Many compounds containing a -CONH- group display photosynthesis inhibiting activity. Based on this structural feature, a group of anilides of 2-alkylthio-(1b-4f) or 2-chloro-6-alkylthio-4-pyridinecarboxylic acids (5a-6c) was synthesised. The prepared compounds were tested for their inhibition of the oxygen evolution rate (OER) in spinach chloroplasts. A quasi-parabolic dependence between photosynthesis-inhibiting activity and the lipophilicity of the compounds was determined for 1b-4f as well as for 5a-6c. The inhibitory activity of compounds 1b-4f was higher than that of 5a-6c for comparable lipophilicity values.
许多含有-CONH-基团的化合物显示出抑制光合作用活性。基于这一结构特征,合成了一组2-烷硫基-(1b-4f)或2-氯-6-烷硫基-4-吡啶羧酸的酰胺类化合物(5a-6c)。制备的化合物被测试了它们对菠菜叶绿体中氧进化速率(OER)的抑制作用。对于1b-4f以及5a-6c,确定了光合作用抑制活性与化合物亲脂性之间的准抛物线依赖关系。对于相似的亲脂性值,化合物1b-4f的抑制活性高于5a-6c。
