(被験化合物の経口投与による網膜切片評価)
視神経障害モデルとして汎用されるNMDA誘発ラット網膜障害モデル(Invest. Ophthalmol. Vis. Sci., 2003; 44: 385-392)を用いて、本化合物の有用性(網膜神経細胞死抑制効果)を評価した。
ラット[Slc:SD、雄性、約7週齢]に空気 1~1.5L/分で3-4%(V/V)イソフルランを気化させたガスを吸入させて全身導入麻酔し、2-3%(V/V)イソフルランの条件で維持麻酔した。その後、2mmol/Lとなるようにリン酸緩衝液(以下、「PBS」ともいう)に溶解したNMDA(Sigma製、[カタログ番号:M3262])溶液 5μL(NMDAとして10nmol)を硝子体内に投与した。
NMDA溶液の硝子体内投与3日後のラットに100mg/kgペントバルビタールナトリウム注射液を腹腔内投与して全身麻酔し、眼球を摘出した。摘出した眼球を25%(W/V)グルタルアルデヒド:10%(W/V)中性緩衝ホルマリン=1:9の混合液で固定した。固定した眼球をパラフィンで包埋した後に、薄切を行い網膜切片(3μm厚)を作製し、ヘマトキシリン-エオジンで染色した。網膜切片は1眼につき視神経乳頭部が入るように45μm間隔で8切片作製した。その8切片から任意に3切片を選択し、選択した切片について、視神経乳頭から約1.25mmを中心にして左右700~900μmの網膜の写真撮影を行い、網膜神経節細胞層中の細胞数(以下、「GCL細胞数」ともいう)を算出した(平均値)。得られたGCL細胞数から、式1に従い、無処置群を100%、10nmolNMDA硝子体内投与+基剤を経口投与した群を0%とした場合の各被験化合物のGCL細胞数減少抑制率(%)を算出した。尚、各群の例数は4匹(7~8眼)である。
GCL細胞数減少抑制率(%)=(NX-N0)/(NU-N0)×100
NU:無処置群のGCL細胞数
N0:10nmolNMDA硝子体内投与+基剤を経口投与した群のGCL細胞数
NX:10nmolNMDA硝子体内投与+各被験化合物を経口投与した群のGCL細胞数
NMDA硝子体内投与当日から眼球摘出日まで、毎日1回各個体の体重測定を実施した。各個体のNMDA硝子体内投与当日の体重を基準として、眼球摘出日の体重との差分を計算し、各個体の体重増加量を算出した(平均値)。尚、各群の例数は4匹である。
[NMDA硝子体内投与+基剤経口投与群]
PBSに溶解したNMDA溶液 5μL(NMDAとして10nmol)を硝子体内に投与した。また、0.5%(W/V)メチルセルロース水溶液を、NMDA硝子体内投与日から2日後までの3日間、10mL/kgの投与液量で1日2回反復経口投与した。尚、NMDA硝子体内投与日はNMDA硝子体内投与約1時間前および1~2時間の2回、0.5%(W/V)メチルセルロース水溶液を経口投与した。
PBSに溶解したNMDA溶液 5μL(NMDAとして10nmol)を硝子体内に投与した。また、0.5%(W/V)メチルセルロース液に懸濁させた各被験化合物を30mg/kgの用量で、NMDA硝子体内投与日から2日後までの3日間、10mL/kgの投与液量で1日2回反復経口投与した。なお、NMDA硝子体内投与日はNMDA投与約1時間前および1~2時間の2回、0.5%(W/V)メチルセルロース液に懸濁させた各被験化合物を30mg/kgの用量で、経口投与した。
対照化合物としてメマンチンを用いた。PBSに溶解したNMDA溶液 5μL(NMDAとして10nmol)を硝子体内に投与した。また、0.5%(W/V)メチルセルロース液に溶解させたメマンチンを30mg/kgの用量で、NMDA硝子体内投与日から2日後までの3日間、10mL/kgの投与液量で1日2回反復経口投与した。なお、NMDA硝子体内投与日はNMDA投与約1時間前および1~2時間後の2回、0.5%(W/V)メチルセルロース液に溶解させたメマンチンを30mg/kgの用量で、経口投与した。
