摘要:
Novel amide derivatives characterized in that, in N({[4-(substituted thiazol-4-yl)phenyl]carbamoyl}methyl)amide derivatives, the N atom in the amido group carries an aryl or heteroaryl substituent (i.e., an aromatic ring group) directly attached thereto. Because of having an excellent anti-herpesviral activity, these amide derivatives are useful as drugs and antiviral agents, in particular, preventives or remedies for various diseases caused by the infection with herpesviruses, more specifically, various herpesvirus infections such as pox (blister) caused by the infection with varicella zoster virus, herpes zoster caused by the recurrent infection with latent varicella zoster virus, herpes labialis and herpes encephalitis caused by the infection with HSV-1 and genital herpes caused by the infection with HSV-2.
摘要:
A process for producing azulene derivatives useful as Na+-glucose cotransporter inhibitor easily and simply in high yield at a low cost which is industrially advantageous and excellent in environmental protection, characterized by subjecting at least one compound selected from among specific penta- and tetraacyl precursors of the azulene derivatives and salts of the precursors to reduction and deblocking to obtain a C-glycoside compound; and useful intermediates obtained in the above process.
摘要:
A 2-phenylthiophene derivative represented by the following general formula (I) or a salt thereof, characterized by comprising a thiophene ring substituted by a carboxy group, etc. and a benzene ring having both of an electron-attracting group, e.g., a cyano group, and an electron-donating group, e.g., a substituted alkoxy group. (I) The compound is satisfactory in xanthine oxidase inhibitory activity and uric acid lowering activity and has no structure derived from any nucleic acid. The compound hence has an advantage that it is safer and more effective than conventional compounds. The compound is useful as a therapeutic or preventive agent for hyperuricemia, gout, inflammatory intestinal diseases, diabetic nephropathy, diabetic retinopathy, etc.
摘要:
Triazole derivatives which have a glycine transporter inhibitory activity and are useful as drugs; and novel triazole derivatives. Because of having an excellent glycine transporter inhibitory activity, the above triazole derivatives are useful as remedies.
摘要:
A 2-phenylpyridine derivative represented by the following general formula (I) or a salt thereof. The compounds have satisfactory xanthine oxidase inhibitory activity and uric acid-lowering activity and are useful as a therapeutic or preventive agent for hyperuricemia, gout, inflammatory intestinal diseases, diabetic nephropathy, diabetic retinopathy, etc. [The symbols in the formula have the following meanings: R1: H, etc.; R2: -CO2H, etc.; R3 and R4: H, etc.; R5: -CN, etc.; R6: H, etc.; X: -O-, -N(R8)-, or -S-; (provided that the groups represented by R5 and -X-R7 are bonded in a meta position or the para position to the pyridyl group) R8: H, etc.; R7: C1-8 linear or branched alkyl, etc.; Y: a bond, etc.; and R9, R10, and R11: H, etc. (provided that when X is -N(R8)-, then R8 may be bonded to R7 to form a nitrogenous saturated heterocycle in cooperation with the adjacent nitrogen atom).]
