ABSTRACT:
It was found out that the nitrogen-containing heterocyclic derivative represented by the formula (I) specifically binds to a receptor of NR1/NR2B, and is used as a NR2B receptor antagonist.A compound represented by:wherein Z is N or CR1, A1is a nitrogen-containing aromatic monocyclic group which is optionally substituted, a nitrogen-containing aromatic fused cyclic group which is optionally substituted etc., A2is an aromatic hydrocarbon cyclic group or an aromatic heterocyclic group, each optionally having a substituent, R1, R2, Ra, Rb, Rcand Rdare each independently hydrogen, hydroxy, etc., w is 2 or 3, t is 1 or 2, X is —(CR3R4)m-, —CO(CR3R4)n-, —CONR5(CR3R4)n- etc., m is an integer of 1 to 4, n is an integer of 0 to 4, R3and R4are each independently hydrogen, halogen, hydroxy etc., and R5is hydrogen or lower alkyl,or a pharmaceutically acceptable salt, or a solvate thereof.
