Description
本申请要求2021年5月28日向中国国家知识产权局提交的专利申请号为202110592439.8,发明名称为“化合物及其在核酸递送中的应用”的在先申请的优先权。该在先申请的全文通过引用的方式结合于本申请中。
技术领域
本发明属于药用化合物技术领域,具体涉及一种可电离脂质化合物、其制备方法,以及其在活性治疗剂(例如核酸)递送中的应用。
背景技术
核酸包括小干扰RNA(siRNA)、信使RNA(mRNA)、微RNA(miRNA)、反义寡核苷酸(ASO)、核酶、质粒和免疫刺激性核酸,通过多种机制发挥作用。以mRNA为例,mRNA是将遗传信息从DNA转运至细胞质的核糖体进行蛋白质翻译的一类RNA,它无需进入细胞核,因此不会带来基因突变的风险,可以用于实现特定细胞产物的表达。这些核酸在与蛋白质或酶的缺陷相关疾病的治疗中是有用的。然而,在治疗环境中核酸会遇到很多问题。例如mRNA,其为单链结构非常不稳定,进入体内后很快会被核酸酶降解。此外,mRNA具有较大的分子量且带有大量负电荷使其难以穿过带负电荷的细胞膜进入靶细胞。所以如何将mRNA有效地递送到细胞是实现其体内应用的技术关键。类似的问题在各种治疗性核酸中均存在。
在基因治疗中,可电离脂质化合物已经被证明是治疗各种疾病的核酸的优良递送载体。所述可电离脂质化合物的胺基在合适的酸性条件下可以质子化形成带正电头基,其尾部由疏水性碳链组成,带电部分用来以静电方式结合带负电RNA,同时疏水性尾部使得其能自组装成亲脂性粒子。可电离脂质化合物和其他三种或四种脂质如DSPC(二硬脂酰基磷脂酰胆碱)或DOPE(二油酰磷脂酰乙醇胺)、胆固醇(CHOL)和PEG化脂质[DMG-PEG2000(1,2-二肉豆蔻-rac-甘油-3-甲氧基聚乙二醇2000)或DSPE-PEG2000(二硬脂酰基磷脂酰乙醇胺-聚乙二醇2000)]组合而自组装形成的脂质纳米颗粒(lipid nanoparticle,LNP)用来递送核酸,可以保护核酸避免被核酸酶降解,并且促进细胞摄取。目前可电离脂质化合物在核酸递送中取得了巨大进步,但仍存在递送效率较低的问题,这也是制约行业发展的瓶颈问题之一。
发明内容
本发明提供了一种新型可电离脂质化合物,其可用于递送生物活性分子(例如,mRNA,siRNA,micRNA,蛋白质,多肽等)。鉴于胺基结构可质子化形成带正电荷的阳离子基团,本发明的可电离脂质化合物尤其适用于传递带负电荷的活性物质,例如DNA、RNA或其它核苷酸分子。

实施例2可电离脂质Ⅱ-37的解离常数(pKa)
可电离脂质有两个主要作用:结合核酸和允许核酸分子在细胞中释放。脂质的pKa是一个重要因素,因为脂质需要在低pH值下带正电荷才能与核酸结合,但在中性pH值下不带电荷,才能使形成的LNP不会引起毒性。通过TNS染料结合试验测定可电离脂质Ⅱ-37的pKa在6.81,结果如图1所示。
实施例3 Ⅱ-37包裹mRNA制备脂质纳米颗粒
可电离脂质Ⅱ-37、DSPC、CHOL和DMG-PEG2000分别按照摩尔比35%:15%:48.5%:1.5%配置乙醇溶液作为有机相,把Lucferase mRNA(LucRNA)溶于pH=4的水溶液作为水相。按照水相和有机相的体积比为3:1,在纳米药物制造仪(加拿大PNI公司,Ignite型号)上用微流控技术制备得到纳米颗粒混悬液。制备完后再超滤浓缩得到最终的LucRNA-LNP脂质纳米颗粒,保存于2-8℃备用。

LucRNA-LNP | 108.66 | 0.13 | 17.87 | 96.4% | 1088112 |
从实施例3的结果可以看出,由新型脂质化合物配伍制备的脂质纳米颗粒LucRNA-LNP粒径在108nm左右,LucRNA-LNP粒径分布较窄(PDI较小),包封率高达96%。体外细胞转染效率高达100万。表明由可电离脂质II-37制备的LNP包裹mRNA不仅具有非常好的理化参数,还具有极高的细胞转染效率。

