BACKGROUND
The present disclosure relates, inter alia, to compositions and methods for treating viral diseases and cancer. In one aspect it relates to lipophilic antiviral and anticancer acyclic nucleoside phosphonate diesters, preparation thereof, and methods of using the compounds to treat viral diseases and cancer.
Viruses are infectious particles that can replicate their DNA and RNA only within host cells. Viral infections may lead to mild or severe illnesses in humans and mammals. Examples of viral infections include hepatitis B and C, smallpox, herpes simplex, cytomegalovirus, human immunodeficiency virus (HIV), influenza, adenovirus, chickenpox, BK virus, JC virus and precancerous lesions caused by infections with the human papillomavirus (cervical intraepithelial neoplasia, vaginal and anal intraepithelial neoplasia). Viral infection may also lead to cancer in humans and other species. Viruses known to cause cancer include but are not limited to human papilloma virus (HPV), hepatitis B virus (HBV), hepatitis C virus (HCV), HIV and Epstein Barr virus (EBV). Vaccination has been successful in preventing infection from many viruses. Antiviral agents are known that interfere with viral DNA or RNA synthesis and viral replication and are used to prevent or treat viral infections in mammals and humans. For example, combinations of antiviral drugs are used to treat AIDS, hepatitis B, hepatitis C, herpes simplex viruses, cytomegalovirus and influenza. Despite these successes, viral diseases remain an important public health problem and improved antiviral agents and anticancer agents are needed. For example, there is presently no approved antiviral treatment for human papillomavirus infections.
Many antiviral drugs are nucleoside or nucleotide analogs. Examples of antiviral nucleoside analogs include azidothymidine, acyclovir, ganciclovir, lamivudine and emtricitabine. Acyclic nucleoside phosphonates (ANPs) are a class of nucleotide analogs and are effective antiviral agents. Adefovir, tenofovir and cidofovir (CDV) are ANPs that have been approved for clinical use against human infections with HBV, HIV and CMV, respectively.
ANPs are known in the art not to be absorbed readily from the gastrointestinal tract of mammals because of their molecular weight and the presence of the double negative charge on the phosphonate. Because of their poor oral pharmacokinetic properties, ANPs are usually converted to prodrugs to produce clinically useful therapeutic agents. It has been demonstrated that masking one or both negative charges with promoieties improves the uptake and transport into the small intestinal enterocytes where the promoiety is cleaved, releasing the ANP into the circulation; examples include tenofovir disoproxil fumarate and adefovir dipivoxil. Another approach is to prepare alkoxyalkyl or alkyl monoesters of ANPs to increase oral bioavailability of the drug. With the alkoxyalkyl ANP monoester approach, side effects may occur when non-targeted tissues such as the small intestine are overexposed. For example, in enterocytes, enzymatic cleavage of the promoiety by a phospholipase C or an acid sphingomyelinase to the ANP may result in local toxicity because of further anabolic phosphorylation to the ANP diphosphate which may inhibit enterocyte DNA synthesis. Lipophilic ANP diester compounds are anticipated to undergo less cleavage from intact prodrug to ANP in the small intestine enterocytes following oral administration reducing GI side effects and releasing more drug substance into the circulation and producing higher levels of the drug substance in the blood.
ANPs or their alkyl or alkoxyalkyl monoesters may exhibit limited uptake in certain target tissues such as the central nervous system. An additional advantage of nucleoside phosphonate diesters is the masking of the remaining negative charge on the phosphonate oxygen with a second masking group which can increase penetration of the drug substance into the central nervous system (CNS) for treatment of CNS viral infections (for example, HIV or JC virus) or for treatment of brain cancers such as glioblastoma. Cancer cells rapidly synthesize DNA and undergo uncontrolled cell division. The lipophilic acyclic nucleoside phosphonate (ANP) diester compositions described herein can be metabolized to their diphosphates which inhibit or block DNA synthesis and cell division in target cancer cells, leading to cell death while having substantially lesser effects on non-malignant cells. Exposure of various types of cancer cells to acyclic nucleoside phosphonates diesters may result in much greater cytotoxicity than that observed in normal non-malignant cells. For example, leukemias, lymphomas, brain neoplasms such as glioblastoma and cervical cancer cells may be more susceptible to the cytotoxic effects when exposed to lipophilic ANP diesters than the corresponding non-malignant cell lines. Lipophilic acyclic nucleoside phosphonate diesters exhibit more selective toxicity, improved access to the central nervous system and effective topical uptake for treatment of skin cancers, viral skin infections, cervical intraepithelial neoplasia (CIN), vaginal and anal intraepithelial dysplasia, venereal warts and related infections caused by the human papillomavirus when compared to acyclic nucleoside phosphonate monoester compositions.
