Description

一种生产纳米粒子的制备系统及其制备方法
本申请要求申请日为2021/9/30的中国专利申请2021111789355的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及生物医药技术领域,具体涉及一种生产纳米粒子的制备系统及其制备方法,具体涉及的生产方法包括含有光敏剂和抗肿瘤药物的两相溶液在合并管道内合并形成合并相,并通过湍流混合装置进行充分混合,形成稳定分散的、具有一定粒径和分布系数的光敏剂与抗肿瘤药物复合纳米制剂的过程。
本发明属于纳米药物制剂技术领域。
背景技术
在肿瘤治疗过程中,有多种治疗方案可以延长肿瘤患者的生存期,治疗方案中所使用抗肿瘤药物包括化疗药物、靶向药物、光敏分子、光热分子、多肽、蛋白质、siRNA等,其中的一些药物需要制成纳米剂型才能达到治疗肿瘤的效果。常用的纳米制剂形式包括:纳米粒子、脂质体、聚合物胶束、树枝状聚合物等。
光敏剂/抗肿瘤药物复合型纳米粒子,在肿瘤治疗过程中不但能发挥抗肿瘤药物的单一疗效,同时还能起到协同治疗的作用,以下光敏剂/抗肿瘤药物复合型纳米粒子已见文献报道:Ce6-DOX复合纳米粒子(ACS Appl.Mater.Interfaces 2016,8,13262-13269)、Ce6-HCPT复合纳米粒子(Nanoscale,2017,9,14347)、Ce6-SN-38复合纳米粒子(Colloids and Surfaces B:Biointerfaces,2020,188,110722)、ICG-PTX复合纳米粒子(J.Mater.Chem.B,2019,7,6914)、ICG-PTX-UA复合纳米粒子(ACS Appl.Mater.Interfaces 2017,9,43508)、UA-LA-ICG复合纳米粒子(Acta Biomaterialia,2018,70,197)、SN-38/ICG复合纳米粒子(CN108159422B)。由于此类复合纳米粒子制备方法的复杂性导致了复合纳米粒子制备过程重现性差而难以实现放大,无法产业化生产,从而限制了此类光敏剂/抗肿瘤药物复合纳米粒子的临床使用。因此,对于光敏剂/抗肿瘤药物复合型纳米粒子连续化、规模化和可控化的制备方法亟待进一步开发。
目前纳米制剂的大规模制备方法包括高压匀质法、高剪切乳化法、微射流均质法等,但这些制备方法均为批次制备,存在工艺控制参数多,批次间重现性差,放大生产难度大等缺点。
与批次制备方法相比,纳米制剂的连续化制备方法生产方式可以在连续操作过程中形成具有可调尺寸的均匀纳米粒子,生产过程中可以通过实时监测纳米制剂质量,实时收集符合质量标准的纳米制剂。
例如,对于脂质体体系,可以利用乙醇注入法进行连续化生产。加拿大Precision NanoSystems公司的微流控装置可用于连续化制备脂质体(Langmuir,2012,28,3633),利用层流的脂质有机相和水相在错列的静态混合器中快速混合,通过参数优化可以连续化制备脂质体,但由于微流控流通管道通常在微米级,流体流动为层流条件,单通道产量极小,放大生产需多通道并联,需要控制每个脂质体生 产单元的一致性。文献(Pharm Res.,2016,33,404~416)和发明专利(CN107427791)报道的利用乙醇注入法连续制备空白脂质体的装置,可以通过调节乙醇相和水相流速,制备得到多分散系数低的空白脂质体。
对于聚合物/药物纳米粒子体系,可以通过瞬时纳米沉淀法(flash nanoprecipitation,FNP)进行连续制备(US10940118B2、CN108137819、CN108542894)。纳米沉淀法是基于动力学控制原理、利用化学工程中的流体湍流混合实现纳米粒子的快速制备,具有载药率高、制备时间短(毫秒级)、易于控制纳米粒子的尺寸、易于放大和连续化生产等特点。纳米沉淀法制备药物/聚合物纳米粒子的原理为:载体或稳定剂(通常为两亲性聚合物)和疏水性药物溶解于与水互溶的良溶剂中形成均一溶液,该溶液在固定的通道内与反溶剂(通常为水)快速混合,由于此时疏水物质在混合溶剂中为高度过饱和状态,疏水性物质在水中快速成核,成核同时与溶液中的聚合物(通常是两亲性嵌段聚合物)相互作用,聚合物对成核核心包覆形成聚合物纳米粒子,聚合物对纳米粒子起到保护作用,防止形成的纳米粒子再聚集,从而形成在水中具有良好分散性的纳米粒子(Expert Opin.Drug Deliv.,2009,6,865)。纳米沉淀法所采用的制备装置包括:封闭撞击流混合器(confined impinging jet mixer,CIJM)(Physical Review Letters,2003,91,118301;AIChE Journal,2003,49,2264)、多入口涡流混合器(multi-inlet vortex mixer,MIVM)(Mol.Pharm.,2013,10,4367;Angew.Chem.Int.Ed.Engl.,2021,60,15590)。
然而,与脂质体和聚合物纳米粒子相比,小分子光敏剂/抗肿瘤药物复合型纳米粒子微观结构大不相同:脂质体为双层磷脂结构;聚合物纳米粒子为两亲性嵌段聚合物包覆疏水药物的核壳结构;小分子光敏剂/抗肿瘤药物复合型纳米粒子为自稳定的光敏剂/抗肿瘤药物纳米聚集体。因此,纳米沉淀法是否适用于小分子光敏剂/抗肿瘤药物复合型纳米粒子的制备不可预见,需要做大量的实验进行研究、验证和优化。到目前为止,未发现采用纳米沉淀法进行连续化生产光敏剂/抗肿瘤药物复合型纳米粒子的报道。
本申请在纳米沉淀法制备聚合物/药物纳米粒子的基础上,进行了反复的研究和试验,开发了一种光敏剂/抗肿瘤药物复合型纳米粒子规模化生产的制备系统,该系统适于光敏剂/抗肿瘤药物复合型纳米粒子的连续可控放大生产。

