[0001] Sequence Listing Description The sequence listing associated with this application is provided in text form in lieu of a written document and is hereby incorporated by reference. The text file containing the sequence listing is named 110267_402WO_SEQUENCE_LISTING.txt. The text file is 37.1 KB, was created on October 8, 2020, and was provided electronically via EFS-Web. [Background technology]

[0002] Background of the Invention Because accidental severing of neurons or nerves results in significant morbidity, preservation of human neurons and nerves is one of the most important goals of any surgical procedure. Nerves are typically identified by their elongated, whitish appearance and relationship to nearby structures or by electrophysiological testing. However, in cases of trauma, tumor involvement, inflammation, or infection, nerve identification using these criteria can be difficult. Therefore, there is a need for a method for reliably and definitively identifying neurons or nerves that overcomes the deficiencies in the art.

[0003] Identification of neurons or nerves before direct exposure during surgery, or confirmation of neuron or nerve identity after direct exposure in cases of uncertainty, is achieved by electromyography (EMG) monitoring. However, this technique has the disadvantage of not providing visual feedback to the surgeon. Thus, even if a nerve is identified at one location, either by accidental or intentional stimulation, there is no visual guide for the surgeon as to how far the nerve is from the stimulation site or the direction in which the nerve leaves the stimulation site. Furthermore, EMG tracks only motor pathways, not sensory fibers. EMG fails when neuron or nerve conduction or neuromuscular transmission is temporarily blocked somewhere far from the recording site. Such blockage can easily occur due to neuron or nerve compression, trauma, local anesthetics, or neuromuscular blocking agents.

[0004] Labeling neurons or nerves primarily relies on retrograde or anterograde tracing of individually identified axonal tracts via the use of fluorescent dyes. However, labeling neurons or nerves with locally applied fluorescent tracers has several disadvantages. First, this technique can only label one neuron or nerve fiber tract at a time, depending on the location where the dye is injected. Second, because retrograde axonal tracers typically accumulate in the neuronal cell body, this technique results in limited labeling of the fluorescent dye along the axonal tract. Third, retrograde transport is relatively slow (on the order of a few millimeters per day); therefore, it takes a long time to label human neurons or nerves, which are often longer than one meter, as in the case of sciatic neurons or nerves and their dendritic branches. Fourth, application of fluorescent dye to innervation targets, such as direct intramuscular injection to label motor neurons or nerves, is typically contaminated with varying amounts of tracer dye remaining at the injection site. Because neuron or nerve dissection relies on accurate visualization before reaching adjacent structures, a surgical site contaminated with fluorescent dye is undesirable. Finally, direct injection of the fluorescent dye itself may damage the target organ or the neuron or nerve of interest, either through mechanical injury or through very high local concentrations of dye and vehicle at the injection site. Summary of the Invention [Problem to be solved by the invention]

[0005] There is a need in the art to identify peptides that can bind to human nerves and neurons to facilitate surgical procedures and human neuroprotection.

[0006] Neurohoming peptide sequences have previously been identified for their ability to bind to mouse nerves for laboratory studies. However, the peptide sequences described in this application are identified for their ability to bind to human nerves after systemic intravenous injection into human patients, and as such, these peptides fulfill a need for peptides that can bind to human nerves more specifically and effectively than previous sequences. The present invention provides peptide sequences that selectively bind to human nerves and / or neurons, as well as methods of using such sequences in surgical procedures (e.g., to preserve nerves and / or avoid nerve damage during such procedures). [Means for solving the problem]

Both left and right sciatic nerves are shown. FAM is fluorescein conjugated to the C-terminal lysine of each peptide sequence. Images were acquired on a Zeiss Lumar.

[0170] [Figure 2] Quantification of images from Figure 1 shows that HNP401 has similar contrast (nerve fluorescence intensity / muscle fluorescence intensity) to NP41 (6.2-fold compared to 6.7-fold), with higher intensity labeling of both nerve and adjacent muscle tissue.

In vivo fluorescence images of the sciatic nerve from a 6-month-old SKH1 mouse previously intravenously injected with 450 nmol of FAM-HNP401 [approximately 48.4 mg / kg] (A) or FAM-NP41 [approximately 39 mg / kg] (B). Sciatic nerve intensity, measured and quantified in Image J, showed a 2.3-fold increase for FAM-HNP401 compared to FAM-NP41 (C). Nerve-to-muscle contrast for the two peptides was comparable: 5.79 ± 0.81 for FAM-HNP401 and 6.63 ± 1.63 for FAM-NP41 (D). In vivo fluorescence image of a rat sciatic nerve 5 hours after intravenous injection of 2 μmol of FAM-HNP401 [approximately 54 mg / kg] (E). Rat prostate nerves imaged with a real-time custom surgical imaging system (F) and a Lumar small animal microscope (G) 5 hours after intravenous injection of 2 μmol of FAM-HNP401. Blood clearance curves show the FAM signal obtained from equal volumes of blood drawn from five SKH1-Elite male mice (H). Each mouse was intravenously injected with 100 nmol [approximately 11 mg / kg] of FAM-HNP401 before blood collection at 1 minute, 10 minutes, 20 minutes, 30 minutes, 1 hour, and 2 hours.

[0187] [Figure 19] HNP401 binds to freshly viable nerves from the prostate and to the medial anteroposterior human nerve. Fluorescence imaging after topical application of 100 μM FAM-HNP401 or FAM-NP41 to 10 μm sections on cryosectioning tape from nerves within the human prostate (top row, A and B) or from the medial anteroposterior human nerve (bottom row, E and F). Nerves were imaged immediately after sectioning and application of the peptides using a confocal microscope. Immunohistochemical analysis with double labeling for neurofilament antibody SMI312 (red) and DAPI-stained nuclei (blue) of fixed sections of nerves (C and G) and corresponding H&E staining on glass slides (D and H).

[0188] [Figure 20]Comparison of cleavage sequences to determine binding efficiency. Representative fluorescence images of unfixed human sural nerves treated locally with 100 μM FAM-labeled N-2 (A), N-4 (B), N-6 (C), N-8 (D), C-2 (E), C-4 (F), C-6 (G), C-8 (H), or HNP401 (I). Due to low solubility, for local testing, C-6 had a final concentration of *73 μM, and C-8 had a final concentration of **80.6 μM. To test for improved binding, a comparison of peptide signal intensities normalized to FAM-HNP401 was performed (J). Normalized sural nerve versus temporalis muscle contrast was determined for FAM-HNP401 and FAM-HNP401-N-2 (Student's t-test, unpaired, one-tailed, p=0.011) (K).

[0189] [Figure 21]Food dyes efficiently quench FAM-NP41 bladder fluorescence. A fluorescence plate reader assay was used to demonstrate dose-dependent quenching of FAM-NP41 fluorescence. Erythrosine Extruded Blue (Santa Cruz Biotechnology, Inc.) was the most efficient quencher, achieving >80% quenching at a 2.5x dye-to-fluorescein ratio and >95% quenching at a 5x dye-to-fluorescein ratio (A). Other food dyes tested included Allura Red and Sunset Yellow. To test for in vivo quenching, we administered 50 mg / kg MW879.76 (approximately 1.5 μmol per 25 gm mouse) by direct intravenous injection to mice that had been injected with 150 nmol FAM-NP41 2 hours prior. This represents an approximately 10x dye-to-FAM-NP41 dose. Because some bladder fluorescence remained after imaging, additional dye (30 μl, 10 mM erythrosine extruder) was injected directly into the bladder. Images are shown of mouse bladders without dye quencher (B) and with the addition of erythrosine extruder (intravenously and intravesically) (C), in which bladder fluorescence was quenched to near background levels. If this method were used in human patients, dye would likely not be necessary, as bladder catheterization in the patient could be initiated once FAM-NP41 was administered and bladder fluorescence could be washed away.

