[0353] The compounds of the present disclosure may include one or more asymmetric centers, and thus may exist in a variety of stereoisomeric forms, for example, enantiomers and/or diastereomers. For example, the compounds of the present disclosure may be in the form of an individual enantiomer, diastereomer or geometric isomer (e.g., cis- and trans-isomers), or may be in the form of a mixture of stereoisomers, including racemic mixture and a mixture enriched in one or more stereoisomers. The isomers can be separated from the mixture by the methods known to those skilled in the art, including chiral high pressure liquid chromatography (HPLC) and the formation and crystallization of chiral salts; or alternative isomers can be prepared by asymmetric synthesis.

[0354] It will be understood by those skilled in the art that the organic compounds can form complexes with solvents in which they are reacted or from which they are precipitated or crystallized. These complexes are known as “solvates”. Where the solvent is water, the complex is known as “hydrate”. The present disclosure encompasses all solvates of the compounds of the present disclosure.

[0355] The term “solvate” refers to forms of a compound or a salt thereof, which are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, etc. The compounds described herein can be prepared, for example, in crystalline form, and can be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In some cases, the solvates will be capable of isolation, for example, when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid. “Solvate” includes both solution-phase and isolatable solvates. Representative solvates include hydrates, ethanolates and methanolates.

[0356] The term “hydrate” refers to a compound that is associated with water. Generally, the number of water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, hydrates of a compound can be represented, for example, by a general formula R•x H.sub.2O, wherein R is the compound, and x is a number greater than 0. Given compounds can form more than one type of hydrates, including, for example, monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, for example, hemihydrates (R-0.5 H.sub.2O)) and polyhydrates (x is a number greater than 1, for example, dihydrates (R.2 H.sub.2O) and hexahydrates (R.6 H.sub.2O)).

[0357] Compounds of the present disclosure may be in an amorphous or a crystalline form (polymorph). Furthermore, the compounds of the present disclosure may exist in one or more crystalline forms. Therefore, the present disclosure includes all amorphous or crystalline forms of the compounds of the present disclosure within its scope. The term “polymorph” refers to a crystalline form of a compound (or a salt, hydrate or solvate thereof) in a particular crystal packing arrangement. All polymorphs have the same elemental composition. Different crystalline forms generally have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shapes, optical and electrical properties, stability, and solubility. Recrystallization solvents, rate of crystallization, storage temperatures, and other factors may cause one crystalline form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.

[0358] The present disclosure also comprises compounds that are labeled with isotopes, which are equivalent to those described in formula (I), but one or more atoms are replaced by atoms having an atom mass or mass number that are different from that of atoms that are common in nature. Examples of isotopes which may be introduced into the compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine and chlorine, such as .sup.2H, .sup.3H, .sup.13C, .sup.11C .sup.14C, .sup.15N, .sup.180, .sup.170, .sup.31P, .sup.32P, .sup.35S, .sup.18F and .sup.36Cl, respectively. Compounds of the present disclosure that comprise the above isotopes and/or other isotopes of other atoms, prodrugs thereof and pharmaceutically acceptable salts of said compounds or prodrugs all are within the scope of the present disclosure. Certain isotope-labeled compounds of the present disclosure, such as those incorporating radioactive isotopes (e.g., .sup.3H and .sup.14C), can be used for the measurement of the distribution of drug and/or substrate in tissue. Tritium, which is .sup.3H and carbon-14, which is .sup.14C isotope, are yet alternative, because they are easy to prepare and detect. Furthermore, replaced by heavier isotopes, such as deuterium, which is .sup.2H, may provide therapeutic benefits due to the higher metabolic stability, such as prolonging the half-life in vivo or decreasing the dosage requirements, and thus may be alternative in some cases. Isotope-labeled compounds of formula (I) of the present disclosure and prodrugs thereof can be prepared generally by using readily available isotope-labeled reagents to replace non-isotope-labeled reagents in the following schemes and/or the procedures disclosed in the examples and preparation examples.

