Definitions

  • the present invention relates to a novel peptide showing excellent activities on a glucagon like peptide-1 receptor and a glucagon receptor greater than native oxyntomodulin, and a composition for the prevention or treatment of obesity comprising the peptide as an active ingredient.
  • Obesity is a severe condition that causes various diseases worldwide. It is thought to be overcome by individual efforts, and it is also believed that obese patients lack self-control. However, it is difficult to treat obesity, because obesity is a complex disorder involving appetite regulation and energy metabolism. For the treatment of obesity, abnormal actions associated with appetite regulation and energy metabolism should be treated together with efforts of obese patients. Many attempts have been made to develop drugs capable of treating the abnormal actions. As the result of these efforts, drugs such as Rimonabant (Sanofi-Aventis), Sibutramin (Abbott), Contrave (Takeda), and Orlistat (Roche) have been developed, but they have the disadvantages of serious adverse effects or very weak anti-obesity effects.
  • glucagon derivatives have received much attention.
  • Glucagon is produced by the pancreas when the level of glucose in the blood drops resulting from other medications or diseases, hormone or enzyme deficiencies.
  • Glucagon stimulates glycogen breakdown in the liver, and facilitates glucose release to raise blood glucose levels to a normal range.
  • glucagon suppresses appetite and activates hormone-sensitive lipase(HSL) of adipocytes to facilitate lipolysis, thereby showing anti-obesity effects.
  • HSL hormone-sensitive lipase
  • GLP-1 glucagon like peptide-1
  • Exendin-4 is isolated from lizard venom that shares approximately 50% amino acid homology with GLP-1 and is also reported to activate the GLP-1 receptor, thereby ameliorating hyperglycemia in patients with diabetes.
  • anti-obesity drugs including GLP-1 are reported to show side-effects such as vomiting and nausea.
  • Oxyntomodulin a peptide derived from a glucagon precursor, pre-glucagon that binds to the receptors of two peptides, GLP-1 and glucagon.
  • Oxyntomodulin represents a potent anti-obesity therapy, because it inhibits food intake like GLP-1, promotes satiety, and has a lipolytic activity like glucagon.
  • Korean Patent No. 925017 discloses a pharmaceutical composition including oxyntomodulin as an active ingredient for the treatment of overweight human, which is administered via an oral, parenteral, mucosal, rectal, subcutaneous, or transdermal route.
  • this anti-obesity drug including oxyntomodulin has a short in vivo half-life and weak therapeutic efficacy, even though administered at a high dose three times a day.
  • many efforts have been made to improve the in vivo half-life or therapeutic effect of oxyntomodulin on obesity by its modification.
  • a dual agonist oxyntomodulin is prepared by substituting L-serine with D-serine at position 2 of oxyntomodulin to increase a resistance to dipeptidyl peptidase-IV (DPP-IV) and by attaching a cholesterol moiety at the C-terminal to increase the blood half-life at the same time.
  • DPP-IV dipeptidyl peptidase-IV
  • ZP2929 (Zealand) is prepared by substituting L-serine with D-serine at position 2 to enhance resistance to DPP-IV, substituting arginine with alanine at position 17 to enhance resistance to protease, substituting methionine with lysine at position 27 to enhance oxidative stability, and substituting glutamine with aspartic acid and alanine at positions 20 and 24 and asparagine with serine at position 28 to enhance deamidation stability.
  • oxyntomodulin (Merck) was enhanced to show half-life 8 ⁇ 12 minutes longer than the native oxyntomodulin, it still has a very short in vivo half-life of 1.7 hr and its administration dose is also as high as several mg/kg.
  • oxyntomodulin or derivatives thereof have disadvantages of daily administration of high dose due to the short half-life and low efficacy.
  • the present inventors have developed an oxyntomodulin derivative prepared by modifying the amino acid sequence of native oxyntomodulin in order to enhance its therapeutic effects on obesity and to reduce its administration dose. As a result, they found that the oxyntomodulin derivative shows more excellent activities on a glucagon receptor and a GLP-1 receptor than native oxyntomodulin, thereby completing the present invention.
  • An object of the present invention is to provide a novel peptide showing excellent therapeutic effects on obesity.
  • Another object of the present invention is to provide a composition for the prevention or treatment of obesity, comprising the peptide.
  • Still another object of the present invention is to provide a method for preventing or treating obesity by administering the peptide or the composition to a subject.
