Design, synthesis and evaluation of novel 2-amino-3-(naphth-2-yl)propanoic acid derivatives as potent inhibitors of platelet aggregation

Add time:07/23/2019    Source:sciencedirect.com

Based upon LX2421, a previously identified antiplatelet aggregation agent, a series of novel 2-amino-3-(naphth-2-yl)propanoic acid derivatives were designed, synthesized and evaluated. Among them, compounds LX14 and LX25 were identified as promising antiplatelet aggregation agents. The in vitro biologic study demonstrated that LX14 can block platelet aggregation induced by four different inducers and displays comparable potency in inhibiting GPIIb/IIIa receptor in comparison with Tirofiban. In addition, LX14 has much lower risk of bleeding than Tirofiban and shows significant antithrombotic activity in vivo. Taking together, the results indicated that LX14 is a promising GPIIb/IIIa receptor antagonist against platelet aggregation worthy of further evaluation.
