The invention describes a vitamin receptor binding drug delivery conjugate, and preparations therefor. The drug delivery conjugate consists of a vitamin receptor binding moiety, a bivalent linker (L), and a drug. The vitamin receptor binding moiety includes vitamins, and vitamin receptor binding analogs and derivatives thereof, and the drug includes analogs and derivatives thereof. The vitamin receptor binding moiety is covalently linked to the bivalent linker, and the drug, or the analog or the derivative thereof, is covalently linked to the bivalent linker, wherein the bivalent linker (L) includes components such as spacer linkers, releasable linkers, and heteroatom linkers, and combinations thereof. Methods and pharmaceutical compositions for eliminating pathogenic cell populations using the drug delivery conjugate are also described.

This invention relates to vitamin-mitomycin conjugates, to a method of using the conjugates to selectively eliminate a population of pathogenic cells in a host animal harboring the pathogenic cells, and to a method of preparation of the conjugates. The conjugate is of the general formulaB-L-Xwherein the group B is a vitamin, or an analog or a derivative thereof, that binds to a surface accessible vitamin receptor that is uniquely expressed, overexpressed, or preferentially expressed by a population of pathogenic cells, wherein the group L comprises a cleavable linker, and wherein the group X comprises a mitomycin compound, or an analog or a derivative thereof. An additional therapeutic agent, such as a chemotherapeutic agent, can be administered in combination with the conjugate.

The invention relates to compounds and methods for targeting radionuclide-based imaging agents to cells having receptors for a vitamin, or vitamin receptor binding derivative or analog thereof, by using such a vitamin as the targeting ligand for the imaging agent. The invention provides a compound of the formula for use in such methods. In the compound, V is a vitamin that is a substrate for receptor-mediated transmembrane transport in vivo, or a vitamin receptor binding derivative or analog thereof, L is a divalent linker, R is a side chain of an amino acid of the formula H2NCHRCOOH, M is a cation of a radionuclide, n is 1 or 0, K is 1 or 0, and the compound can be in a pharmaceutically acceptable carrier therefor. The vitamin-based compounds can be used to target radionuclides to cells, such as a variety of tumor cell types, for use in diagnostic imaging of the targeted cells.
