[0001] 70504W001

[0002] FUSED TRICYCLIC HETEROCYCLES HAVING ACTIVITY AGAINST HIV INFECTION BACKGROUND OF THE INVENTION

[0003] Human immunodeficiency virus type 1 (HIV-1) infection leads to the contraction of acquired immune deficiency disease (AIDS). According to the Joint United Nations Programme on HIV / AIDS (UNAIDS), the number of cases of HIV continues to rise, and an estimated over thirty-nine million individuals worldwide suffer from HIV infection at the end of 2023.

[0004] Presently, long-term suppression of viral replication with antiretroviral drugs is the only option for treating HIV-1 infection. Almost all HIV positive patients are treated with therapeutic regimens of antiretroviral drug combinations termed, highly active antiretroviral therapy (" HAART"). The therapeutic medication period is quite long because people living with HIV have an average life expectancy closer to that of healthy people. These therapies must be administered often (daily) and regimented to prevent the emergence of drug resistant HIV-1 variants.

[0005] Another way to potentially address preventing formation of mutations is to increase patient adherence to a drug regimen. One manner that may be employed to accomplish this is by reducing the dosing frequency. For parenteral administration, it is believed to be advantageous to have drug substances with high lipophilicity or crystallinity in order to reduce solubility and limit the release rate within interstitial fluid. The development of therapeutic drugs with longer dosing intervals (e.g., Long-acting injections in which treatments can be dosed every 1, 2, 3, 6, or 12 months) is desired to reduce medication fatigue and improve patient quality of life.

[0115] heteroatom may contain different heteroatoms. "5- or 6- membered heterocycloalkyl" refers to a saturated or unsaturated 5- or 6-membered monocyclic ring, which must contain 1 or 2 non-carbon atoms, which are selected from nitrogen, oxygen, and sulfur. Exemplary groups include, but are not limited to, pyrrolidinyl, pyrazolidinyl, pyrazolinyl, imidazolidinyl, imidazolinyl, oxazolinyl, thiazolinyl, piperidinyl, piperazinyl, tetrahydrofuranyl, di hydrofuranyl, 1,3-dioxolanyl, tetrahydro-2H-pyranyl, dihydropyranyl, morpholinyl, morpholinyl-3-one, 1,3-dioxanyl, 1,4-dioxanyl, 1,3-oxathiolanyl, 1,3-oxathianyl, 1,3-dithianyl, 1,4-oxathiolanyl, 1,4-oxathianyl, 1,4-dithianyl, piperidyl-2-one, pyrimidinyl-2, 4(11-1, 3H)-dione, thiomorpholinyl, and thiomorpholinyl 1,1-dioxide.

[0116] The term "aryl" refers to a monocyclic or bicyclic, hydrocarbon, aromatic radical. Aryl includes, for example, phenyl, naphthyl, indenyl, and dihydroindenyl. An aryl group may contain 6 to 14 carbon atoms.

[0117] The term "heteroaryl" refers to a group or moiety comprising an aromatic monovalent monocyclic or bicyclic radical, containing 5 to 10 ring atoms, including at least one (e.g., one, two, three, or four) heteroatom independently selected from nitrogen, oxygen and sulfur. This term also encompasses bicyclic heterocyclic-aryl compounds containing an aryl ring moiety fused to a heterocycloalkyl ring moiety, containing 5 to 10 ring atoms, including at least one heteroatom independently selected from nitrogen, oxygen and sulfur. Exemplary groups include, but are not limited to furanyl, thienyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, thiazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiadiazolyl, isothiazolyl, pyridyl, pyridazinyl, pyrazinyl, pyrimidinyl, triazinyl, benzofuranyl, isobenzofuryl, 2,3-dihydrobenzofuryl, 1,3-benzodioxolyl, dihydrobenzodioxinyl, benzothienyl, indolizinyl, indolyl, isoindolyl, dihydroindolyl, benzimidazolyl, dihydrobenzimidazolyl, benzoxazolyl, dihydrobenzoxazolyl, benzthiazolyl, benzoisothiazolyl, dihydrobenzoisothiazolyl, indazolyl, imidazopyridinyl, pyrazolopyridyl, benzotriazolyl, triazolopyridyl, purinyl, quinolinyl, tetrahydroquinolinyl, isoquinolinyl, tetrahydroisoquinolinyl, quinoxalinyl, cinnolinyl, phthalazinyl, quinazolinyl, 1,5-naphthyridinyl, 1,6-naphthyridinyl, 1,7-naphthyridinyl, 1,8-naphthyridinyl, and pteridinyl.

Examples of 6-membered "heteroaryl" groups include oxo-pyridyl, pyridyl, pyridazinyl, pyrazinyl, and pyrimidinyl. Examples of 6,6-fused "heteroaryl" groups include quinolinyl, isoquinolinyl, quinoxalinyl, cinnolinyl, phthalazinyl, quinazolinyl, 1,5-naphthyridinyl, 1,6-naphthyridinyl, 1,7-naphthyridinyl, 1,8-naphthyridinyl, and pteridinyl. Examples of 6,5-fused "heteroaryl" groups include benzofuranyl, benzothienyl, benzimidazolyl, benzthiazolyl, indolizinyl, indolyl, isoindolyl, and indazolyl.

