本発明の化合物は、ケモカイン受容体、特にCCR2受容体に対する親和性を示すことが見出された。このような親和性は、典型的には、適当なアッセイにおいて受容体からの刺激反応の50%を阻害するのに必要な化合物の濃度としてのIC50から算出され、下記式によって計算される「Ki」値として報告される:
膜調製
5%CO2雰囲気下、37℃で、10%ウシ胎仔血清、2mM L−グルタミン、G418を添加したDMEM F12培地中にて、ヒトCCR−2受容体を発現しているCHO細胞を増殖させた。0.6mM EDTAを含有するハンクス緩衝塩溶液(HBSS、Ca2+、Mg2+不含)を用いて、コンフルエントな細胞を回収した。得られた細胞懸濁液を4℃にて300gで10分間遠心分離し、細胞ペレットをHBSS+EDTA 100mLに再懸濁し、300gで5分間、再度回転させた。得られた細胞ペレットを100mMロイペプチン、25μg/mLバシトラシン、1mM EDTA、1mM PMSFおよび2μMペプスタチンAを含有する50mM HEPES(pH7.4)に再懸濁した。氷冷ブレンダーを用いて、該懸濁液をホモジナイズし、500gで20分間遠心分離した。上清を取り除き、48000gで30分間回転させた。この細胞ペレットを、上記緩衝液からペプスタチンAおよびPMSFを除いたものに再懸濁し、アリコートに分けて−70℃で貯蔵した。
アッセイのために、膜を解凍し、アッセイ緩衝液(20mM HEPES、10mM MgCl2、100mM NaCl、pH7.4、1mg/mLサポニン、10mM GDPを含有)に再懸濁して、最終濃度5μg/ウェルを得た。該膜とLEADseeker SPAビーズ(0.25mg/ウェル)とを混合しながら室温で30分間予備結合させた。Biomek FXにて調製した、384ウェルプレートの全域で11ポイントの4倍希釈液として100%DMSO中に種々の試験化合物(30μM〜30pM)0.5μLを含有するアッセイプレートをアッセイにおいて用いた。該プレートはまた、実験において高い対照および低い対照を生じさせるために、DMSOを16ウェル含有し、高濃度の標準アンタゴニストを16ウェル含有した。これにビーズおよび膜混合物15μLを[35S]GTPgS(最終アッセイ濃度0.2nM)15μLおよびEC80(40nM)のMCP−1 15μLとともに添加した。このMCP−1の濃度は、この受容体に対して作成されたアゴニスト曲線から予め決定された。添加はすべて、マルチドロップを用いて行われた。次いで、プレートを密封し、300rpmで5分間遠心分離した後、それらを室温で3時間インキュベートした。その後、それらをViewlux画像システムで読み取った。データの取り扱いについては、高い対照および低い対照を用いてデータを正規化し、次いで、エクセルにて四パラメーターキットを用いて適合させた。
以下のスキームは、本発明の化合物の製造方法を例示する。言及している特定の溶媒および反応条件もまた例示であって、限定しようとするものではない。記載されていない化合物は、市販品であるか、または入手可能な出発物質を用いて当業者によって容易に製造される。
以下の実施例は、例示目的のためだけであり、本発明の範囲を限定しようとするものではない。化合物は、ACD Name Pro 6.02ソフトウェア(Advanced Chemistry Development)を用いて命名した。
トルエン(55mL)にフェニルヒドラジン(19.8ミリモル、2.13g)およびTFA(59.3ミリモル、6.8g)を撹拌しながら添加した。該溶液を35℃に加温し、上記からの残留物(3.9g)をトルエン(10mL)中にて2時間にわたって加えた。反応物を35℃で一夜撹拌し、次いで、さらに24時間70℃に上昇させ、次いで、0℃に冷却した。メタノール(4.5mL)を添加し、次いで、NaBH4(27ミリモル、1.02g)を添加した。室温に加温した後、該溶液を6%NH4OHで洗浄し、有機物質を真空中にて濃縮した。残留物を逆相クロマトグラフィー(14分間にわたって10〜50%アセトニトリル/水(0.1%TFA))によって精製して、3'−メチル−1'−(フェニルメチル)−1,2−ジヒドロスピロ[インドール−3,4'−ピペリジン](2.9g)を得た。MS(ES)m/e 293 [M+H]+。1H NMR(400MHz,DMSO-d6) δ ppm 0.61(d,J=6.78Hz,3H), 1.88(d,J=14.31Hz,1H), 2.07(td,J=13.99, 3.89Hz,1H), 2.23(ddd, J=12.30, 6.90, 3.89Hz,1H), 2.84-2.98(m,1H), 3.06(br.s.,1H), 3.35(d,J=10.54Hz,2H), 3.19-3.43(m,1H), 3.57(d,J=10.54Hz,1H), 4.24-4.47(m,2H), 6.69(d,J=7.78Hz,1H), 6.77(t,J=7.40Hz,1H), 6.95(d,J=7.28Hz,1H), 7.07(t,J=7.53Hz,1H), 7.36-7.61(m,6H), 10.01(d,J=2.01Hz,1H)。
