Piperazinealkanol ester derivatives of indomethacin were prepared and tested for inhibitory activities against 5-lipoxygenase (5-LO) and cyclooxygenase (CO). They inhibited 5-hydroxyeicosatetraenoic acid (5-HETE) formation by the cytosol of guinea pig polymorphonuclear leukocytes and thromboxane B2 (TXB2) formation by washed rabit platelet suspension. Of the test compounds, 2-[4-(2-hydroxyethyl)-1-piperazinyl]-1-phenylethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-3-indolylacetate dimaleate (II-8) was found to be the most active dual inhibitor of 5-LO and CO, and its inhibitory potency was higher than that of 2-[4-(3-hydroxypropyl)-1-piperazinyl]-ethyl [1-(4-chlorobenzoyl)-5-methoxy-2-methyl]-3-indolylacetate (CR-1015) (I), the lead compound.
已经制备并测试了吲哚美辛的哌嗪烷醇酯衍生物对5-脂肪氧化酶(5-LO)和环氧合酶(CO)的抑制活性。它们抑制了豚鼠多形核白细胞的细胞质中5-羟基二十碳四烯酸(5-HETE)的形成以及洗涤兔血小板悬浮液中血栓烷B2(TXB2)的形成。在测试化合物中,2-[4-(2-羟乙基)-1-哌嗪基]-1-苯乙基 1-(4-氯苯甲酰)-5-美氧基-2-甲基-3-吲哚乙酸二马来酸盐(II-8)被发现是最活跃的5-LO和CO的双重抑制剂,其抑制效力高于领先化合物2-[4-(3-羟丙基)-1-哌嗪基]-乙基[1-(4-氯苯甲酰)-5-美氧基-2-甲基]-3-吲哚乙酸(CR-1015)(I)。
