A series of cinnamylindoline derivatives were synthesized, and their factor Xa (FXa) inhibitory activities and selectivity over trypsin were evaluated. Among them, some novel derivatives showed potent FXa inhibitory activities and good selectivity over trypsin. Especially, (E)-2-5-[1-(acetimidoyl)piperidin-4-yloxy]-2-[2-(5-amidino-2-hydroxyphenyl)ethen-1-yl]indolin-1-ylsulfonyl}acetic acid (22f) having 2-hydroxycinnamyl moiety exhibited the most potent FXa inhibitory activity in vitro. Furthermore, 22f also exhibited potent anticoagulant activities in vitro.
合成了一系列肉桂基
吲哚衍

蛋白酶的选择性。其中一些新型衍
生物表现出强效的FXa抑制活性及优良的选择性,尤其是(E)-2-5-[1-(乙酰
氨基)
哌啶-4-氧基]-2-[2-(5-

乙烯-1-基]
吲哚-1-基磺酰}
乙酸(22f)具有2-羟基肉桂基结构,在体外表现出最强的FXa抑制活性。此外,22f在体外也表现出强效的抗凝活性。
