Abstract
Insect chitinase, OfChi-h, from Ostrinia furnacalis, is considered as a promising target for the development of green pesticides. On the basis of the crystal structure of OfChi-h, we successfully obtained a triazolo-quinazolinone scaffold as the novel class of OfChi-h inhibitor via a structure-based virtual screening approach. Rational compound screening enabled us to acquire a potent OfChi-h inhibitor TQ19 with a Ki value of 0.33 μM. Furthermore, the in vivo biological activity of target compounds was assayed. The results showed that compounds TQ8 and TQ19 could dramatically inhibit the growth and development of Ostrinia nubilalis larvae, and most of the compounds showed higher insecticidal activity than hexaflumuron. This present work reveals that triazolo-quinazolinone derivatives can serve as novel candidates for insect growth regulators.

Abstract
Insect growth regulators (IGRs) are important insecticides that reduce the harm caused by insects to crops by controlling pest population growth. Chitinases are closely associated with insect growth and are among the most important glycoside hydrolases. Thus, Chitinase is an attractive target for the development of novel insecticides. In this study, we designed and synthesized a series of novel and highly potent insecticides targeting OfChtI and OfChi-h in insects. Enzymatic activity tests showed that most compounds exhibited a potent inhibitory activity against OfCh-h. Binding mode analysis revealed that the target compounds bound to the -1 active subsite of Chitinase through the key pharmacophore N-methylcarbamoylguanidino. Compounds 6e, 6g, 6j, and 6o significantly affected the growth and development of Plutella xylostella at 200 mg/L. Our study provides novel insights for the development of potent insecticide-targeted Chitinase combinations based on receptors and ligands.

Abstract
Chitinase OfChi-h, from the destructive agricultural pest Ostrinia furnacalis, is considered as a promising target for green pest control and management. In this study, structure-based virtual screening and rational molecular optimization led to the synthesis of a series of azo-aminopyrimidine derivatives as a novel class of OfChi-h inhibitors. Among them, the most potent compound 8f, with a benzyl on the amino group at the 4-position of pyrimidine, exhibited a Ki value of 64.7 nM against OfChi-h. In addition, molecular docking studies were carried out to investigate the basis for the potency of the aminopyrimidines against OfChi-h. Furthermore, the insecticidal activity of the target compounds against Plutella xylostella and Ostrinia nubilalis was assessed, and the potent OfChi-h inhibitors 8f and 8i showed higher insecticidal activity than the control pesticide hexaflumuron. The present work revealed that the azo-aminopyrimidine skeletons characterized by concise chemical structure and high efficiency could be further developed as potential pesticides for the control of lepidopteran pests.

Abstract
OfChi-h, a lepidopteran-exclusive glycoside hydrolase family 18 (GH18) chitinase from the agricultural insect pest Ostrinia furnacalis, is a promising molecular target candidate for pest control and management. Berberine (BER), a traditional Chinese medicine, binds to a wide variety of glycosyl hydrolases via an identical mechanism, showing potential as a pesticide lead compound. In this work, we found that BER was a moderate inhibitor of OfChi-h with a Ki of 16.1 μM. To improve its efficacy, a series of BER derivatives featuring an ester bond linked to an aromatic or heterocyclic aromatic ring at the 9-position were designed and evaluated as effective OfChi-h inhibitors. The most potent compound, compound 19e with a nicotinate group, exhibited a Ki of 0.093 μM. Molecular docking analysis suggested that the common binding mode of BER derivatives featured a network of π-π stacking and electrostatic interactions and that the group at the 9-position enhanced the van der Waals and hydrogen bonding interactions. Administration of the BER derivative 19c to 4th-instar O. furnacalis larvae in an artificial diet led to their impaired growth and metamorphosis. This work provides a new starting point for the modification of BER for use in pest control.