被験化合物の例として、化合物A’および化合物B’を用いた場合の試験結果を表1に示す。表1から明らかなように、化合物A’、化合物B’および対照化合物であるメマンチンはNMDA誘発ラット網膜障害モデルにおいて生じる、網膜におけるGCL細胞数の減少を抑制した。
試験結果から、化合物A’および化合物B’を含む本化合物は経口投与等の全身暴露の投与形態において、体重増加抑制の副作用を示さずに、視神経障害の予防又は治療効果および網膜神経細胞死の抑制効果を有する。特に緑内障性視神経障害の予防又は治療効果を有する。一方、メマンチンは同様の視神経障害の予防又は治療効果及び網膜神経細胞死の抑制効果を有するが、体重増加抑制の副作用を示すため、上述の抑制効果には本化合物がより有用であることが示唆される。
(被験化合物の硝子体内投与による定量的Polymerase chain reaction(以下、「PCR」ともいう)評価)
(定量的PCRでの評価方法)
NMDA誘発ラット網膜障害モデルにおいて、視神経軸索の主構成成分であり、軸索の形態維持に重要とされるニューロフィラメント軽鎖(以下、「NFL」ともいう)の網膜組織中での発現量を指標に、被験化合物の有効性を評価した。
NMDAの硝子体内投与1日後のラットに100mg/kgペントバルビタールナトリウム注射液を腹腔内投与して全身麻酔した後に眼球を摘出、網膜を単離した。単離した網膜をホモジナイズし、QIAzol Lysis Reagent(QIAGEN製[カタログ番号:79306])およびRNeasy 96 Kit(250)(QIAGEN製[カタログ番号:74106])を用いてtotalRNAを抽出し、PrimeScript(登録商標) RT reagent Kit(TAKARA製[カタログ番号:RR037B])を用いてcDNAを合成した。QuantiTect Multiplex PCR Kit(1000)(QIAGEN製、[カタログ番号:204545])に添付されている説明書に従い、QuantiTect Multiplex PCR Master Mix、合成したcDNA、NFLのプライマー・プローブ(Sigma製[オーダーメード])およびグリセルアルデヒド3-リン酸デヒドロゲナーゼ(以下、「GAPDH」ともいう)のプライマー・プローブ(AppliedBiosystems製、[カタログ番号:4352338E])を混合し、定量的PCR装置(AppliedBiosystems製[カタログ番号:7500-03])でPCR反応を実施し、NFLおよびGAPDHの発現量を測定した。
相対的NFL発現量=(NFL発現量/GAPDH発現量)
[式3]
NFL回復率(%)=(EX-E0)/(EP-E0)×100
EP:無処置群の相対的NFL発現量
E0:10nmolNMDA硝子体内投与を行った群の相対的NFL発現量
EX:10nmolNMDAに各化合物を混合し、硝子体内投与を行った群の相対的NFL発現量
[NMDA硝子体内投与群]
30%(V/V)DMSO含有精製水に溶解したNMDA溶液 5μL(NMDAとして10nmol)を硝子体内に投与した。
30%(V/V)DMSO含有精製水に溶解したNMDAと被験化合物の混合溶液 5μL(NMDAとして10nmol、被験化合物として15nmol)を硝子体内に投与した。
被験化合物の例として、化合物A’および化合物B’を用いた場合の試験結果を表4に示す。表4から明らかなように、化合物A’および化合物B’は、NMDA誘発ラット網膜障害モデルにおいて生じるNFLの発現量の減少を回復させた。一方、同一用量のメマンチンもNFL発現量の減少を回復させたが、その強度は化合物A’および化合物B’に比べ、明らかに弱かった。
試験結果から、化合物A’又は化合物B’を含む本化合物は局所投与の形態においても視神経障害の予防又は治療効果予防又は治療効果を有し、また、NFLの発現量の回復効果も有する。一方、メマンチンは視神経障害の予防又は治療効果及び網膜神経細胞死の抑制効果を有するが、同一用量の局所投与では化合物A’又は化合物B’の効果よりも明らかに弱いことから、化合物自体が保有するポテンシャルは本化合物がより強力であることが示唆される。
