In vivo MR signal enhancement post-treatment with (A & B) targeted fumagillin nanoparticles and (C & D) control (no drug). In the pre-treatment images, areas of Matrigel™ implantation have been marked with yellow arrows. In the post-treatment images, signal enhancement has been denoted with orange arrows. (E) Reduced Matrigel implant enhancement in rats treated with αvβ3-integrin-targeted nanoparticles with fumagillin-PD versus αvβ3-integrin-targeted nanoparticles with fumagillin, αvβ3-integrin-targeted nanoparticles without drug and nontargeted nanoparticles with fumagillin-PD.
NT: Nontargeted; PD: Prodrug.
