Description

Application of small molecule compound ZK-PI-9 in preparation of trehalase inhibitor
Technical Field
The invention relates to the technical field of insect control, in particular to application of a small molecular compound ZK-PI-9 in preparation of a trehalase inhibitor.
Background
China is a country with frequent biological disasters in agricultural production, thousands of tons of grains are lost due to insect pests on average every year, and the damage of the insect pests to crops is reflected not only in the aspect of reducing the yield of agricultural products, but also in the aspect of weakening the quality of the agricultural products. It is estimated that the potential food loss from world pests is around 45%. The use of pesticides to control pests is therefore unavoidable and important in agricultural production. However, long-term dependence on pesticides brings about serious 3R problems (drug resistance, residue and pest rampant), which not only does not achieve the purpose of pest control, but also causes a series of problems of environmental pollution, reduced biological diversity and the like. The method becomes an important means for green prevention and control of pests by regulating the growth and development of the pests, and is key to find a target gene capable of playing a regulating role and develop a proper biological pesticide.
Trehalose is a non-reducing disaccharide, the most important carbohydrate in insect haemolymph, and the energy released by hydrolysis is the main source of energy required for flight, development, molting and stress reactions. The trehalose can be used as an energy storage substance to participate in energy metabolism of organisms, and can also be used as a signal molecule to regulate glycolysis process and a structural substance to participate in the formation of insect body walls and regulate the growth and development of insects. Under various adverse conditions, the trehalose is used as a signal molecule energy source and a cell wall glycolipid component to protect organisms from environmental stresses such as high temperature, cold, dryness, hunger and the like, so that the vitality and the activity of insects are improved.
Trehalase is the only enzyme known in all organisms to break down trehalose and is also the first enzyme in the insect's in vivo chitin synthesis pathway. Inhibition of trehalase has been found to result in abnormal insect development, stunted growth, decreased flight ability and fertility, and increased mortality. And because trehalase is indispensable in insects and trehalase inhibition has no toxic effect on higher mammals, it has become one of important targets for pest control, and effective novel trehalase inhibitor products with practical pesticide significance are being developed.
A small molecule compound ZK-PI-9, the Chinese name of N- (4-chloro-2-methoxy-5-methylphenyl) -3-hydroxy-2-naphthamide, the molecular formula: c19H16ClNO3Relative molecular mass: 341.8 CAS registry number 5165-81-1, the structural formula is shown in formula I.
