  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。
