1.シグマ受容体に対する親和性評価
測定系としては、シグマレセプターとしてモルモット全脳から得られた膜標品を用い、放射性リガンドとしては、[3H](+)−ペンタゾシンを用い、陽性物質として(+)−ペンタゾシンを用い、緩衝液には50mMトリス塩酸緩衝液(pH7.4)を用いた。また、被験物質として、化合物[2]〜化合物[12]を用いた。試料調製は、それぞれの被験物質、参照化合物又は陽性物質を秤量し、それぞれの被験物質、参照化合物(SA4503)、陽性物質(ハロペリドール)ともに、以下に示す最終濃度になるように緩衝液を用いて調節した。
濃度(mol/L):1×10−6、1×10−7、1×10−8、1×10−9、1×10−10、1×10−11
なお、比較検討用の参照化合物についても測定した。
阻害率は、「100−結合率」の式から求めた。結合率は下記式:
[(B−N)/(B0−N)]×100(%)
で表される。式中、Bは被験物質、参照化合物又は陽性物質と放射性リガンドとの存在下での膜標品への結合放射能量、B0は放射性リガンドのみを添加し、被験物質も参照化合物も陽性物質も非存在下での膜標品への結合放射能量(平均値)、Nは非特異的結合放射能量(平均値)である。
Y=aX+b
ここで、Y=logity=ln(y/(1−y))、X=logx、a及びbは定数である。ただしxは被験物質の溶質濃度である。化合物[3]〜[7]の結果を表3に示す。
被験物質によるラット大脳皮質神経細胞の神経突起伸展促進効果を以下の方法で評価した。妊娠18日のWistarラットを使用し、Springer Neuroscience Lab Manualの方法に準じて大脳皮質神経細胞を単離した。すなわち、エーテル麻酔下、妊娠ラットの子宮から18日目の胎児ラットを取り出し、HBSS(Gibco社製)を入れた氷上のシャーレに移した。実体顕微鏡下で大脳皮質を切り出した。切り出した大脳皮質を神経細胞分散液(住友ベークライト社製)を用いて分散させることにより、ラットの大脳皮質細胞を調製した。
細胞播種約3時間後、培養液中にそれぞれの被験物質として化合物[2]、化合物[3]、化合物[4]、化合物[5]、化合物[6]、化合物[7]、化合物[8]、化合物[9]、化合物[10]、化合物[11]、化合物[12](最終濃度0.3μM及び1.0μM)を添加し、無添加を対照とした。
突起形成細胞率=[突起形成細胞数/同視野内総細胞数]×100
結果を表4に示した。数値は平均±標準誤差を表す。また、化合物[2]の結果を図1、2に示した。
