  摘要：

  为了选择性增强二十碳五烯酸（EPA）和二十二碳六烯酸（DHA）的有益生物学作用，已经分别从EPA和DHA开始合成了链中含有硫或氧原子的许多多不饱和脂肪酸。这些酸的氧化降解导致相应的醛全-（Z）-3,6,9,12-十五碳烯醛和全-（Z）-3,6,9,12,15-十八碳烯醛。与DBU的反应分别将这些醛定量地转化为共轭异构体（2E，6Z，9Z，12Z）-十五碳烯醛和（2E，6Z，9Z，12Z，15Z）-十八碳烯醛。通过一系列反应将四种醛转化，所述反应包括还原成醇，卤化并用巯基酯取代成相应的含硫多不饱和脂肪酸酯。

  We found that putative metabolites of docosahexaenoic acid (DHA) are strong PPARgamma activators and potential antidiabetic agents. We designed DHA derivatives based on the crystal structure of PPARgamma, synthesized them and evaluated their activities in vitro and in vivo. The efficacy of 5E-4-hydroxy-DHA 2a as a PPARgamma activator was about fourfold stronger than that of pioglitazone. Further-more, the 4-keto derivative (10b) showed antidiabetic activity in animal models without producing undesirable effects such as obesity and hepatotoxicity. (C) 2004 Elsevier Ltd.

  To discover novel peroxisome proliferator-activated receptor gamma (PPAR gamma) agonists that Could be used as antidiabetic agents, we designed docosahexacnoic acid (DHA) derivatives (2 and 3), which have a hydrophilic substituent at the C(4)-position, based on the crystal structure of the ligand-binding pocket of PPAR gamma. These compounds were synthesized via iodolactolic as a key intermediate. We found that both DHA derivatives (2 and 3) showed PPAR gamma transactivation higher than, or comparable to, that of pioglitazone, which is a TZD derivative used as an antidiabetic agent. DHA derivatives related to these potent Compounds 2 and 3 were also synthesized to study structure-activity relationships. Furthermore, 4-OH DHA 2, which shows strong PPAR gamma transcriptional activity, was separated as an optically pure form. (c) 2005 Elsevier Ltd. All rights reserved.
