塩化アセチル(52mL、0.73mmol)をメタノール(500mL)及びクマリン酸(50g、0.36mol)の混合液に、撹拌しながら、約0℃で約10分間ゆっくり滴下した。得られた反応溶液を10時間、還流下で撹拌した。液体クロマトグラフィーで反応の終結を確認した後、反応生成物を、メタノールを用いて減圧下で蒸留して化合物を得た。この化合物を水と酢酸エチルで3回抽出し、有機相を減圧にて、カラムクロマトグラフィー(ヘキサン:酢酸エチル=1:5)で精製して、標的化合物を得た(実収量:38g、収率:53%)。

ヘテロマーα7nAChRの活性をFlexStation-Ca2+influx assayにより評価した。α7nAChRがCa2+透過性非−選択的カチオンチャネルであることを考慮して、本実施例では、蛍光染料カルシウム−3(Molecular Deviceから入手可能)及びFlex Station II機器(Molecular Deviceから入手可能)を使用して、細胞内Ca2+濃度の変化を測定した。
ヒトCHRNA7 (NM_000746) cDNA ORF クローン (C/N RC221382; Origene)とヒトRIC (NM_024557) cDNA ORF クローン (C/N RC205179; Origene)をpcDNA2.1/Zeo(+)ベクター(Invitrogen, Co.から入手可能)にサブクローニングし、ヒトα7nAChRがトランスフェクトされたHEK293T/17細胞(ATCC、CRL−11268)を作出した。その後、該細胞を、増殖培地(ダルベッコ変法イーグル培地(DMEM)(Invitrogenから入手可能)、熱で不活性化された10%ウシ胎児血清(FBS, Invitrogenから入手可能)、300μg/mLのジェネテシン(Invitrogenから入手可能)、250μg/mLのZeocin(Invitrogenから入手可能)、及び1×ペニシリン/ストレプトマイシン(Invitrogenから入手可能)から成る)中に懸濁させ、Ф150mmプレートに播種した。アッセイ開始の24時間前に、懸濁液で増殖させた細胞を採取した後、遠心分離し、5×105細胞/mLの濃度で増殖培地中においてさらに懸濁した。この細胞懸濁液を、ポリ−D−リシンがコートされた透明底を有する96−ウェル黒色プレート(Biocoat,BDから入手可能)に、1ウェル当たり5×104個の細胞で、分注した。該プレートを、細胞を5%CO2において約37℃で24時間、培養した。
アッセイ当日に、増殖培地を除去した後、アッセイバッファー(7 mM Tris-Cl, 20 mM HEPES, 20 mM NaCl, 5 mM KCl, 0.8 mM MgSO4, 4 mM CaCl2,120 mM NMDG, 5 mM D-グルコース, pH 7.4)で細胞を1回洗浄した後、アッセイバッファーで希釈したカルシウム−3染料を1ウェル当たり約100μLずつ添加し、室温で1時間保管した。試験化合物(100%DMSO内の10mMストック)を、アッセイバッファーを用いて様々な濃度(最高濃度約40μMから1/3低く)に希釈し、Ca2+透過性シグナル伝達の増幅のためのPNU−120596(Sigmaから入手可能)を、分析緩衝液を用いて約30μMに希釈した。は最終濃度約1μMのエピバチジン(Sigmaから入手可能)を、ポジティブコントロール群として使用した。
細胞内Ca2+濃度の変化を測定するために、プレートを室温で約1時間保管し、該試験化合物希釈プレートをFlex Station II装置に設置し、薬物を添加する前約30秒間の細胞の蛍光を測定した後、PNU−120596を添加し、120秒間蛍光の変化を測定しており、試験化合物に露出させた後、90秒間、蛍光の変化を測定した。細胞を試験化合物に曝露した後、約90秒間の蛍光の変化を測定した(励起485nm/蛍光525nm)。各濃度での最大蛍光値を記録し、ポジティブコントロール群に対する相対的な蛍光値に基づいて、非線形回帰分析法を用いて試験化合物のEC50を決定した。

NORTは、マウスの性質(すなわち、新しい物体を探索する嗜好性)を利用して、以前に経験した物体を記憶することができるか否かを測定するための認知記憶試験であり、EnnaceurとDelacourにより初めて紹介された[Ennaceur A and Delacour J (1988) A new one-trial test for neurobiological studies of memory in rats.1; Behavioral data. Behavioral Brain Res. 31;47-59]。このNOR試験は、健忘症誘発薬物かまたは他の一般的な薬物のいずれかを投与した齧歯類における事物記憶の変化を測定するための大衆的な実験法であり、それにより、健忘症誘発薬物を投与した齧歯類における試験薬物の記憶回復効果を調査する。本実施例では、BevinsとBesheerの記載[Bevins, R.A.& Besheer, J. Object recognition in rats and mice; a one-trial non-matching-to-sample learning task to study 'recognition memory'. Nat Protoc. 2006;1(3);1306-11. (2006)]に従って試験を行った。体重約20〜32gの雄ICRマウス(Orient Bio Inc., Koreaから入手可能)に、30%PEGに溶解させた試験化合物を、0.03〜3mg/kg体重及び10mL/kg体重の用量で経口投与し、投与から30分後、生理食塩水に溶解させたMK−801(Sigmaから入手可能)を0.1mg/kg体重及び10mL/kg体重の用量で皮下投与して、健忘症を誘発させた。MK−801の投与から30分後、箱に予め設置したステンレススチールの四角柱またはプラスチックの円柱を5分間探索させた。該探索から24時間後、以前あった2つの物体のうち1個を新しくもので置き換え(すなわち、ステンレススチールの四角柱1個とプラスチックの円柱1個が含まれる)マウスが探索するのにかかる時間を約5分間測定した。認識指数(RI)は、[(試験化合物群の新奇物体探索時間/試験化合物群の全物体探索時間)/(MK801群の新奇物体探索時間/MK801群の全物体探索時間)×100]として定義される。