Fluorescence image of periprostatic nerve bundles (white arrows) in a live male Sprague-Dawley rat imaged 15 minutes after intravenous injection of 500 nmol of NP41-TAMRA (A). Tissue was excised and cryofixed for verification of peptide fluorescent signal using confocal imaging (B) and immunohistochemistry with an antibody against TAMRA detected with horseradish peroxidase secondary and diaminobenzidine staining (C). Antibody staining against tyrosine hydroxylase was used to verify the presence of autonomic nerves (D). A non-primary negative control (E) was used.

For comparison, topical application of 100 μM of carboxy-FAM (D) and peptides screened for binding to mouse nerve NP41-FAM (E).

Images were imaged by confocal microscopy with identical parameters and leveled for comparison. **Images were enhanced 2x for visualization. Nerve-to-muscle contrast at the high concentration of 375 μM for FAM-NP41 (F and G) and FAM-HNP401 (H and I). Images were imaged by confocal microscopy and leveled for direct comparison. Mouse facial nerve (red arrow) with surrounding muscle treated with 375 μM (J) or 100 μM (K) FAM-NP41 or 375 μM (L) or 100 μM (M) FAM-HNP401. The lower image is equivalent and was acquired with a Lumar imaging scope using the same parameters. FAM-HNP401 shows high muscle binding in mouse tissue with lower contrast compared to FAMNP41. High-resolution confocal images of a low concentration of FAM-HNP401 (10 μM) on a human nerve show binding of the peptide to non-axonal structural components of the nerve (N).

Topical application of 100 μM FAM-HNP401 (A) or buffer alone (B) onto a 10 μm section of unfixed human sural nerve, followed by imaging using a confocal microscope under identical acquisition parameters for direct comparison. Images were leveled evenly using Image J and subsequently brightened 16x compared to (B) for visualization.

[0195] [Figure 27] Mass spectrometry analysis of urine samples from mice injected with a neuronal-binding peptide. Fragmentation ion peaks from cysteine-FAM collected from the urine of mice injected with FAM-HNP401 indicate that the peptide is metabolized (A). Similar results were obtained in mice injected with FAM-NP41 (B). However, the peptide, made with d-amino acids, is detectable in the urine and not metabolized in mice injected with FAM-dNP41 (C).

[0200] II. Definition In this description, any concentration range, percentage range, ratio range, or integer range should be understood to include any integer value within the recited range and, where appropriate, fractions thereof (such as 1 / 10 and 1 / 100 of an integer), unless otherwise indicated. Also, any numerical range recited herein relating to any physical characteristic, such as polymer subunits, size, or thickness, should be understood to include any integer within the recited range, unless otherwise indicated. As used herein, the term "about" means ±20% of the indicated range, value, or structure, unless otherwise indicated.

[0201] As used herein, the terms "a" and "an" should be understood to refer to "one or more" of the listed components. The use of alternatives (e.g., "or") should be understood to mean either one, both, or any combination thereof of the alternatives.

[0202] In addition, it should be understood that each individual compound or group of compounds derived from the various combinations of structures and substituents described herein is disclosed by this application to the same extent as if each compound or group of compounds were individually described, and thus selection of a particular structure or particular substituents is within the scope of this disclosure.

[0203] As used herein, the following terms have the meanings ascribed to them unless specified otherwise.

[0204] The central nervous system (CNS) consists of the brain and spinal cord and the retina.

[0205] The peripheral nervous system (PNS) extends outside the CNS. The PNS is divided into the somatic nervous system and the autonomic nervous system.

[0206] Neurons are electrically excitable cells that process and transmit information by electrical and chemical signaling.

[0207] A typical neuron has a cell body (often called the soma), dendrites, and an axon.

[0208] Nerves are enclosed cable-like bundles of nerve axons. Each nerve is a cord-like structure containing many axons. Each axon is surrounded by a layer of tissue called the endoneurium. Axons are organized into groups called fascicles, and each fascicle is surrounded by a layer of tissue called the perineurium. Neurons, or nerves, are surrounded by a layer of tissue called the epineurium.

[0209] As used herein, the term "targeting molecule" refers to any agent (e.g., a peptide, protein, nucleic acid polymer, aptamer, or small molecule) that specifically binds to a target of interest. In some embodiments, the targeting molecule comprises a peptide, also referred to herein as a "targeting peptide." The target of interest can be a tissue, a cell type, a cellular structure (e.g., an organelle), a protein, a peptide, a polysaccharide, or a nucleic acid polymer. In some embodiments, the targeting molecule is any agent that specifically binds to one or more neurons or nerves of a subject. In some embodiments, the targeting molecule further comprises a cargo (e.g., a drug, a fluorescent label, or a photosensitizer).

[0210] As used herein, the term "aptamer" refers to an oligonucleotide (e.g., DNA, RNA, or XNA) molecule selected from a random pool based on its ability to bind to other molecules with high affinity specificity based on non-Watson-Crick interactions with the target molecule (see, e.g., Cox and Ellington, Bioorg. Med. Chem. 9:2525-2531 (2001), Lee et al., Nuc. Acids Res. 32:D95-D100 (2004)). Alternatively, the term refers to a short peptide (e.g., 5-20 amino acids) embedded as a loop within a stable protein scaffold rather than as a free peptide. Aptamers can be selected to bind to nucleic acids, proteins, small organic compounds, vitamins, inorganic compounds, cells, and even whole organisms. In some embodiments, the targeting peptide can comprise an aptamer, or the targeting molecule peptide sequence can be in the form of a peptide aptamer.

[0211] The terms "polypeptide," "peptide," and "protein" are used interchangeably herein to refer to a polymer of amino acid residues. These terms apply to naturally occurring amino acid polymers and amino acid polymers in which one or more amino acid residues are non-naturally occurring amino acids (e.g., amino acid analogs). These terms encompass amino acid chains of any length, including full-length proteins (i.e., antigens), in which the amino acid residues are linked by covalent peptide bonds. As used herein, the term "peptide" refers to a polymer of amino acid residues, typically ranging in length from 2 to about 50 residues. In certain embodiments, peptides range in length from about 2, 3, 4, 5, 7, 9, 10, or 11 residues to about 50, 45, 40, 45, 30, 25, 20, or 15 residues. In certain embodiments, peptides range in length from about 8, 9, 10, 11, or 12 residues to about 15, 20, or 25 residues. When amino acid sequences are provided herein, L-, D-, or beta-amino acid versions of the sequence are also contemplated, as are retro, inversion, and retro-inversion isoforms. Peptide also includes amino acid polymers and naturally occurring amino acid polymers, in which one or more amino acid residues are artificial chemical analogs of corresponding naturally occurring amino acids.In addition, the term also covers the amino acid that is linked by peptide bond or other modified bond (for example, when peptide bond is replaced by α-ester, β-ester, thioamide, phosphonamide, carbamate, hydroxylate, etc. (see, for example, Spatola, (1983) Chem. Biochem. Amino Acids and Proteins 7:267-357), when amide is replaced by saturated amine (see, for example, Skiles et al., U.S. Patent No. 4,496,542, and Kaltenbronn et al., (1990) Pp.969-970 in Proc. 11th American Peptide Symposium, ESCOM Science Publishers, The Netherlands, etc.), which are incorporated herein by reference).

