Abstract
Description
[Technical Field]
[0001] This application relates to the pharmaceutical field, and more particularly to prodrugs of integrase inhibitors and uses thereof. [Background technology]
[0002] Significant progress has been made in developing effective diagnostics and treatments for human immunodeficiency virus type 1 (HIV-1). Antiretroviral therapy (ART) has significantly reduced disease-related morbidity and mortality, thereby enabling infected individuals to achieve a near-normal quality of life. However, ART requires lifelong treatment to suppress viral replication and prevent the development of AIDS.
[0003] Additionally, the effectiveness of ART can be hindered by HIV-1 resistance, drug toxicity, and poor patient adherence. Treatment fatigue, lack of financial and social support, comorbid psychiatric symptoms, and / or substance abuse can all contribute to poor adherence to important ART regimens. Dolutegravir (DTG), cabotegravir (CAB), and bictegravir (BTG) are types of integrase inhibitors or integrase strand transfer inhibitors (INSTIs). Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION
[0009] The following description includes some specific details to provide a thorough understanding of the various disclosed embodiments. However, one skilled in the relevant art will recognize that the embodiments may be practiced with other methods, components, materials, etc., without one or more of these specific details.
[0010] Unless otherwise required herein, throughout the specification and claims, the terms "comprise" and "comprising" are to be interpreted in an open and inclusive sense, i.e., "including, but not limited to."
[0011] As used in this application and the claims, reference to the singular without a designation of quantity is intended to include reference to the plural unless the context clearly dictates otherwise.
[0012] Throughout this specification, the references to "one embodiment," "one embodiment," "another embodiment," or "in some embodiments" mean that at least one embodiment includes the particular referenced element, structure, or feature associated with that embodiment. Thus, the appearances of the phrases "in one embodiment," "in one embodiment," "in another embodiment," or "in some embodiments" in various places throughout the specification do not necessarily refer to the same embodiment. Furthermore, particular elements, structures, or features may be combined in any suitable manner in one or more embodiments.
[0013] As used in the specification and claims of this application, the singular forms "a," "an," and "the" should be understood to include plural referents unless the context clearly dictates otherwise. Thus, for example, a sustained-release tablet referring to a "pharmaceutically acceptable excipient" includes a pharmaceutically acceptable excipient, or two or more pharmaceutically acceptable excipients.
[0014] definition Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. A dashed line at the beginning or end of a chemical group is intended to facilitate indicating the point of attachment to the parent molecule, and a chemical group may be depicted with or without one or more dashed lines without losing its ordinary meaning. "C u-v " or "C u -C v " indicates that the group below has u to v carbon atoms, where u and v are integers. For example, "C 1-6 By "alkyl group" or "C1-C6 alkyl group" it is meant that the alkyl group has from 1 to 6 carbon atoms.
[0015] An "alkyl group" is a monovalent or divalent, straight- or branched-chain saturated hydrocarbon group. For example, an alkyl group can be a group having 1 to 10 carbon atoms (i.e., C 1-10 alkyl group), 1 to 8 carbon atoms (i.e., C 1-8 alkyl group), 1 to 6 carbon atoms (i.e., C 1-6 alkyl group), or 1 to 4 carbon atoms (i.e., C 1-4 alkyl group).
[0016] Examples of alkyl groups include methyl (Me, -CH), ethyl (Et, -CHCH), 1-propyl (n-Pr, n-propyl, -CHCHCH), 2-propyl (i-Pr, isopropyl, -CH(CH)), 1-butyl (n-Bu, n-butyl, -CHCHCHCH), 2-methyl-1-propyl (i-Bu, isobutyl, -CHCH(CH)), 2-butyl (s-Bu, s-butyl, -CH H(CH3)CH2CH3), 2-methyl-2-propyl group (t-Bu, t-butyl group, -C(CH3)3), 1-pentyl group (n-pentyl group, -CH2CH2CH2CH3), 2-pentyl group (-CH(CH3)CH2CH3), 3-pentyl group (-CH(CH2CH3)2), 2-methyl-2-butyl group (-C(CH3)2CH2CH3), 3-methyl-2-butyl group (-CH(CH3)CH(CH3)2), 3-methyl-1-butyl group (- CH2CH2CH(CH3)2), 2-methyl-1-butyl group (-CH2CH(CH3)CH2CH3), 1-hexyl group (-CH2CH2CH2CH3), 2-hexyl group (-CH(CH3)CH2CH2CH3), 3-hexyl group (-CH(CH2CH3)(CH2CH2CH3)), 2-methyl-2-pentyl group (-C(CH3)2CH2CH2CH3), 3-methyl-2-pentyl group (-CH(CH3)CH(CH3)CH2CH3), 4 Examples of alkyl groups include, but are not limited to, 3-methyl-2-pentyl (-CH(CH3)CH2CH(CH3)2), 3-methyl-3-pentyl (-C(CH3)(CH2CH3)2), 2-methyl-3-pentyl (-CH(CH2CH3)CH(CH3)2), 2,3-dimethyl-2-butyl (-C(CH3)2CH(CH3)2), 3,3-dimethyl-2-butyl (-CH(CH3)C(CH3)3), and octyl (-(CH2)7CH3). Alkyl groups can be unsubstituted or substituted.
