Treatment of diabetes mellitus, complications of diabetic patients with diabetes, diabetes, obesity, hyperlipidemia, fatty liver, coronary artery disease, osteoporosis, polycystic ovary syndrome N, N-dimethyl imidodicarbonimiddia, a very effective therapeutic agent for the prevention and treatment of complications due to the neutral lipid lowering effect as a causative agent, and for the prevention and treatment of cancer, myalgia, muscle cytotoxicity and rhabdomyolysis, which lack p53 gene Novel crystalline acid addition salts of meads, methods for preparing the same and pharmaceutical compositions thereof to be.
N,N-디메틸 이미도디카르본이미딕 디아미드는 일반명이 메트포르민(Metformin)으로, 인슐린 비의존형 당뇨병 치료제로 당뇨병 환자가 이 약물을 복용 시 모든 경구용 당뇨병 약 중에서는 혈당 강하 작용이 가장 우수하고 합병증 발생 및 악화 예방력이 가장 우수한 비구아니드계 약물이다.N, N-dimethyl imidodicarbonimidic diamide, commonly known as metformin, is an insulin-independent diabetes treatment that is the most effective hypoglycemic and complication of all oral diabetes medications when diabetic patients take this drug. It is a biguanide drug with the best prevention against occurrence and deterioration.
모든 경구용 당뇨병 치료제 중에서 메트포르민만이 1차 선택약으로서 특징을 지니고 있다는 사실은 여러 논문에서 제시되어 있다. 특히 메트포르민의 약효가 AMPK(AMP-activated protein kinase)를 활성화시킨다는 사실이 입증됨으로써 그 임상 효과의 정당성을 입증해주게 된 것이다. AMPK는 탄수화물 대사와 지질 대사를 생리적으로 조절하는 핵심 효소이며 메트포르민은 이 효소를 활성화시켜 고혈당을 정상화시키고 지질 상태를 개선시키며 월경 불순, 배란 및 임신을 정상화시키고, 지방간을 치료하며 유전자 p53(Tumor protein p53)이 결여된 암의 예방 및 치료가 보고되었다.Of all the oral diabetes treatments, metformin is the only option that has been characterized in several papers. In particular, it was proved that the effect of metformin activates AMP-activated protein kinase (AMPK), thereby validating its clinical effect. AMPK is a key enzyme that physiologically regulates carbohydrate and lipid metabolism, and metformin activates this enzyme to normalize hyperglycemia, improve lipid status, normalize menstrual irregularities, ovulation and pregnancy, treat fatty liver, and gene p53 (Tumor protein) prevention and treatment of cancers lacking p53) have been reported.
펜실바니아 의대 암 연구소(Abramson Cancer Center)가 암 전문지를 통해 발표한 바에 따르면 p53 유전자가 결여된 암의 예방과 치료에 AMPK 효소 활성화제인 메트포르민이 효과가 있다고 보고하였다[Monica Buzzai, et al. Syntemic Treatment with the Antidiabetic Drug Metformin Selectively Impairs p53-Deficient Tumor Cell Growth, Cancer Res 2007; 67:(14). July 15, 2007]. The Cancer Cancer Journal of the Pennsylvania School of Medicine reported that metformin, an AMPK enzyme activator, was effective in the prevention and treatment of cancers lacking the p53 gene [Monica Buzzai, et al. Syntemic Treatment with the Antidiabetic Drug Metformin Selectively Impairs p53-Deficient Tumor Cell Growth, Cancer Res 2007; 67: (14). July 15, 2007].
즉, 인체가 불리한 조건에 처하게 되면 이에 적응하는 에너지 대사를 전개시켜 주는 AMPK 효소를 메트포르민이 활성화시켜 당과 지질을 조절하고 암세포를 제거한다. In other words, when the human body is in an adverse condition, metformin activates the AMPK enzyme, which develops energy metabolism that adapts to it, regulates sugar and lipids and removes cancer cells.
p53 유전자는 손상된 세포나 필요 없는 세포 그리고 노화세포를 자살하게 하는데, 암세포가 변이되면 이 p53 유전자가 결여되어 난치성 암세포가 된다.The p53 gene causes suicide of damaged or unwanted cells and senescent cells. When the cancer cell is mutated, the p53 gene is missing and becomes a refractory cancer cell.
이 p53 유전자가 결여된 난치성 암세포의 AMPK 효소를 메트포르민이 활성화시켜 대사 경로가 바뀌게 되고 바뀐 대사 경로에 적응치 못하여 암세포는 사멸한다는 것이 실험으로 입증되었다.Experiments have demonstrated that metformin activates the AMPK enzyme of refractory cancer cells lacking the p53 gene, altering metabolic pathways and killing cancer cells because they cannot adapt to the altered metabolic pathways.
