Description
FIELD OF THE INVENTION
[0001] The invention relates to novel substituted azole dione compounds having anti-cancer activity and/or activity against proliferating cells, and to methods of making and using these compounds, wherein the substituted azole dione compounds abrogate the cell cycle G2 checkpoint and/or cause adaptation to cell cycle arrest. The invention includes substituted azole dione compounds for use in methods to selectively suppress or kill cancer cells, with or without additional anti-cancer treatment. The invention includes cell cycle G2-checkpoint-abrogating substituted azole dione compounds provided herein for use in methods to selectively sensitize cancer cells to DNA damaging agents, DNA-damaging treatments and/or other types of anti-cancer agents.
BACKGROUND
[0002] The cell cycle comprises S phase (DNA replication), M phase (mitosis), and two gap phases (G1 and G2 phases) between S and M phases. Checkpoints in the cell cycle ensure accurate progression through cell cycle stages, and include monitoring DNA integrity, DNA replication, cell size, and the surrounding environment (Mailer (1991) Curr. Opin. Cell Biol., 3:26). Cell cycle checkpoints that monitor the state of genome include the G1 checkpoint prior to onset of DNA replication and the G2 checkpoint prior to onset of mitosis. The G1 checkpoint allows detection and repair of DNA damage before entering S phase, thereby providing a crucial protective function because, when damaged DNA is replicated, it often gives rise to mutations (Hartwell (1992) Cell 71: 543). The G2 checkpoint allows detection and repair of DNA damage before entering mitosis (M phase), thereby providing a crucial function because mitosis without DNA repair may propagate the damage through DNA-damaged daughter cells, or mitosis may fail entirely. Progression through G1 and G2 checkpoints without repairing extensive DNA damage usually results in cell death.
[0003] Inhibition of the cell cycle G2 checkpoint by peptides, peptidomimetics, and "small molecules" has been used to selectively target cancer cells because most cancer cells are defective at one or both of the two major checkpoints of the cell cycle that protect cells from the effects of DNA damage, such that inhibition of the G2 checkpoint allows DNA-damaged cells to re-enter the cell cycle without repairing the DNA damage. (KawabeT. (2004) "G2 checkpoint abrogators as anti-cancer drugs" Mol Cancer Ther 3: 513-519). Although the molecular mechanism of the cell cycle G2 checkpoint was extensively studied, no single molecular target for the therapeutic G2 checkpoint abrogation was established in earlier studies. A phenotype-based screening protocol has been developed to efficiently identify potential G2 checkpoint inhibitors. (Suganuma M. & Kawabe T., EP Application No. 00964563; Sha et al. (2007) Mol Cancer Ther 6: 147-153), where cell cycle phenotype-based screening of G2 checkpoint abrogating peptides identified CBP501 having a unique mechanism of action at the cell cycle G2 checkpoint. (Sha et al. (2007) Mol Cancer Ther 6: 147-153).

[0008] The present invention provides compounds for use in treating a cell proliferation disorder. The present invention provides compounds for use in treating cancer, e.g., for treating undesirable cell proliferation associated with benign and malignant tumor cells, leukemia cells, lymphoma cells, or multiple myeloma cells. The present invention provides compounds for use in abrogating the cell cycle G2 checkpoint in undesirably proliferating cells such as cancer cells, e.g., benign and malignant tumor cells, leukemia cells, lymphoma cells, or multiple myeloma cells. The present invention provides compounds for use in causing adaptation to G2 cell cycle arrest in undesirably proliferating cells such as cancer cells, e.g., benign and malignant tumor cells, leukemia cells, lymphoma cells, or multiple myeloma cells.
[0009] The present invention provides ex vivo or in vitro methods of killing or suppressing an undesirably profilerating cell associated with a cell proliferation disorder by administering to the cell an effective amount of a compound of the invention to abrogate the G2 checkpoint and/or cause adaptation to G2 cell cycle arrest. Compounds of the present invention are provided for use in methods for treating a cell proliferation disorder by administering an effective amount of a compound of the invention to a subject, methods for treating a cell proliferation disorder wherein the cell proliferation disorder is cancer, including but not limited to lymphoma, myeloma, or leukemia and methods for treating cancer by administering an effective amount of a compound and administering at least one additional anti-cancer treatment, e.g., a DNA-damaging agent or a DNA-damaging treatment.
[0010] The invention provides in vitro or ex vivo methods for killing or suppressing cells by contacting cells with a compound of the invention or a pharmaceutical composition of the invention, in combination with a DNA-damaging agent or treatment. The invention provides in vitro or ex vivo methods for selectively sensitizing cells to a DNA-damaging agent and/or treatment, by contacting cells with a compound of the invention ora pharmaceutical composition of the invention, in combination with the DNA-damaging agent or treatment.

[0011] Phenotype-based screening was used to measure the ability of compounds of the invention to cause adaptation to G2 cell cycle arrest in G2-arrested cells. Adaptation to G2 cell cycle arrest and re-entry into the cell cycle can result in death of the previously G2-arrested cell, or suppression (inhibition) of further proliferation of the previously G2-arrested cell. In a non-limiting embodiment, the ability to cause adaptation to G2 cell cycle arrest was measured by contacting cells in which G2 arrest had been induced by irradiation (e.g., gamma (γ) radiation or X-ray radiation), with compounds of the invention at various concentrations and, for each compound at each concentration, determining the percentage of cells that escaped G2 arrest and re-entered the cell cycle, by determining the percentage of cells in G1 phase. The IC5Q value for each compound was calculated as the dosage (usually in μΜ) that caused half-maximal increase of the percentage of cells in G1 phase (the G1 increment) measured for that compound. Certain invention compounds were initially identified by phenotype-based screening of small molecule libraries for activity against G2-arrested cells as described above.

DETAILED DESCRIPTION OF THE INVENTION
Definitions [0018] Unless defined otherwise, technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this invention belongs. As used herein, the following terms have the meanings ascribed to them unless specified otherwise.
[0019] The terms "DNA-damaging treatment" and "DNA-damaging agent" refer to any agent or treatment that directly or indirectly damages DNA, including but not limited to, DNA-damaging drugs (agents), irradiation with DNA-damaging levels of X, gamma (γ), or UV radiation, various kinds of environmental shock, and the like. It is understood that a DNA-damaging treatment or DNA-damaging agent may act directly on DNA, e.g., to disrupt DNA structure or interfere with DNA synthesis, or may act indirectly on DNA by its effects on other cellular systems involved in DNA synthesis and replication, e.g., to disrupt or inhibit the functions of microtubules or DNA topoisomerase. Specific examples of DNA-damaging agents include but are not limited to alkylating agents, nitrosoureas, anti-metabolites, plant alkaloids, plant extracts, radioisotopes, steroid hormones. Additional examples of DNA-damaging agents also include but are not limited to agents known as "DNA-damaging drugs" or "anti-cancer drugs" or "anti-cancer agents" or "DNA-damaging anti-cancer agents," e.g., 5-fluorouracil (5-FU), capecitabine, S-1 (Tegafur, 5-chloro-2,4-dihydroxypyridine and oxonic acid), 5-ethy-nyluracil, arabinosyl cytosine (ara-C), 5-azacytidine (5-AC), 2’,2’-difluoro-2’-deoxycytidine(dFdC), purine antimetabolites (mercaptopurine, azathiopurine, thioguanine), gemcitabine (Gemzar®), bortezomib (Velcade®) pentostatin, allopurinol, 2-fluoro-arabinosyl-adenine (2F-ara-A), hydroxyurea, sulfurmustard (bischloroetyhylsulfide), mechlorethamine, melpha-lan, melpharan, vincristine, chlorambucil, cyclophosphamide, ifosfamide, thiotepa, AZQ, mitomycin C, dianhydrogalac-titol, dibromoducitol, alkyl sulfonate (busulfan), nitrosoureas (BCNU, CCNU, 4-methyl CCNU or ACNU), procarbazine, decarbazine, rebeccamycin, anthracyclins such as doxorubicin (adriamycin; ADR), daunorubibcin (Cerubicine), idaru-bicin (Idamycin) and epirubicin (Ellence), anthracyclin analogues such as mitoxantrone, actinimycin D, non intercalating topoisomerase inhibitors such as epipodophyllotoxins (etoposide=VP16, teniposide=VM-26), podophylotoxin, bleomycin (Bleo), pepleomycin, taxanes, compounds that form adducts with nucleic acid including platinum derivatives, e.g., cisplatin (CDDP), trans analogue of cisplatin, carboplatin, iproplatin, tetraplatin andoxaliplatin, aswellascamptothecin, topotecan, irinotecan (CPT-11), and SN-38. Specific examples of DNA-damaging treatments include radiation e.g., ultraviolet (UV), infrared (IR), X-ray, a- (alpha), β- (beta), or y-(gamma) radiation, as well as environmental shock, e.g., hyperthermia. One of skill in the art can identify and use other DNA-damaging agents and treatments.
