2,3-Dinorprostaglandins (dinor-PGs) have been regarded as beta-oxidation products of arachidonic-acid-derived prostaglandins, but their biological activities in mammalian cells remain unclear. On the other hand, C18 polyunsaturated fatty acids (PUFAs), such as gamma-linolenic acid (GLA), have various biological activities, and dinor-PGs are speculated to be biosynthesized from GLA. Here, we synthesized dinor-PGs that may possibly be derived from GLA and examined their activities towards peroxisome proliferator-activated receptors (PPARs). Dinor-PGD(1) (1) and its epimer 13-epi-dinor-PGD(1) (epi-1) were found to be dual agonists for PPAR alpha/gamma, whereas PGD(2) derived from arachidonic acid is selective for PPAR gamma. Thus, GLA-derived dinor-PGs may have unique biological roles. (C) 2013 Elsevier Ltd. All rights reserved.
