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.

There is growing interest in small peptidomimetic alpha(v)beta(3) integrin antagonists that are readily synthesized and characterized and can be easily handled using physiological conditions. Peptidomimetic 4-[2-(3,4,5,6-tetrahydropyrimidine-2-ylamino)ethyloxy]benzoyl-2-[N-(3-amino-neopenta-1-carbamyl)] -aminoethylsulfonyl-amino-beta-alanine (IAC) was successfully conjugated to 1-(1-carboxy-3-carbo-t-but-oxypropyl)-4,7-(carbo-tert-butoxymethyl)-1,4,7-triazacyclononane (NODA-GA(tBu)(3)) and 1-(1-carboxy-3-carbotertbutoxymethyl)-1,4,7,10-tetraazacyclododecane (DOTA-GA(tBu)(4)) and radiolabeled with In-111, Ga-67 and Pb-203. Results of a radioimmunoassay demonstrated binding to purified alpha(v)beta(3) integrin when 14 equiv of integrin were added to the reaction. Based on this promising result, investigations are moving forward to evaluate the NODA-GA-IAC and DOTA-GA-IAC conjugates for targeting tumor associated angiogenesis and alpha(v)beta(3) integrin positive tumors to define their PET and SPECT imaging qualities as well as their potential for delivery of therapeutic radionuclides.
