ニューロキニン1（NK1）受容体拮抗作用（in vitro）
チャイニーズハムスター卵巣由来細胞株に発現させたヒトNK1受容体に対する125I-サブスタンスPの結合を阻害し、そのIC50値は0.1nmol/L、Kd値は86pmol/L（Hill係数＝1.1）であった。23)
サブスタンスP-O-メチルエステル（NK1受容体作動薬）誘発回腸縦走筋収縮に対し拮抗作用を示し、そのKa値は0.09±0.02nmol/L（n＝3）であった。一方、（Nle10）-ニューロキニンA〔4-10〕（NK2受容体作動薬）誘発による気管収縮、及びセンクタイド（NK3受容体作動薬）誘発による上頸神経節脱分極反応に対し、1μmol/Lの濃度において作用を示さなかった。23)
