SULFAMIDE DERIVATIVES AND PHARMACEUTICAL COMPOSITION FOR UPREGULATION OF LIPID METABOLISM COMPRISING SAME

Field of the Invention

The present invention relates to a novel sulfamide derivative, a pharmaceutically acceptable salt thereof, and a pharmaceutical composition for upregulating the lipid metabolism comprising same as an active ingredient.

Background of the Invention

Essential lipids such as cholesterols and fatty acids required by organs in the body are transported in the form of lipoproteins e.g., triglycerides (TGs), cholesterol esters, phospholipids and apolipoproteins. VLDLs (very low density lipoproteins) containing TGs are secreted from the liver and play the role of transporting fatty acids to each organ. The VLDLs transported to adipocyte is used for energy storage, and those transported to cardiac or skeletal muscles are used for energy production. VLDL releases a fatty acid, and it is converted to a LDL (low density lipoprotein) by the action of a lipoprotein lipase produced in adipocyte, skeletal muscle or macrophage, and the resulting LDL is transported to surrounding tissues to be used for steroidogenesis or maintaining cell membranes. Excess cholesterols present in many cells, on the other hand, are transported to the liver in the form of HDL (high density lipoprotein), and metabolized to nontoxic bile acids. Thus, if the above energy homeostasis process breaks down, insulin resistance syndrome or metabolic syndrome (X-syndrome) appears as the result of lipids accumulating in the body, triggering obesity, diabetes, heart diseases, inflammation, insulin resistance, dislipidemia and hypertension (Lee et ah, Endocrinology, 144, 2201-2207, 2003). The human body contains PPARs (peroxisome proliferating-activated receptors) which function as a hormone system in charge of physiological control of lipids contained in food. PPARs belonging to the family of nuclear receptors, and consist of 2nd zinc finger binding domain and hydrophobic ligand binding pocket, and they are divided into three subtypes, "PPAR α ", "PPAR Y " and "PPAR δ " (Willson et al, Journal of Med. Chem., 43, 527-550, 2000). PPAR α is expressed in the muscle, heart, kidney, and particularly in a high level in the liver which controls the disintegration of fatty acids. PPAR y is expressed in adipocyte and macrophage, and contrails the proliferation of adipocyte, lipid storage and glucose homeostasis, besides checking the proliferation of keratinocyte. A study using PPAR α null mice revealed that PPAR α is involved in the beta oxidation of a long chain fatty acid such as palmitic acid present in mitochondria (Costet et al, J. Bio. Chem., 273, 5678-5684, 1998). For example, the importance of PPAR α in the lipid homeostasis has been recognized by a study which measured the accumulation of lipids in the liver and heart of PPAR α null mice, which showed hypercholesterolemia and obesity as a result of accumulated excess triglycerides (Costet et ah, J. Bio. Chem., 273, 29577-29585, 1998). It is also known that PPAR α is a target protein of OEA (oleylethanolamide) which controls the appetite and body weight of null mice (Fu et al, Nature, 425 (6953), 90-93, 2000). In addition, the activation of PPAR α causes lowering of the expression of apolipoprotein C-III which is known to inhibit the hydrolysis of TGs by LDL, leading to the inhibition of the expression of VCAM (vascular cell adhesion molecule)- 1 to prevent arteriosclerosis (Marx et al, Circulation, 99, 3125-3131, 1999), IL-linterleukin-1 (interleukin-l)-induced secretion of IL-6 (interleukin- 6), or the production of prostaglandin in vascular smooth muscles (Staels et al., Nature, 393, 790-793,1998). The tertiary structure of PPAR α has been reported to take the form of a complex with agonist GW409544 (Xu et al, PNAS, 98, 13919-13924, 2001), and also reported was the finding that the difference between Tyr (314 amino acid) of PPAR α and His (323 amino acid) of PPAR y determines the selectivity of PPAR. In addition, the fatty acid binding pockets of PPAR α and PPAR Y are much more pronounced than those of PPAR δ (Nolte et al, Nature, 395, 137-143, 1998). Thus, the tertiary structure of PPAR α is considered to the key in the development of PPAR α agonists. Compounds which have been previously found to affect the activity of PPAR α are Wy- 14643, clofibrate, fenofibrate, bezafibrate, GW2331, SW9578 and BM17.0744 (Willson et al, J. Med. Chem., 43, 527-550, 2000). These agonists of PPAR α bring about increased insulin sensitivity in mouse models by way of reducing TGs, adiposity and steatosis of the liver or muscle (Chou et al, JBC, 277, 24484-24489, 2002; Kim et al, Diabetes, 52, 1770-1778, 2003; and Peters et al, MoI. Cell. Biol, 20, 5119-5128, 2000). Fenofibrate or gemfibrozil reduces TGs in blood and elevates the HDL level in hyperlipidemia patients (Lee et al, Endocrinology, 144, 2201-2207, 2003), but such an agonist requires a large daily dosage (300 to 1,200 mg/day), and therefore, there exists a need to develop more effective PPAR α agonists having excellent selectivity against PPAR α .

