Abstract

본 발명은 신규 저심독성 안트라사이클린 유도체 및 이를 함유하는 항종양제에 관한 것이다. 퀴논 화학구조를 가진 항암항생물질은 생체내 순환적 산화환원 반응에서 계속적으로 슈퍼옥시드와 같은 산소라디칼을 생성하므로, 퀴논 리닥타제의 기능을 제어하는 방안은 효율적으로 산소라디칼 생성억제 방안이 되어, 안트라사이클린계 항암항생제의 부작용을 줄이는 중요한 방안이 될 수 있음에 착안하여 본 발명자는 심근 독성의 요인이 되는 라디칼생성은 NAD/NADH 비의 보정을 통하여 조절할 수 있음을 알았다. 따라서 본 발명에서는 세포내 NAD/NADH 비의 균형을 보완하여 산소라디칼 생성효소계의 활성을 제어하는 신규 저심독성 항암제인 안트라사이클린계 유도체을 발명하였다. 신규 안트라사이클린 유도체는 공지의 안트라사이클린 항암약물의 14번위치에 L-아스파르테이트 혹은 피루베이트와 에스테르결합으로 제조하고 이들의 화학구조 및 물성과 안정성시험, 심장독성시험, 항암력 평가시험을 실시하였다. 시험결과 본 발명화합물은 안정성이 우수하고 공지의 안트라사이클린계 항암물질과 유사한 항암력을 가지면서도 심장독성이 매우 경감된 우수한 항암약물임이 확인되었다. 이와같은 발명은 심장독성이 경감된 신규 안트라사이클린 유도체를 함유하는 암치료용 약제로 이용될 수 있다.The present invention relates to novel low cardiotoxic anthracycline derivatives and antitumor agents containing the same. Since anti-cancer antibiotics with quinone chemical structure continuously produce oxygen radicals such as superoxide in circulating redox reactions in vivo, the method of controlling the function of quinone reddactase becomes an efficient method of inhibiting oxygen radical generation. In view of the fact that it can be an important way to reduce the side effects of anthracycline-based anticancer antibiotics, the present inventors have found that radical generation, which is a factor of myocardial toxicity, can be regulated through correction of the NAD / NADH ratio. Therefore, the present invention invented an anthracycline derivative, a novel low cardiotoxic anticancer agent that controls the activity of oxygen radical synthase system by compensating the balance of intracellular NAD / NADH ratio. The novel anthracycline derivatives are prepared by ester-bonding with L-aspartate or pyruvate at position 14 of known anthracycline anticancer drugs, and their chemical structure and physical properties, stability tests, cardiotoxicity tests, and anticancer evaluation tests are performed. It was. As a result of the test, it was confirmed that the compound of the present invention is an excellent anticancer drug having excellent stability and anticancer activity similar to a known anthracycline-based anticancer substance, and having very reduced cardiotoxicity. This invention can be used as a drug for the treatment of cancer containing a novel anthracycline derivative with reduced cardiotoxicity.

Description

신규 안트라사이클린 유도체 및 제조방법New anthracycline derivatives and preparation methods

본 발명은 다음 일반식(Ⅰ)으로 표시되는 신규 안트라사이클린(Athracycline) 유도체 및 이를 함유하는 항종양제에 관한 것이다.The present invention relates to a novel anthracycline derivative represented by the following general formula (I) and an anti-tumor agent containing the same.

(Ⅰ)(Ⅰ)

상기식에서 R1와 R4은 수소원자 혹은 메톡시기 혹은 수산기이고, R는 L-아스파르테이트기 혹은 피루베이트기, R3는 수소원자 혹은 불소를 나타낸다.Wherein R 1 and R 4 represent a hydrogen atom or a methoxy group or a hydroxyl group, R represents an L-aspartate group or pyruvate group, and R 3 represents a hydrogen atom or fluorine.

또한 본 발명은 상기 아스파르테이트- 및 피루베이트-안트라사이클린 글리코사이드 유도체의 제조방법과 이러한 신규 화합물을 유효성분으로 하는 항종양제에 관한 것이다. 안트라사이클린 종류의 물질로서 종래 방사선균의 배양액에서 얻을 수 있는 로도마이신, 다우노마이신 및 아드리아마이신은 그의 화학 구조가 결정된 이후 오랫동안 공지되어 왔으며, 특정의 대표적인 안트라사이클린(예: 다우노마이신, 아드리아마이신, 아클라시노마이신, 4'-에피-아드리아마이신, 4'-메톡시아아드리아마이신, 4'-데옥시아드리아마이신과 이다루비신)은 이미 넓은 항암 스펙트럼을 가지고 암화학요법제로서 임상적 종양치료에 사용해온 것은 공지되어 있다.The present invention also relates to a method for producing the aspartate- and pyruvate-anthracycline glycoside derivatives and an anti-tumor agent comprising the novel compound as an active ingredient. Rhodomycin, daunomycin and adriamycin, which can be obtained from cultures of conventional radiation bacteria as anthracycline species, have long been known since their chemical structures have been determined, and certain representative anthracyclines (eg daunomycin, adriamycin) , Aclacinomycin, 4'-epi-adriamycin, 4'-methoxyadriamycin, 4'-deoxyadriamycin and idarubicin) already have a broad anticancer spectrum and are a clinical chemotherapy agent for cancer It is known to have been used for.

