化合物49~55の構造を下記表15に記す。
実験には、Hartley系モルモット(雄、初回感作時6~7週齢)を用いた。
入荷した動物は、検疫及び順化のため、7日間以上の予備飼育後、実験に使用した。
初回感作として、1ml中に卵白アルブミン(OVA)1mg及び水酸化アルミニウムゲル(Alum)10mgを含有する生理食塩水溶液を、動物あたり1ml背部皮下に投与した。初回感作1週間後の1回、又は1週間後と2週間後の2回、10mg/mlのOVA生理食塩水溶液を20μlずつ、マイクロピペットを用いて両側の鼻腔内に投与することで局所感作を行った。
群分けは、感作終了日の体重及び感作開始日から感作終了日までの体重変動を指標とし、二次元層別無作為抽出法により行なった。
最終感作1週間後、20mg/mlのOVA生理食塩水溶液を10μlずつ、両側の鼻腔内に投与し、抗原抗体反応を誘発した。Control群(非誘発群)には同様に生理食塩水を投与した。
被験物質は、誘発30分前に、10μlずつ、両側の鼻腔内に投与した。被験物質は、生理食塩水に溶解し、500μg/mlの濃度の溶液を投与に使用した。Control群(非誘発群)及びSaline群(溶媒対照群)には、同様に生理食塩水を投与した。尚、対照薬(化合物0)として「Flunase」(グラクソ・スミスクライン株式会社製)を使用した。
鼻腔抵抗の測定は、誘発当日の誘発前、誘発10分後、2、3、4、5、6及び7時間後に行った。各測定時間に1回、それぞれ100呼吸分の鼻腔抵抗(nasal airway resistance, nRaw)を測定し、その平均値を各測定時間におけるnRawとし、nRawの増加率を算出して鼻腔抵抗の指標とした。
鼻腔抵抗(nRaw)の増加率(%)は次式で求めた。
図99及び図100から、本発明化合物は、即時型アレルギー反応抑制効果を示すとともに、遅発型アレルギー反応抑制効果を示す。
実験には、Hartley系モルモット(雄、5週齢以上)を用いた。
モルモットにOVAを免疫して得た抗OVA血清を生理食塩水で500倍に希釈した(A液)。
下記表16に示す被験物質を生理食塩水で200μg/mlに希釈した(B液)。
B液を250倍に希釈したモルモット抗OVA血清と等量ずつ混合し、最終濃度を被験物質100μg/ml、抗OVA血清500倍にした(C液)。
エーテル麻酔後に背部剪毛したモルモットの背部に、1スポットあたり100μlの生理食塩水、A液、あるいはC液を皮内注射した。
約3時間後に、0.2~0.4%のOVAを含む0.5%エバンスブルー生理食塩水溶液を0.8~1ml/bodyで静脈内投与した。
30分以内に放血して皮を剥ぎ、各スポットの色素量を画像処理により定量した。画像処理において、抗OVA血清のみ投与のスポットの色素量を100%とした時の被験物質による抑制度を調べた。結果を表16に示す。(N = 3 or 6)
実験には、Hartley系モルモット(雄、5週齢以上)を用いた。
被験物質を生理食塩水にて100μg/mlに希釈した。
また、コントロールとして硫酸化ヒアルロン酸(4糖~約70糖の混合物;特開平11-147901号公報の実施例(製造例1)などに従って合成。)を用いた。
エーテル麻酔後に背部剪毛したモルモットの背部に、1スポットあたり100μlの生理食塩水、あるいは被験物質の生理食塩水溶液を皮内注射した。
0.5%エバンスブルー生理食塩水溶液を1ml/bodyで静脈内投与した。
30分以内に放血して皮を剥ぎ、各スポットの色素量を画像処理により定量した。
結果を、デキストラン(dextran sulfate 10000)投与のスポットの色素量を100%とした時の被験物質の血管透過率として図101~図103に示す。
化合物4及び化合物50について、1mg/ml水溶液を調整し、HPLC分析を行なった。
これらの溶液を冷所(2~8℃)及び室温でそれぞれ保存し、経時的に4ヶ月までHPLC分析を行い、それぞれのピークのパターン変化を調べた。
