    Abstract

    Mitochondrial dysfunction caused by aging leads to decreased energy metabolism, resulting in functional decline and increased frailty in multiple tissues. Strategies for protecting and activating mitochondria under stressful conditions are required to suppress aging and age-related diseases. However, it is challenging to develop drugs capable of boosting mitochondrial respiration and compensating for the reduced intracellular adenosine triphosphate (ATP) levels. In this study, we developed a prodrug that stimulates the metabolism of intracellular adenine nucleotides (AXP: adenosine monophosphate (AMP), adenosine diphosphate (ADP), and ATP). It enhances AMP-activated protein kinase activity, fatty acid oxidation, oxidative stress resistance, and mitochondrial respiration, thereby increasing the intracellular ATP levels. Furthermore, this prodrug markedly extended the lifespan ofCaenorhabditis elegans. The stimulation of the AXP energy metabolism (AXP stimulation) proposed in this study is expected to offer a new strategy against aging and pave the way for a novel approach in the bioenergetic molecules drug discovery.

    Abstract

    MicroRNAs (miRNAs) regulate gene expression through RNA interference. Consequently, miRNA inhibitors, such as anti‐miRNA oligonucleotides (AMOs), have attracted attention for treating miRNA overexpression. To achieve efficient inhibition, we developed 2‐amino‐6‐vinylpurine (AVP) nucleosides that form covalent bonds with uridine counterparts in RNA. We demonstrated that mRNA cross‐linked with AVP‐conjugated antisense oligonucleotides with AVP were protected from gene silencing by exogenous miRNA. However, endogenous miRNA function could not be inhibited in cells, probably because of slow cross‐linking kinetics. We recently developed ADpVP, an AVP derivative bearing a 7‐propynyl group – which boasts faster reaction rate than the original AVP. Here, we synthesized dADpVP – a deoxy analog of ADpVP – through a simplified synthesis protocol. Evaluation of the cross‐linking reaction revealed that the reaction kinetics of dADpVP were comparable to those of ADpVP. In addition, structural analysis of the cross‐linked adduct discovered N3 linkage against uridine. Incorporating dADpVP into two types of miRNA inhibitors revealed a marginal impact on AMO efficacy yet improved the performance of target site blockers. These results indicate the potential of cross‐linking nucleosides for indirect miRNA function inhibition.

    <title>Abstract</title>
    Unnatural base pairs (UBPs) which exhibit a selectivity against pairing with canonical nucleobases provide a powerful tool for the development of nucleic acid-based technologies. As an alternative strategy to the conventional UBP designs, which involve utility of different recognition modes at the Watson–Crick interface, we now report that the exclusive base pairing can be achieved through the spatial separation of recognition units. The design concept was demonstrated with the alkynylated purine (NPu, OPu) and pyridazine (NPz, OPz) nucleosides endowed with nucleobase-like 2-aminopyrimidine or 2-pyridone (‘pseudo-nucleobases’) on their major groove side. These alkynylated purines and pyridazines exhibited exclusive and stable pairing properties by the formation of complementary hydrogen bonds between the pseudo-nucleobases in the DNA major groove as revealed by comprehensive Tm measurements, 2D-NMR analyses, and MD simulations. Moreover, the alkynylated purine-pyridazine pairs enabled dramatic stabilization of the DNA duplex upon consecutive incorporation while maintaining a high sequence-specificity. The present study showcases the separation of the recognition interface as a promising strategy for developing new types of UBPs.

    Crosslinking reactions to nucleic acids are an effective way to prepare stable complexes formed by covalent bonding. We demonstrated that fully 2'-O-methylated (2'-OMe) RNAs having a 2-amino-6-vinylpurine (AVP) exhibited an efficient crosslinking to uracil in the target RNA. Recently, we reported the preparation of crosslinked 2'-OMe RNA duplexes using AVP and the anti-miRNA oligonucleotides (AMOs) containing crosslinked duplexes at the terminal positions. These AMOs exhibited efficient microRNA (miRNA) inhibition at very low concentrations. In this article, we describe the chemical synthesis of 2'-OMe oligonucleotides containing AVP and preparation of the AMOs bearing crosslinked 2'-OMe RNA duplexes using AVP. In addition, we describe in detail the miRNA inhibition assay using these AMOs. © 2022 Wiley Periodicals LLC.

