  • the conjugated drug can be maintained for tens, hundreds of hours or even longer, which is beneficial to the "enhanced penetration and retention" effect (ie, EPR effect) due to leakage of tumor capillaries; the drug is attenuated due to the increase in hydrodynamic volume
  • EPR effect enhanced penetration and retention
  • the renal elimination of the drug can protect the drug from being degraded by enzymes, prolong the half-life of the drug in the plasma, and increase the bioavailability of the drug.
  • anticancer drugs are highly enriched in cancerous organs, tissues or cells, which greatly reduces the toxic and side effects caused by the full body of small molecule anticancer drugs; It is limited to the endocytosis pathway, which is conducive to the delivery of drugs to the lysosome, thereby avoiding the drug resistance caused by the pumping of p-glycoprotein; stimulating or restoring immune function is conducive to killing cancer cells.
  • Polyethylene glycol is the most successful carrier in the field of polymer conjugated drug nanomedicine, and is called the "gold standard" carrier. In the past 30 years, great achievements have been made in PEGylated drug technology.

  • small molecules such as folic acid and RGD short peptides to create actively targeted polymer conjugated drugs is a popular strategy for targeting drugs to tumor cells.
  • Small molecule targeting accessories have the advantages of low immunogenicity, good storage stability, small size, easy modification, easy coupling with polymer carriers, good compatibility with various organic solvents and water solvents, and low cost. for antibodies and other ligands.
  • Folic acid is currently the most widely studied small molecule targeting ligand. It is a vitamin that can specifically bind to folate receptors on the cell surface. Folate receptors cannot enter healthy cells in the circulation, but are in the ovary. It is overexpressed in various cancer cells such as cancer, lung cancer, breast cancer, kidney cancer, endometrial cancer and colon cancer.
  • As an active targeting ligand folic acid has the unique advantage that it has a high binding affinity (K d ⁇ 10 -10 M) to the folate receptor. Due to its small size and simple structure, the interference with pharmacokinetics is negligible.
