Description

안트라사이클라인계 항암약물 봉입용 리포솜 및 이의 제조방법{Anthracycline anticancer drug-encapsulated liposomes and preparation method thereof}Anthracycline anticancer drug-encapsulated liposomes and preparation method

본 발명은 양전하를 갖는 지질과 인지질을 함유하는 리포솜에 폴리에틸렌글리콜(PEG) 유도체를 도입하여 이온성 리포솜을 제조함으로써 암세포 내로 효과적으로 이입되어 항암약물의 투여가 용이한 세포이입성이 증진된 안트라사이클라인계 항암약물 봉입용 리포솜 및 이의 제조방법에 관한 것이다. The present invention provides an anthracycline-based system that is easily introduced into cancer cells by introducing polyethylene glycol (PEG) derivatives into liposomes containing lipids and phospholipids with positive charges to prepare ionic liposomes, thereby facilitating administration of anticancer drugs. It relates to anti-cancer drug encapsulation liposomes and a method for preparing the same.

리포솜은 체내에 존재하는 인지질을 주성분으로서 사용하기 때문에 생체적합성이 우수하고 병소로의 효율적인 약물전달을 수행 할 수 있는 입자성 전달체로서 많이 응용되어 왔다[A.D. Bangham, M. Standish, J. C. Watkis, J. Mol. Biol., 13, 238(1965)]. 리포솜은 독성이 강한 항암 약물 등의 전달체로서 약물 고유의 독성과 이에 수반되는 심각한 부작용을 감소시키는 장점을 가지고 있다[D. Needham, M. W. Dewhirst, Adv. Drug Deliver. Rev., 53, 285(2001)]. 특히, 안트라사이클린 계열의 항암약물은 심장에 강한 독성을 나타내며, 심장 이외의 조직이나 장기에서도 정상세포에까지 영향을 미치는 심각한 부작용을 나타내는 특성 이 있다. 이러한 독성이 강한 항암약물을 효율적으로 암 조직까지 운반하기 위해 리포솜을 이용함으로써 약물의 독성을 감소시키고 체내 순환시간을 증가시킬 수 있다고 보고되었다[D.J.A. Crommelin, L. van Bloois, Int. J. Pharm., 17, 135(1983)]. 그러나, 이와 같은 리포솜의 장점에도 불구하고 체내 투여된 리포솜은 혈장 단백질의 흡착과 생체효소들에 의한 지질의 분해 등에 의해서 구조적인 불안정성이 보고되었다[Alberto Gabizon, Adv. Drug Deliver. Rev., 16, 285(1995)]. 따라서, 기존의 리포솜의 표면에 생체적합성 고분자 물질을 도입하여 혈장 단백질과의 흡착을 방지함으로써 혈액 내에서 리포솜의 안정성과 순환시간을 증가시키는 연구가 활발히 진행되고 있다[H. Takeuchi, H. Kojima, H. Yamamoto, Y. Kawashima, J. Control. Release, 75, 83(2001)].Since liposomes use phospholipids present in the body as main components, they have been widely applied as particulate carriers that are excellent in biocompatibility and capable of efficient drug delivery to lesions [A.D. Bangham, M. Standish, J. C. Watkis, J. Mol. Biol., 13, 238 (1965). Liposomes are highly toxic anticancer drugs and have the advantage of reducing the inherent toxicity of drugs and the serious side effects that accompany them [D. Needham, M. W. Dewhirst, Adv. Drug Deliver. Rev., 53, 285 (2001). In particular, anti-cancer drugs of the anthracycline series has a strong toxicity to the heart, and has a characteristic side effects that affect the normal cells in tissues and organs other than the heart. It has been reported that the use of liposomes to efficiently transport these highly toxic anticancer drugs to cancer tissues can reduce drug toxicity and increase body circulation time [D.J.A. Crommelin, L. van Bloois, Int. J. Pharm., 17, 135 (1983). However, despite the advantages of liposomes, the liposomes administered in the body have been reported structural instability due to the adsorption of plasma proteins and the degradation of lipids by bioenzymes [Alberto Gabizon, Adv. Drug Deliver. Rev., 16, 285 (1995). Therefore, studies are being actively conducted to increase the stability and circulation time of liposomes in the blood by introducing biocompatible polymer materials on the surface of existing liposomes to prevent adsorption with plasma proteins [H. Takeuchi, H. Kojima, H. Yamamoto, Y. Kawashima, J. Control. Release, 75, 83 (2001).

