(Z)-2-methyl-3-(1H-perimidin-2-yl)acrylic acid (CPm-2) and 2-((1H-perimidin-2-yl)methyl)acrylic acid (IPm) have been studied. All perimidines bear aliphatic acidic substituents at 2-position andare distinguished by a carbon-carbon double bond in the substituents. The crystallographic X-ray diffraction analysis revealed that they exist in the solid state as zwitterions. Primary screening of 2-substituted 1H-perimidines
五种 2-取代 1 H - perimidines 的结构和电子性质:3-(1 H -perimidin-2-yl)propanoic acid ( SPm ), (Z)-3-(1 H -perimidin-2-yl)丙烯酸) ( MPm ), (Z)-3-(1 H -perimidin-2-yl)but-2-enoic acid ( CPm-1 ), (Z)-2-methyl-3-(1 H -perimidin-2 -yl)丙烯酸 ( CPm-2 ) 和 2-((1 H -perimidin-2-yl)methyl) 丙烯酸 ( IPm) 进行了研究。所有的嘧啶在 2 位带有脂肪族酸性取代基,并以取代基中的碳-碳双键为特征。晶体学 X 射线衍射分析表明它们以两性离子的形式以固态存在。还实现了针对不同癌细胞系的 2-取代 1 H -嘧啶的初步筛选。获得的结果在结构-性能关系方面进行了讨论,
