Description

本発明は、汎用性の高い官能基を導入したクリック反応に有用なチオアミド誘導体に関する。 The present invention relates to a thioamide derivative useful for a click reaction in which a highly versatile functional group is introduced.

高い反応性・選択性を持った反応で比較的単純な小分子パーツを多様に組み合わせ、新たな機能性分子を創出する鍵反応をクリック反応と総称し、バリー・シャープレスによって提案された。 A key reaction to create new functional molecules by combining various relatively simple small molecule parts with highly reactive / selective reactions, collectively called click reactions, and was proposed by Barry Sharples.

クリック反応は、生体直交性(通常は生体分子の構造中にない官能基の組み合わせで、これらが互いに選択的に反応しかつ、そのことが他の内因性分子には影響を与えない化学的性質)を持つ代表的な反応であり、生体に緩和な条件で新たな化学結合を導入することができるため、細胞表面の生体分子を特異的に蛍光可視化する等の高度な技術に応用されている(非特許文献1)。
アミド結合形成反応としての Staudinger 反応(非特許文献2)や、アシルスルホンアミド結合形成反応としての Sulfo Click 反応(非特許文献3)なども、生体直交性を有するクリック反応の例として挙げられる。
Click reaction is a bio-orthogonal (chemical property that is a combination of functional groups that are not normally in the structure of a biomolecule, which react selectively with each other and do not affect other endogenous molecules). ) And can introduce new chemical bonds into the living body under mild conditions, so it has been applied to advanced technologies such as specific fluorescence visualization of biomolecules on the cell surface. (Non-Patent Document 1).
Staudinger reaction (Non-patent document 2) as an amide bond forming reaction and Sulfo Click reaction (Non-patent document 3) as an acylsulfonamide bond forming reaction are also examples of click reactions having bioorthogonality.

発明者らは、チオアミドとスルホニルアジドが効率よく結合を形成する新規クリック反応を開発した(非特許文献4)。この反応は、様々な溶媒中で反応が進行し、中でも水中で最も効率よい有用な反応である。
しかし、この反応に用いる市販のチオアミドの種類は少なく、また、ローソン試薬などのチオ化剤によるチオアミド化が利用できるものの汎用性の高いチオアミド誘導体が求められている。
The inventors have developed a novel click reaction in which a thioamide and a sulfonyl azide efficiently form a bond (Non-patent Document 4). This reaction proceeds in various solvents and is the most efficient and useful reaction in water.
However, there are few types of commercially available thioamides used in this reaction, and there is a demand for highly versatile thioamide derivatives although thioamidation with a thioating agent such as Lawesson's reagent can be used.

本発明のチオアミドとスルホニルアジドを基質とする緩和なクリック反応で、スルホニルアミジンが高収率で生成し、容易にアシルスルホンアミドへと変換可能である。また、クリック生成した結合の一部は、アシルスルホンアミドへの変換時に切断され、さらにアシルスルホンアミドもN−アルキル化後に切断可能である。また、生体直交性を有し、水溶液中室温で容易に反応が進行するため、生体系への応用できる。 By a mild click reaction using thioamide and sulfonyl azide of the present invention as substrates, sulfonylamidine is produced in high yield and can be easily converted to acylsulfonamide. In addition, a part of the click-generated bond is cleaved upon conversion to acylsulfonamide, and acylsulfonamide can also be cleaved after N-alkylation. Moreover, since it has bioorthogonality and the reaction proceeds easily at room temperature in an aqueous solution, it can be applied to biological systems.
