1. Field of the Invention
The present invention relates to novel compounds which are effective for prevention and treatment of various diseases associated with abnormal angiogenesis, and to medical compositions such as angiogenesis inhibitors and antitumor agents comprising the novel compounds.
2. Related Background of the Invention
Angiogenesis is an essential biological phenomenon for fetal vascular formation and morphological and functional development of organs. New blood vessels are assembled through several processes including endothelial cell migration, proliferation and tube formation, and the participation of mast cells, lymphocytes, interstitial cells and the like has been shown to be important in this process (J. Folkman and Y. Shing, J. Biol. Chem., 267, 10931, 1992). In adult individuals, physiological angiogenesis occurs during the female estrous cycle, but pathological increase in angiogenesis in adult individuals is known to be connected with onset or progression of various diseases. Specific diseases associated with abnormal angiogenesis include cancer, rheumatoid arthritis, atherosclerosis, diabetic retinopathy, angioma, psoriasis, and the like (J. Folkman, N. Engl. J. Med., 333, 1757, 1995). In particular, the literature has indicated angiogenesis dependency for solid tumor growth, and angiogenesis inhibitors are therefore promising as new therapeutic agents for intractable solid tumors (J. Folkman, J. Natl. Cancer Inst., 82, 4, 1990).
The prior art includes compounds based on a urea structure, described in WO99/00357 and WO00/43366. WO99/00357 mentions biphenylurea derivatives which have an inhibiting action on raf kinase and an antitumor effect, but their angiogenesis-inhibiting effect is not disclosed. WO00/43366 describes quinoline derivatives and quinazoline derivatives which exhibit a weak karyomorphism-altering effect on A375 human melanoma cells in vitro and an antiproliferative effect on endothelial cells stimulated by vascular epithelial growth factor (VEGF), and which thus have an antitumor effect, but their effect on angiogenic factors other than VEGF is not disclosed.
As mentioned above, it is ardently desired to provide angiogenesis-inhibiting compounds which are useful as drugs. However, clinically effective compounds that exhibit excellent angiogenesis-inhibiting effects and high usefulness as medicines have not yet been discovered.
It is an object of the present invention to investigate and discover angiogenesis-inhibiting compounds which (1) exhibit antitumor activity through a powerful angiogenesis-inhibiting effect or a powerful angiogenesis-inhibiting and cancer cells growth-inhibiting effect, (2) are highly useful as drug materials in terms of their properties, biokinetics and safety, and (3) are useful for amelioration, prevention and treatment of various diseases associated with abnormal increase in angiogenesis.
As a result of much diligent research in light of the circumstances described above, the present inventors have succeeded in synthesizing novel compounds represented by the following general formula (I) and their salts or hydrates, and have completed the present invention upon discovering that the compounds of general formula (I) and their salts or hydrates exhibit an excellent angiogenesis-inhibiting effect.

The compounds of the invention exhibit powerful in vitro inhibition of 1) invasive tube formation by vascular endothelial cells induced by a combination of angiogenic factors, 2) tube formation by vascular endothelial cells specifically induced by single angiogenic factors, and 3) receptor kinases for various angiogenic factors. Among these compound groups having such activity there were also found compounds that inhibit proliferation of cancer cells. Invasion and tube formation by endothelial cells are an important process in angiogenesis, and therefore compounds with inhibiting action against them exhibit angiogenesis-inhibiting effects. In addition, angiogenesis in the body is known to depend not on a single angiogenic factor but rather on the additive and synergistic effect of multiple angiogenic factors ((1) Koolwijk P, van Erck M G M, de Vree W J A, Vermeer M A, Weich H A, Hane maaijer R, van Hinsbergh V W M. Cooperative effect of TNF-alpha, bFGF and VEGF on the formation of tubular structures of human microvascular endothelial cells in a fibrin matrix. Role of urokinase activity. J. Cell Biol. 1996, 132, P1177-1188.; (2) Tallquist M D, Soriano P, Klinghoffer R A. Growth factor signaling pathways in vascular development. Oncogene 1999, 18, P7917-7932.). Thus, the compounds of the invention which inhibit tube formation induced by multiple angiogenic factors produced by cancer cells and the like are expected to exhibit powerful angiogenesis inhibition in vivo, and should be highly useful as angiogenesis inhibitors.
The biochemical activity of the compounds of the invention and their function and effect as medicines (angiogenesis-inhibiting activity, antitumor activity, etc.) may be evaluated by the methods described below.
