摘要: In the present study, a series of novel nitric oxide-hydrogen sulfide releasing derivatives of (S)-3-n-butylphthalide ((S)-NBP) were designed, synthesized, and evaluated as potential antiplatelet agents. 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 H2S, 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 an-tiplatelet agents for the treatment of thrombosis-related ischemic stroke.
