DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] The present inventors have identified compounds, in particular small molecule radioconjugates (SMRCs), that bind to fibroblast activation proteins (FAPs) and are suitable for targeting applications.

[0019] The compounds according to the invention form stable complexes with FAPs and exhibit increased affinity, increased inhibitory activity, slower rate of dissociation from the complex, and / or prolonged residence at the disease site. The compounds according to the invention may further have increased tumor-to-liver, tumor-to-kidney, and / or tumor-to-intestine uptake ratios; more potent antitumor efficacy (e.g., measured by mean tumor volume increase), and / or lower toxicity (e.g., as determined by evaluation of % change in body weight). The compounds according to the invention preferably achieve FAP-specific cell binding; FAP-selective accumulation on cell membranes; FAP-selective accumulation inside the cytosol. Furthermore, the compounds according to the invention may preferably be rapidly and homogeneously localized to tumor sites in vivo with high tumor-to-organ selectivity, especially for melanoma and / or renal cell carcinoma.

[0172] The compounds described herein may be in the form of pharmaceutical compositions that may be for human or animal use in human and veterinary medicine, typically comprising any one or more of pharmaceutically acceptable diluents, carriers or excipients.Acceptable carriers or diluents for therapeutic use are well known in the pharmaceutical arts and are described, for example, in Remington's Pharmaceutical Sciences, Mack Publishing Co. (A.R. Gennaro, ed. 1985). The choice of pharmaceutical carrier, excipient or diluent can be selected with respect to the intended route of administration and standard pharmaceutical practice. Pharmaceutical compositions can comprise, as - or in addition to - carriers, excipients or diluents, any suitable binders, lubricants, suspending agents, coating agents, solubilizers.
[0173] Preservatives, stabilizers, dyes and even flavorings can be provided in the pharmaceutical composition.Examples of preservatives include sodium benzoate, sorbic acid and esters of p-hydroxybenzoic acid.Antioxidants and suspending agents can also be used.
[0174] There are different composition / formulation requirements depending on different delivery systems.For example, pharmaceutical compositions can be formulated to be administered using mini-pumps, or can be formulated to be administered by mucosal routes, for example as nasal sprays or aerosols for inhalation or orally ingestible solutions, or can be formulated to be administered parenterally, where the compositions are formulated in injectable form for delivery by intravenous, intramuscular or subcutaneous routes.Alternatively, formulations can be designed to be administered by multiple routes.
[0175] If the agent is administered mucosally, via the gastrointestinal mucosa, it should be able to remain stable during transit through the gastrointestinal tract; for example, it should be resistant to proteolysis, stable at acid pH, and resistant to the detergent effects of bile.
[0176] Where appropriate, the pharmaceutical composition can be administered by inhalation, in the form of a suppository or pessary, topically in the form of a lotion, solution, cream, ointment or dusting powder, by using a skin patch, in the form of a tablet containing excipients such as starch or lactose, or in capsules or ovules, either alone or in admixture with excipients, or in the form of an elixir, solution or suspension containing flavoring or coloring agents, or the pharmaceutical composition can be injected parenterally, for example, intravenously, intramuscularly or subcutaneously.For parenteral administration, the composition can be best used in the form of a sterile aqueous solution, which can contain other substances, for example, sufficient salts or monosaccharides, to make the solution isotonic with blood.For buccal or sublingual administration, the composition can be administered in the form of a tablet or lozenge, which can be formulated in a conventional manner.
[0177] The compound of the present invention can be administered in the form of pharmaceutically acceptable salt or active salt.Pharmaceutically acceptable salt is well known to those skilled in the art, and includes, for example, those described by Berge et al. in J.Pharm.Sci., 66, 1-19 (1977). Salts include, but are not limited to, sulfate, citrate, acetate, oxalate, chloride, bromide, iodide, nitrate, bisulfate, phosphate, acid phosphate, isonicotinate, lactate, salicylate, acid citrate, tartrate, oleate, tannate, pantothenate, bitartrate, ascorbate, succinate, maleate, gentisate, fumarate, gluconate, glucarate, saccharate, formate, benzoate, glutamate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, and pamoate (i.e., 1,1'-methylene-bis-(2-hydroxy-3-naphthoate)) salts.
[0178] Routes for administration (delivery) can include, but are not limited to, one or more of oral (e.g., as a tablet, capsule, or as an orally ingestible solution), topical, mucosal (e.g., as a nasal spray or aerosol for inhalation), nasal, parenteral (e.g., via an injectable form), gastrointestinal, intrathecal, intraperitoneal, intramuscular, intravenous, intrauterine, intraocular, intradermal, intracranial, intratracheal, intravaginal, intraventricular, intracerebral, subcutaneous, ophthalmic (including intravitreal or intracameral), transdermal, rectal, buccal, intravaginal, epidural, and sublingual.
[0179] Typically, a physician will determine the actual dosage that will be most appropriate for an individual subject. The specific dose level and frequency of administration for any particular patient can vary and will depend on a variety of factors, including the activity of the particular compound employed, the metabolic stability and length of action of that compound, age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the individual being treated.
[0180] The formulations can be packaged in unit-dose or multi-dose containers, such as sealed ampoules and vials, and can be stored in a freeze-dried (lyophilized) state, requiring only the addition of a sterile liquid carrier, such as water, for administration. Extemporaneous injection solutions and suspensions are prepared from sterile powders, granules and tablets of the type previously described. Illustrative unit dosage formulations contain a daily dose or a unit sub-dose of the active ingredient, or an appropriate fraction thereof. chemical synthesis The compounds described herein can be prepared by chemical synthesis techniques.
[0181] It will be apparent to those skilled in the art that sensitive functional groups may need to be protected and deprotected during the synthesis of the compounds. This can be accomplished by conventional techniques, for example as described in "Protective Groups in Organic Synthesis" by TW Greene and PGM Wuts, John Wiley and Sons Inc. (1991), and in "Protecting Groups" by PJ Kocienski, Georg Thieme Verlag (1994).
[0182] It is possible that in some reactions any stereocenters present may be epimerized under certain conditions, for example if a base is used in the reaction with a substrate having an optical center containing a base-sensitive group. As is well known in the art, it should be possible to avoid such potential problems by choice of reaction sequence, conditions, reagents, protection / deprotection regimes, etc. definition Derivatives. Derivatives include chemical modifications of compounds. Examples of such modifications include replacement of hydrogen with halo, alkyl, acyl or amino groups, etc. Modifications can increase or decrease one or more hydrogen bonding interactions, charge interactions, hydrophobic interactions, van der Waals interactions and / or dipole interactions.