수용성 고분자인 PEG는 생체 내 독성이 없는 생체적합성 고분자로서 단백질, 혈소판 등의 혈액성분, 세포 및 조직과의 상호작용을 거의 하지 않는 특성을 나타내고 있어 PEG를 리포솜의 표면개질용 물질로서 이용하는 시도가 있다[M.C. Woodle, D.D. Lasoc, Biochem. Biophys. Acta, 1113, 2(1992), V.P. Torchilin, J. Micro encapsul. 15, 1(1998), C.R. O'Riordan, A. Lachapelle, C. Delfado, V. Parkes, S.C. Wadsuorth, A.E. Smith, G.E. Francis, Hum. Gene Ther., 10(1999)]. 이러한 PEG를 리포솜에 도입시킨 리포솜을 제조하는 방법으로서 PEG를 지질에 공유결합시킨 1,2-디스테로일-sn-글리세로-3-포스포에탄올아민-N-[메톡시-(폴리에틸렌글리콜)-2000](DSPE-mPEG-2000)을 리포솜을 구성하는 성분으로 사용하여 혈류 내의 단백질 흡착과 세망내피계(reticuloendothelial system)로부터 안정한 리포솜 을 제조하는 것에 관한 연구가 보고되었다[Boris Ceh, Mathias Winterhalter, Peter M. Frederik, Joseph J. Vallner, Danilo D. Lasic, Adv. Drug Delivery Reviews, 24(1997)]. 이러한 PEG 도입 리포솜은 세망내피계에 의한 리포솜의 혈류 내 손실을 감소시키고 향상된 투과성과 체류(Enhanced permeability and retention, EPR) 효과에 의해서 종양조직으로의 리포솜의 전달 효율을 증가시키지만 종양세포 주위로 전달된 리포솜을 세포 내로 이입시키는 데에는 기술적 한계가 있었다[Alberto Gabizon, Hilary Shmeeda, Aviva T. Horowitz, Sammuel Zalipsky, Adv. Drug Deliver. Rev., 56, 1177(2004)]. 미국 특허 제5,013,556호는 인지질에 공유 결합시킨 PEG를 사용하여 리포솜을 제조함으로써 리포솜의 체내 순환시간을 증가시키는 방법을 개시하였다. 그러나, 상기 특허에서 PEG가 도입된 리포솜은 혈액 내에서 안정하지만, 리포솜을 세포 내로 효과적으로 이입시키는 데에는 한계가 있었다.As a water-soluble polymer, PEG is a biocompatible polymer that has no toxicity in vivo. It shows a characteristic that little interaction with blood components such as proteins and platelets, cells, and tissues has been attempted to use PEG as a material for surface modification of liposomes. MC Woodle, DD Lasoc, Biochem. Biophys. Acta, 1113, 2 (1992), VP Torchilin, J. Micro encapsul. 15, 1 (1998), CR O'Riordan, A. Lachapelle, C. Delfado, V. Parkes, SC Wadsuorth, AE Smith, GE Francis, Hum. Gene Ther., 10 (1999). As a method for preparing a liposome in which such PEG is introduced into liposomes, 1,2-desteroyl-sn-glycero-3-phosphoethanolamine-N- [methoxy- (polyethylene glycol) in which PEG is covalently bonded to lipids -2000] (DSPE-mPEG-2000) as a constituent of liposomes has been reported to produce protein liposomes in the bloodstream and to produce stable liposomes from the reticuloendothelial system [Boris Ceh, Mathias Winterhalter, Peter M. Frederik, Joseph J. Vallner, Danilo D. Lasic, Adv. Drug Delivery Reviews, 24 (1997). These PEG-induced liposomes reduce liposome loss in the bloodstream by the reticuloendothelial system and enhance the delivery efficiency of liposomes to tumor tissues by enhanced permeability and retention (EPR) effects but are delivered around tumor cells. There were technical limitations to the incorporation of liposomes into cells [Alberto Gabizon, Hilary Shmeeda, Aviva T. Horowitz, Sammuel Zalipsky, Adv. Drug Deliver. Rev. , 56, 1177 (2004). US Pat. No. 5,013,556 discloses a method for increasing the circulating time of liposomes by preparing liposomes using PEG covalently bound to phospholipids. However, although the liposomes to which PEG is introduced in the patent are stable in blood, there are limitations in effectively introducing liposomes into cells.