Test Example 1: PPAR α agonist assay

Step 1) Exogeneous PPAR α agonist assay

Cross-activation assay of the compounds of Examples 1 to 134 against human PPAR α was carried out using a DNA construct of PPAR α including its ligand binding domain and GAL4 DNA binding domain (Sher et al, Biochemistry 32, 5598-5604, 1993) to analyze whether any of the compounds binds to the ligand binding domain of PPAR α expressed by the construct to affect the PPAR α activity. When the GAL4 DNA binding domainm which is fused with PPAR α ligand binding domain, binds to UAS (upstream activation sequence) of firefly-luciferase, the luciferase is expressed. Therefore, the effect of each of the compounds of Examples on PPAR α activation can be evaluated by analyzing the activation of luciferase. Specifically, 2 X 104 of HepG2 (ATCC HB-8065) or 293T cells (ATCC CRL-1573) were aliquotted into each well of a 96-well plate and cultured for overnight at 37 °C in a CO2 incubator (culture condition: DMEM, 10% FBS and 1% antibiotics). The transformation of PPAR α DNA was traced as follows. First, a mixture of the following ingredients in amounts per well; Solution A (Promega) containing 50 ng of full length human PPAR α DNA, 50 ng of firefly- luciferase construct, 5 ng of Renilla-luciferase construct, 1.0 μJl of PLUS™ reagent, and 8.3 μi of a serum-free medium containing no antibiotics; was prepared and kept at room temperature for 15 min. Solution B, which contained 0.5 μi of Lipofectamine™ reagent and 9.5 μi of serum-free medium without antibiotics per well, and Solution C, which contained 50 μi of serum-free medium per well), were prepared. Solutions A, B and C were mixed together to prepare lipofectamin-DNA complex, and the mixture was kept at room temperature for 15 min. Single layer of cells on each well of a 96-well plate were washed with serum-free DMEM, 70 μH of lipofectamine- DNA complex prepared above was added thereto, the plate was incubated at 37 °C in a 5% CO2 incubator for 3 hours to transform the cells, and 50 μ M of a diluted solution of each of the compounds of Examples 1 to 134 per well was added to each well to a final concentration 25 μ M, and incubated at 37 °C in a CO2 incubator for 48 hours. Then, the medium was removed, 50 βi of passive lysis buffer (Promega) was added thereto, and the plate was shook at room temperature for 20 min to lysis cells. 40 μi of Lucif erase Assay reagent of Dual Luciferase Kit (Invitrogen) per 20 μJl of cell lysis buffer was added to the plate, followed by reacting at 20 °C for 8 seconds, and 40 μJl of Stop & GIo reagent (Promega) as a stop solution was added thereto to quench the reaction. The luminescence intensities of F-luciferase and R-luciferase were measured with MicroLumat Plus (Berthord Technology). The result was analyzed in terms of activity increase when 25 μ M of one of the compounds of Examples was treated, relative to the control; and EC50, the concentration at which the activity of the test compound increased by 50% over that of control (Tables Ia to Ic, wherein ND means not treating the inventive compound).

Step 2) Endogeneous PPAR α agonist assay

The procedure of Step 1 was repeated except for using a firefly- luciferase DNA construct containing Renilla-lucif erase construct, full length human PPAR α , RXR (retinoid X receptor) and PPRE (peroxisome proliferator-responsive element) (Sher et al., Biochemistry 32, 5598-5604, 1993; and Fleischhauer et al., Hum Genet 90, 505-510, 1993) to transform 293T cells, to conduct endogenous PPAR α agonist assay. Each of the compounds of Examples was used in such a treatment which lasted for 48 hours, and the luciferase activity of the resulting heterodimer, a R/R (endogenous binding partner of PPAR) bound to a full length PPAR α with the compounds, was measured in accordance with the same method of Step 1. The measured values are showed in Tables Ia to Ic, wherein ND means not treated with any of the inventive compound. As shown in Tables Ia to Ic, the inventive compounds have a useful effect on significant increase of PPAR, a lipid metabolism related enzyme. Table Ia

Test Example 2; Anti-obesity test

In order to evaluate the anti-obesity activity of the inventive compound, B6.V-Lepob/J mice (laboratory animal team of Korea Research Institute of Chemical Technology) were used for tests and lean mice as a control. Ob/ob mice are model animals for insulin-independent diabetes, suitable for studying the effect of an anti-obesity drug. 42 mice weighing 38.6+ 1.4 g were selected randomly from a pool of ob/ob mice (7-9 weeks old), and divided into groups of 7 mice each. The test was carried out at a constant temperature (24+0.5 "C) and humidity (55+5%) using ventilation system (10-12 times/hour), under a specific pathogen free (SPF) condition created in an automatic on-off cycle of 12 hours. The groups were divided to a control group treated only with an excipient, a positive control group treated with fenofibrate, and test groups treated with each of the compounds of Examples 5, 62 and 65, at dosage 100 mg/10 ml/kg body weight. Each of the test and control compounds was diluted with 0.5% CMC to a concentration to match the above dosage, and administered orally using a syringe into the stomach twice a day (9:00 and 18:00) for a period of 4 weeks, and the following characteristics were measured.

