Definitions
- the invention relates to the field of biomedicine and materials, and in particular to a cyanoacrylate material loaded with an antitumor drug.
- Intratumoral injection therapy is a new treatment plan for cancer in recent years. By directly injecting drugs into tumors and making them play a role in fixed-point treatment, it can avoid or reduce the first-pass effect that oral and intravenous injections need to face. And systemic side effects and so on. Treatments with intratumoral injections have unique advantages in areas that are not accessible with open surgical instruments, as well as those that are not conducive to surgical resection, or where postoperative aesthetics are considered.
- the approved tumor-removing virus therapy such as Amgen's IMLYGIC, domestically-born, and Ankerui, all use intratumoral injection.
- a number of drug development studies have also been administered intratumorally, such as MultiVir's intratumoral injection of the drug Ad-IL-24 for the treatment of head and neck tumors.
- existing clinically relevant technical means are mature, and multi-site intratumoral injection can be realized.
- B-ultrasound, CT, magnetic resonance and other images minimally invasive treatment of tumor puncture can be achieved.
- the intratumoral pressure is higher than normal tissue, the liquid drug is likely to overflow after being injected into the tumor, and the second is that the tumor is rich in blood vessels. After the drug spreads quickly from the tumor site to other tissues, the purpose of long-term administration is not achieved.

Abstract
一种负载抗肿瘤药物的氰基丙烯酸酯材料,以及含有所述氰基丙烯酸酯材料和抗肿瘤药物的组合物,包含所述组合物的药物制剂,例如可用于肿瘤内注射的药物制剂。
Description
本发明涉及生物医学领域和材料领域,具体涉及一种负载抗肿瘤药物的氰基丙烯酸酯材料。
肿瘤瘤内注射治疗是近年发展的肿瘤治疗新方案,通过将药物直接注射到肿瘤内,使其发挥定点治疗的作用,可一定程度上避免或减轻口服、静脉注射等手段需要面临的首过效应和全身毒副作用等。在一些不采用开放性手术器械就可到达的部位,以及一些不利于手术切除的部位,或者在考虑到术后美观程度等情况下,采用瘤内注射药物的治疗方案具有独特的优势。
