BACKGROUND OF THE INVENTION
The disclosure generally relates to the novel compounds of formula I, including their salts, which inhibit HIV integrase and prevent viral integration into human DNA. This action makes the compounds useful for treating HIV infection and AIDS. The invention also encompasses pharmaceutical compositions and methods for treating those infected with HIV.
Human immunodeficiency virus (HIV) has been identified as the etiological agent responsible for acquired immune deficiency syndrome (AIDS), a fatal disease characterized by destruction of the immune system and the inability to fight off life threatening opportunistic infections. Recent statistics (UNAIDS: Report on the Global HIV/AIDS Epidemic, December 1998), indicate that as many as 33 million people worldwide are infected with the virus. In addition to the large number of individuals already infected, the virus continues to spread. Estimates from 1998 point to close to 6 million new infections in that year alone. In the same year there were approximately 2.5 million deaths associated with HIV and AIDS.
There are currently a number of antiviral drugs available to combat the infection. These drugs can be divided into four classes based on the viral protein they target and their mode of action. In particular, saquinavir, indinavir, ritonavir, nelfinavir atazanavir darunavir, amprenavir, fosamprenavir, lopinavir and tipranavir are competitive inhibitors of the aspartyl protease expressed by HIV. Zidovudine, didanosine, stavudine, lamivudine, zalcitabine, emtricitibine, tenofovir and abacavir are nucleoside reverse transcriptase inhibitors that behave as substrate mimics to halt viral cDNA synthesis. The non-nucleoside reverse transcriptase inhibitors, nevirapine, delavirdine, efavirenz and etravirine inhibit the synthesis of viral cDNA via a non-competitive (or uncompetitive) mechanism. Enfuvirtide and maraviroc inhibit the entry of the virus into the host cell. Used alone these drugs are effective in reducing viral replication. There are also peptidomimetic protease inhibitors including saquinavir, indinavir, ritonavir, nelfinavir, amprenavir, lopinavir, darunavir, atazanavir, and tipranavir, and integrase inhibitors such as raltegravir. The effect is only temporary as the virus readily develops resistance to all known agents. However, combination therapy has proven very effective at both reducing virus and suppressing the emergence of resistance in a number of patients. In the US, where combination therapy is widely available, the number of HIV-related deaths has declined (Palella, F. J.; Delany, K. M.; Moorman, A. C.; Loveless, M. O.; Further, J.; Satten, G. A.; Aschman, D. J.; Holmberg, S. D. N. Engl. J. Med. 1998, 338, 853-860).
Unfortunately, not all patients are responsive and a large number fail this therapy. In fact, approximately 30-50% of patients ultimately fail combination therapy. Treatment failure in most cases is caused by the emergence of viral resistance. Viral resistance in turn is caused by the rapid turnover of HIV-1 during the course of infection combined with a high viral mutation rate. Under these circumstances incomplete viral suppression caused by insufficient drug potency, poor compliance to the complicated drug regiment as well as intrinsic pharmacological barriers to exposure provides fertile ground for resistance to emerge. More disturbing are recent findings which suggest that low-level replication continues even when viral plasma levels have dropped below detectable levels (<50 copies/ml) (Carpenter, C. C.; Cooper, D. A.; Fischl, M. A.; Gatell, J. M.; Gazzard, B. G.; Hammer, S. M.; Hirsch, M. S.; Jacobsen, D. M.; Katzenstein, D. A.; Montaner, J. S.; Richman, D. D.; Saag, M. S.; Schechter, M.; Schooley, R. T.; Thompson, M. A.; Vella, S.; Yeni, P. G.; Volberding, P. A. JAMA 2000, 283, 381-390). Clearly, there is a need for new antiviral agents, preferably targeting other viral enzymes to reduce the rate of resistance and suppress viral replication even further.
HIV expresses three enzymes, reverse transcriptase, an aspartyl protease, and integrase. All three are targets for treating AIDS and HIV infection. HIV integrase is a component of the pre-integration complex of the virus that is assembled in the cell shortly after infection (Chiu, T. K.; Davies, D. R. Curr. Top. Med. Chem. 2004, 4, 965-977). This enzyme catalyzes the integration of proviral DNA into the host genome and is absolutely required for viral infectivity. Early experiments showed that mutating the active site of integrase within a proviral clone produces virus unable to replicate due to its inability to insert into the host chromosome (Englund, G.; Theodore, T. S.; Freed, E. O.; Engleman, A.; Martin, M. A. J. Virol. 1995, 69, 3216-3219). Selective HIV integrase inhibitors have been shown to possess effective anti-HIV activity in cell culture (Hazuda, D. J.; Felock, P.; Witmer, M.; Wolfe, A; Stillmock, K.; Grobler, J. A.; Espeseth, A.; Gabryelski, L.; Schleif, W.; Blau, C.; Miller, M. D. Science, 2000, 287, 646-650), and it is clear that this class of inhibitors is very effective as part of a combination regimen containing HIV inhibitors of different classes. An HIV integrase inhibitor, raltegravir (Isentress®), has been approved for use in treatment experienced patients based upon 48 week trial results (Cooper, D. A.; Gatell, J.; Rockstroh, J.; Katlama, C.; Yeni, P.; Lazzarin, A.; Xu, X.; Isaacs, R.; Teppler, H.; Nguyen, B. Y. 15th Conference on Retroviruses and Opportunistic Infections, Boston, Mass., Feb. 3-6, 2008 Abst. 105LB: Evering, T. H.; Markowitz, M. Drugs Today, 2007, 43, 865-877). In addition, a second integrase inhibitor, elvitegravir (GS-9137), completed a successful Phase II trial in combination with ritonavir boosting in naive and treatment experienced patients (Zolopa, A. 14th Conference on Retroviruses and Opportunistic Infections, Los Angeles, Calif. Feb. 25-28, 2007 Abst. 143LB). Thus, HIV-1 integrase is a promising target for novel anti-HIV-1 therapeutics.
HIV integrase inhibitors have been disclosed. See, for example, PCT patent application publications WO05/061501 and WO2010/088167.
The invention provides technical advantages, for example, the compounds are novel and inhibit HIV integrase. Additionally, the compounds provide advantages for pharmaceutical uses, for example, with regard to one or more of their mechanism of action, binding, inhibition efficacy, target selectivity, solubility, safety profiles, or bioavailability.

