Abstract: Intravitreal administration of a JNK-inhibitory peptide less than 150 amino acids in length, containing at least one D-amino acid, and having (a) a JNK-inhibitory sequence of at least any of SEQ ID NO: 1 and SEQ ID NO: 2, and (b) a transport sequence of at least any of SEQ ID NO: 3 and SEQ ID NO: 4 suppressed spermidine-induced retinal pigment epithelial damage, tunicamycin-induced photoreceptor cell damage, and laser-induced choroidal neovascularization. Thus, the JNK-inhibitory peptide of the present invention is useful for prophylaxis or therapy of a retinal disease. By the use of this JNK-inhibitory peptide, a drug and a method are provided which are capable of preventing or treating a retinal disease even by topical administration to the eye, and use of the JKN-inhibitory peptide for manufacturing the drug is also provided.