1) General symptoms and observation of dead animal

The conditions, behavioral changes, addictive symptoms and the death rate were observed constantly during the test period. As shown in Figs. Ia and Ib, the daily feed intakes of the test groups treated with the compounds of Examples 5, 62 and 65 were significantly reduced for the first week of the test as compared to the control group (P<0.005 significance level, Fig. Ia), and the cumulative amounts of total feed intake showed a similar result (P<0.05 significance level, Fig. Ib).

Therefore, the compound of the present invention exerts a positive effect on reducing feed intake. 2) Body weight measurement

The average body weight of each group was measured every 3 days after the administration, and the changes in the average body weight and body weight gain (measured body weight - initial body weight) were analyzed. As shown in Figs. 2a (the change in the average body weight) and 2b (the change in the body weight gain), the body weight of each of the test groups was significantly reduced as compared to that of the control group. Particularly, the change in the average body weight of the test group treated with the compound of Example 62 was markedly reduced at day 10 from the administration as compared to the control group (P<0.01, P<0.005 significance level, Fig. 2), and the change in the body weight gain of the compound was evidently lower at day 7 from the administration as compared to the control group (P<0.01 significance level, Fig. 2). The test group treated with the compound of Example 62 showed an improved effect as compared to the positive control group treated with fenofibrate, the compounds of Examples 5 and 65 showing similar results.

3) Measurement of lipid metabolism-related materials and insulin concentration in blood

28 days after the administration, experimental mice were fasted for 16 hours, and the concentrations of lipid metabolism-related materials such as triglyceride, free fatty acid and cholesterol, and insulin in blood were measured. Specifically, a blood sample was collected from the ocular venous plexus of each mouse and centrifuged to separate plasma. The glucose (GLU), HDL- cholesterol (HDL), LDL-cholesterol (LDL), triglyceride (TG) and free fatty acid (NEFA) levels were measured by enzymatic assay using 2 kinds of Selectra (Vital Lab), an automatic biochemical analyzer, and the insulin concentration was measured by ELISA using an insulin detection kit (Shibayagi). The result is showed in Table 2.

Table 2

As shown in Table2, the free fatty acid concentration was similar among the groups, and the triglyceride concentration was significantly lower for the group treated with the compound of Example 62 as compared to a control (P<0.05 significance level). The LDL concentration of the group treated with the compound of Example 5 (P<0.05 significance level)was low. The HDL concentration was high for groups treated with the compounds of Example 62 and 65, respectively, and the GLU concentrations of the groups treated with the compounds of Example 5, 62 and 65, respectively, were much lower than that of the control or positive control group.

4) Oral glucose tolerance test (OGTT)

28 days after the administration, each of the experimental mice was fasted for 16 hours, 2 g/kg of glucose was administered thereto, a blood sample was collected from the ocular venous plexus thereof at 0, 15, 30, 60 and 120 min from the administration, and the glucose concentration and AUC (area under the curve, Skrumsager et al., J Clin Pharmacol. 43, 1244-1256, 2003) were determined. As shown in Figs. 3a to 3c, the glucose concentration during the fast was observed to the significantly low for the test groups treated with the compounds of Examples 5, 62 and 65, respectively, as compared to the control group (P<0.05 significance level, Fig. 3c). The glucose concentration became significantly low at 30 and 60 min after the glucose administration for the test groups treated with the compounds of Examples 62 and 65, respectively, as compared to the control group (P<0.01, P<0.05 significance level, Fig. 3a), and the total changes in the glucose concentration represented by AUC were much lower for the test groups treated with the compounds of Examples 5, 62 and 65, respectively, than that of the control group (P<0.05, P<0.005 and P<0.01 significance level, Fig. 3b). Thus, the inventive compounds can confer glucose tolerance to an animal.

5) Dissection After completing all tests, each of the mice in test treated with the compounds of Examples 5 and 62 and the positive control group treated with fenofibrate was sacrificed, the whole blood, liver, muscle and white adipose tissue thereof were extracted. White adipose tissued was divided into visceral fat and subcutaneous fat, and the amounts of the total fats and liver tissue were weighed separately. As shown in Figs. 4a to 4d, the total fat weight observed for each of the test groups treated with the compounds of Examples 5 and 62 was low (P<0.01, P<0.005 significance level, Fig. 4a). The adiposity index (fat weight/(body weight - fat weight)) (Fig. 4b), and the weights of visceral fat and subcutaneous fat (Fig. 4d) were each reduced.

While the invention has been described with respect to the above specific embodiments, it should be recognized that various modifications and changes may be made and also fall within the scope of the invention as defined by the claims that follow.
