Abstract

The present invention is to provide a novel compound (I) shown below, having the anti-virus activity, particularly the HIV integrase inhibitory activity, and a drug containing the same, particularly an anti-HIV drug, as well as a process and an intermediate thereof.

(wherein
Z 1 is NR 4 ; R 1 is hydrogen or lower alkyl; X is a single bond, a hetero atom group selected from O, S, SO, SO 2 and NH, or lower alkylene or lower alkenylene in which the hetero atom group may intervene; R 2 is optionally substituted aryl; R 3 is hydrogen, a halogen, hydroxy, optionally substituted lower alkyl etc; and R 4 and Z 2 part taken together forms a ring, to form a polycyclic compound, including e.g., a tricyclic or tetracyclic compound.