이러한 공지된 안스라사이클린 화학구조을 가진 퀴논계 항암항생제들은 백혈병, 악성임파종을 포함하여 많은 종류의 악성종양에 유효한 광범위하고 강력한 항암작용을 나타내지만, 심근장해, 골수억제, 탈모 등의 부작용을 수반하며, 특히 심한 심장독성이 자주 출현하기 때문에 임상적인 사용에 있어 많은 제한을 받고 있다. 이러한 심장독성은 급성 또는 만성으로 출현하여 심수축기능 저하, 부정맥, 저혈압 등을 일으키고 심하면 심부전증에 의한 사망까지도 초래한다.These quinone-based anticancer antibiotics with the known anthracycline chemical structure exhibit a wide range of potent anticancer effects effective against many types of malignancies including leukemia and malignant lymphomas, but have side effects such as cardiomyopathy, myelosuppression, and hair loss. In particular, severe cardiotoxicity is frequently present, which limits the clinical use. This cardiotoxicity can be acute or chronic, causing cardiac contractility, arrhythmia, hypotension, and even death due to heart failure.

본 발명자들는 이들 화합물의 심장독성을 경감시키기 위해 아스파르트산과 그 염이 생체내 NADH/NAD 비율을 조절함으로써 독소루비신에 의한 심독성을 경감시킬 수있다는 선행 발명특허(한국특허출원번호 94-012769)에 근거하여 신규 아스파르테이트-안트라사이클리논 유도체를 발명하게 되었다. 또한 아스파르트산과 유사하게 생체내 NADH/NAD 비율을 조절할 수 있는 피루베이트와 결합된 안트라사이클린 유도체를 발명하였다. 따라서 본 발명의 주목적은 상기 구조식(Ⅰ)의 기존 다우노마이신,아드리아마이신, 카르미노마이신과 이다루비신등 안트라사이클린 글리코사이드계 항암제보다 심독성이 훨씬 경감된 신규 안트라사이클린 글리코사이드 항암제를 제공하는데 있다.The inventors of the present invention have found that aspartic acid and its salts can mitigate cardiotoxicity by doxorubicin by regulating the in vivo NADH / NAD ratio in order to alleviate the cardiotoxicity of these compounds (Korean Patent Application No. 94-012769). New aspartate-anthracyclinone derivatives have been invented. Also similar to aspartic acid was invented pyruvate-linked anthracycline derivatives that can regulate the in vivo NADH / NAD ratio. Accordingly, the main object of the present invention is to provide a novel anthracycline glycoside anticancer agent with much lower cardiotoxicity than anthracycline glycoside type anticancer agents such as daunomycin, adriamycin, carminomycin and idarubicin of the above formula (I). .

신규 안트라사이클린계 항암항생제는 약물의 대사과정에서 생성되는 산소라디칼이 특히 심근독성의 주요인으로 추정되고 있다. 이러한 산소라디칼이 야기하는 문제점을 해결하기 위해 독성이 다소 적은 새로운 항암항생물질의 유도체를 개발한다거나 항산화제 또는 라디칼제거 효소들의 병용요법이 제안되고 있지만 사용에 많은 제한을 받고 있다. 라디칼제거에 관련되는 효소들을 직접 사용하는 방법은 적절한 조건이 확립되어 있지 않고 라디칼 손상 억제에 이용되는 각종 항산화제들은 그들 자체가 높은 반응성을 가지고 있기 때문이다. 따라서 산소라디칼의 부작용을 감소시키는 효율적인 항산화제의 역할을 하면서도 안정성과 안전성이 높으며 약효 효능을 유지하는 새로운 차원의 신규 안트라사이클린계 항암약물의 개발이 절실히 필요하여 본 발명이 이루어지게 되었다. 본 발명의 또다른 목적은 상기 구조식(Ⅰ)의 신규 안트라사이클린 글리코사이드계 항암제를 제조하는 방법을 제공하는 것이다.Oxygen radicals produced during the metabolism of drugs are believed to be the main cause of myocardial toxicity. In order to solve the problems caused by oxygen radicals, the development of new anti-cancer antibiotic derivatives with less toxicity or a combination therapy of antioxidants or radical scavenging enzymes has been proposed, but the use of them has been limited. The direct use of enzymes involved in radical elimination is because the proper conditions are not established and the various antioxidants used to inhibit radical damage are themselves highly reactive. Therefore, while the role of an effective antioxidant to reduce the side effects of oxygen radicals, the development of a novel anthracycline-based anticancer drug of a high level of stability, safety and high efficacy is urgently needed to achieve the present invention. It is another object of the present invention to provide a method for preparing a novel anthracycline glycoside anticancer agent of the above formula (I).