The following is a list of abbreviations used in the pharmacological test examples described below.
Human Umbilical Vein Endothelial Cells (HUVECs) were isolated according to a reported method (Shinseikagaku Jikken Koza [New Biochemistry Experiment Lectures], “Saibo Baiyo Gijutsu” [Cell Culturing Techniques], p. 197-202), and were cultured in a 5% CO2 incubator (37° C.) using EGM-2 medium (purchased from Clonetics Corp.) until the cells reached confluency. After adding 0.4 ml of bovine fibrinogen (purchased from Sigma Co.) to the inner well of a Transwell culturing plate (purchased from Coster Inc.), it was hardened with 0.7 units/ml of thrombin (purchased from Sigma Co.). The HUVECs were recovered using trypsin-EDTA and then suspended in human endothelial serum free mediumbasal growth medium (hereinafter abbreviated as SFM, purchased from GIBCO BRL), and 0.4 ml of the cell suspension (1.4×105 cells) was seeded onto the hardened fibrin gel and cultured for approximately 4 hours in a 5% CO2 incubator (37° C.). After 4 hours, there was added to the outer chamber of the Transwell 1.5 ml of an SFM solution containing a mixture of angiogenic factors {10 ng/ml EGF (purchased from GIBCO BRL), 30 ng/ml FGF2 (purchased from GIBCO BRL), 75 ng/ml VEGF (purchased from Wako Pure Chemical Industries Co., Ltd.), 50 ng/ml HGF (purchased from R&D Co.) and 7.5 ng/ml TNF-α (purchased from Genzyme Corp.) [The concentrations of the angiogenic factors differed slightly according to the HUVEC lot.]} and a diluted test substance, and culturing was carried out in a 5% CO2 incubator (37° C.). On the 2nd and 4th days after adding the test substance, the medium was exchanged with 1.5 ml of freshly prepared SFM solution containing the angiogenic factor mixture and test substance. Upon aspirating off the culture supernatant in the inner well on the 6th day after the initial addition of the test substance, 0.4 ml of a 3.3 mg/ml MTT solution dissolved in PBS (purchased from Sigma Corp.) was added and culturing was performed for approximately 1 hour in a 5% CO2 incubator (37° C.). The number of tubes formed in the fibrin gel stained with MTT was scored based on microscope observation. Specifically, the number of tubes formed in the absence of the test substance was designated as +++, while − was assigned if absolutely no tubes formed. The number of tubes formed in the presence of the test substance was scored on the 5-level scale of +++, ++, +, +/−, − to evaluate the strength of inhibition of the test substance.
Human Umbilical Vein Endothelial Cells (HUVECs) were isolated by the same method as in Pharmacological Test Example 1, and were cultured in a 5% CO2 incubator (37° C.) using EGM-2 medium (purchased from Clonetics Corp.) until the cells reached confluency.
An ice-cooled mixture of collagen:5×RPMI 1640:reconstitution buffer (all purchased from Nitta Gelatin, Inc.) at 7:2:1 was dispensed at 0.4 ml into each well of a 24-well plate, and then stationed for 40 minutes in a 5% CO2 incubator (37° C.) for gelling. The HUVECs were recovered using trypsin-EDTA and then suspended in human endothelial serum free medium (SFM, purchased from GIBCO BRL) containing added angiogenic factors [20 ng/ml FGF2 (purchased from GIBCO BRL) and 10 ng/ml EGF (purchased from GIBCO BRL), or 25 ng/ml VEGF (purchased from Wako Pure Chemical Industries Co., Ltd.) and 10 ng/ml EGF, or 30 ng/ml HGF (purchased from R&D Co.) and 10 ng/ml EGF], and the cell suspension was added at 0.4 ml to each well (with the cell counts differing slightly according to the HUVEC lot), and cultured overnight in a 5% CO2 incubator (37° C.). On the following day, the medium on the upper layer was aspirated off, and then 0.4 ml of an ice-cooled mixture of collagen:5×RPMI 1640:reconstitution buffer (all purchased from Nitta Gelatin, Inc.) at 7:2:1 was superposed into each well prior to stationing for 4 hours in a 5% CO2 incubator (37° C.) for gelling. After adding 1.5 ml of an SFM solution containing each of the aforementioned angiogenic factors and a diluted test substance onto the upper layer, culturing was performed in a 5% CO2 incubator (37° C.). Upon aspirating off the culture supernatant in each well on the 4th day after addition of the test substance, 0.4 ml of a 3.3 mg/ml MTT solution dissolved in PBS (purchased from Sigma Corp.) was added to each well and culturing was performed for approximately 2 hours in a 5% CO2 incubator (37° C.). The tubes formed in the collagen gel of each well were stained by the MTT, the tube images were loaded into a computer (Macintosh), and the total length of the tubes was determined by image analysis software “MacScope” (purchased from Mitani Corp.). The ratio of the total length of the tubes formed in the well containing the test substance with respect to the total length of the tubes formed in the well containing no test substance was expressed as a percentage, and the concentration of each test substance required for 50% inhibition of tube formation (IC50) was determined from the ratio value.
