FIELD
[0002] The subject matter described herein is directed to ferroportin inhibitor compounds, methods 10 of making the compounds, their pharmaceutical compositions, and their use in the prophylaxis and/or treatment of diseases caused by a lack of hepcidin or iron metabolism disorders, particularly iron overioad States, such as thaiassemia, sickle cell disease and hemochromatosis, and also kidney injuries.
BACKGROUND
[0003] In nearly ail organisms, iron is an essential trace element. In humans, iron is a critical component for oxygen transport, oxygen uptake, cell fonctions such as mitochondrial électron transport, cognitive functions, and energy metabolism. Iron is présent in enzymes, hemoglobin and myoglobin, as well as in depots in the form of ferritin and hemosiderin. With respect to hemoglobin, approximately halfof ail iron is présent as heme iron, bound in the hemoglobin ofthe érythrocytes. The human body contains on average approximately 4 to 5 g iron. The iron requirement of a human adult is between 0.5 to 1.5 mg per day, whereas infants and women during pregnancy require 2 to 5 mg of iron per day. [0004] In a healthy human adult, the normal daily loss of iron of about I mg is usually replaced via food intake. Iron balance is primarily regulated by recycling and iron recovery from hemoglobin of aging érythrocytes and the duodenal absorption of dietary iron in the form of divalent as well as trivalent 25 iron ions.
[0005] Absorption is regulated by the organism depending on the iron requirement and the size of the iron depot. Usually, Fe(lII) compounds are dissolved in the stomach at a sufficiently acidic pFI value and thus made available for absorption. The absorption of the iron is carried out in the upper small intestine by mucosal cells. Trivalent non-heme iron is first reduced in the intestinal cell membrane to
Fe(ll) for absorption, for example by ferrie reductase (membrane-bound duodenal cytochrome b), so that
it can then be transported into the intestinal cells by means ofthe transport protein DMTl (divalent métal transporter l). In contrast, heme iron enters the enterocytes through the cell membrane without any change. In the enterocytes, iron is either stored in ferritin as depot iron, or released into the blood by the transport protein ferroportin. The divalent iron transported into the blood by ferroportin is converted 5 into trivalent iron by oxidases (ceruloplasmin, hephaestin). The trivalent iron is then transported to its destination in the organism by transferrin. (“Balancing acts: molecular control of mammalian iron metabolism, M.W. Hentze, Cell, l :17, 2004, 285-297). Hepcidin plays a central rôle in this process because it is the essential regulating factor of iron absorption. The hepcidin-ferroportin System directly régulâtes iron metabolism.
[0006] Iron uptake and storage is regulated by hepcidin. Hepcidin Antimicrobial Peptide (HAMP;
also known as LEAP-1 ; further referred to as Hepcidin) is a 25 amino acid peptide (Krause et al., FEBS Lett. 480, 147-150, 2000). Hepcidin has a hairpin structure with 8 cysteines that form 4 disulfide bridges (Jordan et al., J Biol Chem. 284, 24155-24167, 2009). The N-terminus appears to be important for the iron-regulatory fonction since délétion of the First 5 amino acids resulted in complété loss of bioactivity (Nemeth et al., Blood, 107,328-333, 2006). Hepcidin is produced in the liver and fonctions as the master iron regulatory hormone controlling intestinal iron uptake, and also régulâtes iron storage in other organs (Ganz, Hematol. Am.
Soc. Hematol. Educ. Program, 29-35, 507 2006; Hunier et al., J. Biol. Chem. 277, 37597-37603, 2002; Park et al., J. Biol. Chem. 276, 7806-7810, 2001). Hepcidin limits iron-uptake by binding to 20 the iron transport molécule ferroportin and causing its dégradation (Sebastiani et al., Front.
Pharmacol. 7, 160, 2016).