  • the active carboxyl groups in the structure of folic acid are highly reactive and can be easily coupled to polymer carriers containing hydroxyl or amino groups without impairing the intrinsic activity of folic acid.
  • Certain short peptides can specifically target cancer cells or tumor vascular endothelial cells, and some of these peptides are called cell-targeting peptides, which show a high degree of specificity and affinity for the corresponding target cells through interaction with receptors .
  • Cell-targeting peptides have been used in various therapeutic trials, of which the most extensively studied sequence is arginine-glycine-aspartic acid (RGD), the first homing peptide discovered.

Description

聚乙二醇偶联药物、其制备方法及用途 技术领域
本发明属医药技术领域,具体涉及聚乙二醇偶联药物、其制备方法及用途。
背景技术
高分子偶联药物可以大幅度增加药物分子的水溶性;可以防止或减少药物产生结块、免疫原性和抗原性;大多数的小分子药物在血液循环中只能保持数分钟,而高分子偶联药物可以保持几十、几百小时甚至更长,这有利于因肿瘤毛细血管的渗漏而产生的“增强渗透和保留”效应(即EPR效应);由于流体力学体积增加而减弱了药物的肾消除,保护药物不被酶降解,延长药物在血浆内的半衰期,增加药物的生物利用度。此外,通过主动靶向或EPR被动靶向使抗癌药高度富集在癌变的器官、组织或细胞,大幅度地降低因为小分子抗癌药充满全身而导致的毒副作用;将药物的细胞吸收局限于内吞路径,有利于向溶酶体方向的药物传输,从而避开p-糖蛋白泵出而导致的抗药性;刺激或恢复免疫功能,利于杀灭癌细胞。聚乙二醇是高分子偶联药物纳米医学领域最成功的载体,被称之为“黄金标准”载体。过去30年来,聚乙二醇化药物技术取得了巨大的成就,已经有17个聚乙二醇化药物被美国FDA批准进入市场销售,有1个聚乙二醇化药物被中国NMPA批准上市,此外还有近40个临床新药在进行一期、二期、三期临床试验和进入NDA阶段,其中半数为聚乙二醇化小分子药物。
利用如叶酸、RGD短肽等小分子创造主动靶向的高分子偶联药物是目前流行的将药物靶向肿瘤细胞的策略。小分子靶向配件由于具有免疫原性低、贮存稳定性好、体积小、易于修饰、易于与高分子载体偶联、与各种有机溶剂和水溶剂相容性好、成本低等优点,优于抗体及其他配体。
叶酸(FA)是目前研究最广泛的小分子靶向配体,它是一种维生素,能特异性地与细胞表面的叶酸受体结合,叶酸受体在循环中不能进入健康细胞,但在卵巢癌、肺癌、乳腺癌、肾癌、子宫内膜癌和结肠癌等多种癌细胞中过表达。作为一种活性靶向配体,叶酸具有独特的优势,它与叶酸受体有很高的结合亲和力(K d~10 -10M)。由于其体积小、结构简单,对药物动力学的干扰可以忽略不计。此外,叶酸结构中的活性羧基具有高度的反应性,很容易与含有羟基或氨基的聚合物载体偶联,而这种偶联不会损害叶酸的内在活性。
某些短肽能够特异性地靶向癌细胞或肿瘤血管内皮细胞,其中一些肽被称为细胞靶向肽,通过与受体的相互作用,对相应的靶细胞表现出高度的特异性和亲和力。细胞靶向肽已经被用于各种治疗试验,其中研究最广泛的序列是精氨酸-甘氨酸-天冬氨酸(RGD),这是第一个发现的归巢肽。RGD可以与肿瘤细胞和血管内皮细胞中上调的整合蛋白结合,RGD介导的药物传递系统能够提高化疗中靶向传递的效率。最近开发出来的内化RGD多肽(iRGD,CRGDK/RGPD/EC),是一种肿瘤靶向和细胞穿透的环肽,可通过依赖于神经肽-1的、肿瘤特异的方式增加结合物进入血管外肿瘤组织。与传统的环肽相比,iRGD调节的高分子偶联药物可以通过增强药物在肿瘤部位的富集和穿透性来显著提高肿瘤治疗的效果。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此,本发明提供了一种聚乙二醇偶联药物,其具有优异的肿瘤抑制活性。另外,发明人运用独特的化学合成方法,将小分子靶向配体如叶酸和iRGD多肽与抗癌药同时接枝在同一聚乙二醇高分子载体上,以提高聚乙二醇偶联药物的疗效。通过本发明的制备方法,可以高效、方便地制备本发明的聚乙二醇偶联药物。
为此,在本发明的第一方面,本发明提供了式(A)所示的聚乙二醇偶联药物或其药 学上可接受的盐,

实施例2聚乙二醇偶联药物对人乳腺癌MDA-MB-231细胞BALB/c裸鼠皮下移植瘤模型的药效试验
1、配制方法
供试品:
1)量取适量的本发明合成的作为对照的聚乙二醇偶联药物如49-166,加入适量的生理盐水,配制成合适浓度的溶液。
2)量取适量的待测聚乙二醇偶联药物如47-122,加入适量的生理盐水,配制成合适浓度的溶液。
阴性对照:直接使用生理盐水。
