Description
技术领域
本发明涉及农药领域,具体来说涉及一种含苯并咪唑基团的苯基吡唑酰胺类衍生物,同时涉及该类衍生物的制备方法,还涉及该类衍生物在防治植物真菌病害方面的应用。
背景技术
农业病害,特别是真菌性病害,具有种类多、防治难的特点,一直是农业科学研究的重点和热点。有些种类病原真菌寄主范围广、危害时间长,不仅影响农作物的正常生长、产量和质量,还影响农产品的运输和存储,进而影响人们的生活和身体健康。合成杀菌剂在农作物病害的防治中一直发挥着重要作用,但是现有的一些杀菌剂作用靶标相对单一,加上农业生产者的不科学使用,使病原真菌的抗药性问题日益凸出,严重限制了杀菌剂的正常使用和农业的可持续发展。因此,研制高效、安全、经济、环保的新型杀菌候选物对防治农作物病害,保证农产品产量和质量,粮食安全具有重要意义。
苯并咪唑类化合物在杀菌剂的研究与应用领域中占有重要地位,如商品化杀菌剂多菌灵(Carbendazim)、噻菌灵(Thiabendazole)、麦穗宁(Fuberidazole)等都属于该类化合物。吡唑类化合物及其衍生物因其结构的可变性和高效广谱的生物活性,在农药领域也有着广泛的应用,主要表现在杀虫杀螨剂,杀菌剂及除草剂等方面,一直吸引着化学、药学和生物学领域研究者的兴趣。近年来,成为精细化工和农药领域研究的热点之一。苯基吡唑作为吡唑类化合物中的重要组成部分,在杀虫、杀菌领域发挥着重要作用。同时,在设计新型杀菌活性化合物时,人们经常将酰胺基团引入分子结构中,来合成、筛选高活性化合物。

其中,R1选自H、C1-6烷基、被1-3个卤素取代的甲基,R2选自H、卤素、NO2、C1-6烷基、C1-3烷氧基、被1-3个卤素取代的甲基,R3选自H、卤素、NO2、C1-6烷基、C1-3烷氧基、被1-3个卤素取代的甲基,Y(n)中,n=1-5取代,Y(n)选自下列1-5个基团:H、卤素、C1-6烷基、C1-3烷氧基、NO2、被1-3个卤素取代的甲基。
优选地,R1选自H、F、Cl、CH3、CHF2、CF3,R2选自H、卤素、NO2、C1-6烷基、C1-3烷氧基、被1-3个卤素取代的甲基,R3选自H、卤素、NO2、C1-6烷基、C1-3烷氧基、被1-3个卤素取代的甲基,Y(n)中,n=1-3取代,Y(n)选自下列1-3个基团:H、F、Cl、Br、CH3、C2H5、CH(CH3)2、OCH3、OC2H5、OCH(CH3)2、NO2、CF3、OCF3。
进一步优选地,R1选自CH3、CHF2、CF3,R2选自H、F、Cl、Br、CH3、CF3,R3选自H、F、Cl、Br、CH3、CF3,Y(n)选自H、2-Cl、3-Cl、4-Cl、4-F、4-Br、4-CH3、4-OCH3、4-NO2、2,4-Cl。
本发明还提供了式(I)化合物的制备方法:以式(II)2-(氨基苯基)-苯并咪唑化合物与式(III)取代苯基吡唑-4-甲酸反应,其反应方程式如下述通式(A)表示:
本发明的第三个方面涉及式(I)化合物作为杀菌剂的应用。
优选的,所得化合物作为杀菌剂或抑菌剂在防治或抑制植物病原真菌制剂的应用。
优选的,化合物作为杀菌剂或抑菌剂在制备抑制植物病原真菌制剂的应用。
进一步优选地,所述植物为农作物。
进一步优选地,所述化合物应用在制备抑制番茄灰霉病菌、水稻纹枯病菌、小麦赤霉病菌、番茄早疫病菌制剂。
进一步优选地,所述化合物应用在制备防治番茄灰霉病、水稻纹枯病、小麦赤霉病、番茄早疫病制剂。
有益效果:
1、本发明专利所述的式(I)的化合物为一种含苯并咪唑基团的苯基吡唑酰胺类衍生物,分子结构新颖,均为新化合物。化学结构特征鲜明,结构式中含有2-苯基苯并咪唑、苯基-5-(三氟甲基)-吡唑,苯环与吡唑环之间通过酰胺键相连接。
