This application claims the benefit and priority of U.S. Provisional Application No. 62/687068, filed June 19, 2018, the entire contents of which are incorporated herein in their entirety by reference.

The field of technology to which the invention belongs

The present invention relates to N-substituted tetrahydrothienopyridine derivatives, pharmaceutical formulations containing them, and their use in the prevention and treatment of viral infections, in particular viral infections caused by dengue virus.

Background of the invention

Dengue is the most common human viral (arbovirus) disease transmitted by arthropods and continues to be a global public health problem. Dengue fever is a febrile disease caused by one of four dengue virus serotypes: DEN-1, DEN-2, DEN-3 and DEN-4, which belong to the Flaviviridae family. The virus is transmitted to humans primarily by the Aedes aegypti mosquito, which feeds on human blood.

Infections have a range of clinical manifestations, from milder flu-like symptoms to more severe and sometimes fatal bleeding disorders. Typical symptoms include fever, severe headache, muscle and joint pain, and rash. The most severe forms of the disease are dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). According to the WHO, there are four main clinical manifestations of DHF: (1) high fever (2) hemorrhagic events (3) thrombocytopenia and (4) plasma leakage. The definition of DSS includes the definition of DHF plus a weak rapid pulse and low pulse pressure or hypotension with cold, clammy skin and an agitated state. The severity of DHF can be reduced by early detection and intervention, but patients in shock have a high risk of death.

Approximately 390 million people are affected each year, 96 million of whom show clinical signs of the disease. According to the WHO, the number of reported cases increased from 2.2 million in 2010 to 3.2 million in 2015. Prior to 1970, only 9 countries experienced severe dengue epidemics. Dengue is now endemic in more than 100 countries in WHO monitored regions in Africa, the Americas, the Eastern Mediterranean, Southeast Asia and the Western Pacific. The most difficult situation is observed in the regions of North and South America, Southeast Asia and the Western Pacific. A quarter of those infected will require hospitalization, of which 3-6% may progress to dengue hemorrhagic fever or shock syndrome, which is a fatal manifestation of the disease. The number of deaths in 2012 was estimated by WHO to be approximately 12,500; however, this number is believed to be grossly underestimated due to unreported details of most cases. The danger of developing lethal forms of dengue and the social costs of dengue patients justify the costs of developing and commercializing an anti-dengue drug, which will be offset by savings in hospitalization and disability costs.

Despite regular outbreaks, previously infected people remain susceptible to infection because there are four different dengue virus serotypes, and infection with one of these serotypes confers immunity to that serotype only. DHF is thought to occur more frequently in individuals who have secondary dengue infections. The search for effective treatments for dengue fever, DHF and DSS is currently underway.

Yellow fever virus (YFV), West Nile virus (WNV), Japanese encephalitis virus (JEV), tick-borne encephalitis virus, Kunjin virus, Australian encephalitis, American encephalitis, Omsk hemorrhagic fever virus, viral bovine diarrhea, Zika virus and virus hepatitis C (HCV) also belong to the Flaviviridae family.

WNV may be asymptomatic or cause flu-like symptoms in some people. In some cases, this causes neurological disorders, encephalitis, and in severe cases can lead to death. WNV is also transmitted by mosquitoes. YFV is also transmitted by mosquitoes and can present with severe symptoms in infected people. JEV is also transmitted by mosquitoes and is either asymptomatic or with flu-like symptoms, and in some cases encephalitis develops. The disease stage of acute encephalitis is characterized by seizures, stiff neck muscles, and other symptoms. HCV is a blood-borne virus that is transmitted through the blood. At the initial (acute) stage of the disease, no symptoms are observed in most patients. Even during the chronic stage (i.e., when the illness lasts longer than 6 months), the severity of symptoms can vary from person to person. Over time, some infected people may develop cirrhosis or liver cancer. Modern treatment for HCV involves a combination of interferon alfa and ribavirin, an antiviral drug. Efficient treatments for infections caused by these Flaviviridae viruses are also being sought.

The present invention relates to N-substituted tetrahydrothienopyridine derivatives which are useful in the treatment of viral infections such as those caused by a virus of the Flaviviridae family, especially dengue virus, yellow fever virus, West Nile virus,

- 1 041825 Japanese encephalitis virus, tick-borne encephalitis virus, Kunjin virus, Australian encephalitis, American encephalitis, Omsk hemorrhagic fever virus, bovine viral diarrhea, Zika virus and hepatitis C virus, as well as other Flaviviridae viruses, as described in this document.

