Chemical synthesis of super messenger RNA medicine

ABSTRACT

Messenger RNA(mRNA)medicine was urgently approved in 2020 as a vaccine for COVID-19 . However, current mRNA therapeutics are not fully established, with challenges remaining in translation efficiency and drug delivery system. Therefore, further research is needed to adapt mRNA therapeutics to other diseases. Furthermore, the preparation of mRNA drugs is time-consuming and costly because of the biological methods used. Our laboratory has been working on chemical methods to solve these issues. In this paper, we introduce chemical modifications and novel capping reactions as a method to improve the translation efficiency of mRNA and the introduction of disulfide modification to oligonucleotide therapeutics as an effort on the drug delivery system.Copyright © 2023, Japan Society of Drug Delivery System.