As such, the invention includes combinations of the different aspects.
Unless specified otherwise, these terms have the following meanings. “Halo” means fluoro, chloro, bromo, or iodo. “Alkyl” means a straight or branched alkyl group composed of 1 to 6 carbons. “Alkenyl” means a straight or branched alkyl group composed of 2 to 6 carbons with at least one double bond. “Cycloalkyl” means a monocyclic ring system composed of 3 to 7 carbons. “Hydroxyalkyl,” “alkoxy” and other terms with a substituted alkyl moiety include straight and branched isomers composed of 1 to 6 carbon atoms for the alkyl moiety. “Halo” includes all halogenated isomers from monohalo substituted to perhalo substituted in substituents defined with halo, for example, “Haloalkyl” and “haloalkoxy”, “halophenyl”, “halophenoxy.” “Aryl” means a monocyclic or bicyclic aromatic hydrocarbon groups having 6 to 12 carbon atoms, or a bicyclic fused ring system wherein one or both of the rings is a phenyl group. Bicyclic fused ring systems consist of a phenyl group fused to a four- to six-membered aromatic or non-aromatic carbocyclic ring. Representative examples of aryl groups include, but are not limited to, indanyl, indenyl, naphthyl, phenyl, and tetrahydronaphthyl. “Heteroaryl” means a 5 to 7 membered monocyclic or 8 to 11 membered bicyclic aromatic ring system with 1-5 heteroatoms independently selected from nitrogen, oxygen, and sulfur. Parenthetic and multiparenthetic terms are intended to clarify bonding relationships to those skilled in the art. For example, a term such as ((R)alkyl) means an alkyl substituent further substituted with the substituent R. Substituents which are illustrated by chemical drawing to bond at variable positions on a multiple ring system (for example a bicyclic ring system) are intended to bond to the ring where they are drawn to append. For example, substituents R1 and R2 of formula IV are intended to bond to the benzene ring of formula IV and not to the thiophene ring.
“Imidazolothionyl” means

Biological Methods
HIV-Integrase Inhibition Activity.
Radiolabeled integrase inhibitor, N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-2-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-2-yl)-4-pyrimidinecarboxamide, was used as a known reference ligand to determine the binding constants towards the integrase enzyme of the compounds described in this invention using a method similar to that described in; Dicker et al. J. Biological Chem. 2007, 282, 31186-31196; Dicker et al. J. Biol. Chem. 2008, 283, 23599-23609 and Dicker et al. Biochemistry 2008, 47, 13481-13488. N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-2-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-2-yl)-4-pyrimidinecarboxamide is a known active-site binding inhibitor as it can be competed off the. Kd values for [3H]N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-2-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-2-yl)-4-pyrimidinecarboxamide were determined from fitting data to a saturation binding curve using Graphpad Prism, V4.01. The Ki measurement toward integrase was made by measuring the inhibition of binding of [3H]N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-2-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-2-yl)-4-pyrimidinecarboxamide to enzyme-SPA bead complexes in the presence of serial dilutions of the test compounds. The Ki value was determined from the [3H]N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-2-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-2-yl)-4-pyrimidinecarboxamide Kd and the inhibition binding curve using Graphpad Prism, V4.03. Results are shown in the Table 1.

