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 Z1 is NR4; R1 is hydrogen or lower alkyl; X is a single bond, a hetero atom group selected from O, S, SO, SO2 and NH, or lower alkylene or lower alkenylene in which the hetero atom group may intervene; R2 is optionally substituted aryl; R3 is hydrogen, a halogen, hydroxy, optionally substituted lower alkyl etc; and R4 and Z2 part taken together forms a ring, to form a polycyclic compound, including e.g., a tricyclic or tetracyclic compound.

Abstract: The present invention features compounds that are prodrugs of HIV integrase inhibitors and therefore are useful in the inhibition of HIV replication, the prevention and/or treatment of infection by HIV, and in the treatment of AIDS and/or ARC.

Abstract: A composition having BACE 1 inhibitory activity containing a compound represented by the general formula (I): wherein ring A is an optionally substituted carbocyclic group or an optionally substituted heterocyclic group; E is lower alkylene; X is S, O, or NR?; R1 is a hydrogen atom or lower alkyl; R2a, R2b, R3a, R3b, R4a and R4b is each independently a hydrogen atom, halogen, or hydroxy etc.; n and m are each independently an integer of 0 to 3; n+m is an integer of 0 to 3; R5 is a hydrogen atom or substituted lower alkyl; its pharmaceutically acceptable salt, or a solvate thereof.

Abstract: The invention relates to tetrahydropyridinyl and dihydropyrrolyl compounds of Formula (I): and pharmaceutically acceptable salts, prodrugs, or solvates thereof, wherein X, Y, Z, R1, R2, m, and n are defined as set forth in the specification. The invention is also directed to the use of compounds of Formula (I) to treat a disorder responsive to the blockade of calcium channels, and particularly N-type calcium channels. Compounds of the present invention are especially useful for treating pain.

Abstract: A tablet characterized by comprising 5-methyl-1-phenyl-2-(1H)-pyridone as the main ingredient and, based on the main ingredient, 10 to 50 wt. % excipient, 5 to 40 wt. % disintegrator, 1 to 10 wt. % binder, 0.5 to 5 wt. % lubricant, 2 to 6 wt. % coating basis, and 0.05 to 3 wt. % light-shielding agent, wherein the odor or bitterness of the 5-methyl-1-phenyl-2-(1H)-pyridone is masked and the light stability is improved.

Abstract: Provided are a humanized monoclonal antibody against PcrV or a part thereof, and a pharmaceutical composition containing the same as an active ingredient, as an effective means for therapy of infection, particularly infection with Pseudomonas aeruginosa. Concretely, the humanized monoclonal antibody of the present invention has an excellent inhibitory activity on the cytotoxicity with respect to a target cell of Pseudomonas aeruginosa. Also, the humanized monoclonal antibody of the present invention has a high affinity for PcrV.

Abstract: Disclosed is a method for producing a hydroxylated form of a compound having an adamantane skeleton, which is useful as an intermediate for functional resins and pharmaceutical products, with high yield and at low cost. Specifically, a hydroxylated form of a compound having an adamantane skeleton can be obtained by using cytochrome P450. More specifically, an N-(5-hydroxy-2-adamantyl)-benzamide derivative can be produced by hydroxylating an N-(2-adamantyl)-benzamide derivative.

Abstract: The invention provides a novel means for the administration of a therapeutically effective ingredient in the form of a rectally applicable medicament capsule, in which the otherwise unavoidable extreme variation in the absorbability of the effective ingredient among the individuals rectally treated with the capsules is minimized. It has been unexpectedly found that, when the effective ingredient is contained in the capsule in the form of a liquid medicine, the osmotic pressure of the liquid content plays a very essential role in the absorption of the effective ingredient through the rectum and the variation in the absorbability of the effective ingredient among the individuals can be minimized when the osmotic pressure of the liquid content is substantially higher than the osmotic pressure of the rectal fluid with which the capsules are contacted.
