| 摘要 |
The present invention relates to a peptide having the activity of insulin like growth factor-1 (IGF-1) and derived from IGF-1, a composition for improving skin conditions or treating a periodontal disease comprising the peptide. The IGF-1 mimicking peptides of this invention have identical functions or actions to natural-occurring IGF-1 and much better stability and skin permeation than natural-occurring IGF-1. In these connections, the composition comprising the peptides of this invention can exhibit excellent efficacies on the treatment, prevention and improvement of diseases or conditions demanding IGF-1 activities. In addition, the peptides of this invention can be advantageously applied to pharmaceutical compositions, quasi-drugs and cosmetics.
