2-(Methylthio)pyrido[2,3-d]pyrimidines having various alkylamino and anilino substituents at the 4-position were prepared and tested for their cytokinin agonistic and antagonistic activities by the tobacco callus bioassay. The alkyl series of compounds showed anticytokinin activity, whereas the anilino derivatives exhibited both cytokinin and anticytokinin activities depending on the structure and
制备了在4-位具有各种烷基氨基和苯胺基取代基的2-(甲硫基)吡啶并[2,3-d]嘧啶,并通过烟草愈伤组织生物测定法测试了其对细胞分裂素的激动和拮抗活性。烷基系列的化合物显示出抗细胞分裂素的活性,而苯胺基衍生物显示出细胞分裂素和抗细胞分裂素的活性,这取决于苯取代基的结构和位置。使用理化参数和回归分析对每种类别以及组合的化合物进行了定量的结构活性分析,表明活性质量(激动剂或拮抗物)以及活性程度均受到以下因素的显着影响:分子的空间特征。