미국 특허 제7,135,192호는 양이온성 지질을 이용한 리포솜을 제조하여 리포솜의 세포 내 이입을 증가시켰다. 그러나 상기의 특허는 PEG가 도입되지 않은 양이온성 리포솜으로서 리포솜의 체내 순환시간을 증가시키는데 한계가 있었다.US Pat. No. 7,135,192 prepared liposomes using cationic lipids to increase the cellular uptake of liposomes. However, this patent is limited to increasing the circulation time of liposomes as cationic liposomes without PEG.

따라서, 본 발명은 리포솜의 세포 내 이입을 증가시킬 수 있는 리포솜의 제조로서 그 표면에 PEG가 도입된 이온성 리포솜을 제조함으로써 종양 조직으로 전달 된 리포솜이 암세포 내로 효과적으로 흡수될 수 있는 리포솜을 개발하였다. Accordingly, the present invention has developed liposomes that can effectively absorb liposomes delivered to tumor tissues by preparing ionic liposomes with PEG introduced thereon as liposomes capable of increasing intracellular import of liposomes into cancer cells. .

이에, 본 발명자들은 암 세포로의 이입이 효과적으로 증가될 수 있는 이온성 리포솜을 개발하기 위하여 연구한 결과, 리포솜의 세포 내 이입을 증가시킬 수 있는 리포솜의 제조로서 양전하를 갖는 지질과 인지질을 함유하는 리포솜 표면에 PEG를 도입시켜 이온성 리포솜을 제조하였고, 제조된 리포솜이 암세포 내로의 이입이 증가되는 것을 확인하게 되어 본 발명을 완성하게 되었다. Therefore, the present inventors have studied to develop an ionic liposome that can effectively increase the import into cancer cells, and as a result of the preparation of liposomes that can increase the intracellular import of liposomes containing lipids and phospholipids with a positive charge Ionic liposomes were prepared by introducing PEG into the liposome surface, and it was confirmed that the imported liposomes were increased into cancer cells to complete the present invention.

따라서, 본 발명은 리포솜의 표면에 PEG를 가지고 있으면서 세포 내 이입성이 증진된 이온성 리포솜 및 이의 제조방법을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide an ionic liposome having a PEG on the surface of the liposome and enhanced incorporation into cells, and a method for preparing the same.

상기 과제를 해결하기 위하여 본 발명은 양전하를 갖는 지질과 인지질을 함유하는 리포솜에 폴리에틸렌글리콜(PEG) 유도체를 도입한 안트라사이클라인계 항암약물 봉입용 리포솜 및 이의 제조방법을 그 특징으로 한다.In order to solve the above problems, the present invention is characterized by an anthracycline-based anticancer drug-encapsulated liposome incorporating a polyethylene glycol (PEG) derivative into liposomes containing lipids and phospholipids with a positive charge, and a method of preparing the same.