This assay is used to determine inhibition of a test substance on tyrosine kinase activity. DNA coding for the cytoplasmic domain of VEGFR2 is obtained by total cDNA synthesis (Edwards M, International Biotechnology Lab 5(3), 19-25, 1987) or by cloning. Expression in an appropriate expression system can produce a polypeptide with tyrosine kinase activity. The cytoplasmic domain of VEGFR2 obtained by expression of recombinant protein in, for example, insect cells has been found to exhibit intrinsic tyrosine kinase activity. For VEGFR2 (Genbank Accession No. L04947), the 1.7 kb DNA fragment described by Terman et al. (Oncogene, 6(9), 1677-1683, 1991), coding for the cytoplasmic domain, beginning with lysine 791 and including the termination codon, was isolated from a human placental cDNA library (purchased from Clontech Laboratories, Inc.) and cloned in a Baculovirus expression vector (pFastBacHis, purchased from GIBCO BRL). The recombinant construct was transfected into insect cells (Spondoptea frugiperda9 (Sf9)) to prepare a recombinant Baculovirus. (Instructions for preparation and use of recombinant Baculovirus may be found in standard texts, such as “Bac-To-Bac Baculovirus Expression System” (GIBCO BRL).) The cytoplasmic fragment starting from lysine 398 (FGFR1, Genbank Accession No. X52833), the cytoplasmic fragment starting from lysine 558 (PDGFRβ, Genbank Accession No. M21616) or the cytoplasmic fragment starting from lysine 974 (HGFR, Genbank Accession No. J02958) may be cloned and expressed by the same method for use in assays for other tyrosine kinases. EGFR was purchased from Sigma Co. (Product No. E-2645).
For expression of the VEGFR2 tyrosine kinase, Sf9 cells were infected with the VEGFR2 recombinant virus and collected after 48 hours. The collected cells were rinsed with ice-cooled phosphate buffered saline (PBS) and then resuspended using 20 ml of ice-cooled Lysis Buffer (50 mM Tris-HCl (pH 8.5), 5 mM 2-mercaptoethanol, 100 mM KCl, 1 mM phenylmethylsulfonyl fluoride, 1% (v/v) NP-40) per 1.5×108 cells. The suspension was centrifuged at 12,000 rpm for 30 minutes at 4° C. and the supernatant was obtained.
The supernatant was added to a Ni-NTA agarose column (3 ml, purchased from Qiagen) equilibrated with Buffer A {20 mM Tris-HCl (pH 8.5), 5 mM 2-mercaptoethanol, 500 mM KCl, 20 mM imidazole, 10% (v/v) glycerol}. The column was washed with 30 ml of Buffer A, and then with 6 ml of Buffer B {20 mM Tris-HCl (pH 8.5), 5 mM 2-mercaptoethanol, 1M KCl, 10% (v/v) glycerol}, and finally with 6 ml of Buffer A. After washing, it was eluted with 6 ml of Buffer C {20 mM Tris-HCl (pH 8.5), 5 mM 2-mercaptoethanol, 100 mM KCl, 100 mM imidazole, 10% (v/v) glycerol}. The eluate was placed on a dialysis membrane (purchased from Spectrum Laboratories) and dialyzed with a dialysis buffer {20 mM Tris-HCl (pH 7.5), 10% (v/v) glycerol, 1 mM dithiothreitol, 0.1 mMNa3VO4, 0.1 mM EGTA}. After dialysis, it was supplied for SDS-electrophoresis, and the recombinant protein (His6-VEGFR2, cytoplasmic domain of VEGFR2 fused with 6 histidine residues at the N-terminus) detected at a molecular weight of approximately 100 kDa with Coumassie Brilliant Blue staining was assayed using BSA (bovine serum albumin, purchased from Sigma Co.) as the standard substance, and stored at −80° C. until use. Using the same method for the cytoplasmic domains of FGFR1, PDGFRβ and HGFR yielded respective recombinant proteins fused with 6 histidine residues at the N-termini (His6-FGFR1, His6-PDGFRβ or His6-HGFR).
