[調製例1]
次のように、大腸粘膜標本を作製した。
マウスを頚椎脱臼し、腹部切開後、盲腸を摘出した。盲腸と小腸及び大腸との境界部分を切断して、盲腸を摘出した。盲腸内にハサミを入れてシート状に切り開いた。内容物を完全に除去するために、盲腸をピンセットでつまみ、代用液で洗浄した。ラバーの敷かれたシャーレに代用液を入れて、漿膜側を上にして貼り付けた。常にシャーレ内の代用液に95% O2/5% CO2を通気した状態で、ピンセットを用いて筋層を剥離し、粘膜及び粘膜下層からなる標本を作製した。これを4分割して実験に用いた。
窓の面積0.2 cm2 、代用液5 mLを含む2つのUssing typeのチャンバーの間に粘膜標本を装着した。電位差測定用には、チャンバーの両側に一対のカロメル電極を1MKCl /2%寒天溶液塩橋によって接続した。通電用には1MNaCl/2%寒天溶液塩橋によって接続したAg/AgCl電極を装着した。これらをボルテージクランプ装置に接続し、短絡電流Iscを測定した。Iscは粘膜側より漿膜側への電流を正とした。
テトロドトキシン(TTX)を漿膜側に投与し神経を遮断後、フォルスコリン (FK)を漿膜側に投与した。細胞内cAMPを上昇させるフォルスコリンにより、Iscは大きく上昇した。このcAMP依存性のIsc上昇の少なくとも一部はCl- 分泌機構活性化によるものである。
その後、前記化合物1を漿膜側に投与したところ、Iscは低下した(Cl- 分泌は抑制された)。更にchromanol293B(K+ チャンネルKCNQ1を阻害する)を漿膜側に投与したが、chromanol293B投与で見られるIsc抑制反応(図4に示す実施例2)は消失した。最後にNa+ ・K+ ・2Cl- 共輸送体阻害剤(Cl- 分泌を阻害する)を漿膜側に投与したところ、Iscの僅かな低下が見られた。この僅かな低下は、Cl- 分泌を支える漿膜側のK+ チャネルとしてKCNQ1以外も一部関与しているため(図1)、KCNQ1を完全に阻害してもCl- 分泌は完全に抑制されず、その残された部分の抑制を表わしている。
図3に示した実施例1と同様の実験であるが、chromanol193Bを先に投与した。図3で見られた化合物1によるIsc低下はchromanol193B投与後の場合には見られなかった。
この場合も、mentholによるIsc低下はchromanol193B投与後の場合には見られなかった。
次のように、胃標本を作製した。
マウスを頸椎脱臼し、腹部切開後、胃を摘出した。胃酸分泌部を切り出し、代用液で洗浄後、2分割した。
この標本を用いて胃酸分泌活性を以下のようにして測定した。
窓の面積0.2 cm2 、代用液10 mLを含む2つの向かい合ったチャンバーの間に標本を装着した。37℃にてpH電極を用い管腔側を浸す代用液のpHの低下を継時的に測定した。実験終了後測定されたpHの低下と予め測定しておいた代用液の緩衝能から、胃酸分泌速度を算出した。胃酸分泌を刺激するためにHistamine(1mM)を予め漿膜側の代用液に投与して実験を行った。
l-メントール及び化合物1は、最終濃度がそれぞれ50μMと100μMになるように管腔側の代用液に投与した。その際、DMSOを溶媒とし目的終濃度の1000倍に調整したstock solutionより投与した。投与した時刻は、それぞれ20分、14分経過時である。
胃酸分泌速度(microEq/cm2 /h)の算出値を、表1に示す。
胃酸分泌速度は、化合物1(100μM)により75%(実施例1)、1-メントールにより57%(実施例2)抑制された。
以上のように、本発明によると、冷感組成物の作用によってカルシウムチャンネルが阻害され胃酸分泌が抑制されることが示された。
