Description

A kind of polyglycerol fatty acid ester derivative of hydroxycamptothecine
Technical field
Key in herein technical field and describe paragraph.The present invention relates to pharmaceutical field, particularly relate to polyglycerol fatty acid ester derivative of a kind of hydroxycamptothecine and preparation method thereof, with and in the purposes of preparing aspect antitumor drug.
Background technology
Camptothecine (Camptothecin, CPT), its structure, as shown in formula I, is separated and obtains from Chinese endemic plant camplotheca acuminata by American scientist Wall the earliest, is a kind of poisonous alkaloids.Camptothecine has excellent anti-tumor activity, but also has very large toxic side effect.The outstanding representation of camptothecine antitumous effect, causes the interest that people are very large, and analogue naturally occurring to it or synthetic is studied in succession, to find new antitumor drug.At this wherein, hydroxycamptothecine (Hydroxycamptothecin, HCPT) compared with camptothecine, have advantages of that anticancer therapeutic is higher, toxic side effect still less, in the treatment of cancer of the stomach, liver cancer, leukemia, mammary cancer, tumor of head and neck, there is very strong using value, in China is clinical, be widely used; The derivative of hydroxycamptothecine, water-soluble prodrug (the Iriontecan of SN-38 (SN-38), irinotecan), Topotecan (Topotecan, Top is for health) also respectively at 1994 and listing in 1999, for the treatment of colorectal cancer, ovarian cancer and small cell lung cancer.In addition, also have a large amount of camptothecin analogues or derivative still among research and development, as Chinese patent literature I (Granted publication CN100432076/C) has been introduced the camptothecin derivative that contains dihydrofuran ring, Chinese patent literature II (application publication number CN102574866A) has been introduced 14-nitro, 14-amino and 14-substituted-amino camptothecin derivative, and Chinese patent literature III (application publication number CN102731772A) has been introduced the polyethyleneglycol derivative of camptothecine compounds.
Figure 2014100037472100002DEST_PATH_IMAGE002
The chemical structure of formula (I) camptothecine
Research shows, the anti-tumor activity of camptothecine and analogue thereof is mainly that the activity of the topoisomerase I (Topo I) by inhibition tumor cell plays a role.In the reproduction process of fissional DNA, Topo I and DNA, in conjunction with forming a binary complex, and make DNA in reproduction process, have a temporary transient strand breach, and its semiconservative replication can be carried out smoothly.If give camptothecine or derivatives thereof in this process, it can be at fissional S phase and Topo I-DNA mixture specific binding, form an irreversible Topo I-CPT-DNA ternary complex, make the termination that copies of DNA, thereby produce the lethal effect to cell.
Camptothecine and analogue thereof the unique restraining effect to topoisomerase I, closely related with the lactone structure that its E ring exists.Because there are some researches show, only have camptothecine ability and the Topo I-DNA of lactone form to form stable mixture, this may be important step of its performance antitumous effect.And the camptothecine of lactone form and analogue thereof exist with carboxylic acid form because lactone unstable is easy to reversibility open loop, thereby in human plasma, exist the balance of two kinds of forms.Owing to only having sour environment to be just conducive to the existence of lactone form, and carboxylic acid form and plasma proteins bonding force higher, so camptothecine and analogue thereof enter after blood, the concentration of its lactone form will be well below the concentration of carboxylic acid form.More disadvantageously, the camptothecine of carboxylic acid form and analogue anti-tumor activity thereof strengthen compared with the obvious decline of lactone form and untoward reaction, and the camptothecine of lactone form is water-soluble hardly, and the unfavorable feature such as it is short to have biological half-life, and tissue bond is poor.Therefore, improve the water-soluble of camptothecin analogues, extend the residence time in its body, the stability that increases metabolism becomes the emphasis of this compounds and preparation research thereof.
Camptothecine compounds biological half-life is short, water-fast defect almost, and the formulation of listing does not solve well at present.As " hydroxycamptothecine sodium chloride injection " and " hydroxycamptothecin for injection " in Discussion on Chinese Listed, in order to solve its solubility in water, the reaction of utilization and alkali impels lactonic ring to open formation carboxylate salt.Improve although water-soluble, because the Concentration of Hydroxycamptothecinein of lactone form is too low, still existed anti-tumor activity and obviously reduce, the defect that toxic side effect increases.
For improving clinical efficacy, improve the many unfavorable feature of camptothecin analogues, people's research direction mainly concentrates on two aspects.First, the chemical structure of camptothecine is carried out to various transformations, as increase hydrophilic radical, use prodrug technology etc., there is in this respect a large amount of bibliographical information (Chinese patent literature I ~ III as the aforementioned) both at home and abroad, also obtained certain applicability achievement, if medicine irinotecan and Top are for the listing of health.But these applicability achievements still exist some insoluble problems, as not fully up to expectations distribution and action time in vivo in medicine, use inconvenience etc.In order to solve this class problem, people carry out effort in second aspect in succession, use some novel drug delivery systems (as nanoparticle, liposome, micro emulsion, micella etc.) to reaching desirable effect.These newtype drug delivery systems, change camptothecine and analogue thereof pharmacokinetic parameter and bio distribution characteristic in vivo, having residence time prolongation, useful for drug delivery amount in slowly-releasing, body increases texts, thereby can play raising curative effect, alleviates the object of toxic side effect.
