The present invention provides a urea derivative or a salt thereof, which is useful as a therapeutic agent for thrombosis. The derivative is represented by Formula (I):
wherein Cy is an aromatic hydrocarbon group which may be substituted or an aromatic heterocyclic group which may be substituted; R
1
is a hydrogen atom or a hydrocarbon group which may be substituted; V is —C(O)—, —S(O)—, or —S(O)
2
—; W is —N(R
2
)—, —O—, or a bond (wherein R
2
is a hydrogen atom or a hydrocarbon group which may be substituted); X is alkylene which may be substituted; Y is —C(O)—, —S(O)—, or —S(O)
2
—; Z is a bond, a chain hydrocarbon group which may be substituted, or —N═; ring A is a non-aromatic nitrogen-containing heterocyclic ring which may be substituted; ring B is a nitrogen-containing heterocyclic ring which may be substituted; and
[Chemical formula 2]
,
are each independently a single bond or a double bond; provided that R
1
may be bonded to R
2
to form a non-aromatic nitrogen-containing heterocyclic ring and that R
2
may be bonded to a substituent of X to form a non-aromatic nitrogen-containing heterocyclic ring which may be substituted.
本发明提供一种尿素衍生物或其盐,其作为治疗血栓症的治疗剂是有用的。该衍生物由公式(I)表示:其中,Cy是芳香族羟基烃基或芳香族杂环基,可以被取代;R1是氢原子或可以被取代的碳氢基团;V是-C(O)-,-S(O)-或-S(O)2-;W是-N(R2)-,-O-或键(其中R2是氢原子或可以被取代的碳氢基团);X是可以被取代的烷基;Y是-C(O)-,-S(O)-或-S(O)2-;Z是键,可以被取代的链烃基团或-N═;环A是非芳香族含氮杂环环,可以被取代;环B是含氮杂环环,可以被取代;而[化学式2]都是单键或双键;但是,R1可以与R2连接形成非芳香族含氮杂环环,而R2可以与X的取代基连接形成可以被取代的非芳香族含氮杂环环。