이 발표를 통해 밝혀진 바는 이 p53 유전자는 AMPK라는 에너지 대사 조절 효소를 이용하여 암을 제거하고 장수를 유지시킨다는 점이다.The announcement revealed that the p53 gene uses an energy metabolic regulator called AMPK to remove cancer and maintain longevity.
메트포르민은 AMPK 효소를 활성화시켜 당과 지질 대사를 정상화하는 약물이며 p53 유전자가 결여된 암에 메트포르민을 투여하면 암세포의 에너지 대사 경로가 바뀌게 되며 메트포르민의 투여량에 비례하여 항암 작용이 증가하며, 메트포르민은 당뇨병을 치료하는 정상 용량으로 암을 치료하는데 효과적임이 밝혀져 있다.Metformin is a drug that normalizes sugar and lipid metabolism by activating the AMPK enzyme, and metformin in cancers lacking the p53 gene alters the energy metabolic pathways of cancer cells and increases anticancer activity in proportion to the dose of metformin. It has been found to be effective in treating cancer at normal doses for treating diabetes.
또한 미국 보스턴 소재 메디컬센터(Beth Israel Deaconess Medical center)의 연구진이 의학 전문지를 통해 발표한 바에 따르면 PGC-1α 활성제인 메트포르민은 근육통, 근육세포 손상, 나아가 횡문근융해(rhabdomyolysis)라는 심각한 부작용을 예방하는데 효과적임이 밝혀져 있다[Jun-ichi Hanai, et al. The muscle-specific ubiquitin ligase atroigin-1/MAFbx mediates statin-induced muscle toxicity, J. Clin. Invest. 117:3940-3951(2007)].In addition, researchers from the Beth Israel Deaconess Medical center in Boston, USA, reported in a medical journal that metformin, a PGC-1α activator, is effective in preventing serious side effects such as muscle pain, muscle cell damage, and even rhabdomyolysis. It is found that Jun-ichi Hanai, et al. The muscle-specific ubiquitin ligase atroigin-1 / MAFbx mediates statin-induced muscle toxicity, J. Clin. Invest. 117: 3940-3951 (2007).
또한 Atrogin-1 유전자의 발현은 근육통, 근육세포 손상, 나아가 횡문근융해(rhabdomyolysis)의 근육독성을 일으키지만, 메트포르민은 PGC-1α 전사인자 활성으로 인해 Atrogin-1 유전자의 발현을 억제하여 Atrogin-1 유전자의 발현증가로 인한 근육장해를 억제하고 예방한다.In addition, the expression of the Atrogin-1 gene causes myalgia, muscle cell damage and even rhabdomyolysis, but metformin inhibits the expression of the Atrogin-1 gene due to PGC-1α transcription factor activity. Inhibits and prevents muscle damage caused by increased expression of
약학적으로 메트포르민은 유리염기 형태인 것이 유용하지만, 안정성이 떨어지는 단점이 있기 때문에 약제학적으로 허용 가능한 산부가염 형태로 투여되고 있다.Pharmaceutically, metformin is useful in the free base form, but because of the disadvantage of poor stability, it is administered in the form of a pharmaceutically acceptable acid addition salt.
대한민국특허등록 제90,479호에는 약제학적으로 허용 가능한 염의 형태로 제조하는데 있어서는 (1) 우수한 용해도; (2) 우수한 안정성; (3) 비흡습성; (4) 정제 제형으로서의 가공성과 같은 네 가지 물리화학적 기준을 충족시킬 수 있어야 한다고 기술하고 있다. 약제학적으로 허용되는 산부가염으로서 네 가지 조건을 모두 충족시키기란 매우 어려운 면이 있다.Korean Patent Registration No. 90,479 discloses (1) excellent solubility in preparing in the form of a pharmaceutically acceptable salt; (2) good stability; (3) nonhygroscopic; (4) states that four physicochemical criteria such as processability as tablet formulations should be met. As a pharmaceutically acceptable acid addition salt, it is very difficult to meet all four conditions.
