Abstract: Compounds represented by formula (I), compounds of the less-polar group of two groups of diastereomers in which the carbon atom indicated by * in formula (II) is an asymmetric carbon atom, salts of the compounds, and solvates of the compounds or salts. The compounds have Nrf2 activating action.

Abstract: A compound having Nrf2-activating action is provided. The compound is represented by formula (I), a salt of the compound, or a solvate of the compound or salt: wherein R1a and R1b are identical or different and represent a hydrogen atom, an alkyl group, or a halogen atom; R2 represents an optionally substituted group derived from a heterocycle, and the heterocycle represents thiophene, furan, pyrrole, thiazole, or a fused ring including any of these heterocycles; R4 and R5 are identical or different and represent a hydrogen atom or an optionally substituted alkyl group, or R4 and R5 bind with each other to form —NH—CH—N—; R6 represents an optionally substituted alkyl group; A1, A2, A3, and A4 are identical or different and represent CH or N wherein the number of N is 1 or less; and Z represents a hydrogen atom or a halogen atom.

Abstract: The main object of the present invention is to provide a novel compound which has a VEGF receptor tyrosine kinase inhibitory activity and is useful as an active ingredient for the treatment of diseases accompanying angiogenesis or edema, for example, age-related macular degeneration or the like. The present invention includes, for example, an alkynyl indazole derivative represented by the following general formula (I), a pharmaceutical acceptable salt thereof, and a medicine containing thereof.
