Liposomal compositions comprising of liposomes of guanidinylated cationic amphiphiles as the main lipid and cholesterol/1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)/aminopropyl polyethyleneglycol carbamyl-distearoylphosphatidyl-ethanolamine (DSPE-peg-NH2) as co-lipids are described. These liposomal compositions containing encapsulated or electrostatically complexed therapeutic small interfering RNAs (siRNAs) against Cdc20, a key cell cycle regulator, inhibit solid tumor growth and melanoma tumor growth on lung in C57BL/6J mice.
本研究描述了由
胍基阳离子两性化合物脂质体作为主脂质和
胆固醇/1,2-二油酰-sn-
甘油-3-
磷脂酰
胆碱(
DOPC)/
氨基丙基聚
乙二醇氨基甲酰-
二硬脂酰磷脂酰乙醇胺(D
SPE-peg-NH2)作为辅脂质组成的脂质体组合物。这些脂质体组合物含有针对细胞周期关键调节因子 Cdc20 的包封或静电络合治疗性小干扰 RNA(siRNA),可抑制 C57BL/6J 小鼠肺部实体瘤和
黑色素瘤的生长。