    Selective chemical reactions of biomolecules are some of the important tools for investigations by biological studies. We have developed the selective crosslinking reactions to form covalent bonds to DNA or RNA using crosslinking oligonucleotides (CFO) bearing reactive bases. In this study, we designed the cross-linkable 4-amino-6-oxo-2-vinyltriazine derivative with an acyclic linker (acyAOVT) to react with the nucleic acids-binding protein based on our previous results. We hypothesized that the acyAOVT base would form a stable base pair with guanine by three hydrogen bonds at the positions of the vinyl group in the duplex DNA major groove, and the vinyl group can react with the nucleophilic species in the proximity, for example, the cysteine or lysine residue in the nucleic acids-binding protein. The synthesized oligonucleotides bearing the acyAOVT derivative showed a higher reactivity than that of the corresponding pyrimidine derivative without one nitrogen. The duplex containing acyAOVT-guanine (G) formed complexes with Hha1 DNMT even in the presence of 2-mercaptoethanol. We expect that our system will provide a useful tool for the molecular study of nucleic acids-binding proteins.

    薬理活性を時空間制御できる光分子操作技術は、様々な生命現象の解明や高精度な治療に有用な方法論として、近年大きな注目を集めている。しかし、生体応用可能な光化学反応はきわめて限られており、より幅広い種類の化合物の光制御を実現するためには、新規光化学反応の開発が必要不可欠である。このような背景のもと、本研究では、より幅広い種類の薬理活性化合物の光制御を可能とする、含窒素芳香環を構築可能な新たな光化学反応の開発を目的とした。
    本年度は、昨年度見出したo-ニトロベンジルオキシムエーテルを用いる新規光環化反応について、詳細な反応機構解明を試みた。本光反応には、イミニルラジカルが中間体として関与すること、および酸化過程に溶存酸素が関与するという仮説のもと、ラジカルトラップ実験と過酸化水素検出実験を行った。これらの実験結果より、反応機構を明らかにすることに成功した。汎用的な光感受性基であるo-ニトロベンジル基を用いることで、イミニルラジカルを生成できることを明らかにしたのは本研究が初めてであり、光化学的な側面からも非常に重要な知見が得られたと考えている。また、培養細胞を用いた光反応について詳細な検討を行い、光環化に伴うフェナントリジン誘導体が得られていることを確認することにも成功した。本研究で開発した新規光環化反応は、従来法では困難であった薬物分子の光制御を可能とし得ることから、ケミカルバイオロジー研究や創薬研究を加速できると期待される。

    RNA modifications are over 170 chemically-modified nucleosides found in wide range of RNA species, and there is an increasing demand for elucidating their roles in gene expression system. In this study, we attempted to create a reactive probe molecule for selective labeling of pseudouridine in RNA. In detail, we synthesized middle-sized molecules which are designed to recognize and form covalent bond with pseudouridine in RNA strand. These molecules were revealed to be capable of labeling target RNA containing pseudouridine with the aid of complementary abasic site-containing DNA strand.

    3本鎖DNAは、2本鎖DNAの主溝にもう1本のDNA鎖 (TFO) が配列特異的に結合することで形成される複合体であり、ゲノム標的技術への展開が期待される。しかし、その形成は2本鎖DNAの片方の鎖がプリン塩基 (A・G) のみで構成されるホモプリン領域に限定され、ピリミジン塩基 (T・C) が1つでも存在すると、障害部位として3本鎖DNAの安定性を顕著に低下させてしまう。このような背景のもと、申請者は、3本鎖DNA形成配列を拡張するための人工核酸の創製を目指した。
    昨年度は研究計画通り、人工核酸の構造最適化(擬シチジン誘導体の開発)ならびに遺伝子発現阻害実験の予備検討を行った。これらの結果をもとに、今年度は、擬シチジン誘導体を組み込んだTFOによる遺伝子発現阻害実験を検証した。標的遺伝子には、がん原遺伝子であるhTERTを選択した。hTERTプロモーター配列には、天然型ヌクレオシドでは認識できないCG障害部位が4ヵ所存在する。予備検討として、このhTERTプロモーター配列に対するTFOを設計し、3本鎖形成能を評価したところ、CG塩基対に対応する箇所にTを組み込んだTFOが3本鎖DNAを形成できないのに対し、擬シチジン誘導体を組み込んだTFOが高い親和性をもって3本鎖を形成することを確認した。そこで、これらのTFOをHela細胞にトランスフェクションし、hTERT遺伝子の転写阻害効果を検証した。その結果、擬シチジン誘導体を組み込んだTFOは、hTERT遺伝子のmRNA発現量を有意に減少させることを確認した。
    以上の内容は、3本鎖形成配列を拡張した点、またTFOによる転写阻害効果を実証した点において、擬シチジン誘導体がゲノム標的技術の拡張に貢献できることを示す意義ある結果と考えられる。今後、本研究で開発された人工核酸が、医療やバイオテクノロジーへと展開されることを期待する。
