➤ Development of a new class of multifunctional reagents.
A strategy to access multifunctional nanomaterials, imaging probes, and sensors
with high levels of complexity was devised to overcome limitations associated
with current synthetic methods. "Multifunctional single-attachment-point"
(MSAP) reagents, featuring multiple functional groups and a single chemically
reactive group, were designed from a peptide scaffold. A series of MSAPs were
synthesized to permit multimodal detection (fluorochromes, metal chelates,
immunoreactive haptens), to modify nanomaterial properties (hydrophylic
polymers), or to confer a therapeutic pharmacological activity (drugs). When an
MSAP is reacted with a substrate (e.g. a nanoparticle, a protein, a small
molecule), a complex multifunctional probe is obtained in a single step. The
MSAP-based strategy was applied (i) to obtain multifunctional gold nanoparticles,
(ii) to prepare a bioactive multifunctional protein for multimodal imaging of
apoptosis, (iii) to study the localization in vivo of an integrin-targeting peptide,
and (iv) to construct an hypervalent therapeutic antibody.
➤ Synthesis and biological evaluation of a MR contrast agent of cell death.
A thiazole orange (TO) fluorochrome was modified and attached to a
paramagnetic Gd chelate to obtain GadoTO, a bimodal probe which maintained
the nucleic-acid binding property and the impermeability to healthy cells of TO.
Interaction of GadoTO with plasmid DNA was studied by relaxometry and
fluorescence. GadoTO was employed to image cell death by fluorescence (FACS,
microscopy) and MR (cellular T relaxation times).

➤ Design, synthesis and characterization of new targeting and vectorization
systems in cancer
Synthetic vectors targeting tumors and their associated neo-angiogenesis were
synthesized and evaluated for drug delivery and molecular imaging applications.
The vectors were devised to target the αVβ3 integrin receptor and to
simultaneously carry either a cytotoxic cargo or a contrast-enhancing agent. The
core of the vector was composed of a regioselectively addressable cyclic
decapeptide scaffold (RAFT) presenting two distinct domains allowing the spatial
separation of the targeting and delivery functions. The template was decorated
with multiple copies of a cyclo[-RGDfK-] peptide through chemoselective oxime
ligation. Conjugation of the vector with diverse detection molecules (biotin,
fluorescein, cyanin) allowed its biological evaluation in vitro and in vivo. In vitro
experiments revealed the tetrameric version to be the most potent in receptor-
specific binding and cell internalization. The lead structure RAFT(c[-RGDfK-])4
proved to induce αVβ3 integrin clustering and to be internalized through a receptor-mediated endocytosis. When administered systemically into immune deficient mice, (Cy5)RAFT(c[-RGDfK-])4 detected solid tumors as well as disseminated metastases. The vector was further modified with cytotoxic molecules, including an antibacterial amphiphilic peptide, a chemotherapeutic drug or a toxin protein, which were linked through a disulfide bridge allowing their release into the targeted cells. Tumor-suppressing potencies were evaluated in vivo. The vector was also coupled to optical and nuclear imaging agents for the detection of deep tumors and metastases in mice.