The tyrosine kinase reaction was conducted as follows. In the case of VEGFR2, for example, 10 μl of a kinase reaction solution {200 mM Hepes (pH 7.4), 80 mM MgCl2, 16 mM MnCl2, 2 mM Na3VO4}, 250 ng of biotin-bound poly(Glu4:Tyr1) (biotin-poly(GT), purchased from CIS Diagnostics Co.) (6 μl of a 15-fold dilution with distilled water), 15 ng of His6-VEGFR2 (10 μl of a 240-fold dilution with 0.4% BSA solution) and the test substance dissolved in dimethylsulfoxide (4 μl of a 100-fold dilution with 0.1% BSA solution) were added into each well of a 96-well round-bottom plate (NUNC Co., Product No. 163320), to a total of 30 μl. Next, 10 μl of 4 μM ATP (diluted with distilled water) was added prior to incubation at 30° C. for 10 minutes, and then 10 μl of 500 mM EDTA (pH 8.0) was added.
The tyrosine phosphorylated biotin-poly(GT) was measured by the Homogenous Time-Resolved Fluorescence (HTRF) method (Analytical Biochemistry, 269, 94-104, 1999). Specifically, the kinase reaction solution was transferred to a 96-well black half-plate (Product No. 3694, Coster, Inc.), 7.5 ng of europium cryptate-labeled anti-phosphotyrosine antibody (Eu(K)-PY20, purchased from CIS Diagnostics Co.) (25 μl of a 250-fold dilution with 20 mM Hepes (pH 7.0), 0.5 M KF, 0.1% BSA solution) and 250 ng of XL665-labeled streptavidin (XL665-SA, purchased from CIS Diagnostics Co.) (25 μl of a 62.5-fold dilution with 20 mM Hepes (pH 7.0), 0.5 M KF and 0.1% BSA solution) were added thereto, the mixture was allowed to stand at room temperature for 30 minutes, and then the fluorescent intensity was measured at 665 nm and 620 nm under irradiation with an excitation wavelength of 337 nm using a Discovery HTRF Microplate Analyzer (Packard Co.). The tyrosine phosphorylation rate for the biotin-poly(GT) was expressed as the delta F % value as described in the HTRF Standard Experiment Methods text by CIS Diagnostics Co. The delta F % value in the presence of the test substance was determined as a ratio (%) with the delta F % value with addition of His6-VEGFR2 in the absence of the test substance defined as 100% and the delta F % value in the absence of both the test substance and His6-VEGFR2 defined as 0%. This ratio (%) was used to calculate the test substance concentration required for 50% inhibition of VEGFR2 kinase activity (IC50).
Measurement of inhibition against FGFR1, EGFR and HGFR kinase activity was conducted using 15 ng of His6-FGFR1, 23 ng of EGFR and 30 ng of His6-HGFR, respectively, according to the tyrosine kinase reaction and HTRF method described above.
Measurement of inhibition against PDGFRβ kinase activity was conducted using 50 ng of His6-PDGFRβ according to the tyrosine kinase reaction described above, followed by detection of tyrosine phosphorylated biotin-poly(GT) by the following method.
Specifically, the kinase reaction solution was added to a 96-well streptavidin-coated plate (Product No. 15129, Pierce Chemical) and incubated at room temperature for 30 minutes. After rinsing 3 times with 150 μl of a rinsing solution {20 mM Tris-HCl (pH 7.6), 137 mM NaCl, 0.05% Tween-20, 0.1% BSA}, 70 μl of anti-phosphotyrosine (PY20)-HRP conjugate (Product No. P-11625, Transduction Laboratories) {2000-fold dilution with 20 mM Tris-HCl (pH 7.6), 137 mM NaCl, 0.05% Tween-20, 1% BSA} was added thereto and incubation was performed at room temperature for 1 hour. After incubation, it was rinsed 3 times with 150 μl of the rinsing solution, and 100 μl of TMB Membrane Peroxidase Substrate (Product No. 50-5077-03, Funakoshi Co., Ltd.) was added to initiate the reaction. After stationing at room temperature for 10 minutes, 100 μl of 1 M phosphoric acid was added to suspend the reaction, and the absorbance at 450 nm was measured with a microplate reader (BIO KINETICS READER EL304, Bio-Tek Instruments). The absorbance ratio in the presence of the test substance was determined with respect to 100% as the absorbance with addition of His6-PDGFRβ and no test substance, and 0% as the absorbance without addition of the test substance or His6-PDGFRβ. This absorbance ratio was used to calculate the test substance concentration required for 50% inhibition of PDGFRβ kinase activity (IC50).
