Activation of the nuclear farnesoid X receptor (FXR) which acts as cellular bile acid sensor has been validated as therapeutic strategy to counter liver disorders such as non-alcoholic steatohepatitis by the clinical efficacy of obeticholic acid. FXR antagonism, in contrast, is less well studied and potent small molecule FXR antagonists are rare. Here we report the systematic optimization of a novel class of FXR antagonists towards low nanomolar potency. The most optimized compound antagonizes baseline and agonist induced FXR activity in a full length FXR reporter gene assay and represses intrinsic expression of FXR regulated genes in hepatoma cells. With this activity and a favorable toxicity-, stability- and selectivity-profile it appears suitable to further study FXR antagonism in vitro and in vivo.

Fatty acid amide hydrolase (FAAH) has a key role in the control of the cannabinoid signaling, through the hydrolysis of the endocannabinoids anandamide and in some tissues 2-arachidonoylglycerol. FAAH inhibition represents a promising strategy to activate the cannabinoid system, since it does not result in the psychotropic and peripheral side effects characterizing the agonists of the cannabinoid receptors. Here we present the discovery of a novel class of profen derivatives, the N-(heteroaryl)-2-(4-((2-(trifluoromethyl)pyridin-4-yl)amino)phenyl)propanamides, as FAAH inhibitors. Enzymatic assays showed potencies toward FAAH ranging from nanomolar to micromolar range, and the most compounds lack activity toward the two isoforms of cyclooxygenase. Extensive structure-activity studies and the definition of the binding mode for the lead compound of the series are also presented. Kinetic assays in rat and mouse FAAH on selected compounds of the series demonstrated that slight modifications of the chemical structure could influence the binding mode and give rise to competitive (TPA1) or non-competitive (TPA14) inhibition modes.

A synthetic method has been developed for the preparation of biologically important isoindolinones including indoprofen and DWP205190 drugs from 2-alkylbenzamide substrates by transition metal-free intramolecular selective oxidative coupling of C(sp3)-H and N-H bonds utilizing iodine, potassium carbonate and di-tert-butyl peroxide in acetonitrile at 110-140 °C.
