title: Diacylhydrazine derivatives as novel potential chitin biosynthesis inhibitors: design, synthesis, and structure-activity relationship.
abstract: 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, (1)H NMR, (13)C 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.
