the RES organs such as via Fc receptor-mediated mechanisms. The methods involve incubation of the reactive component with amphipathic molecules, such as an anionic detergent, to achieve the desired result. A preferred anionic detergent in this regard is sodium dodecylsulfate.
