Diacylhydrazine derivatives as novel potential chitin biosynthesis inhibitors: Design, synthesis, and structure–activity relationship
摘要:
A series of diacylhydrazine derivatives containing hydrophobic alkyl chains have been designed and synthesized. The target molecules have been identified on the basis of analytical spectral (IR, H-1 NMR, C-13 NMR, and HRMS) data. All synthesized compounds have been screened for their potential inhibition in vitro against chitin synthesis using yeast cell extracts. The preliminary assays indicate that some of the compounds display moderate to good inhibitory activity. Structure-activity relationship (SAR) is also discussed based on the experimental data, and the further analysis of the quantitative structure-activity relationship (QSAR) indicates that the electronic parameter is the main factor to affect inhibition activities.

chains were designed and synthesized by direct cyclization reaction of N′-alkylation substituted aroylhydrazines with chloroacetyl chloride. The preliminary assays showed that some of the compounds displayed moderate to good inhibitoryactivities toward monoamineoxidase (MAO) at the concentration of 10−5–10−3 M, and antitumor activities against human lung cancer A-549 and human prostate cancer PC-3 cell
通过N'-烷基化取代的芳酰肼与氯乙酰氯的直接环化反应,设计合成了一系列具有疏水性和长链性的含氮杂环4 H -1,3,4-恶二嗪-5(6 H)-ones衍生物。初步分析表明,某些化合物在10 -5 –10 -3 M的浓度下对单胺氧化酶(MAO)表现出中等至良好的抑制活性,并且对人肺癌A-549和人前列腺癌PC-具有抗肿瘤活性。 3个μM水平的细胞系,可能为抗癌药物提供新的支架。此外,化合物5i和5m 在几丁质生物合成中显示出显着的抑制活性,这可能代表了一类新型的几丁质合成抑制剂。