[0020] The term "compound of the invention" is intended to refer to a molecule having the structure and activity as disclosed herein and defined in the claims. A compound of the invention can be isolated, pure, substantially pure, or may be in a composition containing a mixture of other components. Purity of a composition containing a compound of the invention can be determined, for example, using analytical chemistry techniques such as high performance liquid chromatography (HPLC), or liquid chromatography-mass spectrometry (LC-MS) or gas chromatography-mass spectrometry (GS-MS), or other analytical techniques known to one of skill in the art. A composition as provided herein may contain one or more compounds of the invention, in a mixture with suitable vehicles, carriers, excipients, inert ingredients, and the like. If desired, a composition as provided herein may contain additional active ingredients including DNA-damaging agents and the like, as well as one or more compounds of the invention, in a mixture with suitable vehicles, carriers, excipients, inert ingredients, and the like.
[0021] The terms "pharmaceutical composition" or "medicament" refer to a composition suitable for pharmaceutical use in a subject, e.g., as a anti-cancer agent. The subject may be any animal wherein compounds of the invention abrogate the cell cycle G2 checkpoint and/or cause adaptation to G2 arrest. In particular, the subject may be a mammal, e.g., a horse, cow, dog, cat, or human. A pharmaceutical composition of the invention is a formulation that can comprise a pharmacologically effective amount of at least one compound of the invention and a pharmaceutically acceptable carrier.
[0022] The terms "cell proliferation disorder" or "proliferative disorder" or "cell proliferative disorder" or "proliferative condition" or "condition characterized by undesirable cell proliferation" or any grammatical equivalent thereof, are understood to refer any pathological or non-pathological physiological condition characterized by aberrant or undesirable proliferation of at least one cell, including but not limited to conditions characterized by undesirable or unwanted or aberrant cell proliferation, conditions characterized by undesirable or unwanted or aberrant cell survival, and conditions characterized by deficient or aberrant apoptosis. The term "cell proliferation" and grammatical equivalents thereof, is understood to encompass both an increase in the number of cells as a result of cell division, as well as an increase in the total mass of cells as a result of cell growth, e.g., by growth of daughter cells after mitosis. One non-limiting example of a "cell proliferation disorder" or "proliferative disorder" or "proliferative condition" or "condition characterized by undesirable cell proliferation" is cancer, e.g., undesirable or unwanted or aberrant proliferation and survival of cancer cells such as cells associated with lymphoma, myeloma, sarcoma, leukemia, or other neoplastic disorders disclosed elsewhere herein and known to one of skill in the art.
[0023] The terms "kill or suppress cells" or "killing or suppressing cells" or "kill or suppress undesirably proliferating cells" or "kill or suppress target cells" or any grammatical equivalent thereof, are understood to refer to results of being contacted with an effective amount of a compound of the invention. The terms "kill" or "killing" are understood to refer to cell death resulting from the effects of a compound of the invention on a cell, in particular death of an undesirably proliferating cell such as a cancer cell, where death may be due to apoptosis, mitotic catastrophe, necrosis, or another cause, depending on the circumstances of the cell. The terms "suppress" or "suppressing" are understood to refer to suppression of cell proliferation resulting from effects of a compound of the invention on a cell, where suppression may be partial or complete. A compound of the invention may cause partial suppression of a cell, such that the cell may cease dividing but continue to grow, or the cell may divide much more slowly, or the cell may grow much more slowly, or a cancer cell may not progress from a pre-metastatic state to a metastatic state, etc. A compound of the invention may cause complete suppression wherein a cell neither divides nor grows, in particular, wherein an undesirably proliferating cell neither divides nor grows.
[0024] The terms "effective amount" or "sufficient amount" or any grammatical equivalent thereof, are understood to refer to an amount of a compound of the invention sufficient to produce at least one desired effect. Effective amounts are determined by any of a variety of measurements including but not limited to: cell death; decreased cell proliferation; decreased numbers of cells; inhibition of cell growth; decreased cell size; decreased cell survival; decreased cell metabolism; apoptosis; mitotic catastrophe; adaptation to cell cycle arrest (i.e., escape from cell cycle arrest, usually leading to re-entry into the cell cycle); markers of cell damage or cytotoxicity; indirect indicators of cell damage or cytotoxicity such as tumor shrinkage; improved survival of a subject; or disappearance of markers associated with undesirable, unwanted, or aberrant cell proliferation. For example, where it is desired to inhibit undesirable proliferation of a particular cell or cell type, an effective amount will be an amount that detectably decreases cell division, or decreases cell metabolism, or increases cell death, or decreases cell survival, of that cell or cell type. A desired effect may be a selective effect, e.g., an "effective amount" is an amount that kills or suppresses target cells while having little or no cytotoxic effect on non-target cells, or an amount that produces a desired therapeutic benefit in a subject having a cell proliferation disorder, while having little or no adverse effect on the subject. The compounds of the invention are for use in methods of treating a cell proliferation disorder by administering an effective amount of at least one compound of the invention, where the effective amount of at least one compound can be administered in vitro or ex vivo to treat cells, or the compound can be administered in vivo to a subject having a cell proliferation disorder.
[0025] The terms "cell cycle G2 checkpoint" or "G2 checkpoint" or any grammatical equivalent thereof, refer to the G2 checkpoint occurring at the end of G2 phase of the cell cycle. During the G2 "gap" phase between DNA synthesis (S phase, DNA replication in preparation for mitosis) and mitosis (M phase, cell division to produce daughter cells), the cell continues to grow and produce new proteins. The G2 checkpoint at the end of the G2 phase is a control checkpoint where a number of factors are checked to ensure the cell is ready to enter mitosis (M phase). Functions of the G2 checkpoint includes detecting DNA damage. If the G2 checkpoint is passed, then entry into M phase is initiated. If the G2 checkpoint detects DNA damage, the G2 checkpoint can generate a signal leading to "cell cycle arrest" or "G2 cell cycle arrest" or G2 arrest," that restricts the onset of mitosis until DNA replication and repair are complete, thereby preventing transmission of DNA damage to daughter cells. It is understood that, because DNA damage can trigger or activate the G2 checkpoint and certain G2 checkpoint-related cellular activities, the term "DNA damage-induced G2 checkpoint" and grammatical equivalents thereof, can also be used in certain contexts. It is further understood that the DNA damage-induced G2 checkpoint can be induced or triggered by DNA-damaging agents or treatments.
[0026] The terms "abrogate the G2 checkpoint" or "abrogate the cell cycle G2 checkpoint" or "abrogation of the G2 checkpoint" or "G2 abrogation" or "G2 checkpoint abrogation" or "disrupt the G2 checkpoint" or "inhibit the G2 checkpoint" or "suppress the G2 checkpoint" or any grammatical equivalent thereof, are intended to refer to the ability of compounds of the invention to abrogate, disrupt, inhibit, repress, or suppress the G2 checkpoint. A cell in which the G2 checkpoint is abrogated may have a complete absence of the activity of the G2 checkpoint (G2 checkpoint arrest, or complete G2 checkpoint abrogation). A cell in which the G2 checkpoint is abrogated may exhibit a decrease in the length of time the cell is in the G2 checkpoint, e.g. a G2 checkpoint having a decrease in duration of minutes, hours, days, weeks or longer under appropriate conditions. For example, a decrease in the length of G2 checkpoint time would mean that a cell which is normally in G2 for a certain time, e.g., 4 hours, when contacted with an invention compound, is in G2 for less than 4 hours, e.g., 3.5, 3, 2.5, 2, 1 or fewer hours. Thus, "G2 checkpoint abrogation" refers to any amount of abrogation of the G2 checkpoint. It is understood that the result of G2 checkpoint abrogation is that the cell will enter mitosis (M phase) without DNA repair, which should have little or no deleterious effect on undamaged (normal) cells, and which should result in severe adverse effects on DNA-damaged cells, often leading to cell death due to apoptosis, mitotic catastrophe, or necrosis.
[0027] "Cell cycle arrest" or "G2 cell cycle arrest" or "G2 arrest" "G2-M cell cycle arrest" or any grammatical equivalent thereof, refers to a state wherein a cell does not exit G2 to enter mitosis (M phase) such that the cell is considered to be ’arrested’ at the G2 phase. G2 cell cycle arrest is often observed in DNA-damaged cells such as many cancer cells. G2 cell cycle arrest can result from any of a number of cellular activities, including but not limited to certain activities of the G2 checkpoint. The DNA damage found in many cancer cells can trigger G2 cell cycle arrest. G2 cell cycle arrest can be induced or enhanced by treating a cell with DNA-damaging agents such as adriamycin, doxorubicine, or bend-amustine (an alkylating agent), or DNA-damaging treatments such as irradiation with a triggering dose of X, gamma (γ), or UV radiation (sometimes referred to as "radiation-induced G2 arrest").
