Description

新型氘代PEG脂质化合物、其制备方法、组合物和应用 技术领域
本发明提供新型氘代聚合物缀合脂质,其可用于与其他脂质组分(如中性脂质、类固醇和阳离子的脂质)结合,以便形成一种核酸mRNA脂质纳米粒子组合物将一种或多种治疗剂和/或预防剂递送至哺乳动物细胞或器官和/或在哺乳动物细胞或器官中产生多肽的方法。除新型氘代脂质外,本发明的脂质纳米粒子组合物还可以包括呈特定比例的一种或多种氘代聚合物缀合脂质、包括多不饱和脂质在内的中性脂质、阳离子脂质、类固醇、和/或治疗剂和/或预防剂。
背景技术
生物活性物质如小分子药物、蛋白质和核酸的有效靶向递送提出了一个持久的医学难题。确切地说,将核酸递送至细胞因这些物种的相对不稳定性和低细胞渗透性而变得困难。因此,需要开发有助于将治疗剂和/或预防剂如核酸递送至细胞的方法和组合物。
经研究证明,利用含脂质的纳米颗粒组合物、脂质体和脂质体复合物作运输媒介,可有效地将生物活性物质如小分子药物、蛋白质和核酸运送至细胞和/或细胞内隔室中。这些组合物一般包含一种或多种聚合物缀合的脂质,包括多不饱和脂质在内的中性脂质(如磷脂)、结构性脂质(如类固醇)和/或含阳离子的脂质。
然而,在治疗环境中使用寡核苷酸目前面临着两个问题。第一,游离的RNA易于在血浆中核酸酶消化。第二,游离RNA进入存在相关翻译机制的细胞内隔室的能力受限。由PEG化的氘代脂质与其他脂质组分(如中性脂质、胆固醇、阳离子脂质和寡核苷酸)形成的脂质纳米颗粒已用于阻止RNA在血浆中的降解并促进寡核苷酸的细胞摄取,而氘代的聚合物缀合脂质未有报道。
所以,仍然有必要改进的用于递送寡核苷酸的氘代聚乙二醇化的脂质和脂质纳米颗粒。改进的脂质化合物和脂质纳米颗粒会改进理化性质,提供优化的药物递送,保护核酸不在血清中被降解和清除,其适于全身或局部递送,并且提供核酸的细胞内递送。另外,这些优选的脂质-核酸颗粒应当是耐受良好的,并且提供足够的治疗指数,使得在有效剂量的核酸下的患者治疗不会对患者产生不可接受的毒性和/或风险。本发明提供这些优点和相关的优点。

利用脂质纳米颗粒组合物的荧光素酶mRNA体内评价
将阳离子脂质、DSPC、胆固醇和氘代PEG-脂质以50:10:38:2或48:10:40:2的摩尔比溶解在乙醇中,其中阳离子脂质如E结构式、F结构式所示。以约10:1至30:1的总脂质与mRNA的重量比制备脂质纳米颗粒(LNP)。简而言之,将mRNA在10ml至50ml柠檬酸盐缓冲液(pH=4)稀释至0.15mg/mL。使用注射器泵,将脂质的乙醇溶液与mRNA水溶液以约1:5至1:3(体积/体积)的比例混合,总流速为10ml/min以上。然后去除乙醇,并通过透析用PBS替代外部的缓冲液。最后,将脂质纳米颗粒通过0.2μm孔径的无菌过滤器过滤。使用Malvern Zetasizer Nano ZS通过准弹性光散射测定的脂质纳米颗粒的粒径为直径大约65-105nm,并且在一些情况下,直径大约75-100nm。

根据国家科学技术委员会制定的指南,在6-8周龄的雌性C57BL/6小鼠,8-10周龄CD-1小鼠上进行研究。通过尾静脉注射全身性给予不同剂量的mRNA脂质纳米颗粒,并在给药后的特定时间点(例如5小时)将动物安乐死。将肝脏和脾脏收集在预先称重的管中,确定重量,立即在液氮中快速冷冻,并且在-80℃下储存,直至用于分析。
对于肝脏,切割约50mg以便在2mL FastPrep管(MP Biomedicals,Solon OH)中进行分析。向各个管中加入1/4"陶瓷球(MP Biomedicals),并将平衡至室温的500μL的Glo裂解缓冲液-GLB(Promega,Madison WI)加入到肝脏组织中。使用FastPrep24仪器(MP Biomedicals)将肝脏组织在2×6.0m/s下均匀化15秒。将匀浆在室温下孵育5分钟,然后在GLB中进行1:4稀释,并使用SteadyGlo荧光素酶测定系统(Promega)进行评估。具体地,将50μL的稀释的组织匀浆与50μL的SteadyGlo底物反应,摇振10秒,接着孵育5分钟,然后使用SpectraMAX_L化学发光型酶标仪(美谷分子仪器(上海)有限公司)定量。通过使用BCA蛋白质定量试剂盒(上海易色医疗科技有限公司)来确定测定的蛋白质的量。然后将相对发光度单位(RLU)归一化成所测定蛋白质的总μg。为了将RLU转化成μg荧光素酶,用QuantiLum重组荧光素酶(Promega)生成了标准曲线。
来自Trilink Biotechnologies的FLuc mRNA(L-6107)将表达荧光素酶蛋白,其最初从萤火虫(Photinus pyralis)中分离出来。Fluc通常用于哺乳动物细胞培养物中以测量基因表达和细胞活力。其在底物萤光素存在下发射出生物性光。这种加帽并且聚腺昔酸化的mRNA被5-甲基胞苷和假尿苷完全取代。

使用体内荧光素酶mRNA表达的啮齿动物模型测定含有各种阳离子脂质的脂质纳米颗粒制剂的效能
为了比较的目的,如实施例83所述,使用有序混合方法,将这些脂质也用于配制含有FLuc mRNA(L-6107)的脂质纳米颗粒。使用以下摩尔比来配制脂质纳米颗粒:50%阳离子脂质/10%二硬脂酰磷脂酰胆碱(DSPC)/38%胆固醇/2%氘代PEG脂质。如实施例83所述,在经由尾静脉注射施用之后的5小时,通过测量肝脏中的荧光素酶表达来确定相对活性。在0.3和1.0mg mRNA/kg的剂量下比较所述活性,并表达成在如实施例83所述的施用之后5小时测量的ng荧光素酶/g肝脏。实施例83及84结果如表2所示。
