Description

本発明はスフィンゴ脂質の細胞内での挙動を解明するために有用な、蛍光標識基を導入したスフィンゴシン類縁体に関するものである。 The present invention relates to a sphingosine analog having a fluorescent labeling group useful for elucidating the intracellular behavior of sphingolipids.

スフィンゴミエリンの代謝物であるスフィンゴ脂質は、細胞死、細胞増殖、細胞分化、プロテインキナーゼＣ阻害など様々な生体内情報伝達に関与していることから大きな注目を集めており、スフィンゴ脂質が関係する生体現象の解明が多くの研究者により積極的に行われている。 Sphingolipid, which is a metabolite of sphingomyelin, has attracted a great deal of attention because it is involved in various in vivo signal transduction such as cell death, cell proliferation, cell differentiation, and protein kinase C inhibition. Biological phenomena have been elucidated actively by many researchers.

そのスフィンゴ脂質の１つであるスフィンゴシンは主に酵母細胞に存在するが、これは哺乳動物細胞においてシグナル分子として知られているスフィンゴシンに対応しており、多くの研究が行われている。しかしながら、スフィンゴシンの細胞内での存在場所や発現に至る経路、作用機序などの情報は充分に得られていない。 One of the sphingolipids, sphingosine, is mainly present in yeast cells. This corresponds to sphingosine known as a signal molecule in mammalian cells, and many studies have been conducted. However, information on the location of sphingosine in the cell, the route leading to its expression, the mechanism of action, etc. has not been sufficiently obtained.

現在、この代謝機構を解明するものとして、Ｃ６−ＮＢＤフィトスフィンゴシンやＣ１２−ＮＢＤフィトスフィンゴシンという化合物が市販されているが、これらは副鎖であるアシル基に蛍光標識基ユニットがあり、この部分は加水分解酵素により切断されるため、フィトスフィンゴシンが代謝されたフィトスフィンゴシン−１−リン酸の細胞内の局在場所や代謝物の挙動を解明するためには有用ではない。 At present, as a mechanism for elucidating this metabolic mechanism, compounds such as C6-NBD phytosphingosine and C12-NBD phytosphingosine are commercially available, and these have a fluorescent labeling group unit in the acyl group as a sub-chain. Since it is cleaved by the hydrolase, it is not useful for elucidating the intracellular location of phytosphingosine-1-phosphate in which phytosphingosine is metabolized and the behavior of the metabolite.

このような問題を解決するために代謝をうけない主鎖に蛍光標識基を導入した化合物も開発されている。例えば、特許文献１には、スフィンゴシン類縁体のアルキル基末端に蛍光標識基を導入した化合物が記載されている。また、特許文献２には、フィトスフィンゴシン類縁体のアルキル基末端に蛍光標識基を導入した化合物が記載されている。
特開２００３−２６１７９４号公報特開２００４−２６９３８１号公報 In order to solve such a problem, a compound in which a fluorescent labeling group is introduced into a main chain that is not metabolized has been developed. For example, Patent Document 1 describes a compound in which a fluorescent labeling group is introduced at the end of an alkyl group of a sphingosine analog. Patent Document 2 describes a compound in which a fluorescent labeling group is introduced at the end of an alkyl group of a phytosphingosine analog.
JP 2003-261794 A JP 2004-269281 A

しかしながら、特許文献１および２に記載されている化合物は細胞内でリン酸エステル部分が加水分解されるため、受容体との複合体の挙動観測が困難であるという問題を有している。 However, the compounds described in Patent Documents 1 and 2 have a problem that it is difficult to observe the behavior of the complex with the receptor because the phosphate ester moiety is hydrolyzed in the cell.

本発明は上記事情に鑑みなされたものであり、スフィンゴシンの細胞内での存在場所や代謝機構を解明するために有用な、リン酸エステル部分が加水分解されにくい蛍光標識基部位を有するスフィンゴシン類縁体を提供することを目的とするものである。 The present invention has been made in view of the above circumstances, and is useful for elucidating the location and metabolic mechanism of sphingosine in cells, and a sphingosine analog having a fluorescent labeling group site where the phosphate ester moiety is difficult to hydrolyze Is intended to provide.

本発明の蛍光標識化スフィンゴシン１−リン酸メチレン置換体は、下記一般式（Ｉ）

The fluorescently labeled sphingosine 1-methylene phosphate-substituted product of the present invention has the following general formula (I)

（式中、Ｒ^１およびＲ^２は水素原子または低級アルキル基であり、Ｑ^１およびＱ^２は水素原子またはアミノ基の保護基であり、Ｑ^３は水素原子または水酸基の保護基であり、Ｘは炭素数１〜１５のアルキレン基であり、Ｚは蛍光標識基である。Ｑ^１とＱ^２、Ｑ²とＱ^３あるいはＱ^１とＱ^３はそれぞれ一体となって環を形成していてもよい。）で表されることを特徴とするものである。 Wherein R ¹ and R ² are a hydrogen atom or a lower alkyl group, Q ¹ and Q ² are a hydrogen atom or an amino group protecting group, Q ³ is a hydrogen atom or a hydroxyl protecting group, Is an alkylene group having 1 to 15 carbon atoms and Z is a fluorescent labeling group, Q ¹ and Q ² , Q ² and Q ^3, or Q ¹ and Q ³ may be combined to form a ring. It is characterized by being expressed by

In addition, since the fluorescently labeled sphingosine 1-phosphate methylene phosphate of the present invention has a strong bond between phosphorus in the phosphate ester moiety and carbon in the main chain, and the phosphate ester moiety is not easily hydrolyzed in the cell, It is also useful for elucidating the behavior of the complex with the receptor for phytosphingosine-1-phosphate.
