Problems solved by technology

In view of this, piperine and its derivatives, in addition to the research on enzyme activity inhibition, anti-oxidation, anti-tumor, etc., are also used in protozoa Trypanosoma cruzi and Lehmania donovani, insect Culex larvae and Spodoptera frugiperda. There are certain studies on the poisonous activity of piperine

Abstract

The invention relates to piperine hydrazone, acylhydrazone or sulfonyl hydrazone derivative substances and application for preparing a botanical insecticide. The piperine hydrazone, acylhydrazone or sulfonyl hydrazone derivative substance takes the piperine hydrazone as raw materials, piperine aldehyde is obtained by means of hydrolysis, esterification, reduction and oxidation, and the piperine aldehyde is respectively reacted with replaced phenylhydrazine, the acylhydrazone and sulfonyl hydrazide. The structural formula is shown as follows. The experiment shows that the piperine hydrazone, or the acylhydrazone or the sulfonyl hydrazone derivative substances has the advantages of having good antifeedant and insecticidal activity, partly exceeds the parent piperine, wherein the insecticidal activity of some components is higher than the commercialized botanical pesticide toosendanin, and therefore the piperine hydrazone, or the acylhydrazone or the sulfonyl hydrazone derivative substances is expected to be used for preparing high-efficient, environment-friendly and low-toxic botanical insecticides.

Description

technical field [0001] The invention relates to a series of piperine hydrazone / acylhydrazone / sulfonyl hydrazone compounds with insecticidal activity, in particular to piperine hydrazone / acylhydrazone / sulfonyl hydrazone derivatives and their application for preparing plant-derived insecticides. Background technique [0002] Piperine is an amide derivative alkaloid in the piperaceae (Piperaceae) plant of the genus Piper. focus of research. [0003] In the existing literature, some studies have been done on the inhibition of enzyme activity, anti-oxidation, anti-tumor, and insecticide of piperine and its derivatives: for example: [0004] Document [Li-Hua Mu, Bo Wang, Hao-Yang Ren, et al.Synthesis and inhibitory effect of piperine derives on monoamine oxidase. Bioorganic & Medicinal Chemistry Letters.2012, 22, 3343-3348.] reported piperine and its synthetic amide, Ester derivatives have the effect of selectively inhibiting monoamine oxidase (MAO) A and B in vitro and [Surrind...
