Abstract
The introduction of active groups of natural products into the framework of pesticide molecules is an effective approach for discovering active lead compounds, and thus has been widely used in the development of new agrochemicals. In this work, a novel series of 1,2,3,4-tetrahydroquinoline derivatives containing a pyrimidine ether scaffold were designed and synthesized by the active substructure splicing method. The new compounds showed good antifungal activities against several fungi. Especially, compound 4fh displayed excellent in vitro activity against Valsa mali and Sclerotinia sclerotiorum with EC50 values of 0.71 and 2.47 μg/mL, respectively. 4fh had slightly stronger inhibitory activity (68.08% at 50 μM) against chitin synthase (CHS) than that of polyoxin D (63.84% at 50 μM) and exhibited obvious curative and protective effects on S. sclerotiorum in vivo. Thus, 4fh can be considered as a new candidate fungicide as a chitin synthase inhibitor. An accurate and reliable three-dimensional quantitative structure-activity relationship (3D-QSAR) model presented a useful direction for the further excogitation of more highly active fungicides. Molecular docking revealed that the conventional hydrogen bond mainly affected the binding affinity of 4fh with chitin synthase. The present results will provide a guidance to discover potential CHS-based fungicides for plant disease control in agriculture.

Abstract
Elevated plasma levels of hyaluronic acid (HA) is a disease marker in liver pathology and other inflammatory disorders. Inhibition of HA synthesis with coumarin 4-methylumbelliferone (4MU) has a beneficial effect in animal models of fibrosis, inflammation, cancer and metabolic syndrome. 4MU is an active compound of approved choleretic drug hymecromone with low bioavailability and a broad spectrum of action. New, more specific and efficient inhibitors of hyaluronan synthases (HAS) are required. We have tested several newly synthesized coumarin compounds and commercial chitin synthesis inhibitors to inhibit HA production in cell culture assay. Coumarin derivative compound VII (10'-methyl-6'-phenyl-3'H-spiro[piperidine-4,2'-pyrano[3,2-g]chromene]-4',8'-dione) demonstrated inhibition of HA secretion by NIH3T3 cells with the half-maximal inhibitory concentration (IC50) = 1.69 ± 0.75 μΜ superior to 4MU (IC50 = 8.68 ± 1.6 μΜ). Inhibitors of chitin synthesis, etoxazole, buprofezin, triflumuron, reduced HA deposition with IC50 of 4.21 ± 3.82 μΜ, 1.24 ± 0.87 μΜ and 1.48 ± 1.44 μΜ, respectively. Etoxazole reduced HA production and prevented collagen fibre formation in the CCl4 liver fibrosis model in mice similar to 4MU. Bioinformatics analysis revealed homology between chitin synthases and HAS enzymes, particularly in the pore-forming domain, containing the proposed site for etoxazole binding.