  • Still another object of the present invention is to provide use of the peptide in the preparation of drugs for the prevention or treatment of obesity.
  • the novel peptide of the present invention reduces food intake, suppresses gastric emptying, and facilitates lipolysis without side-effects, and also shows excellent receptor-activating effects. Thus, it can be widely used in the treatment of obesity with safety and efficacy.

Description

NOVEL OXYNTOMODULIN DERIVATIVES AND PHARMACEUTICAL COMPOSITION FOR TREATING OBESITY COMPRISING THE SAME
The present invention relates to a novel peptide showing excellent activities on a glucagon like peptide-1 receptor and a glucagon receptor greater than native oxyntomodulin, and a composition for the prevention or treatment of obesity comprising the peptide as an active ingredient.
Recently, economic growth and changes in lifestyle are leading to changes in eating habits. The main causes of rising overweight and obesity rates in contemporary people are consumption of high-calorie foods such as fast foods and lack of exercise. World Health Organization (WHO) estimates that more than 1 billion people worldwide are overweight and at least 300 million of them are clinically obese. In particular, 250,000 people die each year in Europe and more than 2.5 million people worldwide die each year as a result of being overweight (World Health Organization, Global Strategy on Diet, Physical Activity and Health, 2004).
Being overweight and obese increases blood pressure and cholesterol levels to cause occurrence or exacerbation of various diseases such as cardiovascular disease, diabetes, and arthritis, and are also main causes of rising incidence rates of arteriosclerosis, hypertension, hyperlipidemia or cardiovascular disease in children or adolescents as well as in adults.
Obesity is a severe condition that causes various diseases worldwide. It is thought to be overcome by individual efforts, and it is also believed that obese patients lack self-control. However, it is difficult to treat obesity, because obesity is a complex disorder involving appetite regulation and energy metabolism. For the treatment of obesity, abnormal actions associated with appetite regulation and energy metabolism should be treated together with efforts of obese patients. Many attempts have been made to develop drugs capable of treating the abnormal actions. As the result of these efforts, drugs such as Rimonabant (Sanofi-Aventis), Sibutramin (Abbott), Contrave (Takeda), and Orlistat (Roche) have been developed, but they have the disadvantages of serious adverse effects or very weak anti-obesity effects. For example, it was reported that Rimonabant (Sanofi-Aventis) shows a side-effect of central nerve disorder, Sibutramine (Abbott) and Contrave (Takeda) show cardiovascular side-effects, and Orlistat (Roche) shows only 4 kg of weight loss when taken for 1 year. Unfortunately, there are no therapeutic agents for obesity which can be safely prescribed for obese patients.
Many studies have been made to develop therapeutic agents for obesity which do not have the problems of the conventional anti-obesity drugs. Recently, glucagon derivatives have received much attention. Glucagon is produced by the pancreas when the level of glucose in the blood drops resulting from other medications or diseases, hormone or enzyme deficiencies. Glucagon stimulates glycogen breakdown in the liver, and facilitates glucose release to raise blood glucose levels to a normal range. In addition to the effect of increasing the blood glucose level, glucagon suppresses appetite and activates hormone-sensitive lipase(HSL) of adipocytes to facilitate lipolysis, thereby showing anti-obesity effects. One of the glucagon derivatives, glucagon like peptide-1 (GLP-1) is under development as a therapeutic agent for hyperglycemia in patients with diabetes, and it functions to stimulate insulin synthesis and secretion, to inhibit glucagon secretion, to slow gastric emptying, to increase glucose utilization, and to inhibit food intake. Exendin-4 is isolated from lizard venom that shares approximately 50% amino acid homology with GLP-1 and is also reported to activate the GLP-1 receptor, thereby ameliorating hyperglycemia in patients with diabetes. However, anti-obesity drugs including GLP-1 are reported to show side-effects such as vomiting and nausea.
As an alternative to GLP-1, therefore, much attention has been focused on oxyntomodulin, a peptide derived from a glucagon precursor, pre-glucagon that binds to the receptors of two peptides, GLP-1 and glucagon. Oxyntomodulin represents a potent anti-obesity therapy, because it inhibits food intake like GLP-1, promotes satiety, and has a lipolytic activity like glucagon.
