AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant (s) SOCIETE DE CONSEILS DE RECHERCHES ET D'APPLICATIONS SCIENTIFIQUES, S.A.S. Invention Title: ELICITING A DOPAMONE RECEPTOR AGONIST EFFECT WITH SOMATOSTATIN-DOPAMINE CHIMERIC ANALOGS The following statement is a full description of this invention, including the best method for performing it known to me/us: ELICITING A DOPAMINE RECEPTOR AGONIST EFFECT WITH SOMATOSTATIN-DOPAMINE CHIMERIC ANALOGS Background of the Invention 5 [001] The present invention is drawn to somatostatin-dopamine chimeric analogs and methods relating to their therapeutic use. 10021 Dopamine is a catecholamine neurotransmitter that has been implicated in the pathogenesis of both Parkinson disease and schizophrenia. Dopamine and related molecules have been shown to inhibit the growth of several types of malignant tumors 10 in mice, and this activity has been variously attributed to inhibition of tumor-cell proliferation, stimulation of tumor immunity or as well as effects on melanin metabolism in malignant melanomas. Recent studies demonstrated the presence of D2 dopamine receptors on endothelial cells. Dopamine has recently been reported to strongly and selectively inhibit at non-toxic levels the vascular permeabilizing and 15 angiogenic activities of VPF/VEGF. 10031 Somatostatin (SS), a tetradecapeptide has been shown to have potent inhibitory effects on various secretory processes in tissues such as pituitary, pancreas and gastrointestinal tract. SS also acts as a neuromodulator in the central nervous system. These biological effects of SS, all inhibitory in nature, are elicited through a 20 series of G protein coupled receptors, of which five different subtypes have been characterized (SSTR-1 - SSTR-5). These five subtypes have similar affinities for endogenous SS ligands, but have differing distributions in various tissues. Somatostatin binds to the five distinct receptor (SSTR) subtypes with relatively high and equal affinity for each subtype. 25 [0041 There is evidence that SS regulates cell proliferation by arresting cell growth via SSTR-1, -2, -3, -4, and -5 subtypes, and/or by inducing apoptosis via SSTR-3 subtype. SS and various analogues have been shown to inhibit normal and neoplastic cell proliferation in vitro and in vivo via specific SS receptors (SSTR's) and possibly different postreceptor actions. In addition, there is evidence that distinct SSTR subtypes 30 are expressed in normal and neoplastic human tissues, conferring different tissue affinities for various SS analogues and variable clinical response to their therapeutic effects. H:\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 2 [0051 Binding to different types of somatostatin receptor subtypes is associated with the treatment of various conditions and/or diseases. For example, the inhibition of growth hormone has been attributed to the somatostatin type-2 receptor ("SSTR-2"), while the inhibition of insulin has been attributed to the somatostatin type-5 receptor 5 ("SSTR-5"). Activation of types 2 and 5 have been associated with growth hormone suppression and more particularly growth hormone secreting adenomas (acromegaly) and thyroid stimulating hormone (TSH) secreting adenomas. Activation of type 5 but not type 2 receptor has been associated with treating prolactin secreting adenomas. Other indications associated with activation of the somatostatin receptor subtypes 10 include inhibition of insulin and/or glucagon for treating diabetes mellitus, angiopathy, proliferative retinopathy, dawn phenomenon, and nephropathy; inhibition of gastric acid secretion for treating peptic ulcers, enterocutaneous and pancreaticocutaneous fistula, irritable bowel syndrome, Dumping syndrome, watery diarrhea syndrome, AIDS related diarrhea, chemotherapy-induced diarrhea, acute or chronic pancreatitis and 15 gastrointestinal hormone secreting tumors; treatment of cancer such as hepatoma; inhibition of angiogenesis; treatment of inflammatory disorders such as