[0007] The formation of hepcidin is regulated în direct corrélation to the organism’s iron level, Le., if the organism is supplied with sufficient iron and oxygen, more hepcidin is formed; if iron and oxygen levels are low, or in case of increased erythropoiesis, less hepcidin is formed. In the small intestinal 25 mucosal cells and in the macrophages hepcidin binds with the transport protein ferroportin, which conventionally transports the phagocytotically recycled iron from the interior of the cell into the blood. [0008] Ferroportin is an iron transporter that plays a key rôle in regulating iron uptake and distribution in the body and thus in controlling iron levels in the blood. The transport protein ferroportin is a transmembrane protein consisting of 571 amino acids which is formed in the liver, spleen, kidneys, 30 heart, intestine and placenta. In particular, ferroportin is localized in the basolateral membrane of intestinal épithélial cells. Ferroportin bound in this way thus acts to export the iron into the blood. In this
case, it is most probable that ferroportin transports iron as Fe2+. If hepcidin binds to ferroportin, ferroportin is transported into the interior of the cell, where its breakdown takes place so that the release ofthe phagocytotically recycled iron from the cells is then almost completely blocked. Ifthe ferroportin is inactivated, for example by hepcidin, so that it is unable to export the iron which is stored in the mucosal cells, the stored iron is lost with the naturel shedding of cells via the stools. The absorption of iron in the intestine is therefore reduced, when ferroportin is inactivated or inhibited, for example by hepcidin.
[0009] A decrease of hepcidin results in an increase of active ferroportin, thus allowing an enhanced release of stored iron and an enhanced iron uptake, e.g., from the food, resulting in an increase in sérum iron levels, i.e., iron overload. Iron overload causes many diseases and undesired medical conditions. Iron overload can be treated by removal of the iron from the body. This treatment includes regularly scheduled phlébotomies (bloodletting). For patients unable to tolerate routine blood draws, there are chelating agents available for use. A disadvantage in the treatment of iron overload by chélation therapy is the removal ofthe chelated iron from the body when the iron overload has already occurred instead of preventing the occurrence ofthe disorder.
[0010] What is therefore needed and not effectively addressed by the art are compounds that act as ferroportin inhibitors that hâve desired efficacy and therapeutic potential. This problem as well as others stemming from iron imbalance are addressed by the subject matter described herein.

DETAILED DESCRIPTION
[0016] Described herein are ferroportin inhibitor compounds of Formula I and Formula F, methods of making the compounds, pharmaceutical compositions comprising the compounds and their use in the prophylaxis and/or treatment of diseases caused by a lack of hepcidin or iron metabolism disorders, particularly iron overload States, such as thalassemia, sickle cell disease and hemochroinatosis. Ferroportin is the iron transport protein responsible for the uptake of the released iron via the intestine and its transfer into the blood circulation, where ultimately the iron is delivered to the appropriate tissues and organs. Inactivation or inhibition of the ferroportin reduces or prevents the export of the iron, thereby reducing the absorption of iron in the intestine and ultimately the amount of iron in the body. These compounds, compositions and methods can be used for an effective therapy for the prophylaxis and treatment of iron metabolism disorders which are associated with increased iron levels. It is désirable to provide compounds, compositions and methods that exhibit few side effects, hâve very low toxicity and good bioavailability and compatibility.
[0017] Iron overload has been associated with a variety of diseases (Blanchette étal., Expert Rev. Hematol. 9, 169-186, 2016). Hereditary hemochroinatosis is the most common inherited disease in Europe and is caused by lack of, or insensitivity to, hepcidin (Powell et al., The Lancet
388, 706-716, 2016). The clinical manifestation of hemochromatosis are hepatic cirrhosis, diabètes, and skin pigmentation (Powell et al., The Lancet 388, 706-716, 2016). While this disease can be managed by phlebotomy, this approach may be cumbersome and does not treat the cause of the disease.
[0018] Iron-loading anémias such as beta-thalassemia are also associated with reduced hepcidin 25 levels (Origa et al., Haematoiogica 92, 583-588, 2007). Treatment of this disease with hepcidin mimetics may not only address the iron overload, but has also been shown to improve the ineffective erythropoiesis that occurs in this disease (Casu et al., Blood 128, 265-276, 2016). This may be of major beneflt for thalassemia patients who may be less dépendent on blood transfusions, which can contribute to the iron overload in these patients.