화합물 6a을 아세토나이트릴에 녹인뒤, 같은 당량의 트리메틸 실릴요오드(Me3SiI)를 넣고, 10분동안 교반시켜서 카르보벤질옥시기 (cbz)기를 제거시켰다. 카르보벤질옥시기가 제거된 생성물을 메틸렌클로라이드에 녹이고, 3N 염산 수용액을 가하여 pH 3정도로 맞춘 뒤에 3시간 교반시켜서 생성물을 얻고, 생성물을 다시 메틸렌클로라이드에 녹여서 순수한 결정화합물 8a을 85%수율로 얻었다.After dissolving compound 6a in acetonitrile, the same equivalent of trimethyl silyl iodine (Me 3 SiI) was added and stirred for 10 minutes to remove the carbobenzyloxy group (cbz). The product from which the carbobenzyloxy group was removed was dissolved in methylene chloride, 3N hydrochloric acid aqueous solution was adjusted to pH 3, and stirred for 3 hours to obtain a product. The product was dissolved in methylene chloride to obtain pure crystalline compound 8a in 85% yield.

생물학적 활성Biological activity

본 발명에 의한 일반식(Ⅰ)의 화합물은 실험동물종양에 대하여 우수한 항종양 활성을 가지면서도, 그 항종양 활성이 공지의 안트라사이클린계 항암물질인 다우노마이신, 아드리아마이신등과 유사하지만 그 심장독성이 매우 경감된 것이 시험에 의해 확인되었다.The compound of general formula (I) according to the present invention has excellent antitumor activity against experimental animal tumors, but its antitumor activity is similar to that of known anthracycline anticancer substances such as daunomycin, adriamycin, and the like. Very low toxicity was confirmed by the test.

이들 신규 항암약물들에 의한 항종양 시험예는 다음과 같이 실시하였다.The antitumor test example by these new anticancer drugs was performed as follows.

< 시험예 1 ><Test Example 1>

실험동물종양에 대한 항종양 효과를 평가하기 위하여, 본 실험에 사용한 L1210생쥐 백혈병에 대한 항암제의 스크리닝법은 미국립 암연구소의 표준 스크리닝 방법으로 행하였다.(Geran,R.T, Cancer Chemother. Rep. part 3)In order to evaluate the antitumor effect on experimental animal tumors, the screening method of anticancer agent against L1210 mouse leukemia used in this experiment was performed by a standard screening method of the American Cancer Institute. (Geran, RT, Cancer Chemother.Rep. Part 3)

L1210복수육종 세포를 이식한 CDF생쥐의 복강으로 부터 L1210생쥐복수 육종세포를 취하여 생리식염수 미리리터당 106개가 되게 현탁하여 생쥐 1마리당 105개의 세포를 복강내 투여하고 1일이 경과한 후부터 9일간 매일 약물을 복강내 투여하고 60일간 관찰하였다. 대조구(생리 식염수 투여)의 마우스 생존 일수와 비교하여 산정한 마우스의 연명율(T/C, 퍼센트)을 구했다. 비교를 하기 위하여 사용한 공지의 아드리아마이신 염산염과 다우노루비신 염산염등 안트라사이클린계 항암약물, 그리고 신규 화합물들은 생리식염수에 용해하여 사용하여 동일하게 실험했다. 그 결과는 약물을 처리한 동물의 중간생존시간대 생리식염수를 처리한 동물의 중간 생존시간에 100을 곱한 비율로서 T/C퍼센트를 제 1표에 표시하였다.L1210 mouse plural sarcoma cells were taken from the abdominal cavity of CDF mice transplanted with L1210 plural sarcoma cells, suspended at 10 6 per ml of saline solution, and 10 5 cells per mouse were injected intraperitoneally for 9 days after 1 day. The drug was administered intraperitoneally daily and observed for 60 days. The survival rate (T / C, percent) of the calculated mice was compared with the number of days of survival of mice in the control group (physiological saline administration). Anthracycline anticancer drugs such as known adriamycin hydrochloride and daunorubicin hydrochloride, and novel compounds used for comparison were tested in the same manner by dissolving in physiological saline. The results are shown in Table 1 as T / C percent as the ratio of the median survival time of the drug-treated animals to the median survival time of the saline-treated animals multiplied by 100.

