NQ301是一种抗血栓剂; 可抑制胶原蛋白激发的兔血小板聚集，IC₅₀值为10 mg/mL。

NQ301 is an antithrombotic agent; inhibits collagen-challenged rabbit platelet aggregation with an IC 50 of 10 mg/mL.

Solid

IC50: 0.60±0.02 μM (collagen-challenged rabbit platelet aggregation), 0.58±0.04 μM (U46619-challenged rabbit platelet aggregation), 0.78±0.04 μM (arachidonic acid-challenged rabbit platelet aggregation)

NQ301 concentration-dependently inhibits collagen (10 mg/mL)-, U46619 (1 mg/mL)- and arachidonic acid (100 mg/mL)-challenged rabbit platelet aggregation, with IC50 values of 0.60±0.02, 0.58±0.04 and 0.78±0.04 μM, respectively. NQ301 potently suppresses thromboxane B2 formation by platelets that are exposed to arachidonic acid in a concentration-dependent manner, but had no effect on the production of prostaglandin D2, indicating an inhibitory effect on thromboxane A2 synthase. NQ301 has a potential to inhibit thromboxane A2 synthase activity with thromboxane A2/prostaglandin H2 receptor blockade, and modulate arachidonic acid liberation as well as 12-hydroxy-5,8,10,14-eicosatetraenoic acid formation in platelets. NQ301 inhibits platelet aggregation by suppression of the intracellular pathway, rather
