【摘要】 为了寻求新的含吡唑双酰肼类先导化合物,用4-取代-1-甲基-3-乙基-5-吡唑甲酰肼与取代苯甲(乙)酰氯进行缩合反应得到了10个1-吡唑甲酰基-2-芳基酰肼类化合物,其中9个是新化合物,其结构经IR,1H NMR,M S和元素分析确证。初步生物活性实验结果表明,在25μg/mL浓度下,3b和3 j对稻瘟病菌Pyricularia oryzae的抑制率分别为51.3%和56.1%;在1 000μg/mL下,3b对粘虫M ythimna separata的致死率达到100%。更多还原

【Abstract】 In order to find new lead compounds,9 novel and one known 1-pyrazol-5′-yl carbonyl-2-substituted benzoylhydrazides were prepared by a condensation reaction of 4-substituted-3-ethyl-1-methyl-5-pyrazole formhydrazide and substituted benzoyl chloride,and their structures were confirmed by()~1H NMR,MS,IR and elemental analysis.The preliminary bioassay showed that compounds 3b and 3j exhibited 51.3% and 56.1% inhibition rate against Pyricularia oryzae at 500 μg/mL,respectively.3b showed excellent fatality rate(100%) against Mythimna separate at 1 000 μg/mL.更多还原