[0212] The term "amino acid" refers to naturally occurring and synthetic amino acids, as well as amino acid analogs and amino acid mimetics that function in a manner similar to naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those that are later modified, such as hydroxyproline, γ-carboxyglutamate, and O-phosphoserine. Amino acids may be L- or D-amino acids. Amino acid analogs refer to compounds that have the same basic chemical structure as naturally occurring amino acids, i.e., carbons bonded to hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, and methionine sulfoxide. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as naturally occurring amino acids. Amino acid mimetics refer to chemical compounds that have a structure different from the general chemical structure of amino acids but function similarly to naturally occurring amino acids.

[0213] Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUP AC-IUB Biochemical Nomenclature Commission. Similarly, nucleotides may be referred to by their commonly accepted one-letter codes.

[0214] Those skilled in the art will recognize that individual substitutions, deletions, or additions to peptide, polypeptide, or protein sequences that alter, add, or delete a single amino acid or a small percentage of amino acids in the encoded sequence are "conservatively modified variants," where the alteration results in the replacement of an amino acid with a chemically similar amino acid. Conservative substitution tables providing functionally similar amino acids are well known in the art. Such conservatively modified variants are in addition to, and do not exclude, polymorphic variants, interspecies homologs, and alleles of the present invention.

[0215] The following eight groups contain amino acids that are conservative substitutions for each other: 1) alanine (A), glycine (G), 2) aspartic acid (D), glutamic acid (E), 3) asparagine (N), glutamine (Q), 4) arginine (R), lysine (K), 5) isoleucine (I), leucine (L), methionine (M), valine (V), 6) phenylalanine (F), tyrosine (Y), tryptophan (W), 7) serine (S), threonine (T), and 8) cysteine ​​(C), methionine (M) (see, e.g., Creighton, Proteins (1984)).

[0216] " sequence identity " as used herein refers to the percentage of amino acid residues in a single sequence that are identical to the amino acid residues in another reference polypeptide sequence, after aligning the sequence and introducing gaps as necessary to achieve the maximum sequence identity percentage, and does not take into account any conservative substitutions as part of sequence identity.Sequence identity percentage value can be determined by using the NCBI BLAST 2.0 software defined by Altschul et al. (1997), Nucl. Acids Res. 25:3389-3402, with parameters set to default.

[0217] As used herein, the term "label" refers to a molecule that facilitates visualization and / or detection of a targeting molecule disclosed herein. In some embodiments, the label is a fluorescent moiety.

[0218] The phrase "specifically bind" refers to the interaction between the targeting molecule disclosed herein and a target (e.g., purified protein, neuron or nervous tissue, neuron or nerve, brain neuron or nerve, central neuron or nerve, myelinated or unmyelinated neuron or nerve, or the connective tissue surrounding a neuron or nerve), and refers to the formation of a high affinity bond between the targeting molecule and the target.Furthermore, the term means that the targeting molecule has a low affinity for non-targets.

[0219] "Selective binding," "selectivity," and the like refer to the preference of an agent to interact with one molecule compared to another molecule. Preferably, the interaction between the targeting molecule disclosed herein and the target is specific and selective. Note that in some embodiments, the agent is designed to "specifically bind" and "selectively bind" two distinct but similar targets without binding to other undesired targets.

[0220] The terms "individual," "patient," or "subject" are used interchangeably. As used herein, they refer to any mammal (i.e., a species of any order, family, and genus within the taxonomic classification Animalia: Chordata: Vertebrates: Mammalia). In some embodiments, the mammal is a cow, horse, sheep, pig, cat, dog, goat, mouse, rat, rabbit, guinea pig, non-human primate, or human. None of these terms require, and are not limited to, a status under the care (e.g., permanent or temporary) of a health care professional (e.g., a physician, registered nurse, student nurse, physician assistant, ward assistant, or hospice worker).

[0221] As used herein, the terms "administer," "administering," "administration," and the like refer to methods that can be used to enable delivery of an agent or composition to a desired site of biological action. These methods include, but are not limited to, parenteral injection (e.g., intravenous, subcutaneous, intraperitoneal, intramuscular, intravascular, intrathecal, intravitreal, infusion, or topical). Administration techniques optionally used with the agents and methods described herein include those discussed, for example, in Goodman and Gilman, The Pharmacological Basis of Therapeutics, current ed.; Pergamon; and Remington's, Pharmaceutical Sciences (current edition), Mack Publishing Co., Easton, Pa. In some embodiments, administration is via systemic intravenous injection into a human patient.

[0222] As used herein, the term "pharmaceutically acceptable" refers to a material that does not abolish the biological activity or properties of the agents described herein and is relatively non-toxic (i.e., the toxicity of the material significantly outweighs the benefits of the material). In some cases, a pharmaceutically acceptable material can be administered to an individual without causing significant undesirable biological effects or interacting significantly adversely with any of the components of the composition in which it is contained.

[0223] The term "surgery" as used herein refers to any method that can be used to manipulate, alter, or cause an effect by physical intervention. These methods include, but are not limited to, open surgery, endoscopic surgery, laparoscopic surgery, minimally invasive surgery, robotic surgery, any procedure that can affect any neuron or nerve, such as placement of a retractor during spinal surgery, cardiac neuron or nerve ablation, epidural injection, intrathecal injection, neuron or nerve block, implantation of a device such as a neuron or nerve stimulator, and implantation of a pump. In some embodiments, the subject of surgery is a human subject or patient.

[0224] III. Target Disclosed herein, in identified embodiments, are human neuronal and / or neural targeting molecules that specifically bind to human neurons or neural targets.

[0225] In some embodiments, the target is a human neuron or nerve. The nerve can be any human nerve (e.g., motor nerve, sensory nerve, sympathetic and parasympathetic nerve, periprostatic neurovascular bundle, sciatic nerve, cranial nerve including the olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, hypoglossal nerve, spinal nerve, brachial plexus, or lumbosacral plexus). The neuron can be any neuron (e.g., sensory neuron (afferent neuron), motor neuron (efferent neuron), interneuron, unipolar neuron, bipolar neuron, multipolar neuron, basket cell, Betz cell, medium spiny neuron, Purkinje cell, pyramidal cell, Renshaw cell, granule cell, anterior horn cell). In some embodiments, the human neuron or nerve is myelinated. In some embodiments, the neuron or nerve is unmyelinated. In some embodiments, the human neuron or nerve is demyelinated. In some embodiments, the human neuron or nerve is undergoing demyelination.

[0226] In some embodiments, the neuron and / or neural target is a human neuron or neural component. The human neuron or neural component is any component of a neuron or nerve. In some embodiments, the target is tissue within or surrounding a neuron or nerve (e.g., epineurium, perineurium, or endoneurium). In some embodiments, the target is a component of myelin (e.g., myelin basic protein (MBP), myelin oligodendrocyte glycoprotein, or proteolipid protein). In some embodiments, the target is expressed by Schwann cells (e.g., MBP, glial fibrillary acidic protein, S-100, or myelin protein zero). In some embodiments, the target is a component of neuron or neural tissue (e.g., elastin, fibrillin, e-cadherin, cytokeratin, vimentin, collagen I, collagen III, collagen IV, or collagen V). In some embodiments, the target is a neurotrophic factor receptor expressed in neurons or nerves (e.g., tyrosine kinase receptors TrkA, TrkB, and TrkC, low-affinity neuronal or nerve growth receptors or p75 neurotrophin receptors, or GDNF family receptors alpha-1 or -2). In some embodiments, the target is a non-neurotrophic factor receptor expressed in neurons or neural tissue (e.g., epidermal growth factor receptor, transforming growth factor beta receptor, vascular endothelial growth factor receptor, endothelin A receptor, endothelin B receptor, and integrin receptors).