arthritis; retinopathy; chronic allograft rejection; angioplasty; preventing graft vessel and gastrointestinal bleeding. Preferably, a somatostatin analog is selective for the specific somatostatin receptor subtype or subtypes responsible for the desired biological 20 response to reducing interaction with other receptor subtypes which could lead to undesirable side effects or loss of efficacy. [0061 Somatostatin and its receptors (SSTR-1 to SSTR-5) are expressed in normal human parafollicular C cells and medullary thyroid carcinoma (MTC). MTC is a tumor originating from thyroid parafollicular C cells that produces calcitonin (CT), 25 somatostatin, and several other peptides. It was recently demonstrated that SS and SSTR's are expressed in human MTC, and SS and SS analogues were shown to induce a decrease in plasma CT levels and provide symptomatic improvement in MTC patients. Another recent study has shown that SS and SS analogs, in particular, SSTR- 1 and SSTR-2, can inhibit the proliferation of tumor cells, suggesting that specific SSTR 30 subtypes can function in MTC cell growth regulation. The development and characterization of SSTR subtype analogues that selectively effect MTC cell growth is useful for clinical and therapeutic applications. H:\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 3 Summary of the Invention 10071 The present invention is based on our discovery of somatostatin-dopamine chimeric analogs, comprising compounds that retain both somatostatin and dopamine 5 activity. The chimeric analogs of the invention are considered to be useful, e.g., in vitro, for use as research tools, diagnostic assays, etc., or in vivo, for use as diagnostic or therapeutic agents. Preferred chimeric analogs of the invention display enhanced activity when compared to native somatostatin and dopamine, either alone or in combination. 10 10081 Accordingly, in a first aspect, the invention features a chimeric analog comprising (1) at least one moiety which binds to one or more somatostatin receptor(s) and (2) at least one moiety which binds to one or more dopamine receptor(s), or a pharmaceutically acceptable salt thereof. 10091 In a first embodiment of the first aspect, the chimeric analog comprises 15 formula (I), Y- (L)m Z (W)" N.-R1 R3 H R2" 20 x N R4 (I) wherein: 25 100101 X is H, Cl, Br, I, F, -CN, C 1

Synthesis of Somatostatin Agonists 102841 The methods for synthesizing peptide somatostatin agonists are well 15 documented and are within the ability of a person of ordinary skill in the art. For example, peptides are synthesized on Rink amide MBHA resin (4-(2'4' dimethoxyphenyl-Fmoc-aminomethyl)-phenoxyacetamido-norleucyl-MBHA resin) using a standard solid phase protocol of Fmoc chemistry. The peptide-resin with free amino functional at the N-terminus is then treated with the corresponding compound 20 containing dopamine moiety. The final product is cleaved off from resin with TFA water/triisopropylsilane (TIS) mixture. [02851 For example, synthesis of H-D-Phe-Phe-Phe-D-Trp-Lys-Thr-Phe-Thr-NH 2 , can be achieved by following the protocol set forth in Example I of European Patent Application 0 395 417 Al. The synthesis of somatostatin agonists with a substituted N 25 terminus can be achieved, for example, by following the protocol set forth in PCT Publication No. WO 88/02756, PCT Publication No., WO 94/04752, and/or European Patent Application No. 0 329 295. [02861 Peptides can be and were cyclized by using iodine solution in MeOH/water and purified on C18 reverse-phase preparative HPLC, using acetonitrile 30 0.1 %TFA/water-0. I %TFA buffers. Homogeneity was assessed by analytical HPLC and mass spectrometry and determined to be >95% for each peptide.