Inhibition of HIV Replication.
A recombinant NL-Rluc virus was constructed in which a section of the nef gene from NL4-3 was replaced with the Renilla Luciferase gene. The NL-RLuc virus was prepared by co-transfection of two plasmids, pNLRLuc and pVSVenv. The pNLRLuc contains the NL-Rluc DNA cloned into pUC18 at the PvuII site, while the pVSVenv contains the gene for VSV G protein linked to an LTR promoter. Transfections were performed at a 1:3 ratio of pNLRLuc to pVSVenv on 293T cells using the LipofectAMINE PLUS kit from Invitrogen (Carlsbad, Calif.) according to manufactures instruction, and the pseudotype virus generated was titered in MT-2 cells.
Susceptibility of viruses to compounds was determined by incubation in the presence of serial dilutions of the compound. The 50% effective concentration (EC50) was calculated by using the exponential form of the median effect equation where (Fa)=1/[1+(ED50/drug conc.)m] (Johnson V A, Byington R T. Infectivity Assay. In Techniques in HIV Research. ed. Aldovini A, Walker B D. 71-76. New York: Stockton Press. 1990). The anti-viral activity of compounds was evaluated under three serum conditions, 10% FBS, 15 mg/ml human serum albumin/10% FBS or 40% human serum/5% FBS, and the results from at least 2 experiments were used to calculate the EC50 values. Results are shown in the Table 2. Activity equal to A refers to a compound having IC50=<10 nM while B and C denote compounds having IC50=<10 nM and IC50<100 nM and IC50>100 nM respectively.

“Combination,” “coadministration,” “concurrent,” and similar terms referring to the administration of a compound of Formula I with at least one anti-HIV agent mean that the components are part of a combination antiretroviral therapy or highly active antiretroviral therapy (HAART) as understood by practitioners in the field of AIDS and HIV infection.
“Therapeutically effective” means the amount of agent required to provide a meaningful patient benefit as understood by practitioners in the field of AIDS and HIV infection. In general, the goals of treatment are suppression of viral load, restoration and preservation of immunologic function, improved quality of life, and reduction of HIV-related morbidity and mortality.
“Patient” means a person infected with the HIV virus and suitable for therapy as understood by practitioners in the field of AIDS and HIV infection.
“Treatment,” “therapy,” “regimen,” “HIV infection,” “ARC,” “AIDS” and related terms are used as understood by practitioners in the field of AIDS and HIV infection.
The compounds of this invention are generally given as pharmaceutical compositions comprised of a therapeutically effective amount of a compound of Formula I or its pharmaceutically acceptable salt and a pharmaceutically acceptable carrier and may contain conventional excipients. A therapeutically effective amount is that which is needed to provide a meaningful patient benefit. Pharmaceutically acceptable carriers are those conventionally known carriers having acceptable safety profiles. Compositions encompass all common solid and liquid forms including capsules, tablets, losenges, and powders as well as liquid suspensions, syrups, elixers, and solutions. Compositions are made using common formulation techniques, and conventional excipients (such as binding and wetting agents) and vehicles (such as water and alcohols) are generally used for compositions. See, for example, Remington's Pharmaceutical Sciences, 17th edition, Mack Publishing Company, Easton, Pa. (1985).
Solid compositions are normally formulated in dosage units and compositions providing from about 1 to 1000 mg of the active ingredient per dose are preferred. Some examples of dosages are 1 mg, 10 mg, 100 mg, 250 mg, 500 mg, and 1000 mg. Generally, other antiretroviral agents will be present in a unit range similar to agents of that class used clinically. Typically, this is 0.25-1000 mg/unit.
Liquid compositions are usually in dosage unit ranges. Generally, the liquid composition will be in a unit dosage range of 1-100 mg/mL. Some examples of dosages are 1 mg/mL, 10 mg/mL, 25 mg/mL, 50 mg/mL, and 100 mg/mL. Generally, other antiretroviral agents will be present in a unit range similar to agents of that class used clinically. Typically, this is 1-100 mg/mL.
The invention encompasses all conventional modes of administration; oral and parenteral methods are preferred. Generally, the dosing regimen will be similar to other antiretroviral agents used clinically. Typically, the daily dose will be 1-100 mg/kg body weight daily. Generally, more compound is required orally and less parenterally. The specific dosing regime, however, will be determined by a physician using sound medical judgement.
The invention also encompasses methods where the compound is given in combination therapy. That is, the compound can be used in conjunction with, but separately from, other agents useful in treating AIDS and HIV infection. Some of these agents include HIV attachment inhibitors, CCRS inhibitors, CXCR4 inhibitors, HIV cell fusion inhibitors, HIV integrase inhibitors, HIV nucleoside reverse transcriptase inhibitors, HIV non-nucleoside reverse transcriptase inhibitors, HIV protease inhibitors, budding and maturation inhibitors, immunomodulators, and anti-infectives. In these combination methods, the compound of Formula I will generally be given in a daily dose of 1-100 mg/kg body weight daily in conjunction with other agents. The other agents generally will be given in the amounts used therapeutically.
The specific dosing regime, however, will be determined by a physician using sound medical judgement. A partial list of such agents is shown in the table below.

