PROBLEM TO BE SOLVED: To provide use of a protein kinase inhibitor for treating a disease strongly associated with JNK signaling. Use of a chimeric peptide comprising at least one first domain and at least one second domain covalently linked for the preparation of a pharmaceutical composition for treating cystitis. And the first domain comprises a trafficking sequence, the second domain comprises a JNK inhibitor sequence comprising a length of less than 150 amino acids, and the chimeric peptide comprises all of the SEQ ID NO: 11. Uses that include the D amino acid sequence.
