Description
本発明は、コンホメーションが拘束された副甲状腺ホルモン(PTH)類似体、ならびに該PTH類似体を製造および使用する方法に関する。
副甲状腺ホルモン
副甲状腺ホルモン(PTH)は84個のアミノ酸のペプチドであり、人体におけるイオン化された血中カルシウムの主要なレギュレーターである(Kronenberg, H. M., et al., In Handbook of Experimental Pharmacology, Mundy, G.R. , and Martin, T.J., (eds), pp. 185-201, Springer-Verlag, Heidelberg (1993))。胃腸系、骨格系、神経系、神経筋系および心血管の正常な機能にはカルシウム濃度の調節が不可欠である。PTHの合成および放出は主として血清カルシウムレベルによって制御され、低レベルであればホルモンの合成と放出の双方が刺激され、高レベルであれば抑制される。そして、PTHは、消化管、骨および腎臓という3つのカルシウム交換部位においてカルシウムの血中流入を直接的または間接的に促進することによって、血清のカルシウムレベルを維持する。PTHは、腎臓での活性型ビタミンDの合成を有利にすることにより、カルシウムの正味の胃腸管吸収に寄与する。PTHは、骨を再吸収する細胞である破骨細胞の分化を刺激することにより、骨からのカルシウムの再吸収を間接的に促進する。また、これは、尿細管のカルシウム再吸収の刺激、リン酸塩クリアランスの増進および活性型ビタミンDの合成を完了させる酵素の増強促進という、腎臓に対する少なくとも3つの主な作用をも媒介する。PTHは、主として、受容体を媒介とするアデニル酸シクラーゼおよび/またはホスホリパーゼCの活性化により、これらの作用を発揮するものと考えられている。
骨粗鬆症は、高齢者人口のかなりの部分、妊婦、さらに若年層にさえ見られる、肢体が不自由になる可能性のある骨格系疾患である。骨粗鬆症とは異種の疾患群をさす。臨床的には、骨粗鬆症はI型とII型に分かれる。I型骨粗鬆症は主として中年の女性において起こり、更年期のエストロゲン低下と関連しており、II型骨粗鬆症は加齢と関連している。骨粗鬆症患者にとっては、骨折修復を促進するためにデザインされた新規な治療法、または疾病に関連する骨折を予防もしくは軽減するためにデザインされた治療法が有用であると考えられる。
PTH誘導体としては、完全長分子に対してアミノ酸置換を有するか、または末端切断型であるポリペプチドが挙げられる。PTHの14アミノ酸および34アミノ酸の両アミノ末端切断型、ならびにC末端切断型が研究されている。さらに、これらの末端切断型ポリペプチド内のアミノ酸置換も検討されている。
アミノ酸配列:本願のアミノ酸配列には、アミノ酸の一文字または三文字のいずれかの表記を用いる。これらの表記法は当業者に周知ものであり、例えばCooper, G.M., The Cell 1997, ASM Press, Washington, D.C.またはAusubel et al., Current Protocols in Molecular Biology, 1994などの容易に利用できる多くの参考文献において見出すことができる。例えば、Ser−3→Alaまたは[Ala3]ペプチドなどのように配列における置換が言及されている場合、そのポリペプチドのN末端から3番目のセリンが別のアミノ酸、この場合にはアラニンで置換されていることを意味する。
α−アミノイソ酪酸(Aib)を短いN末端PTHペプチド類似体へ導入した。種々の極性または非極性溶媒でPTH(1−34)類似体のNMR研究を何度も行ったところ、ほぼSer−17からVal−31まで伸びる安定なC末端ヘリックス、およびSer−3からLys−13まで様々な伸びを示す、より短く、安定度の低いアミノ末端ヘリックスの2つのドメインの二次構造が示され、この2つのドメインは屈曲または折り返し領域によって連結されていた(Marx, U.C., et al., Biochem. Biophys. Res. Commun. 267:213-220 (2000); Chen, Z., et al., Biochemistry 39:12766-12777 (2000); Marx, U.C., et al., J. Biol. Chem. 270:15194-15202 (1995); Marx, U.C., et al., J. Biol. Chem. 273:4308-4316 (1998); Pellegrini, M., et al., Biochemistry 37:12737-12743 (1998); Gronwald, W., etal., Biol. Chem. Hoppe Seyler 377:175-186 (1996); Barden, J.A., and Kemp, B.E., Biochemistry 32:7126-7132 (1993))。最近のPTH(1−34)の結晶学的研究では、Ser−3からHis−32まで伸び、中間部にわずか15°の屈曲しか含まない連続したαヘリックスが示されている。しかし、NMRデータからは、このN末端αヘリックスが比較的弱いことが示されている。Aib残基の導入など、ヘリックスを安定化する修飾により、ペプチド特性という点で著しい利点が得られ、PTH(1−34)に匹敵する活性を有する短いペプチド(≦14アミノ酸)が得られる。