[0118] For the avoidance of doubt, all bicyclic ring systems may be attached at any suitable position on either ring. 70504W001

[0119] The terms "halogen" and "halo" represent chloro, fluoro, bromo, or iodo substituents.

[0120] The term "oxo" represents a double-bonded oxygen moiety; for example, if attached directly to a carbon atom forms a carbonyl moiety (C = O).

[0121] The term "optionally substituted" indicates that a group may be unsubstituted or substituted with one or more substituents as defined herein. The term "substituted" in reference to a group indicates that a hydrogen atom attached to a member atom within a group is replaced by one of the defined substituents. In the case where groups may be selected from a number of alternative groups, the selected groups may be the same or different.

[0122] The term "independently selected" means that where more than one substituent is selected from a number of possible substituents, those substituents may be the same or different. Thus, each substituent is separately selected from the entire group of recited possible substituents.

[0123] The term "member atoms" refers to the atom or atoms that form a chain or ring. Where more than one member atom is present in a chain and within a ring, each member atom is covalently bound to an adjacent member atom in the chain or ring. Atoms that make up a substituent group attached to a chain or ring are not member atoms in the chain or ring.

[0124] The term "pharmaceutically acceptable excipient" refers to an excipient for administration of a pharmaceutical agent, such as the compounds described herein. The term refers to any pharmaceutical excipient that may be administered without undue toxicity.

[0125] The term "pharmaceutically acceptable salts" refers to those compounds, materials, compositions, and dosage forms, which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings or animals without excessive toxicity, irritation, or other problem or complication. The skilled artisan will appreciate that pharmaceutically acceptable salts of compounds according to the invention may be prepared in situ during the final isolation and purification of the compound, or by separately reacting the purified compound in its free acid or free base form with a suitable base or acid, respectively.

[1254] An X-ray powder diffraction (XRPD) pattern will be understood to comprise a diffraction angle (expressed in degrees 20) of "about" a value specified herein when the XRPD pattern comprises a diffraction angle within ± 0.2 degrees 20 of the specified value. Further, it is well known and understood to those skilled in the art that the apparatus employed, humidity, temperature, orientation of the powder crystals, and other parameters involved in obtaining an XRPD pattern may cause some variability in the appearance, intensities, and positions of the lines in the diffraction pattern. An XRPD pattern that is "substantially in accordance" with that of a Figure provided herein is an XRPD pattern that would be considered by one skilled in the art to represent a compound possessing the same crystal form as the compound that provided the XRPD pattern of the Figure. That is, the XRPD pattern may be identical to that of the Figure or more likely it may be somewhat different. Such an XRPD pattern may not necessarily show each of the lines of the diffraction pattern presented herein, and / or may show a slight change in appearance, intensity, or a shift in position of said lines resulting from differences in the conditions involved in obtaining the data. A person skilled in the art is capable of determining if a sample of a crystalline compound has the same form as, or a different form from, the form disclosed herein by comparison of their XRPD patterns. For example, one skilled in the art can overlay an XRPD pattern of a sample of a different form of the specific compound, with the figure and, using expertise and knowledge in the art, readily determine whether the XRPD pattern of the sample is substantially in accordance with the XRPD pattern. If the XRPD pattern is substantially in accordance with the figure, the sample form can be readily and accurately identified as being the same form of the specific compound.

[1517] Certain compounds of the present invention are prodrugs of the parent compound, Compound A,

[1518]

[1519] (Compound A).

[1520] Parent Compound A is also known as (15,3aS)-N-(3-chloro-2-fluorobenzyl)-6-hydroxy-l-(methoxymethyl)-4-methyl-5,7-dioxo-2,3,3a,4,5,7-hexahydro-lH-pyrido[2,l-f]pyrrolo[l,2-b][l,2,4]triazine-8-carboxamide.

WO2019230858A1 provides integrase inhibitors for use in treating or preventing HIV. Integrase inhibitors (integrase strand transfer inhibitors (INSTIs)) are a class of antiretroviral drug designed to 70504W001

[1521] block the action of integrase (e.g., HIV integrase), a viral enzyme that inserts the viral genome into the DNA of the host cell.

[1522] Certain compounds of the present invention advantageously extend the half-life of parent Compound A, which in the field of HIV will benefit people who have to receive daily high doses or even several doses a day.

[1523] In the field of long-acting injectables, it is advantageous for the administered compound to be less soluble than the parent compound (Compound A). For parenteral administration, it is believed to be advantageous to have drug substances with high lipophilicity or crystallinity in order to reduce solubility and limit the release rate within interstitial fluid. Prodrugs offer the ability to form unique crystalline formations that enhance insolubility profiles to allow for therapeutic drug release rates that are amenable to injectable dosing intervals every 1, 2, 3, 4, 5, 6, or 12 months.
