1)一般的な合成経路
本発明による式(I)の化合物(すなわち、PXT002331)は、容易に入手できる出発物質から、溶液相もしくは固相化学プロトコルまたは溶液相および固相混合プロトコルを用いる幾つかの合成法により製造できる。たとえば、式(I)の化合物は下記に示す合成スキームを用いて製造できる。
オキシムの導入は、誘導体IVとヒドロキシルアミン塩酸塩(HONH2,HCl)をピリジンまたはエタノール中においてマイクロ波条件下で反応させてクロモンオキシム高次中間体を直接得ることにより達成でき、それは数工程の反応でPXT002331になる。PXT002331になるこの高次中間体は、上記に示した2工程法を用いて、エタノール中でtert−ブチルヒドロキシルアミン塩酸塩(tBuONH2,HCl)を用い、続いて塩酸(HCl)などの酸性条件下で、極性溶媒、たとえばTHFおよび酢酸の混合物中においてtert−ブチル基を脱保護することによる後続工程で得ることもできる。
アルキレン側鎖の導入は、パラジウム触媒によるクロスカップリング反応、たとえば市販の亜鉛試薬および適宜な配位子/パラジウム触媒系を用いる根岸クロスカップリングにより達成される。後続の官能化、続いて弱い還元剤、たとえばトリアセトキシボロヒドリドを用いる標準的な還元アミノ化により、高次中間体VIIが良好な収率で得られる。酸性条件下でのオキシム保護基の最終的な脱保護により、式(I)の化合物、すなわちPXT002331になる。
下記の実験の記載に用いた市販の出発物質は、別にレポートしない限りAldrich、Sigma、ACROSまたはABCRから購入された。

本発明による式(I)の化合物(すなわち、PXT002331)を、WO 2011/051478の例171に記載されたカルシウムアッセイを用いて、ヒトmGluR4に対するそれのアゴニストおよび/またはポジティブアロステリックモジュレーター活性について試験した。PXT002331はpEC50=7.12の力価(約0.076μMのEC50に相当する)をもつことが認められ、それは7.44のpEC50(約0.036μMのEC50に相当する)をもつWO 2011/051478の例127の化合物(すなわち、“PXT001858”)のものに匹敵する。
PXT002331およびPXT001858を10mg/kgで雄Sprague−Dawleyラットに経口投与(p.o.)した。投与体積は10ml/kgであった。並行してPXT002331を1mg/kgで2ml/kgの投与体積により静脈内(i.v.)にも投与した。血液試料(200μl)を、経口投与については15分から24時間まで、静脈内投与については5分から24時間までの範囲の時点で、0.2% K2EDTAを入れた氷冷チューブに採集した。チューブを10,000rpmで5分間、4℃で遠心した。血漿(上清)を別のチューブに分離し、分析するまで−80℃で保存した。動物3匹の2グループをそれぞれの投与経路に用いた:1グループにおいては24時間の期間にわたって血液試料を採集して血漿曝露を決定し、第2グループにおいては血液と脳を最後の1時点で採集して(0.5、1.0、1.5、2.0、4.0時間目)、脳曝露の動態および脳/血漿比を決定した。
血漿試料および脳ホモジェネート中の親化合物(遊離塩基)それぞれをLC−MS/MS法により分析した。濃度をng/ml血漿またはng/g脳組織で表示する。
10mg/kgで、同じビヒクル(Tween−80/エタノール/30% HPBCD(2/10/88))を用いて、PXT002331はそれのAUC(1.1倍)およびCmax(0.7倍)に反映されるようにPXT001858に匹敵する血漿曝露を示した。この実験におけるPXT002331の経口による生物学的利用能は39%であった。それらの経口吸収が類似するにもかかわらず、PXT002331は、PXT001858と比較した場合、より高い脳/血漿比(6.5対2.0,T=1.5時間目;図4を参照)をもち、脳AUCの3倍改善をもたらす。帰納的に、可能性のある1つの仮説は、経口吸収に際しての腸および肝臓における第II相コンジュゲーションの相異を拠りどころとすることができた。両方の化合物をインビトロでUGT(UDP−グルクロノシルトランスフェラーゼ)の存在下でアッセイすると、PXT002331はPXT001858と比較してはるかに低いレベルのグルクロニデーションを示した(参照:下記の表)。それにもかかわらず、インビトロでみられたこの相異自体ではPXT002331について得られた予想外に有利なPK結果を説明することはできない。これらの実験で得られた結果を下記の表1〜3および図1〜4にまとめる。
本発明による式(I)の化合物(すなわち、PXT002331)の抗パーキンソン病効力を、1−メチル−4−フェニル−1,2,3,6−テトラヒドロピリジン(MPTP)パーキンソン病のマカクモデル(カニクイザル(Macaca fascicularis)の種のマカクを使用)を用いて評価した;これはパーキンソン病の臨床的および病理学的特徴の大部分を再現し、“ゴールドスタンダード”とみなされる(MPTPモデルについては、Porras G et al., Cold Spring Harb Perspect Med., 2(3):a009308, 2012 およびそれに引用された参考文献を参照)。
マカクにおいて実施した各試験(参照:実施例3)に際してPXT002331の有害事象および副作用を分析した。
単独またはL−ドパを伴うPXT002331が行動に何ら明らかな有害な変化を誘発することはなかった(旋回(circling)、興奮(excitement)、無気力(lethargy)、眠気などのいずれも)。よって、これらの処置は高用量ですらすべての被験MPTPマカクによって良好に耐容され、何ら明らかな有害作用を伴うことなく増強された抗パーキンソン病応答が有益となる。
長期低用量MPTP投与を受けたサル(CLD MPTPマカクモデル)は、変動性応答遅れ(VDR)タスクで測定して、認知障害を発現する。したがって、認知症状に対する副作用の可能性を査定するために、これらの動物において認知に対するPXT002331の影響を評価することを決定した。
単独またはL−ドパと組み合わせたPXT002331の投与がジスキネジアを誘発することはなかった。実際に、単独またはいずれかの試験用量のL−ドパと組み合わせたPXT002331の投与後、CLD MPTPマカクにジスキネジアは誘発されなかった。初期PDのこのモデルにおいてはL−ドパ単独ですらジスキネジアを誘発しなかったことに注目すべきである(参照:図8,左半分)。
PD患者と同様に、MPTPマカクはそれらの長期L−ドパ療法の副作用を示し、それにはL−ドパ誘発性ジスキネジア(LID)が含まれる。これは、この実験で用いた進行期パーキンソン症候群のMPTPマカクに該当していた。PXT002331をこれらのサルにおいて25mg/kgの用量でL−ドパと併用して試験した。
