An aminothiophene derivative is provided to decrease ischemic apoptosis, thereby being used as a composition for preventing and treating ischemic diseases mediated by the ischemic apoptosis or for protecting organs. A composition for preventing or treating ischemic diseases comprises an aminothiophene derivative represented by a formula(1) or (2), or a pharmaceutically acceptable salt thereof as an effective ingredient, wherein the ischemic disease is cerebral ischemia, cardiac ischemia, diabetic cardiovascular diseases, cardiac failure, cardiac hypertrophy, retinal ischemia, ischemic colitis, ischemic acute renal failure, stroke, cerebral wound, Alzheimer's disease, Parkinson's disease, hypoxia in newborn, glaucoma and diabetic neuropathy. In the formulae, R^1 is H, CO2R^2, CH2OR^2, CONR^2R^3, or a group(1); each R^2 and R^3 is independently H, or C1-6 linear or branched alkyl, or halogen or hydroxy substituted alkyl; B is H, phenyl, or C1-3 alkyl or halogen substituted phenyl; n is an integer from 0 to 2; Y is S, O, SO or SO2; Z is H, halogen, NO2, NH2, C1-3 linear or branched alkyl or OR^4; R^4 is H or C1-3 linear or branched alkyl; and A is CH, N or N-O. Further, the ischemic diseases are selected from cerebral ischemic damage, Ischemic Heart Failure, cardiac failure, retinal ischemia or Alzheimer's disease.
