  超声介导的10秒钟合成查耳酮作为潜在的法呢基转移酶抑制剂。

  摘要：

  在使用超声探针将（杂）芳基酮和（杂）芳基醛进行克莱森-施密特缩合反应之后，可以轻松快速地合成各种查耳酮和衍生物。与经典的磁力搅拌实验进行了比较，并进行了优化研究，表明氢氧化锂是所研究缩合物的最佳碱性催化剂。还分离了反应的副产物（β-羟基酮，二酮和环己醇）。在体外评估所有化合物抑制人法呢基转移酶的能力，后者是一种与癌症和罕见疾病有关的蛋白质，在NCI-60癌细胞系中也有。分子对靶蛋白具有抑制活性，对不同细胞系具有抑制细胞的作用，对MCF7乳腺癌细胞具有特定的活性。

  In the present study, using chalcone as a lead compound, a series of its derivatives (compounds 1-30) were designed and synthesised. Their activity of anti-pathogenic fungi of plants has been evaluated. It is found that these compounds have good antifungal activity against Sclerotinia sclerotiorum, Helminthosprium maydis, Botrytis cinerea, Rhizoctonia solani and Gibberella zeae. Among them, the inhibition of growth for compound 30 against S. sclerotiorum showed 89.9%, with the median effective concentrations (EC50) of 15.4gmL(-1). The inhibition of growth for compounds 28, 29 and 30 at a concentration of 100gmL(-1) against H. maydis is 90.3%, 90.7% and 91.1%, with EC50 of 15.1, 18.3 and 18.1gmL(-1), respectively.

  Three natural products, 1,5‐diphenylpentan‐1‐one, 1,5‐diphenylpent‐2‐en‐1‐one, and 3‐hydroxy‐1,5‐diphenylpentan‐1‐one, with good insecticidal activities were extracted from Stellera chamaejasme L. Based on their shared diaryl ketone moiety as ‘pharmacophores’, a series of diaryl ketones were synthesized and tested for insecticidal activity, acetylcholinesterase inhibitory activity, and antifungal activity. All synthesized compounds showed poor insecticidal and acetylcholinesterase inhibitory activities. Compound III with a furyl ring showed strong activities against plant pathogenic fungi. The IC50 of compound (E)‐1‐(2,4‐dichlorophenyl)‐3‐(furan‐2‐yl)‐ ‐prop‐2‐en‐1‐one (III2) was 1.20 mg/L against Rhizoctonia solani, suggesting its strong potential as a novel antifungal drug.
