Octahydroindene was recognized like a novel scaffold for protease activated www.selleckchem.com/products/c646.html receptor 1 (PAR1) antagonists. Herein, the 2-position (C2) was explored for framework activity romantic relationship (SAR) scientific studies. Compounds 14, 19, and 23b showed IC50 values of Ferroptosis 1.three, 8.six, and 2.7 nM within a PAR1 radioligand binding assay, respectively, and their inhibitory activities on platelet activation had been comparable to that of vorapaxar inside a platelet rich plasma (PRP) aggregation assay. This series of compounds showed large potency and no sizeable cytotoxicity; nevertheless, the compounds had been metabolically unstable in each human and rat liver microsomes. Existing investigate efforts are centered on selleck chemical optimizing the compounds to improve metabolic stability and physicochemical properties along with potency.
