4-{3-[（3，5-二氯-2-羟基苯亚甲基）氨基]丙基}-4，5-二氢-1H-吡唑-5-酮（BAPP）是一种新的植物免疫激活剂。BAPP增强了水稻对稻瘟病的抗病性和一个防御相关基因的表达，而不抑制生长。此外，BAPP还能增强双子叶植物番茄和拟南芥对细菌病原菌的抗病性，而不抑制植物生长，表明BAPP可能是一种有效的植物激活剂。利用拟南芥npr 2 -1和npr 1 -2突变体的分析表明，BAPP通过刺激水杨酸生物合成和SA受体蛋白NPR 1之间的SAR信号通路诱导系统获得抗性（SAR）。
A newly identified chemical, 4-{3-[(3,5-dichloro-2-hydroxybenzylidene)amino]propyl}-4,5-dihydro-1H-pyrazol-5-one (BAPP) was characterized as a plant immunity activator. BAPP enhanced disease resistance in rice against rice blast disease and expression of a defense-related gene without growth inhibition. Moreover, BAPP was able to enhance disease resistance in dicotyledonous tomato and Arabidopsis plants against bacterial pathogen without growth inhibition, suggesting that BAPP could be a candidate as an effective plant activator. Analysis using Arabidopsis sid2-1 and npr1-2 mutants suggested that BAPP induced systemic acquired resistance (SAR) by stimulating between salicylic acid biosynthesis and NPR1, the SA receptor protein, in the SAR signaling pathway.
