Title:
NOVEL MYCOSPORINE-LIKE AMINO ACID
Document Type and Number:
WIPO Patent Application WO/2017/082144
Kind Code:
A1
Abstract:
The present invention provides a compound represented by formula (I), or a pharmaceutically acceptable salt or prodrug thereof. The present invention also provides: a composition which includes the compound represented by formula (I), or the pharmaceutically acceptable salt or prodrug thereof; and a cosmetic which includes said composition. (In formula (I): Q1 is oxygen, an amino acid residue, or an aminoalcohol, and, in cases when Q1 is an amino acid residue or an aminoalcohol, the amino acid residue or the aminoalcohol is bonded to the ring by nitrogen; and Q2 is oxygen, an amino acid residue, or an aminoalcohol, and, in cases when Q2 is an amino acid residue or an aminoalcohol, the amino acid residue or the aminoalcohol is bonded to the ring by nitrogen.)