Endocrin. and Metab. 87:5545-5552, 2002), hereby incorporated by reference. 15 [02911 The following examples are provided to illustrate the invention. They are not meant to limit the invention in any way. Example 1: Dop2-DLys(Dop2)-DPhe-cyclo[Cys-3ITyr-DTrp-Lys-Thr-Cys]-Thr-NH 2 102921 The Dop2-DLys(Dop2)-DPhe-cyclo[Cys-3ITyr-DTrp-Lys-Thr-Cys]-Thr 20 NH 2 peptide was automatically synthesized on an ACT 396 peptide synthesizer (Advanced ChemTech, Louisville, KY) using Fluorenylmethyloxycarbonyl (Fmoc) chemistry. A RINK AMIDE 4-methylbenzylhydrylamine (MBHA) resin (Novabiochem., San Diego, CA) with substitution of 0.66 mmol/g was used (sub: 0.66 mmol/g, 76 mg, 50 imol scale). The Fmoc amino acids used are Fmoc-DTrp(Boc)-OH, 25 Fmoc-Lys(Boc)-OH, Fmoc-Thr(But)-OH, Fmoc-DPhe-OH, Fmoc-Cys(Trt)-OH, and Fmoc-DLys(Dde))-OH from NOVABIOCHEM (San Diego, CA) and Fmoc-31Tyr-OH from CHEM-IMPEX INTERNATIONAL, Inc. (Wood Dale, IL). The synthesis was carried out on a 50 imol scale. For each reaction cycle, the ACT 396 peptide synthesizer was programmed to perform: (1) washing with N-methylpyrrolidone (NMP) 30 twice; (2) removing Fmoc protecting group with 20% piperidine in NMP for 1 X 5 min and I X 25 min; (3) washing with NMP twice; and (4) double coupling with 4 X fold excess of Fmoc protected amino acid (0.20 mmol), HOBt (0.2 mmol), and N, N' H:\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 57 diisopropylcarbodiimide (DIC) (0.2 mmol) in NN-dimethylformamide (DMF) for I hour per coupling. The resin was coupled successively according to the sequence. 102931 After the peptide chain was assembled, the Fmoc group was removed and the resin was washed completely using NMP and dichloromethane (DCM). The resin was 5 transferred into a reaction vessel on a shaker and treated with 2% hydrozine in DMF for 2 X 30 minutes to remove Dde protecting group in the side chain of DLys. After washing successively with DMF, MeOH and DCM, the resin was shaken overnight with Dop2-OH (54 mg, 3.0 eq), bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (PyBrop, 82 mg, 3.4 eq), 1-hydroxy-7-azabenzotriazole (HOAT, 0.4 mg, 3.0 eq), 10 pentalflurophenol (18.4 mg, 4 eq), DMAP (0.25 mL of 0.1 M in DMF, 1.0 eq) and diisopropylethyl amine (DIEA) (53 pL, 4 eq). [02941 After washing successively with DMF, MeOH and DCM, the resin was treated with a mixture of TFA (4.75 mL), H 2 0 (0.4 mL), and triisopropylsilane (TIS, 0.425 mL) for 2 hours. The resin was removed by filtration. The filtrate was poured 15 into 70 mL of ether. The precipitate formed was filtered off and washed thoroughly with ether. This crude product was dissolved in 5 mL of aqueous acetic acid solution (water/acetic acid = 1:1). The solution was then diluted with 50 mL of H 2 0 and 20 mL of acetonitrile, to which was added, dropwise, iodine in methanol until the solution acquired a sustained yellow hue. The solution was stirred slowly for 1 hour and the 20 reaction was terminated by adding aqueous Na 2

S

2 0 3 solution. The crude product was purified on reverse-phase preparative HPLC using a column of C18 DYNAMAX 100A 0 (4 x 43 cm, Varian, Walnut Creek, CA). The column was eluted with a liner gradient from 90% A and 10% B to 60% A and 40% B in an hour where A was 0.1% TFA in water and B was 0.1% TFA in acetonitrile. Fractions containing a major 25 component by ultraviolet (UV) absorption were pooled and lyophilized. The purity was 95.7% based on an analytical HPLC analysis. Electro-spray ionization mass spectrometry (ESI mass) analysis gave the molecular weight at 1982.6 (in agreement with the calculated molecular weight of 1983.3). 30 Example 2: Dop2-DPhe-Doc-DPhe-cyclo[Cys-3ITyr(Dop2)-DTrp-Lys-Val-Cys]-Thr

After the 5 assembly of the peptide chain, the resin was transferred into a reaction vessel on a shaker and treated with 25% piperidine in DMF for 30 minutes to remove the Fmoc protecting group at the N-terminus. After washing successively with DMF, MeOH and DCM, the resin was shaken overnight with Dop2-OH (3.0 eq), PyBrop (3.4 eq), HOAT (3.0 eq), DMAP (1.0 eq) and DIEA (4 eq). After cleavage and purification, the desired 10 product was found to have a purity of 95% based on an analytical HPLC analysis. ESI mass analysis gave the molecular weight at 2145.9 (in agreement with the calculated molecular weight of 2145.6).

