| Description | ent-11α-Hydroxy-15-oxokaur-16-en-19-oic acid is an anti-melanin synthesis tyrosinase inhibitor, which can be isolated from Pteris fern. ent-11α-Hydroxy-15-oxokaur-16-en-19-oic acid regulates the melanogenesis transcription factor microphthalmia-associated transcription factor (MITF). The 11α-OH, 15-oxo and 16-en moieties of ent-11α-Hydroxy-15-oxokaur-16-en-19-oic acid are key fragments that inhibit melanin synthesis. The 19-COOH moiety has been implicated in the inhibition of cytotoxicity associated with 11α-OH KA and related compounds[1]. |
