The obtained residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate) to obtain 4-bromo-2-cyano-N-((1S,2R)-2-(6-fluoro-2,3-dimethylphenyl)-1-(5-oxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)propyl)benzenesulfonamide (386 mg).

Step 3

The reaction solution was slowly added to hydrochloric acid (1 M, 15 mL) in an ice bath and then extracted with ethyl acetate (15 mL). The organic layer was washed with saturated saline (20 mL), dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate) to give the title compound.

TEST EXAMPLE

(729) The compound according to the present invention was evaluated using the following test method.

Test Example 1 Human RNR Inhibition Effect

(730) The inhibitory activity against the ribonucleotide reduction reaction (hereinafter referred to as RNR reaction) of the test compound was determined by measuring the formation of deoxycytidine diphosphate (hereinafter referred to as dCDP) from cytidine diphosphate (hereinafter referred to as CDP) by the following method.

(731) Human M1 subunit and human M2 subunit (mutant lacking amino terminal 59 amino acids), which are fused a histidine tag at the amino terminus, are overexpressed in Escherichia coli and are solubilized after collection, and histidine tagged human M1 and M2 proteins were purified on a nickel chelate column.

(732) For measuring the inhibitory activity of the test compound against the RNR reaction, the method described in the document [CANCER RESEARCH 64, 1-6, 2004] was referred to.

(733) First, test compounds were serially diluted with DMSO. Next, human M1 protein and human M2 protein were added to an aqueous albumin solution derived from 0.02% fetal bovine serum, a DMSO solution of the compound of the present invention or the control DMSO solution (final concentration of DMSO was 1%) was added, and the mixture was allowed to stand for 20 minutes. Thereafter, the reaction buffer [50 mM HEPES buffer (pH 7.2) at the final concentration, 4 mM magnesium acetate at the final concentration, 100 mM potassium chloride at the final concentration, 6 mM dithiothreitol at the final concentration, 2 mM adenosine triphosphate at the final concentration, 0.24 mM nicotinamide adenine dinucleotide phosphate at final concentration] and 10 μM CDP at the final concentration were added and incubated at 37° C. for 30 minutes to perform RNR reaction. Immediately after the reaction, the reaction was stopped by heating at 100° C. for 15 minutes, followed by centrifugation at 10,000 rpm for 10 minutes. After the centrifugation, a portion (5 μL) of the resulting supernatant was analyzed with a high performance liquid chromatography (Shimadzu Corporation, Prominence) using Shim-pack XR-ODS (manufactured by Shimadzu GLC Co., 3.0×100 mm). Elution was carried out at a measurement wavelength of 265 nm at a flow rate of 0.5 mL/min by a 9-minute concentration gradient from the 12:13 mixture of mobile phase A (10 mM potassium dihydrogen phosphate (pH 6.7), 10 mM tetrabutylammonium, 0.25% methanol) and mobile phase B (50 mM potassium dihydrogen phosphate (pH 6.7), 5.6 mM tetrabutylammonium, 30% methanol) to the same 2:3 mixture to measure the substrate CDP (RT 5.9 min) and the reaction product dCDP (RT 6.2 min).

(734) The inhibitory activity of the test compound was determined by the following equation, and the concentrations of test compounds inhibiting the RNR reaction by 50% are shown as IC.sub.50 (μM) in Tables 19-1 to 19-3.

(735) $\begin{array}{cc}\mathrm{Inhibition}\mathrm{rate}\left(\%\right)=\left(1-\frac{\begin{array}{c}\begin{array}{c}\mathrm{Amount}\mathrm{of}\mathrm{produced}\mathrm{dCDP}\\ \mathrm{where}\mathrm{test}\mathrm{compound}\mathrm{added}\end{array}\\ \left(\mathrm{pmol}\right)\end{array}}{\begin{array}{c}\mathrm{Amount}\mathrm{of}\mathrm{produced}\mathrm{dCDP}\mathrm{of}\mathrm{control}\\ \left(\mathrm{pmol}\right)\end{array}}\right)\times 100& \left[\mathrm{Mathematical}\mathrm{Formula}1\right]\end{array}$

(736) As a result, it is apparent from the following table that the compound of the present invention has an excellent RNR inhibitory action. In contrast, the compound of Comparative Example 1 had an IC.sub.50 of 43 μM, and showed no inhibitory activity against RNR as found in the example compounds of the present invention.

