Synthesis and biological evaluation of nitric oxide (NO)-hydrogen sulfide (HS) releasing derivatives of (S)-3-n-butylphthalide as potential antiplatelet agents.

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.

Hydrogen sulfide (H(2)S) is considered as a new member of gasotransmitter family, following nitric oxide (NO) and carbon monoxide (CO). H2S exerts important biological effects in mammals, which has drawn more and more attention in recent years. It is proved that H(2)S has a role in the regulation of physiological and pathophysiological processes in the cardiovascular system and the nervous system.
