①781094{2-[2(1,4-苯并二(口恶)烷)]-2-味唑啉盐酸盐}对肾上腺素以及由选择性(?)2-肾上腺能受体激动剂 UK-14304引起的人血小板聚集反应,起着强的竞争性抑制作用。②781094对可乐宁的原一聚集反应的抑制作用比对甲氧胺更强。(?)2/(?)1肾上腺素能受体择选性的比率为11.4。与肾上腺素和 UK-14304相反,当单独加入可乐宁、甲氧胺及苯肾上腺素时,并不能引起血小板聚集反应,但是增强了血小板对低浓度 ADP 的作用,即增强了 ① 781094 {2- [2 (1, 4-benzodiazepine)] - 2-Soxazolinium hydrochloride} on adrenergic and by the selective (?) 2-adrenergic receptor agonist UK -14304 caused by human platelet aggregation reaction, plays a strong competitive inhibition. ② 781094 of the initial aggregation of clonidine inhibition than methoxyamine stronger. (?) 2 / (?) 1 adrenergic receptor selectivity was 11.4. In contrast to epinephrine and UK-14304, clonidine, methoxyamine, and phenylephrine alone did not induce platelet aggregation but increased the effect of platelets on low concentrations of ADP