[0019] Myelofibrosis, myelodysplastic syndrome, and sickle cell disease are diseases that are
also characterized by ineffective erythropoiesis and that may require frequent blood transfusions (Carreau et al., Blood Rev. 30, 349-356, 2016; Temraz et al., Crit. Rev. Oncol. Hematol. 91,64-73, 2014; Walter étal., Acta Haematol. 122, 174-183, 2009). Reduced hepcidin levels hâve been described in some of these patients (Cui et al., Leuk. Res. 38, 545-550, 2014; Santini et al., PLoS
ONE 6, e23109, 2011). Hepcidin mimetics may also be bénéficiai in these patients.
[0020] Polycythemia vera is a disease characterized by increased erythropoiesis. It has been shown in animal models that high doses of hepcidin mimetics can ameliorate this disease by diminishing erythropoiesis (Casu et al., Blood 128, 265-276, 2016).
[0021] Réduction of iron uptake and thereby sérum iron levels may even be bénéficiai in diseases where iron load is normal, such as kidney diseases (Walker and Agarwal, NephroL 36, 6270, 2016), infections with iron-dependent bacteria (Arezes et al., Cell Host Microbe 17, 47-57, 2015), and polymicrobial sepsis (Zeng et al., Anesthesiology, 122, 374-386, 2015).
[0022] Hepcidin itself is limited in its use as a drug because of its complex structure which requires acomplicated manufacturang, and also its limited in vivo duration of action. Continuous 15 efforts hâve been made to search for hepcidin mimetics and Chemical compounds that could be used to increase hepcidin levels.
[0023] A common approach relates to small hepcidin-derived or hepcidin-like peptides, which can be produced affordably, and can be used to treat hepcidin-related diseases and disorders such as those described herein. Such so-called mini-hepcidins are rationally designed small peptides that 20 mimic hepcidin activity and may be useful for the treatment of iron overload, and also iron overload related disease symptoms.
[0024] Such mini-hepcidin peptides are described for example in WO 2010/065815 A2 and WO 2013/086143 Al. WO 2015/157283 Al and the corresponding US 9,315,545 B2 describe hepcidin mimetic peptides and the use thereof in hepcidin-related disorders, such as iron overload, beta25 thalassemia, hemochromatosis etc. and cover a development compound MO 12 ofthe company Merganser Biotech, having been under évaluation in a Phase 1 clinical program as a potentially transformative therapy for a number of hematoiogical diseases including beta-thalassemia, low risk myelodysplasia and polycythemia vera.
[0025] WO 2014/145561 A2 and WO 2015/200916 A2 describe further small hepcidin peptide 30 analogues and the use thereof in the treatment or prévention of a variety of hepcidin-related diseases, including iron overload diseases and iron-loading anémias, and further related disorders.
Further, WO2015/042515 Al relates to hepcidin and its peptide fragments, which are particularly intended for treating rénal ischemia reperfusion injury or acute kidney injury. Further, minihepcidin analogs are described for example by Preza et ai, S. Clin. Invest., I2l (12), 4880-4888, 2011 or in CN 104 Oi l 066 and in WO 2016/109363 Al.
[0026] Ferroportin inhibitors as well as compounds that hâve hepcidin-like activity are needed that also possess additional bénéficiai properties such as improved solubility, stability, and/or potency. An advantage of the ferroportin inhibitor compounds of Formula I described herein is their préparation in sufficient yields by the synthetic routes disclosed herein.

