Nucleic Acid Drugs Preparation

Due to their low immunogenicity, biocompatibility, and high encapsulation efficiency for oligonucleotide molecules, lipids and their derivatives have become the go-to delivery systems for nucleic acid drugs that have attracted much attention in recent years. The system is positively charged in the physiological environment. The negatively charged nucleic acid molecules are encapsulated by electrostatic action, and the positively charged surface can also help the entire carrier system to combine with the cell membrane of the target cell, thereby playing a delivery role.

Traits of Successful Delivery Systems

  ❖ Easily modified, easily synthesized, easily produced.

  ❖ The on-target and off-target ratio of delivery should be within an acceptable range.

  ❖ The effective dose must be significantly lower than the toxic dose.

  ❖ The bioactivity of the nucleic acid should be consistent from batch to batch.

  ❖ In most clinical cases, repeated administration does not result in loss of efficacy or safety.
