Abstract: A pharmaceutical agent having an anti-HIV action, particularly, a pharmaceutical agent having an integrase inhibitory action, is provided. The present invention relates to a quinolizinone compound represented by the following formula [I] wherein each symbol is as defined in the specification, a pharmaceutically acceptable salt thereof, and an anti-HIV agent containing same as an active ingredient. The compound of the present invention has an HIV integrase inhibitory action and is useful as an anti-HIV agent for the prophylaxis or therapy of AIDS. Moreover, by a combined use with other anti-HIV agents such as protease inhibitors, reverse transcriptase inhibitors and the like, the compounds can become a more effective anti-HIV agent. Since the compound has a high inhibitory activity specific for integrases, the compound can provide a safe pharmaceutical agent for human with a fewer side effects.

Abstract: Provision of a compound having an anti-HIV activity, particularly an integrase inhibitory activity. A 4-oxoquinoline compound represented by the following formula [I] or a pharmaceutically acceptable salt thereof: wherein each symbol is as defined in the specification.

Abstract: The present invention relates to a nitrogen-containing fused ring compound represented by the following formula [I] wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof, and an anti-HIV agent containing such compound. The compound of the present invention has an HIV integrase inhibitory activity, and is useful as an agent for the prophylaxis or treatment of AIDS, or as an anti-HIV agent. In addition, by the combined use with other anti-HIV agents such as a protease inhibitor, a reverse transcriptase inhibitor and the like, it can be a more effective anti-HIV agent. Because it shows integrase-specific high inhibitory activity, the compound can be a pharmaceutical agent safe on human body, which causes only a fewer side effects.
