Abstract: A compound represented by formula (1) or salt thereof and a production intermediate thereof are created. The compound exhibited an excellent antioxidation action in a microsome lipid peroxidation measuring system using a rat liver microsome. Therefore, the compound or salt thereof is useful as an antioxidant. The present invention also provides use of a compound represented by the formula (1) or a pharmaceutically acceptable salt thereof for production of an antioxidant.

Abstract: An object of the present invention is to create a novel indazole derivative having a spiro ring structure in a side chain, which is useful as a pharmaceutical, and to find a new pharmacological activity of the derivative. The present invention compound is represented by the general formula [I] and has an excellent Rho kinase inhibitory activity. In the formula, the ring X represents a benzene ring or a pyridine ring; R1 and R2 represent halogen, H, OH, alkoxy, cycloalkyloxy, aryloxy, alkyl, cycloalkyl or the like; R3 represents halogen, H or the like; R4 and R5 represent halogen, H or the like; R6 and R7 represent H, alkyl or the like; and m, n, p and q represent an integer of 0 to 3. In this connection, each group may have a substituent.

Abstract: There are provided compounds represented by the following general formula (I): [where R1 is 5-methylpyridin-2-yl, p-tolyl or mesityl, R2 is one of the following general formulas (II)-(IX): (where R3 is C1-C4 alkyl, R4 is H or C1-C4 alkyl, R5 is H, 3-pyridylmethyl or 4-pyridylmethyl, and R6 is 2,4-dihydroxybenzyl, 3-pyridylmethyl or 4-pyridylmethyl), or when R1 is mesityl, R2 is the following formula (X)], and pharmaceutically acceptable salts thereof. The compounds exhibit pruritus-inhibiting action, and are useful for prevention or of itching and pruritus caused by reaction against insect-inflicted wounds, reaction against environmental allergens, skin infections or external parasite infections, or caused to renal dialysis patient.