[0359] In addition, prodrugs are also included within the context of the present disclosure. The term “prodrug” as used herein refers to a compound that is converted into an active form that has medical effects in vivo by, for example, hydrolysis in blood. Pharmaceutically acceptable prodrugs are described in T. Higuchi and V Stella, Prodrugs as Novel Delivery Systems, A.C.S. Symposium Series, Vol. 14, Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987, and D. Fleisher, S. Ramon and H. Barbra “Improved oral drug delivery: solubility limitations overcome by the use of prodrugs”, Advanced Drug Delivery Reviews (1996) 19(2) 115-130, each of which are incorporated herein by reference.

[0360] The prodrugs are any covalently bonded compounds of the present disclosure, which release the parent compound in vivo when the prodrug is administered to a patient. Prodrugs are typically prepared by modifying functional groups in such a way that the modifications can be cleaved either by routine manipulation or decompose in vivo to yield the parent compound. Prodrugs include, for example, compounds of the present disclosure wherein the hydroxyl, amino or sulfhydryl groups are bonded to any group that, when administered to a patient, cleaves to form the hydroxyl, amino or sulfhydryl groups. Thus, representative examples of prodrugs include (but are not limited to) the acetate/acetamide, formate/formamide and benzoate/benzamide derivatives of the hydroxyl, amino or sulfhydryl functional groups of the compounds of formula (I). Furthermore, in the case of carboxylic acid (-COOH), esters such as methyl esters and ethyl esters, etc. can be employed. The ester itself may be active in their own and/or hydrolyzable under in vivo conditions in the human body. Suitable pharmaceutically acceptable in vivo hydrolysable ester groups include those groups that can readily break down in the human body to release the parent acids or salts thereof.

[0361] The present disclosure also provides a pharmaceutical formulation comprising a therapeutically effective amount of a compound of formula (I), or therapeutically acceptable salts thereof, and pharmaceutically acceptable carriers, diluents or excipients thereof. All of these forms belong to the present disclosure.

Pharmaceutical Compositions, Formulations and Kits

[0362] In another aspect, the present disclosure provides a pharmaceutical composition comprising a compound of the present disclosure (also referred to as the “active ingredient”) and a pharmaceutically acceptable excipient. In certain embodiments, the pharmaceutical composition comprises an effective amount of the compound of the present disclosure. In certain embodiments, the pharmaceutical composition comprises a therapeutically effective amount of the compound of the present disclosure. In certain embodiments, the pharmaceutical composition comprises a prophylactically effective amount of the compound of the present disclosure.

[0363] A pharmaceutically acceptable excipient for use in the present disclosure refers to a non-toxic carrier, adjuvant or vehicle which does not destroy the pharmacological activity of the compound formulated together. Pharmaceutically acceptable carriers, adjuvants, or vehicles that may be used in the compositions of the present disclosure include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins (e.g., human serum albumin), buffer substances (such as phosphate), glycine, sorbic acid, potassium sorbate, a mixture of partial glycerides of saturated plant fatty acids, water, salt or electrolyte (such as protamine sulfate), disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salt, silica gel, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based materials, polyethylene glycol, sodium carboxymethyl cellulose, polyacrylate, wax, polyethylene-polyoxypropylene block polymers, polyethylene glycol and lanolin.

[0364] The present disclosure also includes kits (e.g., pharmaceutical packs). Kits provided may include a compound disclosed herein, other therapeutic agents, and a first and a second containers (e.g., vials, ampoules, bottles, syringes, and/or dispersible packages or other materials) containing the compound disclosed herein or other therapeutic agents. In some embodiments, kits provided can also optionally include a third container containing a pharmaceutically acceptable excipient for diluting or suspending the compound disclosed herein and/or other therapeutic agent. In some embodiments, the compound disclosed herein provided in the first container and the other therapeutic agents provided in the second container is combined to form a unit dosage form.