Triethyl 4-hydroxycyclohex-3-ene-1,1,3-tricarboxylate
The title compound was prepared from diethyl malonate and ethyl acrylate using a procedure similar to that described in J. Org. Chem., 2007, 72, 7455. A solution of diethyl malonate (64 g, 400 mmol), and ethyl acrylate (88 g, 879 mmol) in THF (300 mL) in a 2 L 3-neck round bottom flask, equipped with a thermometer, a mechanical stirrer, a N2 inlet, and a condenser was cooled in a cold water bath ( ̃10° C.). 500 mL of a 1M THF solution of potassium tert-butoxide measured out for addition to the reaction. The reaction was initiated by very slowly introducing 2-5 mL of this solution to the reaction mixture (exothermic reaction) in order to maintain an internal temperature below 35° C. After the initial vigorous reaction subsided, the remainder of the solution was added drop-wise without a cooling bath over 1.5 h. During this period, the internal temp. remained between 20-28° C. The resulting cloudy amber solution was stirred at room temp. under N2 for 2.5 h, by which time a mass of precipitate had formed. The mixture was diluted with EtOAc (300 mL) and sat'd NH4Cl (200 mL), and then neutralized by the addition of 3N HCl (170 mL). The organic phase was washed with brine (100 mL), dried (Na2SO4), filtered and concentrated to give the title compound (135.2 g, 400 mmol, 100% yield) as an amber oil. HPLC: retention time=3.00 min (AP 81% at λ, =220 nm). LCMS: m/z 315 (M+H). 1H NMR (500 MHz, CDCl3) δ ppm 1.22 (6H, t, J=7.2 Hz, 12,15-CH3), 1.28 (3H, t, J=7.2 Hz, 9-CH3), 2.17 (2H, t, J=6.6 Hz, 5-CH2), 2.34 (2H, t, J=6.4 Hz, 6-CH2), 2.76 (2H, s, 3-CH2), 4.12-4.23 (6H, m, 8,11,14-OCH2), 12.2 (1H, s, 1-OH). 13C NMR (126 MHz, CDCl3) δ ppm 14.1 (12,15-CH3), 14.3 (9-CH3), 26.1 (6-CH2), 26.7 (5-CH2), 27.9 (3-CH2), 53.0 (4-C), 60.6 (8-OCH2), 61.6 (11,14-OCH2), 95.3 (2-C═), 170.2 (1-OC═), 170.8 (10,13-OC═O), 172.0 (7-OC═O).

Diethyl 4-oxocyclohexane-1,1-dicarboxylate
The procedure in Sanchez et al., Synth. Comm., 1985, 15, 141 was followed. A mixture of triethyl 4-oxocyclohexane-1,1,3-tricarboxylate, Intermediate 1, (135.2 g, 400 mmol), sodium chloride (70.1 g, 1200 mmol), and H2O (17.30 mL, 960 mmol) in DMSO (530 mL) was stirred at 160° C. (oil bath) under N2 for 3.5 h. The cooled mixture was poured into ice-water (3 L) and extracted with EtOAc (400 mL×3). The combined extracts were washed with brine, dried (Na2SO4) then concentrated to provide the title compound (103.4 g, 397 mmol, 99% yield) as an amber oil. HPLC: 2.04 min (AP 45% at 220 nm). LCMS: m/z 243 (M+H). 1H NMR (500 MHz, CDCl3) δ ppm 1.27 (6H, t, J=7.0 Hz, 9,12-CH3), 2.37 (4H, t, J=6.9 Hz, 3,5-CH2), 2.43 (4H, t, J=6.7 Hz, 2,6-CH2), 4.23 (4H, q, J=7.2 Hz, 8,11-OCH2). 13C NMR (126 MHz, CDCl3) δ ppm 14.1 (9,12-CH3), 31.0 (3,5-CH2), 37.8 (2,6-CH2), 53.6 (4-C), 61.9 (8,11-OCH2), 170.7 (7,10-OC═O), 209.4 (1-C═O).