Based on the dual function of the oxyntomodulin peptide, it has been actively studied as a drug for the treatment of obesity. For example, Korean Patent No. 925017 discloses a pharmaceutical composition including oxyntomodulin as an active ingredient for the treatment of overweight human, which is administered via an oral, parenteral, mucosal, rectal, subcutaneous, or transdermal route. However, it has been reported that this anti-obesity drug including oxyntomodulin has a short in vivo half-life and weak therapeutic efficacy, even though administered at a high dose three times a day. Thus, many efforts have been made to improve the in vivo half-life or therapeutic effect of oxyntomodulin on obesity by its modification.
For example, a dual agonist oxyntomodulin (Merck) is prepared by substituting L-serine with D-serine at position 2 of oxyntomodulin to increase a resistance to dipeptidyl peptidase-IV (DPP-IV) and by attaching a cholesterol moiety at the C-terminal to increase the blood half-life at the same time. ZP2929 (Zealand) is prepared by substituting L-serine with D-serine at position 2 to enhance resistance to DPP-IV, substituting arginine with alanine at position 17 to enhance resistance to protease, substituting methionine with lysine at position 27 to enhance oxidative stability, and substituting glutamine with aspartic acid and alanine at positions 20 and 24 and asparagine with serine at position 28 to enhance deamidation stability. However, even though the half-life of the dual agonist oxyntomodulin (Merck) was enhanced to show half-life 8~12 minutes longer than the native oxyntomodulin, it still has a very short in vivo half-life of 1.7 hr and its administration dose is also as high as several mg/kg. Unfortunately, oxyntomodulin or derivatives thereof have disadvantages of daily administration of high dose due to the short half-life and low efficacy.
Accordingly, the present inventors have developed an oxyntomodulin derivative prepared by modifying the amino acid sequence of native oxyntomodulin in order to enhance its therapeutic effects on obesity and to reduce its administration dose. As a result, they found that the oxyntomodulin derivative shows more excellent activities on a glucagon receptor and a GLP-1 receptor than native oxyntomodulin, thereby completing the present invention.
An object of the present invention is to provide a novel peptide showing excellent therapeutic effects on obesity.
Another object of the present invention is to provide a composition for the prevention or treatment of obesity, comprising the peptide.
Still another object of the present invention is to provide a method for preventing or treating obesity by administering the peptide or the composition to a subject.
Still another object of the present invention is to provide use of the peptide in the preparation of drugs for the prevention or treatment of obesity.
Unlike native oxyntomodulin, the novel peptide of the present invention reduces food intake, suppresses gastric emptying, and facilitates lipolysis without side-effects, and also shows excellent receptor-activating effects. Thus, it can be widely used in the treatment of obesity with safety and efficacy.

More preferably, the peptide of the present invention may be selected from the group consisting of the peptides of SEQ ID NOs. 1 to 31. Much more preferably, the peptide of the present invention may be an oxyntomodulin derivative described in Table 1 of Example 2-1.
Oxyntomodulin has activities of two peptides, GLP-1 and glucagon. GLP-1 decreases blood glucose, reduces food intake, and suppresses gastric emptying, and glucagon increases blood glucose, facilitate lipolysis and decreases body-weight by increasing energy metabolisms. Different biological effects of two peptides can cause undesired effects like increasing blood glucose if glucagon shows more dominant effect than GLP-1, or causing nausea and vomiting if GLP-1 shows more dominant effect than glucagon. Therefore, the oxyntomodulin derivatives of the present invention are not only aimed to increase these activities, for example, amino acids at position 1 and 11 of oxyntomodulin which suppress the activity of glucagon, may be modified for balancing the activity ratios of glucagon and GLP-1.
The present inventors performed in vitro experiments to demonstrate that the peptide of the present invention shows excellent activities on the GLP-1 receptor and the glucagon receptor, compared to oxyntomodulin. Thus, it is suggested that the peptide of the present invention activates the GLP-1 receptor and the glucagon receptor to show more excellent therapeutic effects on obesity than the conventional oxyntomodulin. In addition, its inhibitory effects on in vivo food intake were examined, and it shows more excellent inhibitory effects on food intake than the conventional oxyntomodulin (FIG. 1).
It is apparent to those skilled in the art that when the oxyntomodulin derivatives of the present invention are modified using the typical techniques, including modification with polymers such as PEG and sugar chain or fusion with albumin, transferrin, fatty acid, and immunoglobulin in order to improve the therapeutic effects of the oxyntomodulin derivatives, they will show superior therapeutic effects to native oxyntomodulin. Therefore, the modified oxyntomodulin derivatives are also included in the scope of the present invention.