Administration

[0365] The pharmaceutical composition provided by the present disclosure can be administered by a variety of routes including, but not limited to, oral administration, parenteral administration, inhalation administration, topical administration, rectal administration, nasal administration, oral administration, vaginal administration, administration by implant or other means of administration. For example, parenteral administration as used herein includes subcutaneous administration, intradermal administration, intravenous administration, intramuscular administration, intra-articular administration, intraarterial administration, intrasynovial administration, intrasternal administration, intracerebroventricular administration, intralesional administration, and intracranial injection or infusion techniques.

[0366] Generally, the compounds provided herein are administered in an effective amount. The amount of the compound actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient’s symptoms, and the like.

[0367] When used to prevent the disorder disclosed herein, the compounds provided herein will be administered to a subject at risk for developing the condition, typically on the advice and under the supervision of a physician, at the dosage levels described above. Subjects at risk for developing a particular condition generally include those that have a family history of the condition, or those who have been identified by genetic testing or screening to be particularly susceptible to developing the condition.

[0368] The pharmaceutical compositions provided herein can also be administered chronically (“chronic administration”). Chronic administration refers to administration of a compound or pharmaceutical composition thereof over an extended period of time, e.g., for example, over 3 months, 6 months, 1 year, 2 years, 3 years, 5 years, etc, or may be continued indefinitely, for example, for the rest of the subject’s life. In certain embodiments, the chronic administration is intended to provide a constant level of the compound in the blood, e.g., within the therapeutic window over the extended period of time.

[0369] The pharmaceutical compositions of the present disclosure may be further delivered using a variety of dosing methods. For example, in certain embodiments, the pharmaceutical composition may be given as a bolus, e.g., in order to raise the concentration of the compound in the blood to an effective level. The placement of the bolus dose depends on the systemic levels of the active ingredient desired throughout the body, e.g., an intramuscular or subcutaneous bolus dose allows a slow release of the active ingredient, while a bolus delivered directly to the veins (e.g., through an IV drip) allows a much faster delivery which quickly raises the concentration of the active ingredient in the blood to an effective level. In other embodiments, the pharmaceutical composition may be administered as a continuous infusion, e.g., by IV drip, to provide maintenance of a steady-state concentration of the active ingredient in the subject’s body. Furthermore, in still yet other embodiments, the pharmaceutical composition may be administered as first as a bolus dose, followed by continuous infusion.

[0370] The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, premeasured ampules or syringes of the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the compound is usually a minor component (from about 0.1 to about 50% by weight or alternatively from about 1 to about 40% by weight) with the remainder being various vehicles or excipients and processing aids helpful for forming the desired dosing form.

[0371] With oral dosing, one to five and especially two to four and typically three oral doses per day are representative regimens. Using these dosing patterns, each dose provides from about 0.01 to about 20 mg/kg of the compound provided herein, with alternative doses each providing from about 0.1 to about 10 mg/kg, and especially about 1 to about 5 mg/kg.

[0372] Transdermal doses are generally selected to provide similar or lower blood levels than are achieved using injection doses, generally in an amount ranging from about 0.01 to about 20% by weight, alternatively from about 0.1 to about 20% by weight, alternatively from about 0.1 to about 10% by weight, and still alternatively from about 0.5 to about 15% by weight.

[0373] Injection dose levels range from about 0.1 mg/kg/hour to at least 10 mg/kg/hour, all for from about 1 to about 120 hours and especially 24 to 96 hours. A preloading bolus of from about 0.1 mg/kg to about 10 mg/kg or more may also be administered to achieve adequate steady state levels. The maximum total dose is not expected to exceed about 2 g/day for a 40 to 80 kg human patient.

[0374] Liquid forms suitable for oral administration may include a suitable aqueous or nonaqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like. Solid forms may include, for example, any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

[0375] Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable excipients known in the art. As before, the active compound in such compositions is typically a minor component, often being from about 0.05 to 10% by weight with the remainder being the injectable excipient and the like.

[0376] Transdermal compositions are typically formulated as a topical ointment or cream containing the active ingredient(s). When formulated as an ointment, the active ingredients will typically be combined with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with, for example an oil-in-water cream base. Such transdermal formulations are well-known in the art and generally include additional ingredients to enhance the dermal penetration of stability of the active ingredients or Formulation. All such known transdermal formulations and ingredients are included within the scope provided herein.

