Description
本発明は、新規な硫酸化糖残基修飾オリゴ糖含有ポリウレタン誘導体およびその製造方法に関する。 The present invention relates to a novel sulfated sugar residue-modified oligosaccharide-containing polyurethane derivative and a method for producing the same.
近年、糖鎖が多様な生命現象(細胞認識や情報伝達、細胞接着、分化・増殖、ガン化、ウイルス感染、血液凝固、免疫反応など)に深く関わっていることが明らかになり、糖鎖を組み込んだ機能性材料や医薬品の開発研究が活発に行われている(例えば、非特許文献1、非特許文献2、非特許文献3)。
目的の生理機能を発現する糖鎖含有機能性材料を開発するためには、糖鎖の構造と生理活性の相関を分子や官能基レベルで研究し、糖鎖分子を自由自在に修飾したり高分子に導入する技術が求められる。
なかでも、硫酸化糖は、インフルエンザウイルス、エイズウイルス等に対する親和性を有することが知られており、この原理を利用して、ウイルスを捕捉可能な新しい材料及びその製造方法の開発が要望されている。
このような背景のもと、種々の糖鎖含有高分子が報告されてきた。例えば、硫酸化ガラクトース導入ポリアクリレート型(例えば、特許文献1)、硫酸化糖導入ポリエチレン型(例えば、特許文献2)、硫酸化グルコサミン導入ポリエチレン型(例えば、特許文献3)などが知られている。
In order to develop sugar chain-containing functional materials that express the desired physiological function, the relationship between the structure and physiological activity of sugar chains is studied at the molecular and functional group level, and sugar chains are freely modified or highly functional. Technology to be introduced into molecules is required.
Among them, sulfated sugar is known to have affinity for influenza virus, AIDS virus, etc., and development of a new material capable of capturing virus and a method for producing the same using this principle is desired. Yes.
Under such circumstances, various sugar chain-containing polymers have been reported. For example, a sulfated galactose-introduced polyacrylate type (for example, Patent Document 1), a sulfated sugar-introduced polyethylene type (for example, Patent Document 2), and a sulfated glucosamine-introduced polyethylene type (for example, Patent Document 3) are known. .
細胞認識、細胞接着などの生物学的機能は、糖細胞表面の糖鎖集合体(クラスター)とこれと相補的な糖鎖集合体との糖鎖−糖鎖相互作用により発現し、その相互作用の強さは糖密度と相関していることが知られている。上記特許文献に開示されている糖鎖高分子において、硫酸化糖鎖は、繰り返し単位あたり1個を線状にしか導入できないため、これらの高分子を用いてフィルム等を形成した場合、糖鎖クラスターにおける糖鎖密度を高めて糖鎖の生物学的機能(細胞認識、細胞接着など)を十分発現するには、高分子鎖中で、糖鎖が導入された繰り返し単位を増やす必要がある。しかし、これにより骨格高分子の本来のフィルム形成能、機械強度などが低下する恐れがある。
また、糖鎖を側鎖に導入する製造工程が保護・脱保護の操作を必要とするため煩雑で製造コストが高くなる問題点がある。
これら従来技術に対し、本発明の目的は、複数の硫酸化糖鎖が側鎖に導入された繰り返し単位を利用することで、糖鎖クラスターの密度が高められると共に、優れたフィルム形成能を有し、生体適合性、血液適合性が期待される硫酸化糖残基修飾オリゴ糖含有ポリウレタン誘導体、及びその簡便かつ安価な製造方法を提供することにある。
Biological functions such as cell recognition and cell adhesion are expressed by the sugar chain-sugar chain interaction between sugar chain aggregates (clusters) on the surface of sugar cells and complementary sugar chain aggregates. Is known to correlate with sugar density. In the sugar chain polymer disclosed in the above patent document, since one sulfated sugar chain can be introduced only linearly per repeating unit, when such a polymer is used to form a film or the like, In order to increase the sugar chain density in the cluster and fully express the biological function of the sugar chain (cell recognition, cell adhesion, etc.), it is necessary to increase the number of repeating units into which the sugar chain is introduced in the polymer chain. However, this may reduce the original film-forming ability and mechanical strength of the skeleton polymer.
In addition, since the production process for introducing a sugar chain into a side chain requires a protection / deprotection operation, there is a problem that the production cost is complicated.
In contrast to these conventional techniques, the object of the present invention is to increase the density of sugar chain clusters and to have excellent film-forming ability by using a repeating unit in which a plurality of sulfated sugar chains are introduced into the side chain. Another object of the present invention is to provide a sulfated sugar residue-modified oligosaccharide-containing polyurethane derivative expected to have biocompatibility and blood compatibility, and a simple and inexpensive production method thereof.
本発明者らは、上記問題点に鑑み鋭意検討した結果、1級水酸基を2個有するオリゴ糖、ジイソシアネートおよび必要に応じてジオール化合物の付加重合により、オリゴ糖含有ポリウレタン誘導体を得、これにジカルボン酸無水物を反応させることにより、カルボキシル基修飾オリゴ糖含有ポリウレタン誘導体を得、さらにこれをアミノ糖と反応させることで得られる糖鎖を側鎖に有する糖残基修飾オリゴ糖含有ポリウレタン誘導体を、硫酸化試薬と反応させることにより、硫酸化糖鎖を側鎖に有する糖残基修飾オリゴ糖含有ポリウレタン誘導体を得る事ができることを見出し、本発明を完成するに至った。 As a result of intensive studies in view of the above problems, the present inventors obtained an oligosaccharide-containing polyurethane derivative by addition polymerization of an oligosaccharide having two primary hydroxyl groups, a diisocyanate, and, if necessary, a diol compound, By reacting an acid anhydride, a carboxyl group-modified oligosaccharide-containing polyurethane derivative is obtained, and a sugar residue-modified oligosaccharide-containing polyurethane derivative having a sugar chain in the side chain obtained by further reacting with an amino sugar, It was found that by reacting with a sulfating reagent, a sugar derivative-modified oligosaccharide-containing polyurethane derivative having a sulfated sugar chain in the side chain can be obtained, and the present invention has been completed.
