Structure−Activity Relationship Studies Leading to the Identification of (2E)-3-[l-[(2,4-Dichlorophenyl)methyl]-5-fluoro-3-methyl-lH-indol-7-yl]-N-[(4,5-dichloro-2-thienyl)sulfonyl]-2-propenamide (DG-041), a Potent and Selective Prostanoid EP3 Receptor Antagonist, as a Novel Antiplatelet Agent That Does Not Prolong Bleeding
摘要:
The EP(3) receptor on the platelet mediates prostaglandin E(2) potentiation of thrombogenic coagonists including collagen and adenosine diphosphate (ADP). A pharmacophore driven approach led to the identification of diverse peri-substituted heterocycles as potent and selective EP(3) receptor antagonists. A simultaneous chemical optimization and druglike assessment of prioritized molecules converged oil a lead compound 50 (DG-041) that displayed favorable in vitro and functional activities as an inhibitor of human platelet aggregation. This agent is currently in human clinical trials for the treatment of atherothrombosis.

cathode oxygen reduction reaction. The features of this green protocol include the use of molecular oxygen as the sole oxidant, it being free of an electron transfermediator, and gram-scale preparation. Mechanistic studies suggested a radical process, and the two oxygen atoms in the isatins were both most likely from molecular oxygen. A detailed mechanism of the reaction utilizing density functional