[0227] Determining whether a neuron and / or neural targeting molecule can bind to human neurons or nerves or their components can be achieved by any suitable method. In some embodiments, the method for determining whether a neuron and / or neural targeting molecule can bind to human neurons or nerves or their components comprises contacting a targeting molecule (e.g., peptide or aptamer) disclosed herein with a test agent for a sufficient time to allow the targeting molecule and the test agent to form a binding complex. The binding complex is detected using any suitable method. Suitable binding assays can be performed in vitro or in vivo, including but not limited to, phage display, two-hybrid screen, co-precipitation, cross-linking and expression cloning (see, for example, Bennett, JP and Yamamura, HI (1985) "Neurotransmitter, Hormone or Drug Receptor Binding Methods," in Neurotransmitter Receptor Binding (Yamamura, HL, et al., eds.), pp.61-89). Other binding assays involve the use of mass spectrometry or NMR techniques to identify molecules bound to a target of interest. The targeting molecules utilized in such assays can be naturally expressed, cloned, or synthetic.

[0228] In some embodiments, the targeting molecule is capable of crossing the blood-brain barrier to reach and bind to a human neuron or nerve of interest.

[0294] As used herein, a "linker" refers to any molecule that can be (e.g., covalently) linked to a targeting molecule disclosed herein. Linkers include, but are not limited to, straight-chain or branched-chain carbon linkers, heterocyclic carbon linkers, amino acid linkers (e.g., D- or L-amino acids), lipophilic residues, peptide linkers, peptide nucleic acid linkers, hydrazone linkers, SPDB disulfide, sulfo-SPDB, maleimidomethylcyclohexane-1-carboxylate (MCC), aminohexanoic acid linkers, and polyether linkers (e.g., PEG). For example, poly(ethylene glycol) linkers are available from Quanta Biodesign, Powell, OH. These linkers optionally have an amide bond, a sulfhydryl bond, or a heterofunctional bond.

[0295] In some embodiments, the linker is attached to a targeting molecule disclosed herein by a covalent bond, which in some embodiments comprises an ether bond, a thioether bond, an amine bond, an amide bond, a carbon-carbon bond, a carbon-nitrogen bond, a carbon-oxygen bond, or a carbon-sulfur bond.

[0296] In some embodiments, the linker is flexible. In some embodiments, the linker is rigid.

[0297] In some embodiments, the linker comprises a linear structure. In some embodiments, the linker comprises a non-linear structure. In some embodiments, the linker comprises a branched structure. In some embodiments, the linker comprises a cyclic structure.

[0298] In some embodiments, the linker is alkyl. In some embodiments, the linker is heteroalkyl.

[0299] In some embodiments, the linker is an alkylene. In some embodiments, the linker is an alkenylene. In some embodiments, the linker is an alkynylene. In some embodiments, the linker is a heteroalkylene.

[0300] An "alkyl" group refers to an aliphatic hydrocarbon group. The alkyl portion can be a saturated or unsaturated alkyl. Depending on the structure, an alkyl group can be a monoradical or a diradical (i.e., an alkylene group).

[0301] An "alkyl" moiety may have 1 to 10 carbon atoms (wherever it appears herein, a numerical range such as "1 to 10" refers to each integer in the specified range; for example, "1 to 10 carbon atoms" means that the alkyl group can be composed of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to 10 carbon atoms, although this definition also covers "alkyl" without a specified numerical range). An alkyl group can also be a "lower alkyl" having 1 to 6 carbon atoms. The alkyl group of the compounds described herein may be designated as "C1-C4 alkyl" or similar terminology. By way of example, "C1-C4 alkyl" indicates that there are 1 to 4 carbon atoms in the alkyl chain, and the alkyl chain is selected from methyl, ethyl, propyl, isopropyl, n-butyl, iso-butyl, sec-butyl, and t-butyl. Typical alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, hexyl, ethenyl, propenyl, butenyl, and the like.

[0302] In some embodiments, the linker comprises a ring structure (e.g., aryl). As used herein, the term "ring" refers to a structure optionally closed by a covalent bond. Rings include, for example, carbocycles (e.g., aryl and cycloalkyl), heterocycles (e.g., heteroaryl and non-aromatic heterocycles), aromatic rings (e.g., aryl and heteroaryl), and non-aromatic rings (e.g., cycloalkyl and non-aromatic heterocycles). Rings can be optionally substituted. Rings can be monocyclic or polycyclic.

[0303] As used herein, the term "aryl" refers to an aromatic ring in which each atom forming the ring is a carbon atom. The aryl ring can be formed by 5, 6, 7, 8, 9, or more than 9 carbon atoms. The aryl group can be optionally substituted. Examples of aryl groups include, but are not limited to, phenyl, naphthalenyl, phenanthrenyl, anthracenyl, fluorenyl, and indenyl. Depending on the structure, the aryl group can be a monovalent group or a divalent group (i.e., an arylene group).

[0304] The term "cycloalkyl" refers to a monocyclic or polycyclic non-aromatic radical in which each of the atoms forming the ring (i.e., skeletal atoms) is a carbon atom. Cycloalkyls can be saturated or partially unsaturated. Cycloalkyl groups include groups having 3 to 10 ring atoms. Cycloalkyls include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl.

[0305] In some embodiments, the ring is a cycloalkane. In some embodiments, the ring is a cycloalkene.

[0306] In some embodiments, the ring is an aromatic ring. The term "aromatic" refers to a planar ring having a delocalized π-electron system containing 4n+2 π-electrons, where n is an integer. An aromatic ring can be formed from 5, 6, 7, 8, 9, or more than 9 atoms. An aromatic can be optionally substituted. The term "aromatic" includes both carbocyclic aryl (e.g., phenyl) and heterocyclic aryl (or "heteroaryl" or "heteroaromatic") groups (e.g., pyridine). The term includes monocyclic or fused-ring polycyclic (i.e., rings that share adjacent pairs of carbon atoms) groups.