In this context, the term substituted means that at least one hydrogen atom is replaced by a group other than hydrogen, provided that the normal valences are maintained, and that the substitution results in a stable compound. If the substituent is a ketone group (i.e. =O), then 2 hydrogens are replaced on the atom. Ketone substituents are not present in aromatic moieties. When a ring (eg, carbocyclic or heterocyclic) system is said to be substituted with a carbonyl group or double bond, the carbonyl group or double bond is meant to be part of (ie, within) the ring. Double ring bonds in this context are double bonds formed between two adjacent atoms in the ring (eg C=C, C=N or N=N).

Where nitrogen atoms (eg, amines) are present in the compounds of the present invention, they can be converted to N-oxides by treatment with oxidizing agents (eg, mCPBA and/or hydrogen peroxides) to give other compounds of the present invention. Thus, the nitrogen atoms shown and claimed are intended to encompass both the shown nitrogen and its N-oxide (N^O) derivative.

When a variable occurs more than once in any component or compound formula, its definition in each instance is independent of its definition in every other instance. Thus, for example, if a group is shown to be substituted with 0 to 3 R's, then that group may be unsubstituted or substituted with no more than three R's, and in each case R is chosen regardless of the definition of R.

In this context, RV is a symbol indicating the point of attachment of R to another part of the molecule.

If a bond to a substituent is shown to cross a bond connecting two atoms in the ring, then such substituent may be bonded to any atom in the ring. If a substituent is listed without specifying the atom through which such substituent is bonded to the remainder of a compound of a given formula, then such substituent may be bonded through any atom in that substituent.

Combinations of substituents and/or variables are allowed only if such combinations result in stable compounds.

The phrase pharmaceutically acceptable indicates that the substance or formulation must be compatible chemically and/or toxicologically with the other ingredients contained in the formulation and/or with the mammal being exposed to it.

Unless otherwise indicated, the expression compound of the present invention or compounds of the present invention refers to compounds of formula (I), (IA), (IB) or (IC), as well as isomers such as stereoisomers (including diastereoisomers, enantiomers and racemates), geometric isomers, conformational isomers (including rotamers and atropisomers), tautomers, isotopically labeled compounds (including those substituted with deuterium), and naturally formed moieties (eg, polymorphs, solvates, and/or hydrates). Where a salt-forming moiety is present, salts, in particular pharmaceutically acceptable salts, are also included.

Those skilled in the art will appreciate that the compounds of the present invention may contain chiral centers and therefore may exist in various isomeric forms. As used herein, the term isomers refers to various compounds that have the same molecular formula but differ in the arrangement and configuration of the atoms.

Enantiomers are a pair of stereoisomers that are mismatched mirror images of each other. A 1:1 mixture of enantiomer pairs is a racemic mixture. This term is used to refer to a racemic mixture where appropriate. When assigning stereochemistry to compounds of the present invention, one stereoisomer with a known relative and absolute configuration of the two chiral centers is designated using the conventional RS system (eg, (1S,2S)); one stereoisomer with a known relative configuration but an unknown absolute configuration is indicated by asterisks (eg (1R*,2R*)); and a racemate with two letters (for example, (1RS,2RS) means a racemic mixture of (1R,2R) and (1S,2S); (1RS,2SR) means a racemic mixture of (1R,2S) and (1S,2R)).

Diastereoisomers are stereoisomers that have at least two asymmetric atoms, but which are not mirror images of each other. Absolute stereochemistry is given according to the Cahn-Ingold-Prelog R-S system. If the compound is the pure enantiomer, the stereochemistry at each chiral carbon may be indicated as either R or S. Separated compounds whose absolute configuration is unknown may be indicated as (+) or as (-) depending on the direction (right- or left-handed), in which they rotate plane-polarized light at a wavelength D of the sodium line. Alternatively, separated compounds can be determined using the respective retention times for the respective enantiomers/diastereoisomers by chiral HPLC.

Some of the compounds described in this document contain one or more asymmetric centers or axes and thus can form enantiomers, diastereoisomers and other stereoisomeric forms, which in terms of absolute stereochemistry can be denoted as (R)- or (S )-.

