Description

FP1400 DESCRIPTION Title of Invention S)-N-Benzyl[(4-hydroxyphenyl)methyl]-4,7-dioxo({6-[3-(piperazin yl)azetidinyl]pyridinyl}methyl)(propenyl)-octahydro-1H-pyrazino[2,1- c][1,2,4]triazinecarboxamide compound Technical Field The present invention relates to a (6S,9aS)-N-benzyl[(4- hydroxyphenyl)methyl]-4,7-dioxo({6-[3-(piperazinyl)azetidinyl]pyridin yl}methyl)(propenyl)-octahydro-1H-pyrazino[2,1-c][1,2,4]triazinecarboxamide compound.
Background Art A Wnt signaling pathway is conserved regardless of the difference in the species of organisms, and is known as an important pathway involved in the development, differentiation and maintenance of living organisms. In recent years, however, it is reported that the constitutive activation of the pathway is involved in the development of malignant ormation of fibrosis and cancer. It is known that, particularly in colorectal cancer, melanoma, endometrial cancer, liver cancer and prostate cancer, the Wnt signaling y can be activated constitutively by the suppressible mutation of adenomatous polyposis coli (APC) or activating mutation of nin or the like. It is also known that, in pancreatic cancer, hematological cancer, liver cancer and the like, the Wnt signaling pathway can be activated after the treatment with a known anti-tumor agent.
In Non Patent Literatures 1 and 2, it is described that an excellent anti-tumor ty can be achieved by inhibiting the Wnt signaling pathway. In Non Patent Literatures 12, 13 and 14, it is bed that an excellent effect on fibrosis can be achieved by inhibiting the Wnt signaling pathway. Thus, the Wnt signaling pathway has attracted attention as a novel target for the treatment of tumors or the treatment of is.
In Non Patent Literatures 3, 4, 5, 6, 7, 8, 9, 10 and 11, compounds or antibodies capable of ting the Wnt signaling pathways are sed, and it is reported that the compounds or the dies can act on ase, Traf2- and Nck-interacting kinase (TNIK), Porcupine, Frizzled or and the like.
Furthermore, compounds each having an octahydro-1H-pyrazino[2,1- c][1,2,4]triazine backbone are known as modulator of the Wnt signaling pathway, and the relationship between the compounds and diseases such as cancer and fibrosis is pointed out FP1400 (Patent Literatures 1 to 3).

(invitrogen) was cleaved with restriction enzymes BglII and NotI, and an adapter BEHKS having a sequence shown below (containing restriction enzyme sites BglII, EcoRI, HindIII, KpnI, SacI and NotI) was inserted thereinto, thereby producing a plasmid pNeo-HKS.
BEHKS-F 5'-gatctgaattcaagcttctcgagggtacctctagagagctcgc-3' (SEQ ID NO: 1) BEHKS-R 5'-ggccgcgagctctctagaggtaccctcgagaagcttgaattca-3' (SEQ ID NO: 2) Subsequently, a fragment having a length of about 2700 bp (containing a Wntresponsive sequence and a luciferase gene), which was prepared by cleaving from a TOPglow plasmid contained in a TOPglow/FOPglow TCF Reporter Kit (upstate Catalog#17-366) with restriction enzymes HindIII and KpnI, was inserted between HindIII and KpnI in pNeo-HKS, thereby ing a plasmid pNeo-TOP. The d pNeo-TOP was introduced into human fetus-derived renal cell strain HEK293, then a nd was selected using G418, and then a cell clone strain was established by a limiting dilution method. The cell clone strain was subjected to a Wnt signal detection test.
The cell clone strain was subcultured in a D-MEM glucose-rich culture medium (Wako Pure Chemical ries, Ltd.) containing 10% FBS, and cells in a growth phase were used in the test. Cells were collected using trypsin-EDTA, the number of the cells was d, and then the cells were suspended in a D-MEM glucose-rich culture medium ning 10% FBS so that the number of cells became 2 × 105 cells/mL. The cell suspension was added to a 96-well cell culture plate (Greiner Bio-One Co., Ltd., t number: 655083) in an amount of 0.1 mL/well and then cultured overnight in a 5% CO2 incubator (37C). After the culturing, a substance to be , which was ved in DMSO, was diluted with a D-MEM glucose-rich culture medium containing 10% of FBS and 80 mM of LiCl to produce a sample solution. The sample solution (0.1 mL) was added to each well and then cultured in a 5% CO2 incubator (37C) overnight. Six hours after the FP1400 addition of the sample solution, a supernatant was removed from each well, and then 50 μL of Bright-GloTM Luciferase substrate (Promega, product number: E2620) was added thereto.