[0028] "Adaptation" or "adaptation to cell cycle arrest" or "adaptation to G2 cell cycle arrest" or "adaptation to G2 arrest" refers to lifting or abrogation of G2 cell cycle arrest, such that formerly arrested cells re-enter the cell cycle. Adaptation to G2 cell cycle arrest likewise refers to escape from G2 cell cycle arrest. Compounds of the present invention can cause adaptation to G2 cell cycle arrest in G2-arrested cells. In accordance with one aspect of the invention, "adaptation" or "adaptation to cell cycle arrest" or "adaptation to G2 cell cycle arrest" or "adaptation to G2 arrest" can refer to escape from a condition of G2 cell cycle arrest imposed by G2 checkpoint activation, in particular, G2 cell cycle arrest imposed by activation of the DNA-damage-induced G2 checkpoint. It is understood that adaptation to G2 cell cycle arrest results in formerly G2-arrested cells re-entering the cell cycle without repairing the DNA damage that triggered the G2 arrest. Adaptation to G2 cell cycle arrest, wherein DNA-damaged cells re-enter the cycle, often results in cell death due to apoptosis, mitotic catastrophe, or necrosis. Because the mechanism that promotes the cell cycle G2 arrest after DNA damage appears to be conserved among species from yeast to human, it is understood that compounds of the present invention can cause adaptation to G2 cell cycle arrest in numerous species, in particular in all eukaryotic species.
[0029] While the G2 checkpoint-abrogating activity of the compounds of the invention may be related to the ability to cause adaptation to G2 cell cycle arrest, it is also understood that compounds of the invention may cause adaptation to G2 cell cycle arrest by other mechanisms unrelated to abrogation of the G2 checkpoint. Thus, depending on the particular circumstances and without wishing to be limited by this definition, abrogation of the G2 checkpoint can refer, at least in part, to abrogating the ability of a cell to arrest the cell cycle at the G2 checkpoint, leading to adaptation to G2 cell cycle arrest. In particular, abrogation of the DNA damage-induced G2 checkpoint by compounds of the invention, under conditions that would normally trigger G2 cell cycle arrest, can include abrogation of a G2-checkpoint-generated signal involved in triggering G2 cell cycle arrest.

Biological activities of compounds of the invention [0073] The present invention provides compounds to treat cell proliferation disorders. The present invention provides compounds that can be used to kill orsuppress undesirably proliferating cells. The present invention provides compounds that can be used to treat cell proliferation disorders by selectively killing or suppressing undesirably proliferating cells. The present invention provides compounds that can be used to treat cell proliferation disorders by selectively killing or suppressing undesirably proliferating cells that have accumulated DNA damage ("DNA-damaged cells"). In mixed populations of normal cells and undesirably proliferating cells, compounds of the invention can be used to selectively kill or suppress undesirably proliferating cells while having little or no cytotoxic effect on the normal cells. In mixed populations of normal cells and undesirably proliferating DNA-damaged cells, compounds of the invention can be used to selectively kill or suppress undesirably proliferating DNA-damaged cells while having little or no cytotoxic effect on the normal cells. In particular, compounds of the invention can be used to selectively kill cancer cells or suppress proliferation of cancer cells, while having little or no cytotoxic effect on "normal" non-cancerous cells. The present invention provides compounds for use in methods for selectively targeting DNA-damaged cells. The present invention provides compounds for use in methods for selectively targeting cells with an impaired G1 cell cycle checkpoint. The present invention provides compounds for use in methods for selectively targeting cancer cells.
[0074] Conventional treatments for cell proliferation disorders often include DNA-damaging agents and treatments as described elsewhere herein. These conventional treatments, often used as anti-cancer treatments, have been selected to kill rapidly cycling (proliferating) cells in hopes of killing the undesirably proliferating cells characteristic of the proliferation disorder. Examples of such conventional treatments include, but are not limited to, cytotoxic agents and/or irradiation with α, β, γ, X- and/or UV radiation. However, conventional treatments often cause patients to suffer adverse effects on normal cells that are also proliferating, e.g., diarrhea due to damage to intestinal epithelial cells, hair loss due to damage to hair follicle cells, and anemia due to damage to blood cell progenitors, all of which are among the most rapidly proliferating cells in the normal body. These adverse effects often hamper treatments. Thus, medicines that specifically target undesirably proliferating cells such as cancer cells, without harming normal cells, have been long awaited in the clinic.
[0075] While the invention is not limited by any particular mechanism of action, and without wishing to be limited by this theory, compounds of the invention may kill orsuppress undesirably proliferating cells by abrogating the G2 checkpoint in proliferating cells, and/or by causing adaptation to G2 cell cycle arrest in G2-arrested cells. Thus, the invention provides compounds for use in methods for killing or suppressing undesirably proliferating cells by contacting the cells with at least one compound of the invention in an amount sufficient to abrogate G2 cell cycle checkpoint and/or cause adaptation to G2 cell cycle arrest.
[0076] Without wishing to be limited by this theory, abrogation of the G2 checkpoint in DNA-damaged cells would cause the DNA-damaged cells to progress through the cell cycle with without repairing the DNA damage. Likewise, adaptation to G2 cell cycle arrest in DNA-damaged cells would cause the formerly-arrested DNA-damaged cells to enter mitosis without repairing the DNA damage. It is generally understood that normal cells rely on the G1 checkpoint as the main checkpoint for detecting DNA damage or defects during the cell cycle, and do not appear to use the G2 checkpoint as much for detecting DNA damage or defects, whereas cells having an impaired or defective G1 checkpoint, e.g., most cancer cells, have to depend on the G2 checkpoint to detect DNA damage or defects, and to initiate repair before the cell enters mitosis. Thus, abrogation of the G2 checkpoint in cells with an impaired G1 checkpoint would cause the cells to progress through the cell cycle with without repairing any accumulated DNA damage. Likewise, adaptation to G2 cell cycle arrest in cells with an impaired G1 checkpoint would cause the formerly-arrested cells to enter mitosis without repairing any accumulated DNA damage. The term "DNA damage" is understood to encompass DNA damage unrelated to the G1 checkpoint, as well as DNA damage resulting from an impaired G1 checkpoint, such that cells with an impaired G1 checkpoint can be considered "DNA-damaged cells." In all the situations described above, progressing through the cell cycle without repairing DNA damage is expected to result in suppression or death of the DNA-damaged cells.
[0077] While the invention is not limited to a particular mechanism of action, it has been observed that compounds of the invention can abrogate the G2 checkpoint in proliferating cells, and can cause adaptation to G2 cell cycle arrest. Abrogation of the G2 checkpoint in proliferating DNA-damaged cells allow the DNA-damaged cell to progress through G2 and enter mitosis without sufficient repair of DNA damage. Adaptation to G2 arrest of DNA-damaged cells, resulting in re-entry of the formerly arrested DNA-damaged cells into the cell cycle, allows the DNA-damaged cell to enter mitosis without sufficient repair of DNA damage. It is further understood that if a DNA-damaged cell progresses further into the cell cycle with a impaired G1 checkpoint and enters S phase, additional damage, defects, and errors are expected. In all the situations described above, the accumulation of damage could result in apoptosis, mitotic catastrophe, necrosis, or cell suppression. Because most cancer cells have DNA damage and/or an impaired (defective) G1 checkpoint, compounds of the invention can be used to kill or suppress cancer cells because abrogation of the G2 checkpoint or adaptation to G2 arrest will have cytotoxic effects on the cancer cells, e.g., death or suppression of the cancer cells.
[0078] For normal cells without DNA damage, it is expected that abrogation of the cell cycle G2 checkpoint by compounds of the invention will have little or no cytotoxic effect. Furthermore, as normal cells without DNA damage are not likely to be in G2 arrest, it is expected that the ability of compounds of the invention to cause adaptation to G2 arrest will have little or no cytotoxic effect. Thus, in a population of cells that includes undesirably proliferating DNA-damaged cells and normal cells, compounds of the invention can be used to selectively kill or suppress DNA-damaged cells, while having little or no cytotoxic effect on normal cells. In a population of cells including undesirably proliferating cancer cells and normal cells, compounds of the invention can be used to selectively kill or suppress the cancer cells, while having little or no cytotoxic effect on normal cells.
Use of compounds of the invention to treat cells [0079] Any cell whose proliferation is undesired can be treated in vitro, ex vivo or in vivo with compounds of the invention. Candidate cells can be identified by contacting a test cell with an invention compound alone, or in combination with a DNA-damaging treatment or other anti-cancer treatment, and determining if the contacted cell exhibits decreased proliferation, increased cell death, or adaptation to cell cycle arrest. Candidate cells can be identified on the basis of features including but not limited to, DNA damage, aberrant growth or proliferation (in vivo or in vitro) cellular morphology, or expression of cancer markers. A clinical diagnosis of a proliferative disorder such as cancer can be relied upon as evidence of cells to be treated in vitro, ex vivo, or in vivo with compounds of the invention.
[0080] Cells can be treated in vitro with compounds of the invention. Cells can be removed from a subject, treated ex vivo using compounds of the invention, and, by way of example, returned to the subject. Compounds of the invention are for use in methods in which cells can be treated in vivo, where compounds of the invention may be administered systemically to a subject, e.g. orally or intravenously, or by a targeted administration method, e.g., injection into a tumor site, intraperitoneal injection, or by associating compounds of the invention with delivery devices such as ligands, antibodies, molecular cages, or liposomes capable of targeting at least one cell to be treated.
