The present invention provides compounds which specifically inhibit FXa, which are effective when orally administered and which are useful as a safe medicine for the prevention or treatment of diseases caused by thrombus or infarction.
Compounds of this invention are piperazinones of the formula:
wherein R1 is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group; the ring A is an optionally substituted divalent nitrogen-containing heterocyclic group, in addition to being substituted by the group of the formula:
and the group of the formula:
Y is an optionally substituted divalent hydrocarbon group or an optionally substituted divalent heterocyclic group; X is a direct bond or an optionally substituted alkylene chain; Z is (1) an amino group substituted with an optionally substituted hydrocarbon group, (2) an optionally substituted imino group or (3) an optionally substituted nitrogen-containing heterocyclic group; provided that when X is a direct bond and Z is an optionally substituted 6-membered nitrogen-containing aromatic heterocyclic group, Y is an optionally substituted divalent hydrocarbon group or an optionally substituted divalent unsaturated heterocyclic group; or a salt thereof.
本发明提供了一种化合物,该化合物特异性地抑制FXa,口服给药有效,并且用作预防或治疗由血栓或梗死引起的疾病的药物是安全的。本发明的化合物是哌嗪酮的公式:
其中R1是可选地取代的烃基或可选地取代的杂环基;环A是除了被公式:的基团取代的之外的可选地取代的二价含氮杂环基:
和公式的基团:
Y是可选地取代的二价烃基或可选地取代的二价杂环基;X是直接键或可选地取代的亚烷基链;Z是(1)与可选地取代的烃基取代的氨基,(2)可选地取代的亚氨基或(3)可选地取代的含氮杂环基;当X是直接键并且Z是可选地取代的6-成员含氮芳香杂环基时,Y是可选地取代的二价烃基或可选地取代的二价不饱和杂环基;或其盐。