Geometric isomers can occur when a compound contains a double bond or some other feature that gives the molecule a certain degree of structural rigidity. If the compound contains a double bond, the substituent may have the E or Z configuration. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may be in the cis or trans configuration.

Conformational isomers (or conformers) are isomers that can differ in rotation around one or more bonds. Rotamers are conformers that differ from each other in rotation about only a single bond.

The term atropisomer refers to a structural isomer based on axial or planar chirality resulting from the impossibility of rotation in the molecule.

Unless otherwise indicated, the compounds of the present invention are intended to include all such possible isomers, including racemic mixtures, optically pure forms, and mixtures of intermediates. Optically active (R)- and (S)-isomers can be prepared using chiral synthons or chiral reagents, or isolated using conventional techniques (e.g., separated on chiral SFC or HPLC chromatography columns such as CHIRALPAK® and CHTRALCEL®, which are commercially available from DAICEL Corp., using a suitable solvent or mixture of solvents to achieve proper separation).

The compounds of the present invention may be isolated in optically active or racemic forms. Optically active forms can be obtained by resolution of racemic forms or by synthesis from optically active starting materials. All methods used to obtain the compounds of the present invention, and intermediate compounds obtained within these methods, are considered part of the present invention. If enantiomeric or diastereomeric products are obtained, they can be separated by conventional methods, for example chromatographically or by fractional crystallization.

Depending on the process conditions, the end products of the present invention are obtained either in free (neutral) form or in salt form. Both the free form and the salts of these end products are within the scope of this invention. If required, one form of connection can be converted to another form. A free base or acid can be converted to a salt; the salt can be converted to the free compound or another salt; a mixture of isomeric compounds of the present invention can be separated into individual isomers.

Pharmaceutically acceptable salts are preferred. However, other salts may be useful, for example, in isolation or purification steps, the latter can be used during preparation, and therefore they are covered by the scope of this invention.

As used herein, pharmaceutically acceptable salts refer to derivatives of the disclosed compounds wherein the parent compound is modified by converting it to acidic or basic salts. For example, pharmaceutically acceptable salts include, but are not limited to, salt forms such as acetate, ascorbate, adipate, aspartate, benzoate, besylate, bromide/hydrobromide, bicarbonate/carbonate, bisulfate/sulfate, camphorsulfonic acid salt, capric acid salt, chloride. /hydrochloride, chlorotheophyllonate, citrate, ethanedisulfonate, fumarate, gluceptate, gluconate, glucuronate, glutamate, glutarate, glycolate, hippurate, hydroiodide/iodide, isethionate, lactate, lactobionate, lauryl sulfate, malic acid salt, maleic acid salt, malonate/hydroxymalonate, salt mandelic acid, mesylate, methyl sulfate, mucic acid salt, naphthoic acid salt, napsilate, nicotinate, nitrate, octadecanoate, oleate, oxalate, palmitate, pamoate, phenylacetate, phosphate/hydrophosphate/dihydrogen phosphate, polygalacturonate, propionate, salicylates, stearate, succinate, sulfamate , sulfosalicylate, tartrate, tosylate, trifluoroacetate, or xinafoate.

Inorganic acids with which salts can be formed include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid and the like, hydrochloric acid is preferred. Organic acids with which salts can be prepared include, for example, acetic acid, propionic acid, glycolic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, toluenesulfonic acid, sulfosalicylic acid, and the like.

Pharmaceutically acceptable base addition salts can be formed using inorganic and organic bases. Inorganic bases with which salts can be formed include, for example, ammonium salts and metals from Groups I-XII of the Periodic Table of the Elements. In certain embodiments, salts are prepared using sodium, potassium, ammonium, calcium, magnesium, iron, silver, zinc, and copper; in particular, suitable salts include the ammonium, potassium, sodium, calcium and magnesium salts. Organic bases with which salts can be formed include, for example, primary, secondary, and tertiary amines, substituted amines, including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like. Certain organic amines include isopropylamine, benzathine, cholinate, diethanolamine, diethylamine, lysine, meglumine, piperazine, and tromethamine.

Pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound containing a basic or acidic moiety using standard chemical methods. Such salts can generally be prepared by reacting these compounds in their free acid or base form with a stoichiometric amount of an appropriate base or acid in water, or in an organic solvent, or a mixture of both; non-aqueous media such as ether, ethyl acetate, ethanol, isopropanol or acetonitrile are generally preferred. Lists of suitable salts can be found in Allen, L.V., Jr., ed., Remington: The Science and Practice of Pharmacy, 22nd Edition, Pharmaceutical Press, London, UK (2012), the invention of which is incorporated herein by reference.

