ELASTIN PRODUCTION-ENHANCING AGENTS

摘要

An objective of the present invention is to provide novel useful elastin production-enhancing agents that have a remarkable ability to enhance elastin production. The present invention provides elastin production-enhancing agents that include at least one component selected from the group consisting of the peptide Leu-Glu-His-Ala (formula I; SEQ ID NO:1), derivatives of the peptide, and salts thereof. The present invention also provides elastin production-enhancing agents that include at least one component selected from the group consisting of peptides which include a conservative substitution, deletion, and/or addition of one or more amino acids in the amino acid sequence of formula I that retain an ability to enhance elastin production in cells; derivatives of such peptides; and salts thereof.