III. Pharmaceutical Compositions and Modes of Administration
[0121] Compounds provided herein are usualiy administered in the form of pharmaceutical compositions. Thus, provided herein are also pharmaceutical compositions that comprise one or more of 5 the compounds described herein or a pharmaceutically acceptable sait, a stereoisomer, or a mixture of stereoisomers thereof and one or more pharmaceutically acceptable vehicles selected from carriers, adjuvants and excipients. Suitabie pharmaceutically acceptable vehicles may include, for example, inert solid diluents and fillers, diluents, includîng stérile aqueous solution and various organic solvents, perméation enhancers, solubilizers and adjuvants. Such compositions are prepared in a manner well known in the pharmaceutical art. See, e.g., Remington’s Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985); and Modem Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G.S. Banker & C.T. Rhodes, Eds.).
[0122] The pharmaceutical compositions may be administered in either single or multiple doses.
The pharmaceutical composition may be administered by various methods includîng, for example, rectal, buccal, intranasal and transdermal routes. In certain embodiments, the pharmaceutical composition may be administered by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, or as an inhalant.
175
[ΟΙ23] One mode for administration is parentéral, for example, by injection. The forms in which the pharmaceutical compositions described herein may be incorporated for administration by injection include, for example, aqueous or oil suspensions, or émulsions, with sesame oil, com oil, cottonseed oil, or peanut oil, as well as élixirs, mannitol, dextrose, or a stérile aqueous solution, and similar pharmaceutical vehicles.
[0124] Oral administration may be another route for administration of the compounds described herein. Administration may be via, for example, capsule or enteric coated tablets. In making the pharmaceutical compositions that include at least one compound described herein or a pharmaceutically acceptable sait, a stereoisomer, or a mixture of stereoisomers thereof, the active ingrédient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of a solid, semisolid, or liquid material, which acts as a vehicle, carrier or medium for the active ingrédient. Thus, the compositions can be in the fonn of tablets, pills, powders, lozenges, sachets, cachets, élixirs, suspensions, émulsions, solutions, syrups, aérosols (as a solid or in a liquid medium), oîntments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, stérile injectable solutions, and stérile packaged powders.
[0125] Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, stérile water, syrup, and methyl cellulose. The formulations 20 can additionally include lubricating agents such as talc, magnésium stéarate, and minerai oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propyIhydroxybenzoates; sweetening agents; and flavoring agents.
[0126] The compositions that include at least one compound described herein or a pharmaceutically acceptable sait, a stereoisomer, or a mixture of stereoisomers thereof can be formulated so as to provide 25 quick, sustained or delayed release of the active ingrédient after administration to the subject by employing procedures known in the art.

The compounds of Formula I as defined herein, act as ferroportin inhibitors and can be used for treating severe forms of b-thalassemia, such as transfusion-dependent b-thalassemia, including in particular bthalassemia major and hemoglobin E b-thalassemia and the symptoms and pathological conditions associated therewith, such as in particular defective red blood cell production in the bone marrow, ineffective erythropoiesis, low hemoglobin levels / anémia, multiple organ dysfunction, iron overload, liver iron loading and cardiac iron overload, paleness, fatigue, jaundice, and splenomegaly.
[0154] In particular, a severe form of b-thalassemia is transfusion-dependent b-thalassemia (TDT), including in particular b-thalassemia major and severe forms of hemoglobin E b- thalassemia. Severe forms of b-thalassemia and hemoglobin E 13- thalassemia, require that patients suffering therefrom achieve regular blood transfusions / Red Blood Cell transfusions (RBC transfusions). Such severe forms of b-thalassemia are thus also summarized as transfUsion-dependent b-thalassemia (TDT).