Compounds disclosed herein having both ANP phosphonate negative charges masked with functional groups provide for more effective use as topical agents for treatment of skin cancers and viral infections. In particular, compounds disclosed herein provide for efficacious treatment for infections of the cervical, vaginal, rectal and penile epithelium with the human papilloma virus including the high risk subtypes such as 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 73, and 82 which are associated with cervical, rectal, penile and vaginal cancer and venereal warts.

DETAILED DESCRIPTION
I. Definitions
The abbreviations used herein have their conventional meaning within the chemical and biological arts. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts.
Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., —CH2O— is equivalent to —OCH2—.
As used herein, the term “alkyl,” by itself or as part of another substituent, means, unless otherwise stated, and includes a straight (i.e., unbranched) or branched chain, or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include di- and multivalent radicals, having the number of carbon atoms designated (i.e., C1-C10 means one to ten carbons). Alkyl is an uncyclized chain. Examples of saturated hydrocarbon radicals include, but are not limited to, groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, t-butyl, isobutyl, sec-butyl, (cyclohexyl)methyl, homologs and isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and the like.
An unsaturated alkyl group is one having one or more double bonds (an “alkenyl group”) or triple bonds (an “alkynyl group”). Examples of unsaturated alkyl groups include, but are not limited to, the alkenyl groups vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(1,4-pentadienyl), and the alkynyl groups ethynyl, 1- and 3-propynyl, 3-butynyl, and the higher homologs and isomers.
An alkoxy is an alkyl attached to the remainder of the molecule via an oxygen linker (—O—).
The term “alkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkyl, as exemplified, but not limited by, —CH2CH2CH2CH2—. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, or 10 or fewer carbon atoms. A “lower alkyl” or “lower alkylene” is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms.
The term “heteroalkyl,” by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched chain, or combinations thereof, consisting of at least one carbon atom and at least one heteroatom selected from the group consisting of O, N, P, Si, and S, and wherein the nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. The heteroatom(s) O, N, P, S, and Si may be placed at any interior position of the heteroalkyl group or at the position at which the alkyl group is attached to the remainder of the molecule. Heteroalkyl is an uncyclized chain. Examples include, but are not limited to: —CH2—CH2—O—CH3, —CH2—CH2—NH—CH3, —CH2—CH2—N(CH3)—CH3, —CH2—S—CH2—CH3, —CH2—CH2, —S(O)—CH3, —CH2—CH2—S(O)2—CH3, —CH═CH—O—CH3, —Si(CH3)3, —CH2—CH═N—OCH3, —CH═CH—N(CH3)—CH3, —O—CH3, —O—CH2—CH3, and —CN. Up to two heteroatoms may be consecutive, such as, for example, —CH2—NH—OCH3.
Similarly, the term “heteroalkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from heteroalkyl, as exemplified, but not limited by, —CH2—CH2—S—CH2—CH2— and —CH2—S—CH2—CH2—NH—CH2—. For heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied by the direction in which the formula of the linking group is written. For example, the formula —C(O)2R— represents both —C(O)2R′— and —R′C(O)2—.
As described above, heteroalkyl groups, as used herein, include those groups that are attached to the remainder of the molecule through a heteroatom, such as —NR′R′′, —OR′, —SR′, and/or —SO2R′. Where “heteroalkyl” is recited, followed by recitations of specific heteroalkyl groups, such as —NR′R′′ or the like, it will be understood that the terms heteroalkyl and —NR′R′′ are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term “heteroalkyl” should not be interpreted herein as excluding specific heteroalkyl groups, such as —NR′R′′ or the like.
The terms “cycloalkyl” and “heterocycloalkyl,” by themselves or in combination with other terms, mean, unless otherwise stated, cyclic versions of “alkyl” and “heteroalkyl,” respectively. Cycloalkyl and heteroalkyl are not aromatic. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule. Examples of cycloalkyl include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, and the like. Examples of heterocycloalkyl include, but are not limited to, 1-(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-morpholinyl, 3-morpholinyl, tetrahydrofuran-2-yl, tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl, 1-piperazinyl, 2-piperazinyl, and the like.