메트포르민 염산염이 아닌 그 외에 부가 염에 대한 연구는 예전부터 이루어져 왔다. CN 1962661A에서는 임상적으로 항악성(抗惡性) 빈혈인자로 쓰이는 엽산을 이용한 메트포르민 엽산염에 대한 특허를 출원했었고, WO 2005/033067에서 고지혈증, 고혈당증 치료에 쓰이는 메트포르민 1,2,6,7,8,8a-헥사하이드로-베타,감마,6-트리하이드록시-2-메틸-8-[(2s)-2-메틸-1-옥소부톡시]-,(베타R,감마R,1S,2S,6S,8S,8aS)-1-나프탈렌헵타산염에 대한 특허를 출원하였다. US 3,957,853에서 메트포르민 아세틸살리실산염에 대한 특허를 출원하였으며, US 4,028,402에서 비구아니드계 화합물의 새로운 부가 염에 대한 특허를 출원하였다. US 4,080,472에서는 메트포르민 클로피브린산염의 당뇨병 관련 질환에 대한 특허를 출원하였으며, US 6,031,004에서는 메트포르민의 푸마르산염, 석신산염, 말레인산염에 의한 의약 조성물과 그의 용도에 대한 내용을 나타내고 있으며, US 4,835,184에서는 p-클로로-페녹시아세트산염, US 3,903,141에서는 아다만탄염에 대해 개시하고 있다. Other studies on addition salts other than metformin hydrochloride have been made for some time. CN 1962661A has applied for a patent on metformin folate using folic acid, which is used clinically as an anti-malignant anemia factor, and in WO 2005/033067 metformin 1,2,6,7,8, used to treat hyperlipidemia and hyperglycemia. 8a-hexahydro-beta, gamma, 6-trihydroxy-2-methyl-8-[(2s) -2-methyl-1-oxobutoxy]-, (betaR, gammaR, 1S, 2S, 6S , 8S, 8aS) -1-naphthaleneheptalate. A patent for metformin acetylsalicylate in US 3,957,853 is filed and a patent for a new addition salt of biguanide-based compound in US 4,028,402. US 4,080,472 has filed a patent for a diabetes related disease of metformin clofibrate, US 6,031,004 discloses a pharmaceutical composition of fumarate, succinate and maleate of metformin and its use, and US Pat. Chloro-phenoxyacetate, US 3,903,141 discloses adamantane salts.
이처럼 메트포르민 부가 염에 대한 연구는 꾸준히 진행되어 왔지만, 지금까지 메트포르민은 오로지 염산염으로서의 약물만이 허가되어 인슐린-비의존성 당뇨병(non-insulin dependent diabetes mellitus) 치료제로 널리 처방되고 있으며, 메트포르민 염산염의 통상적인 투여량은 하루 최대 2550 mg으로 식사와 함께 500 mg, 750 mg 정제를 하루에 2 ~ 3회에 걸쳐서 투여한다. 그러나 이러한 메트포르민 염산염 및 그 외의 부가염은 약리학적 효과를 위해 용해도, 안정성, 비흡습성, 부착방지특성 등의 물리화학적 성질의 개선 및 독성의 저하가 요구되고 있다. Although studies on metformin addition salts have been steadily progressed, to date, metformin has been approved only as a hydrochloride drug and is widely prescribed as a drug for treating non-insulin dependent diabetes mellitus. The dosage is up to 2550 mg per day, with 500 mg, 750 mg tablets taken two to three times daily with meals. However, such metformin hydrochloride and other addition salts are required for improvement of physicochemical properties such as solubility, stability, non-hygroscopicity, anti-adhesion properties, and lowering of toxicity for pharmacological effects.
한편, 기존특허(미국특허 4,080,472)에서는 메트포르민 유리염기를 합성할 때, 메트포르민 염산염에서 염산을 제거하기 위해서 이온교환수지 칼럼을 사용하여 어렵게 생산하고, 용매를 가열 환류하고 뜨거운 상태에서 여과를 하는 혹독한 생산조건을 요구한다. 그러므로 특별한 설비 없이 일반적인 생산설비에서 합성이 가능하도록 단순하게 공정을 개선하여 산업이용가능성을 높여 보다 낮은 단가로 메트포르민의 유기산염을 합성할 수 있어 약제학적으로 허용 가능한 염을 제조하는데 사용되는 다양한 산과의 반응에 이용할 수 있는 방법이 요구되고 있다.Meanwhile, in the existing patent (US Pat. No. 4,080,472), when synthesizing metformin free base, it is difficult to produce hydrochloric acid from metformin hydrochloride by using an ion exchange resin column, and the solvent is heated to reflux and filtered in a hot state. Requires a condition. Therefore, it is possible to synthesize organic acid salt of metformin at a lower cost by simply improving the process so that it can be synthesized in a general production facility without special equipment and increasing the industrial usability, so that it can be combined with various acids used to prepare pharmaceutically acceptable salts. There is a demand for a method that can be used for the reaction.
본 발명의 목적은 비흡습성, 용해도, 안정성, 정제 제형으로서의 가공성 등의 물리화학적 성질이 우수하고, 독성이 낮으며, 당뇨, 비만증, 고혈압, 고지혈증, 지방간, 관상동맥질환, 골다공증 또는 다낭성 난소증후군이 복합적으로 나타나는 대사성 증후군자의 당뇨병 및 이의 합병증, p53 유전자가 결여된 암, 근육통, 근육세포 독성 및 횡문근융해의 예방 및 치료에 유효한 약제학적으로 허용 가능한 메트포르민 니코틴산염 및 그의 제조방법을 제공하는데 있다.The object of the present invention is to have excellent physicochemical properties such as non-hygroscopicity, solubility, stability, processability as a tablet formulation, low toxicity, diabetes, obesity, hypertension, hyperlipidemia, fatty liver, coronary artery disease, osteoporosis or polycystic ovary syndrome.

