Description

【0001】
【産業上の利用分野】
本発明は抗腫瘍作用を有する新規タキソール誘導体に関するものである。
【0002】
【従来の技術】
タキソールは次の化学構造式で表される天然物で、西洋イチイの幹などから微量得られる。
【0003】
【化11】

Figure 0003784945
タキソールは抗腫瘍活性を有することが知られており、その作用機作は細胞分裂における微小管の解重合阻害作用に基づくものとされており、従来の抗腫瘍剤とは異なるタイプの抗腫瘍剤としてその臨床応用が期待されている。
【0004】
これまでは、タキソールは天然から極く微量しか得られなかった。しかし、近年になって、イチイ類の葉等から比較的多量に得ることのできるタキソール前駆体である10−O−デアセチルバッカチン III
【0005】
【化12】
Figure 0003784945
を原料として用いて半合成したタキソール誘導体が報告され始めている(特開平03−505725号公報参照)。なかでも下記の構造を有する化合物(タキソテール)は、タキソールと同等以上の抗腫瘍活性を有する化合物として注目され、現在抗腫瘍剤としての開発が進められている。
【0006】
【化13】
Figure 0003784945
【0007】
【発明が解決しようとする課題】
このようにタキソールやタキソテールで表される誘導体は抗腫瘍剤として有望なものである。しかしながら、臨床試験で消化器癌、特に大腸癌等に対する有効性は低いことが判明し、より強い抗腫瘍効果を持つ誘導体が望まれている。
【0008】
【課題を解決するための手段】
従来、タキソール誘導体の10位置換基としては、アセトキシ基や水酸基、およびその水酸基をさらにアシル基、アルキルアミノカルボニル基(EP524093)等で置換したものが報告されており、また10位が水素原子置換となった誘導体(Tetrahedron Lett.,34,4921(1993))も知られている。本発明者等は鋭意検討した結果、10位にアルキル基または置換基を有するアルキル基を導入した誘導体が強い抗腫瘍活性を有することを見いだし本発明を完成した。

まず、式(1)で表わされる化合物(以下、化合物(1)と表わし、その他の番号で表わされる化合物も同様に表わす。)とアクロレインを溶媒中、ラジカル開始剤の存在下に、水素化トリス(トリメチルシリル)シラン、水素化トリブチルスズあるいは水素化トリフェニルスズを加え、化合物(2)を得る。
【0103】
この反応で用いる溶媒は、反応に不活性な溶媒であればよく、例えば、トルエン、ベンゼン、ジオキサンが挙げられる。
【0104】
反応で用いるラジカル開始剤としては、例えば、2’,2’−アゾビス(イソブチロニトリル)、過酸化ベンゾイル、2、2、6、6−テトラメチル−1−ピペラジニルオキシ フリーラジカル等が挙げられ、ラジカル開始剤の使用量は、触媒量で良い。
【0105】
反応温度は、通常50℃から150℃の範囲で行なえばよく、攪拌して行なうのが好ましい。
【0106】
アクロレインは、化合物(1)に対して5から50当量用い、水素化トリス(トリメチルシリル)シラン等は、化合物(1)に対して2から10当量程度用いる。
【0107】
こうして得られた10位が2−ホルミルエチル基である化合物(2)から10位がR61である化合物(3)への変換は、通常の有機化学的方法によって行えば良い。
【0108】
例えば、ホルミルエチル基のホルミル基を、二級アミンと還元条件下で反応させることにより三級アミンの結合したプロピオニル基に変換できる。
【0109】
また、ホルミル基を水素化ホウ素ナトリウム等で還元することにより、アルコール型の水酸基に変換できる。
【0110】
61がアルコール型の水酸基となったものは、アシルオキシ基、アルコキシル基、アミノ基、アルキルアミノ基、アルキルチオ基、フェニルゼレノ基等に変換できる。
【0111】
さらに、R61がアミノ基となったものは、アシルアミノ基、アルコキシルカルボニルアミノ基、アルキルアミノ基に変換できる。
【0112】
また、R61がフェニルゼレノ基となったものは、酸化反応によりオレフィン型の置換基に変換でき、変換されたオレフィン型の置換基は、酸化反応によりジオール型に変換でき、また酸化的開裂反応によって炭素原子数の減った置換基、例えば、ホルミルメチル基、カルボキシルメチル基に変換することもできる。
【0113】
なお、R61がホルミルメチル基となった場合、ホルミルエチル基のホルミル基と同様に変換が可能であり、例えば二級アミンと還元条件下で反応させることにより三級アミンの結合したエチル基に変換できる。