已批准上市的融瘤病毒疗法,如安进公司的IMLYGIC、国内的今又生、安柯瑞等新药都是采用瘤内注射方法。此外,多项药物开发研究也采用了瘤内注射给药,如MultiVir公司采用瘤内注射的方式输送治疗头颈瘤的药物Ad-IL-24。再者,现有临床相关技术手段成熟,可实现多部位的瘤内注射,如在B超、CT、磁共振等影像引导下可实现肿瘤穿刺微创治疗,临床已有氩氮刀冷冻、射频加热等手段可使用。
但是,瘤内注射的方案中,有两个风险问题需要引起特别关注,一是由于瘤内压力高于正常组织,因此液体药物注射到瘤内后容易溢出,二是肿瘤内血管丰富,给药后药物容易较快地从肿瘤部位扩散至其他组织,达不到长效给药的目的。
因此,提供瘤内注射的新制剂或新材料,避免药物溢出的风险,实现长时间瘤内定点缓释给药具有实际应用价值。

实施例1配方胶的制备
使用氰基丙烯酸酯单体BCA、MOE-CA、CA-TEG-CA、CA-PEG
600-CA、CA-PEG
2000-CA,按照表1中的配方制备配方胶。在氮气保护的条件下,将对应的单 体成分通过搅拌、振荡等方式混合,可获得澄清透明的配方胶。配方胶在常温常压、空气中发生聚合,形成胶块。对胶块的降解速率和粘接强度进行测试,结果见表1。
各单体的结构如下:
表1 配方胶的组成以及胶块的降解速率和粘接强度
a.表观降解速率测试方法:将聚合物胶块称重(W
0),放置在50毫升PBS溶液中,在37℃恒温摇床(荣华)中震摇14天后,干燥称重(W
1)。表观降解速率=(W
0–W
1)/W
0
b.按照标准规定“YYT 0729.1-2009组织粘合剂粘接性能试验方法”进行测试。
c.表示24小时聚合物即完全消失溶解。
从表1中可以看到,不同结构的胶块具有差异性的表观降解速率和粘接强度(剪切拉伸)。在实际使用中,可以根据特定的需要(例如需要胶块具有一定的降解速率或粘接强度)选择合适的单体配方。
实施例2载药胶的制备
将表1中的配方胶分别与氟尿嘧啶、姜黄素、多柔比星、紫杉醇、多烯紫杉醇混合,各个药物均采用多个质量比(0.1%、0.25%、0.5%、0.75%、1%、1.25%、1.5%、2%、2.5%),均可获得澄清透明的载药胶溶液。
实施例3不同单体配方的载药胶的体外药物释放试验
以含1.25%的氟尿嘧啶的载药胶溶液为例。在A组、F组、G组、I组、J组、K组、M组的配方胶中,分别加入1.25%质量比的氟尿嘧啶,混合均匀,可得澄清溶液状载药胶。取0.1g载药胶溶液,聚合为胶块(面积2.5×1cm
2),置于50mL PBS溶液中(pH7.4),再将含有胶块的溶液放入37℃条件下的恒温摇床(SHZ-82A,JINTAN RONGHUA,China,60rpm)。一定时间点取样,测试溶液中的氟尿嘧啶含量,进而计算得到各组的药物释放量。氟尿嘧啶的含量测定:首先通过高效液相的方法,配置不同浓度标准品,绘制峰面积-浓度标准曲线(图1),再通过测定具体样品中的峰面积从而计算获得对应浓度。结果如表2、表3、表4所示。
表2 M组、A组、F组、K组的体外药物释放量(%)
从表2可以看出,同一种单α-氰基丙烯酸酯以相同的比例与不同的双α-氰基丙烯 酸二酯组合,可以得到释药速率不同的载药胶。
表3 I组、J组、K组的体外药物释放量(%)
表4 G组、F组的体外药物释放量(%)
从表3和表4可以看出,同样的单α-氰基丙烯酸酯与双α-氰基丙烯酸二酯以不同的比例组合,可以得到释药速率不同的载药胶。
从表2、表3、表4中可以看出,不同结构的聚氰基丙烯酸酯材料均能够将药物释放出来,但不同的配方制得的载药胶具有不同的药物释放速率,这可能与聚合物的降解性质、微观结构上的致密程度以及材料与药物分子的相互作用力相关。可以通过 调节单体的组成和含量,对药物的释放速率进行调节。
实施例4不同药物浓度的载药胶的体外释放试验
取J组配方胶,加入0.3125%、0.625%或1.25%的氟尿嘧啶,按照实施例3中的方法,测试载药胶块的体外释放曲线,结果如图2所示。从图中可以看出,负载不同浓度药物的载药胶块(J-Fu-0.3125、J-Fu-0.625、J-Fu-1.25)具有相似的药物释放曲线,说明同样单体配方的载药胶,其药物释放行为比较稳定,受到药物浓度的影响较小,可以根据需要灵活地调节药物浓度。
实施例5体外抗肿瘤试验
材料浸提液制备:取7.5mg不含药物的J组配方胶(简称为J组),以及负载不同浓度(1.25%,0.625%和0.3125%)氟尿嘧啶的J组配方胶(分别简称为J-Fu-1.25,J-Fu-0.625,J-Fu-0.3125),于48孔细胞培养板(直径10.2mm)中固化完全后,以生理盐水(7.5mg/mL)置于37℃、体积分数5%CO
2培养箱中浸提24h;浸提液以0.22μm无菌滤膜过滤,加入RPMI-1640培养基,按照(1/1,v/v)进行稀释,得到待测样品。
