Description

DESCRIPTION NOVEL PHENYLPYRIDINE DERIVATIVE AND DRUG CONTAINING SAME TECHNICAL FIELD The present invention relates to novel phenylpyridine derivatives that have both angiotensin II antagonistic activity and a PPAR g activation effect, and a pharmaceutical agent containing the same.
BACKGROUND ART In recent years, diseases such as diabetes, hypertension, dyslipidemia and obesity which can be a risk factor for arteriosclerotic diseases have been rapidly increasing due to changes in life style with improvements in living standard, i.e., high calorie and high cholesterol type diet, obesity, lack of exercise, aging, and the like. It is known that, although being a risk factor independent of each other, overlap of the diseases can cause an occurrence of arteriosclerotic diseases at higher frequency or aggravation of the diseases. As such, with the understanding of a condition having a plurality of risk factors for arteriosclerotic diseases as metabolic syndrome, efforts have been made to elucidate the cause of the syndrome and to develop a therapeutic method therefor.
Angiotensin II (herein below, also abbreviated as “AII”) is a peptide that is found to be an intrinsic pressor substance produced by renin-angiotensin system (i.e., RA system). It is believed that pharmacological inhibition of angiotensin II activity can lead to treatment or prevention of circulatory diseases such as hypertension. Accordingly, an inhibitor for angiotensin converting enzyme (ACE) which inhibits the enzyme for promoting the conversion of angiotensin I (AI) to angiotensin II has been clinically used as an inhibitory agent for RA system. Furthermore, an orally administrable AII receptor blocker (Angiotensin Receptor Blocker: ARB) has been developed, and losartan, candesartan, telmisartan, valsartan, olmesartan, irbesartan, and the like are already clinically used as a hypotensive agent. It is reported by many clinical or basic studies that, as having not only a hypotensive activity but also other various activities including an anti-inflammatory activity, an endothelial function improving activity, a cardiovascular remodeling inhibiting activity, an oxidation stress inhibiting activity, a proliferation factor inhibiting activity, insulin resistance improving activity, and the like, ARB is useful for cardiovascular diseases, renal diseases, arteriosclerosis, and the like (Non-Patent Documents 1 and 2). Most recently, it is also reported that ARB particularly has a kidney protecting activity which does not depend on a hypotensive activity (Non-Patent Document 3).
Meanwhile, three isoforms, i.e., a, g and d have been identified so far for peroxisome proliferator-activated receptors (PPARs) which belong to a nuclear receptor superfamily. Among them, PPARg is an isoform most abundantly expressed in an adipose tissue and it plays an important role in differentiation of adipocytes or metabolism of glycolipids.
Currently, thiazolidinedione derivatives (i.e., TZD) such as pioglitazone or rosiglitazone are clinically used as a therapeutic agent for diabetes having a PPARg activation effect, and they are known to have an activity of improving insulin resistance, glucose tolerance, lipid metabolism, and the like.
Further, it is recently reported that, based on activation of PPARg, TZD exhibits various activities including a hypotensive activity, an anti-inflammatory activity, an endothelial function improving activity, a proliferation factor inhibiting activity, an activity of interfering RA system, and the like.
It is also reported that, according to such multiple activities, TZD shows a kidney protecting activity particularly in diabetic nephropathy without depending on blood sugar control (Non-Patent Documents 4, 5, 6, 7, and 8). Meanwhile, there is also a concern regarding adverse effects of TZD caused by PPARg activation, such as body fluid accumulation, body weight gain, peripheral edema, and pulmonary edema (Non-Patent Documents 9 and 10).