Cancer cells (for example, KP-4 human pancreatic cancer cells) or normal cells (for example, IEC-18 rat ileal epithelial cells) were subcultured in RPMI 1640 medium containing 10% FBS (purchased from Nissui Pharmaceutical Co., Ltd.) every 3-4 days, and cells in the growth phase were used. After recovering the cells using trypsin-EDTA, the cells were counted and a 0.1 ml cell suspension of each diluted with 10% FBS-containing RPMI 1640 medium (to 2×103 cells/well for KP-4 and 8×102 cells/well for IEC18) was spread onto a 96-well plate for cell culturing. Culturing was performed overnight in a 5% CO2 incubator (37° C.), and then a 0.1 ml solution of the test substance diluted with 10% FBS-containing RPMI 1640 was added and culturing was continued in a 5% CO2 incubator (37° C.). On the 3rd day after addition of the test substance, 0.05 ml of a 3.3 mg/ml MTT solution (purchased from Sigma Co.) was added, and culturing was continued in the 5% CO2 incubator (37° C.) for approximately 2 hours. After aspirating off of the culture supernatant and DMSO dissolution of the formazan produced in each well, the absorbance of each well was measured using an MTP-32 plate reader (Corona Electric) at a measuring wavelength of 540 nm and a reference wavelength of 660 nm. The absorbance ratio in the substance-added well was determined as a percentage with respect to the absorbance of the well without addition of the test substance, and this ratio was used to calculate the test substance concentration required for 50% inhibition of cell growth (IC50).
L6 (rat myloblasts) were subcultured in 10% FBS-containing D-MEM medium (purchased from Nissui Pharmaceutical Co., Ltd.) every 3-4 days, and cells in the growth phase were used. The cells were recovered using trypsin-EDTA and rinsed once with 10% FBS-free D-MEM medium, and the cells were counted. After spreading 0.1 ml of a cell suspension diluted with 10% FBS-free D-MEM medium onto a Type I collagen-coated 96-well tissue culturing plate at 5×103 cells/well, culturing was performed overnight in a 5% CO2 incubator (37° C.). On the following day, 0.05 ml of a solution of the test substance diluted with 10% FBS-free D-MEM medium was added, with almost simultaneous addition of 0.05 ml of a 40 nM PDGF solution (10 nM final concentration), and culturing was continued in the 5% CO2 incubator (37° C.). On the 3rd day after addition of the test substance, 0.01 ml of WST-1 solution (purchased from Wako Pure Chemical Industries Co., Ltd.) was added to each well, and culturing was continued in the 5% CO2 incubator (37° C.) for approximately 3 hours until coloration. The absorbance of each well was measured using an MTP-32 plate reader (Corona Electric) at a measuring wavelength of 415 nm and a reference wavelength of 660 nm. The absorbance ratio in the substance-added well was determined as a percentage with respect to the absorbance of the well without addition of the test substance, and this ratio was used to calculate the test substance concentration required for 50% inhibition of cell growth (IC50).

In the case of HUVEC, for example, EGM-2 medium (purchased from Clonetics Corp.) was used for culturing at 37° C. under 5% CO2 conditions. At a prescribed time after reaction with the test substance, the cells were lysed using TRIZOL reagent (purchased from GIBCO BRL) according to the manufacturer's protocol. Specifically, it was accomplished as follows. A 1 ml portion of TRIZOL reagent is added per 10 cm2 culturing area, and pipetting is carried out several times to collect the cells. After centrifuging the sample, the obtained supernatant is allowed to stand at room temperature for 5 minutes, and then chloroform (purchased from Junsei Chemical Co., Ltd.) is added in a proportion of 0.2 ml with respect to 1 ml of TRIZOL reagent used. The solution is vigorously shaken and stirred for 15 seconds and allowed to stand at room temperature for 2-3 minutes, and then centrifuged (12,000×g, 10 min, 4° C.). After centrifugation, the aqueous layer is transferred to a fresh tube, isopropyl alcohol (purchased from Wako Pure Chemical Industries Co., Ltd.) is added in a proportion of 0.5 ml to 1 ml of TRIZOL reagent used, and the mixture is allowed to stand at room temperature for 10 minutes and then centrifuged (12,000×g, 10 min, 4° C.). The obtained precipitate is rinsed with 75% ethanol (purchased from Wako Pure Chemical Industries Co., Ltd.) and then air-dried and supplied as total mRNA for the following procedure.
