Superparamagnetic fluorescent nanoparticles targeting αvβ3 integrins were elaborated using two methodologies: carbodiimide coupling and click chemistries (CuACC and thiol-yne). The nanoparticles are first functionalized with hydroxymethylenebisphonates (HMBP) bearing carboxylic acid or alkyne functions. Then, a large number of these reactives functions were(More)
Magnetic Resonance Imaging (MRI) using contrast agents is a very powerful technique for diagnosis in clinical medicine and biomedical research. The synthesis of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles targeting αvβ3 integrins and acting as new MRI contrast agents seems to be a promising way for cancer diagnosis. Indeed, it is well(More)
In silico optimisation, synthesis and binding evaluation of αvβ3 integrin's affinity for precursors of a new RGD peptidomimetics family are presented. The 2-pyrrolidinone building block was obtained by condensation of l-lysine with dimethoxydihydrofuran followed by reduction. The ring was functionalized with a carboxylic acid and a guanidinium appendage. On(More)
AIM Tunable size ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles from 3 to 9 nm coated with polyethylene glycol phosphonate moieties have been designed for neovascularization MRI. MATERIALS & METHODS USPIO were synthesized using a nonaqueous sol-gel method. An ischemia-reperfusion rat model has been chosen for neo-angiogenesis and scanned on(More)
