  Synthesis of trans-caffeate analogues and their bioactivities against HIV-1 integrase and cancer cell lines

  摘要：

  Forty caffeate analogues were synthesized via a convenient method starting from vanillin with moderate to good yields. The testing of biological activity of these compounds against HIV-1 integrase indicates that four compounds: bornyl caffeate, bornyl 2-nitrocaffeate, 5-nitrocaffeic acid and 5-nitrocaffeic acid phenethyl ester (5-nitroCAPE) possess a good HIV integrase inhibitory activity, IC50 19.9, 26.8, 25.0 and 13.5 mu M, respectively. Twelve caffeate analogues were tested by MTT assay on growth of human hepatocellular carcinoma BEL-7404, human breast MCF-7 adenocarcinoma, human lung A549 adenocarcinoma and human gastric cancer BCG823 cell lines, respectively. And the best result is IC50 5.5 mu M for CAPE against BEL-7404. (C) 2008 Elsevier Ltd. All rights reserved.

  of the enzyme xanthine oxidase (XO) with radical scavenging properties hold promise as novel agents against reperfusion injuries after ischemic events. By suppressing the formation of damaging reactive oxygen species (ROS) by XO or scavenging ROS from other sources, these compounds may prevent a buildup of ROS in the aftermath of a heart attack or stroke. To combine these two properties in a single molecule