[0377] The compounds provided herein can also be administered by a transdermal device. Accordingly, transdermal administration can be accomplished using a patch either of the reservoir or porous membrane type, or of a solid matrix variety.

[0378] The above-described components for orally administrable, injectable or topically administrable compositions are merely representative. Other materials as well as processing techniques and the like are set forth in Part 8 of Remington’s Pharmaceutical Sciences, 17th edition, 1985, Mack Publishing Company, Easton, Pennsylvania, which is incorporated herein by reference.

[0379] The compounds of the present disclosure can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can be found in Remington’s Pharmaceutical Sciences.

[0380] The present disclosure also relates to the pharmaceutically acceptable formulations of a compound of the present disclosure. In one embodiment, the formulation comprises water. In another embodiment, the formulation comprises a cyclodextrin derivative. The most common cyclodextrins are α-, β- and γ- cyclodextrins consisting of 6, 7 and 8 α-1,4-linked glucose units, respectively, optionally comprising one or more substituents on the linked sugar moieties, which include, but are not limited to, methylated, hydroxyalkylated, acylated, and sulfoalkylether substitution. In certain embodiments, the cyclodextrin is a sulfoalkyl ether β-cyclodextrin, e.g., for example, sulfobutyl ether β-cyclodextrin, also known as Captisol. See, e.g., U.S. 5,376,645. In certain embodiments, the formulation comprises hexapropyl-β-cyclodextrin (e.g., 10-50% in water).

Treatment

[0381] As stated herein, it is known that ATR kinase have roles in tumourigenesis as well as numerous other diseases. We have found that the compounds of formula (I) possess potent anti-tumour activity which it is believed is obtained by way of inhibition of ATR kinase.

[0382] The compounds of the present disclosure are of value as anti-tumour agents. Particularly, the compounds of the present disclosure are of value as anti-proliferative, apoptotic and/or anti-invasive agents in the containment and/or treatment of solid and/or liquid tumour disease. Particularly, the compounds of the present disclosure are expected to be useful in the prevention or treatment of those tumours which are sensitive to inhibition of ATR. Further, the compounds of the present disclosure are expected to be useful in the prevention or treatment of those tumours which are mediated alone or in part by ATR. The compounds may thus be used to produce an ATR enzyme inhibitory effect in a warm-blooded animal in need of such treatment.

[0383] As stated herein, inhibitors of ATR kinase should be of therapeutic value for the treatment of proliferative disease such as cancer and in particular solid tumours such as carcinoma and sarcomas and the leukaemias and lymphoid malignancies and in particular for treatment of, for example, cancer of the breast, colorectum, lung (including small cell lung cancer, non-small cell lung cancer and bronchioalveolar cancer) and prostate, and of cancer of the bile duct, bone, bladder, head and neck, kidney, liver, gastrointestinal tissue, oesophagus, ovary, pancreas, skin, testes, thyroid, uterus, cervix and vulva, and of leukaemias [including acute lymphoctic leukaemia (ALL) and chronic myelogenous leukaemia (CML)], multiple myeloma and lymphomas.

[0384] Anti-cancer effects which are accordingly useful in the treatment of cancer in a patient include, but are not limited to, anti-tumour effects, the response rate, the time to disease progression and the survival rate. Anti-tumour effects of a method of treatment of the present disclosure include but are not limited to, inhibition of tumour growth, tumour growth delay, regression of tumour, shrinkage of tumour, increased time to regrowth of tumour on cessation of treatment, slowing of disease progression. Anti-cancer effects include prophylactic treatment as well as treatment of existing disease.

