From
Table 3Giving birth to survey active testing result can find out, 50
μUnder the g/mL concentration, compound 2-methylsulfonyl-5-benzene base oxazole to gibberella saubinetii cause of disease bacterium (
G. zeae), the capsicum withered pathogenic bacteria (
F. oxysporum) and apple decay cause of disease bacterium (
C. mandshurica) bacteriostatic activity better, its inhibiting rate is respectively 71.0%, 58.4% and 64.3%, its activity slightly is superior to commodity compound and dislikes mould spirit (59.3%, 61.5%, 59.5%).Compound 2-methylsulfonyl-5-(2,4 dichloro benzene base)-oxazole to gibberella saubinetii cause of disease bacterium (
G. zeae), the capsicum withered pathogenic bacteria (
F. oxysporum) and apple decay cause of disease bacterium (
C. mandshurica) inhibiting rates of three kinds of fungies is respectively 65.4%, 63.7% and 57.0%, its activity is superior to or is equivalent to contrasting medicament and dislikes mould spirit.
The determination of activity of the indoor inhibition bacterial wilt of embodiment three: oxazole sulfone compounds
TP:
The bacterial wilt pathogenic bacteria is rule above the solid medium at NA (peptone 5g, yeast powder 1g, glucose 10g, agar 18g, zero(ppm) water 1L, PH 7.0-7.2), under 28 C, cultivate up to growing single bacterium colony.The single bacterium colony of bacterial wilt pathogenic bacteria is to liquid NA substratum on the picking NA solid medium, and is subsequent use to logarithmic phase at 30 C, 180 rpm constant temperature shaking table shaking culture.
Medicament and contrast medicament are configured to the toxic NB that concentration is 500,200 mg/L (beef peptone 3 g, peptone 5 g, yeast powder 1 g, glucose 10 g, zero(ppm) water 1 L, PH 7.0-7.2) liquid nutrient medium respectively, get 5 mL to test tube, add 40
μL contains the NA liquid nutrient medium of bacterial wilt germ, 30 C, 180 rpm constant temperature shaking table shaking culture 2 days, the bacterium liquid of each concentration is measured OD value (600 nm) on spectrophotometer.And measuring concentration in addition is the NB liquid nutrient medium OD value of 500,200 mg/L medicaments and contrast medicament, and the OD value that medicament itself causes is proofreaied and correct.The calculation formula of proofreading and correct OD value and preventive effect is following:
Proofread and correct OD value=contain bacterium culture medium OD value-aseptic culture medium OD value
Preventive effect %=(proofreading and correct the back control medium bacterium liquid OD value-toxic substratum OD of correction value)/control medium bacterium liquid OD value * 100 after proofreading and correct
Measure according to above method, the inhibition activity of part target compound is seen