[0017] An "alkenyl group" is a monovalent or divalent, straight- or branched-chain hydrocarbon group having at least one carbon-carbon double bond. For example, an alkenyl group can be an alkyl group having 2 to 8 carbon atoms (i.e., C 2-8 alkenyl groups), 2 to 6 carbon atoms (i.e., C2-6 alkenyl groups), or 2 to 4 carbon atoms (i.e., C 2-4 Examples of alkenyl groups include, but are not limited to, -CH=CH, -CHCH=CH, and -CH-CH=CH-CH. Alkenyl groups can be unsubstituted or substituted.
[0018] An "alkynyl group" is a monovalent or divalent, straight- or branched-chain hydrocarbon group having at least one carbon-carbon triple bond. For example, an alkynyl group can be an alkynyl group having 2 to 8 carbon atoms (i.e., C 2-8 alkynyl groups), 2 to 6 carbon atoms (i.e., C 2-6 alkynyl groups), or 2 to 4 carbon atoms (i.e., C 2-4 Examples of alkynyl groups include, but are not limited to, -C≡CH, -CHC≡CH, and -CH-C≡C-CH. Alkynyl groups can be unsubstituted or substituted.
[0019] An "alkoxyalkyl group" is a group formed by linking an alkoxy group to a divalent alkyl group (as defined above for alkyl groups). For example, C 2-6 Alkoxyalkyl groups include -CH2-OMe, -CH2-O-iPr, -CH2-CH2-OMe, -CH2-CH2-O-CH2-CH3 and -CH2-CH2-O-tBu. Alkoxyalkyl groups can be unsubstituted or substituted.
[0020] "Halogen" refers to fluorine (-F), chlorine (-Cl), bromine (-Br) and iodine (-I).
[0021] A "haloalkyl group" is an alkyl group, as defined herein, where one or more hydrogen atoms of the alkyl group are independently replaced with a halogen, which may be the same or different, making the alkyl group divalent. The alkyl group and halogen may be any one of those described above. In some embodiments, the haloalkyl group determines the number of carbon atoms in the alkyl group portion, e.g., C 1-4 Haloalkyl groups include CF3, CH2F, CHF2, CH2CF3, CH2CH2CF3, CCl2CH2CH3, and C(CH3)2(CF2H). Haloalkyl groups can be unsubstituted or substituted.
[0022] "Aryl group" refers to a monovalent or divalent, mono-fused or poly-fused, all-carbon, aromatic ring system, wherein the rings are aromatic. For example, in some embodiments, an aryl group has 6 to 20 carbon atoms, 6 to 14 carbon atoms, 6 to 12 carbon atoms, or 6 to 10 carbon atoms. Aryl groups include a phenyl group. Aryl groups also include multiple fused ring systems (e.g., ring systems consisting of 2, 3, or 4 rings) having about 9 to 20 carbon atoms, wherein the multiple rings are aromatic. Where valency requirements permit, the rings of multiple fused ring systems can be linked together by fused bonds.
[0023] Furthermore, when referring to an aryl group having a certain range of atoms (e.g., a 6- to 10-membered aryl group), it should be understood that the range of atoms refers to the total number of atoms in the aryl group ring. For example, a 6-membered aryl group includes a phenyl group, and a 10-membered aryl group includes a naphthyl group. Non-limiting examples of aryl groups include, but are not limited to, a phenyl group, a naphthyl group, an anthracenyl group, and the like. An aryl group may be unsubstituted or substituted.
[0024] "Alkylaryl group" refers to an alkyl group, as defined herein, where one or more hydrogen atoms of the alkyl group are independently replaced with an aryl group, where the aryl groups can be the same or different. The alkyl and aryl groups can be any one of those described above. Such alkyl groups are divalent. In some embodiments, the alkylaryl group has 7 to 24 carbon atoms, 7 to 16 carbon atoms, 7 to 13 carbon atoms, or 7 to 11 carbon atoms. An alkylaryl group defined by the number of carbon atoms refers to the total number of carbon atoms present in the alkyl and aryl groups. For example, a C7 alkylaryl group refers to a benzyl group, while a C7 alkylaryl group refers to a C 11 Alkylaryl groups include 1-methylnaphthalene and n-pentylphenyl groups.
