초록

Cordycepin (3'-deoxyadenosine) is an adenosine analog, isolated from Cordyceps militaris, and it has been used as an anticancer and anti-inflammation ingredient in traditional Chinese medicine. We investigated the effects of cordycepin (3'-deoxyadenosine) on human platelet aggregation, which was induced by thapsigargin, a tumor promoter, and determined the cytosolic free $Ca^{2+}$ levels ($[Ca^{2+}]_i$) (an aggregation-stimulating molecule) and cyclic-guanosine monophosphate (cGMP) (an aggregation-inhibiting molecule). Cordycepin inhibited thapsigargin-induced platelet aggregation in a dose-dependent manner, and it clearly reduced the levels of $[Ca^{2+}]_i$, which was increased by thapsigargin ($1\;{\mu}M$) or U46619 ($3\;{\mu}M$). Cordycepin also increased the thapsigargin-reduced cGMP levels. Accordingly, our data demonstrated that cordycepin may have a beneficial effect on platelet aggregation-mediated thrombotic diseases through the $[Ca^{2+}]_i$-regulating system such as cGMP.
