Abstract To develop new phenazine carboxylic acid derivatives with better phloem mobility, five novel 7-amino acid substituted phenazine-1-carboxylic acids were synthesised by introducing amino acids into PCA at the 7-position. The phloem mobility experiments in Ricinus communis seedlings showed that retaining the carboxyl group of PCA and conjugating amino acids to its phenazine ring can also endow PCA
摘要 为了开发具有更好韧皮部迁移率的新型吩嗪羧酸衍生物,通过将氨基酸引入 PCA 的 7 位合成了五种新型 7-氨基酸取代的吩嗪-1-羧酸。蓖麻幼苗韧皮部迁移实验表明,保留PCA 的羧基并在其吩嗪环上缀合氨基酸也可以赋予PCA 韧皮部迁移能力。与我们之前的研究相比,我们发现在 PCA 吩嗪环上 7 位取代的氨基酸可以明显提高 PCA 的韧皮部迁移率,而不是与羧基共轭的氨基酸。特别是化合物7-L-异亮氨酸取代PCA( 7d )的韧皮部转运浓度比PCA-L-异亮氨酸偶联物高21倍(8d )。这些数据表明,在吩嗪环的不同结构位点引入氨基酸可以有效增强PCA的韧皮部迁移率,值得进一步研究。