[0385] An ATR kinase inhibitor, or a pharmaceutically acceptable salt thereof, may also be useful for treating patients with cancers, including, but not limited to, haematologic malignancies such as leukaemia, multiple myeloma, lymphomas such as Hodgkins disease, non-Hodgkinslymphomas (including mantle cell lymphoma), and myelodysplastic syndromes, and also solid tumours and their metastases such as breast cancer, lung cancer (non-small cell lung cancer (NSCL), small cell lung cancer (SCLC), squamous cell carcinoma), endometrial cancer, tumours of the central nervous system such as gliomas, dysembryoplastic neuroepithelial tumour, glioblastoma multiforme, mixed gliomas, medulloblastoma, retinoblastoma, neuroblastoma, germinoma and teratoma, cancers of the gastrointestinal tract such as gastric cancer, oesophagal cancer, hepatocellular (liver) carcinoma, cholangiocarcinomas, colon and rectal carcinomas, cancers of the small intestine, pancreatic cancers, cancers of the skin such as melanomas (in particular metastatic melanoma), thyroid cancers, cancers of the head and neck and cancers of the salivary glands, prostate, testis, ovary, cervix, uterus, vulva, bladder, kidney (including renal cell carcinoma, clear cell and renal oncocytoma), squamous cell carcinomas, sarcomas such as osteosarcoma, chondrosarcoma, leiomyosarcoma, soft tissue sarcoma, Ewings sarcoma, gastrointestinal stromal tumour (GIST), Kaposis sarcoma, and paediatric cancers such as rhabdomyosarcomas and neuroblastomas.

[0386] The compounds of the present disclosure and the methods of treatment comprising the administering or use of a ATR kinase inhibitor, or a pharmaceutically acceptable salt thereof, are expected to be particularly useful for the treatment of patients with lung cancer, prostate cancer, melanoma, ovarian cancer, breast cancer, endometrial cancer, kidney cancer, gastric cancer, sarcomas, head and neck cancers, tumours of the central nervous system and their metastases, and also for the treatment of patients with acute myeloid leukaemia.

[0387] The effective dose of the compound of the present disclosure is usually at an average daily dose of 0.01 mg to 50 mg compound/kg of patient weight, alternatively 0.1 mg to 25 mg compound/kg of patient weight, in single or multiple administrations. Generally, the compound of the present disclosure can be administered to the patient who needs this treatment in the daily dose range of about 1 mg to about 3500 mg per patient, alternatively 10 mg to 1000 mg. For example, the daily dose per patient can be 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 500, 600, 700, 800, 900 or 1000 mg. It can be administered once or several times a day, weekly (or several days apart) or on an intermittent schedule. For example, on a weekly basis (e.g. every Monday), the compound can be administered one or more times a day, variably for several weeks, for example 4-10 weeks. Or, the compound may be administered daily for several days (e.g. 2-10 days), and then a few days (e.g. 1-30 days) without administering the compound, repeating the cycle arbitrarily or repeating a given number of times, e.g. 4-10 cycles. For example, the compound of the present disclosure can be administered daily for 5 days, and then interrupted for 9 days, and then administered daily for 5 days, then interrupted for 9 days, and so on, repeating the cycle arbitrarily or repeating 4-10 times in total.

Example 16 Assay of ATR Kinase Activity

[0493] Biotinylated protein derived from p53 (Eurofins, art. No.: 14-952) was phosphorylated with ATR kinase. The amount of phosphorylated protein was determined by time-resolved fluorescence in this assay. The amount of phosphorylated protein was detected by anti-p53-phospho-(serine 15)-K-specific antibody (Cisbio, art. No.: 61GSTDLA) and d2 labeled anti-GST antibody (Cisbio, art. No. 61P08KAE). Before the assay, the following working solutions were formulated as required: 1×reaction buffer (20 mM HEPES PH8.0, 1% glycerol, 0.01% Brij-35), dilution buffer (20 mM HEPES PH8.0, 1% glycerol, 0.01% Brij-35, 5 mM DTT and 1% BSA), stop solution (20 mM HEPES PH8.0, 1% glycerol, 0.01% Brij-35, 250 mM EDTA), detection buffer (50 mM HEPES pH7.0, 150 mM NaCl, 267 mM KF, 0.1% sodium cholate, 0.01% Tween-20, 0.0125% sodium azide). The reagents used above were purchased from Sigma or Invitrogen, except for those whose manufacturers were mentioned.