[0156] The methods of treating beta-thalassemia can resuit in: reduced NTBI levels in a subject;
reduced LPI levels in a subject; reduced alpha globin aggregate levels in a subject; reduced RO S levels in RBCs of a subject; a decrease in liver iron concentration in the subject; a decrease in myocardial iron concentration in the subject; an improvement of at least one of the parameters Hct, MCV, MCH, ROW and réticulocyte numbers in the subject; in an erythroîd response, which comprises a réduction in transfusion burden in the subject; a réduction of transfusion burden in the subject compared to the transfusion burden prior to treatment using the methods; achieving no longer requiring a transfusion in a
183 transfusion-dependent b-thalassemia subject; reduced sérum ferritin levels in the subject; a réduction of the symptoms associated with one or more transfusion-dependent b-thalassemia clinical complications. Nonlimiting examples of transfusion-dependent b-thalassemia symptoms include growth retardation, pallor, jaundice, poor musculature, genu valgum, hepatosplenomegaly, leg ulcers, development of masses from extramedullary hematopoiesis, skeletal changes resulting from expansion of the bone marrow, and clinical complications of chronic red blood cell transfusions, such as, for example hepatitis B virus infection, hepatitis C virus infection and human itnmunodefîcîency virus infection, alloimmunization, and organ damage due to iron overload, such as, for example, liver damage, heart damage and endocrine gland damage. Although the compounds of the formula (1) are not expected to directly affect growth différentiation factor 11 (GDFI1), decrease of skeletal deformities can also occur caused by reduced extramedullary erythropoiesis.
[0157] The foîlowing parameters can be determined to evaluate the efficacy of the compounds of the present invention in the new medical use: sérum iron, NTBI levels, LPI (Labile Plasma Iron) levels, erythropoietin, TSAT (transferrin saturation), Hb (hemoglobin), Hct (haematocrit), MCV (Mean Cell
Volume), MCH (Mean Cell Hemoglobin), RDW (Red Blood Cell Distribution Width) and réticulocyte numbers, complété blood counts, spleen and liver weight, erythropoiesis in spleen and bone marrow, spleen and liver iron content and alpha-globin aggregates in RBC membranes. The détermination can be carried ont using conventional methods of the art, in particular by those described below in more detail. The compounds (I) of the present invention are suitable to improve at least one of these parameters.

In certain aspects of these embodiments, the kidney injuries are those induced by catalytic free iron. In certain aspects of these embodiments, the kidney injuries are selected from rénal ischemia-reperfusion injury (IR1), ischémie injury and acute kidney injuries. In a further aspect, kidney injuries are selected from acute kidney injury (AK!), rénal ischemia-reperfusion injury (IRI), ischémie injury and AKI caused by ischémie injury, AK1 foîlowing surgery or surgical intervention, such as in particular foîlowing cardiac surgery most often with procedures involving cardiopulmonary bypass,
184 other major chest or abdominal surgery, and kidney injury associated with RBC transfusion.

The compounds of the Formula I are suitable for the prévention and treatment of the kidney injuries described herein by 1 imiting reactive oxygen species (ROS) to avoid kidney tissue injury. Further to catalytic free iron, NTBI and LPI (Labile Plasma Iron) can cause kidney injuries. NTBI encompasses ail forms of sérum iron that are not tightly associated with transferrin and is chemtcally and functionally heterogeneous. LPI represents a component of NTBI that is both redox active and chelatable, capable of permeating into organs and inducing tissue iron overload.
[0162] The following parameters can be determined to evaluate the efficacy of the compounds for treating kidney injuries; plasma créatinine, glomerular filtration rate (including estîmated glomerular filtration rate eGFR), urine album in excrétion, urine neutrophil gelatinase-associated lipocaiin (NGAL), NTBI, LPI, RBC hemolysis, blood urea nitrogen (BUN), plasma hemoglobin (Llb), total plasma iron, plasma hepcidin, rénal neutrophil infiltration, sérum IL-6, spleen, kidney and/or liver iron content, rénal ferroportin, KIM-1 (Kidney Injury Molécule- 1) as an acute marker for kidney injury in blood and urine, and H-ferritin. Additionally or alternatively, the efficacy of the compounds of the present invention can be determined via the kidney tubular injury score, such as e.g. the CSA-NGAL score (Cardiac Surgery Associated NGAL Score) for detecting acute tubular damage as described in more detail below, the
KDIGO score described in more detail below or the EGTI score comprising Endothélial, Glomerular, Tubular and Interstitial (EGTI) components to evaluate histology (described e.g, by: Khalid et al.‘

The methods of treating or preventing kidney injury can resuit in a decrease of KIM-1 levels in the subject. The methods of treating or preventing kidney injury can resuit in an increase in spleen and/or liver iron concentration in the subject. The methods of treating or preventing kidney injury can resuit in a decrease in kidney iron concentration in the subject. The methods of treating or preventing kidney injury can resuit in reduced NTBI levels. The methods of treating or preventing kidney injury can resuit in reduced LP1 levels in the subject.