A “cycloalkylene” and a “heterocycloalkylene,” alone or as part of another substituent, means a divalent radical derived from a cycloalkyl and heterocycloalkyl, respectively.
The terms “halo” or “halogen,” by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as “haloalkyl” are meant to include monohaloalkyl and polyhaloalkyl. For example, the term “halo(C1-C4)alkyl” includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.
The term “acyl” means, unless otherwise stated, —C(O)R* where R* is a substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl.
The term “aryl” means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent, which can be a single ring or multiple rings (preferably from 1 to 3 rings) that are fused together (i.e., a fused ring aryl) or linked covalently. A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring.
The term “heteroaryl” refers to aryl groups (or rings) that contain from one to four heteroatoms selected from N, O, and S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term “heteroaryl” includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. Likewise, a 6,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. And a 6,5-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 5 members, and wherein at least one ring is a heteroaryl ring. A heteroaryl group can be attached to the remainder of the molecule through a carbon or heteroatom. Non-limiting examples of aryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl. Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. An “arylene” and a “heteroarylene,” alone or as part of another substituent, mean a divalent radical derived from an aryl and heteroaryl, respectively.
For brevity, the term “aryl” when used in combination with other terms (e.g., aryloxy, arylthioxy, arylalkyl) includes both aryl and heteroaryl rings as defined above. Thus, the term “arylalkyl” [e.g., aryl(C1-6 alkyl)] is meant to include those radicals in which an aryl group is attached to an alkyl group (e.g., benzyl (Bn), phenethyl, pyridylmethyl, and the like) including those alkyl groups in which a carbon atom (e.g., a methylene group) has been replaced by, for example, an oxygen atom (e.g., phenoxymethyl, 2-pyridyloxymethyl, 3-(1-naphthyloxy)propyl, and the like). Thus, the term “heteroarylalkyl” [e.g., heteroaryl(C1-6 alkyl)] refers to those radicals in which a heteroaryl group is attached to an alkyl group. The term “heterocycloalkylalkyl” [e.g., heterocycloalkyl(C1-6 alkyl)] refers to those radicals in which a heterocycloalkyl is attached to an alkyl group.
The term “oxo,” as used herein, means an oxygen that is double bonded to a carbon atom.
The term “alkylsulfonyl,” as used herein, means a moiety having the formula —S(O2)—R′, where R′ is an alkyl group as defined above. R′ may have a specified number of carbons (e.g., “C1-C4 alkylsulfonyl”).
Each of the above terms (e.g., “alkyl,” “heteroalkyl,” “aryl,” and “heteroaryl”) includes both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below.
Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, —OR′, ═O, ═NR′, ═N—OR′, —NR′R′′, —SR′, -halogen, —SiR′R′′R′′′, —OC(O)R′, —C(O)R′, —CO2R′, —CONR′R′′, —OC(O)NR′R′′, —NR′′C(O)R′, —NR′—C(O)NR′′R′′′, —NR′′C(O)2R′, —NR—C(NR′R′′R′′′)═NR′′′′, —NR—C(NR′R′′)═NR′′′, —S(O)R′, —S(O)2R′, —S(O)2NR′R′′, —NRSO2R′, —CN, and —NO2 in a number ranging from zero to (2m′+1), where m′ is the total number of carbon atoms in such radical. R′, R′′, R′′′, and R′′′′ each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound includes more than one R group, for example, each of the R groups is independently selected as are each R′, R′′, R′′′, and R′′′′ group when more than one of these groups is present. When R′ and R′′ are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, —NR′R′′ includes, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term “substituted alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., —CF3 and —CH2CF3) and acyl (e.g., —C(O)CH3, —C(O)CF3, —C(O)CH2OCH3, and the like).
Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: —OR′, —NR′R′′, —SR′, -halogen, —SiR′R′′R′′′, —OC(O)R′, —C(O)R′, —CONR′R′′, —OC(O)NR′R′′, —NR′′C(O)R′, —NR—C(O)NR′′R′′′, —NR′′C(O)2R′, —NR—C(NR′R′′R′′′)═NR′′′, —NR—C(NR′R′′)═NR′′′, —S(O)R′, —S(O)2R′, —S(O)2NR′R′′, —NRSO2R′, —CN, —NO2, —R′, —N3, —CH(Ph)2, fluoro(C1-C4)alkoxy, and fluoro(C1-C4)alkyl, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R′, R′′, R′′′, and R′′′′ are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. When a compound includes more than one R group, for example, each of the R groups is independently selected as are each R′, R′′, R′′′, and R′′′′ groups when more than one of these groups is present.
Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In embodiments, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In another embodiment, the ring-forming substituents are attached to a single member of the base structure. For example, two ring-forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure.
Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally form a ring of the formula -T-C(O)—(CRR′)q—U—, wherein T and U are independently —NR—, —O—, —CRR′—, or a single bond, and q is an integer of from 0 to 3. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH2)r—B—, wherein A and B are independently —CRR′—, —O—, —NR—, —S—, —S(O)—, —S(O)2—, —S(O)2NR′—, or a single bond, and r is an integer of from 1 to 4. One of the single bonds of the new ring so formed may optionally be replaced with a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula —(CRR′)s—X′—(C′′R′′′)d—, where s and d are independently integers of from 0 to 3, and X′ is —O—, —NR′—, —S—, —S(O)—, —S(O)2—, or —S(O)2NR′—. The substituents R, R′, R′′, and R′′′ are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl.
As used herein, the terms “heteroatom” or “ring heteroatom” are meant to include oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and silicon (Si).
A “substituent group,” as used herein, means a group selected from the following moieties:

    
    
        (A)-OH, —NH2, —SH, —CN, —CF3, —NO2, oxo, halogen, unsubstituted alkyl, unsubstituted heteroalkyl, unsubstituted cycloalkyl, unsubstituted heterocycloalkyl, unsubstituted aryl, unsubstituted heteroaryl, and
        (B) alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl, and heteroaryl, substituted with at least one substituent selected from:

            (ii) alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl, and heteroaryl, substituted with at least one substituent selected from:

Exemplary viral diseases include human papilloma virus, HIV, hepatitis B virus, hepatitis C virus, variola virus (smallpox), vaccinia virus, adenovirus, cytomegalovirus (CMV), herpes simplex viruses, Epstein Barr virus, BK virus, JC virus, any double stranded DNA virus, feline leukemia virus, feline immunodeficiency virus, and the like. A therapeutically effective amount of a compound of Formula (I) can be administered to a human or mammal in need of treatment of a viral disease.
In embodiments, the compound is administered by a route (topical, intravitreal, oral, intravenous etc.) which results in delivery of an amount sufficient to inhibit replication of the virus. In embodiments, the compound can be administered topically. For example, the compound can be administered topically in the form of a cream, a gel or an ointment
In another aspect, there is provided a method for treating a disease or disorder in a subject in need thereof, the method including administering to a subject in need thereof a therapeutically effective amount of a compound with structure of any of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia). Aspects for the treatment of cancer and other neoplastic disorders contemplated herein are based on the surprising discovery that compounds of Formulae (I) and/or (Ia) are effective in killing or inhibiting growth of cells that are transformed by human papillomavirus (HPV), for example cervical cancer cells and cervical intraepithelial neoplasia (CIN) lesions. Accordingly, a therapeutically effective amount of a compound of Formula (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia) can be administered by an appropriate route (topical, orally, intravenous etc.) to kill or inhibit growth of infected/transformed cells. Cells that are transformed by other types of viruses, such as herpes simplex virus-2 (HSV-2), also may be treated with a compound of Formula (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia).
In another aspect, there is provided a method for treating cancer in a subject. The method includes administering to a subject in need thereof a therapeutically effective amount of a compound with the structure of any of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia). In embodiments, L/La of any of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia) is a lipophilic promoiety.
In embodiments, the cancer is leukemia, carcinoma and/or sarcoma, such as cancer of the brain, breast, cervix, colon, pancreas, head and neck, liver, kidney, lung, non-small cell lung, prostate, melanoma, mesothelioma, ovary, sarcoma, stomach, uterus and/or medulloblastoma. Additional examples include, Hodgkin's Disease, Non-Hodgkin's Lymphoma, multiple myeloma, neuroblastoma, ovarian cancer, rhabdomyosarcoma, primary thrombocytosis, primary macroglobulinemia, primary brain tumors, malignant pancreatic insulanoma, malignant carcinoid, urinary bladder cancer, premalignant skin lesions, testicular cancer, lymphomas, thyroid cancer, neuroblastoma, esophageal cancer, genitourinary tract cancer, malignant hypercalcemia, endometrial cancer, adrenal cortical cancer, and neoplasms of the endocrine and exocrine pancreas. In embodiments, the cancer is liver cancer, colon cancer, breast cancer, melanoma, acute myelogenous leukemia, chronic myelogenous leukemia, and/or non-small-cell lung cancer.
