A carbon atom bonded to four different substituents is called a "chiral center." A compound with one chiral center has two enantiomeric forms of opposite chirality. A mixture of two enantiomeric forms is called a "racemic mixture." A compound with more than one chiral center has two n-1The compound has enantiomeric pairs (where n is the number of chiral centers). Compounds with more than one chiral center can exist as individual diastereomers or as a mixture of diastereomers (called a "diastereomeric mixture"). When one chiral center is present, a stereoisomer can be characterized by the absolute configuration of that chiral center. Absolute configuration refers to the spatial arrangement of the substituents attached to the chiral center. Enantiomers are characterized by the absolute configuration of their chiral centers and are described by the R- and S-sequencing rules of Cahn, Ingold, and Prelog. Conventions regarding stereochemical nomenclature, methods for determining stereochemistry, and methods for separating stereoisomers are well known in the art (see, for example, "Advanced Organic Chemistry," 4th edition, March, Jerry, John Wiley & Sons, New York, 1992). The compounds of the present invention can include these isomers.

[0298] Here, the test compound is a compound described herein, i.e., a compound of the present invention. Typically, the test compound can be tested at several different concentrations, which are selected in part depending on the assay conditions.
[0299] The compounds of the present invention can be used to inhibit cancer cells and are therefore useful in regulating cell proliferation. The compounds of the present invention can also be advantageously used to induce apoptosis in cells.
[0300] In another aspect, the present invention provides pharmaceutical compositions containing the compounds of the present invention, which can be used in various methods of the present invention (e.g., treating cancer), as described in more detail below.
[0301] The pharmaceutical compositions of the present invention can be formulated to suit the intended route of administration. Examples of routes of administration include parenteral (e.g., intravenous), intradermal, subcutaneous, oral (e.g., inhalation), transdermal (topical), transmucosal, and rectal administration. Solutions or suspensions used for parenteral (particularly intravenous), intradermal, or subcutaneous administration may contain the following components: a sterile diluent (e.g., water for injection, saline, fixed oil, polyethylene glycols, glycerin, propylene glycol, or other synthetic solvents), an antibacterial agent (e.g., benzyl alcohol or methylparaben), an antioxidant (e.g., ascorbic acid or sodium bisulfite), a chelating agent (e.g., ethylenediaminetetraacetic acid), a buffer (e.g., acetate, citrate, or phosphate), and an isotonic agent (e.g., sodium chloride or dextrose). Furthermore, the pH can be adjusted with an acid or base (e.g., hydrochloric acid or sodium hydroxide). Parenteral preparations can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.
[0302] Pharmaceutical compositions suitable for injection include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor ELTM (BASF, Parsippany, NJ) or phosphate-buffered saline (PBS). In all cases, the composition must be sterile and fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. The prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents (for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like). In many cases, it will be preferable to include isotonic agents (for example, sugars, polyalcohols such as mannitol or sorbitol, sodium chloride) in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.
[0303] Sterile injectable solutions can be prepared by incorporating the active compound, for example, the compound of the present invention, in the required amount in a suitable solvent with the above-mentioned components alone or in combination, as needed, followed by sterilization by filtration. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle containing the necessary other ingredients from those mentioned above and a dispersion medium. In the case of sterile powders for preparing sterile injectable solutions, the preferred preparation method is vacuum drying and freeze-drying to prepare a powder of the active ingredient and any additional desired ingredients from a previously sterile-filtered solution.
[0304] Oral compositions generally contain an inert diluent or an edible carrier. These may be sealed in gelatin capsules or compressed into tablets. For oral therapeutic purposes, the active compound may be incorporated with excipients and used in the form of tablets, troches, or capsules.
[0305] Oral compositions can also be prepared using a liquid carrier for use as a mouthwash, where the compound in the liquid carrier is applied orally and slurped, expectorated, or swallowed. Pharmaceutically compatible binders and / or adjuvants can be included as part of the composition. Tablets, pills, capsules, troches, etc. can contain any of the following ingredients or compounds of a similar nature: binders (e.g., microcrystalline cellulose, tragacanth, or gelatin), excipients (e.g., starch, lactose), disintegrants (e.g., alginic acid, Primogel, or corn starch), lubricants (e.g., magnesium stearate or sterotates), glidants (e.g., colloidal silicon dioxide), sweeteners (e.g., sucrose, saccharin), or flavoring agents (e.g., peppermint, methyl salicylate, or orange flavoring).
[0306] For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant (e.g., a gas such as carbon dioxide) or nebulizer.
[0307] Systemic administration can also be via transmucosal or transdermal means.For transmucosal or transdermal administration, a penetrant appropriate to the barrier to be permeated is used in the formulation.Such penetrants are generally known in the art, and include, for example, for transmucosal administration, surfactants, bile salts, and fusidic acid derivatives.Transmucosal administration can be achieved by using nasal sprays or suppositories.For transdermal administration, the active compound is generally formulated into ointments, salves, gels, or creams known in the art.