Additional asymmetric centers may be present in the molecule depending upon 20 the nature of the various substituents of the molecule. Each such asymmetric center will produce two optical isomers and it is intended that all such optical isomers, as separated, pure or partially purified optical isomers, racemic mixtures or diastereomeric mixtures thereof, are included within the scope of the instant invention. [03271 The compounds of the instant invention generally can be provided in the 25 form of their pharmaceutically acceptable acid addition salts, such as the salts derived from using inorganic and organic acids. Examples of such acids are hydrochloric, nitric, sulfuric, phosphoric, formic, acetic, trifluoroacetic, propionic, maleic, succinic, D-tartaric, L-tartaric, malonic, methane sulfonic and the like. In addition, certain compounds containing an acidic function such as a carboxy can be isolated in the form 30 of their inorganic salt in which the counter-ion can be selected from sodium, potassium, lithium, calcium, magnesium and the like, as well as from organic bases. H.\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 87 [03281 The pharmaceutically acceptable salts can be formed by taking about I equivalent of a compound of the invention and contacting it with about I equivalent or more of the appropriate corresponding acid of the salt which is desired. Work-up and isolation of the resulting salt is well-known to those of ordinary skill in the art. 5 103291 The compounds of this invention can be administered by oral, parenteral (e.g., intramuscular, intraperitoneal, intravenous or subcutaneous injection, or implant), nasal, vaginal, rectal, sublingual or topical routes of administration and can be formulated with pharmaceutically acceptable carriers to provide dosage forms appropriate for each route of administration. Accordingly, the present invention 10 features pharmaceutical compositions comprising, as an active ingredient, at least one compound of the invention in association with a pharmaceutically acceptable carrier. 103301 Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the active compound is admixed with at least one inert pharmaceutically acceptable carrier such as sucrose, lactose, or 15 starch. Such dosage forms can also comprise, as is normal practice, additional substances other than such inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings. 103311 Liquid dosage forms for oral administration include pharmaceutically 20 acceptable emulsions, solutions, suspensions, syrups, the elixirs containing inert diluents commonly used in the art, such as water. Besides such inert diluents, compositions can also include adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring and perfuming agents. [03321 Preparations according to this invention for parenteral administration include 25 sterile aqueous or non-aqueous solutions, suspensions, or emulsions. Examples of non aqueous solvents or vehicles are propylene glycol, polyethylene glycol, vegetable oils, such as olive oil and corn oil, gelatin, and injectable organic esters such as ethyl oleate. Such dosage forms may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. They may be sterilized by, for example, filtration through a 30 bacteria-retaining filter, by incorporating sterilizing agents into the compositions, by irradiating the compositions, or by heating the compositions. They can also be H-\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 88 manufactured in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. [03331 Compositions for rectal or vaginal administration are preferably suppositories which may contain, in addition to the active substance, excipients such as coca butter or 5 a suppository wax. [0334] Compositions for nasal or sublingual administration are also prepared with standard excipients well known in the art. 10335] In general, an effective dose of an active ingredient in the compositions of this invention may be varied; however, it is necessary that the amount of the active 10 ingredient be such that a suitable dosage form is obtained. The selected dosage depends upon the desired therapeutic effect, on the route of administration, and on the duration of the treatment, all of which are within the realm of knowledge of one of ordinary skill in the art. Generally, dosage levels of between 0.0001 to 100 mg/kg of body weight daily are administered to humans and other animals, e.g., mammals. 