摘要

Provided is a novel Eg5 inhibitor which contains, as an active ingredient, a nitrogen-containing heteropolycyclic compound such as a carbazole derivative or a carboline derivative.  The novel Eg5 inhibitor contains, as an active ingredient, a nitrogen-containing heteropolycyclic compound represented by general formula (I) or a pharmacologically acceptable salt thereof.  In general formula (I), the linkages a-b and c-d are each a single or double bond; Q1 to Q4 are each a nitrogen atom or -C(X)=; X and Y1 to Y4 are each a hydrogen atom, an alkyl group, an aralky group, an aryl group, a heterocyclic group, a hydroxyl group, an alkoxy group, a carboxyl group, a halogen atom, or the like; and Z is a hydrogen atom, an alkyl group, or the like.
