    摘要: A method for increasing the target-specific toxicity of a drug is effected by pretargeting an enzyme to a mammalian target site, and then administering a cytotoxic drug known to act at the target site, or a prodrug form thereof which is converted to the drug in situ, which drug is also detoxified to form an intermediate of lower toxicity using said mammal's ordinary metabolic processes, whereby the detoxified intermediate is reconverted to its more toxic form by the pretargeted enzyme and thus has enhanced cytotoxicity at the target site. Further enhancement can be achieved by pretargeting an enzyme which converts the prodrug to the cytotoxic drug at the target site. Kits for use with the method also are provided. The method and kits permit lower doses of cytotoxic agents, maximize target site activity and minimize systemic side effects.

    摘要: Composite probes for super resolution optical techniques using super resolution via transiently activated quenchers (STAQ) include a donor moiety and an acceptor moiety joined by a linker, wherein the acceptor moiety, when excited by incident radiation, is excited to a state which, for example, absorbs in the donor emission region, such that the acceptor moiety in its excited state quenches at least a portion of the donor moiety emission. Other transiently activated quenching mechanisms and moieties could accomplish the same task by reducing donor population. Also disclosed are methods for irradiating a selected region of a target material including the composite probe, wherein the composite probe enables improved resolution by point spread function modification and/or nanoscale chemical reactions.

    摘要: A method of producing a diagnostic or therapeutic conjugate of a protein, polypeptide or peptide containing at least one disulfide bond which is necessary to maintain its biological activity, and bearing at least one thiol-containing moiety linked thereto through a hydrazone or hydrazine linkage, is effected by contacting said protein, polypeptide or peptide with a thiol-reactive diagnostic or therapeutic agent, either preformed or generated in situ, to form a stable diagnostic or therapeutic conjugate of the protein, polypeptide or peptide without substantial cleavage of the disulfide bond. Diagnostic and therapeutic conjugates produced using the foregoing method, as well as kits for carrying out the method are provided.