Compounds of the invention for use in methods to treat subjects [0081] Subjects appropriate for treatment using compounds of the invention include subjects currently undergoing treatment for a cell proliferation disorder, or candidates for treatment for a cell proliferation disorder, e.g., subjects currently undergoing, or designated as candidates for, anti-cancer treatment. Subjects appropriate for treatment include those having a cell proliferation disorder, e.g., a diagnosis of cancer. Candidate subjects include subjects at risk of developing a cell proliferation disorder. The compounds of the invention are therefore applicable for use in methods to treat a subject who is at risk of developing a cell proliferation disorder but who has not yet exhibited overt symptoms of the disorder and/or who has not yet received a diagnosis of a cell proliferation disorder.
Compounds of the invention for use in methods to treat cell proliferation disorders.
[0082] Cell proliferation disorders amenable to treatment using compositions provided herein include pathological conditions (diseases), both benign and neoplastic, and non-pathological physiological conditions, characterized by abnormal or undesirable cell numbers, cell growth or cell survival. Pathological disorders or conditions may constitute a disease state, in particular all types of cancer, including cancerous growths, oncogenic processes, métastasés, metastatic cells and tissues, and malignantly transformed cells, tissues, or organs. Cell proliferation disorders can be non-pathologic, including some types of fibrotic tissue growth (e.g., during wound repair resulting in scarring), certain blood vessel proliferative disorders, and certain benign hyperplasias. The present disclosure provides sufficient guidance and exemplary embodiments to enable one of skill in the art to identify cell proliferation disorders suitable for treatment using compositions and methods provided herein, and to develop protocols for such treatment.
[0083] Cells comprising the proliferative disorder may be aggregated in a cell mass or may be dispersed. The term "solid tumor" refers to hyperplasias, neoplasias or métastasés that typically aggregate together and form a mass. Particular examples include visceral tumors such as gastric or colon cancer, hepatomas, venal carcinomas, lung and brain tumors/cancers. A "liquid tumor" generally refers to neoplasias of the haematopoetic system, such as lymphomas, myelomas and leukemias, or neoplasias that are diffuse in nature, as they do not typically form a solid mass. Particular examples of leukemias include acute and chronic lymphoblastic, myeloblastic and multiple myeloma.
[0084] Such disorders include neoplasms or cancers, which can affect virtually any cell or tissue type, e.g., carcinoma, sarcoma, melanoma, metastatic disorders or haematopoietic neoplastic disorders. A metastatic tumor can arise from a multitude of primary tumor types, including but not limited to breast, lung, thyroid, head and neck, brain, lymphoid, gastrointestinal (mouth, esophagus, stomach, small intestine, colon, rectum), genito-urinary tract (uterus, ovary, cervix, bladder, testicle, penis, prostate), kidney, pancreas, liver, bone, muscle, skin, etc.
[0085] Carcinomas refer to malignancies of epithelial or endocrine tissue, and include respiratory system carcinomas, gastrointestinal system carcinomas, genitourinary system carcinomas, testicular carcinomas, breast carcinomas, prostatic carcinomas, endocrine system carcinomas, and melanomas. Exemplary carcinomas include those forming from the cervix, lung, prostate, breast, head and neck, colon, liver and ovary. The term also includes carcinosarcomas, e.g., which include malignant tumors composed of carcinomatous and sarcomatous tissues. Adenocarcinoma includes a carcinoma of a glandular tissue, or in which the tumor forms a gland like structure.
[0086] Sarcomas refer to malignant tumors of mesenchymal cell origin. Exemplary sarcomas include for example, lymphosarcoma, liposarcoma, osteosarcoma, and fibrosarcoma.
[0087] As used herein, the term "haematopoietic proliferative disorder" means a disease involving hyperplastic/neo-plastic cells of haematopoietic origan, e.g., arising from myeloid, lymphoid orerythroid lineages, or precursor cells thereof. Typically, the diseases arise from poorly differentiated acute leukemias, e.g., erythroblastic leukemia and acute meg-akaryoblastic leukemia. Additional exemplary myeloid disorders include, but are not limited to, acute promyeloid leukemia (APML), acute myelogenous leukemia (AML) and chronic myelogenous leukemia (CML); lymphoid malignancies include, but are not limited to, acute lymphoblastic leukemia (ALL), which includes B-lineage ALL and T-lineage ALL, chronic lymphocytic leukemia (CLL), prolymphocytic leukemia (PLL), hairy cell leukemia (HLL) and Waldenstrom’s macroglob-ulinemia (WM). Additional malignant lymphomas include, but are not limited to, non-Hodgkin lymphoma and variants thereof, peripheral T cell lymphomas, adult T cell leukemia/lymphoma (ATL), cutaneous T-cell lymphoma (CTCL), large granular lymphocytic leukemia (LGF), Hodgkin’s disease and Reed-Stern berg disease.

The invention provides compositions for use in methods for treating cancer using compounds of the invention. The invention provides com positions for use in methods for killing orsuppressing cancer cells using compounds of the invention. The invention provides compounds of the invention, for use in methods for treating cell proliferation disorders in vivo, in vitro, and ex vivo. The invention provides compounds of the invention, for use in methods of treating cancer in vivo, in vitro, and ex vivo. The invention provides pharmaceutical compounds of the invention, for use in methods of killing or suppressing cancer cells in vivo, in vitro, and ex vivo. The invention provides pharmaceutical compositions (medicaments) containing compounds on the invention, for all uses described herein, including but not limited to, treating cell proliferation disorders, killing orsuppressing cancer cells, and treating cancer.
[0089] The invention provides compositions for use in methods that include at least one compound of the invention in combination with at least one additional active ingredient. The invention provides pharmaceutical compositions (medicaments) including at least one compound of the invention in combination with at least one additional active ingredient, for use in methods of treating cell proliferation disorders. In particular, the invention provides compositions for use in methods that include compounds of the invention in combination with at least one anti-cancer treatment. The term "anticancer treatment" for use in combination with compounds of the invention includes any anti-cancer, anti-proliferative, DNA-damaging, or anti-tumor treatment as disclosed herein, including the "DNA-damaging treatments" and "DNA-damaging agents" recited above, or any such treatment known in the art. For example, an anti-cancer (anti-cell proliferative, anti-tumor) treatment may comprise radiation treatment or surgical resection, optionally in combination with drug treatment. The treatment may comprise administration of a chemical substance, such as a radioisotope, an anti-cancer drug such as a chemotherapeutic agent, or genetic therapy, such as an anti-oncogene (e.g., Rb, DCC, p53, etc.), a dominant negative oncogene or an antisense to an oncogene. The compounds of the invention are for use in methods wherein the compounds can be administered prior to, contemporaneously with or following other treatment protocols. For example, the compounds of the invention are for use in methods wherein a candidate subject for anti-cell proliferative therapy (e.g., radiation therapy, chemotherapy, gene therapy, surgical resection, etc.) can be administered an invention compound prior to initiating the anti-cell proliferative therapy. Thus, compounds of the invention for use in prophylactic treatment methods are provided.
[0090] As demonstrated in exemplary embodiments described in the Examples and discussed below, compounds of the invention can be used alone or in combination, in vivo, ex vivo, and in vitro, in methods to treat cell proliferation disorders. As demonstrated in exemplary embodiments described in the Examples and discussed below, compound compounds of the invention can be used alone or in combination, in vivo, ex vivo, and in vitro, in methods to treat cancer. As demonstrated in exemplary embodiments described in the Examples and discussed below, compound compounds of the invention can be used alone or in combination, in vivo and in vitro, in methods to kill or suppress cancer cells.
Effects of compounds of the invention [0091] Typically an "effective amount" or "sufficient amount" of a compound of the invention is administered, where that is an amount (concentration, dose, level) sufficient to produce a desired effect. Effective amounts are determined by any of a variety of measurements including: cell death (e.g., increase in percentage of cells insubGI phase), decreased cell proliferation, decreased numbers of cells, decreased cell mass, increased apoptosis, decreased survival, or adaptation to cell cycle arrest (escape from cell cycle arrest). For example, where it is desired to inhibit cell proliferation, an effective amount will be an amount that detectably decreases cell proliferation, or increases cell death, or decreases cell survival. The amount can therefore be sufficient to reduce target cell numbers, stabilize target cell numbers or inhibit increases in target cell numbers. An effective amount can be an amount sufficient to increase survival time of a subject having a cell proliferation disorder.
[0092] For example, where the disorder comprises a solid tumor, an effective amount of a compound of the invention could reduce tumor size, stabilize tumor size, or increase the survival time of a subject having the tumor. As shown in the exemplary embodiment in Example 4, five (5) representative compounds of the invention showed selective cytotoxicity In vivo against cancer cells, and no detectable cytotoxicity In vivo against normal cells, as illustrated by dramatic increases in tumor host survival.
[0093] Where the disorder comprises a "liquid tumor" an effective amount of a compound of the invention could reduce numbers of tumor cells, stabilize the number of tumor cells, inhibit further increases in the number of tumor cell, or cause cell-cycle-arrested cancer cells to re-enter the cell cycle (adaptation to cell cycle arrest). In addition, effective amounts of compounds of the invention could prevent or inhibit progression of the proliferative disorder, e.g., reduce, inhibit, or prevent metastasis.
