Improved Synthesis of (<i>E</i>)-12-Nitrooctadec-12-enoic acid, a Potent PPARγ Activator. Development of a “Buffer-Free” Enzymatic Method for Hydrolysis of Methyl Esters
nitro-fatty acids, acting as partial agonist of PPARγ, are able to lower the insulin and glucose levels without the side effects associated with common antidiabetic drugs. (E)-12-Nitrooctadec-12-enoic acid, a potent activator of this peroxisome receptor, was synthesized in a very efficient sequence via a Henry−retro-Claisen ring fragmentation, followed by a novel enzymatic cleavage of methyl esters. The latter

Okinawan coral Clavularia viridis is also biosynthesized by the unrelated Caribbean coral, Pseudoplexaura porosa, indicating that the biosynthesis of 5 may be widespread in coral. The biogenesis of preclavulone-A from arachidonic acid occurs by lipoxygenation at C(8), migration of oxygen from C(8) to C(9) and ring closure, in a process (marine pathway) which contrasts sharply with the mammalian (endoperoxide)
