コンツラキン−Gの初期分析についての実験手順
1.粗毒液。 Conus geographusの被検体は、フィリピンのMarinduque Isから採取した。粗毒液は、毒液管の切開によって得、次いで凍結乾燥し、−70℃にて貯蔵した。
非グリコシル化Thr10−コンツラキン−Gおよび合成的コンツラキン−Gは、ラット・ニューロテンシン1型および2型の受容体(rNTR1およびrNTR2)ならびにマウス・ニューロテンシン3型(mNTR3)で別々にアッセイされた。[125I−Tyr3]ニューロテンシン1−13を調製して、従前に記載(Saadoulら, 1984)のごとく精製した。rNTR1(Tanakaら, 1990)および(ラット脳cDNAライブラリー(Stratagene)をスクリーニングすることによってJ Mazellaの研究室においてクローン化された)rNTR2のいずれかを発現している安定な、トランスフェクトされたCHO細胞を10%ウシ胎仔血清および0.25mg/mlG418(Sigma, France)を含有するDMEM中で増殖させた。細胞膜のホモジネートは、最初に記載された(Chabryら, 1994)ごとく調製した。蛋白質濃度は、標準品として卵白アルブミンを用いるBio−Radの手法によって測定した。
コンツラキン−Gの精製
Conus geographus毒液の画分は、マウスを過剰に不活発とさせることで検出した。通常、伏せているマウスが棒で突つかれる場合、彼らは直ちに置き上がり、相当な距離を走る。図5に示されたConus geographusからの画分のi.c.v.注射に際して、彼らが起きる前にマウスを非常に多くの力で突かなければなく、起きた後に、彼らは1または2歩歩き、直ちに、再度伏せるだろう。この「不活発な行動」に続いて数工程で精製し、見掛け上均質のペプチドをさらに分析した。このペプチドは、コンツラキン−G(フィリピン語のtulakinは、基語tulak、押すことからの「押されるか突かねばならない」を意味する)と命名された。「G」は、ペプチドがConus geographusからのものであることを示す。
精製されたコンツラキン−Gの生化学的特徴付け
精製ペプチドの試みられたアミノ酸配列分析は、該ペプチドがN末端にてブロックされることを明らかにした。大部分のN末端的がブロックされたコーヌスペプチドは、第1位にてピログルタミン酸残基を持っているので、ペプチドをピログルタミン酸アミノペプチダーゼで処理した。この結果、保持時間をシフトさせ、ピログルタミン酸残基の除去を示唆した。酵素処理後、ピログルタミン酸残基の除去を確認する標準的Edman方法によって、配列Ser-Glu-Glu-Gly-Gly-Ser-Asn-Ala-Xaa-Lys-Lys-Pro-Tyr-Ile-Leu(配列番号:4)を得、ここに、Xaaは、アミノ酸が第9サイクルにおいて(第10位にて)指定されないが、トレオニン残基についての非常に低いシグナルが観察されたことを示す。アミノ酸分析は、該ペプチドの1つのトレオニン残基の存在と一致した。
Thr 10 がO−グリコシル化される証拠
天然のコンツラキン−Gはウシの精巣から単離されたβ−ガラクトシダーゼで処理した。この酵素は、複合糖質の非還元端からの末端のβ 1→3ガラクトピラノシル残基を優先的に加水分解した。天然試料のβ−ガラクトシダーゼ処理後、新しい成分をRP−HPLCで観察した。この成分を集めて、MALD−MSで分析し、その中の種はm/z1907にて観察された。質量差およびその酵素の特異性は遊離されるべき末端のガラクトース残基と一致した。β−ガラクトシダーゼ加水分解の結果に基づいて、発明者らは、グリカン部位が糖ペプチドのコアユニットとしてセリンまたはトレオニンに結合した二糖Gal(β1→3)GalNAc(α1→)を遊離させるO−グリコシダーゼ処理に感受性であろうと推理した。天然のコンツラキン−GのO−グリコシダーゼ処理は、酵素的加水分解混合物をRP−HPLCで分析した後に、事実、新しい種を生じさせた。新しい成分を集めて、MALD−MSで分析し、m/z1704の種は、Hex-HexNAcの喪失と一致して観察された(すなわち、該質量は、第10位での非修飾トレオニン残基を持つペプチドについて予測されたものと一致した)。酵素的加水分解の結果は、Gal(β1→3)GalNAc(α1→)グリカンの存在と一致する。O−グリコシダーゼおよびβ−ガラクトシダーゼの加水分解の結果に基づき、大部分の豊富な糖ペプチドの構造は:
非グリコシル化およびグリコシル化のコンツラキン−Gの合成
16個のアミノ酸の非グリコシル化ペプチドを化学的に合成した。合成物質は、RP−HPLCに対して酵素的にデス−グリコシル化したコンツラキン−Gと同一の保持時間を有することが判明した。また、Thr10に結合したGal(β1→3)GalNAc(α1→)を含有する16個のアミノ酸のグリコシル化コンツラキン−Gを合成した。この合成グリコシル化コンツラキン−Gは、RP−HPLCで天然のコンツラキン−Gと共溶出した。天然および合成のコンツラキン−Gの双方で観察されたポスト・ソース・ディケイ断片化スペクトルは、非常に小さな断片化パターンを示した。
合成のグリコシル化および非グリコシル化のコンツラキン−Gの生物学的効力
ニューロテンシン1−13、非グリコシル化Thr10−コンツラキン−Gまたは合成コンツラキン−Gをicv投与した場合に、腸収縮、毛を口でそろえる/繕いの不存在、および尾部抑制の感受性の低下と共に、天然のコンツラキン−Gが当初に単離された運動制御の喪失が観察された徴候であった。これらの観察をより詳細に調べるために、表3に詳述したごとく、用量応答比較を行った。非グリコシル化Thr10−コンツラキン−Gアナログは、1ナノモル以上の用量にて活性であるが、300ピコモルの用量では不活性であった。対照的に、コンツラキン−Gは、30ピコモルの用量または約5ピコモル/gにて運動制御の喪失を得ることが判明した。
コンツラキン−Gアナログの生物学的活性
コンツラキン−Gのいくつかペプチドアナログの生物学的活性をマウスのicv注射による前記と同様の方法において試験した。これらのペプチドは本明細書に記載のごとく合成し、以下のアナログが含まれた:
Ser10に関して天然のグリコシル化を含むSer10−コンツラキン−G(アナログA);および
Ser10に関して天然のグリコシル化を含むΔ1−9−Ser10−コンツラキン−G(アナログB)
アナログAは天然のコンツラキン−Gよりわずかに活性であることが判明した。また、アナログBは、100ピコモルの用量にて2週齡のマウスにおいて試験した場合に、アナログAと同一の活性、すなわち、開始および回復時間を有した。この試験において、マウスは、75分間後に彼ら自身では起きることが依然としてできなかった。1ナノモルおよび300ピコモルの用量での3週齡のマウスにおける試験の場合、同一活性は、そのアナログ間に見られ、これらのマウスは、100分間眠そうであった。これらの実験は、N末端アミノ酸残基を取り除いたグリコシル化コンツラキン−Gアナログが活性を保持することを示した。同様の結果は、Thr10に天然のグリコシル化を含むかまたは含まないSer6に関して天然のグリコシル化を含むΔ1−5−Ser6−コンツラキン−Gのごとき他のアナログについて達成された。これらの結果は、切形部位の付近のグリコシル化セリン残基の置換は、活性アナログを与えることを示す。
Thr 10 −コンツラキン−Gの鎮痛活性を評価するための材料および方法
1.急性の痛み(ホットプレート)。 Thr10−コンツラキン−G(CGX−1063)またはビヒクルを5μlの用量にて脳室内(icv)を介して投与した。投与15分間後に、動物を55℃にホットプレート上に置いた。脊髄的に媒介された行動応答の最初の応答(しりごみ)に対する潜在時間、および急性の痛みに対する中枢的に総合された運動応答の最初の後肢のなめを記録した。マウスは、応答が観察されないならば、60秒後にホットプレートから取出した。ホットプレート上に置く直前に、運動機能を加速回転棒からの最初の落下までの潜在時間を測定することによって試験した。
コンツラキン−Gの鎮痛活性を評価するための材料および方法