최근에 알려진 메트포르민에 관한 논문에 의하면, Josie M M Evans는 2형 당뇨 환자에게 메트포르민 치료를 받을 시 그렇지 않은 환자에 비해 암 발병률이 낮다는 연구결과를 내놓았다[Josie MM, Evans et al. BMJ. 2005, 330, 1304-1305]. 또한 Samantha L. Bowker는 메트포르민을 복용하는 2형 당뇨 환자가 술포닐우레아 복용하거나 인슐린을 투약하는 환자 보다 암과 관련된 사망률이 낮다고 보고하였다[Samantha L et al. Diabetes Care. 2006, 29, 254-258].According to a recently published paper on metformin, Josie M M Evans has shown a lower incidence of cancer in patients with type 2 diabetes than those who do not receive metformin [Josie MM, Evans et al. BMJ. 2005, 330, 1304-1305. Samantha L. Bowker also reported that patients with type 2 diabetes who take metformin have lower cancer-related mortality than patients who take sulfonylureas or take insulin [Samantha L et al. Diabetes Care. 2006, 29, 254-258.
또한, 니코틴산은 최근에 이르러 당뇨병 환자에서 특히 높아지는 중성 지질의 저하약으로서 그리고 좋은 지질인 HDL(고밀도 지단백질(High-density lipoprotein))을 증가시키는 약으로서 널리 인정되기 시작했으며[Canner PL, Berge KG, Wenger NK, et al. Fifteen year mortality in Coronary Drug Project patients:long-term benefit with niacin. J. Am. Coll. Cardiol. 8 (6): 1245-1255(1986)], 메트포르민이 지닌 중성 지질저하 작용은 오래전부터 임상계에 널리 알려진 메트포르민의 본질적 특성이다. 뿐만 아니라 니코틴산은 당뇨병, 고지혈증, 고혈압 등으로 인해 나타나는 뇌신경 장애와 유전자 장애까지도 정상화시키는 병태 개선 과정에 핵심적으로 작용함이 밝혀졌다[The journal of pharmacology and experimental therapeutics; 324; 883-893(2008), NAD and vitamin B3: From metabolism to therapeutics; Anthony A. Sauve Cornell. Medical college of cornell university]. 따라서 메트포르민에 니코틴산염으로 한 본 발명의 새로운 메트포르민 니코틴산염은 당뇨병자의 합병증의 근본 핵심 원인 물질인 중성 지질 저하 작용을 매우 증강시켜주는 당뇨병 약이 될 수 있다.In addition, nicotinic acid has recently become widely recognized as a drug for increasing neutral lipids, which is particularly high in diabetics, and as a drug that increases HDL (High-density lipoprotein), a good lipid [Canner PL, Berge KG, Wenger NK, et al. Fifteen year mortality in Coronary Drug Project patients: long-term benefit with niacin. J. Am. Coll. Cardiol. 8 (6): 1245-1255 (1986)], metformin's neutral lipid lowering action is an essential characteristic of metformin, which has long been widely known in the clinical field. In addition, nicotinic acid has been found to play a key role in the pathological process of normalizing neurological and genetic disorders caused by diabetes, hyperlipidemia and hypertension [The journal of pharmacology and experimental therapeutics; 324; 883-893 (2008), NAD and vitamin B3: From metabolism to therapeutics; Anthony A. Sauve Cornell. Medical college of cornell university]. Therefore, the new metformin nicotinate of the present invention made of metformin nicotinate can be a diabetic drug that greatly enhances the neutral lipid lowering action, which is a fundamental core cause of complications of diabetics.
본 발명에 따르는 메트포르민 니코틴산염은 기존에 당뇨병 치료제로서 사용되었던 메트포르민 염산염보다 우수한 혈당 강하 효과, 특히 공복 시 뿐만 아니라 식후 혈당 강하에 매우 효과적이고 인슐린 감수성을 증가시키는 효과를 나타낸다. Metformin nicotinate according to the present invention is superior to metformin hydrochloride, which has previously been used as a diabetic agent, and is particularly effective on fasting as well as postprandial blood sugar drop and increases insulin sensitivity.
또한 본 발명에 따르는 메트포르민 니코틴산염의 제조방법은 단순하고 특별한 설비 없이 진행 가능하도록 공정을 확립하였다. 또한, 공정을 개선하여 산업이용가능성을 높여 보다 낮은 단가로 메트포르민의 신규염을 합성할 수 있다.