The methods of treating or preventing kidney injury can resuit in a reduced IRI-induced rénal neutrophil infiltration. The methods of treating or preventing kidney injury can resuit in reduced ROS levels in kidney tissue of the subject. The methods of treating or preventing kidney injury can resuit in corrected (increased) kidney H- ferritin levels in the subject. In particular, the methods of treating or preventing kidney injury can reduce the occurrence of AKI, rénal ischemia- reperfusion injury and AKI caused by ischémie injury, AKI following surgery or surgical intervention, such as in particular following cardiac surgery most often with procedures involving cardiopulmonary bypass, other major chest or abdominal surgery, and kidney injury associated with RBC transfusion. The methods of treating or preventing kidney injury can comprise a) decrease, accelerated decrease or prévention of increase of sérum créatinine; and/or b) increase or prévention of decrease of estimated glomerular filtration rate (eGFR); and/or c) decrease or prévention of increase of rénal ferroportin; and/or d) increase or prévention of decrease of H-ferritin levels; and/or e) decrease or prévention of increase of rénal neutrophil infiltration; and/or f) decrease or prévention of increase of sérum IL-6 levels.

[0546] Into a 100-mL 3-necked round-bottom flask, Zn (2.98 g, 45.6 mmol, 3.0 equiv) was suspended in dry (DMF) (30 mL) under nitrogen atmosphère, and iodine (two crystals) was added immediately. A change in color from colorless to dark brown and colorless again was observed. Methyl (2S)-2-[(tert-butoxycarbonyl)amino]-3-iodopropanoate (5.0 g, 15.2 mmol, l .0 equiv), was added followed immediately by iodine (three crystals), the aforementioned color change was observed once more, and the insertion process was allowed to proceed for 2 h. A flask containing CuBr-Me2S (0.3 i g, 1.53 mmol, 0.1 equiv), was placed under vacuum and heated vigorously until the gray CuBr-Me2S became light green/yellow. The flask was then placed under a flow of nitrogen and allowed to cool to room température. This was repeated once more, and the flask was allowed to cool to room température. A prepared solution of Zn Reagent in DMF was transferred to the flask containing CuBr-Me2S (2.06 g,
22.78 mmol, 2.0 equiv), and the reaction was stirred for 72 h at room température. The reaction mixture
356 was then filtered through a silica plug eluting with EtOAc. The organic phase was washed with water (2 x 50 mL) and brine (50 mL). The organic phase was dried with Na2SÛ4, filtered, and the solvent removed under reduced pressure. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (l :50 toi :l). This resulted in 3 g (76.7%) of methyl (2R)-2-[(tertbLitoxycarbonyl)amino]-5-methylhex-5-enoate as an oil. LCMS (ES) [M+1] + m/z: 258.2.

Biological In-Vitro Ferroportin Internalization Assay
[ 1835] The protocol for this assay is generally as described in WO2018/128828, incorporated herein by reference in its entirety. Functîonal internalization of ferroportin protein was measured using a stably-transfected CHO cell line expressing the human ferroportin tagged to a lucîferase reporter. Cells were plated for 24h in the presence of ferrie ammonium citrate (FAC). Ferroportin protein expression was induced with doxycycline for 24 h. The next day, the compounds were added. Test compounds were dissolved in DMSO. Cells were incubated with the test compounds for 6 h, and subsequently lucîferase activity was measured using the Nano-Glo Lucîferase Assay System and Glomax (Promega, Madison, WI).
[1836] The average pECso was determined for the test compounds. The data is provided in Table 2 below.
