Protease-activated receptor-1 (PAR1), a G-protein-coupled receptor, plays a critical role in thrombin-mediated platelet aggregation. It is regarded as a promising antithrombosis target that is unlikely to result in bleeding. Here, we describe the synthesi

An original strategy for the synthesis of ketone 1, the key intermediate for preparing Etoricoxib, an important nonsteroidal anti-inflammatory drug, has been developed. Inexpensive 5-hydroxy-2-methylpyridine was converted to the corresponding acetyl derivative in four practical synthetic steps. The following palladium-catalyzed α-arylation of acetylpicoline with 4-bromo- or 4-chlorophenyl methyl sulfone was efficiently optimized in order to afford ketone 1 in remarkable yield.

Octahydroindene was identified as a novel scaffold for protease activated receptor 1 (PAR1) antagonists. Herein, the 2-position (C2) was explored for structure-activity relationship (SAR) studies. Compounds 14, 19, and 23b showed IC50 values of 1.3, 8.6, and 2.7 nM in a PAR1 radioligand binding assay, respectively, and their inhibitory activities on platelet activation were comparable to that of vorapaxar in a platelet rich plasma (PRP) aggregation assay. This series of compounds showed high potency and no significant cytotoxicity; however, the compounds were metabolically unstable in both human and rat liver microsomes. Current research efforts are focused on optimizing the compounds to improve metabolic stability and physicochemical properties as well as potency.