[0025] In some embodiments, the number of carbon atoms in the alkyl and aryl group moieties can each be independently designated, e.g., C 1-6 Alkyl group-C 6-10 Aryl groups. Non-limiting examples of alkylaryl groups include, but are not limited to, benzyl, 2,2-dimethylphenyl, n-pentylphenyl, 1-methylnaphthyl, 2-ethylnaphthyl, etc. Alkylaryl groups can be unsubstituted or substituted.
[0026] A "5- to 10-membered aromatic heterocycle" or "heteroaromatic ring" refers to a single aromatic ring having at least one atom other than carbon in the ring, where said atom is selected from the group consisting of oxygen, nitrogen, and sulfur; a "heteroaryl group" also includes fused ring systems having at least one aromatic ring of this type, which are further described below.
[0027] Thus, a "heteroaryl group" comprises a single aromatic ring having about 1 to 6 carbon atoms and about 1 to 4 heteroatoms selected from the group consisting of oxygen, nitrogen, and sulfur. The sulfur and nitrogen atoms can also be present in oxidized form, so long as the ring is aromatic. Exemplary heteroaryl ring systems include, but are not limited to, pyridyl, pyrimidinyl, oxazolyl, or furanyl groups.
[0028] The term "heteroaryl group" further includes multiple fused ring systems (e.g., ring systems consisting of 2, 3, or 4 rings), where a heteroaryl group as defined above is fused to one or more rings selected from the group consisting of heteroaryl groups (e.g., to form a 1,8-naphthyridinyl group) and aryl groups (e.g., to form a benzimidazolyl or indazolyl group) to form a multiple fused ring system. Thus, a heteroaryl group (single aromatic ring or multiple fused ring system) may have about 1 to 20 carbon atoms and about 1 to 6 heteroatoms in the heteroaryl ring.
[0029] For example, a tetrazolyl group has one carbon atom and four nitrogen heteroatoms in the ring. Where valency requirements permit, the rings of multiple fused ring systems can be connected to each other through fused bonds. It is understood that the rings of multiple fused ring systems can be connected to each other in any order. It should be understood that the connection point of a heteroaryl group or heteroaryl group poly-fused ring system can be any suitable atom of the heteroaryl group or heteroaryl group poly-fused ring system, including carbon atoms and heteroatoms (e.g., nitrogen).
[0030] It should also be understood that when referring to a heteroaryl group having a range of atoms (e.g., a 5- to 10-membered heteroaryl group), the range of atoms refers to the total number of atoms in the heteroaryl ring, including carbon atoms and heteroatoms.
[0031] It should also be understood that the rings of the multiple fused ring system may include an aryl group ring fused to a heterocycle having saturated or partially unsaturated bonds (e.g., a 3-, 4-, 5-, 6-, or 7-membered ring) and having about 1 to 6 ring carbon atoms and about 1 to 3 cycloheteroatoms selected from oxygen, nitrogen, and sulfur in the ring.
[0032] For example, a 5-membered heteroaryl group includes a thiazolyl group, and a 10-membered heteroaryl group includes a quinolyl group. Exemplary heteroaryl groups include, but are not limited to, pyridyl, pyrrolyl, pyrazinyl, pyrimidinyl, pyrazolyl, thienyl, indolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, furanyl, oxadiazolyl, thiazolyl, quinolyl, isoquinolyl, benzothiazolyl, benzoxazolyl, indazolyl, quinoxalyl, quinozolinyl, benzofuranyl, benzimidazolyl, phenylthio, pyrrolo[2,3-b]pyridyl, quinazolinyl-4(3H)-one, triazolyl, and tetrazolyl. Heteroaryl groups can be unsubstituted or substituted.
[0033] A "cycloalkyl group" is a monovalent or divalent all-carbon ring or multiple fused all-carbon ring system, wherein the ring in each embodiment is a non-aromatic saturated or unsaturated ring. For example, in some embodiments, the cycloalkyl group has 3 to 12 carbon atoms, 3 to 10 carbon atoms, 3 to 8 carbon atoms, 3 to 6 carbon atoms, 3 to 5 carbon atoms, or 3 to 4 carbon atoms. Exemplary monocyclic cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloalkenyl, cycloheptyl, cycloheptenyl, and cyclooctyl groups.