实施例6 II-37和商业化可电离阳离子脂质分子MC3的效果对比
MC3的分子式为:4-(N,N-二甲基氨基)丁酸(6Z,9Z,28Z,31Z)-庚三十碳-6,9,28,31-四稀-19-基脂。
按照实施例3所述的方法,分别使用II37和MC3制备脂质纳米颗粒,具体摩尔配比为:II-37:DSPC:CHOL:DMG-PEG2000=45:15:38.5:1.5;MC3:DSPC:CHOL:DMG-PEG2000=45:15:38.5:1.5;N/P比为5:1。
制备得到的脂质纳米颗粒理化质控数据如下表所示:
样本信息 | 粒径(nm) | PDI | Zeta电位 | 包封率 |
mRNA-LNP(II-37) | 154.58 | 0.1068 | 22.07 | 90.5 |
mRNA-LNP(MC3) | 234.08 | 0.1259 | 2.44 | 40.7 |
由上表可见,II-37制备的脂质纳米颗粒包封率高达90.5%,远高于MC3的脂质纳米颗粒,并且粒径更小更均一,电位更高。
采用实施例3相同的转染方式,将制备的脂质纳米颗粒转染细胞CHO-K1,了解蛋白的表达情况,结果如图5所示,在转染的mRNA量相同的情况下,II-37(图中以C2表示)制备的脂质纳米颗粒携带mRNA转染细胞之后,细胞中蛋白表达量远远高于MC3的,说明II-37制成的脂质纳米颗粒的细胞转染效率很高。
此外,用Cy5标记负载的mRNA得到Cy5-mRNA-LNP(II-37)和Cy5-mRNA-LNP(MC3)。与293T细胞共孵育2h和6h后,以LysoSensorTM Green对细胞溶酶体进行染色,观察Cy5-mRNA入胞效果。由图6可见,Cy5-mRNA-LNP(II-37)与细胞孵育6h后,Cy5-mRNA大多数到达溶酶体,共定位系数达0.626;Cy5-mRNA-LNP(MC3)与细胞孵育6h后,Cy5-mRNA入胞较少,由此对比可知,II-37分子的核酸递送效率优于MC3分子。
从实施例6的结果可以看出,由新型脂质化合物配伍制备的脂质纳米颗粒在核酸递送效率和体外细胞转染效率均优于MC3分子。
实施例7 II-37和其结构类似物分子C14-113的对比
C14-113的结构式为:
按照实施例3所述的方法,分别使用II37和C14-113制备脂质纳米颗粒,具体摩尔配比为:II-37:DSPC:CHOL:DMG-PEG2000=45:15:38.5:1.5;C14-113:DSPC:CHOL:DMG-PEG2000=45:15:38.5:1.5;N/P比为10:1。
制备得到的脂质纳米颗粒理化质控数据如下表所示:
样本信息 | 粒径(nm) | PDI | Zeta电位 |
mRNA-LNP(II-37-LNP) | 136.68 | 0.14 | 20.07 |
mRNA-LNP(C14-113-LNP) | 152.65 | 0.12 | 24.1 |
采用实施例3相同的转染方式,将制备的脂质纳米颗粒转染细胞293T,了解蛋白的表达情况,结果如图7所示,在转染的mRNA量相同的情况下,II-37(图中以II-37-LNP表示)制备的脂质纳米颗粒携带mRNA转染细胞之后,细胞中蛋白表达量远远高于C14-113的,说明II-37制成的脂质纳米颗粒的细胞转染效率很高。
此外,采用MTT法测定II-37-LNP和C14-113-LNP的细胞毒性,考察载体剂量、作用时间等因素对正常细胞(293T)细胞增殖的影响。结果如图8所示,II-37(图中以II-37-LNP表示)制备的脂质纳米颗粒携带mRNA转染细胞48小时之后,在较高的剂量(2μg/mL)时依然保持较好细胞活性,说明II-37制成的脂质纳米颗粒的细胞毒性很低。
从实施例7的结果可以看出,由新型脂质化合物配伍制备的脂质纳米颗粒细胞毒性低,且在mRNA转染效率优于结构类似物分子C14-113。
以上,对本发明的实施方式进行了说明。但是,本发明不限定于上述实施方式。凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