2. Quantitation of RNA
The RNA may be quantitated by techniques such as Northern blotting analysis, DNA microarray, RT-PCR, quantitative PCR and the like, with DNA microarray and quantitative PCR being preferred. Explanations of these techniques are provided below, but are not intended to be limitative on the invention.
1) Quantitation with a DNA microarray (Schena M. et al., Science, 270 (5235), 467-70, 1995 and Lockhart, D. J. et al., Nature Biotechnology, 14 (13), 1675-1680, 1996) is carried out in the following manner.
[1] cDNA Synthesis and Biotin Labeling
The initially obtained RNA was used as template to synthesize double-stranded cDNA with a SuperScript Choice System (purchased from GIBCO BRL) and T7-d(T)24 primer, and then this cDNA was used as template for synthesis of biotinylated cRNA.
Specifically, 5 μg T7-d(T)24 primer, 1×first strand buffer, 10 mM DTT, 500 μM dNTP mix and 20 unit/μl SuperScript II Reverse Transcriptase were added to 10 μg of RNA, and reaction was conducted at 42° C. for 1 hour to synthesize single-stranded cDNA. Next, 1×second strand buffer, 200 μM dNTP mix, 67 U/ml DNA ligase, 270 U/ml DNA polymerase I and 13 U/ml RNaseH were added and reaction was conducted at 16° C. for 2 hours to synthesize double-stranded cDNA. Finally, 67 U/ml T4 DNA polymerase I was added for reaction at 16° C. for 5 minutes, after which 10 μl of 0.5M EDTA (purchased from Sigma Co.) was added to suspend the reaction.
The obtained cDNA was purified with phenol/chloroform (purchased from Ambion, Inc.), and an RNA Transcript Labeling Kit (purchased from Enzo Diagnostics, Inc.) was used for labeling with biotinylated UTP and CTP according to the manufacturer's protocol. The reaction product was purified with an RNeasy column (purchased from Qiagen), and then heating was performed for 35 minutes at 94° C. in 200 mM Tris acetate (pH 8.1), 150 mM magnesium acetate and 50 mM potassium acetate, for fragmentation of the cRNA.
[2] DNA Microarray (GeneChip) Hybridization and Measurement
The fragmented cRNA is hybridized with a GeneChip (purchased from Affymetrix Corp.) Hu6800/Human Cancer G110 Array or an equivalent product, in 100 mM MES, 1M sodium salt, 20 mM EDTA, 0.01% Tween20, for example, at 45° C. for 16 hours. After hybridization, the GeneChip is rinsed and dyed according to protocol EukGE-WS2 included with the Affymetrix fluidics station or the optimum protocol for the array used. The dyeing is carried out using streptavidin-phycoerythrin (purchased from Molecular Probe) and biotinylated anti-streptavidin goat antibody (purchased from Vector Laboratories). The dyed GeneChip is scanned using an HP argon-ion laser confocal microscope (purchased from Hewlett Packard Co.), and the fluorescent intensity is measured. The fluorescence was measured with excitation at 488 nm and emission at 570 nm.
All of the quantitative data analysis was carried out using GeneChip software (purchased from Affymetrix Corp.) or Genespring (purchased from Silicon Genetics). For RNA quantitation, the average of the difference (perfect match hybridization signal—mismatch signal) is determined for each probe family, and the gene expression is judged as having significantly “increased” or “decreased” if the value is 5 or greater and the RNA quantities are disparate under 2 conditions, and preferably if they are disparate by a factor of 1.8 or greater.
2) Quantitation by quantitative PCR is conducted in the following manner.
Quantitative PCR is accomplished in the following manner using SYBR Green (purchased from Applied Biosystems) and an ABI Prism 7700 Sequence Detection System (purchased from Perkin-Elmer Applied Biosystems) or an equivalent apparatus.
