Abstract
Description
본 발명은 5'-캡핑된 RNA의 합성에 사용되는 신규 올리고뉴클레오티드에 관한 것이다.The present invention relates to novel oligonucleotides used for the synthesis of 5'-capped RNA.
RNA의 5'-캡핑이란 진핵세포 내에서 pre-mRNA 가공 과정의 첫번째 단계로, 전사된 RNA의 5' 말단에 캡(cap)이 씌워지는 과정이다. 진핵생물에서 mRNA 분자의 5' 말단에는 7-메틸구아노신(m7G)이 5' 트리포스페이트 결합을 통해 연결된 5' 캡(cap-0)이 생성되며, 이는 생체 내에서 메틸트랜스퍼라제 효소에 의해 매개된다. 진핵생물의 mRNA에는 5' 말단의 첫번째 리보오스 당의 2' 히드록시기의 메틸화(cap-1) 및 두번째 리보오스 당의 2' 히드록시기의 메틸화(cap-2)를 포함하는 추가적 변형이 존재할 수 있다. 이러한 mRNA의 5' 캡핑 과정을 통해 mRNA가 핵에서 세포질로 빠져나갈 때 5' 엑소뉴클레아제 등의 분해효소에 대한 저항성을 획득한다.RNA 5'-capping is the first step in the pre-mRNA processing process in eukaryotic cells, and is a process in which a cap is placed on the 5' end of the transcribed RNA. In eukaryotes, at the 5' end of the mRNA molecule, a 5' cap (cap-0) is formed in which 7-methylguanosine (m 7 G) is linked through a 5' triphosphate bond, which is in vivo in the methyltransferase enzyme. mediated by Eukaryotic mRNAs may have additional modifications, including methylation of the 2' hydroxy group of the first ribose sugar at the 5' end (cap-1) and methylation of the 2' hydroxy group of the second ribose sugar (cap-2). Through this 5' capping process of mRNA, when mRNA escapes from the nucleus to the cytoplasm, resistance to degrading enzymes such as 5' exonuclease is acquired.
의학적 또는 연구적 목적을 위해, 특정 유전자를 코딩하는 캡핑된 mRNA를 진핵 생물에 트랜스펙션하거나 세포 또는 배아로 미세주입함으로써 상기 유전자를 인위적으로 발현시킬 수 있다. 그러나, 이 과정에서 캡핑되지 않은 RNA가 사용될 경우, RNA는 빠르게 분해될 뿐만 아니라 면역원성을 가지며 단백질 번역 효율이 급격히 감소된다. 따라서, in vitro에서 mRNA를 합성하기 위해 5' 캡핑이 적절히 수행되는 것은 매우 중요하다.For medical or research purposes, capped mRNA encoding a particular gene can be artificially expressed by transfecting eukaryotes or microinjecting into cells or embryos. However, when uncapped RNA is used in this process, the RNA is not only rapidly degraded, but also immunogenic, and protein translation efficiency is drastically reduced. Therefore, it is very important that 5' capping is performed properly to synthesize mRNA in vitro.
mRNA 합성을 위해, 5'-트리포스페이트기를 갖는 RNA를 먼저 in vitro에서 전사시킨 다음, 캡핑 효소를 사용하여 5' 캡핑을 수행하는 과정은 비용이 많이 들 뿐만 아니라 비효율적이라는 점이 판명되었다. 이에 따라, 5'-캡핑 구조를 갖는 올리고뉴클레오티드를 제조하고 이를 프라이머로 사용하여 in vitro 전사를 개시하는 합성 방법이 개발되었다. 예컨대, 국제공개공보 WO2008/016473 및 국제공개공보 WO2013/059475는 5'-캡핑된 RNA를 합성하기 위한 디뉴클레오티드 mRNA 캡 유사체를 개시하고, 국제공개공보 WO2017/053297은 5'-캡핑된 RNA를 합성하기 위한 트리뉴클레오티드 mRNA 캡 유사체를 개시한다.For mRNA synthesis, it has been found that the process of first transcribing RNA having a 5'-triphosphate group in vitro and then performing 5' capping using a capping enzyme is expensive and inefficient. Accordingly, a synthetic method for initiating in vitro transcription by preparing an oligonucleotide having a 5'-capped structure and using it as a primer has been developed. For example, International Publication WO2008/016473 and International Publication WO2013/059475 disclose dinucleotide mRNA cap analogs for synthesizing 5'-capped RNA, and International Publication WO2017/053297 synthesizes 5'-capped RNA. Disclosed are trinucleotide mRNA cap analogs for
캡핑된 RNA 전사체는 핵산 치료제, 백신 분야와 같이 단백질 합성을 필요로 하는 치료 및/또는 예방 분야에 적용될 수 있으므로, 이를 효율적으로 제조하기 위한 5'-캡핑용 올리고뉴클레오티드 프라이머 개발이 필요하다. 예컨대, 종래 방법보다 제조 공정이 간편하고 비용 효율적이거나, 원하는 전사 반응을 효율적으로 진행시키거나, RNA 생성 수율을 향상시키거나, 원하지 않는 이종 생성물의 생성을 감소시키거나, 추가적인 효소 반응을 필요로 하지 않거나, RNA의 대규모 합성을 가능하게 하는 RNA 캡 유사체의 개발이 절실한 실정이다. 나아가, 실제 RNA 치료제 또는 백신으로 적용될 때 생체 내에서 mRNA 안정성을 유지하거나 번역 효율을 개선하거나 면역원성 등의 부작용을 감소시킬 수 있는 캡 구조를 제공한다면, RNA 치료제 또는 백신 분야에서 범용적인 유용성이 달성될 수 있을 것이다.Since capped RNA transcripts can be applied to therapeutic and/or preventive fields requiring protein synthesis, such as nucleic acid therapeutics and vaccines, it is necessary to develop 5'-capping oligonucleotide primers to efficiently prepare them. For example, the manufacturing process is simpler and more cost-effective than conventional methods, efficiently proceeds with a desired transcription reaction, improves RNA production yield, reduces the production of unwanted heterogeneous products, or does not require additional enzymatic reactions. However, there is an urgent need to develop RNA cap analogs that enable large-scale synthesis of RNA. Furthermore, if a cap structure capable of maintaining mRNA stability in vivo, improving translation efficiency, or reducing side effects such as immunogenicity when applied as an actual RNA therapeutic agent or vaccine is provided, universal utility in the field of RNA therapeutic agent or vaccine is achieved. It could be.