In another aspect, there is provided a method for treating a proliferative disorder in a subject. The method includes administering to a subject in need thereof a therapeutically effective amount of a compound with the structure of any of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia). The proliferative disorder may be caused by the human papilloma virus. Exemplary proliferative disorders include, e.g., cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), anal intraepithelial neoplasia (AlN), or penile and venereal warts. In embodiments, L/La of any of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia) is a lipophilic promoiety.
In another aspect, there is provided a method for killing or inhibiting the growth of a transformed cell. The method includes contacting a transformed cell with a therapeutically effective amount of a compound of any one of Formulae (I), (I-1), (I-2), (I-3), (I-4), (I-5) and/or (Ia).
In another aspect, there is provided a compound of Formula (Ia) or embodiment thereof, or a pharmaceutically acceptable salt, hydrate, solvate or crystalline form thereof, for use in treating a viral disease in a subject, wherein the viral disease can be selected from human papilloma virus (HPV), HIV, hepatitis B virus, hepatitis C virus, variola virus, vaccinia virus, an adenovirus, a cytomegalovirus, herpes simplex virus 1, herpes simplex virus 2, Epstein Barr virus, BK virus, JC virus, feline leukemia virus and feline immunodeficiency virus.
In embodiments, the virus can be human papilloma virus. According to the CDC, HPV is the most common sexually transmitted infection (STI). HPV viruses can be classified into mucosal and cutaneous HPVs. Within each of these groups, the individual viruses are designated high risk or low risk. More than 40 types of HPV's can infect the genital areas of women and men, and several HPV types can infect the mouth and throat. Additionally, HPV is the most common cause of cervical cancer.

V. Pharmaceutical Compositions
In another aspect, there is provided a pharmaceutical compositions including a compound of Formula (I) and/or a compound of Formula (Ia) in combination with a pharmaceutically acceptable excipient (e.g., carrier).
The terms “pharmaceutically acceptable carrier,” “pharmaceutically acceptable excipient” and the like as used herein refer to pharmaceutical excipients, for example, pharmaceutically, physiologically, acceptable organic or inorganic carrier substances suitable for enteral or parenteral application that do not deleteriously react with the active agent. Suitable pharmaceutically acceptable carriers include water, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, and carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, and polyvinyl pyrrolidine. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds described herein.
The compounds described herein can be administered alone or can be coadministered to the subject. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). The preparations can also be combined, when desired, with other active substances (e.g., to reduce metabolic degradation).
A. Formulations
The compounds described herein can be prepared and administered in a wide variety of oral, parenteral, and topical dosage forms. Thus, the compounds described herein can be administered by injection (e.g. intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally). Also, the compounds described herein can be administered by inhalation, for example, intranasally. Additionally, the compounds described herein can be administered transdermally. It is also envisioned that multiple routes of administration (e.g., intramuscular, oral, transdermal) can be used to administer the compounds described herein. Accordingly, pharmaceutical compositions comprising a pharmaceutically acceptable carrier or excipient and one or more compounds are contemplated.
For preparing pharmaceutical compositions, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances that may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.
In powders, the carrier is a finely divided solid in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.
The powders and tablets preferably contain from 5% to 70% of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.
For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.
When parenteral application is needed or desired, particularly suitable admixtures are injectable, sterile solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. In particular, carriers for parenteral administration include aqueous solutions of dextrose, cyclodextrins, saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, polyoxyethylene-block polymers, and the like. Ampoules are convenient unit dosages. The compounds described herein can also be incorporated into liposomes or administered via transdermal pumps or patches. Pharmaceutical admixtures suitable for use include those described, for example, in PHARMACEUTICAL SCIENCES (17th Ed., Mack Pub. Co., Easton, Pa.) and WO 96/05309, the teachings of both of which are hereby incorporated by reference.
Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizers, and/or thickening agents as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.
Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.
The pharmaceutical preparation is preferably in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form. In embodiments, the unit dosage form can be in the form of an applicator pre-filled with a pharmaceutical composition described herein (for example, a pharmaceutical composition that contains an effective amount of a compound of Formula (I) and/or a compound of Formula (Ia)). In embodiments, the pre-filled applicator can be filled with a pharmaceutical composition in the form of a cream, a gel or an ointment that contains a compound described herein (for example, a compound of Formula (I) and/or a compound of Formula (Ia)).
