专利名称:脂环族磷脂酶a的制作方法
本涉及是1993年6月16日递交的共同未决美国专利申请08/079,072的部分继续申请。
本发明涉及的是具有磷脂酶A2(PLA2)抑制剂活性的化合物。PLA2是一种钙依赖性酶,它切割磷脂的sn-2酰基键,产生花生四烯酸和溶血磷脂(H.Van den Bosch et al.in Biochim.Biophys.Acta 1980,604,191)。这两种反应均可用作生物合成炎性介质的起始点。花生四烯酸一旦释放,即被环氧酶和脂氧酶等酶迅速代谢,产生熟知的发炎介质前列腺素和白细胞三烯(leukotriene)(P.Davies and D.E.MacIntyre in"InflammationBasic Principles and Clinical Correlates",2nd Ed.,J.I.Callin,I.M.Goldstein and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 7;B.K.Lam and K.F.Austen in "InflammationBasic Principles and Clinical Correlates",2nd Ed.J.I.Gallin,I.M.Goldstein,and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 8)。溶血磷脂可被某些类型的细胞利用,产生血小板激活因子(PAF),即另一种有效的发炎介质(G.A. Zimmerman,S.M.Prescott,and T.M McIntyre in"InflammationBasic Principles and Clinical Correlates",2nd Ed.J.I.Gallin,I.M.Goldstein,and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 9)。PLA2在炎性疾病中的作用已有描述(P.Vadas and W.Pruzanski in Laboratory Investigation,1986,55,391-404;W.Pruzanski,E.Bogoch,M.Wloch,and P.Vadas in Journal of Rheumatology,1991,18,117-119;W.Pruzanski,K.Scott,G.Smith,I.Rajkovic,E.Stefanski,and P.Vadas in Inflammation,1992,16,451-457;W.Pruzanski,D.W.Wilmore,A.Suffredini,G.D.Martich,A.G.D.Hoffman,I.L.Browning,E.Stefanski,B.Sternby,and P.Vadas in Inflammation,1992,16,561-570;J.M.Gronroos and T.J.Nevalainen in Digestion,1992,52,232-236)。由于PLA2是导致前列腺素和白细胞三烯及PAF释放途径中的关键酶,因此抑制该酶也就成为预防、消除或改善炎症的一种合适方法。

本涉及是1993年6月16日递交的共同未决美国专利申请08/079,072的部分继续申请。
本发明涉及的是具有磷脂酶A2(PLA2)抑制剂活性的化合物。PLA2是一种钙依赖性酶,它切割磷脂的sn-2酰基键,产生花生四烯酸和溶血磷脂(H.Van den Bosch et al.in Biochim.Biophys.Acta 1980,604,191)。这两种反应均可用作生物合成炎性介质的起始点。花生四烯酸一旦释放,即被环氧酶和脂氧酶等酶迅速代谢,产生熟知的发炎介质前列腺素和白细胞三烯(leukotriene)(P.Davies and D.E.MacIntyre in"InflammationBasic Principles and Clinical Correlates",2nd Ed.,J.I.Callin,I.M.Goldstein and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 7;B.K.Lam and K.F.Austen in "InflammationBasic Principles and Clinical Correlates",2nd Ed.J.I.Gallin,I.M.Goldstein,and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 8)。溶血磷脂可被某些类型的细胞利用,产生血小板激活因子(PAF),即另一种有效的发炎介质(G.A. Zimmerman,S.M.Prescott,and T.M McIntyre in"InflammationBasic Principles and Clinical Correlates",2nd Ed.J.I.Gallin,I.M.Goldstein,and R.Snyderman,Eds,Raven Press,LtdNew York,1992;Chapter 9)。PLA2在炎性疾病中的作用已有描述(P.Vadas and W.Pruzanski in Laboratory Investigation,1986,55,391-404;W.Pruzanski,E.Bogoch,M.Wloch,and P.Vadas in Journal of Rheumatology,1991,18,117-119;W.Pruzanski,K.Scott,G.Smith,I.Rajkovic,E.Stefanski,and P.Vadas in Inflammation,1992,16,451-457;W.Pruzanski,D.W.Wilmore,A.Suffredini,G.D.Martich,A.G.D.Hoffman,I.L.Browning,E.Stefanski,B.Sternby,and P.Vadas in Inflammation,1992,16,561-570;J.M.Gronroos and T.J.Nevalainen in Digestion,1992,52,232-236)。由于PLA2是导致前列腺素和白细胞三烯及PAF释放途径中的关键酶,因此抑制该酶也就成为预防、消除或改善炎症的一种合适方法。
