“…In view of the importance of Of Chi-h, several inhibitors with different chemical structures have been reported to date, such as chitoheptaose, TMG-(GlcNAc) 4 , , phlegmacin B 1 , dipyrido-pyrimidines, , azo-aminopyrimidines, berberines, rhodanines, methylcarbamoyl-guanidines, , thiazolylhydrazones, deoxyshikonin, polonimides, lynamicin B, and SN-38 (Figure ). However, many of the reported inhibitors (especially glycosyl-based inhibitors) have limitations in poor physicochemical properties and complicated synthesis processes. , Thus, the focus of the present study is to develop a type of novel and potent Of Chi-h inhibitor with a concise structure and suitable pesticide-like properties.…”