[0494] Operations were as follows:

[0495] 4× serially diluted compound solutions were prepared with 1× reaction buffer to give 9 compound solutions with different concentrations, and 2.5 .Math.L of the 4× serially diluted compound solutions were added to a 384-well analysis plate (784075, Greiner). 4× p53 substrate working solution (40 nM) was prepared with 1× reaction buffer, and 2.5 .Math.L of the 4× p53 substrate working solution was added to a 384-well analysis plate. 4× ATR/ATRIP working solution (12.8 ng/.Math.L) was prepared with dilution buffer, and 2.5 .Math.L of the 4× pATR/ATRIP working solution was added to a 384-well analysis plate. 4× ATP working solution (2 mM) was prepared with deionized water, and 2.5.Math.L of the 4× ATP working solution was added to a 384-well analysis plate. The plates were incubated at room temperature in dark for 30 minutes. 5 .Math.L of stop solution was added to the 384 analysis plates. Finally, 5 .Math.L of assay mixture (0.084 ng/.Math.L Anti-phospho-p53(ser15)-K and 5 ng/.Math.L Anti-GST-d2) was added to the 384 well analysis plates, and incubated at room temperature overnight. The fluorescence signal was detected with ENVISION (Perkinelmer) instrument (excitation wavelength: 320 nm, emission wavelength: 665 nm and 615 nm). The inhibition rate in each well was calculated by the fluorescence intensity value in each well: ER (Emission Ratio) = (Fluorescence intensity at 665 nm/Fluorescence intensity at 615 nm); inhibition rate = (ER of positive - ER of assay compound)/(ER of positive - ER of negative)×100%. IC.sub.50 values of compounds were calculated by standard software for parameter fitting (GraphPad Prism 6.0).

Example 17 Assay of Cell Proliferation Inhibition In Vitro

[0496] By detecting the effect of compounds on cell activity in vitro in tumor cell lines TOV21G (ovarian cancer) and MV4-11 (leukemia), the inhibitory effect of compounds on cell proliferation was studied in this assay.

[0497] TOV21G cells and MV4-11 cells were purchased from American Type Culture Collection (ATCC).

[0498] TOV21G cells were cultured in MCDB105/M199 medium (containing 15% of FBS), and used for assaying when the cell confluence reached 85% or more. About 1000 cells were inoculated in each well of a 96-well culture plate, and cultured for 24 hours. Different concentrations (0-10 .Math.M) of compounds to be assayed were added to treat the cells. Each group was assayed in triplicate. Blank wells (containing medium only) and control wells (inoculated cells without being treated with drug) were set. Cells were cultured for 120 hours. 40 .Math.L of Cell Titer-Glo solutions (Promega, #G7573) were added to each well, and the cells were incubated with shaking for 20 min in the dark. 100 .Math.L of solution was transferred from each well to a 96-well blank plate (Corning, #3917), and the luminescence value was read by Biotek Synergy H1 multifunctional microplate reader.

[0499] MV-4-11 cells were cultured in IMDM medium (containing 20% of FBS). About 10,000 cells were inoculated in each well of a 96-well culture plate, and treated by adding different concentrations (0-10 .Math.M) of compounds to be assayed. Each group was assayed in triplicate. Blank wells (containing medium only) and control wells (inoculated cells without being treated with drug) were set. Cells were cultured for 120 hours. 40 .Math.L of Cell Titer-Glo solutions were added to each well, and the cells were incubated with shaking for 20 min in the dark. 100 .Math.L of solution was transferred from each well to a 96-well blank plate, and the luminescence value was read by Biotek Synergy H1 multifunctional microplate reader.

[0500] Inhibition rate (%) = 100% × (control well – assay well) / (control well – blank well)

[0501] The results of the proliferation assay show that the assay compounds are effective in the studied human tumor cells, which is reflected by the IC.sub.50 value (IC.sub.50 is an inhibitory concentration at 50% of the maximum effect).
