Abstract:

The present invention provides functionalized chelants and a method of treating cancerous cells with alpha particles comprising the step of administering a pharmacologically effective dose of an Ac conjugate comprising a functionalized chelant R is independently CHQCO X; Q is independently hydrogen; C1-C4 alkyl or (C1-C2 alkyl) phenyl; X is independently hydrogen; benzyl or C1-C4 alkyl; Z1 is (CH ) Y where n is 1-10 and Y is an electrophilic or nucleophilic moiety and Z2 is R; or, alternatively, Z1 is hydrogen and Z2 is a peptide linker composed of 1-10 amino acids; said Y or said peptide linker covalently attached to an antibody or fragment thereof, or other biologic molecule; or a pharmaceutically acceptable salt thereof, complexed with Ac. These biologic molecule binds to cancerous cells and Ac or its daughters emit alpha particles into said cancerous cells effecting treatment.

US Classification:

424 91, 424 93, 424 932, 424 9322, 424 934

Abstract:

The present invention provides soluble single wall nanotube constructs functionalized with a plurality of a targeting moiety and a plurality of one or more payload molecules attached thereto. The targeting moiety and the payload molecules may be attached to the soluble single wall carbon nanotube via a DNA or other oligomer platform attached to the single wall carbon nanotube. These soluble single wall carbon nanotube constructs may comprise a radionuclide or contrast agent and as such are effective as diagnostic and therapeutic agents. Methods provided herein are to diagnosing or locating a cancer, treating a cancer, eliciting an immune response against a cancer or delivering an anticancer drug in situ via an enzymatic nanofactory using the soluble single wall carbon nanotube constructs.

US Classification:

424/001490

Abstract:

Provided herein are methods of reducing nephrotoxicityfrom at least one alpha particle-emitting daughter of actinium-225 during radioimmunotherapeutic treatment for a pathophysiological condition, methods of improving radioimmunotherapeutic treatment of cancer and methods of increasing the therapeuticindex of an actinium-225 radioimmunoconjugate during treatment of a pathophysiological condition. Adjuvants effective for preventing accumulation of Ac daughters within the kidneys are administered during treatment with an actinium-225 radioimmunoconjugate to reduce nephrotoxicity. Examples of adjuvants are chelators, diuretics and/or competitive metal blockers.