이상에서 상술한 바와 같이, 본 발명은 폴리에틸렌글리콜(PEG)을 그 표면에 갖는 이온성 리포솜의 제조방법에 관한 것으로, 양전하를 갖는 지질과 인지질에 공유 결합된 PEG 유도체를 혼합하여 리포솜을 제조하는 방법, 말단에 음전하를 갖는 PEG 유도체와 양전하를 갖는 지질과의 이온결합에 의한 복합체를 제조한 후 이를 사용하여 리포솜을 제조하는 방법, 그 표면이 양전하를 갖는 리포솜에 음전하를 갖는 PEG 유도체를 이온결합시킴으로써 리포솜의 표면에 PEG가 도입된 리포솜을 제조하는 방법 그리고 양전하를 갖는 인지질과 폴리에틸렌 옥사이드-폴리프로필렌 옥사이드-폴리에틸렌 옥사이드 공중합체(PEO-PPO-PEO:pluronic)를 구성성분으로 하여 그 표면에 PEG가 도입된 리포솜을 제조하는 방법을 통해 제조된 이온성 리포솜은 종래의 리포솜에 비해 우수한 암세포 이입율을 나타낸다. As described above, the present invention relates to a method for producing an ionic liposome having polyethylene glycol (PEG) on its surface, and a method for producing a liposome by mixing a lipid having a positive charge and a PEG derivative covalently bonded to a phospholipid. , A method for preparing a liposome using an ion bond between a PEG derivative having a negative charge at the end and a lipid having a positive charge, and then using the same to prepare a liposome, by ionically bonding a PEG derivative having a negative charge to a liposome having a positive charge on its surface Method for preparing liposomes incorporating PEG on the surface of liposomes and PEG on the surface of the positively charged phospholipids and polyethylene oxide-polypropylene oxide-polyethylene oxide copolymers (PEO-PPO-PEO: pluronic) The ionic liposomes prepared by the method of preparing the liposomes prepared are superior to the conventional liposomes. Cancer cell migration rate is shown.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명은 양전하를 갖는 지질과 인지질을 함유하는 리포솜에 폴리에틸렌글리콜(PEG) 유도체를 도입하여 이온성 리포솜을 제조함으로써 암세포 내로 효과적으로 이입되어 항암약물의 투여가 용이한 세포이입성이 증진된 안트라사이클라인계 항암약물 봉입용 이온성 리포솜 및 이의 제조방법에 관한 것이다. The present invention provides an anthracycline-based system that is easily introduced into cancer cells by introducing polyethylene glycol (PEG) derivatives into liposomes containing lipids and phospholipids with positive charges to prepare ionic liposomes, thereby facilitating administration of anticancer drugs. The present invention relates to an ionic liposome for anticancer drug encapsulation and a method for preparing the same.

본 발명은 양전하를 갖는 지질과 인지질을 함유하는 리포솜에 폴리에틸렌글리콜(PEG) 유도체를 도입하여 이온성 리포솜에 관한 것으로서, 상기 리포솜을 제조하기 위하여 양전하를 갖는 지질, 인지질, 스테롤류, PEG 유도체가 혼합 사용되어 진다.The present invention relates to ionic liposomes by introducing polyethylene glycol (PEG) derivatives into liposomes containing lipids and phospholipids with a positive charge, wherein a positive charge lipid, phospholipids, sterols, and PEG derivatives are mixed to prepare the liposomes. It is used.

상기 양전하를 갖는 지질로는 1,2-디스테로일-3-트리메틸암모늄-프로판(DSTAP), 디메틸디옥타데실암모늄(DDAB), 1,2-디아실-3-디메틸암모늄-프로판(DAP), La-디올레일 포스파티딜에탄올아민(DOPE) 등을 들 수 있다. 양전하를 갖는 지질은 리포솜 형성 지질 중에서 1.0 ~ 25 몰% 포함하는 것이 바람직하다. 양전하를 갖는 지질의 비율이 상기 범위를 벗어나는 경우에는 리포솜의 제조 및 리포솜의 이온성과 입자크기에 문제가 있다.The positively charged lipids include 1,2-disteroyl-3-trimethylammonium-propane (DSTAP), dimethyldioctadecylammonium (DDAB), 1,2-diacyl-3-dimethylammonium-propane (DAP) And La-dioleyl phosphatidylethanolamine (DOPE). The lipid having a positive charge is preferably included in 1.0 to 25 mol% of liposome-forming lipids. If the proportion of lipids having a positive charge is out of the above range, there is a problem in the preparation of liposomes and the ionicity and particle size of liposomes.

