H1受容体に対する結合研究によって、ヒスタミンH1受容体親和性を決定した。使用したサンプルは、ヒトH1受容体(5mg/ml、PerkinElmer)によってトランスフェクトしたCHO細胞の膜の懸濁液(使用まで−80℃において保存)である。解凍後、精製水によって調製したアッセイ緩衝液(50mMリン酸Na/K)中において、膜をホモジナイズし、室温(pH7.4)に維持した。96ウェルマイクロプレートにおいて、アッセイを実施した。各ウェルにおいて、25μlの緩衝液および25μlのビヒクル(全結合)または10μMピリラミン(非特異的結合)または試験すべき生成物を追加した。続いて、200μlの膜懸濁液をすべてのウェルに追加し、マイクロタイタープレートを25℃において15分間プレインキュベートした。この時間後、25μlの3H−ピリラミン(1.5nM)を追加し、反応物を25℃において60分間インキュベートした。次いで、真空ろ過(Multiscreen microplate Screener)によって、アッセイ緩衝液(4℃)による10回の洗浄を実施して、結合した放射性リガンドから遊離放射性リガンドを迅速に分離した。続いて、45μlのシンチレーション液を各ウェルに追加し、マイクロプレートを密封した後、液体シンチレーションカウンター(TopCount)によって、放射能を定量した。GraphPad Prismプログラムを用いて、阻害曲線のグラフおよび計算IC50値を求めた。IC50値を表1に示す。
