Enantiomers of 1′,6′-isoneplanocin, including derivatives of the enantiomers of 1′,6′-isoneplanocin, are disclosed along with novel synthetic methods. In particular, a substituted cyclopentane epoxide is synthesized into the enantiomers of 1′,6′-isoneplanocin. Enantiomers of carbocyclic nucleoside analogs of 3-deazaneplanocin to provide D- and L-like 1′,6′-iso-3-deazaneplanocin are also disclosed. The small molecule chemotherapeutic compounds beneficially provide DNA and RNA antiviral activity, demonstrating activity towards, for example, human cytomegalovirus, measles, Ebola, norovirus, dengue, vaccinia and HBV. Compounds exhibiting reduced S-adenosylhomocysteine hydrolase inhibitory effects are disclosed and provide improved toxicity profiles in comparison to neplanocin. The invention provides improved prophylactic and / or therapeutic antiviral efficacy.

The invention provides a sedge crop herbicidal suspoemulsion and its preparation method, application and application method, which relate to the field of agricultural technology. The herbicidal suspoemulsion for Cyperaceae crops provided by the present invention includes prometon, metolachlor-sperm and flurafen propargyl, the three have different mechanisms of action on weeds, and the three can interact with each other after being mixed according to a specific ratio. Cooperate, promote each other, and enhance the hindering effect on the growth of weeds. It not only has a high control effect on the annual weeds that have been unearthed, but also has a high control effect on some weeds that have been unearthed when the pesticide is applied, and it is safe for oily bean. high sex. The preparation method of the herbicidal suspoemulsion for Cyperaceae crops provided by the invention is simple and convenient, the prepared herbicidal suspoemulsion for Cyperaceae crops has good stability, and can be used for weed control in Cyperaceae economical and medicinal crop fields.

The invention belongs to the field of pesticides and specifically relates to a weeding compound containing halauxifen-methyl and triazine compound and an application thereof. The weeding compound comprises effective wedding dose of active ingredients, halauxifen-methyl and triazine compound, wherein the triazine compound is terbuthylazine and / or prometryn. The compound is capable of effectively preventing and eliminating weed, such as, starwort and descurainia sophia, in wheat field and is capable of achieving a synergic effect and widening the herbicide controlling spectrum.

The invention discloses a preparation method and application of a mass-selective monoclonal antibody capable of resisting 8 triazin type agricultural chemicals, and belongs to the technical field of biology. According to the preparation method disclosed by the invention, an appropriate activity arm is introduced into a 1,3,5- triazine ring, immune half-antigen and coating half-antigen are prepared, by an activity ester method, ovalbumin (OVA) and bovine serum albumin (BSA) are coupled to prepare immunogen and coating antigen, a Balb / c mouse is immunized by the immunogen, and a monoclonal antibody is prepared through a hybridoma technique; based on the antibody, the coating antigen is used as detection antigen, heterogenous indirect competitive enzyme-linked immunosorbent assay (ELISA) is established, and the mass-selective monoclonal antibody can be used for detecting 8 triazin type agricultural chemicals including prometryn, prometon, mesoran, secbumeton, atratone, desmetryn, simetrynand ametryn. The method is low in detection cost, high in sensitivity and simple and convenient in operation, and is suitable for on-site quick massive screening of the 8 triazin type agricultural chemicals.

The invention discloses a method for preparing the molecular engram solid phase micro-extraction coat, which comprises following steps: alkali cleaning, acid cleaning, activating and silanizing quartz fiber; assembling the template molecular and functional nomomer; adding crosslinking agnet and initiator, inserting silanized quartz molecular and thermally initiating the polymerization; extracting out the fiber to be aged; repeating aforementioned steps to reach needed thickness of coat; washing and removing the template molecular. Compared with commercial coat, the Prometryne molecular engram solid phase micro-extraction coat prepared by said method has better molecular recognition function on the triazine herbicide, while said coat is in porous structure without broken in long service. And its thickness can be adjusted via the plating times with better repeating ability. The extracting head can be used with the liquid chromatography, to separated and collect the triazine herbicide in the complex base as environment sample and food.