[0307] In some embodiments, the ring is a heterocycle. The term "heterocycle" refers to heteroaromatic and heteroalicyclic groups containing 1 to 4 heteroatoms selected from O, S, and N, respectively, where each heterocyclic group has 4 to 10 atoms in its ring system, provided that the ring of the group does not contain two adjacent O or S atoms. Non-aromatic heterocyclic groups include groups having only 3 atoms in their ring system, while aromatic heterocyclic groups must have at least 5 atoms in their ring system. Heterocyclic groups include benzo-fused ring systems. An example of a 3-membered heterocyclic group is aziridinyl. An example of a 4-membered heterocyclic group is azetidinyl (derived from azetidine). An example of a 5-membered heterocyclic group is thiazolyl. An example of a 6-membered heterocyclic group is pyridyl, and an example of a 10-membered heterocyclic group is quinolinyl. Examples of non-aromatic heterocyclic groups are pyrrolidinyl, tetrahydrofuranyl, dihydrofuranyl, tetrahydrothienyl, tetrahydropyranyl, dihydropyranyl, tetrahydrothiopyranyl, piperidino, morpholino, thiomorpholino, thioxanyl, piperazinyl, azetidinyl, oxetanyl, thietanyl, homopiperidinyl, oxepanyl, thiepanyl, oxazepinyl, diazepinyl, thiazepinyl, 1,2,3,6-tetrahydropyran ... These include lysinyl, 2-pyrrolinyl, 3-pyrrolinyl, indolinyl, 2H-pyranyl, 4H-pyranyl, dioxanyl, 1,3-dioxolanyl, pyrazolinyl, dithianyl, dithiolanyl, dihydropyranyl, dihydrothienyl, dihydrofuranyl, pyrazolidinyl, imidazolinyl, imidazolidinyl, 3-azabicyclo[3.1.0]hexanyl, 3-azabicyclo[4.1.0]heptanyl, 3H-indolyl, and quinolizinyl.Examples of aromatic heterocyclic groups are pyridinyl, imidazolyl, pyrimidinyl, pyrazolyl, triazolyl, pyrazinyl, tetrazolyl, furyl, thienyl, isoxazolyl, thiazolyl, oxazolyl, isothiazolyl, pyrrolyl, quinolinyl, isoquinolinyl, indolyl, benzimidazolyl, benzofuranyl, cinnolinyl, indazolyl, indolizinyl, phthalazinyl, pyridazinyl, triazinyl, isoindolyl, pteridinyl, purinyl, oxadiazolyl, thiadiazolyl, furazanyl, benzofurazanyl, benzothiophenyl, benzothiazolyl, benzoxazolyl, quinazolinyl, quinoxalinyl, naphthyridinyl and fallopyridinyl. The aforementioned groups can be C-bonded or N-bonded where possible. For example, a group derived from pyrrole can be pyrrol-1-yl (N-bonded) or pyrrol-3-yl (C-bonded). Furthermore, groups derived from imidazole can be imidazol-1-yl or imidazol-3-yl (both N-linked) or imidazol-2-yl, imidazol-4-yl, or imidazol-5-yl (all C-linked). Heterocyclic groups include benzo-fused ring systems and ring systems substituted with one or two oxo groups (=0), such as pyrrolidin-2-one. Depending on the structure, heterocyclic groups can be monovalent or divalent (i.e., heterocyclene groups).

[0308] In some embodiments, the rings are fused. The term "fused" refers to a structure in which two or more rings share one or more bonds; in some embodiments, the rings are dimers. In some embodiments, the rings are trimers. In some embodiments, the rings are substituted.

[0309] The term "carbocyclic" or "carbocycle" refers to a ring in which each of the atoms forming the ring is a carbon atom. Carbocycles include aryls and cycloalkyls. Thus, the term distinguishes between carbocycles and heterocycles ("heterocyclic") in which the ring backbone contains at least one atom other than carbon (i.e., a heteroatom). Heterocycles include heteroaryls and heterocycloalkyls. Carbocycles and heterocycles can be optionally substituted.

[0310] In some embodiments, the linker is substituted. The term "optionally substituted" or "substituted" means that the recited groups can be individually and independently substituted with one or more additional groups selected from C-Ce alkyl, C-Cg cycloalkyl, aryl, heteroaryl, C-C heteroalicyclic, hydroxy, C-C alkoxy, aryloxy, C-C alkylthio, arylthio, C-C alkylsulfoxide, arylsulfoxide, C-C alkylsulfone, arylsulfone, cyano, halo, C-C acyl, C-C acyloxy, nitro, C-C haloalkyl, C-C fluoroalkyl, and amino, including C-C alkylamino, and protected derivatives thereof. By way of example, the optional substituents may be L or R, where each L is independently selected from a bond, -O-, -C(=O)-, -S-, -S(=O)-, -S(O)2-, -NH-, -NHC(O)-, -C(O)NH-, S(O)2NH-, -NHS(O)2-, -OC(O)NH-, -NHC(O)O-, -(CpC6 alkyl)-, or -(C2-C6 alkenyl)-, and each R is independently selected from H, (C1-C4 alkyl), (C3-C8 cycloalkyl), heteroaryl, aryl, and C1-C6 heteroalkyl. Optionally substituted non-aromatic groups may be substituted with one or more oxo (=O). Protecting groups that may form the protective derivatives of the above substituents are known to those of skill in the art.

[0311] In some embodiments, a bifunctional linker is used to form the desired conjugate, with one functional group reactive with a group on one molecule (e.g., a targeting molecule) and another reactive group on the other molecule (e.g., a fluorescent moiety or a drug). Alternatively, in some embodiments, derivatization is performed to provide the functional groups. Thus, for example, procedures for generating free sulfhydryl groups on peptides are also known (see U.S. Pat. No. 4,659,839). Alternatively, the linker may include a heterobifunctional crosslinker containing two or more different reactive groups that form a heterocycle that can interact with the targeting molecule. For example, a heterobifunctional crosslinker such as cysteine ​​may contain an amine-reactive group, and a thiol-reactive group can interact with an aldehyde on a derivatized targeting molecule. Additional combinations of reactive groups suitable for heterobifunctional crosslinkers include, for example, amine and sulfhydryl reactive groups, carbonyl and sulfhydryl reactive groups, amine and photoreactive groups, sulfhydryl and photoreactive groups, carbonyl and photoreactive groups, carboxylate and photoreactive groups, and arginine and photoreactive groups. Examples of heterobifunctional crosslinkers include N-succinimidyl 4-(2-pyridyldithio)butanoate (SPDB) and maleimidomethylcyclohexane-1-carboxylate (MCC).

[0312] In some embodiments, a peptide linker consisting of one or more amino acids is used to connect the targeting molecule and the fluorescent moiety or drug. Generally, peptide linkers have no specific biological activity other than connecting molecules or maintaining a minimum distance or other spatial relationship between molecules. However, the constituent amino acids of the linker can be selected to affect certain properties of the molecule, such as folding, net charge, or hydrophobicity. In some embodiments, the peptide linker is relatively short, typically less than about 10 amino acids, preferably less than about 8 amino acids, and more preferably less than 5 amino acids. Non-limiting illustrative examples include glycine and glycine-serine linkers, which can be added to the C-terminus of the targeting peptide. In some embodiments, the peptide linker is a glycine-glycine-glycine-cysteine ​​(GGGC) linker, a glycine-glycine-cysteine ​​(GGC) linker, a glycine-glycine (GG) linker, or a cysteine ​​(C) linker. In some embodiments, a GGGC, GGC, GG, or C linker is added to the C-terminus of the targeting peptide.

[0338] The human neuron targeting or human neural targeting molecules described herein may further comprise a cargo. In some embodiments, the cargo comprises a fluorescent moiety, a drug, a photosensitizer, or a combination thereof. In some embodiments, the fluorescent moiety comprises a fluorophore, a fluorescent dye, a fluorescent protein, a fluorescent peptide, or any combination thereof.

[0339] In certain embodiments, the cargo comprises a fluorescent moiety, such as a fluorophore, fluorescent dye, fluorescent protein, fluorescent peptide, or any combination thereof. In such embodiments, the human neuron-targeting or human neural targeting molecule described herein can be administered to a human patient (e.g., by systemic intravenous injection) along with the cargo. After administration, or after a sufficient time for the human neuron-targeting or human neural targeting molecule described herein to bind to pulmonary nerves, the cargo is illuminated through the bronchial wall in the lung. In certain embodiments, a bronchoscope, catheter, or other device can be inserted into one or both bronchi of the patient's lung. The bronchoscope, catheter, or other device can include a light source that generates light inside the lung and / or a light source that generates light outside the lung and an optical fiber for delivering the light generated in the lung. Such a configuration can be activated to illuminate the inner walls of the bronchi through part or all of the patient's lung. Such illumination causes the cargo bound to the pulmonary nerves to fluoresce, such as behind and / or through the bronchial wall. The bronchoscope may also include a photoreceptive or photosensitive device that receives light emitted by cargo within the lung, such as through and / or from the wall of the bronchus, or an optical fiber that delivers such light outside the lung, and a photoreceptive or photosensitive device for receiving light outside the lung.