The plate was put on a plate mixer for several seconds, and then the on of light from each well was measured using a EnVisionTM abel plate reader (PerkinElmer Co., Ltd.).
The Wnt signal activation rate (%) of each well was determined, and a concentration (IC50) which is required for inhibiting the Wnt signal activity of a substance of interest by 50% was calculated, wherein the luminosity of a well to which a sample solution was not added and LiCl was added was defined as a 100% Wnt signal activity and the luminosity of a well to which either of a sample solution or LiCl was not added was defined as a 0% Wnt signal activity. From the results of the test, it was demonstrated that the compound according to the present invention ted a Wnt signal and was applicable as a therapeutic agent for diseases including cancer and fibrosis.
Test e 2: Evaluation of metabolic stability A test substance was dissolved in DMSO so that the concentration of the resultant solution became 20 mM, and the solution was diluted with DMSO so that the concentration of the resultant solution became 1 mM. The metabolic stability of the test substance was evaluated using a human liver microsome (HLM) in which human liver was pooled. An assay buffer solution contained 0.2 mg/mL of HLM, a 0.1 M of phosphate potassium buffer solution (pH 7.4), 0.1 mM of EDTA, 0.33 mM of NADP+, 8 mM of glucosephosphate, 0.1 U/ mL of glucosephosphate dehydrogenase, 6mM of MgCl2, 0.1 μM of a test substance (final tration in DMSO: 0.01%) in 0.15 mL of the final tion volume.
Fifteen minutes after the initiation of the reaction at 37C, 0.15 mL of a itrile/methanol mixed solution (7 : 3, by ) was added to the solution to terminate the reaction. After centrifugation, the resultant supernatant was analyzed by LC-MSMS, peak areas were compared under the presence or absence of the production of NADPH, and the residual ratio of the test substance was calculated.
Test Example 3: Evaluation of solubility To 0.25 mL of a test solution a mentioned below was added 2.5 μL of a DMSO solution having a compound concentration of 20 mM. The resultant solution was shaken at room temperature for about 15 minutes (the conditions for the shaking are mentioned below).
Subsequently, a atant was collected by a suction filtration under a d pressure.
A DMSO solution having a compound concentration of 200 μM was used as a standard solution, and the concentration of a compound in a te which was quantified by a HPLC- FP1400 UV method was employed as a solubility (rounded off to the whole number). In this evaluation, since a value 200 μM became the upper limit operationally, all of fication values greater than 200 μM were regarded as 200 μM.

[Table 5] es Solubility 124 mM or more 26 42 mM or more and less than 62 mM Test Example 6: Effect of regressing small intestinal polyps in APCMin/+ mouse An APC gene (an adenomatous polyposis coli gene), a Wnt signal ation regulation factor, is called ectal cancer suppressor gene” and is a causal gene of familial adenomatous polyposis. If a mutation occurs in the APC gene, a ctal mucosal cell begins to proliferate disorderly to form colorectal polyps that can be called a precancerous lesion. Thus, it is known that the gene has an important role in the initial stage of a process of onset of ctal cancer.
In a mouse in which the APC gene is mutated (a APCMin/+ mouse), many polyps are developed in the intestinal tract like a familial adenomatous polyposis patient. ore, the mouse is useful for the clarification of the mechanism of the onset or invasion of cancer based on a WNT signal, and is a standard model that has been used for the studies on the prevention, diagnosis and treatment of colorectal cancer.
APCMin/+ mice (C57BL/6J-APC<Min>/J Hetero, female, Sunplanet Co., Ltd.) were grouped so that the average of the body weights of mice in a group became almost the same as one r at the first day of the stration. An analyte was prepared by being dissolved a test substance (Example compound) in 0.1 N HCl so that the concentration became a desired administration concentration, and then stored in a refrigerator at 4C. To a control (vehicle) group, an administration solvent was administered orally under the same FP1400 conditions as a test al. The analyte was continuously administered through an oral route at dosages of 50 mg/kg and 75 mg/kg two times daily for 4 days, and the following three days were provided as drug holidays. This procedure was defined as one cycle, and the administration was performed for 16 days in total (i.e., 4 days × 4 cycles). The experiment was carried out on 6 to 7 mice per group. With respect to each of the control group and the test nce-administered group, the value of the body weight on the final day to the body weight on the first day (i.e., a relative body : RBW) was calculated.