2) 적출심장의 심기능 측정2) Measurement of cardiac function of the extracted heart

실험동물을 각군 10마리씩 나누고 각 실험쥐에 30 mg/kg 용량으로 펀토바비탈 나트륨(sodium pentobarbital)을 복강주사하여 마취시킨 후 인공호흡 상태에서 흉부를 절개한다. 대동맥을 절개하고 삽입관을 삽입한 다음 폐장을 포함한 주위조직을 제거하고 곧이어 랑겐도르푸(Langendorff) 관류장치에 대동맥 삽입관을 연결시켜 역방향 관류를 하다. 관류액은 95% O2-5% CO2(Normoxic Condition)로 포화시킨 크렙스-한스라이트(Krebs-Henseleit, KH)완충용액 (염화나트륨 118 mM, 중탄산나트륨 27.2 mM, 염화칼륨 4.8 mM, 황산마그네슘 1.2mM, 중수소인산칼륨 1 mM, 염화칼슘 1.25 mM, 글루코스 10 mM, pH 7.4 )을 80 Cm 물의 일정 압력으로 관류하고, 심장 온도를 37oC로 일정하게 유지한다. KH용액으로 15분 동안 관류하여 심기능이 안정화되면 대동맥 삽입관에 장치된 3-방향 코크를 통해 안트라사이클린계 항암약물(20ug/KH용액 ml)을 1시간 동안 투여한다.Each animal was divided into 10 groups, and anesthetized by intraperitoneal injection of pentobarbital with sodium pentobarbital at a dose of 30 mg / kg. The aorta is dissected, the insertion tube is inserted, the surrounding tissue, including the lung, is removed, and the aortic insertion tube is connected to the Langendorff perfusion device for reverse perfusion. The perfusion solution was buffered with Krebs-Henseleit (KH) saturated with 95% O 2 -5% CO 2 (Normoxic Condition) (sodium chloride 118 mM, sodium bicarbonate 27.2 mM, potassium chloride 4.8 mM, 1.2 mM magnesium sulfate). , Potassium deuterium phosphate 1 mM, calcium chloride 1.25 mM, glucose 10 mM, pH 7.4) is perfused at a constant pressure of 80 Cm water and the heart temperature is kept constant at 37 ° C. When the cardiac function is stabilized by perfusion for 15 minutes with KH solution, anthracycline anticancer drug (20ug / ml of KH solution) is administered for 1 hour through a 3-way cork installed in the aortic intubation tube.

심기능의 지표로서 심박수와 좌심실 압력을 측정한다. 좌심실 압력은 끝에 풍선이 붙은 20G의 플라스틱 삽입관을 승모판을 통해서 좌심실에 삽입하고 압력변환기(Stathan P23XL)에 연결한 후, 생리기록계를 이용해서 측정한다. 이때 안정화된 심장의 좌심실 이완기말 압력(left ventricular end-diastolic pressure, LVEDP)이 2 mmHg가 되도록 풍선을 팽창시킨다. 심박수는 1분간 기록된 수축 횟수로 알 수 있으며 좌심실 압력 중 이완기말 압력은 심근의 수축(contracture) 정도를, 수축기말 압력과 이완기말 압력의 차이(developed pressure)는 심장의 수축력을 나타내는 지표로 사용한다. 심장의 혈액순환 능력(심기능 지수)은 수축기말 압력과 이완기말 압력의 차이에 심박수를 곱하여 산출하여 평가한다.Heart rate and left ventricular pressure are measured as indicators of cardiac function. Left ventricular pressure is measured using a physiological recorder by inserting a 20G plastic insertion tube with a balloon at the end through the mitral valve and connecting it to a pressure transducer (Stathan P23XL). The balloon is inflated so that the left ventricular end-diastolic pressure (LVEDP) of the stabilized heart is 2 mmHg. The heart rate can be measured by the number of contractions recorded for 1 minute, and the diastolic pressure in the left ventricular pressure is used as the index of the myocardial contracture, and the difference between the systolic pressure and the diastolic pressure (developed pressure) is used as an indicator of the contractile force of the heart. do. The heart's blood circulation capacity (cardiac function index) is calculated by multiplying the difference between the systolic and diastolic pressures by the heart rate.
