摘要:
In the present article, tyrosinase inhibition studies on fifteen diterpenoid alkaloids, with lycoctonine skeleton, and their semisynthetic derivatives 1 - 15 and six napelline-type compounds 16 - 21 are discussed. Their structure - activity relationship for tyrosinase inhibition is also discussed. These activities were compared with two referenced tyrosinase inhibitors, kojic acid and L-mimosine. The study showed that lappaconitine HBr ( 1) is the most potent member of the series ( IC50 = 13.30 mu M).