[0340] In a further embodiment, the light generated by the cargo and received by the bronchoscope arrangement can be used to map, such as computer-aided imaging or digital mapping, the location of one or both bronchi of a patient's lungs, and particularly the nerves surrounding the bronchi. Such images or maps can then be used to identify pulmonary nerves during lung surgery or operation of an irradiation and / or ablation system and during irradiation and / or ablation of nerves mapped by such a system. Such irradiation and ablation can be performed using non-ionizing radiation, such as electromagnetic radiation, radiofrequency ablation (RFA), cryoablation, photodynamic therapy (e.g., photosensitizers), and microwave ablation, or any other suitable technique described herein.

[0341] Robotic systems are commercially available to assist in the performance of such irradiation, imaging, mapping, and image- or map-guided procedures. As an example, Medtronic and / or Covidien offer systems available under the SUPERDIMENSION trade name, details of which are available as of October 9, 2019, at the following URL: https: / / www.medtronic.com / covidien / en-us / products / interventional-lung-solutions / superdimension-navigation-system.html. The information provided on this webpage describes the SUPERDIMENSION system as "a navigation system that uses fluoroscopic navigation technology," explains that "electromagnetic navigation bronchoscopy (ENB) is a minimally invasive approach to access hard-to-reach areas of the lung," and states that "SUPERDIMENSION TM The navigation system "displays an image of the tracheobronchial tree that helps the physician guide endoscopic tools or catheters in the respiratory tract and allows for the placement of markers in the soft tissue of the lungs."

[0342] In other embodiments, the cargo comprises a photosensitizer. When exposed to light of a distinguishing wavelength, such agents react with molecular oxygen to produce highly cytotoxic singlet oxygen. In such embodiments, the human neuron-targeting or human neural targeting molecules described herein can be administered to a patient (e.g., by systemic intravenous injection) along with the cargo. After administration, or after a sufficient time for the human neuron-targeting or human neural targeting molecules described herein to bind to pulmonary nerves, a bronchoscope, catheter, or other device can be inserted into one or both bronchi of the patient's lungs. The bronchoscope can include a light source that generates light inside the lungs and / or a light source that generates light outside the lungs and an optical fiber for delivering the light generated in the lungs. Such a configuration can be activated to illuminate the inner walls of the bronchi through part or all of the patient's lungs.

[0343] Such illumination travels through the bronchial walls and activates cargo bound to pulmonary nerves via human neuron-targeting or human neural targeting molecules, which react with molecular oxygen to produce highly cytotoxic singlet oxygen, thereby localizing nerve injury or ablation. Therefore, such photosensitizers may be referred to as "ablation agents." An optimal light dose can be identified to maximize nerve killing while minimizing damage to adjacent tissue. Such techniques may be referred to as "photo-induced ablation therapy." The commercially available robotic lung navigation systems described herein, available from Medtronic and / or Covidien, may assist in the implementation of such techniques.

[0344] Using the techniques described herein with respect to Section XIV, nerves within a patient's body can be labeled, mapped, and ablated. Such nerves surround the patient's lungs and can be accessed throughout the patient's lungs via the bronchi, as in the treatment of chronic obstructive pulmonary disease (COPD). Cholinergic parasympathetic nerves innervate both large and small airway nerves and provide the predominant innervation of the human lung. Pulmonary parasympathetic activity is enhanced in COPD. Therefore, blocking parasympathetic activity in the lungs can have a therapeutic effect in the treatment of COPD.

[0345] As another example, the human neuron-targeting or human neural targeting molecules described herein, optionally further comprising a cargo, are used to label renal nerves. The human neuron-targeting or human neural targeting molecules described herein, together with the cargo, can be administered to a human patient (e.g., by systemic intravenous injection). After administration, or after a sufficient time for the human neuron-targeting or human neural targeting molecules described herein to bind to renal nerves, the cargo is illuminated through the wall of the renal artery within the kidney. In a specific embodiment, a catheter or other device can be inserted into the renal vasculature (e.g., the renal artery). The catheter or other device can include a light source that generates light within the renal artery and / or a light source that generates light outside the kidney and an optical fiber for delivering the light generated outside the kidney. Such a configuration can be activated to illuminate the inner wall of the renal artery. Such illumination causes cargo bound to sympathetic nerves within the renal artery to fluoresce, such as behind and / or through the wall of the renal artery. The catheter may include a photoreceptive or photosensitive device for receiving light generated by cargo within the kidney through and / or from the wall of the renal artery or an optical fiber for delivering such light to the kidney and a photoreceptive or photosensitive device for receiving light outside the kidney.

[0346] In a further embodiment, light emitted by the cargo and received by the catheter configuration can be used to image or generate maps, such as computer-assisted digital maps, of the location of the patient's kidneys, particularly the sympathetic nerves around the renal arteries. Such images or maps can then be used to mark and identify renal nerves during renal surgery or operation of an irradiation and / or ablation system and irradiation and / or ablation of the nerves mapped by such a system. Such irradiation and ablation can be performed using non-ionizing radiation, such as electromagnetic radiation, radiofrequency ablation (RFA), cryoablation, photodynamic therapy (e.g., photosensitizers), and microwave ablation, or any other suitable technique described herein. Catheter systems for renal ablation are commercially available, for example, the Symplicity Spyral catheter available from Medtronic, Inc. TM Renal Denervation Catheter; EnligHTN from St. Jude Medical TM Renal Denervation System, One-Shot from Covidien TM Renal denervation system; and Vessix from Boston Scientific TM There is a renal denervation system.

[0355] In some embodiments, the human neuronal or neural targeting molecule is administered to the human subject by systemic intravenous injection. [Example]

[0356] Example 1: Peptides for targeting human nerves and their use in image-guided surgery, diagnostics, and therapeutic delivery overview A phage display screen was used to identify peptides that bind to human nerves and may therefore be useful for whole-body in vivo labeling of nerves during fluorescence-assisted surgery. Specifically, an m13 phage library (Creative Biolabs) expressing a 16-amino acid sequence randomly located at the N-terminus of gIII was processed by selection for binding to freshly excised or frozen human nerves. In parallel, a newly designed NP41 X12+4 library was screened. Each library was processed through up to six binding and washing cycles. Selected phages were further counterselected for high-affinity binding to tissues by pre-absorb- ing the library to muscle and adipose tissues, which have low affinity, prior to positive selection for nerve binding. Sequencing of individual phages yielded unique sequences that were highly enriched and therefore had higher affinity than the pool of clones: SGQVPWEEPYYVVKKSS (HNP401; SEQ ID NO: 1), WEYHYVDLNWTSQHPQ (HNP402; SEQ ID NO: 2), DLPDIIWDFNWETA (HNP403; SEQ ID NO: 3) from the X16 library, and DTHAHAKPRVPAFKSV (HNP404; SEQ ID NO: 16) from the NP41-X12+4 library. Amino acid sequences derived from the sequences of selected phages were chemically synthesized as peptides by solid-phase synthesis and labeled with fluorescein (FAM) or Cy5 at the C-terminus via a GGC linker for in vitro binding to human nerves and in vivo labeling of rodent nerves. Strong labeling of human nerves and fresh sections of in vivo labeled mouse sciatic nerves was demonstrated. Useful labeling occurred 2-6 h after intravenous administration and could be visualized using a customized fluorescent dissecting microscope, a Maestro imager from CRI or a Zeiss Lumar.

