Fifteen new indazole derivatives have been synthesized. In the Born test, compounds 4f and 4g were most active. They inhibited the blood platelet aggregation induced by collagen with an IC50 = 85 or 90 μM, respectively. After oral administration to rats (60 mg/kg) three of the compounds significantly inhibited the formation of thrombi in arterioles and venules. The strongest effect was observed with
已经合成了十五种新的吲唑衍生物。在 Born 试验中,化合物 4f 和 4g 的活性最强。它们分别以 IC50 = 85 或 90 μM 抑制胶原诱导的血小板聚集。对大鼠口服给药后 (60 mg/kg) 三种化合物显着抑制了小动脉和小静脉血栓的形成。使用 4j 观察到最强的效果,其显示对小动脉的抑制为 15%,对小静脉的抑制为 7%。进一步的实验表明,化合物 4j 不会通过激活可溶性鸟苷酸环化酶来介导这些作用,而是可能通过抑制磷酸二酯酶同种型 PDE 5 来介导这些作用。