[0094] An effective amount of a compound of the invention may be an amount that produces a desired effect without producing an unacceptable or undesirable effect. An effective amount of a compound of the invention may be an amount that kills or suppresses target cells (e.g., cancer cells) while having little or no cytotoxic effect on non-target cells (e.g., normal cells), or an amount that produces a desired therapeutic benefit in a subject having a cell proliferation disorder, while having little or no adverse effect on the subject. Further, an effective amount of a compound of the invention may be an amount that, in combination another treatment, produces a desired effect without producing an unacceptable undesirable effect. As shown in exemplary embodiments in Example 7 and illustrated in Tables 4-11 below, compound S00109 has little or no cytotoxic effect on normal cells at concentrations can kill or suppress cancer cells. Further as shown in exemplary embodiments in Example 7 and illustrated in Tables 4-11 below, compound S00109 can be used in combination with another anti-cancer treatment to kill or suppress cancer cells, at a concentration of S00109 that has little or no cytotoxic effect on normal cells.
[0095] Effective amounts of compounds of the invention can objectively or subjectively reduce or decrease the severity or frequency of symptoms associated with the disorder or condition. For example, an effective amount of an invention compound could reduce pain, nausea or other discomfort, or increase appetite or subjective well-being.
[0096] Effective amounts of compounds of the invention could reduce the amount (e.g., dosage) or frequency of treatment with another protocol. For example, a cancer patient treated with an invention compound may require less anti-cancer DNA-damaging agent or treatment in order to achieve the desired level of inhibition of cancer cell proliferation, i.e., a desired level of killing or suppression of proliferating cancer cells.
[0097] Methods described herein that lead to an improvement in the subject’s condition or a therapeutic benefit that may be permanent, may extend over a longer period of time, e.g., months or years, or may be relatively short in duration, e.g., the improvement may last several hours, days or weeks. An effective amount need not achieve a complete ablation of any or all symptoms of the condition or disorder. An amount effective to provide one or more beneficial effects, as described herein or known in the art, is referred to as an "improvement" of the subject’s condition or "therapeutic benefit" to the subject.
[0098] An effective amount of an invention compound can be determined based upon animal studies or optionally in human clinical trials. The skilled artisan will appreciate the various factors that may influence the dosage and timing required to treat a particular subject including, for example, the general health, age, or gender of the subject, the severity or stage of the disorder or condition, previous treatments, susceptibility to undesirable side effects, clinical outcome desired and the presence of other disorders or conditions. Such factors may influence the dosage and timing required to provide an amount sufficient for therapeutic benefit. The dosage regimen also takes into consideration the pharmacokinetics, i.e., the pharmaceutical composition’s rate of absorption, bioavailability, metabolism, and clearance. In addition, doses or treatment protocols may be specifically tailored to the subject or modified based on pharmacogenomic data.
Adaptation to DNA-damage-induced G2 cell cycle arrest [0099] While the invention is not limited to a particular mechanism of action, it has been determined that compounds of the invention can cause adaptation to G2 cell cycle arrest. Thus, the invention provides composition and methods for abrogating or escaping from the G2 cell cycle arrest, in particular G2 cell cycle arrest triggered by DNA damage. In DNA-damaged cells, the functions of the DNA-damage-induced G2 checkpoint are understood to include recognition of DNA damage and generation of a signal that produces cell cycle-arrest, such that the DNA-damaged cells are arrested in G2 phase until repair is completed. Compounds of the invention can cause cells in G2 cell cycle arrest to re-enter the cell cycle, possibly by abrogating the DNA-damage-induced G2 checkpoint in the G2-arrested cells. As demonstrated in embodiments presented in the examples, tables and figures of the present disclosure, compounds of the invention can induce cells in G2 cell cycle arrest (i.e., cells having pre-existing DNA damage) to re-enter the cell cycle, proceeding through the G2 and M phases and entering G1 (DNA doubling) phases with unrepaired DNA damage, leading to cell death or cell suppression, usually by mitotic catastrophe or apoptosis.
[0100] In an exemplary embodiment described in Example 1 and shown in Figure 1, Jurkat cells (a human T-cell lymphoma-derived cell line) were "pre-arrested" at the G2 phase by X-ray irradiation and treated with S00109 or S01860 at various dosages. Adaptation to G2 cell cycle arrest was determined by measuring the percentage of cells in G1 phase, where cells in G1 were identified by having 2N DNA. In these embodiments, cells exposed to S00109 orS01860 showed a dose-dependent increase in the percentage of cells in G1 phase (the "G1 increment"), These results indicated that exposure to S00109 or S01860 at concentrations from 0.019 μΜ to 0.625 μΜ caused G2-arrested cells to re-enter the cell cycle and proceed through the M phase and enter the G1 phase. In contrast, only a few percent of cells in the population of untreated G2-arrested cells (i.e., no S00109 or S01860 exposure) entered G1 phase.
[0101] Additional non-limiting exemplary embodiments of adaptation to G2 cell cycle arrest by compounds of the invention, are presented in Examples 5 and 6, and illustrated in Tables 1,2 and 3, setting forth the structures and IC50 values (the concentration causing half-maximal G1 increment) for approximately 144 compounds of the invention. The extensive data provided in Tables 1,2 and 3 permitted structure-activity determinations.
[0102] Other measurements of cell cycle activity can also be relied upon to demonstrate the ability of the compounds of the invention to abrogate the G2 cell cycle and/or cause adaptation to DNA-damage-induced cell cycle arrest. In an exemplary embodiment described in Example 1 and illustrated in Figure 2, histone H3 phosphorylation was measured, where increased phosphorylation of histone H3 indicated adaptation to (escape from) DNA-damage-induced cell cycle arrest. G2 cell cycle arrest was induced in Jurkat cells by DNA damage, i.e., by delivering a 10 Gy dose of X rays to produce "pre-arrested" cells. Pre-arrested cells were exposed to compound S00109 (also called S109) at 0.3 μΜ or 1 μΜ, and significant increases in histone H3 phosphorylation were observed over a 24-hour treatment period. Without wishing to be limited by this theory, compounds of the invention presumably caused adaptation to (escape from) DNA-damage-induced cell cycle arrest by abrogating the DNA-damage-induced G2 checkpoint.
Compounds on the invention have cytotoxic effects on cancer cells [0103] Compounds of the invention can have a cytotoxic effect on cancer cells, without any additional treatment. Thus, the invention provides compositions, including for use in methods for killing or suppressing cancer cells without any additional treatment. In an exemplary embodiment described in Example 2 and shown in Figure 4, exposure of human cancer cells to S00109 alone has a dose-dependent cytotoxic effect on the cancer cells as measured by a colony formation assay (Figure 4, "0 Gy" unfilled circles, solid line, indicating no radiation treatment).
[0104] In non-limiting exemplary embodiments described in Example 4 and shown in Figures 6, 7, and 8, compounds of the invention are provided that have a cytotoxic effect on cancer cells, without any additional anti-cancer treatment, and without cytotoxic effects on normal cells. In the exemplary embodiments in Figure 4, mice received xenografts of human myeloma cells by intraperitoneal transplantation, and the effects of com pounds of the invention on survival rates were measured. As described in Example 4 and shown in Figures 6, 7, and 8, treatment with S00109, S01860, S03518, S03405 or S03747 alone was sufficient to prolong the survival of mice with xenografts of human myeloma cells, indicating that S00109, S01860, S03518, S03405 or S03747 had cytotoxic effects on the transplanted cancer cells in the xenograft. As shown in the embodiment in Figure 6, treatment with S00109 (by intraperitoneal injection) had a much greater therapeutic effect on survival than the "standard" dexamethasone treatment, or no treatment at all. As shown in Figures 7 and 8, oral administration of various representative compounds of the invention produced dramatic increases in survival rates, where some treatments had 100% survival rates at the end of the experiment. These results demonstrate that compounds of the invention, as illustrated by the five (5) distinct representative compounds tested in Example 4, can have selective cytotoxicity against cancer cells, and no detectable cytotoxicity against normal cells (i.e., the normal cells of the mouse tumor graft host). These in vivo results demonstrate that compounds of the invention, as illustrated by the five (5) distinct representative compounds tested in Example 4, can have selective cytotoxicity in vivo against cancer cells, and no detectable cytotoxicity in vivo against normal cells. These results demonstrate that compounds of the invention, as illustrated by the five (5) distinct representative compounds of the present invention administered by different routes in Example 4, are suitable for use in methods wherein the compounds can be administered to a subject in an effective amount to treat a proliferative disorder in a subject.
Compounds of the invention can sensitize cells to anti-cancer treatments [0105] Compounds of the invention can increase, or exacerbate, the cytotoxic effects of other treatments. Thus, the invention provides compositions for use in methods for sensitizing cells to anti-cancer treatments, in particular for sen sitizing cells to DNA-damaging agents and treatments. In exemplary embodiments described in Example 2 and shown in Figure 4, when human cancer cells that have been "pre-arrested" in G2 by X-ray irradiation are also exposed to S00109, the combination treatment has a higher cytotoxic effect on the cells as measured by a colony formation assay. In Figure 4, the sensitizing effect of compounds of the invention is best illustrated for cells that received a dose of 1 Gy ("1 Gy" solid circles, dashed line) and treatment with various doses of S00109, where S00109 showed a dose-dependent additive effect on cytotoxicity. In an exemplary embodiment described in Example 3 and shown in Figure 5, combination treatments of S00109 and dexamethasone have much greater cytotoxicity than either treatment alone, as measured by the percentage of cells in subG1 phase, i.e., the percentage of dead cells.