[0357] Preservation of peripheral nerves is one of the most important goals of any surgical procedure, as accidental severing of peripheral nerves during surgical procedures results in significant morbidity for patients. Furthermore, nerves grow back more slowly and incompletely after severing than almost all other tissues. Typically, peripheral nerves are identified by their relatively constant relationship to nearby structures and their typical appearance as elongated, whitish, shiny structures. However, in many cases, identifying peripheral nerves using these criteria can be difficult, for example, in cases of tumor involvement, inflammation / infection, a previously operated surgical field, or when the nerve is encased in bone.

[0358] Current methods for nerve labeling primarily rely on retrograde or anterograde tracing of individually identified axonal tracts through the use of fluorescent dyes. The fluorescent dye is either applied to an innervation target and travels retrogradely to label the innervating nerve fibers, or it is applied directly to an identified nerve, labeling nerve fibers both anterogradely and retrogradely. This technique has the drawback of only being able to label one nerve fiber tract at a time, which depends on the location of the dye injection. A second drawback is that retrograde axonal tracers typically accumulate in the neuronal cell body, limiting axonal labeling by these fluorescent dyes, resulting in limited accumulation of the fluorescent dye along the axonal tract. A third disadvantage of this technique is that retrograde transport is relatively slow (on the order of several millimeters per day), thus requiring a long time to label human nerves that are often longer than one meter (as in the case of the sciatic nerve and its dendritic branches). Furthermore, application of fluorescent dye to innervation targets, such as direct intramuscular injection to label motor nerves, is typically contaminated with variable amounts of tracer dye remaining at the injection site. Because nerve dissection depends on accurate visualization of adjacent structures before encountering them, a surgical site that is contaminated with fluorescent dye is undesirable. Finally, direct injection of the fluorescent dye itself may damage the target organ or nerve of interest, either through mechanical injury or through very high local concentrations of dye and vehicle at the injection site.

[0359] The method of systemic injection of fluorescently labeled peptides to label nerves described herein addresses all of the disadvantages of fluorescent tracers mentioned above. First, because the peptides are delivered systemically, all peripheral nerves in the body can potentially be labeled. This contrasts with current methods, which label only one nerve at a time. Second, because the peptides described herein are selected for their ability to bind to nerves, nerve fibers are clearly visualized relative to adjacent non-neuronal structures. This contrasts with the preferential accumulation in neuronal cell bodies rather than axons that occurs with most current fluorescent dyes. Third, binding of the peptides described herein to nerves is very rapid, and visualization of peripheral nerves using this technique can be achieved within a few hours. This contrasts with the relatively slow rate of labeling with anterograde or retrograde tracers. Finally, because the peptides are applied systemically via intravenous injection, damage to nerves at the injection site is not an issue.

[0360] Neurohoming peptide sequences derived using mouse peripheral nerves for laboratory studies have been previously described (U.S. Patent No. 8,685,372, April 1, 2014). However, because the intended ultimate clinical application of neuronal labeling is in human patients, the identification of unique peptide sequences that bind to human nerves was sought. The peptide sequences described in this application were identified by their ability to bind to human nerves. These peptide sequences were identified by their ability to bind to human nerves after systemic intravenous injection into human patients, and therefore, these peptides are more likely to bind to human nerves compared to sequences selected for rodent nerves.

[0361] Current methods for labeling neurons include the application of fluorescent tracer dyes (Fast Blue, Rhodamine-isothiocyanate, Fluoro-Ruby, Fluoro-Emerald), carbocyanine dyes (DiI, DiAsp, DiO, DiA), Fluoro-Gold, fluorescently labeled latex beads, fluorescently labeled plant lectins and bacterial toxins (wheat germ agglutinin, peanut agglutinin, concanavalin A, Phaseolus vulgaris leukoagglutinin (PHA-L), soybean agglutinin, gorse agglutinin, castor bean agglutinin (I and II), tetanus toxin fragment C, cholera toxin B, and fluorescently labeled dextran conjugates.

[0362] method: Experimental Details: To identify peptides that bind to human neural tissue, we used an m13 phage library (Creative Biolabs) expressing random 16-amino acid sequences at the N-terminus of gIII or an in-house generated library expressing derivatives of NP41.

[0363] Peptide selection Human peripheral nerves were obtained from patients undergoing neurectomy and homogenized. The phage library mixture was incubated with the nerve homogenate bound to a high-protein-binding 6-well plate. After incubation, the mixture was centrifuged and the pellet was either washed with PBS or the plate was washed with PBS. The pellet was either rehomogenized and plated for titering and reamplification or released from the plate with a low pH buffer. Bound phage were sequenced at each round, and repeats were recorded. No repeats were identified until round 4 of selection. SGQVPWEEPYYVVKKSS (HNP401; SEQ ID NO: 1), WEYHYVDLNWTSQHPQ (HNP402; SEQ ID NO: 2), DLPDIIWDFNWETA (HNP403; SEQ ID NO: 3) and DTHAHAKPRVPAFKSV (SEQ ID NO: 16) from the X16 library were identified after round 5. Table 1. [Table 1]

[0364] In vivo testing of peptides Mice were intravenously injected with either 150 nmol or 450 nmol of fluorescein-labeled synthetic peptide. After a 2-hour wait period to allow for washout of nonspecific binding, mice were anesthetized, and a skin incision was made over the dorsal hind limb to expose the sciatic nerve. Brightfield and fluorescent images were obtained under a dissecting microscope using Metamorph software (Figure 1). Quantification of fluorescence in nerves and adjacent non-neural tissues was performed with Image J (Figure 2). Peptides were also applied topically to human nerve sections. Nerves were fresh-frozen at 0°C before sectioning. Peptides were applied topically at a concentration of 300 μM, and images of HNP401, HNP402, HNP404, and the previously reported nerve-binding peptide NP41 are shown (Figure 3). Images of variants HNP301 (SEFPRSWDMETN) (SEQ ID NO: 130) and NP124 are also shown. NP713 was also tested, but has not been reported in publications. NP713 is a derivative of NP41 with the sequence NTHPHTTSRVPSQIAR (SEQ ID NO: 131), which was enriched after seven rounds of selection on mouse tissues and was also found after four rounds of selection on human tissues. NP713 phage binding demonstrated a 4.8-fold higher nerve:muscle ratio compared to wild-type phage. FAM-NP713 demonstrated similar nerve:muscle contrast to NP41 (data not shown). All D-amino acid controls of NP-41 and NP713, as well as carboxyfluorescein not conjugated to a peptide, are also shown. HNP401 demonstrated the highest nerve-specific contrast, with the majority of labeling occurring in the perineurium. To further demonstrate the selective binding of HNP401, HNP401, NP41, and HNP404 were tested at a lower concentration of 100 μM (Figure 4). HNP401 was then tested in vivo for labeling of rat sciatic nerve and rat prostate cavernous nerve. Figure 5 shows in vivo labeling of the rat sciatic nerve. Figures 6 and 7 show in vivo labeling of the rat prostatic cavernous nerve compared to white light visualization.

[0365] Neurohoming peptide sequences identified for laboratory studies by their ability to bind to mouse nerves have been previously described. Because the peptide sequences described herein are identified by their ability to bind to human nerves after systemic intravenous injection into human patients, these peptides are even more likely to bind to human nerves compared to sequences selected for rodent nerves.

[0366] Fluorescently labeled human nerve-binding peptides are applied systemically via intravenous injection. After a short waiting period for washout of nonspecific binding, peripheral nerves can be visualized within the surgical field with appropriate excitation and emission filters.

