Compound NOSH-NBP-5 displayed the strongest activity in inhibiting the arachidonic acid(AA)- and adenosine diphosphate(ADP)-induced platelet aggregation in vitro, with 3.8- and 7.0-fold more effectiveness than(S)-NBP, respectively. Furthermore, NOSH-NBP-5 could release moderate levels of NO and H2 S, which would be beneficial in improving cardiovascular and cerebral circulation. Moreover, NOSH-NBP-5 could release(S)-NBP when incubated with rat brain homogenate. In conclusion, these findings may provide new insights into the development of novel antiplatelet agents for the treatment of thrombosis-related ischemic stroke.展开更多