또한, 상기 리포솜의 성분인 인지질로는, 예를 들어 포스파티딜콜린으로서 대두 포스파티딜콜린, 난황 포스파티딜콜린, 보바인 포스파티딜콜린, 디라우로일포스파티딜콜린, 디미리스토일포스파티딜콜린, 디팔미토일포스파티딜콜린 또는 디스테아로일포스파티딜콜린 등, 포스파티딜에탄올아민으로서 디라우로일포스파티딜에탄올아민, 디미리스토일포스파티딜에탄올아민, 디팔미토일포스파티딜에탄올아민 또는 디스테아로일포스파티딜에탄올아민, 디오레오일포스파티딜에탄올아민 등, 포스파티딜세린으로서 디라우로일포스파티딜세린, 디미리스토일포스파티딜세린, 디팔미토일포스파티딜세린 또는 디스테아로일포스파티딜세린 등, 포스파티딘산, 포스파티딜글리세롤로서 디라우로일포스파티딜글리세롤, 디미리스토일포스파티딜글리세롤, 디팔미토일포스파티딜글리세롤 또는 디스테아로일포스파티딜글리세롤 등, 포스파티딜이노시톨로서 디라우로일포스파티딜이노시톨, 디미리스토일포스파티딜이노시톨, 디팔미토일포스파티딜이노시톨 또는 디스테아로일포스파티딜이노시톨 등, 리조포스파티딜콜린, 스핑고미엘린, 난황 레시틴, 대두 레시틴 또는 수소첨가 인지질 등의 천연 또는 합성 인지질 등을 들 수 있다. 상기 인지질은 리포솜 형성 지질 중에서 30 ~ 60 몰% 포함하는 것이 바람직하다. 인지질의 비율이 상기 범위를 벗어나는 경우에는 리포솜의 안정성이 저하되며 약물의 봉입에 문제가 있다. The phospholipids of the liposomes include, for example, soybean phosphatidylcholine, egg yolk phosphatidylcholine, bovine phosphatidylcholine, dilauroylphosphatidylcholine, dipyryltoylphosphatidylcholine, dispalalloylphosphatidylcholine, and the like as phosphatidylcholine. Dilauroyl as phosphatidylserine, such as dilauroyl phosphatidyl ethanolamine, dimyristoyl phosphatidyl ethanolamine, dipalmitoyl phosphatidyl ethanolamine or distearoyl phosphatidyl ethanolamine, and diopatiyl phosphatidyl ethanolamine as phosphatidyl ethanolamine Phosphatidylserine, dimyristoyl phosphatidylglycerol, dimyristoyl phosphatidylglycerol, diphosphoilyl phosphatidylglycerol, as phosphatidine acid, phosphatidylglycerol, and the like Dilauroyl phosphatidylinositol, dimyristoyl phosphatidyl inositol, dipalmitoyl phosphatidylinositol or distearoyl phosphatidyl inositol, such as palmitoyl phosphatidylglycerol or distearoyl phosphatidyl glycerol, and risphosphosphidyl myoline Natural or synthetic phospholipids such as egg yolk lecithin, soybean lecithin or hydrogenated phospholipids. It is preferable that the phospholipid contains 30 to 60 mol% in liposome-forming lipids. If the ratio of phospholipid is out of the above range, the stability of the liposome is lowered and there is a problem in the encapsulation of the drug.