In these newtype drug delivery systems, for strengthening the water-soluble of medicine, the extension body internal recycle time, utilize polyoxyethylene glycol (Polyethylene glycol, PEG) to transmit medicine or drug delivery system itself is modified, be a kind of very common selection.If first liposome medicament Zorubicin of U.S. FDA approval is to adopt polyethyleneglycol modified phosphatide prescription, (the non-patent literature I such as Hong Minghuang, Journal of Controlled Release, 2010, 141:22-29) by Transferrins,iron complexes, polyoxyethylene glycol combines with hydroxycamptothecine, to strengthen its water-soluble and targeting, reach good effect, the people's such as Liu Keliang Chinese patent (Chinese patent literature III) also provides the Preparation method and use of the PEGization derivative of camptothecine compounds, can be with reference to the people's such as Zhang Yue summary (non-patent literature II about utilizing polyoxyethylene glycol to modify more document to medicine, Hebei University of Science and Technology's journal, 2013, 34, 4:355-365).
But, also there is certain problem in medicine and drug delivery system that PEG modifies, after being the most significantly wherein the drug delivery system first administration of Pegylation, the medicine of subsequent dose shortens cycling time in blood, and assemble in a large number in liver and spleen, do not reach effective drug level and action time, this is called as " accelerate blood flow and remove phenomenon (accelerated blood clearance phenomenon, ABC) ".About " ABC phenomenon ", in many medicines or drug delivery system that utilize PEG modification, found by people very early, relevant report is also a lot, cause the IgM of anti-PEG and occur being eliminated fast phenomenon (non-patent literature III with regard to having introduced by polyethyleneglycol modified albumen in 1999 as Cheng TL, Bioconjugate Chemistry, 1999,10:520-528).For " the ABC phenomenon " that caused by PEG, its concrete origin cause of formation does not still have clear and definite conclusion, there is report (non-patent literature IV, Journal of Controlled Release, 2006,115:243-250) think that " ABC phenomenon " is the result of human body innate immune system effect, its mechanism may with PEG in
Figure 2014100037472100002DEST_PATH_IMAGE004
repeating unit is relevant, and the medicine of modifying as PEG or drug delivery system be while arriving for the first time immune organ spleen,
Figure 580334DEST_PATH_IMAGE004
immunoglobulin (Ig) on the active B cell of chain and splenic marginal zone and combining, B cell is produced to special stimulation, make it secrete the IgM of anti-PEG, thereby cause medicine or its transfer system to be assembled liver and spleen, blood Chinese traditional medicine concentration reduces and goes out " accelerate blood flow and remove phenomenon ", and shortened the action time of medicine.
Polyglycerine (Polyglycerol, PG) is important fine chemical product and synthetic intermediate, is just in the news, but because of product quality problem, is restricted in the application of the aspects such as food, medicine and daily use chemicals as far back as its study on the synthesis of 20 beginnings of the century.In recent years, along with further investigation and the improvement of people to Polyglycerine, its quality improves greatly, at present, more existing major companies (as the Su Wei chemical of Belgian Su Wei group, Japanese Ban Ben pharmaceutical industries Co., Ltd., Italian SPIGA company and the Jinan Dong Run Science and Technology Ltd. etc. that refines) provide commercial high-quality polyglycerol, can directly apply in makeup and pharmaceutical prod.
For fear of or alleviate " the ABC phenomenon " of medicine or drug delivery system, people have carried out many other good tries.Wherein there is document (non-patent literature V, International Journal of Pharmaceutics, 2013, the phosphatidylethanolamine (PG-DSPE) of 456:235-242) Polyglycerine being modified replaces the preparation of polyethyleneglycol modified phosphatidylethanolamine (PEG-DSPE) for Evacet, has effectively avoided " ABC phenomenon ".Its mechanism may be the lipid of modifying with branched polyglycerol,
Figure 2014100037472100002DEST_PATH_IMAGE006
in repeating unit-CH 2the existence of OH side chain forms sterically hindered, interaction and (or) the effectively combination of B cell immunoglobulin and repeating unit are hindered, make B cell lack effective specific stimulation, cannot secrete or secrete the IgM of few anti-PG, thereby eliminate or minimizing " ABC phenomenon ".But this research is only confined to form the phospholipid material of liposome, can produces which kind of effect to medicine itself with Polyglycerine modification and mention.
Therefore, not good, a kind of non-polyethyleneglycol modified new medicaments derivative of shortcoming exploitation such as action time is short, toxic side effect is strong that distributes in, body low for solubleness in camptothecine compounds water, seems and is more of practical significance.
?
