  Synthesis and dual biological effects of hydroxycinnamoyl phenylalanyl/prolyl hydroxamic acid derivatives as tyrosinase inhibitor and antioxidant

  摘要：

  We previously reported that caffeoyl-amino acidyl-hydroxamic acid (CA-Xaa-NHOH) acted as both a good antioxidant and tyrosinase inhibitor, in particular when caffeic acid was conjugated with proline or amino acids having aromatic ring like phenylalanine. Here, various hydroxycinnamic acid (HCA) derivatives were further conjugated with phenylalanyl hydroxamic acid and prolyl hydroxamic acid (HCA-Phe-NHOH and HCA-Pro-NHOH) to study the structure and activity relationship as both antioxidants and tyrosinase inhibitors. When their biological activities were evaluated, all HCA-Phe-NHOH and HCA-Pro-NHOH exhibited enhanced antioxidant activity compared to HCA alone. Moreover, derivatives of caffeic acid, ferulic acid, and sinapic acid inhibited lipid peroxidation more efficiently than vitamin E analogue (Trolox). In addition, derivatives of caffeic acid and sinapic acid efficiently inhibited tyrosinase activity and reduced melanin content in melanocytes Mel-Ab cell. (C) 2012 Elsevier Ltd.
