A pharmaceutical preparation efficaciously promotes tissue wound repair. The wound repair promoter according to the present invention includes at least one active ingredient selected from the group consisting of compounds represented by Formula (1), salts of the compounds, and hydrates of the compounds or the salts. In the formula, R1 and R2 are each, identically or differently, selected from hydrogen and a hydrocarbon group optionally having one or more substituents selected from the group consisting of halogens, —；COOR3, —；CONR32, —；COR3, —；CN, —；NO2, —；NHCOR3, —；OR3, —；SR3, —；OCOR3, —；SO3R3, and —；SO2NR32, where R3 is, identically or differently in each occurrence, selected from hydrogen and an optionally substituted aliphatic hydrocarbon group； and n represents an integer of 1 or more.