[0367] Human nerve-binding peptides can also be conjugated to factors that may have neurotrophic or neuroprotective properties. After systemic application by intravenous injection, peptide-trophic / neuroprotective factor conjugates can promote repair / regeneration of injured nerves both peripherally and in the spinal cord.

[0368] Human nerve-binding peptides conjugated to neuroprotective / neurotrophic factors may also be conjugated to damage-homing peptides to further improve the local delivery of these factors to injured nerves and potentially promote injury resistance / repair / regeneration.

[0369] Uses and applications: Fluorescently labeled nerve-binding peptides can be used to assist surgeons in visualizing nerves during surgical procedures before physically encountering and potentially damaging them. This is particularly important during prostate surgery, because the cavernous nerves that control erections in men run very close to the prostate but are usually virtually invisible.

[0370] Nerve-binding peptide-neurotrophic / neuroprotective factor conjugates can be used to promote repair / regeneration of damaged nerves.

[0371] Nerve-binding peptides can be conjugated to photosensitizing dyes for potential use in light-induced nerve killing as a treatment for local pain. References 1.

[0373] result Nerve identification and preservation is essential in head and neck surgery. Identification of peripheral nerves is important for their preservation during surgery, as accidental cutting or injury can result in significant patient morbidity, including chronic pain, numbness, or permanent paralysis. 1 Nerve identification is particularly important during head and neck surgery. For example, facial nerve dysfunction has been reported to be 40% during the acute postoperative period and 30% one month after parotidectomy. 2、3Similarly, facial nerve dysfunction has been reported to reach 30% one year after vestibular schwannoma surgery. 4 Temporary and permanent vocal cord immobility is a major surgical complication of thyroid surgery, anterior cervical approach to the spine, esophagectomy, and carotid endarterectomy. 5 Although the course of the facial nerve typically follows defined anatomical landmarks, extensive interpatient variability has been documented for each branch of the extratemporal facial nerve, including variability in the total number of divisions, the origin of individual divisions, and the connections between divisions. 6-9 Even within the same patient, the left and right facial nerves may show differences in course and division. 10 Similar variability has been documented for the recurrent laryngeal nerve. 11、12 In the case of tumor invasion, inflammation, trauma, or reoperation, nerve identification can become even more difficult. Finally, the identification of degenerating nerves, which is crucial during reconstructive surgery, is even more difficult than their functioning counterparts because they become smaller and thinner with time. Consequently, any means of improving the visual determination between neural and non-neural tissue represents a significant advance in surgical technique.

[0374] Nerve identification and preservation is essential during other surgeries, including prostate cancer surgery. Prostate cancer is the most common solid organ malignancy in American men. For men with localized prostate cancer, surgery provides excellent cancer control. Often, this cancer treatment comes at the expense of erectile function, urinary control, and overall quality of life. Preservation of the autonomic neurovascular bundle during radical prostatectomy is a critical aspect of surgery. For nearly 20 years, the importance of preserving the autonomic nerves that run along the posterolateral aspect of the prostate to preserve erectile function has been recognized. However, the autonomic nerve fibers themselves are rarely visualized. Instead, surgeons preserve the vascular complex or neurovascular bundle, which has been shown to have the highest density of autonomic nerves. Erectile dysfunction and urinary incontinence are common, even among the most experienced surgeons. 14 As such, the exact location and distribution of these autonomic nerves varies. 13-18Improved sexual function outcomes are associated with increased surgeon experience and avoidance of crush or traction injuries to these nerves. Significant anatomical variability and differences in surgeon experience and volume create opportunities for improving surgical quality while minimizing adverse outcomes. In cases of tumor infiltration, inflammation, trauma, or reoperation, nerve identification and preservation represent additional challenges. Finally, tactile feedback 19 The increasing use of robotic-assisted surgery, with its inherent lack of visual information, further increases the surgeon's reliance on visual information. Consequently, any means of improving visual decision-making between neural and non-neural tissue represents a significant advancement.

[0375] Small nerves are difficult to identify intraoperatively. Thin or buried nerves are particularly difficult to distinguish and are therefore most likely to be damaged during surgical procedures. Identification of motor nerves before direct exposure is currently achieved through electromyography (EMG) monitoring, in which stimulating electrodes are inserted and distal muscle contractions are monitored. 20-22 EMG is not an imaging technique, so even if a nerve is identified at one location, there is no visual guide as to how far and in what direction it lies from the stimulation site. Furthermore, EMG only identifies motor pathways, not sensory fibers such as the first two divisions of the trigeminal or cochleovestibular nerves, nor sympathetic pathways such as the neurovascular bundles around the prostate. 23-25 Nerve damage after radical prostatectomy leads to significant urinary incontinence and erectile dysfunction 26 Electrode insertion itself can damage nerves. Finally, EMG fails when axonal or neuromuscular transmission is temporarily blocked at a location distant from the recording site by nerve compression, trauma, tumor infiltration, local anesthetics, or neuromuscular blocking agents. Optical coherence tomography 27 or laser confocal microscopy 28There are several potential techniques for in vivo nerve visualization without exogenous probe molecules, such as MRI, MRI, and MRI. However, nerves have very little intrinsic contrast to distinguish them from other tissues, and these techniques do not easily generate real-time live images across the field of view necessary to guide surgery. Degenerated nerves, which are important to identify during reconstructive surgery after cancer resection, traumatic, or therapeutic amputation, also lack myelin and therefore do not benefit from these agents.

[0376] Competing strategies for improving intraoperative nerve visualization. For these reasons, there is great interest in developing labeling reagents that improve intraoperative neurovisualization. 29-32 or the B subunit of cholera toxin (CTb488) 33 Nerve labeling, which relies on retrograde or anterograde tracing of individual axon tracts through the use of fluorescent dyes, has gained considerable attention. Fluorescent dyes are applied to innervation targets and travel in a retrograde manner to label innervating nerve fibers, or they are applied directly to identified nerves, labeling nerve fibers both anterogradely and retrogradely. Local injections have the disadvantage of only being able to label a single nerve fiber tract at a time. Anterograde and retrograde transport are relatively slow and can take days to travel several millimeters, leaving most of the tracer at the injection site. Because nerve dissection relies on accurate visualization of adjacent structures, a surgical site heavily contaminated with excess fluorescent dye is undesirable. Finally, direct injection of fluorescent dyes can damage the target organ or nerve of interest, either through mechanical injury or very high local concentrations of dye and vehicle at the injection site.

[0377] More recently, there has been interest in labeling the vascular supply of nerves (i.e., the vasa nervorum) using vascular dyes such as indocyanine green (ICG). 34、35 One limitation of this technique is that small nerves (such as the cavernous nerves important for prostate surgery) have proportionally fewer neurovasculature, limiting contrast and intensity compared to adjacent tissue.

[0378] Distyrylbenzene (DSB) derivatives 36, coumarin derivatives and anti-ganglioside antibodies 37 Myelin-targeting agents have also been attracting attention, including DSB and coumarin derivatives, which are small molecules with inherent fluorescence, and anti-ganglioside antibodies, which can be conjugated to fluorescent dyes for imaging. 36-43 While these molecules are potentially promising for peripheral nerve imaging, unmyelinated nerves (autonomic and minimally myelinated), such as cavernous nerves, have little binding, which may limit their usefulness in these important procedures. Degenerating nerves have limited myelin present and therefore are not labeled by these agents.

[0379] The method of systemic injection of fluorescently labeled peptides to label nerves described herein addresses all of the disadvantages of other nerve targeting techniques mentioned above.