1.急性の痛み(テイル・フリック(tail-flick))。薬物(コンツラキン−G(CGX−1160)またはThr10−コンツラキン−G(CGX−1063))または生理食塩水(saline)をHyldenおよびWilcoxの方法(HyldenおよびWilcox、1980)に従い5μlの一定容量中にて脊髄内(i.t.)投与した。マウスは、タオルに穏やかに巻き、尾部を露出した。i.t.注射後の種々の時点にて、尾部を54℃に維持した水浴中に少し浸し、次いで活発な尾部引込めまでの時間を記録した。8秒間までに尾部引込めがなかったならば、尾部を取出し、組織損傷を防止した。
にて出発して、動物を加速回転棒上に置き、最初に落下までの潜在時間を記録した。動物は、30、60、120、240および300分(または、落下までの潜在時間が対照値にもどるまで)にて再試験した。また、直腸温を同一時点にてこれらの動物において記録した。
コンツラキン−Gの鎮痛活性
CGX−1160は、テイル・フリック潜在時間(図10A)を用量依存的に増大させ、ピーク効果の時間は≦30分間であった(試験された最も早い時間、図10B)。さらに、潜在時間の増加は持続的であり、注射5時間後にて引込め時間が上昇し、注射後24時間にてベースラインに戻った(図10B)。また、CGX−1063は、CGX−1160に対して、このモデルにおいて、引込めの潜在時間に変動しやすいが、用量依存的な増加を示し、次いで、最も適度な抗痛覚効力のみを示した。対照的に、NTは、テイル・フリックアッセイにおいて引込め潜在時間を有意には上昇させなかった(図10A〜10B)。
コンツラキン−Gの抗精神病活性を評価するための材料および方法
1.材料。D−アンフェタミンは、Sigma(St. Louis、MO)から入手した。コンツラキン−G(CGX−1160;合成の16個のアミノ酸O−結合糖ペプチド)を上記のごとく合成した。
コンツラキン−Gの抗精神病活性
通過距離[F(4,21)=7.87、P<0.05]および移動に費やした時間[F(4,21)=6.17、P<0.05]の双方により測定された運動活性に対する薬物処置の有意な効果が、本試験において判明した。D−アンフェタミン投与の結果、通過距離および移動に費やした時間の双方が用量依存的に増加した(図17〜18)。コンツラキン−G(100ピコモルi.c.v.)でのマウスの前処置は、通過距離および移動に費やした時間におけるアンフェタミン刺激された(3mg/kg i.p.)増加をかなり低下させた。基礎的運動活性(通過距離および移動に費やした時間の双方)における低下は、コンツラキン−G(100ピコモル i.c.v.)での前処置後に見られたが、しかしながら、この低下は統計学的有意差には達しなかった。
コンツラキン−Gの抗痙攣活性を評価するための材料および方法
1.動物。雄性フリングス(Frings)(20〜25グラム)を12時間の明暗サイクルを持つ温度制御(23°±1℃)室にて飼育し、食餌および水を自由摂取させる。マウスは、HEW 刊行物(NIH)第8623号、「実験用動物の配慮および使用についてのガイド(Guide for the Care and Use of Laboratory Animals)」の推奨に一致する方法で飼育し、食餌させ、扱った。全マウスは、実験用動物のヒューマンケアに対するPublic Health Serviceの方針に従って安楽死させた。
コンツラキン−Gの抗痙攣活性
コンツラキン−G(CGX−1160)およびThr10−コンツラキン−G(CGX−1063)は、i.c.v.投与後にフリングス・マウスにおける聴覚性発作を強力でかつ用量依存的にブロックした(図19)。痛みモデルにおける効力と同様に、CGX−1160はCGX−1063より効力があり、ED50は、各々、7.1ピコモルおよび27.0ピコモルであった(表7)。また、従前の試験に一致して、NTは、CGX−1160または−1063より劇的に小さな効力であった。NTの用量応答曲線が依然として完成していないので、NTは1ナノモルのi.c.v.投与後の50%保護を示した。運動毒性につき試験した場合、CGX−1160は、200ピコモルまでの用量にて50%毒性レベルに達しなかったが(図19)、一方、CGX−1063のTD50は、約375ピコモルであり、その結果、試験された用量につきPIが14と見積られた。