[0034] Cycloalkyl groups also include multiple fused ring systems (e.g., ring systems containing two rings) having about 7 to 12 carbon atoms. Where valence requirements permit, the rings of multiple fused ring systems may be connected to each other by fused, spiro, or bridged bonds. Exemplary multicyclic cycloalkyl groups include octahydropentene, bicyclo[2.2.1]heptane, bicyclo[2.2.2]octane, bicyclo[2.2]oct-2-ene, and spiro[2.5]octane. Cycloalkyl groups can be unsubstituted or substituted.
[0035] As used herein, a "heterocycle," "heterocyclic ring," or "heterocyclic group" refers to a single saturated or partially unsaturated non-aromatic ring or non-aromatic polycyclic ring system having at least one heteroatom in the ring (i.e., at least one cyclic (i.e., ring-shaped) heteroatom selected from oxygen, nitrogen, and sulfur). Unless otherwise specified, a heterocyclic group has 3 to about 20 ring atoms, e.g., 3 to 12 ring atoms, e.g., 4 to 12 ring atoms, 4 to 10 ring atoms, 3 to 8 ring atoms, 3 to 6 ring atoms, 4 to 6 ring atoms, or 4 to 5 ring atoms.
[0036] Thus, the term includes a single saturated or partially unsaturated ring (e.g., a 3-, 4-, 5-, 6-, or 7-membered ring) having about 1 to 6 ring carbon atoms and about 1 to 3 cycloheteroatoms, the heteroatoms in which are selected from the group consisting of oxygen, nitrogen, and sulfur. Where valency requirements permit, rings of multiple fused rings (e.g., bicycloheterocycles) may be linked together by fused, spiro, and bridged bonds.
[0037] Heterocycles include azacyclo, aziridine, imidazolidine, morpholine, ethylene oxide, thiacyclo, piperazine, piperidine, pyrazolidineamine, piperidine, pyrrolidine, pyrrolidone, tetrahydrofuran, tetrahydrothiophene, dihydropyridine, tetrahydropyridine, quinuclidine, 2-oxo-6-azaspiro[3.3]hept-6-yl, 6-oxa-1-azaspiro[3.3]hept-6-yl, and 1-azaspiro[3.3]hept-6-yl. 2-azabicyclo[3.1.0]hex-2-yl, 3-azabicyclo[3.0]hexyl, 2-azabicyclo[2.1.1]hexyl, 2-azabicyclo[2.2.1]hept-2-yl, 4-azaspiro[2.4]heptyl, 5-azaspiro[2.4]heptyl, and the like.
[0038] The heterocyclic group can be unsubstituted or substituted.
[0039] "Alkylheteroaryl group" refers to an alkyl group, as defined herein, where one or more hydrogen atoms of the alkyl group are independently replaced with heteroaryl groups, where the heteroaryl groups can be the same or different, thereby making the alkyl group divalent. The alkyl group and heteroaryl group can be any one of the above.
[0040] In some embodiments, the number of atoms in the alkyl and heteroaryl groups can be adjusted to, for example, C 1-6 The alkyl group may be separately designated as a 5- to 10-membered heteroaryl group, where each heteroatom is independently N, O, or S. The alkylheteroaryl group may be unsubstituted or substituted.
[0041] "Oxo" refers to =O.
[0042] As used herein, "substituted" refers to one or more hydrogen atoms of the group therein being independently replaced with one or more substituents (eg, 1, 2, 3, 4 or more).

[0045] As used herein, a "therapeutically effective amount" or "effective amount" refers to an amount that effectively induces a desired biological or medical response, and includes an amount of a compound that, when administered to a subject to treat a disease, is sufficient to affect treatment for that disease. The effective amount varies depending on factors such as the compound, the disease and its severity, and the age and weight of the subject being treated. The effective amount can include a range of amounts.
[0046] As is understood in the art, an effective amount may be one or more doses, i.e., one dose or multiple doses may be required to achieve the desired therapeutic goal. An effective amount is considered when administering one or more therapeutic agents, and a single agent can be considered to be administered in an effective amount if it is likely to achieve, or has already achieved, an ideal or beneficial result in combination with one or more other agents. The combined effect of the compounds (e.g., additive or synergistic effect) can selectively reduce the appropriate dose of any co-administered compound.
[0047] As used herein, "co-administered" refers to administering a unit dose of a compound of the present disclosure before or after administering a unit dose of one or more additional therapeutic agents, e.g., administering a compound of the present disclosure within seconds, minutes, or hours of administering one or more additional therapeutic agents. For example, in some embodiments, a unit dose of a compound of the present disclosure is administered first, followed by administration of a unit dose of one or more additional therapeutic agents within seconds or minutes.