The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 10000 mg, more typically 1.0 mg to 1000 mg, most typically 10 mg to 500 mg, according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents.
Some compounds may have limited solubility in water and therefore may require a surfactant or other appropriate co-solvent in the composition. Such co-solvents include: Polysorbate 20, 60, and 80; Pluronic F-68, F-84, and P-103; cyclodextrin; and polyoxyl 35 castor oil. Such co-solvents are typically employed at a level between about 0.01% and about 2% by weight.
Viscosity greater than that of simple aqueous solutions may be desirable to decrease variability in dispensing the formulations, to decrease physical separation of components of a suspension or emulsion of formulation, and/or otherwise to improve the formulation. Such viscosity building agents include, for example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin sulfate and salts thereof, hyaluronic acid and salts thereof, and combinations of the foregoing. Such agents are typically employed at a level between about 0.01% and about 2% by weight.
The compositions may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides, and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes.
B. Effective Dosages
Pharmaceutical compositions include compositions wherein the active ingredient is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. For example, when administered in methods to treat cancer, such compositions will contain an amount of active ingredient effective to achieve the desired result (e.g., decreasing the number of cancer cells in a subject).
The dosage and frequency (single or multiple doses) of compound administered can vary depending upon a variety of factors, including route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated; presence of other diseases or other health-related problems; kind of concurrent treatment; and complications from any disease or treatment regimen. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds described herein.
For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Therapeutically effective amounts for use in humans may subsequently be estimated from animal models using conventional techniques that are confirmed or refined in actual clinical trials.
Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side effects. Generally, treatment is initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. In one embodiment, the dosage range is 0.001% to 10% w/v. In another embodiment, the dosage range is 0.1% to 5% w/v.
Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.
Utilizing the teachings provided herein, an effective prophylactic or therapeutic treatment regimen can be planned that does not cause substantial toxicity and yet is entirely effective to treat the clinical symptoms demonstrated by the particular patient. This planning should involve the careful choice of active compound by considering factors such as compound potency, relative bioavailability, patient body weight, presence and severity of adverse side effects, preferred mode of administration, and the toxicity profile of the selected agent.
C. Toxicity
The ratio between toxicity and therapeutic effect for a particular compound is its therapeutic index and can be expressed as the ratio between LD50 (the amount of compound lethal in 50% of the population) and ED50 (the amount of compound effective in 50% of the population). Compounds that exhibit high therapeutic indices are preferred. Therapeutic index data obtained from cell culture assays and/or animal studies can be used in formulating a range of dosages for use in humans. The dosage of such compounds preferably lies within a range of plasma concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. See, e.g. Fingl et al., In: THE PHARMACOLOGICAL BASIS OF THERAPEUTICS, Ch. 1, p. 1, 1975. The exact formulation, route of administration, and dosage can be chosen by the individual physician in view of the patient's condition and the particular method in which the compound is used.

Antiproliferative Activity of Nucleoside Phosphonates Diesters in Normal Human Fibroblasts and in Human Cervical Cancer Lines in Vitro
Method.
Compounds at a range of concentrations were incubated with normal fibroblasts or human cervical cancer cell lines in monolayer culture and after 4 days, viable cell number was determined by neutral red reduction as previously described (Valiaeva N, et al., Chemotherapy, 2010, 56(1):54-9). Cell lines were obtained from American Type Culture Collection. The results were plotted and the concentration which reduced neutral red levels by 50% (CC50) was determined in triplicate. Although viral replication is no longer occurring in the human cervical cancer cell lines, Caski cells were transformed by HPV-16 and Hela cells were transformed by HPV-18.
Results.
As tabulated in Table 11 following, these results demonstrate that compounds described herein were 23.6 fold (e.g., Cmpd 219) to 3,750 fold (e.g., Cmpd 1) more effective in reducing viable cell number in the cervical cancer lines than in normal, non-transformed human fibroblasts.

Anti-HIV Activity
Method HIV Antiviral Assays.
