Abstracts

In this study, we prepared cordycepin-enriched (CE)-WIB801C, a n-butanol extract of Cordyceps militaris-hypha, and investigated the effect of CE-WIB801C on collagen-induced human platelet aggregation. CE-WIB801C dose-dependently inhibited collagen-induced platelet aggregation, and its $IC_{50}$ value was $175{\mu}g/ml$. CE-WIB801C increased cAMP level more than cGMP level, but inhibited collagen-elevated $[CA^{2+}]_i$ mobilization and thromboxane $A_2$ ($TXA_2$) production. cAMP-dependent protein kinase (A-kinase) inhibitor Rp-8-Br-cAMPS increased the CE-WIB801C-downregulated $[CA^{2+}]_i$ level in a dose dependent manner, and strongly inhibited CE-WIB801C-induced inositol 1, 4, 5-trisphosphate receptor ($IP_3R$) phosphorylation. These results suggest that the inhibition of $[CA^{2+}]_i$ mobilization by CE-WIB801C is resulted from the cAMP/A-kinase-dependent phosphorylation of $IP_3R$. CE-WIB801C suppressed $TXA_2$ production, but did not inhibit the activities of cyclooxygenase-1 (COX-1) and $TXA_2$ synthase (TXAS). These results suggest that the inhibition of $TXA_2$ production by WIB801C is not resulted from the direct inhibition of COX-1 and TXAS. In this study, we demonstrate that CE-WIB801C with cAMP-dependent $CA^{2+}$-antagonistic antiplatelet effects may have preventive or therapeutic potential for platelet aggregation-mediated diseases, such as thrombosis, myocardial infarction, atherosclerosis, and ischemic cerebrovascular disease.
