The concept of dual PPARα/γ activation was originally proposed as a new approach for the treatment of the metabolic syndrome. However, recent results indicated that PPARα as well as PPARγ activation might also be beneficial in the treatment of inflammatory diseases and cancer. We have recently identified aminothiazole-featured pirinixic acids as dual 5-lipoxygenase (5-LO) and microsomal prostaglandin E2 synthase-1 (mPGES-1) inhibitors. Here we present the structure-activity relationship of these aminothiazole-featured pirinixic acids as dual PPARα/γ agonists and discuss their advantages with their potential as dual 5-LO/mPGES-1 inhibitors in inflammatory and cancer diseases. Various pirinixic acid derivatives had already been identified as dual PPARα/γ agonists. However, within this series of aminothiazole-featured pirinixic acids we were able to identify the most potent selective PPARγ agonistic pirinixic acid derivative (compound 13, (2-[(4-chloro-6-{[4-(naphthalen-2-yl)-1,3-thiazol-2-yl]amino}pyrimidin-2-yl)sulfanyl]octanoic acid)). Therefore, docking of 13 on PPARγ was performed to determine the potential binding mode.

Peroxisome proliferator-activated receptors (PPARs) are attractive targets for the treatment of the metabolic syndrome. Especially a combination of PPARα and PPARγ agonistic activity seems worthwhile to be pursued. Herein we present the design and synthesis of a series of pirinixic acid derivatives as potent PPARα particularly dual PPARα/γ agonists with 2-((4-chloro-6-((4-(phenylamino)phenyl)amino)pyrimidin-2-yl)thio)octanoicacid having the highest potential. Our investigations based on molecular docking and structure-activity relationship (SAR) studies elucidated structural determinants affecting the potency at PPARα. A diphenylamine-scaffold seems to play a key role. Careful in silico analysis revealed an essential role for a hydrogen bond between the diphenylamine and a water cluster. We confirmed this hypothesis using a mutated PPARα LBD in our transactivation assay to disrupt the water cluster and to validate the proposed interaction.

Peroxisome proliferator-activated receptor gamma (PPARgamma) is involved in glucose and lipid homeostasis. PPARgamma agonists are in clinical use for the treatment of type 2 diabetes. Lately, a new class of selective PPARgamma modulators (SPPARgammaMs) was developed, which are believed to show less side effects than full PPARgamma agonists. We have previously shown that alpha-substitution of pirinixic acid, a moderate agonist of PPARalpha and PPARgamma, leads to low micromolar active balanced dual agonists of PPARalpha and PPARgamma. Herein we present modifications of pirinixic acid leading to subtype-selective PPARgamma agonists and furthermore the development of a selective PPARgamma modulator guided by molecular docking studies.
