Two series of 1,3,4-oxadiazoline heterocycle derivatives were designed, synthesized and identified. Bioactivity assays showed that all synthesized compounds inhibited chitin synthesis in yeast, suggesting they might be a novel class of potential inhibitors against chitin biosynthesis. The structure-activity relationships (SAR) of these compounds are discussed. (C) 2008 Elsevier Ltd. All rights reserved.

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.
