(1)ヒト多血小板血漿の調製
抗凝固剤として3.8w/v%クエン酸ナトリウムを用い、クエン酸ナトリウム溶液:血液(体積比)=1:9の割合で、ヒト上腕静脈より採血し、遠心(120×g、10分間)して、上層の多血小板血漿(PRP)を得た。更に、PRPを除いた血液を遠心(1700×g、10分間)し、乏血小板血漿(PPP)を得た。PRPの血小板数を測定して、血小板数を25×104/μLにPPPで希釈調整した。
血小板凝集能の測定はBornの方法(Nature, 1962, vol.194, p.927-929)に準じ、血小板凝集能測定装置(PRP313M、アイ・エム・アイ株式会社)を用いて行った。PRP 190μLをガラスキュベットに入れ、血小板凝集能測定装置に装着後、被験物質として本発明化合物、リマプロスト(陽性対照物質)又は対照(0.25vol%ジメチルスルホキシド〔DMSO〕)を5μL加え、37℃で10分間インキュベートした。凝集剤としてADP(株式会社エル・エム・エス)を終濃度が3μmol/Lになるように5μL加え、凝集を惹起し、凝集の最大反応を測定した。
対照の最大凝集率を100%として、被験物質の凝集抑制率を求め、SAS System Version 9.1.3(Stat Preclinica Client Ver. 1.1 株式会社SAS Institute Japan)の「Dx計算(直線のあてはめ):ロジット変換なし」を用いてIC50を求めた。さらに、リマプロストのIC50値の活性を100とした時の各被験物質の相対活性(%)を算出した。
結果を表1に示す。表1によれば、本発明化合物は、in vitroヒト血小板凝集抑制作用試験において非常に強力な活性を示し、リマプロストの10倍以上の活性を示すものもあった。

上記試験例1の(1)と同様に、8~9週齢のSD系雄性ラットの腹部大動脈より採血して、血小板数を63.2×104/μLにPPPで希釈したPRPを調製した。
ADPの終濃度が2μmol/Lである以外は、上記試験例1(2)と同様に、被験物質として本発明化合物、プロスタグランジンE1(PGE1:陽性対照物質)又は対照を加えた場合の凝集の最大反応を測定した。
上記試験例1の(3)と同様に、被験物質の凝集抑制率からIC50値を求め、PGE1のIC50値の活性を100とした時の各被験物質の相対活性(%)を算出した。
結果を表2に示す。本発明化合物は、in vitroラット血小板凝集抑制作用試験において強力な活性を示した。なお、被験物質である化合物(1)-1~(1)-3は、いずれもω鎖の水酸基の立体化学がR体とS体のジアステレオマー混合物である。従って、該混合物から有効な活性体(一方のジアステレオマー)のみを分離して、同様に上記試験を実施すれば、活性は約2倍になる可能性がある。
(1)IC50値の測定
被験物質として本発明化合物(79、132及び263nmol/kgの3用量)、リマプロスト(陽性対照物質:79、263及び789nmol/kgの3用量)又は対照(0.26vol%DMSOを含む注射用水)を10mL/kgで、4~10週齢のHartley系雄性モルモットに単回経口投与し、4時間後に腹部大動脈より採血を行い、血小板凝集能を測定し、上記試験例1(3)と同様に、凝集抑制活性のIC50値(0.5μmol/LのADPで凝集を誘発)を算出した。
上記(1)の試験で算出したIC50を示す用量の化合物(1)-7(168nmol/kg)、化合物(1)-9(178nmol/kg)、化合物(1)-10(187nmol/kg)及びリマプロスト(266nmol/kg)を単回経口投与し、1、2、4、6、10、16及び24時間後に、上記試験例1(1)と同様に、モルモット腹部大動脈より採血して、血小板数を約60×104/μLにPPPで希釈したPRPを調製した(n=3~4)。
上記試験例1の(2)と同様に、Bornの方法に準じ、血小板凝集能の測定を行った。PRP 190μLをガラスキュベットに入れ、血小板凝集能測定装置に装着後、37℃で10分間インキュベートした。凝集剤としてADPを終濃度が0.5μmol/Lになるように10μL加え、凝集を惹起し、凝集の最大反応を測定した。
IC50算出時の対照群の最大凝集率と被験物質の最大凝集率より、対照群を0%とした時の被験物質の最大凝集抑制率を求めた。さらに、縦軸を最大凝集抑制率(%)、横軸を被験物質投与後の時間(時間)とした最大凝集抑制率の時間経過を表したグラフにおいて、各測定時間においてプロットした最大凝集抑制率の点をつないだ直線と横軸によって囲まれた部分の面積をAUCとして求めた。また、該グラフ上で最大凝集抑制率が0となる推定時間を凝集抑制が消滅する時間(抑制0時間)として求めた。
(1)被験物質の投与
被験物質として、本発明化合物又はリマプロスト(陽性対照物質)を原則0.263、0.789及び2.63nmol/kgでSlc:Wistar系雄性ラット(体重:約200~250g)の尾静脈内に、インフュージョンポンプ(model 11、Harvard Apparatus)を用いて毎分0.2mLの流速で10分間持続注入した。なお、対照群には1vol%DMSO-生理食塩液を同様に投与した(各群5~6匹)。
ラットをハロタン麻酔下で腹臥位に保定し、ヒーター(日本医化)で保温した。ラットの腰背部を剃毛、切開して脊椎を露出し、第5腰椎の椎弓を切除して馬尾神経を露出した。馬尾血流は、露出した馬尾神経に対して約1mm上部に垂直になるように固定した非接触型プローブ(LP-NC特型、ユニークメディカル)を介してレーザードップラー血流計(TBF-LN1、ユニークメディカル)を用いて、各被検物質の投与前から投与60分後まで測定した。なお、開創部には流動パラフィンを充てんし、露出した馬尾神経の乾燥を防止した。
得られたデータは1/400秒ごとにPowerLab8/30(登録商標、ML870、ADInstruments)を介してパーソナルコンピュータに取り込み、LabChart(登録商標、ADInstruments)を用いて解析した。解析時点は投与前(投与0分)、投与3、5、8、10、13、15、18、20、30、40、50及び60分後、または投与前(投与0分)、投与3、5、10、15、20、30、40、50及び60分後とし、各時点における10秒間の平均値を測定値とし、投与前値に対する変化率(%)を次式により求めた。
変化率(%)=(各時点における投与後の測定値 - 投与前の測定値)/投与前の測定値×100
さらに、各時点における対照群に対する変化率(%)の差〔Δ変化率(%)〕を次式により算出し、このΔ変化率の最大値を最大変化率とした。
Δ変化率(%)=各時点における各個体の変化率 - 対照群の変化率の平均値
被験物質の各用量における最大変化率から直線回帰式により、馬尾血流量が20%増加する用量(ED20値)を求め、リマプロストのED20値の活性を100とした時の各被験物質の相対活性(%)を算出した。
結果を表4に示す。本発明化合物は、ラット馬尾血流量試験において強力な活性を示した。