Diethyl 1,4-dioxaspiro[4.5]decane-8,8-dicarboxylate
The procedure described in Pearson at al., J. Org. Chem., 1997, 62, 5284 was followed with a minor modification. A mixture of diethyl 4-oxocyclohexane-1,1-dicarboxylate, Intermediate 2, (120.6 g, 463 mmol), ethane-1,2-diol (110 mL, 1973 mmol), and para-toluene sulfonic acid mono hydrate (1.0 g, 5.26 mmol) in Benzene (250 mL) was stirred at room temp under N2 for 2 days. The mixture was diluted with Et2O (1 L) and washed with water (300 mL×3), sat'd NaHCO3 (100 mL) and then with brine, dried (MgSO4), and concentrated to dryness to provide the title compound (132.7 g, 463 mmol, 100% yield) as an amber oil HPLC: 2.38 min (AP 70% at 220 nm). LCMS: m/z 287 (M+H). 1H NMR (500 MHz, CDCl3) δ ppm 1.17 (6H, t, J=7.2 Hz, 9,12-CH3), 1.60 (4H, t, J=6.4 Hz, 2,6-CH2), 2.09 (4H, t, J=6.4 Hz, 3,5-CH2), 3.86 (4H, s, 13,14-OCH2), 4.11 (4H, q, J=7.2 Hz, 8,11-OCH2). 13C NMR (126 MHz, CDCl3) δ ppm 14.1 (9,12-CH3), 29.0 (3,5-CH2), 31.6 (2,6-CH2), 53.9 (4-C), 61.3 (8,11-OCH2), 64.3 (13,14-OCH2), 107.7 (1-OCO), 171.2 (7,10-OC═O).




1,4-Dioxaspiro[4.5]decane-8,8-diyldimethanol
A 3-neck 1-L round bottom flask was equipped with a thermometer, dropping funnel and nitrogen inlet. Under an atmosphere of N2, a solution of 1M lithium aluminum hydride in THF (900 mL, 900 mmol) was added and cooled using a dry ice/acetone bath. To this was added drop-wise a solution of diethyl 1,4-dioxaspiro[4.5]decane-8,8-dicarboxylate, Intermediate 3, (128.7 g, 450 mmol) in THF (75 mL) over a period of 1 h while maintaining the internal temperature at 10-15° C. The mixture was left in the cooling bath and allowed to regain room temperature while stirring overnight. The mixture was then cooled to −5° C. and quenched by the slow addition of water (40 mL) under vigorous stirring over 1.5 hours being careful to maintain the internal temperature below 30° C. To this was added drop-wise 15% NaOH (40 mL) and water (40 mL). The resulting precipitate was filtered over Celite, and washed with THF (300 mL). The filtrate was concentrated in vacuo to dryness to provide the title compound (63.3 g) as a white solid. Further extraction of the white cake with 10% MeOH/CH2Cl2 (2×500 mL) gave an additional amount (15.6 g) of the title compound. This constitutes total combined yield of 78.9 g (0.39 mol, Y. 87%). LCMS: m/z 203 (M+H), 225 (M+Na). 1HNMR (500 MHz, CD3OD) δ ppm 1.49-1.55 (4H, m, 3,5-CH2), 1.59-1.66 (4H, m, 2,6-CH2), 3.49 (4H, s, 9,10-OCH2), 3.94 (4H, s, 7,8-OCH2). 13C NMR (126 MHz, CD3OD) δ ppm 26.7 (3,5-CH2), 30.3 (2,6-CH2), 38.3 (4-C), 64.2 (7,8-OCH2), 65.4 (9,10-OCH2), 109.2 (1-OCO).
An alternative route to diethyl 4-oxocyclohexane-1,1-dicarboxylate, Intermediate 2, is described in the following:




1,5-Di-tert-butyl 3,3-diethyl pentane-1,3,3,5-tetracarboxylate
(Oosterbaan, W. D., Koper, C., Braam, T. W., Hoogesteger, F. J., Piet, J. J., Jansen, B. A. J., van Walree, C. A., van Ramesdonk, H. J., Goes, M., Verhoeven, J. W., Schuddeboom, W., Warman, J. M., Jenneskens, L. W., J. Phys. Chem. A., 2003, 107 (19), 3612, Supporting Information.)