The procedure is carried out by the two stages of reverse transcription and PCR reaction. In the reverse transcription of the first stage, dNTP, oligo d(T)16 primer, RNase Inhibitor and Multiscribe Reverse Transcriptase (purchased from Perkin-Elmer Applied Biosystems) are added to the obtained RNA, the temperature is kept at 25° C. for 10 minutes, and then heating is effected at 48° C. for 30 minutes. The reaction is suspended by heating at 95° C. for 5 minutes.
The obtained cDNA is then supplied to the PCR reaction of the second stage. The PCR reaction is carried out in a reaction system comprising, for example, 4 ng cDNA, 1×SYBR PCR buffer, 3 mM MgCl2, 200 μM each dATP, dCTP and dGTP, 400 μM dUTP, 200 nM primer pair, 0.01 U/μl AmpErase UNG and 0.025 U/μl Ampli Taq Gold DNA Polymerase (purchased from Perkin-Elmer Applied Biosystems). The reaction was conducted under conditions with 50° C. for 2 minutes and 95° C. for 10 minutes followed by 40 cycles of 95° C. for 20 seconds, 55° C. for 20 seconds and 72° C. for 30 seconds. The primers and probes are designed using Primer Expression (purchased from Perkin-Elmer Applied Biosystems) or equivalent software. The different test substances are compared while compensating the quantitative values based on the mRNA level of a housekeeping gene having low transcription level fluctuation, preferably GAPDH, in each specimen.
[1] Construction of VEGF (Vascular Endothelial Growth Factor) Expression Vector
PCR was conducted using a human placenta cDNA library (purchased from Toyobo Co., Ltd.) as the template and the VEGF sequences 5′CCGGATCCATGAACTTTCTGCTG3′ (SEQ ID NO: 1) and 5′ GTGAATTCTGTATCGATCGTT3′ (SEQ ID NO: 2) as primers. After completion of the PCR reaction, the 5′ ends were phosphorylated and an approximately 600 bp DNA band was separated by 1.2% agarose gel electrophoresis. After polymerization by self-ligation, the cDNA was cut with EcoRI and BamHI and inserted into the EcoRI and BamHI sites of vector pUC19. This was used to transform E. coli JM83, and plasmids were recovered from the transformed clones. A VEGF cDNA fragment was cut out of the plasmids with HindIII and EcoRI and then inserted into an expression vector containing the neomycin resistance gene.
[2] Preparation of VEGF High-Expressing Strain
After overnight culturing of KP-1 human pancreatic cancer cells (3×106 cells) with 10% FCS-containing RPMI 1640 medium, an Effectene Transfection Reagent Kit (purchased from Qiagen) was used for introduction of 3 μg of VEGF expression vector into the KP-1 cells. After culturing in 10% FCS-containing RPMI 1640 medium also containing 600 μg/ml of Geneticin, the high-expressing drug-resistant cells were selected as VEGF high-expressing KP-1 cells (KP-1/VEGF).
[3] Measurement of VEGF Level in Culture Supernatant
The KP-1/VEGF cells were prepared to 5×105 cells/ml, and 0.5 ml thereof was dispensed into each well of a 24-well plate and cultured at 37° C. for 24 hours. The culture supernatants were collected and the VEGF levels thereof measured using a VEGF measuring kit (purchased from IBL Co., Ltd.) for confirmation of high expression.
[4] Evaluation of In Vivo Angiogenesis-Inducing Activity using Mouse Dorsal Air Sac Model
Millipore rings (purchased from Nihon Millipore) were sealed with 0.45 μm Durapore™ filter membranes (purchased from Nihon Millipore) to create chambers. KP-1/VEGF human pancreatic cancer cells (3×106) suspended in 0.17 ml of collagen gel were injected into each chamber through the injection port, and the chambers were sealed. Approximately 10 ml of air was then injected in the dorsal skin of 6-week-old C57BL/6N female mice under anesthesia to produce pouches, and the prepared chambers were transplanted therein. About 6 hours after completing transplantation, a test substance suspended in 0.5% methyl cellulose was orally administered (0.1 ml/10 g body weight), and this was continued once a day for the next 4 days.