Compounds of this invention containing groups capable of acting as hydrogen bond donors and/or acceptors may be capable of forming co-crystals with suitable means for forming co-crystals. Such co-crystals can be obtained from the compounds of the present invention by known procedures for the formation of co-crystals. Such procedures include grinding, heating, co-sublimation, co-melting, or contacting the compounds of the present invention with a co-crystal forming agent in solution under crystallization conditions, and separating the co-crystals thus formed.

Any formula given herein also implies the presence of unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted using the formulas given herein, except that one or more atoms are replaced by an atom characterized by the selected atomic mass or mass number. Examples of isotopes that can be included in the compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ² H, ³ H, ⁿ C, ¹³ C, ¹⁴ C, ¹⁵ N, ¹⁸ F , ³¹ P, ³² P, ³⁵ S, ³⁶ Cl, and ¹²⁵ I, respectively. This invention includes various isotopically labeled compounds as defined herein, for example those in which radioactive isotopes such as ³ H, ¹³ C and ¹⁴ C are present. Such isotopically labeled compounds are useful in metabolic studies (using ¹⁴ C), reaction kinetics (using, for example, ² H or ³ H), detection or imaging techniques such as positron emission tomography (PET) or single photon emission computed tomography (SPECT), including analyzes of drug or substrate distribution in tissues, or in radiation therapy patients. In particular, ¹⁸ F or a labeled compound may be particularly useful for PET or SPECT studies. Isotopically labeled compounds of the present invention can generally be prepared using the procedures disclosed in the Schemes or in the Examples and Preparations described below by replacing a readily available isotopically labeled reagent with a non-isotopically labeled reagent.

In addition, substitution with heavier isotopes, in particular deuterium (i.e. ² H or D), may provide certain therapeutic advantages due to higher metabolic stability, such as an increase in in vivo half-life, or a reduction in the required dosage, or an improvement in therapeutic index. It is understood that deuterium in this context is considered as a substituent in the compound of the present invention. The concentration of such a heavier isotope, in particular deuterium, can be determined by the isotope enrichment factor. As used herein, the term isotope enrichment ratio means the ratio between the abundance of an isotope and the natural abundance of said isotope. When a substituent in a compound of the present invention is said deuterium, such compound has an isotopic enrichment factor for each designated deuterium atom of at least 3500 (introduction of 52.5% deuterium per designated deuterium atom), at least 4000 ( deuterium injection 60%), at least 4500 (deuterium injection 67.5%), at least 5000 (deuterium injection 75%), at least 5500 (deuterium injection 82.5%), at least 6000 (deuterium injection 90%), at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation), at least 6600 (99% deuterium incorporation), or at least 6633.3 (deuterium incorporation 99.5%.

Isotopically labeled compounds of the present invention can generally be prepared by conventional procedures known to those skilled in the art, or by methods similar to those described herein, using an appropriate isotopically labeled reagent instead of the conventional unlabeled reagent. Such compounds can in principle be used, for example, as standards and reagents in determining the ability of a potential pharmaceutical compound to bind to target proteins or target receptors, or to visualize the binding of compounds of this invention to biological receptors in vivo or in vitro.

A stable compound and a stable structure are intended to indicate a compound that is stable enough to withstand isolation from the reaction mixture with the required

Flavivirus immunodetection based on highly detailed cell microscopy (HCI-CFI).

A549 cells (7x10 ³ cells per well) in a 384-well plate were infected with DENV-2 strain (MY97-10340) at an MOI of 0.3. The cells were then treated with 3-fold 10-point serial dilutions of the test compound. After 48 hours, cells were fixed with paraformaldehyde and viral E protein was detected with Dylight™ 488 labeled 4G2 antibody (GenScript). Cell nuclei were stained using Draq5 (Pierce/Thermo) and images were acquired on an Opera imaging system (Perkin Elmer). A dose-response curve was constructed to calculate the effective compound concentration required to reduce protein E expression by 50% (EC ₅ o) using GraphPad Prism. The obtained values of the EU ₅₀ are given in table. 1 below: +>1 μM; 1 µM>++>0.1 µM; 0.1 µM>+++.