配制好的供试品和对照品给药前于2~8℃或冰盒保存,给药剩余的供试品和对照品按医疗垃圾处理。
2、细胞及实验动物
人乳腺癌细胞MDA-MB-231:来源于中国医学科学院基础所细胞资源中心,培养条件为RPMI1640+10%FBS,37℃、5%CO 2培养。
动物种属&品系:BALB/C裸鼠
动物等级:SPF级
实验动物来源:北京维通利华实验动物技术有限公司
肿瘤接种时周龄:约4-5周。
肿瘤接种时体重:约15~18g。同性别动物的体重在平均体重的80%~120%之间。
性别与数量:雌性,订购96只小鼠,筛选成模动物48只用于最终实验,剩余动物转交兽医或安乐死。
动物饲养于独立通风系统(IVC)中,每笼最多饲养同组6只动物,SPF级动物房,环境条件控制在室温20~26℃,相对湿度40%~70%,光照12小时明暗交替。在检疫驯养期间和试验期间,每天提供合格的鼠料(生产单位:北京科澳协力饲料有限公司),动物均自由摄食并自由饮水。
3、模型的建立
复苏MDA-MB-231细胞,进行细胞传代扩增,待扩增至足量细胞数时,收集处于对数生长期的细胞,准备进行细胞接种。
根据实际细胞数,调整细胞浓度在1×10 8个/mL,与基质胶(Matrigel Basement Membrance Matrix,BD公司)按1:1体积混合,得到浓度为5×10 7个/mL的细胞悬液,以0.2mL/只接种于96只小鼠右侧腋窝皮下。在接种后观察肿瘤生长情况,最终筛选得到肿瘤体积为77.30~292.27mm 3的48只成瘤动物用于试验。
4、动物分组和给药剂量
根据瘤体积和体重随机分为7组,其中,1组(阴性对照组,生理盐水)、6组(49-166,48mg/kg)、7组(47-122,51mg/kg),每组6只。静脉注射,各组在D1、D4、D7、D10、D13、D18、D21、D24给药,D27动物实施安乐死。
5、实验结果
5.1一般临床观察
观察频率及时间:实验期间,所有动物每天进行两次大体观察。
观察内容:包括动物精神状态、行为活动、摄食情况等。
5.2体重
检测动物:所有动物
检测时间:接收后、接种前、分组(即首次给药前)(D1)、以后每周2次、安乐死前称取动物体重。动物发生意外死亡或濒死安乐死时也称重。
5.3瘤径的测量
检测动物:所有动物
检测时间:分组(即首次给药当天为D1)、首次给药后每周2次、安乐死前,游标卡尺测量并记录肿瘤长、短径,计算肿瘤体积。
按照以下公式计算肿瘤体积:
V=1/2×长径×短径 2
试验期间每天2次观察动物一般临床症状,共进行10次体重和瘤径测量,安乐死后剥取肿瘤,称量肿瘤重量。计算瘤体积、相对肿瘤体积RTV、相对肿瘤增殖率T/C%、瘤重抑制率IR TW%。
6、结果分析与评价
统计分析:本试验使用统计学软件SPSS13.0对数据进行处理,计量资料以平均值±标准误来表示。具体分析过程如下:
用单因素方差分析(ANOVA)进行统计分析,如果ANOVA有统计学意义(P≤0.05)且方差齐性,用Tukey test进行组间比较分析,若方差不齐性,则用Dunnett’s T3test进行组间比较分析。
6.1根据肿瘤体积进行疗效评价
按照以下公式计算相对肿瘤体积(RTV)和相对肿瘤增殖率T/C%:
RTV=V t/V 0
V t:每天测量肿瘤得到的瘤体积
V 0:初始瘤体积(给药前)
T/C%=给药组的RTV平均值/对照组的RTV平均值×100%
以给药组相对肿瘤增殖率T/C%≤40%且该组RTV与阴性对照组RTV相比P≤0.05为有效,有肿瘤增长抑制作用;反之,如果T/C%>40%,则为对肿瘤增长无抑制作用。
6.2根据肿瘤重量进行疗效评价
实验结束后,剥离肿瘤结节并进行称重,比较各组间肿瘤重量的差异以进一步计算肿瘤抑制率IR TW,以IR TW≥60%为有效性辅助参考指标,计算公式如下:
IR TW(%)=(W 模型组-W 给药组)/W 模型组×100%
6.3大体解剖观察
对实验期间死亡动物以及观察期结束后安乐死动物进行大体解剖,对主要脏器进行观察,看是否有肉眼可见明显异常。
6.4照片记录
对安乐死动物及肿瘤进行照相。
具体结果如下:
整个试验过程中,各组动物未见明显异常。各组动物体重试验期间缓慢增长,各供试品组与第1组间未见显著性差异(P>0.05)。
阴性对照组(1组)整个试验中,肿瘤逐渐增长,至试验结束时(D27),1组平均瘤体积为2962.92±2176.59mm 3,平均RTV为19.14±12.01;6、7组的平均肿瘤体积分别为1690.27±785.04mm 3、1041.24±291.96mm 3,平均RTV分别为13.03±5.43、8.12±2.34。
各组肿瘤增长趋势见图1。
至实验结束时(D27),6、7组T/C%值分别为68.08%、42.41%,其IR TV%分别为31.92%、57.59%。
试验结束时,动物安乐死后称量瘤重,1、6、7组的平均瘤重分别为2.555±2.207g、 0.990±0.399g、0.544±0.127g。6、7组的IR TW%分别为61.24%、78.71%。
各组肿瘤重量抑制率示意图见图2。
结论:在本实验条件下,49-166在48mg/kg剂量下、47-122在51mg/kg剂量下,尾静脉注射给药对人乳腺癌MDA-MB-231细胞BALB/c裸鼠皮下移植瘤的生长均有明显的抑制作用,但47-122抑瘤作用显著优于49-166。
发明人通过以上实验和结果发现,本发明的聚乙二醇偶联药物对皮下移植瘤(例如,人乳腺癌MDA-MB-231细胞BALB/c裸鼠皮下移植瘤)的抗肿瘤作用显著。