In another aspect, the present invention provides a polynucleotide encoding the peptide.
The term "homology", as used herein for the polynucleotide, indicates sequence similarity between wild-type amino acid sequences or wild-type nucleotide sequences, and includes a gene sequence that is 75% or higher, preferably 85% or higher, more preferably 90% or higher and even more preferably 95% or higher identical to the polynucleotide sequence encoding the peptide. The homology evaluation may be done with the naked eye or using a commercially available program. Using a commercially available computer program, the homology between two or more sequences may be expressed as a percentage (%), and the homology (%) between adjacent sequences may be evaluated. The polynucleotide encoding the peptide is inserted into a vector and expressed so as to obtain a large amount of the peptide.

Example 2-2: Test on in vitro activity of oxyntomodulin derivatives
In order to measure anti-obesity efficacies of the oxyntomodulin derivatives synthesized in Example 2-1, cell activity was measured in vitro using the cell lines prepared in Examples 1-1 and 1-2.
The cell lines were those prepared by transfecting CHO (Chinese Hamster Ovary) to express human GLP-1 receptor gene and glucagon receptor gene, respectively. Thus, they are suitable to measure GLP-1 and glucagon activities. Therefore, the activity of each oxyntomodulin derivative was measured using each transformed cell line.
Specifically, each cell line was sub-cultured twice or three time a week, and aliquoted in each well of a 96-well plate at a density of 1 X 105, followed by cultivation for 24 hours.
The cultured cells were washed with KRB buffer and suspended in 40 ml of KRB buffer containing 1 mM IBMX, and left at room temperature for 5 minutes. Oxyntomodulin (SEQ ID NO. 1) and oxyntomodulin derivatives (represented by SEQ ID NOs. 2-6, 8, 10-13, 17, 18, 23-25, 27-30 and 31) were diluted from 1000 nM to 0.02 nM by 5-fold serial dilution, and each 40 mL thereof was added to the cells, and cultured at 37°C for 1 hour in a CO2 incubator. Then, 20 mL of cell lysis buffer was added for cell lysis, and the cell lysates were applied to a cAMP assay kit (Molecular Device, USA) to measure cAMP concentrations. EC50 values were calculated therefrom, and compared to each other. EC50 values are shown in the following Table 2.

As shown in Table 2, there were oxyntomodulin derivatives showing excellent in vitro activities and different ratios of activities on GLP-1 receptor and glucagon receptor, compared to native oxyntomodulin of SEQ ID NO. 1.
It is known that oxyntomodulin activates both the GLP-1 receptor and glucagon receptor to suppress appetite, facilitate lipolysis, and promote satiety, thereby showing anti-obesity effects. The oxyntomodulin derivatives according to the present invention show higher in vitro activities on both the GLP-1 receptor and glucagon receptor than the wild-type oxyntomodulin, and therefore can be used as a therapeutic agent for obesity with higher efficacies than the known oxyntomodulin.
Example 3. Test on in vivo activity of oxyntomodulin derivatives
In order to measure in vivo therapeutic activity of oxyntomodulin derivatives, changes in food intake by administration of oxyntomodulin derivatives were examined in ob/ob mouse using native oxyntomodulin as a control.
Specifically, obese diabetic ob/ob mice, commonly used to test the efficacies of therapeutic agents for obesity and diabetes, were fasted for 16 hours, and administered with 1 or 10 mg/kg of oxyntomodulin, or 0.02, 0.1, 1 or 10 mg/kg of the oxyntomodulin derivative of SEQ ID NO. 2. Then, food intake was examined for 2 hours (FIG. 1). FIG. 1 is a graph showing changes in food intake according to administration dose of oxyntomodulin or oxyntomodulin derivative. As shown in FIG. 1, administration of 1 mg/kg of oxyntomodulin derivative showed more excellent inhibitory effects on food intake than administration of 10 mg/kg of oxyntomodulin.
Taken together, the oxyntomodulin derivatives of the present invention have much higher anti-obesity effects than the wild-type oxyntomodulin, even though administered at a lower dose, indicating improvement in the problems of the wild-type oxyntomodulin that shows lower anti-obesity effects and should be administered at a high dose three times a day.
