A novel series of 2-(phenoxyaryl)-3-urea derivatives were designed, synthesized, and biologically evaluated for their anti-thrombotic activity. Most of compounds exhibited good inhibition against P2Y₁ receptor. Among them, three compounds 11, 12, and 13 demonstrated good P2Y₁ receptor antagonistic potency in vitro (IC₅₀ = 0.62 μM, 0.82 μM, and 0.21 μM, respectively). In antiplatelet aggregation study, four compounds 2, 3, 9, and 13 showed good antiplatelet activity. The possible binding modes of compounds with P2Y₁ receptor were also explored by molecular docking simulation. The docking studies demonstrated that compound 13 interacted well with Phe119 through hydrophobic interaction and modestly improved the P2Y₁ receptor antagonistic activity, making it justifiable for further investigation.