体外细胞试验:MCF-7细胞购自协和细胞库;用0.25%胰蛋白酶消化单层培养的传代48h生长旺盛的MCF-7细胞,用含10%胎牛血清的RPMI-1640培养基配成单个细胞悬液,以5×10
3个细胞接种于96孔培养板中,每孔体积100μL,放入二氧化碳恒温培养箱,在37℃、5%CO
2及饱和湿度条件下培养24h至细胞贴壁;吸取培养液,将100μL待测样品加入到培养板各个孔中,其中,阴性对照为含有10%胎牛血清的RPMI-1640培养基(正常组);阳性对照为含有1.25%氟尿嘧啶的PBS溶液(简称为Fu组);采用MTT(四甲基偶氮唑盐)法检测细胞存活率。
图3显示了各组的细胞存活率,图4为显微镜观察到的细胞形态,其中,A:J组,B:J-Fu-1.25组,C:J-Fu-0.625组,D:J-Fu-0.3125组,E:正常组,F:Fu组。
从图3和图4的试验结果可以看出,相比于阴性对照组,负载不同浓度氟尿嘧啶的载药胶对MCF-7均显示出一定的抑制活性,并且,从图3可以看出,J-Fu-1.25组显示出比阳性对照更强的抑制活性,说明,氰基丙烯酸酯单体和/或聚合物对氟尿嘧啶的疗效产生了促进作用。
实施例6裸鼠体内抗肿瘤试验
模型构建:取40只Balb/c裸鼠(8周龄,雌性,20g左右),将200μL2×10
6MCF-7细胞悬液(生理盐水)以一次性塑料注射器(1mL)皮下注射至Balb/c裸鼠右前肢腋下,正常饲养15天。
给药及药效评价:将40只Balb/c肿瘤裸鼠随机分为四组,每组10只。其中,PBS组:瘤内注射60μL PBS溶液;Fu组:瘤内注射60μL含有1.25%氟尿嘧啶的PBS溶液;J组:瘤内注射60μL空白J组配方胶;J-Fu-1.25组:瘤内注射60μL含1.25%氟尿嘧啶的J组配方胶。观察随时间变化每组小鼠的肿瘤体积大小、体重变化、生存率,其中肿瘤体积大小(V)计算方法为V=短径
2×长径×0.5。
图5显示了各组小鼠肿瘤体积变化;图6显示了各组小鼠的存活率;图7显示了各组小鼠的体重变化;图8显示了试验第14天各组小鼠肿瘤情况,其中,A:PBS组,B:Fu组,C:J组,D:J-Fu-1.25组。
从图5-7的数据可以看出,相比于其他三组,载药胶J-Fu-1.25有效地抑制了肿瘤的生长,提高了小鼠的生存率,且在试验期间小鼠的体重未发生明显变化。从图8可以看出,给药后第14天,相比于其他三组,J-Fu-1.25组小鼠的肿瘤出现更多的炎症、坏死现象。上述结果共同说明了载药胶J-Fu-1.25具备良好的抗肿瘤效果。
此外,从图5-7可以看出,J-Fu-1.25组的抗肿瘤效果优于Fu组,也优于J组。上述结果说明,至少在一定剂量范围内下,氰基丙烯酸酯单体和/或聚合物可以对氟尿嘧啶发挥促进作用,二者组合可以产生协同抗肿瘤的作用。
参照上述模型构建方法和给药方法,对D、I、J、K、L、M、N和R组进行试验,结果如表5所示。
表5
实施例7安全性评价
试验一、Balb/c裸鼠肿瘤内植入试验
在实施例6的体内抗肿瘤试验给药第40天时,将存活的J-Fu-1.25组小鼠全部脱 臼处死,取其心、肝、脾、肾等主要脏器,以福尔马林固定,通过对组织进行H&E染色,病理分析J-Fu-1.25的系统毒性。图9为主要脏器的H&E染色照片。从图中可以看出,给药后第36天,J-Fu-1.25组Balb/c裸鼠主要脏器(心、肝、脾、肾)H&E染色未观察到炎症情况,相比于正常动物对照组,无显著差异,说明J-Fu-1.25无系统毒性。
试验二、SD大鼠背部皮下植入试验
将20mg液态的J-Fu-1.25配方胶在室温条件下固化为圆形聚合物胶块(直径为60mm);取18只SD大鼠(220g左右,雌性),以10%水合氯醛麻醉后,脱去背部毛发,将聚合物胶块皮下植入SD大鼠背部皮肤,观察随时间变化(2天,4天,6天,10天,14天,30天;每个时间点3只动物)聚合物胶块接触的皮肤、肌肉的炎症情况。将大鼠脱臼处死,取下皮肤、肌肉以及大鼠脏器(心、肝、脾、肾)进行H&E染色病理分析。
图10显示了试验第30天皮肤、肌肉以及大鼠脏器的H&E染色照片。虽然在试验后的前几天时间里,观察到胶块植入部位出现一定程度的炎症,但在试验第30天,所有的试验大鼠均存活下来,炎症部位恢复正常,且从图10可以看出,聚合物胶块接触的皮肤、肌肉以及大鼠的主要脏器(心、肝、脾、肾)均未观察到炎症情况,说明植入的聚合物胶块无系统毒性。
上述两个试验结果共同证实了:本发明的载药聚合物胶块具有良好的生物相容性。
尽管本发明的具体实施方式已经得到详细的描述,但本领域技术人员将理解:根据已经公开的所有教导,可以对细节进行各种修改和变动,并且这些改变均在本发明的保护范围之内。本发明的全部范围由所附权利要求及其任何等同物给出。