下面通过实施例的方式进一步说明本发明,但并不因此将本发明限制在所述的实施例范围之中。
下列实施例中未注明具体条件的实验方法,按照常规方法和条件,或按照商品说明书选择。
在本文中所披露的范围的端点和任何值都不限于该精确的范围或值,这些范围或值应当理解为包含接近这些范围或值的值。对于数值范围来说,各个范围的端点值之间、各个范围的端点值和单独点值之间,以及单独的点值之间可以彼此组合而得到一个或多个新的数值范围,这些数值范围应被视为在本文中具体公开。
本申请中湍流混合部分为一定直径和长度的圆形管道,通过以下几种方式中的一种或多种达到湍流条件:
1)增加流速:
充分混合需达到湍流,Re>4000
流量Q=πd 2/4*υ
Re=ρυd/μ=4ρQ/(πdμ)>4000
当d=0.25mm
Q>πμd=2.8L/h
当d=4mm
Q>45L/h
当d=40mm
Q>450L/h
其中,Re为雷诺数,Q为流量,d为管道直径,υ为管道内流体流速,μ为流体粘度20℃μ =10 -3Pa·s
其中,需要指出的是,对于制备某些光敏剂和抗肿瘤药物复合纳米粒子,Re在500-4000范围内,也能得到一定粒径和粒径分布的纳米制剂。
2)改变管道形貌:
通过增加管道曲折程度,流体流动方向被强行变更,增强流体混合。
3)管道内增加静态混合器:
静态混合器包括但不限于:SV型静态混合器、SX型静态混合器、SL型静态混合器、SH型静态混合器、SK型静态混合器等,通过湍流混合元件对流体进行分割,改变流体流动方向,增强流体的对流,增加流体的混合。
SV型静态混合器单元是由一定规律的波纹板组装而成的圆柱体。
SX型静态混合器单元由交叉的横条按一定规律构成许多的X型单元。
SL型静态混合器单元由交叉的横条按一定规律构成单X型单元。
SK型静态混合器单元由单孔道左、右扭转的螺旋片组焊而成。
SH型静态混合器单元由由双孔道组成,单元之间设有流体再分配室。
实施例1:第一相溶液与第二相溶液的配制
示例:SN-38:ICG=2:1(摩尔比)第一相溶液的配制
第一相溶液配制:ICG 1.30g和SN-38 1.30g溶解于35.1g DMSO,总重37.7g,SN-38含量:3.4wt.%,ICG含量:3.4wt.%,SN-38与ICG摩尔比为2:1。
除特别注明外,第二相溶液为水。
实施例2:SN-38、ICG浓度测定
仪器:Agilent1260高效液相色谱仪
色谱柱:Waters XBridge C18 4.6*150mm,3.5μm
流动相:以10mmol/L磷酸二氢钠溶液(磷酸调节pH4.0)为A相,以乙腈为B相,按照下表进行梯度洗脱:
时间(min) A% B%
0 80 20
10 20 80
11 80 20
16 80 20
色谱参数:流速:1ml/min;柱温:35℃;检测波长:264nm;进样量:10μl
稀释剂:DMSO
供试品溶液:以移液枪精密吸取SN-38/ICG纳米制剂溶液200μl,置10ml量瓶中,加DMSO使溶解并定量稀释至刻度,摇匀,即得。
对照品溶液:取ICG或SN-38对照品约10mg,精密称定,置100ml量瓶中,加DMSO使其溶解并定量稀释至刻度,摇匀,即得。
计算方法:峰面积外标法
除特殊说明外,其余化合物均以此流动相测定,波长视具体化合物而定。
实施例3:纳米粒子粒径测定
动态光散射法:纳米粒子浓度为10~100μg/ml,以纳米粒径仪测定纳米粒子粒度及分布(激光光源633nm),每个样品测量三次,计算纳米粒子粒径平均值和方差。不同纳米粒子的粒径分布具体可参见图3-图43以及图45-图48,附图中三条不同的曲线代表样品分别测量三次的结果。
由于光敏剂分子通常对动态光散射仪激光光源(633nm)具有一定吸收,导致拟合图中截距偏低, 同一样品三次测量结果间有一定偏差,因此采用三次测量取平均值方式减少偏差,图中微米范围内峰通常为灰尘导致。
实施例4:疏水药物包封率测定
示例:SN-38包封率测定
取1ml SN-38/ICG溶液,以0.22μm尼龙针式过滤器过滤,HPLC测定SN-38浓度。

对比例1:薄膜水化法制备PTX/ICG纳米粒子
称取15.72mg紫杉醇与36.42mg ICG于50ml茄形瓶中,以5ml甲醇溶解,紫杉醇质量分数~30wt.%。60度旋蒸除去甲醇,抽真空除去残余溶剂。加入7.860ml 60度预温的去离子水,60度下进行旋转水化,无法得到均一的PTX/ICG纳米粒子。
而公开的文献表明mPEG 2k-PLA 2k和PTX可通过薄膜水化法以30wt.%载药量以及大于90%包封率形成~20nm的PTX/mPEG-PLA胶束。