[0106] In an exemplary embodiment described in Example 2 and shown in Figure 3, expression of phosphorylated γ-FI2AX was measured as an indicator of cytotoxicity. Cells treated with X-ray-irradiation alone showed increased expression of phosphorylated y-FI2AX over a 48-hour period. The sensitizing or "additive’ effect of compounds of the invention can be seen in cells treated with X-ray-irradiation followed by exposure to 1 μΜ S00109 (indicated as "S-109 +" in figure legend) resulted in significantly higher levels of phosphorylated y-FI2AX expression over the same 48 hour period, indicating significantly higher levels of cytotoxicity due to administration of S00109.
Compounds of the invention have selective cytotoxicity toward cancer cells [0107] In accordance with yet another aspect of the invention, compounds of the invention can selectively kill or suppress target cells, in particular cancer cells, to the with little or no cytotoxic effect on normal (non-target) cells. Most conventional anti-cancer agents target proliferating cells irrespective of whether they are cancer cells or normal cells, with the result that most conventional anti-cancer medicines give rise to side effects such as nausea, diarrhea, or hair loss. In contrast, compounds of the invention selectively target cells having conditions such as an impaired G1 checkpoint, G2 cell cycle arrest, or other types of DNA damage, selectively killing or suppressing the target cells while having little or no cytotoxic effect on normal cells.
[0108] Non-limiting exemplary embodiments of the selectivity of compounds of invention are described in Example 7 and shown in Tables 4 to 11, where compounds of the invention were not cytotoxic for normal cells at concentrations at which compounds of the invention had severe cytotoxic effects on cancer cells and DNA-damaged cells (e.g., irradiated cells). Thus, the invention provides compounds for use in methods for selectively targeting DNA-damaged cells such as cancer cells, with little or no cytotoxic effect on normal (undamaged) cells, by contacting the cells with at least one compound of the invention in an amount sufficient to abrogate the G2 checkpoint. The invention provides pharmaceutical compositions containing at least one compound of the invention, suitable for use in methods for selectively targeting DNA-damaged cells such as cancer cells, with little or no cytotoxic effect on normal (undamaged) cells.
Use of compounds of the invention for screening [0109] Compounds of the invention can be used in cell cycle phenotype-based screening protocols, e.g., as disclosed by Sha et al. ((2007) Mol Cancer Ther, 6: 147-153) to identify candidate compounds that may interact with the G2 checkpoint and/or with other processes involved in adaptation to G2 cell cycle arrest. Compounds of the invention can be used in screening protocols to identify candidate compounds for therapeutic G2 checkpoint abrogation and/or therapeutic adaption to G2 arrest. This screening protocol can be used to identify compounds having desired biological activity. Compounds thus identified can be further evaluated for selective cytotoxic activity against cancer cells. Compounds can be evaluated in combination treatments with conventional anti-cancer agents such as dexamethasone.
[0110] The following examples are offered to illustrate, but not to limit the claimed invention.
EXAMPLES
Example 1: Effects of test compounds S00109 and S01860 on Jurkat cells arrested atG2 phase.
[0111] Jurkat cells (a human T cell lymphoma-derived cell line) were arrested at the G2 phase by X-ray irradiation at 10 Gy, and cultured for 24 hours in 10% fetal calf serum (FCS)/RPMI1640 at 37°C with 5% C02/air. (FCS was from Equitech-Bio, Kerrville, TX, and RPMI1640 was from Sigma-Aldrich, St. Louis, MO.) Test compounds were added to the medium at the indicated doses, and the cells were cultured under the conditions described above, for an additional 24 hours before harvesting.
[0112] Flarvested cells were stained with Krishan’s buffer (0.1% sodium citrate, 50 μg/ml propidium iodide, 20 μg/ml RNase A, 0.5% Nonidet P-40) and analyzed by flow cytometry (BD Biosciences, Franklin Lakes, NJ) to identify the cell stage of each cell in the sample. Cells in G1 phase were identified by having doubled (2N) DNA content. Figure 1 shows the percentage of cells in G1 phase after treatment with each compound at the indicated dosages.
[0113] The IC50 value for each compound was calculated as the dosage showing half maximal activity to induce the increase of the percentage of cells in G1 phase (the G1 increment). IC50 values were used to measure the activity of compounds and to determine structure-activity relationships.
[0114] As shown in Figure 1, populations of pre-arrested Jurkat cells treated with compound S00109 or S01860 for 24 hours showed a significant increase in the number of G1 cells, indicating the cells were able to enterthe cell cycle again.
Histone H3 phosphorylation [0115] Increased numbers of cells in G1 phase ("G1 cells" detected by 2N DNA) after X-ray treatment indicated that the G2 checkpoint had been abrogated and/or cells had adapted to (escaped from) the G2 cell cycle arrest imposed by activation of the G2 checkpoint by the X-ray treatment (i.e., activation of the DNA-damage-induced G2 checkpoint by the X-ray treatment). The level of histone H3 phosphorylation was measured in pre-arrested cells treated with test compounds, to confirm that pre-arrested cells had re-entered the cell cycle and passed through M phase before proceeding to G1 phase. Increased phosphorylation of histone H3 indicated adaptation to (escape from) damage-induced cell cycle arrest or G2/M checkpoint abrogation.
[0116] Jurkat cells were irradiated with 10 Gy X-rays and cultured 24 hour in 10% FCS-RPMI. Test compound S00109 was added to the culture medium at 0.3 or 1 μΜ and cells were cultured with test compound for treatment times from 0 to 24 hours. The cells were fixed with cold ethanol, treated with 0.1% saponin/PBS, stained with anti-phospho-histone H3 (Ser10) (Upstate Biotechnology, Uppsala, Sweden) and analyzed with flow cytometry (BD Biosciences). In Figure 2, the X-axis indicates treatment time, i.e., time after S00109 addition, and the Y-axis indicates the ratio (%) of cells that were phospho-histone-H3-positive. The level of histone H3 phosphorylation (%) after sequential treatment of Jurkat cells with X-ray irradiation (10 Gy) and compound S00109 at 1 μΜ (unfilled squares) and 0.3 μΜ (solid circles) increased with increasing treatment time up to 24 hours.
Example 2: Cytotoxicity of S00109 alone or in combination with radiation
Phosphorylated histone H2AX expression [0117] Expression of phosphorylated histone FI2AX (γΗ2ΑΧ phosphorylated on Seri 39) was measured as an indicator of cytotoxicity, in particular, DNA-damaged-related cytotoxicity. Jurkat cells were irradiated with 10 Gy X-rays and cultured 24 hour in 10% FCS-RPMI as described above. Then, S00109 was added to the culture medium at 1 μΜ for the treatment times up to 24 hours. The cells were lysed in a buffer (100 mM NaCI, 10 mM Tris-HCI (pH 8.0), 1 mM DTT, 0.2% NP-40, 10 mM NaF, 10 mM Na3V04, 500 nM okadaic acid, and proteinase inhibitors). Aliquots of the lysate (30μg protein) were electrophoresed on a 15% SDS page gel and transferred to a membrane for Western blot analysis. Anti-phospho-histone H2AX (Ser 139) Ab (Cell Signaling Technology, Beverly, MA) was used to detectγ-Η2ΑΧ on the blotted membrane. As shown in Figure 3, levels of γΗ2ΑΧ increased treatment time with S00109, indicating that S00109 caused DNA, in addition to DNA damage caused by the irradiation.
Colony formation analysis [0118] The cytotoxic activity of S00109 was further confirmed by colony formation analysis using HCT-116 cells, a human colon cancer cell line, where a decrease in colony counts is a measure of cell growth suppression and/or cell death. HCT-116 human colon cancer cells were cultured in McCoy’s 5A (Invitrogen, Carlsbad, CA) with 10% FCS, 5%C02/air at 37°C. The cells were seeded at 300 cells per 6 well plate in triplicate, irradiated with X rays as shown in the figure legend, and cultured for 24 hours, then treated with S00109 at the indicated dosages and cultured for 8 days. On day 8, colonies were fixed and stained with crystal violet (Sigma-Aldrich), and the number of colonies was counted. Figure 4 shows the effect on S00109 dose (x-axis) on colony numbers (y-axis) counted on day 8.
[0119] Cells that received no radiation ("0 Gy" open circles, solid line in legend of Figure 4) were cultured under the same conditions as the irradiated cells, and were treated with S00109 to show the effects of S00109 alone. Thus, as shown in Figure 4, S00109 alone suppressed colony formation by HCT-116 cells in a dose-dependent manner, indicating that S00109 alone can suppress the growth of cancer cells and/or kill cancer cells at sufficiently high dosage.
[0120] The "normal" colony count for untreated control cells is shown by value for 0 Gy and 0 μΜ S00109.