[0048] Alternatively, in other embodiments, a unit dose of one or more additional therapeutic agents is administered first, followed within seconds or minutes by a unit dose of a compound of the present disclosure. In some embodiments, a unit dose of a compound of the present disclosure is administered first, followed several hours (e.g., 1-12 hours) later by a unit dose of one or more additional therapeutic agents.
[0049] In other embodiments, a unit dose of one or more additional therapeutic agents is administered first, followed several hours (e.g., 1-12 hours) later by a unit dose of a compound of the present disclosure. Co-administration of a compound disclosed herein with one or more additional therapeutic agents generally refers to simultaneous or sequential administration of a compound disclosed herein and one or more additional therapeutic agents such that a therapeutically effective amount of each agent is present in the subject's body.
[0050] Further provided are pharmaceutically acceptable salts, hydrates, solvates, isomeric forms, polymorphs and prodrugs of the compounds described herein.
[0051] "Pharmaceutically acceptable" or "physiologically acceptable" refers to compounds, salts, compositions, dosage forms and other materials useful in preparing pharmaceutical compositions suitable for use in veterinary or human medicine.
[0052] The compounds described herein may be prepared and / or formulated as pharmaceutically acceptable salts, or, where appropriate, as free bases. Pharmaceutically acceptable salts are non-toxic salts of the free base form of the compounds, which salts possess the pharmacological activity of the desired free base. These salts can be extracted from inorganic or organic acids or bases.
[0053] For example, compounds containing a basic nitrogen can be prepared into pharmaceutically acceptable salts by contacting the compound with an inorganic or organic acid. Non-limiting examples of pharmaceutically acceptable salts include sulfate, pyrosulfate, disulfite, disulfate, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, propionate, decanoate, octanoate, acrylate, formate, isobutyrate, caproate, enanthate, propanolate, oxalate, malonate, ferrite, sebacate, fumarate, maleate, butyne-1,4 diacid, hexyne-1,6-diacid, and the like.

[0055] Examples of "pharmaceutically acceptable salts" of the compounds disclosed herein further include alkali metal (e.g., sodium, potassium), alkaline earth metal (e.g., magnesium), ammonium, and N(C1-C4 alkyl) salts. 4+Also included are salts from appropriate bases such as sodium or potassium salts.
[0056] Further provided are compounds described herein or pharmaceutically acceptable salts, isomers, or mixtures thereof, wherein 1 to n hydrogen atoms linked to a carbon atom may be replaced with deuterium atoms or D, where n is the number of hydrogen atoms in the molecule. As is known in the art, deuterium atoms are non-radioactive isotopes of hydrogen atoms. Such compounds can have increased resistance to metabolism and can therefore be used to extend the half-life of the compounds described herein or pharmaceutically acceptable salts, isomers, or mixtures thereof when administered to mammals.
[0057] See Foster, "Deuterium Isotope Effects in Studies of Drug Metabolism," Trends Pharmacol. Sci., 5(12):524-527 (1984), such compounds have been synthesized by methods well known in the art, for example, using starting materials in which one or more hydrogen atoms have been replaced with deuterium.

Isotopically labeled compounds of formula (IA-1) can be prepared by conventional techniques known to those skilled in the art, or by methods similar to those described in the Examples below, substituting appropriate isotopically labeled reagents for the previously used unlabeled reagents.
[0059] The compounds of the embodiments disclosed herein, or pharmaceutically acceptable salts thereof, may contain one or more asymmetric centers and may therefore give rise to enantiomeric, non-enantiomeric and other stereoisomeric forms, which may be defined according to their absolute stereochemistry as (R)- or (S)-, or, in the case of amino acids, as (D)- or (L)-.
[0060] This application is intended to include all these possible isomers and their racemic and optically pure forms. Optically active (+) and (-), (R) and (S), or (D) and (L)-isomers can be prepared by chiral syntheses or chiral reagents, or separated by conventional techniques such as chromatography and fractional crystallization.
[0061] Conventional techniques for preparing / separating single enantiomers include chiral synthesis from appropriate optically pure precursors or resolution of the racemate (or a racemate of a salt or derivative) using, for example, chiral high-pressure liquid chromatography (HPLC). Where the compounds described herein contain an ethylenic double bond or other center of geometric asymmetry, unless specified otherwise, such compounds are intended to include E and Z geometric isomers.
[0062] Similarly, all isomeric forms are included.
