Definitions

  • the invention belongs to the technical field of medicine, and in particular relates to a polyethylene glycol-coupled drug and its application.
  • PEGylated drugs Compared with the original drug, PEGylated drugs have great advantages, such as increasing the water solubility of drug molecules; preventing or reducing drug agglomeration, immunogenicity and antigenicity; many drugs can only remain in the blood circulation for a few minutes , while polyethylene glycol-conjugated anticancer drugs can be kept for dozens, hundreds of hours or even longer, which is beneficial to the "enhanced penetration and retention" effect caused by the leakage of tumor capillaries, that is, the EPR effect; due to the fluid
  • the increase in mechanical volume weakens the renal elimination of drugs, protects drugs from enzymatic degradation, prolongs the half-life of drugs in plasma, and increases the bioavailability of drugs; through EPR passive targeting or active targeting, anticancer drugs are highly enriched in Cancerous organs, tissues or cells can greatly reduce the toxic and side effects caused by small molecule anticancer drugs filling the whole body; the cellular absorption of drugs is limited to the endocytic pathway, which is conduc

Description

聚乙二醇偶联药物及其用途 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及其用途。
背景技术
聚乙二醇化药物相对于原药有着巨大的优势,如可以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;很多药物在血液循环中只能保持数分钟,而聚乙二醇偶联抗癌药可以保持几十、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;通过EPR被动靶向或主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。
美国NEKTAR公司、ENZON公司等的聚乙二醇偶联药物技术取得了巨大的成功,迄今为止已经有26个药被美国FDA批准进入市场销售,韩国、俄罗斯、印度和中国的药监局也批准过聚乙二醇化药物进入市场销售。不过,以上所有的聚乙二醇化药物都是聚乙二醇化单药。
本申请发明人研发出了一些特别的尿素结构连接方法,可以将某些药物单独或与别的药物或增效剂同时接在聚乙二醇载体上,得到的聚乙二醇偶联药物具有显著的疗效。
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、其立体异构体或其药学上可接受的盐,其具有优异的肿瘤抑制活性或优异的眼科疾病(如脉络膜新生血管)治疗活性。
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、其立体异构体或其药学上可接受的盐,

小鼠麻醉后,在视网膜镜下用半导体激光于视乳头周围做视网膜光凝,照射部位位于距视乳头一个视盘直径以外血管之间,以光凝后有气泡产生为击破Bruch膜的标志。#6和#7小鼠的激光造模条件为350mw和200ms,而#5小鼠的激光造模条件为300mw和260ms,光凝时间1s,光凝之后一周开始用药进行治疗,给药方法为将前述制备的20mg/mL的化合物39-205的溶液和阿帕西普的生理盐水溶液分别用玻璃体腔注射1μL溶液。
实验结果:实验结果如图1-图4所示。从图1可以看出,5号光斑未见明显减小,眼底造影无明显改善。从图2-图4可以看出,6、7号小鼠造模成功,视网膜血管扩张,散在激光斑,激光斑内有盘状荧光渗漏,给药后可减小光斑面积。

4实验设计
4.1模型的建立
复苏BT474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。
细胞接种前将雌激素缓释片(17β-ESTRADIOL,货号:SE-121,Innovative Research of America)埋植于NPG小鼠颈背部皮下。将浓度为5×10 7~1×10 8个/mL的BT474细胞悬液与基质胶(Matrigel Basement Membrance Matrix,BD公司)按1:1体积混合,得到浓度为2.5×10 7~5×10 7个/mL的细胞悬液,取0.2mL接种于小鼠右侧乳房垫内。在接种后观察肿瘤生长情况,待肿瘤体积约为100~300mm 3时,按瘤体积大小进行筛选,瘤体积过大及未成瘤者不予入选,最终筛选得到36只成瘤动物用于试验。
4.2动物分组和给药剂量
筛选合格的成模动物48只,依据瘤体积大小随机分为8组,每组6只。
4.3给药
给药途径:阴性对照、阳性对照、48-124、39-205、61-104、51-151静脉注射。
给药频率和时间:每4天给药1次,连续4~5周;
给药容量:根据每只动物给药前体重,确定每只动物的给药量;
给药途径的选择理由:与临床拟用给药途径一致。
4.4一般临床观察
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。
4.5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。
4.6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
4.7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%
如果T/C%≤40%,且实验组RTV与模型组RTV经统计学处理P<0.05,为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。
4.8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%
4.9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。
4.10照片记录
对安乐死动物及肿瘤进行照相。
4.11动物安乐死
根据AVMA Guidelines for the Euthanasia of Animals:2013 Edition(the American Veterinary Medical Association,2013),对于计划安乐死或濒死动物,采用过量CO 2安乐死,并断髓确认。
4.12人道终点
实验过程中,当肿瘤负荷超过体重的10%,平均肿瘤直径超过20mm,或肿瘤发生溃疡、坏死或感染,由研究人员根据具体情况决定是否对动物实施安乐死以及时间。
5数据采集和统计分析
数据采集:检验水准为0.05,结果分析时同时考虑统计学意义和生物学意义。肿瘤体积、RTV个体数据保留小数点后2位,其平均值、T/C%及IR TV%均按未四舍五入前的数据进行相关计算,计算结果保留小数点后2位。
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 T3 test进行组间比较分析。
动物非计划安乐死时采集的数据,以及样本数(n)小于3时,不进行统计分析。
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BT474细胞NPG小鼠皮下移植瘤)的抗肿瘤作用显著。
