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. The present invention also relates to a pharmaceutical composition containing the 4-oxoquinoline compound or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier; an integrase inhibitor, an antiviral agent, anti-HIV agent, and the like, which contains the 4-oxoquinoline compound or a pharmaceutically acceptable salt thereof as an active ingredient; an anti-HIV composition containing the 4-oxoquinoline compound or a pharmaceutically acceptable salt thereof, and one or more other kinds of anti-HIV activity substances as active ingredients; an anti-HIV agent containing the 4-oxoquinoline compound or a pharmaceutically acceptable salt thereof as an active ingredient, which is used for a multiple drug therapy with other anti-HIV agent(s), and the like.
摘要:
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.

An anti-HIV agent containing, as an active ingredient, a 4-oxoquinoline compound represented by the following formula [I] wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof. The compound of the present invention has 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 compound can become a more effective anti-HIV agent. Since the compound has high inhibitory activity specific for integrases, it can provide a safe pharmaceutical agent with a fewer side effects for human.

摘要:
An electric dust collector that does not need an exhaust fan or special equipment for preventing dust from flying off. An incinerator is formed on a building, and a smokestack is raised so that it is integrated with the wall of the incinerator. The smokestack is formed from metallic sheeting and lined with refractories. A beam is installed over the smokestack. The beam is electrically insulated using insulatores. A discharge electrode is suspended form the beam at the center of the smokestack. The discharge electrode has many needle-like discharge pins almost in its lower half part. The negative pole of a DC high-voltage power supply is connected with the discharge electrode, while the positive pole is grounded and connected with the metallic sheeting constituting the smokestack.

An equipment support structure capable of permitting the vertical arrangement or orientation of a damper spring to be readily carried out irrespective of the posture of setting of an equipment, A damper link which is pivotally moved depending upon the position of setting of an equipment is pivotally mounted at the proximal end thereof on one of the equipment and mount for supporting the equipment through dampers and a damper spring is provided between the damper link and the other of the mount and equipment for offsetting load applied from the equipment to the dampers and operatively connected to the damper ling so as to be pivotally moved in association with the damper link.
摘要:
A magnetic recording and/or reproducing device for recording information on a disc-like magnetic recording medium and/or reproducing the information from it, said magnetic recording and/or reproducing device having a pair of magnetic head members each composed of a magnetic head chip and a slide pad for slidably holding the disc-like magnetic recording medium at its both surfaces between the pair of magnetic head members under a predetermined contact pressure, wherein the slide pad is so disposed as to surround the magnetic head chip and the top portion of the magnetic head chip is so disposed as to protrude by a predetermined amount from a sliding contact surface between the slide pad and the disc-like magnetic recording medium. It makes possible by the magnetic recording and/or reproducing device of the above described type to obtain such a desirable state in which the disc-like magnetic recording medium can be steadily held in contact with the magnetic head chips, since the slide pads act primarily to minimize the warp of the disc-like magnetic recording medium and also the deformation of the disc-like magnetic recording medium which would result from a deviation in position of one or both of the magnetic head members relative to the disc-like magnetic recording medium.
