Description

一种脂质化合物及脂质体与药物组合物
技术领域
本发明涉及一种脂质化合物,具体的更涉及一种脂质化合物及脂质体与药物组合物。
背景技术
siRNA技术是最广泛应用的生物学技术之一,由于siRNA技术对特定基因mRNA的高度特异性和高效性表达调控,而被广泛的用于功能基因组学、遗传学、基因治疗、病毒性疾病治疗等许多领域。然而,无论在体内还是体外,siRNA都很容易被广泛存在的RNase降解,并且siRNA无法单独穿过细胞膜引发RNAi效应,因此,siRNA技术离不开高效、低毒的siRNA运载体的帮助。常用的siRNA转染运载体有病毒载体、脂质体、高聚物、无机纳米粒子、多肽生物载体等。
当前的siRNA转染运载体多存在包载量低、穿透能力差、毒性大、质量难以控制等缺陷,需要进一步改进并提高相关技术。
发明内容
在符合本领域常识的基础上,上述各优选条件,可任意组合,而不超出本发明的构思与保护范围。
为了解决上述的技术问题,本发明的第一个方面提供了一种具有式(Ⅰ)所示结构的脂质化合物,其特征在于,式(Ⅰ)如下所示:
