Abstract

本発明は、式(I)(式中、であり、R1a、R1b、R2〜R8、XおよびYは、それぞれ明細書における定義と同意義である)で示される化合物および該化合物を含有する医薬組成物を提供する。The present invention relates to a compound represented by the formula (I) (wherein R 1a, R 1b, R 2 to R 8, X and Y are as defined in the specification, respectively) and a medicament containing the compound A composition is provided.

Description

本発明は、オピオイドδ受容体アゴニスト作用を有する化合物、および該化合物を含有する医薬組成物に関する。   The present invention relates to a compound having an opioid δ receptor agonist activity and a pharmaceutical composition containing the compound.

モルヒナン骨格を有するモルヒネは、強力な鎮痛薬として古くから知られ、現在でも多用されているが、依存形成、呼吸抑制作用、便秘等、臨床上問題となる重篤な副作用があり、使用にあたっては厳重な管理を必要とする。   Morphine having a morphinan skeleton has long been known as a powerful analgesic and is still widely used, but there are serious side effects that cause clinical problems such as dependence formation, respiratory depression, and constipation. Strict management is required.

近年、中枢で鎮痛作用に関与する受容体としてμ、δ、κの3つのタイプのオピオイド受容体の存在が明らかにされている。モルヒネにみられるこれらの副作用はμ受容体アゴニスト特有のものであり、δ、κ受容体アゴニストには見られないことが分かっている。   In recent years, the existence of three types of opioid receptors, μ, δ, and κ, has been clarified as receptors involved in analgesic action in the center. These side effects seen in morphine are peculiar to μ receptor agonists and are not found in δ and κ receptor agonists.

モルヒネにみられる上記のような副作用を発現しない鎮痛薬を志向して、これまで数々のモルヒネ同族体が合成された。例えば、本発明の式(I)と構造的に関連する化合物として、特公昭45−25300号(特許文献1)には、4,5−エポキシ部位が除去されたインドロモルヒナン化合物が開示されており、鎮痛作用、鎮咳作用等の中枢神経抑制作用を示すことが示唆されている。しかしながら、オピオイドδ受容体に対する作用については記載されていない。一方、他の文献において、4,5−エポキシ部位が除去されたこのようなインドロモルヒナン化合物がオピオイドδ受容体に選択的に結合することが報告されているものの(非特許文献1および2)、これらの化合物は、オピオイドδ受容体に対するアンタゴニストであり、オピオイドδ受容体に対するアゴニスト活性は非常に弱い。
特公昭45−25300号公報 J. Med. Chem. 1999, 42, 1673-1679 Tetrahedoron, 56(2000)7399-7402
Many morphine congeners have been synthesized so far, aiming at analgesics that do not cause the above-mentioned side effects seen in morphine. For example, as a compound structurally related to the formula (I) of the present invention, Japanese Patent Publication No. 45-25300 (Patent Document 1) discloses an indolomorphinan compound from which a 4,5-epoxy moiety has been removed. It has been suggested that it exhibits central nerve inhibitory action such as analgesic action and antitussive action. However, no effect on the opioid δ receptor is described. On the other hand, although it has been reported in other documents that such an indolomorphinan compound from which the 4,5-epoxy moiety has been removed selectively binds to the opioid δ receptor (Non-patent Documents 1 and 2). ), These compounds are antagonists to the opioid δ receptor, and the agonist activity to the opioid δ receptor is very weak.
Japanese Patent Publication No. 45-25300 J. Med. Chem. 1999, 42, 1673-1679 Tetrahedoron, 56 (2000) 7399-7402

本発明の目的は、オピオイドδ受容体に対して強いアゴニスト活性を有する新規な化合物を提供することにある。本発明者らは、上記課題を解決するため鋭意検討した結果、式(I)に示されるモルヒナン誘導体が、強いアゴニスト活性を有し、特にオピオイドδ受容体に対して高い結合親和性を示すことを見出し、本発明を完成するに至った。   An object of the present invention is to provide a novel compound having a strong agonist activity for the opioid δ receptor. As a result of intensive studies to solve the above problems, the present inventors have found that the morphinan derivative represented by the formula (I) has a strong agonist activity, and particularly shows a high binding affinity for the opioid δ receptor. As a result, the present invention has been completed.

Test Example 1: Opioid Receptor Binding Test The binding affinity of the compounds of the present invention to μ, δ and κ opioid receptors was examined.
Experimental material μ receptor: rat cerebral membrane fraction δ receptor: rat cerebral membrane fraction κ receptor: guinea pig cerebral fraction Method: Rat according to previous report (J. Med. Chem. 1999, 42, 3527-3538) Cerebral and guinea pig cerebral membrane fractions were prepared. [ 3 H] DAMGO (μ opioid receptor), [ 3 H] DADLE (δ opioid receptor), [ 3 H] U69,593 (κ opioid receptor) were used as ligands for each opioid receptor. The μ receptor assay used rat cerebral membrane fraction. For the assay of δ receptor, 100 nM DAMGO, 3 mM MnCl 2 and 100 mM choline chloride were added using rat cerebral membrane fraction. For the assay of kappa receptor, 1 μg / ml captopril was added using a guinea pig cerebral membrane fraction. Nonspecific binding used 20 μM levalorphan for μ and δ receptors and 1 μM U69,593 for kappa receptors. As a control compound:
Figure 2008001859
The known δ opioid receptor agonist TAN-67 (for example, described in JP-A-4-275288), naltrindole for μ and δ receptors, and naloxone for κ receptors were used. Each receptor membrane fraction, ligand and sample were reacted for a predetermined time, and after B / F separation, the binding inhibition rate (IC 50 value) of the sample was calculated. The Ki value was calculated from the obtained IC 50 value using the following formula.
Ki = IC 50 / (1 + L / Kd)

試験例2:オピオイドδ受容体機能試験
オピオイドδ受容体に対する本発明化合物のアゴニスト活性を[35S]GTPγS結合試験により調べた。
実験材料:オピオイドδ受容体発現細胞膜画分
方法:オピオイドδ受容体発現細胞膜画分はPerkinElmer社より購入した。受容体膜画分および検体を0.5mLの緩衝液(50mM Tris、1mM EDTA、12.5mM MgCl2、100mM NaCl、0.5%BSA、3μM GDP、0.1nM[35S]GTPγS、pH7.4)中、所定の時間反応させ、B/F分離を行った。定常活性は、3μM GDP(アゴニスト非存在下)添加条件下にて、また非特異的結合は10μM GTPγS添加条件下にて測定した。対照アゴニストとして、TAN−67および[Met5]−エンケファリンを用いた。検体のアゴニスト活性は[Met5]−エンケファリンの活性を100%としたときの最大活性(Emax値;%)並びにEC50値で表した。実験結果を表2に示す。

Test Example 2: Opioid δ Receptor Function Test The agonist activity of the compound of the present invention against the opioid δ receptor was examined by a [ 35 S] GTPγS binding test.
Experimental material: Opioid δ receptor-expressing cell membrane fraction Method: Opioid δ receptor-expressing cell membrane fraction was purchased from PerkinElmer. Receptor membrane fraction and specimen were treated with 0.5 mL buffer (50 mM Tris, 1 mM EDTA, 12.5 mM MgCl 2 , 100 mM NaCl, 0.5% BSA, 3 μM GDP, 0.1 nM [ 35 S] GTPγS, pH 7. During 4), reaction was carried out for a predetermined time, and B / F separation was performed. Steady activity was measured under the condition of adding 3 μM GDP (in the absence of agonist), and non-specific binding was measured under the condition of adding 10 μM GTPγS. TAN-67 and [Met5] -enkephalin were used as control agonists. The agonist activity of the specimen was represented by the maximum activity (Emax value;%) and the EC 50 value when the activity of [Met5] -enkephalin was 100%. The experimental results are shown in Table 2.
Figure 2008001859

表1および表2に示すとおり、本発明の化合物は、オピオイドδ受容体に対して強いアゴニスト活性を有することがわかる。また、本発明の化合物は、オピオイドδ受容体に対して特異的な親和性を有する。特に化合物47は、対照化合物(TAN-67)と比較して、38倍もの高いアゴニスト活性を示した。   As shown in Table 1 and Table 2, it can be seen that the compounds of the present invention have a strong agonist activity for the opioid δ receptor. The compounds of the present invention also have a specific affinity for the opioid δ receptor. In particular, Compound 47 showed 38 times higher agonist activity than the control compound (TAN-67).

本発明に係る化合物は、オピオイドδ受容体に対して強いアゴニスト活性を有し、鎮痛剤として有効な医薬となり得る。   The compound according to the present invention has a strong agonist activity with respect to the opioid δ receptor, and can be a pharmaceutical effective as an analgesic.
