From table 5 and table 6, the 3-trifluoromethyl pyrazol compound that embodiment 1-30 is prepared 1h-NMR shows with number and its structure of the corresponding chemical shift of its structure, H identical, and corresponding skeleton absorption peak appears in IR.
The Antibacterial Activity of the prepared 3-methylpyrazole compound of embodiment 32 embodiment 1-30 to 7 kinds of common representative disease cause of diseases
(1) PDA substratum preparation: by the stripping and slicing of 200g peeling potatoes, add 1000mL distilled water, boil 10-20min.By filtered through gauze, add distilled water to 1000mL.Add 20g glucose and 17g agar, heating and melting, packing, high pressure steam sterilization 2h, standby.
(2) cultivation of pathogenic fungi: with a small amount of pathogenic bacteria mycelia of inoculating needle picking, on PDA substratum, be placed in 25 ℃ of constant incubators and cultivate 2-4 days, stand-by after mycelia grows.
(3) measuring method: adopt mycelial growth rate method (size of colony diameter in certain hour) to measure the bacteriostatic activity of compound.In centrifuge tube, accurately take 5mg for examination target compound, first by proper amount of acetone, dissolve, then add the aqueous solution that contains 1% polysorbas20 emulsifying agent of calculated amount, be diluted to the liquid of 1000mg/L.Get 1mL liquid and add in 9mL substratum and shake up, be mixed with the pastille substratum of 100mg/L, evenly pour culture dish into.Do not add and do blank containing the acetone that tries target compound altogether, contains same amount and the culture dish of polysorbas20 emulsifying agent substratum simultaneously.At well-grown, pollution-free with the punch tool (diameter 4mm) of sterilizing, the even colony edge of growing way is beaten and is got bacterium cake, under aseptic condition, access pastille substratum center (a bacterium cake of each culture dish inoculation), cover ware lid, ware covers down, and every processing repeats 3 times.Substratum is placed in to 25 ℃ of constant incubators and cultivates, after colony diameter expands to 4-5cm in contrast culture ware, by right-angled intersection method, measure and respectively process bacterium cake expansion diameter, average, relatively calculate relative bacteriostasis rate with blank.
(4) calculating of bacteriostasis rate:
Bacterium colony increases diameter (mm)=bacterium colony and measures diameter (mm)-bacterium cake diameter (mm)
Relative inhibition (%)=[contrast bacterium colony increases bacterium colony on diameter (mm)-pastille substratum and increases diameter (mm)]/contrast bacterium colony increases diameter (mm) * 100
According to the method described above, measure the fungistatic effect of the prepared 3-methylpyrazole compound of embodiment 1-30 to seven kinds of common representative disease cause of diseases, measurement result is (in table, data be the inhibition percentage that each compound is grown to pathogenic bacteria when 100mg/L) in Table 7.
Wherein, establish Azoxystrobin for contrast agricultural chemicals.
The 3-methylpyrazole compound fungicidal activity that table 7 embodiment 1-30 is prepared