A test substance-administered group of which the (RBW of the test substance-administered group)/(RBW of the control group) was 0.8 or more was determined as a group that could be administered safely. With respect to the test substance-administered group, the actual number of polyps after the administration of the test nce and the standard error of the actual number compared with the number of polyps in the control on the final day (i.e., the 25th day counted from the first day of the administration) are shown in Figure 1. In this test, polyps formed in the small intestine and the colon were counted. A statistical analysis tt's test) of the test substance-administered group relative to the control group was d out, and a P value was ed.
Test Example 7: umor effect in human K562 subcutaneous transplantation model A ation of a human chronic myologenous leukemia cell strain K562 (which had been cultured in a RPMI-1640 liquid e medium supplemented with 10% FBS and penicillin/streptomycin) which was so prepared with PBS (Wako Pure Chemical Industries, Ltd.; Cat# 045-29795) that the density became 2 × 108 cells/mL was mixed with MATRIGEL (BD Biosicence, Cat#: 354234) at a mixing ratio of 1 : 1, thereby preparing a cell suspension having a density of 1 × 108 cells/mL. The resulting cell suspension was transplanted subcutaneously into the right flank of each of six-week-old nude mice (CAnN.Cg-Foxn1nu/CrlCrlj, female, Charles River Laboratories Japan) at a dose of 100 μL.
Seven days after the transplantation, the shorter diameter and the longer diameter of a tumor were measured using an electronic digital caliper (Digimatic TM Caliper, Mitutoyo Corporation) to calculate the tumor volume in accordance with the following equation.
Tumor volume (mm3) = (longer diameter (mm)) × (shorter diameter (mm)) × (shorter diameter (mm))/2 The mice were grouped in such a manner that the e value of the tumor volumes in mice in a group, which were determined on the basis of the tumor volume on the FP1400 first day of the administration. An analyte was prepared by being dissolved a Example compound in 0.1 N HCl so that the dose amount became 10 mL/kg. A Dasatinib administration solution was prepared by dissolving Dasatinib, Free Base (LC Laboratories, Cat. No: D-3307) in a 1 : 1 solution of Otsuka distilled water (Otsuka Pharmaceutical Co., Ltd., Cat#: 1324) and PROPYLENE GLYCOL (Wako Pure Chemical Industries, Ltd., Cat#: 164-04996) so that the dosage amount became 10 mL/kg. A Example compound was administered orally continuously for 5 days starting from the first day of the administration in two d doses daily (bid). Dasatinib was administered orally once daily (qd) for 5 days continuously, and the following two-day drug holidays was set. This procedure was defined as one cycle, and the administration was performed in two cycles in total. A l group was a group to which any example compound was not stered. In the experiment, one group includes 9 to 10 mice. With respect to the control group, a group to which only a Example nd was administered, a group to which only Dasatinib was administered, and an a group to which both a Example compound and nib were administered (hereinafter referred as ‘combined administered group’), the tumor volumes and body weights were measured over time for a period from the first day to the 28th day.
With respect to the control group and the group to which only the Example compound was administered, the measurement was carried out for a period from the first day to the 11th day.
In every measurement, a tumor volume (a relative tumor volume: RTV) and a body weight (a relative body weight: RBW) were calculated ve to the values for the first day, and graphs determined for a period from the first day of the administration to the 28th day are shown in Figs. 2 and 3. Further, a statistic analysis tt's test) was carried out on the group to which both the e compound and Dasatinib were administered compared with the group to which only Dasatinib was administered using a RTV value on day 28, and a group of which the P value was 0.05 or less was marked with an asterisk (*). Further, the number of duals in which a tumor was not observed by visual judgment and was able (i.e., having a non-palpable tumor) on day 28 are also shown in Table 6. At this time, a statistic analysis (Fisher's test) was carried out on the group to which both the Example compound and Dasatinib were administered compared with the group to which only Dasatinib was stered, and a group of which P value was 0.05 or less was marked with an asterisk (*) and a group in which P value is 0.01 or less was marked with asterisks (***).
