本明細書に記載されるすべてのソマトスタチンアゴニストでは、各アミノ酸残基が−NH−C(R)H−CO−の構造を表すことに留意すること。ここで、Rは側鎖(例えば、AlaではCH3)である。アミノ酸残基間の線は、アミノ酸を結合するペプチド結合を表す。また、アミノ酸残基が光学的に活性である場合、D型がはっきり明示されなければ、意図されているのはL型配置である。ジスルフィド結合(例えば、ジスルフィド架橋)がCys残基の2つのフリーチオールの間に存在するが、それは示されない。
ソマトスタチンアゴニストを合成する方法は十分に文書化されていて、当業者の能力の範囲内にある。例えば、上記に記載されるH−D−Phe−Phe−Phe−D−Trp−Lys−Thr−Phe−Thr−NH2の合成は、ヨーロッパ特許出願 0 395 417 A1号の実施例1に説明されるプロトコールに従うことによって達成することが可能である。置換N末端を有するソマトスタチンアゴニストの合成は、例えば、WO88/02756号、ヨーロッパ特許出願第0 329 295号、及びPCT公報第WO94/04752号に説明されるプロトコールに従うことによって達成することが可能である。
ヒトSSTR−1、SSTR−2、SSTR−3、SSTR−4、及びSSTR−5のcDNAクローンはすでに記載されていて(SSTR−1とSSTR−2は、Yamada, Y., et al., Proc. Natl. Acad. Sci. USA., 89: 251-255 (1992) において;SSTR−3は、Yamada, et al., Mol. Endocrinol. 6: 2136-2142 (1993) において;そして、SSTR−4とSSTR−5は、Yamada, et al., Biochem. Biophys. Res. Commun. 195: 844-852 (1993) において)、アメリカン・タイプ・カルチャー・コレクション(ATCC,ロックヴィル、メリーランド州)からも入手可能である(ATCC番号79044(SSTR−1)、79046(SSTR−2)、及び79048(SSTR−3))。制限エンドヌクレアーゼマップに基づいて、各SSTR cDNAのコーディング領域全体を、好適な制限エンドヌクレアーゼ消化により切断することが可能である(Maniatis, T., et al., 「分子クローニング−実験マニュアル」、CSHL、1982年)。制限エンドヌクレアーゼは、ニューイングランド・バイオラブズ(ベヴァリー、マサチューセッツ州)から入手可能である。このcDNAフラグメントを、分子生物学の標準技術を使用して(例えば、Maniatis, T., et al., 「分子クローニング−実験マニュアル」、コールドスプリングハーバーラボラトリー(1982年)を参照のこと)、哺乳動物発現ベクターのpCMV(Russell, D., et al., J. Biol. Chem., 264: 8222-8229 (1989))へ挿入し、発現プラスミド、pCMV−ヒトSSTR−1〜pCMV−ヒトSSTR−5を産生した。他の哺乳動物発現ベクターには、pcDNA1/Amp(インビトロゲン、サンドレジィ、カリフォルニア州)が含まれる。この発現プラスミドを好適な細菌宿主、大腸菌HB101(ストラタジーン、ラジョラ、カリフォルニア州)へ導入し、トランスフェクション用のプラスミドDNAを塩化セシウム勾配上で調製した。
内皮細胞に対する抗増殖効果とソマトスタチン類似体により引き起こされる内皮細胞の増殖及び毛細血管形成の阻害について検討するために、2つの異なるヒト in vivo モデルを実施した。これらのモデルは、二次元内皮細胞層と、in vivo での毛細血管発生を模倣する細胞外マトリックスにおける三次元内皮細胞増殖に対する、ソマトスタチン類似体の効果の研究を可能にした。さらに、これらのアッセイは、抗血管新生療法への可能な慢性臨床アプローチに類似し、ヒト組織に対する非常に長い期間の処置(それぞれ、72時間と28日)を可能にした。
材料
組換えヒト表皮増殖因子(EGF)と組換えヒト血管内皮増殖因子(VEGF)はPeproTechEC社(ロンドン、イギリス)からのものであった。EGFとVEGFは、データシートの情報に従って、滅菌蒸留水で100μg/mlの濃度に復元した。
