Described herein is a non-invasive quantitative positron emission tomography (PET) nanoreporter technology that allows personalized therapeutic outcome prediction. In a breast cancer mouse model, it was demonstrated that co-injecting Doxil and a Zirconium-89 nanoreporter (89Zr-NRep) enabled highly precise doxorubicin (DOX) quantification. Imaging 89Zr-NRep via PET revealed remarkable Doxil accumulation heterogeneity independent of tumor size.

A label for an antibody or protein is described that is both site-selective and unusually stable in vivo. The label has a general formula given by Formula (I) wherein R1 is a metal chelator, a fluorophore or a click-chemistry synthon.
Provided herein are dendrimer-targeting agent conjugates comprising a dendrimer, the dendrimer comprising a core unit and lysine or lysine analogue building units, a HER2 targeting agent which is a peptidic moiety having a molecular weight of up to about 80 kDa and comprising an antigen-binding site, which is covalently linked by a spacer group, and a therapeutic agent which is covalently linked to a surface building unit of the dendrimer. Also provided herein are compositions comprising the conjugates, and therapeutic methods using the conjugates, particularly for treating cancer.

Novel synthetic methods for producing an array of chelates for use in “click”-radiolabeling of peptides are described, and their reactivity with regards to subsequent conjugation and radiolabeling is discussed.
Provided herein is dendrimer-targeting agent conjugate comprising: (a) a dendrimer comprising i) a core unit (C); and ii) building units (BU), wherein the dendrimer has from two to six generations of building units; and wherein the core unit is covalently attached to at least two building units; and the dendrimer further comprising: b) a targeting agent which is covalently linked to the dendrimer by a spacer group; c) one or more first terminal groups attached to an outermost building unit of the dendrimer, wherein the first terminal group comprises a complexation group for complexing a radionuclide; and d) one or more second terminal groups attached to an outermost building unit of the dendrimer, wherein the second terminal group comprises a pharmacokinetic-modifying moiety, or a salt thereof. Also provided are compositions comprising the dendrimer-targeting agent conjugates, and methods of using the dendrimer-targeting agent conjugates and compositions comprising them in therapeutic and imaging applications.
