As a prostaglandin its used in livestock as an abortifacient.
Consequently it's pharmacology and or pharmacokinetics are entirely unrelated to DNP, a substance (currently listed as a pesticide/poison) that uncouples oxidative phosphorylation which squanders ATP production for the generation of heat.
To that end much of the THEORY behind the use of prostaglandins weight loss agents can be summarized if you review the "Princeton Metabolic Diet".
In brief, studies conducted in rodents and to some extent patients with metabolic syndrome revealed prostaglandins increased the catabolism of fatty acids in BAT (Brown Animal Fat) as a means of thermogenic regulation.
That means the energy in brown fat ONLY might could be used for entropic processes! Of course the PROBLEM is adults have very little BAT.
Some researchers looked at increasing COX-2 (a prostaglandin precursor) activity in genetically engineered knock out MICE and discovered they not only converted more WAT into BAT but also "lost more" fat!
But.....