[0121] Cells that received a radiation dose of 1 Gy (filled circles, dotted line) showed an inhibition of colony formation due to radiation alone. Cells that received a radiation dose of 1 and were exposed to S00109 showed further inhibition of colony formation, indicating that S00109 can augment the cytotoxicity of the radiation treatment. Under these conditions of radiation and . S00109 treatment, a strong dose-dependent additive effect of S00109 was seen.
[0122] Cells that received a radiation dose of 3 Gy ("3 Gy" open square, solid line) shown strong inhibition of colony formation due to radiation alone. S00109 appears to have a detectable additional inhibitory effect at the highest concentration (4 μΜ), again indicating that S00109 can augment the cytotoxicity of radiation treatment.
Example 3: Cytotoxicity of S00109 alone and in combination with dexamethasone.
[0123] Cytotoxicity of S00109 alone and in combination with dexamethasone was measured by identifying the number of cells in subG1 phase after treatment, where subG1 phase indicates cell death, such that he number of cells in subG1 phase after treatment indicates cell killing by the treatment. A human multiple-myeloma-derived cell line, ARH-77, was cultured in the presence or absence of S00109, with or without dexamethasone, for 24 hour in 10% fetal calf serum (FCS)/RPMI1640 at 37 °C with 5% C02/air using materials and conditions described above. Harvested cells were stained with Krishan’s buffer (0.1% sodium citrate, 50 μg/ml propidium iodide, 20 μg/ml RNase A, 0.5% Nonidet P-40) and analyzed with flow cytometry (BD Biosciences, Franklin Lakes, NJ).
[0124] Fig. 5 shows the percentage of ARH-77 cells in subG1 phase (y-axis) after treatment with S00109 (x-axis) alone or in combination with dexamethasone. The ’normal’ percentage ofsubGI cells in a population of untreated control cells is shown by the value for S00109 alone (filled diamonds, solid line, "S109 only" in figure legend) at 0 μg/ml S00109. S00109 treatment alone, at concentrations up to 10 μg/ml, caused cell death in a dose-dependent manner. Dexamethasone treatment alone at 2 ng/ml (open squares, dotted line), 20 ng/ml (open triangles, dot/dash line) and 200 ng/m open circles, dashed line) without S00109 showed slightly increased levels ofsubGI cells, i.e., slightly increased cytotoxicity, compared to the control. However, treatment with S00109 in combination with dexamethasone resulted in a dramatic increase in the levels of subG1 cells. The combination effect showed a strong dependence on the S00109 concentration, demonstrating a dose-dependent effect of S00109. The combination of S00109 and dexamethasone resulted in a level of cell death that was significantly higher than the level seen with either compound alone. Thus, S00109 augmented the cytotoxicity of dexamethasone.
Example 4: Effects of representative compounds of the invention, alone and in combination, on survival of mice with xenografts of ARH-77 cells [0125] Mice with xenografts of ARH-77 (a human multiple-myeloma-derived cell line) were treated with S00109, S01860, S03518, S03405 or S03747 or with dexamethasone, a recognized "standard" treatment, and their survival was measured and compared with survival of vehicle-treated (control) mice with xenografts. The ability of a treatment to prolong survival was considered to be an indicator of the cytotoxicity of the treatment towards the grafted cancer cells, without significant adverse activity on normal (mouse) cells In vivo.
[0126] Male severe combined immune deficiency (SCID) mice at 8 weeks old were transplanted intraperitoneally with 1.9X106 (Fig. 6), 0.8Xl06(Fig. 7), 4.lxl06(Fig. 8), cells/animal of ARH-77 cells (n = 10).
[0127] Animals were housed in accordance with guidelines from the Association for the Assessment and Accreditation of Laboratory Animal Care International, and the protocols were approved by institutional animal care committee of CanBas Co. Ltd.
[0128] For the experiment shown in Figure 6, mice received 1.9X106 ARH-77 cells by intraperitoneal transplantation. Mice treated with S00109 ("S109") received an intraperitoneal injection of 50mg/kg S00109. Mice treated with dexamethasone ("Dexa") received an intraperitoneal injection of 2mg/kg dexamethasone. Vehicle treated control animals received intraperitoneal vehicle injection. Each injection was performed on day 1, day 2 and day 3 after transplantation of ARH-77 cells. Survival (y-axis, % of mice surviving) was measured for up to 80 days after transplantation (x-axis) for control mice treated with vehicle alone ("Control" dashed line); mice treated with 50 mg/kg compound S00109 ("S109" solid line); and mice treated with 2 mg/kg dexamethasone ("Dexa" dot-dash line). Mice treated with S00109 had a significantly longer duration of survival than untreated control mice. Although mice treated with dexamethasone had a longer survival duration than untreated control mice, the therapeutic effect of dexamethasone was much smaller than the therapeutic effect of S00109.
[0129] For the experiment shown in Figure 7, mice received 0.8X 106 ARH-77 cells by intraperitioneal transplantation. Mice were treated by a single oral administration of compounds on Day 1 after transplantation as follows: control mice orally treated with vehicle alone ("Control" solid line); mice orally treated with 750 mg/kg compound S00109 ("S109" dot line); and mice orally treated with 750 mg/kg compound S01860 ("S1860" dash line). Although mice treated with S00109 initially showed slightly lower survival than the control mice, after about 64 days, mice treated with S00109 showed significantly higher survival than control mice, with almost 70% survival at 85 days, compared with only about 20% of the control mice surviving at 85 days. Mice treated with S01860 showed dramatically higher survival rates than control mice or mice treated with S00109, where the first decrease in survival was not seen until 70 days after transplantation, and almost 90% of the S01860-treated mice survived at 85 days.
[0130] For the experiment shown in Figure 8, mice received 4.1 x 106 ARH-77 cells by intraperitoneal transplantation. Mice were treated by once-daily oral administration of compounds on Day 1 and once-daily oral administration of compounds on Day 2 after transplantation as follows: control mice orally treated once daily for two days with vehicle alone ("CONT" solid line); mice orally treated once daily for two days with 250 mg/kg compound S003518 ("S3518" dot line); mice orally treated once daily for two days with 250 mg/kg compound S003405 ("S3405" dash line); and mice orally treated once daily for two days with 250 mg/kg compound S003747 ("S3747" dot-dash line). Mice treated with S03518, S03405 or S03747 all showed dramatically higher survival rates than control mice. Control mice showed decreased survival beginning at about 29 days after transplantation, and only about 30% survival at 50 days after transplantation. In contrast, mice treated with S03518, S03405 or S03747 showed very little decrease in survival, and still had extremely high survival rates of between 80-100% by 50 days after transplantation.
[0131] These results demonstrated that S00109, S01860, S03518, S03405 or S03747, administered intraperitoneally or orally, had selective cytotoxicity in vivo against cancer cells (ARH 77 cells of the xenograft tumor) while having no detectable cytotoxicity against normal cells (the mouse graft host). These results demonstrated that five different compounds of the present invention were administered to a subject in an effective amount to treat a proliferative disorder in a subject.
Example 5: Ability of representative compounds to cause adaptation to G2 cell cycle arrest and induce G2-arrested cells to re-enter the cell cycle [0132] Representative compounds were synthesized according to methods provided herein. The structure and other properties of each compound was determined by 1H NMR spectroscopy for each synthesized compound.
[0133] Pre-arrested Jurkat cells were prepared as described in Example 1. Briefly, Jurkat cells were subjected to X-ray irradiation at a dose of 10 Gy, and cultured for 24 hours in 10% fetal calf serum (FCS)/RPMI1640 at 37°C with 5% C02/air, after which time cells were exposed to various concentrations of test compounds, and cultured under the conditions described above for an additional 24 hours before hamesting. Harvested cells were stained with Krishan’s buffer (0.1% sodium citrate, 50 μg/ml propidium iodide, 20 μg/ml RNase A, 0.5% Nonidet P-40) and analyzed by flow cytometry (BD Biosciences, Franklin Lakes, NJ) to identify the cell stage of each cell in the sample. Cells in G1 phase were identified by having doubled (2N) DNA content.
[0134] The IC50 value for each compound was calculated as the dosage (concentration in μΜ) that caused half-maximal increase of the percentage of cells in G1 phase (the G1 increment) measured forthattest compound.

Example7: Effects of S00109 alone, and S00109 in combination with additional anti-cancertreatments, on normal cells and on cancer cells [0138] The effects of S00109 alone, and S00109 in combination with well-known anti-cancer treatments, was determined for normal human dermal fibroblasts (NHDF), and human umbilical endothelial cells (HUVEC), and for MIAPaCa2 cells (pancreatic cancer-derived cell line), HCT116 cells (colon cancer-derived cell line), IM9 cells (multiple myeloma-derived cell line), ARH-77 cells (multiple myeloma-derived cell line), RPMI-8226 cells (multiple myeloma-derived cell line) and NCI-H929 cells (multiple myeloma-derived cell line).
