38 title compounds have been synthesized. They bear a wide variety in substituents including alkyl‐, aryl‐, arylalkyl‐, and styryl groups. The antiplatelet activities elucidated in the Born‐test with collagen cover more than two orders of magnitude (IC50 = 0.3‐45 μmol/L). These effects depend on the presence of the N‐NO‐group. This is shown by comparison with the corresponding sydnone imines, sydnone
已合成38个标题化合物。它们带有多种取代基,包括烷基、芳基、芳烷基和
苯乙烯基。在用
胶原蛋白进行的 Born 试验中阐明的抗血小板活性覆盖超过两个数量级 (IC50 = 0.3-45 μmol/L)。这些影响取决于 N-NO 基团的存在。这通过与相应的sydnone
亚胺、sydnone
氰亚胺和sydnone的比较显示。最合适的取代基是分子任一位置的苯乙基、
苯乙烯基和己基。七种化合物,大部分是

生物,IC50值低于1μmol/L。这表明活性的差异与化合物与血小板膜结合的能力有关。