The term includes reference to groups such as phenyl, naphthyl, fluorenyl, azulenyl, indenyl, anthryl, and the like.
[0189] The prefix "hetero" means that one or more of the carbon atoms of the group may be replaced by nitrogen, oxygen, phosphorus, silicon or sulfur, unless otherwise specified. Heteroalkyl groups include, for example, alkyloxy and alkylthio groups. A heterocycloalkyl or heteroaryl group herein can have 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16 ring atoms, at least one of which is selected from nitrogen, oxygen, phosphorus, silicon and sulfur. In particular, the 3- to 10-membered ring or ring system, and more particularly the 5- or 6-membered ring, can be saturated or unsaturated.

[0190] "Substituted" means that, unless otherwise specified, one or more, particularly up to 5, more particularly 1, 2 or 3 of the hydrogen atoms in said moiety are replaced independently of one another by a corresponding number of substituents. The term "optionally substituted" as used herein includes being substituted or unsubstituted. Of course, it is understood that the substituents are only in positions where they are chemically possible, and the skilled person can determine (either experimentally or theoretically) without undue effort whether a particular substitution is possible. For example, an amino group or a hydroxy group having a free hydrogen may be unstable if it is bound to a carbon atom with an unsaturated (e.g., olefinic) bond. Preferably, the term "substituted" means that one or more, particularly up to 5, more particularly 1, 2 or 3 of the hydrogen atoms in said moiety are replaced independently of one another by a corresponding number of substituents selected from OH, SH, NH2, halogen, cyano, carboxy, alkyl, cycloalkyl, aryl and heteroaryl. Additionally, the substituents described herein may themselves be substituted with any substituent, subject to the aforementioned limitations on suitable substitution recognized by those of skill in the art. Preferably, any of the aforementioned substituents may be further substituted with any of the aforementioned substituents, each of which may be further substituted with any of the aforementioned substituents.
[0191] The substituents may suitably include halogen atoms and halomethyl groups, such as CF3 and CCl3; oxygen-containing groups, such as oxo, hydroxy, carboxy, carboxyalkyl, alkoxy, alkoyl, alkoyloxy, aryloxy, aryloyl and aryloyloxy; nitrogen-containing groups, such as amino, alkylamino, dialkylamino, cyano, azide and nitro; sulfur-containing groups, such as thiol, alkylthiol, sulfonyl and sulfoxide; heterocyclic groups, which may themselves be substituted; alkyl groups, which may themselves be substituted; and aryl groups, such as phenyl and substituted phenyl, which may themselves be substituted. Alkyl includes substituted and unsubstituted benzyl.
[0192] More preferably, "substituted" is selected from the group consisting of OH, SH, NH, halogen, cyano, oxo, carboxy, C(O)NHC 1~6 Alkyl, C 1~6 Alkoxy, C(O)C 1~6 Alkyl, C 1~6 Alkylthio, C 1~5 Heteroalkyl, C 1~5 Heteroalkoxy, C 3~6 Cycloalkyl, C 3~6 Cycloalkoxy, C 6~10 Aryl, C 6~10 Aryloxy, C 5~10 Heteroaryl and C 5~10 Heteroaryloxy means substitution with one or more groups selected from the group consisting of SH, NH2, C(O)NH2, C 1~6 Alkyl, C 1~6 Alkoxy, C(O)C 1~6 Alkyl, C 1~6 Alkylthio, C 1~5 Heteroalkyl, C 1~5 Heteroalkoxy, C 3~6 Cycloalkyl, C 3~6 Cycloalkoxy, C 6~10 Aryl, C 6~10 Aryloxy, C 5~10 Heteroaryl and C 5~10Heteroaryloxy is OH, SH, NH2, halogen, cyano, oxo, carboxy, C 1~6 Alkyl, C 1~5 Heteroalkyl, C 3~6 Cycloalkyl, C 6~10 Aryl and C 5~10 and optionally substituted with one or more of the heteroaryl; two or more of the previously mentioned groups can be joined together to form a carbocyclic or heterocyclic ring system moiety.
[0193] When two or more moieties are described as being "each independently" selected from a list of atoms or groups, this means that the moieties can be the same or different, and the identity of each moiety is therefore independent of the identity of the other moiety or moieties. EXAMPLES
