为了发现有高杀菌活性的先导化合物,通过活性亚结构拼接方法,将具有生物活性的肉桂醛与苯甲酰肼进行拼接,设计合成了一系列新型(3-取代苯基-2-丙烯-1-亚基)-酰腙类化合物. 该类化合物以取代的苯甲酸为原料,经3步反应制得,结构经1H NMR,IR及元素分析确证. 离体生测结果表明部分化合物对蘑菇酪氨酸酶及小麦赤霉病、黄瓜灰霉病和黄瓜炭疽病表现出一定的抑制活性,并对化合物进行了初步构效关系分析,其中化合物5r表现出与多氧霉素B相当的杀菌活性.

To find new lead compound with high fungicidal activity, a series of novel (3-substituted phenyl-2-propen-1- ylidene)-benzoylhydrazones were designed via the method of linking active sub-structures which were cinnamaldehyde and benzoylhydrazine. The target compounds were synthesized from substituted benzoic acid in three steps. Their structures were confirmed by 1H NMR, IR spectra and elemental analysis. The in vitro bioassay results indicated that some target compounds showed obvious inhibitory activities against mushroom tyrosinase compared with lead cinnamaldehyde. Besides, some target compounds exhibit certain fungicidal activity against Fusarium graminearum, Botrytis cinerea and Colletotrichum lagenarium. Compound 5r exhibited equivalent fungicidal activities to polyoxin B at a concentration of 100 μg/mL. The preliminary structure-activity relationship was also analyzed for further optimization.
