Abstract
【解決手段】 少なくとも1つの重合可能な基および少なくとも1つの潜在的反応性基を含む少なくとも1つのモノマーを、金属カルベン触媒の存在下で重合して、少なくとも1つの潜在的反応性基を有するポリマーテンプレートを形成する工程;およびこのポリマーテンプレートを、少なくとも1つの反応性基を含む少なくとも1つの官能化剤と、このポリマーテンプレートの潜在的反応性基がこの官能化剤の反応性基と効率的に反応するような条件下で結合して多価アレイを形成する工程を有する多価アレイの調製方法。
【選択図】 なし
Description
本発明の方法での使用のための官能化キャッピング剤および官能化されたカルベンROMP触媒もまた提供される。
触媒上の潜在的反応性基は、好ましいモノマー上の潜在的反応性基と類似しており、このモノマー中のこれらの反応基は、ROMP反応を妨げず、続く官能化を可能にする。
特定の好ましいキャッピング剤は、潜在性または非反応性官能基、およびエチレングリコール基の両方を含む。典型的に、これらの両方は、一つの部分、またはR6もしくはR7の部分を形成する。キャッピング剤の特に好ましい例には、保護されたカルボン酸誘導体にエチレングリコール鎖を介して連結されたアルキルビニルエーテルが挙げられる。その設計により、このリンカーは、タンパク質または疎水性分子との非特異的相互作用を最小にする。
キャッピング剤の代替として、ポリマーテンプレートは、触媒を、酸素または他の酸化剤で酸化し、ポリマーテンプレートの骨格の末端でアルデヒドを形成することによって、末端官能化され得る。例えば、ポリマーテンプレートは、単に空気に曝されるか、または室温および圧力下で酸素雰囲気下に置かれ得る。
本発明の方法は、官能化剤とポリマー(またはポリマーテンプレート)との間の標準的なカップリング技術を包含する。これらのカップリング技術は、選択される潜在的反応性基に依存し、そしてポリマーテンプレートの溶解度に依存する液体または固体状態の反応条件を含み得る。このような技術および条件は、当業者によって容易に決定され得る。
異なる骨格を有するポリマーテンプレートの例は、図9に示される。好ましい例のノルボルネンテンプレートに基づくポリマーテンプレートは、以下の一般構造を有する:
本発明のライブラリは、生物学的官能性であり得る所望の官能性を有する多価のアレイを、スクリーニング、選択および同定するために有用である。
本発明の目的および利点は、以下の実施例によりさらに例示されるが、これらの実施例に引用される特定の材料およびその量、ならびに他の条件および詳細は、過度に本発明を限定すると解釈されるべきではない。
4−ペンタン酸(1.0mL,9.8mmol,1当量)、K2CO3(6.78g,49mmol,5当量)、ベンジルブロミド(1.4mL,11.8mmol,1.2当量)およびヨー化テトラブチルアンモニウム(0.254g,0.686mmol、0.07当量)を約50mLの乾燥アセトン中で合わせた。この反応系を窒素下で3時間攪拌した。TLC(9:1、ヘキサン/酢酸エチル)は、出発物質以外示さなかった。この反応物を濾過し、そして溶媒を減圧下で除去した。残渣を酢酸エチルに溶解し、そして1M HCl、飽和NaHCO3、およびブラインで続けて洗浄した。有機層をMgSO4で乾燥し、そして減圧下で濃縮した。フラッシュカラムクロマトグラフィー(30:1 ヘキサン/酢酸エチル(ベンジルブロミドが溶出されるまで)〜1:1 ヘキサン/酢酸エチルの溶媒を使用する)を使用して、生成物(1.8g,9.5mmol,収率97%)を単離した。
Amberlyst15強酸樹脂を、以下の溶媒の各々で2回、以下の順序で洗浄することにより調製した:メタノール、水、1M NaOH、水、エタノール、6M HCl、水、エタノール、メタノール。
別々の反応容器において、ジクロロエタン(DCE)、および3,6−ジスルホガラクトースモノマー13のナトリウム塩(15mg,0.027mmol)、ドデシルトリメチルアンモニウムブロミド(DTAB)(13.5mg,0.044mmol)、および2,2−ビス(ヒドロキシメチル)−2,2’,2”−ニトリロトリエタノール(ビス−トリス)緩衝液(91μL,100mM,pH5.9)の溶液を、この溶液の各々を4回の凍結−吸引−解凍(FPT)サイクルに供することによって脱酸素した。脱酸素したジクロロエタン(45μL)を、窒素下でルテニウムメタルカルベン14(1.5mg,0.0018mmol)を含むバイアルに入れ、そしてこの紫色溶液を、モノマーおよびDTABの緩衝溶液を含む反応容器に添加した。
キャップされたポリマー21aをH2O(95μL)中に溶解させ、そして1MのNaOH(5μL)を添加した。このフラスコに指形冷却器を取り付け、そしてこの溶液を60℃で2時間加熱した。室温まで冷却した後、この溶液をH2Oで希釈して1mLの最終体積にし、そして中和した(AMBERLYST 15 強酸性の高度架橋樹脂,Aldrich)。この混合物をガラス綿の小さなプラグを通して濾過して樹脂を除去し、次いで乾燥するまで濃縮して、脱保護ポリマーを得た。
