Description

One class contains pyridine derivatives of 1,2,3-thiadiazoles and its production and use

Technical field

Technical scheme of the present invention relates to 1,2,3-thiadiazole compound, is specially the pyridine derivatives that contains 1,2,3-thiadiazoles.

Background technology

Isosorbide-5-Nitrae-dihydropyridine is a class significant group in synthetic, medicine, bioorganic chemistry.The derivative of Isosorbide-5-Nitrae-dihydropyridine is widely used in the treatment of cardiovascular disorder as a class agents of calcium ion channel modulators.Isosorbide-5-Nitrae-the dihydropyridine that replaces be a class can be in multiple receptors and ion cha nnels interactional particular bone shelf structure.Isosorbide-5-Nitrae-dihydropyridine compound has widely biological activity, such as anti-oxidant, anti-inflammatory, radioprotective, anticancer, hypoglycemic, immunomodulatory, neuroprotective, sterilization, antiviral etc. (Tetrahedron 65 (2009) 8344-8349).The Triphosphopyridine nucleotide, reduced of reduction-state once was called as triphosphopyridine nucleotide, it can with oxygen reduction be water as electron donor as a kind of Isosorbide-5-Nitrae-dihydrogen pyridine derivatives in respiratory chain, the tool (J.Org.Chem.2007 that plays a very important role, 72,8608-8610).

1,2,3-thiadiazole compound has widely biological activity (Bakulev, et al.Newyork:John Wiley ﹠amp equally; Sons, Inc, 2004), the research of relevant thiadiazoles mainly concentrates on 1,3,4-thiadiazoles derivative, 1,2, on 5-thiadiazoles derivative and 1,2, the 4-thiadiazoles derivative, and the research of 1,2,3-thiadiazoles derivative activity report is relatively less, commercial kind is few in medicine and the agricultural chemicals, and agriculture field is used cotton defoliant, the clever (N-phenyl-N '-1 of disleave, 2,3-thiadiazoles-5-urea, TDZ); Activating plants agent-Acibenzolar (phendioxin, 2,3-thiadiazoles-7-thiocarboxylic acid methyl esters, BTH); Rice field sterilant-tiadinil (3 '-chloro-4,4 '-dimethyl-1,2,3-thiadiazoles-5-formylaniline, TDL).The contriver in earlier stage designs synthetic and has found that the first thiophene lures the inducing anti-disease activity of amine, at present just in the industrialization development process.In order to seek 1 of high biological activity more, 2,3-thiadiazole new compound, for novel pesticide initiative research provides the candidate compound, the present invention is with 1,2, the 3-Thiadiazole is introduced in the Pyridine Molecules, and design has been synthesized a class and contained 1,2, the pyridine derivate of 3-thiadiazoles, and carried out the bioactive screening of system.

Summary of the invention

Technical problem to be solved by this invention is: provide novel and contain 1,2, the pyridine derivatives of 3-thiadiazoles and synthetic method thereof, biological activity and the measuring method thereof of this compounds regulation and control agricultural, gardening and health and forestry plant insect and pathogen are provided, the application of these compounds in agriculture field, gardening field, field of forestry and health field is provided.

The present invention solves this technical problem the technical scheme that adopts: what have that agriculture field, gardening field, forestry and health field insecticidal activity, fungicidal activity, anti-phytoviral activity, inducing plant produce anti-disease activity, insect growth regulator activity contains 1, the chemical structure of general formula of the pyridine derivatives of 2,3-thiadiazoles is seen formula I:
