- an allergen is inhaled in an atopic asthmatic patient to cause an immediate asthmatic response (IAR). That is, when an allergen is inhaled by an atopic asthmatic patient, an asthmatic reaction (bronchospasm) occurs after about 20 minutes, and the original state is restored after about 2 hours. After that, if we continue to observe the patients who had an immediate asthmatic response, it was found that in about half of the cases, bronchospasm occurred again after 6 to 10 hours, and late asthmatic response (Late asthmatic response: LAR) Named.
- IAR immediate asthmatic response
- bronchospasm reaction In late-onset asthma, the bronchospasm reaction lasts long and is accompanied by pulmonary hyperinflation, which is strongly suppressed by steroids. Therefore, it is recognized that bronchial asthma induced by the allergen attraction is important as a steroid-dependent clinical model of dyspnea of severe bronchial asthma. Immediate type reaction has been recognized as type I allergy resulting from mast cell activation by IgE antibody, and late type reaction has been recognized as T lymphocyte and eosinophilic allergy (eosinophilic inflammation). It was. These immediate and late reactions have been shown to occur in allergic rhinitis and dermatitis.

ラット肺膜を用いた化合物のレセプター結合評価試験
スガサワ等の文献(Sugasawa, T. et al., J. Biol. Chem., 272, 21244-21252(1997))記載の方法に従いおこなった。
ラット肺膜の調製
SD系雄性ラット(供試時7週令、日本チャールズリバー)摘出肺から気管および血管を除去、細断し、氷冷トリス-生理食塩水 緩衝液 (10mMトリス塩酸-154mM塩化ナトリウム、pH7.4)で洗浄した。これをホモジナイズ用緩衝液(1mMエチレンジアミン四酢酸(EDTA)、1mM 4-(2-アミノエチル)ベンゼンスルホニル フルオリド(AEBSF)、5μg/mlアプロチニン、5μg/mlロイペプチン)を含むトリス-生理食塩水 緩衝液中で氷冷しつつヒスコトロンでホモジナイズした(最高速度:1分)。低速遠心(1500×g、20分、4℃)後の上清を超遠心(100000×g、20分、4℃)し、ペレットをトリス-生理食塩水 緩衝液に懸濁し、-80℃で保存した。タンパク濃度はウシ血清アルブミン(BSA)をスタンダードにしてBio-Rad社製プロテインアッセイキットで測定した。
リガンド結合試験
タンパク非吸着性丸底96穴アッセイプレート(岩城硝子社より購入)の各ウエルに1nM[125I]-ヨードシアノピンドロール(アマシャム社より購入)、10μMセロトニン、20μm dl-プロプラノール、10μMフェントラミン、1.1mMアスコルビン酸および100μg肺膜を含むトリス-生理食塩水緩衝液200μlを添加し、ピペッティングして混合したのち、37℃で30分間インキュベートした。試験化合物は100%ジメチルスルホキシド溶液に溶解し、2μl(最終DMSO濃度:1%)添加した。また、非特異的結合量を求めるために試験化合物の代わりに、最終濃度100μMのL-スレオ-3-(3,4-ジヒドロキシフェニル)-N-[3-(4-フルオロフェニル)プロピル]セリンピロリジンアミドを添加した。この間、マルチスクリーンプレート(96穴 Bグラスファイバー、ミリポア Cat. No. MAFB NOB10)に0.3%ポリエチレンイミン(PEI)/トリス-生理食塩水緩衝液を100μl添加して30分以上インキュベートした。吸引濾過洗浄(200μl氷冷トリス-生理食塩水緩衝液を添加して吸引)し、96穴アッセイプレート上の反応液をマルチスクリーンプレート上で4回吸引濾過洗浄した。マルチスクリーンプレート底部のBグラスファイバー濾紙を打ち抜き、濾紙上にトラップされた[125I]-ヨードシアノピンドロールのγ線量を測定し、これを結合量とした。DMSO(最終濃度:1%)存在下の結合量を総結合量とし、100μML-スレオ-3-(3,4-ジヒドロキシフェニル)-N-[3-(4-フルオロフェニル)プロピル]セリンピロリジンアミド存在下の結合量を非特的結合量とした。総結合量から非特異的結合量を差し引いた値が特異的結合量である。化合物の結合活性は下記式にしたがって算出される、試験化合物が、[125I]-ヨードシアノピンドロールのラット肺膜SMBSへの特異的結合を抑制する割合で示した。

ラットより副腎を摘出し、D-MEM中で余分な結合組織、脂肪、皮膜を取り除いた。ポリチューブに副腎を移し、はさみにより副腎を素早く細分化し、1 mg/mL collagenase、0.25 μL DNase I含有のD-MEMを添加した後、37oCで10分間、80回/分で振とうした。その後、先をカットした1 mLのピペットチップを用いてピペッティングを行い、再度同一条件で振とうした。10分後に再度1 mLのピペットチップを用いてピペッティングを行い、細胞懸濁液を金属メッシュでろ過し、ろ液を4oCで5分間、500 gにて遠心した。上清を除去し、0.16 M NH4Clと0.17 M Tris-HClの混合溶液を3 mL添加した。氷上にて5分間静置した後、同一条件にて遠心を行った。その後、上清を除去した後、D-MEMを加え細胞懸濁液を作製し、同一条件にて遠心を行った。再度、上清を除去した後、D-MEMを加え細胞懸濁液を作製し、Cell Strainer (BD Falcon(登録商標))にて細胞懸濁液をろ過し、ろ液を同一条件で遠心を行った。遠心終了後、上清を除去し、1% Penicillin Streptomycin Mixed Solution、10% FBS含有のD-MEMを添加し、Multiple well plates for adhesive cell culture, 96 wells (IWAKI)に10000 cell/wellずつ播種し、37 oCで一晩、CO2インキュベーターにてインキュベーションした。
細胞を播種したプレートを一晩インキュベーションした後、培地を取り除き、20 μM被験物質含有のD-MEMを50 μL/well添加した後直ちに20 μM cAMP含有のD-MEMを50 μL/wellで添加し、被験物質の終濃度を10 μMとした。2種のD-MEMを添加後、37 oCで2時間、CO2インキュベーターにてインキュベーションした。2時間経過後、培地の上清50 μLを回収した。細胞については、Cell Titer-Glo(登録商標)(Promega)を用いて定法に従い被験物質の細胞毒性を評価した。回収した上清は、Corticosterone EIA kit (Cayman)を用いて定法に従い上清中のCorticosterone濃度を測定した。
被験物質による細胞毒性が認められないことを確認した上で、10 μM被験物質のCorticosterone生成に対する阻害率を下記に示す式に従い算出した。
モルモット遅発型喘息モデルにおける化合物の評価
実施例52で得た化合物を用いて評価試験を行った。
Hartley系雄性モルモット(日本エスエルシーより購入)を入荷後予備飼育を約1週間した後、2%(w/v)卵白アルブミン(OA)生理食塩水を超音波式ネブライザー(OMRON NE-U12、条件:霧化量最大、風量最大)を用いて、プラスチックボックス(4匹/ボックス)内にて5分間吸入暴露させ、感作した(day 0)。同様の操作を7日目に行った。14日目または15日目に1匹ずつ、2%OAを5分間吸入させ反応を惹起させた(チャレンジ)。このチャレンジの1時間前に抗ヒスタミン剤のマレイン酸ピリラミン(生理食塩水に溶解、10mg/2ml/kg)を腹腔内投与した。 試験化合物は0.5%メチルセルロース(MC)に懸濁し抗原チャレンジの1時間前、3mg/5ml/kg経口投与した。コントロール群には同様に0.5%MCを投与した。
呼吸機能の測定、解析はハトソンらの方法(Penny A. Hutson et al. Am Rev Respir Dis 1988 137, 548-557)に準じて行った。抗原チャレンジ前(薬物投与前)および抗原チャレンジ5分、、1、2、3、4、5、6、7、8時間後に呼吸機能を測定し、波形をMacLab Chart v3.4(AD Instruments)を用いて取り込み、後刻これを用いて解析した。評価は、sRaw/TVを指標に行い、それぞれの各個体において各時間のsRaw/TVから前値のsRaw/TVを減じた値を求めた。測定時間に対し、前値を減じたsRaw/TV値をプロットし、抗原チャレンジ4~8時間の時間帯において各個体のarea under the curve(AUC4-8hr)を求め、比較した。統計解析にはSAS前臨床パッケージVersion5.0を用いて行った。Dunnett型多重比較により、Control群と各薬剤添加群との間に有意差が認められるかどうか検定した。
結果を表11に示す。