本発明による化合物またはその誘導体は、多数の用途を有する。これらには、とりわけ、PTH受容体のアゴニストまたはアンタゴニスト、骨量の減少によって顕現する種々の哺乳動物の病態の予防および治療、診断プローブ、診断プローブとして用いるための抗体を調製するための抗原、および分子量マーカーとしての使用がある。PTHポリペプチドの1以上のアミノ酸を特異的に置換することができれば、特定の分子量のポリペプチドを構築することができる。
ホルモン作用の発現における重要な工程は、ホルモンと標的細胞の原形質膜表面上の受容体との相互作用である。ホルモン−受容体複合体が形成されることにより、細胞に細胞外シグナルが伝達され、種々の生体応答が誘起される。
高カルシウム血症および低カルシウム血症のいくつかの形態は、PTHおよびPTHrPとPTH−1受容体との相互作用に関連している。高カルシウム血症は血清カルシウムレベルの異常な上昇がみられる病態であり、これは多くの場合、上皮小体機能亢進症、骨粗鬆症、乳癌、肺癌および前立腺癌、頭頸部および食道の類表皮癌、多発性黒色腫および副腎腫をはじめとするその他の疾病と関連する。低カルシウム血症は血清カルシウムレベルが異常に低い病態で、例えば甲状腺手術後の有効なPTHの欠損に起因するものである。
足場ペプチドに[M]PTH(1−14)の各位置にそれぞれAib置換を導入する効果(Shimizu, M., et al., Endocrinology (2001)(In Press))を分析した。HKRK−B28細胞におけるcAMP刺激アッセイでは、親ペプチド[M]PTH(1−14)PTH(1−34)によって誘導された細胞内cAMPにおいてほぼ同じ(〜70倍)最大(Emax)増加を刺激したが、より短いペプチドの能力(EC50)はPTH(1−34)のもの(それぞれEC50=100±20および2.5±0.4nM)(図1および表1)よりも40倍低かった。ほとんどのAib置換は能力を低下させた。6番、8番および9番の位置でのAib置換ではいくらかの低下が見られ(総て>2,300倍)2番、4番、5番および11番の位置での置換では中程度の低下が見られ(総て170〜670倍)、7番、10番、12番、13番および14番の位置での置換では小さな低下が見られた(総て<3倍;表1)。1番および3番の位置のAibの置換の結果、「M」PTH(1−14)に対してそれぞれ10倍および8倍の効力を有するペプチドが得られた(P≦0.01)。これらのAibスキャンデータは従前のアラニンスキャンおよびPTH(1−14)類似体の置換分析を拡張し、ここでは残基3を除く(1−9)領域の残基が置換に耐えられないことがわかり、残基3および10〜14は比較的耐性であることがわかった(Luck, M.D., et al., Molecular Endocrinology 13:670-680 (1999); Shimizu, M., et al., J. Biol. Chem. 275:19456-19460 (2000); Pellegrini, M., et al., J. Biol. Chem. 273:10420-10427 (1998))。
1番および3番の位置におけるAib置換の活性増強作用が受容体の膜近傍(J)領域によって媒介された可能性を、P1R−delNtで一次トランスフェクトしたCOS−7細胞で検討した。P1R−delNtは、アミノ末端細胞外ドメインの大部分を欠いた末端切断型P1Rである。この受容体構築物を用いた場合、PTH(1−34)は、P1R−WTを用いる場合よりもはるかに弱いアゴニストであったが、その他のPTH(1−14)類似体は、P1R−delNtを用いてもP1R−WTを用いる場合とほぼ同等の能力を示した(Kaul, R. , and Balaram, P., Bioorganic & Medicinal Chemistry 7:105-117 (1999))。このことに一致して、P1R−delNtに対する[Aib1,3,M]PTH(1−14)のcAMPシグナル伝達能(EC50=0.73±0.16nM)はP1R−WTを発現するCOS−7細胞に対するその能力(1.2±0.6nM)に匹敵するものであった(表2)。P1RdelNtに対して、[Aib1,3,M]PTH(1−14)は[M]PTH(1−14)(EC50=40±2nM,図3Aおよび表2)の場合よりも55倍能力が高かった。この結果は、Aib−1,3置換の能力増強作用が受容体のJドメインを介して発揮されたことを示唆するものであった。特に、[Aib1,3,M]PTH(1−14)は、PTH(1−34)がP1R−WTに対して発揮したものと同等の能力をP1R−delNtに対して発揮し(それぞれEC50=0.73±0.16nMおよび1.4±0.7nM,P=0.4,表2)、[Aib1,3,M]PTH(1−14)がP1R−delNtに対して誘導したEMaxは、PTH(1−34)がP1R−WTに対して誘導したものとほぼ等しかった(それぞれ250±20ピコモル/ウェルおよび240±50ピコモル/ウェル,P=0.7,表2)。予想されたように、PTH(1−34)はP1R−delNtに対してP1R−WTに対するよりも〜500倍弱かった(それぞれEC50=680±110nMおよび1.4±0.7nM;図3Aおよび表2)。