MT-2 cells were maintained in RPMI 1640 supplemented with 10% FBS, 10 mM HEPES buffer, 50 IU of penicillin/ml, and 50 μg of streptomycin/ml. The antiviral activity of each compound was determined by inoculating MT-2 cells with HIV-1LA1 at a multiplicity of infection (MOI) of 0.001 TCID50/cell, followed by incubation in the presence of threefold serial drug dilutions (three wells per dilution). Four days after infection, culture supernatants were harvested, lysed with 0.5% Triton X-100, and assayed for p24 antigen concentration using a commercial ELISA assay (Perkin Elmer Life Sciences, Boston, Mass.). The antiviral activity of each compound is expressed as the EC50, which is the concentration required to inhibit p24 antigen production by 50%.

Example 34
Antiviral Effect of ANP Diesters in HPV-18 Infected Primary Human Keratinocyte Rafts
Method.
Primary human keratinocytes (PHKs) were transfected with an HPV-18 genomic plasmid containing G418 resistance gene which was generated by Cre-loxP-mediated excision recombination. After a 4 day selection with G418, the surviving cells were cultured for 2-3 day and used to develop into raft cultures where the PHK cells stratify and differentiate into a squamous epithelium in 10 or more days. HPV-18 viral DNA usually amplifies between 10-14 days after the raft cultures are lifted to the air-medium interface. Efficacy and toxicity of the test compounds were determined at three concentrations added to the media from day 6 or 8 until day 14. Medium is changed every other day. Prior to harvest, BrdU is added to the medium at 100 μg/ml to document host cell DNA replication. One set of raft cultures (with or without test compounds) is harvested for quantitative real time PCR (qPCR) to determine the copy number of HPV-18 DNA/cell. Another set of the raft cultures are fixed in formalin, embedded in paraffin and toxicity is determined by histology. Additional sections are subjected to in situ hybridization to localize viral DNA amplification and BrdU incorporation which denotes host DNA replication in basal and suprabasal strata.

Antiviral Effect of ANP Diesters in HIV-192US727 Infected Human Peripheral Blood Monocytes
Method. Human peripheral blood monocyte (PBMC) based anti-HIV assays were performed as previously described (K. M. Watson, et al., 2008, Antimicrob Agents Chemother. 52:2787). Briefly, PHA-stimulated PBMCs cultured in the presence of IL-2 were suspended at 1×106 cells/mL and were added to a 96-well round-bottom plate. Serially diluted test materials were added to the plate in triplicate followed by the appropriate pre-titered strain of HIV. The culture was incubated for 7 days at 37° C./5% CO2. Following the incubation, supernatants were collected for analysis of virus replication by supernatant reverse transcriptase activity and cells analyzed for viability by tetrazolium dye XTT reduction (2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide). All the assays were carried out in triplicate. Microsoft Excel 2007 was used to analyze and graph data. The percent reduction in virus replication compared to the untreated virus controls was calculated for each compound. The percent cell control value was calculated for each compound comparing the drug treated uninfected cells to the uninfected cells in medium alone.

Example 37
Antiviral Effect of ANP Diesters on Hepatitis B Virus Replication in 2.2.15 Cells In Vitro
Method.
HBV antiviral assays (Korba & Gerin, Antivir. Res., 1992, 19:55 and Iyer, et al., Antivir Agents Chem. Chemother., 2004, 48:2199) are conducted using confluent cultures of 2.2.15 cells (genotype ayw; parental cell HepG2) maintained on 96-well flat-bottomed tissue culture plates. Confluence in this culture system is required for active, high levels of HBV replication equivalent to that observed in chronically-infected individuals (Sells, et al., J. Vivol., 1988, 62:2836; Korba & Gerin, Antivir. Res., 1992, 19:55). Cultures are treated for 7 days. HBV DNA levels in the culture medium (representing HBV virion production) are assessed by quantitative blot hybridization 24 hrs. after the last treatment. Cytotoxicity is assessed (A510) by uptake of neutral red dye 24 hr. following the last treatment. Lamivudine (LMV) is used as the standard assay control. EC50, EC90 and CC50 values are calculated by linear regression analysis (MS EXCEL®, QUATTROPRO®) using data combined from all treated cultures (Korba & Gerin, 1992, Id.; Okuse, et al., Antivir. Res., 2005, 65:23). Standard deviations for EC50 and EC90 values are calculated from the standard errors generated by the regression analyses. EC50 and EC90 are drug concentrations at which a 2-fold, or a 10-fold depression of HBV DNA (relative to the average levels in untreated cultures), respectively, is observed. CC50 is the drug concentration at which a 2-fold lower level of neutral red dye uptake (relative to the average levels in untreated cultures) is observed.