2、本发明所述的式(I)的化合物的制备方法简便,原料易得,反应条件易控。尤其是方法B使用缩合剂,使用缩合剂常温反应不需加热,产物经抽滤或者过滤即可得到。
3、本发明所述的式(I)的化合物表现出明显的抑制植物病原真菌的活性,具有防治农作物真菌病害的作用,能够作为农药杀菌剂应用。具体的说,化合物中含有苯并咪唑结构又含有(带三氟甲基的)吡唑结构,而且三氟甲基位于吡唑环的-5-位,与传统杀菌剂的三氟甲基位于3-位不同。苯并咪唑具有广谱杀菌活性,但长期使用导致真菌对其有抗药性,引入吡唑基团后,减缓抗性,同时使化合物具有新的双重作用机制---既具有苯并咪唑类化合物的作用机制,又具有吡唑酰胺类化合物的作用机制(SDHI抑制剂),杀菌谱广、真菌抗药性小。

用途实施例实施例4:本发明的式(I)化合物I1-I30的杀菌活性
本发明的式(I)的化合物I1-I30的杀菌活性测定以植物病原真菌番茄灰霉病菌(Botrytis cinerea)、水稻纹枯病菌(Rhizoctonia solani)、小麦赤霉病菌(Fusariumgraminearum)、番茄早疫病菌(Alternaria solani)为供试菌,采用菌丝生长速率法进行测定。
测定方法如下:
称取18mg的本发明式(I)的化合物I1-I30分别溶于0.8mL DMSO中,配置成母液,取200μL母液加入到45mL熔融无菌状态的马铃薯葡萄糖琼脂(PDA)培养基中摇匀,得到100mg/L的含药培养基,趁热均匀倒入三个无菌培养皿中,冷却凝固,依次得对应实验组I1-I30。以等剂量DMSO作为空白对照组,以相同条件下的恶霉灵为对照药剂组。
在培养基中央接入直径0.5cm的菌饼。每个药剂做3次平行实验。置于25±1℃恒温培养箱中黑暗培养一段时间后检查并记录药剂对真菌菌丝生长的抑制情况,并进行统计分析,所述时间由不同菌种菌丝生长速率决定。
菌丝生长抑制率(%)=(C-T)/(C-0.5)×100,C为空白对照菌落直径(cm),T为药剂处理菌落直径(cm)。
实验组I1-I30以及对照药剂组的杀菌活性测定结果见表1,对水稻纹枯病菌的抑制率,实验组I1-I30为27.43%-56.11%,对照药剂组为72.82±0.61。对番茄灰霉病菌的抑制率,实验组I1-I30为29.22%-90.41%,其中实验组I16、I21的抑制率分别达到81.74%和90.41%,对照药剂组为100.00±0.00。对小麦赤霉病菌的抑制率,实验组I1-I30为12.89%-52.63%,,对照药剂组为68.16±0.64。对番茄早疫病菌的抑制率,实验组I1-I30为25.71%-60.00%,其中实验组I23、I24、I27、I29的抑制率达到55.43%-60.00%,对照药剂组为55.43±1.53。
由表中结果可见,实验条件下,化合物I1-I30对4种植物病原真菌显示出不同程度的抑菌活性,部分高于对照药剂恶霉灵。
表1式(I)化合物I1-I30的杀菌活性(抑制率,%)
实施例5:化合物I1-I30对灰霉病菌的EC50值的测定
鉴于目标化合物对灰霉病菌具有较好的抑制活性,测试了化合物对灰霉病菌的EC50值,结果如表2所示。从表中可以看出,化合物对番茄灰霉病菌的EC50值较大,即目标化合物对灰霉病菌的活性偏低。其中化合物I11、I14、I18和I21对灰霉病菌的EC50值低于30μg/mL,分别为26.23、19.16、18.27和29.68μg/mL。
表2式(I)化合物I1-I30对灰霉病菌的EC50值
实施例6:化合物室内活体杀菌活性测试
在100μg/mL浓度下,化合物I14和I18对番茄灰霉病菌的防护效果如附图1、附图2和表3所示。化合物I14和I18对番茄灰霉病菌的保护防效分别为33.63%和41.11%,高于对照药剂恶霉灵的30.83%。
表3化合物I14和I18对灰霉的防效