It has been recently reported that telmisartan has a PPARg activation effect (Non-Patent Document 11). It has been also reported that the irbesartan has the same activity (Non-Patent Document 12). These compounds have both an RA system inhibiting activity and a PPARg activation effect, and thus are expected to be used as an integrated agent for prevention and/or treatment of circulatory diseases (e.g., hypertension, heart disease, angina pectoris, cerebral vascular disorder, cerebral circulatory disorder, ischemic peripheral circulatory disorder, kidney disease, and the like) or diabetes-related diseases (e.g., type 2 diabetes mellitus, diabetic complication, insulin resistant syndrome, metabolic syndrome, hyperinsulinemia, and the like) without increasing a risk of body fluid accumulation, body weight gain, peripheral edema, pulmonary edema, or congestive heart failure that are concerned over the use of TZD (Patent Document 1). Among them, for diabetic nephropathy, a synergistic prophylactic and/or therapeutic effect is expected from composite kidney protecting activity that is based on activities of RA system inhibition and PPARg activation.
As a compound having the activities above, pyrimidine and triazine derivatives (Patent Document 1), imidazopyridine derivatives (Patent Document 2), indole derivatives (Patent Document 3), imidazole derivatives (Patent Document 4), and condensed ring derivatives (Patent Document 5) have been reported. However, there is no description or suggestion regarding the phenylpyridine derivatives of the present invention.
Meanwhile, Patent Document 6 discloses a compound represented by the following formula (A): [Chemical Formula 1] [in the formula, R is an optionally substituted hydrocarbon residue which is optionally bonded through a hetero atom, R is an optionally substituted 5 to 7 membered heterocyclic residue having, as a group capable of constituting the ring, a carbonyl group, a thiocarbonyl group, an optionally oxidized sulfur atom or a group convertible into them, X is a direct bond or bonding via a spacer having an atomic length of two or less between the ring Y and the ring W, W and Y are an optionally substituted aromatic hydrocarbon residue optionally containing a hetero atom or an optionally substituted heterocyclic residue; n is an integer of 1 or 2, a and b forming the heterocyclic residue are independently one or two optionally substituted carbon or hetero atoms, c is an optionally substituted carbon or hetero atom, and, in the group of the formula, [Chemical Formula 2] substituent groups on adjacent two atoms forming the ring are optionally bonded to each other to form a 5 to 6 membered ring together with the two atoms forming the ring]. As a preferred W-Y ring system, biphenyl is exemplified. In the Examples, only the biphenyl derivatives are specifically described. The compounds disclosed in Patent Document 6 are different from the compounds of the present invention in terms of the ring bonded to the pyridinyl methyl group. In addition, Patent Document 6 includes no descriptions or suggestions relating to a PPARg activation effect as a pharmacological activity or treatment of diabetes, obesity, or metabolic syndromes.

Specifically, the specimen of thoracic aorta ring of a rabbit (New Zealand White: male, 2.4 to 3.0 kg) was suspended in a magnus bath filled with Krebs-Henseleite buffer (composition: 118 mM NaCl, 4.7 mM KCl, 2.55 mM CaCl , 1.18 mM MgSO , 1.18 mM KH PO , 24.88 mM NaHCO , and 11.1 mM D-glucose), 4 2 4 3 and angiotensin II (10 nM)-induced contraction was obtained in the presence of each test compound (1 n mol/L to 10 mmol/L).
During the measurement, the inside temperature of the magnus bath was maintained at 37C and the bath was continuously ventilated with a sufficient amount of mixed gas (95% O and % CO ). The angiotensin II-induced contraction was converted into a relative value (%) that is based on the angiotensin II (0.1 mM)-induced contraction in the absence of the test compound.
As a result, it was confirmed that the compounds described in the Examples have an angiotensin II antagonistic activity at the concentration of 0.1 mM. The inhibitory rate of angiotensin II (10 nM) at the test compound concentration of 0.1 mM is shown in the Table 1. As shown in the Table 1, it was confirmed that the compounds of the invention have a potent angiotensin II antagonistic activity, which is the same as telmisartan. Meanwhile, under the same condition, rate of inhibiting the angiotensin II activity by telmisartan was 85.3%.
