  Synthesis and antioxidant evaluation of isochroman-derivatives of hydroxytyrosol: Structure–activity relationship

  摘要：

  Isochroman-derivatives of the natural olive oil phenol hydroxytyrosol (HT) have been synthesised via Oxa-Pictet-Spengler reaction in high yields. Lipophilicity and antioxidant activity were determined to establish the structure-activity relationship of isochromans compared to HT, BHT and alpha-tocopherol. Antioxidant capacity was tested in two different media: bulk oils, using the Rancimat test, and brain homogenates, by measuring malondialdehyde (MDA) levels as a lipoperoxidation biomarker. In addition, other antioxidant assays (FRAP, ABTS and ORAC) were carried out. Rancimat and MDA results show that antioxidant activity was related with lipophilicity, directly in brain homogenates and inversely in the oils, in agreement with the polar paradox. Free o-diphenolic groups positively determined the activity in the oils, whereas reducing and radical-scavenging activities were related to the number of free hydroxyl moieties. BHT and a-tocopherol showed lower antioxidant activity than isochromans and HT. We conclude that HT-isochromans present significant potential as bioactive compounds. (C) 2014 Elsevier Ltd.

  A facile method to obtain an isochromanic structure was achieved by the oxa-Pictet-Spengler reaction using 2-(3',4'-dihydroxy)phenylethanol as starting material. The reaction was performed in very mild conditions on a series of carbonylic compounds. Yields were always satisfactory. (C) 2001 Elsevier Science Ltd. All rights reserved.