15 103361 Preferred dosage ranges are from 0.01 to 10.0 mg/kg of body weight. Such dosages may be administered, for example, daily as a single dose or divided into multiple doses. Somatostatin Receptor Specificity and Selectivity Assay 20 [03371 Specificity and selectivity of the somatostatin analogues used to synthesize the somatostatin-dopamine chimers was determined by a radioligand binding assay on CHO-KI cells stably transfected with each of the SSTR subtypes, as follows. Somatostatin analogs are also described in U.S. Patent Application Publication No. 02210006790. The complete coding sequences of genomic fragments of the SSTR 1 25 (e.g., Genbank accession No. M81829), SSTR 2 (e.g., Genbank accession No. M81830), SSTR 3 (e.g., Genbank accession No. L07062), and SSTR 4 (e.g., Genbank accession No. AL049651) genes and a cDNA clone for SSTR 5 (e.g., Genbank accession No. D16827) was subcloned into the mammalian expression vector pCMV (Life Technologies, Milano, Italy). Other SSTR sequences are known to the skilled 30 artisan. Clonal cell lines stably expressing SSTR's 1-5 were obtained by transfection into CHO-Kl cells (ATCC, Manassas, Va, USA) using the calcium phosphate co precipitation method (Davis L, et al., 1994 In: Basic methods in Molecular Biology, 2nd H:\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 89 edition, Appleton & Lange, Norwalk, CT, USA: 611-646). The plasmid pRSV-neo (ATCC) was included as a selectable marker. Clonal cell lines were selected in RPMI 1640 media containing 0.5 mg/ml of G418 (Life Technologies, Milano, Italy), ring cloned, and expanded into culture. 5 [03381 Membranes for in vitro receptor binding assays were obtained by homogenizing the CHO-KI cells expressing the SSTR's subtypes in ice-cold 50 mM Tris-HCl and centrifuging twice at 39000 g (10 min), with an intermediate resuspension in fresh buffer. The final pellets were resuspended in 10 mM Tris-HCl for assay. [03391 For the SSTR 1, 3, 4, and 5 assays, aliquots of the membrane preparations 10 were incubated 90 minutes at 25 0 C with 0.05 nM [1 2 1I-Tyrl l]SS-14 in 50 mM HEPES (pH 7.4) containing 10 mg/ml bovine serum albumin (BSA), 5 mM MgCl 2 , 200 KIU/ml Trasylol, 0.02 mg/ml bacitracin, and 0.02 mg/ml phenylmethylsuphonyl fluoride. The final assay volume was 0.3 ml. [03401 For the SSTR 2 assay, 0.05 nM [mI]MK-678 was employed as the 15 radioligand and the incubation time was 90 minutes at 25 *C. The incubations were terminated by rapid filtration through GF/C glass microfibre filters (Whatman Co.) (pre soaked in 0.3% polyethylenimine) using a BRANDEL filtration manifold. Each tube and filter was washed three times with 5 ml aliquots of ice-cold buffer. Specific binding was defined as the total radioligand bound minus that bound in the presence of 20 1000 nM SS-14 for SSTR 1, 3, 4, and 5, or 1000 nM MK-678 for SSTR2. Dopamine Receptor Specificity and Selectivity Assay [0341] Specificity and selectivity for the dopamine-2 receptor of the dopamine analogues used to synthesize the somatostatin-dopamine chimers may be determined by 25 a radioligand binding assay as follows. [03421 Crude membranes were prepared by homogenization of frozen rat corpus striatum (Zivic Laboratories, Pittsburgh, PA) in 20 ml of ice-cold 50 mM Tris-HCl with a BRINKMAN POLYTRON cell disrupter (setting 6, 15 sec). Buffer was added to obtain a final volume of 40 ml, and the homogenate was centrifuged in a SORVAL SS 30 34 rotor at 39,000 g for 10 minutes at 0-4 *C. The resulting supernatant was decanted and discarded. The pellet was rehomogenized in ice-cold buffer, pre-incubated at 37 *C H:\MaraR\Keep\Speci\P64461-div-SPEC.doc 7/02/08 - 90 for 10 min, diluted, and centrifuged as before. The final pellet was resuspended in buffer and held on ice for the receptor binding assay. 103431 For assay, aliquots of the washed membrane preparations and test compounds were incubated for 15 minutes (37 *C) with 0.25 nM [ 3 HI]spiperone (16.5 Ci.mmol, 5 New England Nuclear, Boston, MA) in 50 mM Tris HCl, 120 mM NaCl, 5 mM KCl, 2 mM CaCl 2 , 1 mM MgCl2. The final assay volume was 1.0 ml. The incubations were terminated by rapid filtration through GF/B glass fibre filters using a Brandel filtration manifold. Each tube and filter was then washed three times with 5-ml aliquots of ice cold buffer. Specific binding was defined as the total radioligand bound minus that 10 bound in the presence of 1000 nM (+) butaclamol. Inhibition of cAMP Intracellular Production [0344] The agonist activity of a somatostatin test compound is determined by the following assay. 15 103451 CHO-KI cells expressing human somatostatin (SRIF-14) subtype receptors are seeded in 24-well tissue culture plates in RPMI 1640 media with 10% fetal calf serum (FCS). [03461 Cells at 105 cells/well are washed 2 times by 0.5 ml RPMI 1640 media. Hank's balanced salt solution supplemented with 0.5mM 3-isobutyl-1-methylxanthine 20 ("IBMX"), and the cells are incubated for 30 minutes at 37*C. Cyclic AMP production is stimulated by the addition of 10 pM forskolin ("FSK") (Sigma Chemical Co., St. Louis, MO) for 30 minutes at 37*C. [03471 The agonist effect of a compound is measured by the addition of the test compound (10-0 M to 10~6 M) for five minutes prior to the addition of FSK (10 ptM). 25 The reaction is terminated by the addition of 500 ul of ice-cold absolute alcohol, and the supernatant is transferred to a 12x75 mm glass tube for cAMP determination. cAMP is measured using radioimmunoassay kit (Perkin-Elmer, Boston, MA).