[Table 1] Test example 2: PPARg activation effect The agonistic activity of the compounds of the invention on PPARg was measured based on the transfection assay using COS7 cells (DS Pharma Biomedical Co., Ltd., Osaka, Japan), which are the cell line derived from the kidney of the African green monkey.
COS7 cells were cultured under 5% CO concentration, and DMEM medium containing 10% fetal bovine serum, glutamic acid, and antibiotics was used as a medium.
As an expression vector, a chimera in which DNA binding domain of Gal4, which is a yeast transcription factor, and ligand binding domain of human PPARg2 are fused, i.e., a fused product between the amino acids 1 to 147 of Gal4 transcription factor and the amino acids 182 to 505 of human PPARg2, was used.
Furthermore, as a reporter vector, a firefly luciferase containing five copies of Gal4 recognition sequence in the promoter region was used. Plasmid transfection to the cells was performed according to a method which uses jetPEI (trade name, manufactured by Funakoshi Co., Ltd., Tokyo, Japan).
Furthermore, b-galactosidase expression vector was employed as an internal standard.
After the transfection into the cells, the medium was replaced with a DMEM medium (containing 1% serum) added with the test compound, and the cells were further cultured for 16 hours. After that, the luciferase activity and b-galactosidase activity in the cell lysis solution were measured.
Meanwhile, for the present test, dimethylsulfoxide (DMSO) was used for dissolution and dilution of the test compounds, and during the cell treatment, the DMSO concentration in DMEM medium (containing 1% serum) was adjusted to 0.1%. As a positive compound, rosiglitazone (trade name, manufactured by ALEXIS Corporation, Switzerland) was used.
The percentage (%) of the luciferase activity of the each test compound (1 to 30 mmol/L) was calculated when the luciferase activity of rosiglitazone (3 to 10 mmol/L) is 100% and the luciferase activity in the absence of the test compound is 0%.
The 50% effective concentration of the test compound (EC , 50% effect concentration) was calculated by using SAS Preclinical Package Ver 5.0 (trade name, manufactured by SAS institute Japan Co., Tokyo, Japan), which is a statistical analysis program.
As a result, it was confirmed that the compounds described in the Examples have a PPARg activation effect at the concentration of 30 mM. The EC results are given in the Table 2. As shown in the Table 2, it was confirmed that the compounds of the invention have a potent PPARg activation effect. In particular, several compounds in the Table 2 exhibited EC value of less than 1 mM, indicating stronger PPARg activation effect than telmisartan. Maximum activity strength of several compounds relative to the maximum activity of rosiglitazone is given in the Table 3. As shown in Table 3, it was confirmed that the compounds of the invention have an activity that is to 69% of the maximum activity of rosiglitazone and they have a sufficient agonist activity on PPARg. In particular, the maximum activity of the compounds of the Examples 40, 41, 42, and 43 was 42 to 69%, which is the same or greater than that of telmisartan. Under the same condition, the PPARg activation effect of telmisartan, i.e., EC , was 1 to 5 mM, and the maximum activity strength of telmisartan relative to the maximum activity of rosiglitazone (i.e., % MAX vs. rosiglitazone) was to 50%.
[Table 2] [Table 3] From the results obtained above, it was confirmed that the compounds of the present invention have both a potent angiotensin II receptor antagonistic activity and a PPARg activation effect. Thus, it was found that the compounds of the present invention and pharmaceutically acceptable salts thereof are useful as an effective component of a prophylactic and/or therapeutic agent for disorders involved with angiotensin II and PPARg, for example, hypertension, heart diseases, angina pectoris, cerebral vascular disorders, cerebral circulatory disorders, ischemic peripheral circulatory disorders, renal diseases, arteriosclerosis, inflammatory diseases, type 2 diabetes, diabetic complications, insulin resistance syndrome, syndrome X, metabolic syndrome, and hyperinsulinemia.