[0308] The compounds of the invention can also be prepared in the form of suppositories (e.g., with conventional suppository bases such as cocoa butter and other glycerides) or retention enemas for rectal delivery.
[0309] In one embodiment, the active compound can be prepared with a carrier that protects the compound against rapid elimination from the body, such as a controlled-release dosage form, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid, can be used. Methods for preparing such dosage forms are readily apparent to those skilled in the art. Materials are also commercially available from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies against viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared by methods known to those skilled in the art, for example, as disclosed in U.S. Pat. No. 4,522,811.
[0310] For ease of administration and uniformity of dosage, it may be more advantageous to formulate oral or parenteral compositions in dosage unit form. As used herein, dosage unit form refers to a physically discrete unit suitable for a single dose for a subject to be treated, each unit containing a predetermined amount of active compound calculated in association with the necessary pharmaceutical carrier to produce the desired therapeutic effect. The specifications for the dosage unit form of the present invention are determined by and directly depend on the unique characteristics of the active compound, the particular therapeutic effect to be achieved, and the limitations inherent in the technology of compounding such active compounds for individual treatment.
[0311] For example, in certain embodiments, a suitable pharmaceutical composition of the present invention is one suitable for oral administration in a unit dose, e.g., a tablet or capsule containing about 1 mg to about 1 g of a compound of the present invention. In other embodiments, a pharmaceutical composition of the present invention is one suitable for intravenous, subcutaneous, or intramuscular injection. A patient may receive, for example, an intravenous, subcutaneous, or intramuscular dose of a compound of the present invention of about 1 μg / kg to about 1 g / kg. Intravenous, subcutaneous, and intramuscular doses may be given by means of bolus injection. Alternatively, the intravenous dose may be given by continuous infusion over a period of time. Alternatively, a patient may receive a daily oral dose approximately equivalent to the daily parenteral dose, with the composition being administered 1 to 4 times per day.
[0312] Preferably, the compounds of the present invention can be administered to mammals, including humans, parenterally, particularly preferably by continuous infusion or rapid intravenous administration.
[0313] In this case, the dosage is appropriately selected depending on various factors such as the patient's body weight and / or age, and / or the severity of symptoms and the administration route. For example, the dosage of the compound of formula (I) for parenteral administration is generally 1 to 10,000 mg / day / m per human body surface area by continuous infusion. 2 The range is preferably 1 to 5000 mg / day / m per human body surface area. 2 and more preferably 10 to 5000 mg / day / m per human body surface area. 2 is.
[0314] Pharmaceutical compositions containing the compounds of the present invention can be used to treat diseases, particularly cancer.
[0315] In one embodiment, the present invention provides a method for inhibiting tumor growth. Such a method comprises administering to a subject (e.g., a mammalian subject) having a tumor a compound of the present invention in an amount effective to inhibit tumor growth. The compound or composition inhibits tumor growth if tumor size is statistically significantly smaller in subjects treated with the compound or composition than in those not treated.
[0316] The inhibitory effect of certain compounds or compositions of the present invention on tumor growth may be characterized by inhibition of binding between eIF4E (eukaryotic translation initiation factor 4E) and eIF4G (eukaryotic translation initiation factor 4G) by m7GTP pull-down assay and proximity ligation assay. Blocking the binding of eIF4E to eIF4G inhibits transcription. The binding of certain compounds to eIF4E has also been observed by NMR measurements.
[0317] The inhibitory effect of a particular compound or composition of the present invention on tumor growth may be characterized by any suitable method known in the art. For example, the effect of the compound or composition on survivin expression may be measured. Compounds or compositions that regulate survivin expression are likely to exhibit an inhibitory effect on tumor growth. Furthermore, as described in detail in the Examples, assays using tumor cell lines (e.g., soft agar assays using SW480 cells) and animal models of tumor growth (e.g., nude mice implanted with tumor cells and Min mouse models) may also be used to evaluate the inhibitory effect of a given compound or composition on tumor growth.Other exemplary animal models or xenografts for tumor growth include breast cancer (Guo et al., Cancer Res. 62:4678-84, 2002; Lu et al., Breast Cancer Res. Treat. 57:183-92, 1999), pancreatic cancer (Bouvet et al., Cancer Res. 62:1534-40, 2002), ovarian tumors (Nilsson et al., Cancer Chemother. Pharmacol. 49:93-100, 2002; Bao et al., Gynecol. Oncol. 78:373-9, 2000), melanoma (Demidem et al., Cancer Res. 61:2294-300, 2001), and colorectal cancer (Brown et al., Dig. Dis. Sci. 45:1578-84, 2000; Tsunoda et al. al., Anticancer Res. 19:1149-52, 1999; Cao et al., CHn. Cancer Res. 5:267-74, 1999; Shawler et al., J. Immunother.