[0139] Cells were treated as described in Tables 4-11, then harvested, stained with propidium iodide to allow measurement of DNA content, and analyzed by flow cytometry to determine the cell cycle stage of each cell present in each population following treatment. Thus, a "phenotype" or "predominant phenotype" or "cell cycle pattern" is determined on the basis of the percentage of cell in various cell cycle stages (G1, S, G2, M, subG1 (dead), and so on). Tables 4-11 report the predominant cell cycle pattern, or the most relevant change in the cell cycle pattern, corresponding to each treatment combination. For example, the result for one treatment combination may be reported as an increase in the number of cells in G2 phase after exposure to a certain S00109 concentration, compared with the predominant phenotype resulting from exposure to a lower S00109 concentration, for the same anti-cancer treatment. Similar, the result for a anti-cancer treatment, in the absence of S00109 treatment, may be reported as an increase in the number of cells in S phase, compared with the corresponding control (no anti-cancer treatment, no S00109, same culture conditions).
[0140] Normal human cells and human cancer cells were exposed to S00109 (abbreviated S109 in Tables 4-11) at various concentrations from no S00109, up to 100 μΜ S00109, as shown in the header for each column.
[0141] Normal human cells and human cancer cells were exposed to a variety of anti-cancer treatments including X-ray radiation, and the anti-cancer agents ("anti-cancer drugs") methotrexate, CPT-11 (irinotecan, Camptosar®), 5-FU (5-fluorouracil), CDDP (cisplatin), adriamycin, Gemzar® (gemcitabine), taxol, Velcade® (bortezomib), vincristine, dex-amethasone, and melpharan. Treatments included simultaneous treatment with the anti-cancer agent and the indicated dose of S00109, as well as staggered treatment combinations, were cells were treated first with an anti-cancer treatment and then with the indicated dose of S00109. A key to the treatments as described in the legend for each row in Tables 4-11 is presented below.
[0142] Control experiments included experiments in which cells were treated with S109 at the indicated dose, and no additional treatment, indicated as "alone" in Tables 4-11, where "S109 at the indicated dose" includes no S00109, or S00109 at various concentrations up to 100 μΜ, as indicated in each column heading. Control experiments included experiments designed to test the effects of 24 hr and 48 culture times, as well as the effects of additional steps such as a change of culture media at 3 hours, or the addition of S00109 in a later step.

Results [0143] The results show that S00109 had more severe cytotoxic effects on cancer cells and little or no cytotoxic effects on normal cells Alternately expressed, the results show that most cancer cells are more sensitive to S00109 and than are most normal cells These results are in agreement with the results of the ARH-77 xenograft tumor transplant experiments of Example 4, where treatment of xenograft tumor-bearing mice with S00109, S01860, S03518, S03405 or S03747 resulted in dramatic increases in the survival rates of the tumor-bearing mice, indicating that S00109, S01860, S03518, S03405 or S03747 has specifically killed or suppressed the ARH-77 (multiple myeloma) cells in the xenograft tumors without having cytotoxic effects on the normal cells or organs of the mouse host.

Example 8: Synthesis of Representative Compounds [0156] The following examples are intended to serve as illustrations, and all compounds of this invention could be synthesized using methods similar to those described in these examples.
General Procedure for the Synthesis of substituted 2-pyridylhydrzines [0157]
[0158] The general procedure for the synthesis of substituted 2-pyridylhydrazines is represented here in the synthesis of 4-(trifluoromethyl)-6-methyl-2-pyridylhydrazine (14). One equivalent of 2-chloro-4-(trifluoromethyl)-6-methylpyridine (13) and 1.5 equivalent of hydrazine hydrate were mixed in ethanol. The solution turned yellow after being stirred for several minutes. The reaction mixture was refluxed until TLC analysis showed no starting material left. The solvent was then removed under vacuum, and the resulting slurry was extracted with ether three times. The combined ether solution was dried over anhydrous MgS04 and evaporated to afford the crude product, which was then re-crystallized from ethanol to give compound 14.
Synthesis of S00069 [0159]
[0160] The anhydride 15 (1 eq.) was added to a solution of the hydrazine 14 (1 .Ommol) in chloroform and stirred under reflux for 4 hr. The reaction was determined to be completed by TLC (petroleum ether : ethyl acetate = 3:1). The solvent was evaporated and the residue was purified by flash chromatography (petroleum ether : ethyl acetate = 2 : 1) to give the product.
Synthesis of S00084 [0161]
[0162] To a solution of S00069 (35mg, 0.117mmol) in THF (6mL) at 0 °C was added NaH (60% in mineral oil, 8mg, 0.12mmol). The mixture was stirred for 30min, and then Mel (20mg) was added. The reaction mixture was stirred for2h at room temperature, and then poured into the saturated aqueous NH4CI. This was extracted with CHCI3. The organic layer was dried over anhydrous Na2S04. The solvent was removed and the residue was purified by preparative TLC (5:1 petroleum ether/diethyl ether) to afford S00084 (3mg).

The mixture was cooled to 0 °C, trifluoroacetic anhydride (20mmol) was then slowly added to the reaction mixture. It was allowed to warm to room temperature and stirred until the reaction was completed judged by TLC. The reaction was quenched with aqueous Na2S03, stirred for 4h, washed with saturated aqueous NaHC03, and dried over anhydrous MgS04. Column chromatography afforded 1.8g of compound 17 as oil.

The corresponding benzylamine 23 (0.08mol) was added to cone. HCI (40mL). The mixture was cooled to -5 °C by ice and salt with stirring. Then sodium nitrite (5.52g, 0.08mol) dissolved in water (20mL) was added. Stirring was continued for 1 h, and stannous chloride (30g) in cone. HCI (30mL) was added slowly over a period of two hours, while keeping the temperature below 0 °C. The mixture was stirred for another hour after the addition and filtered. The filtered solid was treated with dilute aqueous sodium hydroxide and the then extracted with ether. The ether layer was washed with water, dried over anhydrous Na2S04.

Synthesis of S00513 [0178]
Step 1: 3-Chloro-4-trifluoromethylbenzylbromide 27: [0179] A mixture of 2-chloro-4-methyl-1-trifluoromethylbenzene 26 (0.20g, 1mmol), N-bromosuccinimide (0.17g, 1 mmol) and benzoyl peroxide (7.4mg, 0.03mmol) in carbon tetrachloride (2mL) was heated to reflux for 2 hours. Another portion of benzoyl peroxide (20mg, 0.08mmol) was added. The mixture was heated to reflux for another 0.5 hours. The reaction mixture was further stirred at room temperature for 16 hours. The solid was removed by filtration. The solvent was removed under reduced pressure. The crude product was purified by flash chromatography on silica, using petroleum ether as eluent, to give 0.22g (80%) of Compound 27.
Step 2: Compound S00513 [0180] To a solution of 3,4-dimethylmaleimide 28 (43mg, 0.34mmol) in 1.3mL of acetone was added anhydrous potassium carbonate (50mg, 0.37mmol) and Compound 27 (100mg, 0.37mmol). The reaction mixture was stirred at room temperature overnight. Water was added and the mixture was extracted with ethyl acetate. The organic extract was washed with brine, dried (Na2S04), and concentrated under reduced pressure. The crude product was purified by chromatography on silica, using petroleum ether/ethyl acetate (10:1) as eluent, to give 70mg (60%) of Com pound S00513.
Synthesis of S00628 [0181]
[0182] Into a solution of 1-hydroxy-3,4-dimethylazoline-2,5-dione 30 (56mg, 0.39mmol, 1 equiv) in 1,2-dichloroethane (2.5mL), CuCI (39mg, 0.39mmol, 1 equiv), freshly activated 4 À molecular sieves (~100 mg), and 4-trifluoromethylphe-nylboronic acid 29 (150 mg, 0.78mmol, 2 equiv) were added, followed by pyridine (34mg, 0.43mmol, 1.1 equiv). The resulting light brown suspension was stirred for 16h. The reaction mixture was filtered. Chromatography of the filtrate (petroleum ether/ethyl acetate = 7: 1) afforded Compound S00628 as a white solid (65 mg, 59%).
Example 9: Synthetic procedures [0183] All compounds listed in Tables 1, 2, and 3 were synthesized using methods identical to or similar to those described in the examples below.
General procedure for the synthesis from halide-substituted pyridine analogs to target compounds [0184]
Scheme 1
[0185] Starting material dissolved in ethanol and hydrazine hydrate(10.0eq) was added to form a mixture, the mixture was stirred at 50-60°C(oil temperature) for several hours (completion was checked by TLC), the solvent was evaporated, water was added and the resulting mixture was extracted with ethyl acetate, dried and concentrated to form a crude preparation that was used without further purification for the next step. The crude preparation was dissolved in chloroform (or toluene, acetic acid, or another suitable solvent), anhydride was added (1 .Oeq), the mixture was heated at 50-60°C (oil temperature) for several hours (completion checked by TLC), the solvent was evaporated, and the preparation was purified by Prep-TLC to provide the desired compound.
[0186] The starting materials were commercially available, so the synthetic route of compounds S00585, S01098, S01207 was similar to general procedure.

Scheme 2
Intermediate 1 [0188] 2-Chloro-5-trifluoromethyl-pyridine (10mmol) was dissolved in CH2CI2 (20mL) and UHP (Urea-hydrogen peroxide addition compound, 21 mmol) was added. The mixture was cooled to 0 °C, trifluoroacetic anhydride (20mmol) was then slowly added to the reaction mixture. It was allowed to warm to room temperature and stirred until the reaction was completed monitored by TLC.
