purpose of this work was to extend the group of oximes and study their hypotensive activity. The NO precursors were obtained on the basis of both well-known (Va/VIa, Vb/VIb, Ve/VIe, Vi/VIi) [14], (Vc/VIc, Vd/VId, VIIb] [13], and newly synthesized (VfiVlfVh/VIh) 2-arylmethylene-3-quinuclidone oximes and their hydrogenated analogs IXb and IXe. The compact r ind framework structure of quinuclidine (1-azabicyclo[2
将“内皮松弛因子”鉴定为血管内皮中由 L-精氨酸形成的内源性 NO [1],刺激了对新一代心血管药物的研究 [2-5]。目前,已经确定NO的生化合成通过不同途径进行。外源性有机硝酸盐(硝化甘油、亚硝基山梨醇和其他经典血管扩张剂)以及新的 NO 前体(如 N-硝基吡唑 [7] 和呋喃烷 [8])都会被还原 [6]。相反,L-精氨酸是生物体中主要的 NO 来源,被 NO 合酶 (NOS) 氧化为 NO 和 L-瓜氨酸 [2]。NOS 还能够从 [3-巯基乙基胍 [9, 10] 形成 NO。对我们已知的血管扩张剂 molsidomin 的研究表明,该药物通过与大气中的氧气反应生成 NO [3]。发现 1,2-二氮杂-1,2-二氧化物在热解和/或水解时形成 NO [I1]。穆勒等人。[12] 报道了在 pH 7.5 的溶液中使用 (+)-3-(E)-4ethyl2[(E)-hydroxyimino

The synthesis and antiplatelet activity of substituted pyrazolyl piperidinederivatives (3a–n) are described. These compounds were synthesized by an improved ring opening reaction of 2‐arylidene quinuclidinone using hydrazine hydrate under mild conditions. They were characterized and screened for their in vitro antiplatelet profile in human platelet aggregation using adenosine diphosphate as agonist