Res. 18:72-85, 2000), and gastric cancer (Takahashi et al., Int. J. Cancer 85:243-7, 2000).
[0318] The compound or composition that inhibits tumor growth can be administered to a tumor-bearing subject via an appropriate route, for example, depending on the tissue in which the tumor remains.Appropriate dosage can be determined using the knowledge and techniques known in the art, as described above.The therapeutic effect of the compound or composition on tumor growth can also be monitored using methods known in the art.Various methods include, for example, colonoscopy, sigmoidoscopy, biopsy, computed tomography, ultrasound, magnetic resonance imaging, and positron emission tomography, and can be used to monitor the progression and / or growth of colorectal cancer.The method for monitoring the progression and / or growth of ovarian cancer includes, for example, ultrasound, computed tomography, magnetic resonance imaging, chest X-ray, laparoscopy, and tissue sampling.
[0319] In a related aspect, the present invention provides methods for treating or preventing cancer. Such methods include administering to a subject in need thereof a compound or composition of the present invention in an amount effective to treat or prevent cancer in the subject. Treating cancer is understood to include reducing or eliminating cancer progression (e.g., cancer growth and metastasis). Preventing cancer is understood to include preventing or delaying the onset of cancer. Various types of cancer can be treated or prevented by the present invention, including, but not limited to, lung cancer, breast cancer, colorectal cancer, gastric cancer, pancreatic cancer, liver cancer, uterine cancer, ovarian cancer, glioma, melanoma, lymphoma, and leukemia. The subject in need of treatment may be a human or non-human primate or other animal suffering from various types of cancer.
[0320] The subject in need of prevention may be a human or non-human primate or other animal at risk of developing cancer. Methods for diagnosing cancer and screening individuals at high risk of cancer are known in the art and can be used in the present invention. For example, colorectal cancer can be diagnosed by fecal occult blood testing, sigmoidoscopy, colonoscopy, air enema, and virtual colonoscopy. Individuals at high risk of colorectal cancer may have one or more risk factors for colorectal cancer, such as a strong family history of colorectal cancer or polyps, a known family history of hereditary colorectal cancer syndromes, a personal history of adenomatous polyps, and a personal history of chronic inflammatory bowel disease.

As described above, methods that can be used to select compounds for their inhibitory effect on tumor (or cancer cell) growth (or proliferation) can also be used. The route of administration, the dosage of a given compound, and the effect of treatment can be determined using knowledge and techniques known in the art. Factors that can be taken into account in such a determination include, for example, the type and stage of the cancer to be treated.
[0322] The compounds of the present invention that are useful in the treatment and prevention of cancer can be administered in combination with other anti-tumor agents.Anti-tumor agents refer to compounds that inhibit tumor growth.

[0325] Further examples of other antineoplastic agents include "growth inhibitory agents," which refer to compounds or compositions that inhibit cell proliferation in vitro and / or in vivo. Thus, growth inhibitory agents can significantly reduce the proportion of cells in S phase. Examples of growth inhibitory agents include agents that block cell cycle progression (at a point other than S phase), such as agents that induce G1 or M-phase arrest. Classical M-phase blockers include vincas (vincristine and vinblastine), Taxol®, and topo II inhibitors, such as doxorubicin, epirubicin, daunorubicin, etoposide, and bleomycin.

[0328] A compound of the present invention administered in combination with an anti-neoplastic agent does not necessarily require that the compound and the anti-neoplastic agent be administered at the same time, and the compound and the agent may be administered separately, so long as they both have an effect on the same cancer cells at a given time.
[0329] For example, the administration mode can be exemplified by: (1) administration of a single preparation obtained by simultaneously compounding the compound of the present invention and the other antineoplastic agent; (2) simultaneous administration of two preparations obtained by separately compounding the compound of the present invention and the other antineoplastic agent via the same administration route; (3) administration of two preparations obtained by separately compounding the compound of the present invention and the other antineoplastic agent via the same administration route at intervals; (4) simultaneous administration of two preparations obtained by separately compounding the compound of the present invention and the other antineoplastic agent via different administration routes; (5) administration of two preparations obtained by separately compounding the compound of the present invention and the other antineoplastic agent via different administration routes at intervals (e.g., administration of the compound of the present invention followed by the other antineoplastic agent, or administration in the reverse order). The amount of the other antineoplastic agent to be administered can be appropriately selected based on the dosage used in clinical practice. The mixing ratio of the compound of the present invention and the other antineoplastic agent can be appropriately selected depending on the subject, administration route, disease to be treated, symptoms, combination, etc.
[0330] In a further related aspect, the present invention provides methods for promoting apoptosis in cancer cells. Such methods comprise contacting cancer cells with a compound of the present invention in an amount effective to promote apoptosis in those cells. A compound promotes apoptosis if the number of cancer cells undergoing apoptosis is statistically significantly greater in the presence of the compound than in the absence of the compound. Such compounds can be identified by methods known in the art (e.g., measuring caspase activity and / or cell death) using cultured cancer cell lines, xenografts, or animal cancer models. Preferably, the compound is more active in promoting apoptosis in cancer cells than in normal cells. Cancer cells of various tissue origins are treatable by the present invention.
