Tyrosinase inhibitors from Calceolaria integrifolia s.l.: Calceolaria talcana aerial parts.
    Journal of agricultural and food chemistry, 2013, May-08, Volume: 61, Issue:18

    As a defense mechanism of the aerial parts of Calceolaria talcana (Calceolariaceae; formerly Scrophulariaceae) against herbivore offenses and insect pest attack, diterpenoids, triterpenoids, phenylethanoids, flavonoids, and iridoids are rapidly accumulated along the aerial parts, resulting in a unique natural biopesticide complex from this plant. In addition to verbascoside a series of known compounds were screened for their inhibitory activity against mushroom tyrosinase and protease enzymes. Ethyl acetate and n-hexane extracts, together with cyclopropyl-7,15-ent-pimaradiene (1), abietatriene (2), ursolic acid (3), α-lupeol (4), β-sitosterol (5), 2-hydroxy-3-(1,1-dimethylallyl)-1,4-naphthoquinone (6), α-dunnione (7), verbascoside (8), martynoside (9), and some known model compounds proved to be inhibitors of oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) catalyzed by tyrosinase (EC 1.14.18.1) with an IC50 between 10.0 and 200 ppm or μM, respectively, suggesting that phenolic moieties in the molecules assayed are important for the activity.