骨および腎臓におけるPTH標的細胞の表面で発現されるPTH−1受容体の数は明らかではないが、HKRK−B28細胞で見られるものよりかなり少ないものと思われる。従って、Aibを埋め込んだPTH類似体のいくつかはSaOS−2細胞を用いて評価した。これらの細胞はヒト骨肉腫由来であり、骨芽細胞様の特性を示し、比較的低レベルのPTH−1受容体(〜20,000受容体/細胞)を内在発現する(Marx, U.C., et al, J. Biol. Chem. 273:4308-4316 (1998))。これらの細胞では、[Aib1,M]PTH(1−14)および[Aib3,M]PTH(1−14)は、cAMP形成の刺激において、[M]PTH(1−14)の場合よりも15倍および8倍能力が高く、[Aib1,3,M]PTH(1−14)は、[M]PTH(1−14)よりも130倍能力が高かった(図4および表3)。このように、SaOS−2細胞では、[Aib1,3,M]PTH(1−14)はPTH(1−34)よりも13倍低い能力しかなく、10μMの用量でも活性が検出できなかった天然型PTH(1−14)よりは少なくとも5オーダー高い能力であった(図4)。
円偏光二色性(CD)分光法を利用して、ペプチドが液相に遊離している場合にペプチドの二次構造に対してAIb置換がおよぼす作用を分析した。サンプルは、リン酸水溶液バッファー、およびTHPペプチド断片を含むオリゴペプチドでヘリックス構造を促進する(Pellegrini, M., et al., J. Biol. Chem. 273:10420-10427 (1998); Gronwald, W., et al., Biol. Chem. Hoppe Seyler 377:175-186 (1996); Barden, J.A., and Kemp, B.E., Biochemistry 32:7126-7132 (1993))有機溶媒2,2,2−トリフルオロエタノールを含有するリン酸バッファーの両者において分析した。リン酸バッファーでは、各ペプチドのヘリックス含量は、222nMで見られる楕円性から見積もったところ、小さいものであった(≦16%)が、[Aib1,3,M]PTH(1−14)は[M]PTH(1−14)のほぼ2倍のヘッリクスを含み(それぞれ16%および8.1%)、[Aib1,3,M]PTH(1−11)もまた、[M]PTH(1−11)のほぼ2倍のヘッリクスを含んでいた(それぞれ13%および7.5%,表4)。2,2,2−トリフルオロエタノールでは、各ペプチドのヘリックス含量は増加し、[Aib1,3,M]PTH(1−14)および[Aib1,3,M]PTH(1−11)はいずれも最高レベルのヘリックス含量を示し(それぞれ56%および57%)、各々それらのAla−1,3を含有する、対応するペプチドよりもヘリックスが多かった(図6および表4)。これら2つのペプチドの高いヘリックス含量は、192nMおよび222nMの負の楕円率から明らかなだけでなく、192nMの正の楕円率からも明らかであった(図6)。非修飾型PTH(1−11)は最低量のヘリックス構造(30%)を示したが、[Aib1,3,M]PTH(1−10)は約47%のヘリックスであった(図6および表4)。これらの結果は、Aib−1,3修飾が遊離の液相でN末端PTHオリゴペプチドのヘリックス構造を増加させることを示唆している。
第一の工程としては、[M]PTH(1−14)の各位置にAibを導入した。Aibスキャンデータは、ほとんどの位置での置換が活性を低下させることを示した。しかし、Aibスキャンデータにより、1番および3番の位置に置換を有する場合にcAMPシグナル伝達能が著しく向上する(8〜10倍)ことが明らかになり、HKRK−B28細胞においてEC50が〜1nMである[Aib1,3,M]PTH(1−14)が[M]PTH(1−14)よりも100倍能力が高く、PTH(1−34)と少なくとも同等の能力であることから、これらの作用は相加的なものであった。
本発明者らは、PTH(1−34)における1番および3番の位置のAib置換([Tyr34]hPTH(1−34)アミド)が、COS−7細胞で発現されるP1R−delNtに対するcAMP刺激能を、非修飾PTH(1−34)に比べて〜100倍高めることを見出した(表5および図7B参照)。Aib置換は、COS−7細胞において完全な野生型PTH−1受容体に対するPTH(1−34)の能力を検出可能には向上させず(表5および図7A)、この結果は、極めて高レベルの完全な受容体を発現するこれらの細胞における天然型PTH(1−34)によって媒介される、すでに最大の応答によるものでありうる。受容体のほとんど全部のアミノ末端細胞外ドメインが欠失しているdelNT受容体を伴うもの、またはおそらくは低レベルの内因性PTH受容体を発現する動物の骨細胞における場合など、感受性の低い細胞系では、PTH(1−34)の能力に対するAib−1,3置換の効果は著しい。その他、上記の修飾(例えば、Gln10,ホモArg11,Ala12,Trp14,Arg19)を伴ったペプチドも同様に、hP1R−delNtを発現するCOS−7細胞において、PTH(1−34)よりもはるかに高い能力を有する。例えば、[Aib1,3,Gln10,Har11,Ala12, Trp14, Arg19, Tyr34]hPHT(1−34)のP1R−delNtに対するEC50値は1.9±0.6nMである。上記の修飾はまた感受性の低いその他の天然骨細胞系でもPTH(1−34)よりもはるかに能力が高くなる。