Test Example 2 Cell Proliferation Inhibitory Effect on Human Breast Cancer Cell Line

(740) Human derived breast cancer cell line HCC 1806 cells were daily passaged at a cell density not exceeding 80% in ATCC recommended Roswell Park Memorial Institute medium (RPMI-1640) containing 10% fetal bovine serum (FBS). In order to start the test of cell proliferation inhibitory activity, HCC 1806 cells were suspended in the above medium, after seeing at 180 μl in each well of a 96-well flat bottom plate so that the number of cells per well was 2,000, the cells were cultured at 37° C. for 1 day in an incubator containing 5% carbon dioxide gas. On the next day, the test compound was dissolved in DMSO, and 20 μl of a drug additive solution diluted serially with distilled water to 10 times of the final concentration was added to each well of the culture plate of the cells, and the cells were cultured at 37° C. for 72 hours in an incubator containing 5% carbon dioxide gas. After culturing for 72 hours, 20 μl of glutaraldehyde was added to each well and allowed to stand for 30 minutes, then the plate was washed 10 times with water and was dried. 100 μl of a stain solution (0.05% crystal violet in a 20% methanol solution) was added to each well and allowed to stand for 30 minutes, then the plate was washed 10 times with water and was dried. 100 μL of an extract solution (0.1 N NaH.sub.2PO.sub.4: 100% ethanol=1:1) was added to each well and mixed, and the mixture was measured at a wavelength of 540 nm using a plate reader (MTP-450 manufactured by Corona Electric Co., Ltd.). The growth inhibition rate was calculated from the following formula, and the concentration (IC.sub.50 (μM)) of a test compound inhibiting 50% was determined. The results are shown in Table 20.
Growth inhibition rate (%)={(C−B)−(T−B)}/(C−B)×100

(741) T: Absorbance of well to which test compound was added

(742) C: Absorbance of wells to which no test compound was added

(743) B: Absorbance of wells to which no cell suspension was added

Test Example 4 Evaluation of Antitumor Effect Using Human-Derived Blood Cancer Cell Line (MV-4-11) Subcutaneous Transplantation Model (In Vivo)

(749) A human-derived blood cancer cell line MV-4-11 was transplanted subcutaneously into a nude mouse, and at the time when the tumor volume of the nude mouse on which the engrafted tumor reached about 100 to 300 mm.sup.3, five mice were assigned to each group by random stratification so that the average of the tumor volumes of each group was uniform (day 0), and the compound of the present invention was orally administered daily at 100 mg/kg/day once per day for 14 days. Mouse were killed during the experiments when they lost more than 20% weight based on ethical guidelines, and the final results are calculated based on each group consisting of four mice.

(750) In order to compare the chronological transition of proliferation of tumor for the administration of each test compound, relative tumor volume (RTV) setting the tumor volume at the time of grouping as 1 as the tumor proliferation rate was calculated according to the following formula, and the transition of the average value of RTV of each individual are shown in FIGS. 1 to 4.
RTV=(tumor volume at the day of tumor volume measurement)/(tumor volume at the time of the grouping)

(751) The average RTV value of the compound-administered group of the present invention on the final evaluation day is smaller than the average RTV value of the control group, and when a statistically significant difference (Student-t test) is shown, the compound of the present invention was determined to be significantly effective, and the statically significant difference is marked with * in the figure (*: p<0.05).

(752) As a result, it was revealed that the compound of the present invention shows a significant antitumor effect.