On the 4th day after transplanting the chambers, 0.2 ml of 51Cr (Amersham Pharmacia)—labeled mouse erythrocytes (2.5×106 cpm/ml) were injected through the caudal veins of each of the mice with the transplanted chambers. After a prescribed period, the skin in contact with the chamber was excised and frozen, the section in direct contact with the chamber was precisely cut off, and the radioactivity was measured with a γ-counter. The blood volume was calculated from the radioactivity and used as an index of the in vivo angiogenesis-inducing activity. The angiogenesis volume was recorded as this measured blood volume minus the blood volume obtained with transplantation of a chamber containing only collagen gel. The experiment was conducted using 10 mice in the control (solvent-administered) group and 5 mice in each compound-administered group.
VEGF high-expressing pancreatic cancer cells (KP-1/VEGF) suspended in PBS at a concentration of 1×107 cells/ml were transplanted under the right flank skin of 6-week-old female Balb/c (nu/nu) mice in a volume of 0.1 ml. When the tumor volume reached approximately 100 mm3, the test substance was orally administered over a period of 2 weeks with a schedule of 5 days per week. The test substance was suspended in 0.5% methyl cellulose for an administered volume of 0.1 ml/10 g body weight. The tumor size was measured twice a week using a micrometer caliper. The tumor volume was determined by measuring the long and short diameters of the tumor with a micrometer caliper, and calculating 1/2×(long diameter×short diameter×short diameter). The experiment was conducted using 10 mice in the control (solvent-administered) group and 5 mice in each test substance-administered group.
After abdominal section of 6- to 7-week-old female Balb/c (nu/nu) mice under anesthesia and exposure of the pancreases, VEGF high-expressing pancreatic cancer cells (KP-1/VEGF) suspended in PBS at a concentration of 1×107 cells/ml were directly transplanted into each pancreas head at a volume of 0.1 ml. Upon the 4th week after transplantation, the test substance was orally administered over a period of 10 weeks with a schedule of 5 days per week. The test substance was suspended in 0.5% methyl cellulose for an administered volume of 0.1 ml/10 g body weight. Body weight was periodically measured twice per week during the test period, and the presence of ascites accumulation was recorded based on appearance. The survival period was based on tabulating the number of mice which died up until completion of the experiment. Tumor weight was measured in individuals suitable for postmortem autopsy. The experiment was conducted using 8 to 10 mice per group.
According to the present invention, it is possible to provide novel compounds that exhibit (1) powerful inhibiting action against invasive tube formation by vascular endothelial cells induced by an angiogenic factor mixture comprising Epidermal Growth Factor (EGF)/VEGF/Fibroblast Growth Factor 2 (FGF2)/Hepatocyte Growth Factor (HGF)/Tumor Necrosis Factor alpha (TNF-α), (2) powerful inhibiting action against tube formation by vascular endothelial cells specifically induced by single angiogenic factors (for example, VEGF, FGF, HGF and other such factors), and 3) powerful inhibiting action against receptor kinases for various angiogenic factors. It is further possible to provide novel compounds which are highly useful as medicines.
Among the group of compounds with the action of (1) to (3) described above there may also be provided a group of compounds with tumor cell growth-inhibiting action.
Incidentally, angiogenesis in the body is known to depend not on a single angiogenic factor but rather on the additive and synergistic effect of multiple angiogenic factors ((1) Koolwijk P, van Erck M G M, de Vree W J A, Vermeer M A, Weich H A, Hane maaijer R, van Hinsbergh V W M. Cooperative effect of TNF-alpha, bFGF and VEGF on the formation of tubular structures of human microvascular endothelial cells in a fibrin matrix. Role of urokinase activity. J. Cell Biol. 1996, 132, P1177-1188.; (2) Tallquist M D, Soriano P, Klinghoffer R A. Growth factor signaling pathways in vascular development. Oncogene 1999, 18, P7917-7932.).
Thus, the compounds of the invention which inhibit tube formation induced by multiple angiogenic factors produced by cancer cells and the like are expected to exhibit powerful angiogenesis inhibition in vivo, and should be highly useful as angiogenesis inhibitors. Moreover, the compounds of the invention may be useful as prophylactic or therapeutic agents for diseases for which angiogenesis inhibition is effective, and specifically as angiogenesis inhibitors, antitumor agents, angioma treatment agents, cancer metastasis inhibitors, retinal neovascularization treatment agents, diabetic retinopathy treatment agents, general inflammatory disease treatment agents, inflammatory disease treatment agents for deformant arthritis, rheumatoid arthritis, psoriasis, delayed hypersensitivity reaction and the like, or atherosclerosis treatment agents, and particularly as antitumor agents, based on their angiogenesis inhibition.