【0117】
得られた化合物(3)の各置換基を必要に応じて変換、脱保護して、化合物(4)を得ることができる。例えば、2位のベンゾイル基をCOR1 に、4位のアセチル基をCOR2 に、7位のR41をR3 またはR5 と一緒にし環構造を形成させる等の変換を行い種々の置換基を有する化合物(4)を得ることができる。
【0118】
目的化合物(I)は、化合物(3)あるいは化合物(4)を化合物(A)と反応させ、最後に保護基の除去、必要ならR61をR6 に、Z11、Z21、Z31およびZ41をそれぞれZ1 、Z2 、Z3 およびZ4 に変換することにより得ることができる。
【0119】
これらの変換および脱保護は、通常の有機化学的方法を用いて行なうことができるが、以下に例を挙げる。
【0120】
2位のベンゾイル基をCOR1 に変換する方法としては、例えば、文献(Tetrahedron Lett., 35, 8931(1994))記載の方法に従って2位のベンゾイル基を選択的に加水分解した後、アシル化する方法があり、R1 がフェニル基以外の化合物を得ることができる。
【0121】
4位のアセチル基をCOR2 に変換する方法としては、例えば、文献(J. Med. Chem.,38, 2263 (1995) )記載の方法に従って4位のアセチル基を選択的に加水分解した後、アシル化する方法があり、R2 がメチル基以外の化合物を得ることができる。
【0122】
6位のR3 、7位のR4 、8位のR5 の変換はR3 、R4 およびR5 のタイプにより種々の方法がある。
【0123】
例えば、R3 、R4 が水素原子であり6位と7位の結合が、二重結合である化合物(4)を得るには、まず、R41の保護基を除去し、7位が水酸基である化合物にした後、7位の水酸基を、例えば、メチレンクロリド中、トルフルオロメタンスルフォン酸無水物を反応させることにより、トリフルオロメタンスルフォニル化し、次いでベンゼン、テトラヒドロフランなどの溶媒中、1,8−ジアザビシクロ[5,4,0]−7−ウンデセン等で処理することにより得ることができる。
【0124】
変換された6、7位のオレフィン型置換基は、メタクロロ過安息香酸などを用いた酸化反応によりエポキシ型に変換できる。
【0125】
またエポキシ型の置換基の場合、さらに様々な変換反応が可能であり、たとえばアジ化ナトリウムなどを用いた開環反応によってR3 あるいはR4 のどちらか一方が水酸基であり、もう一方がアジド基である化合物(4)を得ることも可能である。
【0126】
4 およびR5 が一緒になって3員環を形成した構造となった化合物(4)を得るには、R41の保護基を除去し7位を水酸基にした後、この水酸基をトリフルオロメタンスルホニル化し、次いで溶媒中(アセトニトリル、テトラヒドロフラン、エチレンジクロリド等、またはこれらの混合溶媒中)でシリカゲルで処理することにより得ることができる。
【0127】
4 がフッ素原子である化合物(4)を得るには、7位が水酸基である化合物を溶媒中(テトラヒドロフラン、メチレンクロリド、エチルエーテル、トルエン、1,1,−ジメトキシエタン等、またはこれらの混合溶媒中)でジエチルアミノスルファートトリフルオライドで処理することにより得ることができる。
【0128】
4 がメトキシ基である化合物(4)を得るには、化合物(3)のR41の保護基を除去し、7位が水酸基である化合物を合成した後、ジメチルスルホキシドを溶媒として用い、無水酢酸を作用させメチルチオメチル化した後、アルコール系溶媒中、ラネーニッケルにより脱硫することにより得ることができる。
【0129】
得られた化合物(3)または(4)から、化合物(I)を得るには、まず化合物(3)または化合物(4)の13位の置換基R13が保護基で保護されている場合は、脱保護し13位が水酸基である化合物とした後、化合物(A)とナトリウムヘキサメチルジシラジドやリチウムヘキサメチルジシラジド等の塩基を用い縮合させ、最後に各置換基の変換や脱保護を実施すればよい。
【0130】

[Industrial application fields]
The present invention relates to a novel taxol derivative having antitumor activity.
[0002]
[Prior art]
Taxol is a natural product represented by the following chemical structural formula, and is obtained in trace amounts from the trunk of the yew.
[0003]
Embedded image
Figure 0003784945
Taxol is known to have antitumor activity and its mechanism of action is based on the depolymerization inhibitory action of microtubules in cell division, and is a different type of antitumor agent from conventional antitumor agents Its clinical application is expected.
[0004]
Until now, only a very small amount of taxol was obtained from nature. However, in recent years, 10-O-deacetylbaccatin III, which is a taxol precursor that can be obtained in relatively large amounts from the leaves of yews, etc.

A taxol derivative semi-synthesized using as a raw material has begun to be reported (see JP-A-03-505725). Among them, a compound having the following structure (taxotere) has been attracting attention as a compound having an antitumor activity equivalent to or higher than taxol, and is currently being developed as an antitumor agent.

[0007]
[Problems to be solved by the invention]
Thus, derivatives represented by taxol and taxotere are promising as antitumor agents. However, clinical trials have proved to be less effective for digestive organ cancer, particularly colon cancer, and a derivative having a stronger antitumor effect is desired.
[0008]
[Means for Solving the Problems]
Conventionally, as a substituent at the 10-position of a taxol derivative, an acetoxy group, a hydroxyl group, and those obtained by further substituting the hydroxyl group with an acyl group, an alkylaminocarbonyl group (EP 524093), etc. have been reported. Derivatives (Tetrahedron Lett.,344921 (1993)) is also known. As a result of intensive studies, the present inventors have found that a derivative into which an alkyl group having a substituent or a substituent is introduced at the 10-position has a strong antitumor activity and completed the present invention.

Step 5: 10-allyl-10-deacetoxy-4-deacetyl-4-O-propionyl-7-O-triethylsilylbaccatin III
1.15 g of the compound obtained in the above Step 4 was dissolved in 20 ml of tetrahydrofuran, 243 mg of metachloroperbenzoic acid was added under ice cooling, and the mixture was returned to room temperature and stirred for 1 hour. A saturated aqueous sodium bicarbonate solution was added, and the mixture was extracted with ethyl acetate and washed with saturated brine. After drying over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (elution solvent; chloroform: acetone = 50: 1 (v / v)) to obtain 615 mg of the title compound as a pale yellow amorphous solid.
