The present invention provides methods for guiding preservation of human neurons or human nerves during surgery by administering a fluorescently-labeled peptide that specifically binds to the human neurons or human nerves. The invention further provides human neuron or nerve targeting molecules comprising fluorescently-labeled peptides that specifically bind to human neurons or human nerves and compositions thereof.

Optimized peptides for targeting human nerves and their use in image guided surgery, diagnostic and therapeutic delivery

This disclosure provides compositions of metal-binding fluorinated compounds and associated methods for producing cellular labels for tracking cells by magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), and related methods.

Compositions and methods for imaging cell populations

Optimized peptides for targeting human nerves and their use in image guided surgery, diagnostics and therapeutic

Disclosed herein, in certain embodiments, is a selective transport molecule with increased in vivo circulation. In some embodiments, a selective transport molecule disclosed herein has the formula (A-X-B-C)-M, wherein C is a cargo moiety; A is a peptide with a sequence comprising 5 to 9 consecutive acidic amino acids, wherein the amino acids are selected from: aspartates and glutamates; B is a peptide with a sequence comprising 5 to 20 consecutive basic amino acids; X is a linker; and M is a macromolecular carrier.

Peptides whose uptake in cells is controllable

Compounds and methods for determining transmembrane potential, monitoring changes in transmembrane potential, and/or drug screening are provided. In one aspect, compounds of the invention have a structure according to the formula: E-M-A, wherein A is a fluorophore, selected from xanthenes, coumarins, cyanines, bimanes, and difuloroboradizaindacenes, charged at physiological pH; M is a molecular wire; and E is a hydrophobic moiety, wherein A and E are capable of being involved in a photo-induced, intramolecular electron transfer that quenches the fluorescence of A in response to a voltage condition. When in use, compounds of the invention are membrane-impermeant and oriented within the cell membrane such that the charged moiety localizes at the outer leaflet of the lipid bilayer and the hydrophobic moiety and molecular wire associate with the hydrophobic portion of the lipid bilayer. The rate of electron transfer, fluorescence intensity, and quenching are altered in response to changes in transmembrane potential.

A generic structure for the peptides of the present invention includes A-X-B-C, where C is a cargo moiety, the B portion includes basic amino acids, X is a cleavable linker sequence, and the A portion includes acidic amino acids. The intact structure is not significantly taken up by cells; however, upon extracellular cleavage of X, the B-C portion is taken up, delivering the cargo to targeted cells. Cargo may be, for example, a contrast agent for diagnostic imaging, a chemotherapeutic drug, or a radiation-sensitizer for therapy. X may be cleaved extracellularly or intracellularly. The molecules of the present invention may be linear, cyclic, branched, or have a mixed structure.