Ades, et al., (Journal of Investigative Dermatology 1992, 99: 683-690) により特徴づけられた不死化ヒト微小血管内皮細胞系、HMEC−1を、10%熱不活性化ウシ胎仔血清(FBS)、ペニシリン(50IU/mL)、及びヒドロコーチゾン(100μg/ml)を補充した199培地において維持した。75cm2ゼラチンコート化組織培養フラスコにおいて細胞を通常通りに培養し、5% CO2、37℃の加湿空気中に保った。すべての実験で、細胞が長い増殖期にあって、上記の培養条件下で維持されているときに、0.25%トリプシン−0.03% EDTAの溶液とともに細胞を採取した。
96穴ゼラチンコート化無菌プラスチックプレートにおいてプレート培養し、一晩付着させたHEMC−1細胞の単一細胞懸濁液(5x103細胞/ウェル)について、in vitro 化学感受性試験を実施した。処置プロトコール(図1)は、24時間後、10-10〜10-6Mのソマトスタチン−14、ソマトスタチン類似体、SU5416 10-6M+VEGF 10ng/mLを陽性対照又は担体として加え、プレートを72時間インキュベートするように設計した(より詳細については、図1を参照のこと)。この処置は、各ペプチドが少なくとも9つのウェルにより表されるように計画された。実験の終了時に、細胞をリン酸緩衝化生理食塩水(PBS)で濯ぎ、トリプシン/EDTAとともに採取し、血球計で計数した。対照に対する細胞増殖の比として結果を表し、これは、3回繰り返した3回の個別実験の平均±S.E.である。
以下に記載のヒト胎盤外植片の実験モデルの使用は、ピサ大学病院倫理委員会により承認を得た(プロトコール番号005567)。
本研究には、Bocci et al., (Cancer Chemotherapy Pharmacology 1999, 43: 205-212)に記載の画像分析法を採用した。簡潔に言うと、カラービデオカメラTK−1280E(JVC、東京、日本)とマイクロコンピュータ・プロセッサーを使用して、胎盤フラグメントアッセイから得た写真を512x512ピクセルのマトリックスにおいてディジタル化した。ディジタル化した臨床像を高解像カラーディスプレイで可視化した。双方向操作、画像の定量化、及びデータ収集のために、真色画像分析ソフトウェア・パッケージ、KS300 v.1.2(コントロン・エレクトロニック社、エキング、ドイツ)を実行した。既知の寸法のサンプルで幾何較正を設定し、グレイスケール分析を実施して0〜225の範囲にある画像の密度を測定したが、ここで、0は黒(血管発芽の存在)であり、225は白(血管発芽の非存在)である。胎盤血管外植片のフィブリン培養において、発芽領域の平均グレイレベルを測定し、発芽インデックス(SI)を:
発芽インデックス=((発芽領域/発芽領域の平均グレイレベル)/外植片の周辺長さ)x100
と定義した。発芽インデックス±S.E.の対照に対する比率として結果を表す。
細胞毒性アッセイ
表Iにすべての結果を示す。ソマトスタチン類似体は、試験した濃度で、いずれも不死化ヒト微小血管内皮HMEC−1細胞に対して抗増殖活性を示し、10-7〜10-8Mで最大の効果であった。特異的なVEGF受容体阻害剤である陽性対照のSU5416(10-6M)は、56.2%の細胞増殖阻止をもたらした。
フィブリンマトリックスの内部で発芽する外植片を、胎盤フラグメントの周囲にある数多くの微小血管により特徴づけた。血管細胞は放射状に組織化し、連続した再構築を行う微小血管を形成した(図3)。この三次元微小血管ネットワークの最大成長が起きたのは第三〜第四週の間であり、外植後27日目でプラトーに達した。組織学的には、フィブリンゲル中に、フォン・ウィルブラント因子のために免疫反応する(図4)、内皮細胞のかすかな骨組みを観察した(図5)。ほとんどの実験例において、微小血管は最初の管腔を示したが、管腔がなくて内皮細胞しか観察されない例もあった(図5)。
上記の記載は本発明の特殊な態様に限定されたものである。しかしながら、本発明の利点の一部若しくは全部の達成には、本発明に対していくつかの変更及び改良を施すことが可能であることが明らかであろう。そのような態様も以下の特許請求項の範囲内にある。
