代谢
A: NTN 33893, 纯度99.9%), B: 1-[(6--3-吡啶基)(14)C-甲基]-4,5-二氢-N-硝基-(1)H-咪唑-2-胺] (150.7 uCi/mg, 纯度>99%); 口服: 单次(1 mg/kg B, 20 mg/kg B), 多次(1 mg/kg A 每日一次 @ 14天,最后一次给药后24小时给予单次剂量的B); 静脉注射: 单次(1 mg/kg B); 每种性别/剂量5只大鼠; 给药后48小时内有超过90%的放射性物质被消除,所有剂量组中剩余在尸体中的不到1%; 在低剂量给药后,排泄模式和代谢物的性别差异不明显; 然而,在高剂量时,雌性的肾消除率略高于雄性; 雄性代谢试验化合物的能力更强,与雌性相比,母体化合物的量更低; 母体化合物的氧化断裂产生6-氯烟酸,然后与甘酸反应形成结合物(WAK 3583); 第二大代谢途径涉及在咪唑烷环的4-或5-位置进行羟基化并消除,产生代谢物NTN 35884; 这些代谢物通过尿液和粪便排出; 多次给药后没有报告生物累积的证据。
A: NTN 33893, 99.9% purity), B: 1-[(6-chloro-3pyridinyl)(14)C-methyl]-4,5-dihydro-N-nitro-(1)H-imidazol-2-amine] (150.7 uCi/mg, >99% purity); oral: single (1 mg/kg B, 20 mg/kg B), multiple (1 mg/kg A qd @ 14 days followed by 24 hrs after final dose by a single dose of B); IV: single (1 mg/kg B); 5 rats/sex/dose; >90% of administered radioactivity eliminated 48 hours after dosing with less than 1% remaining in the carcass in all dose groups; no sex differences in excretion pattern and metabolic profiles of the excreta were evident following low dose administration; however, at the high dose, females showed a slightly higher renal elimination rate than males; males showed a higher capacity to metabolize the test compound and the amount of parent compound was lower as compared to females; oxidation cleavage of the parent compound yields 6-chloronicotinic acid which then reacts with glycine to form a conjugate (WAK 3583); second major route of metabolism involves hydroxylation and elimination of water from the imidazolidine ring in the 4- or 5-position to produce the metabolite NTN 35884; these metabolites are excreted in urine and feces; no evidence of bioaccumulation following multiple dosing was reported.

代谢
甲烯-[(14)C]咪唑啉酮(86.4 - 123 uCi/mg, 纯度98.4 - 99%):单次给药[1 mg/kg(5只雄性),150 mg/kg(7只雄性)]和慢性处理未标记的咪唑啉酮1年,通过饲料给药,之后接受放射性标记的咪唑啉酮(80 mg/kg, 10只雄性);甲烯-[(14)C] WAK 3839(40 uCi/mg, 纯度99%):1 mg/kg(5只雄性);两种化合物在单次口服给药后均被迅速吸收;咪唑啉酮和WAK 3839的终末半衰期分别为35.7小时和46.9小时;在48小时内,给药剂量的75%的两种化合物主要通过尿液排出;粪便排出作用较小,因为分别有21%和16%的放射性物质通过这种方式排出;尿液中鉴定出了6-Cl-烟酸(WAK 3583)的甘酸结合物,两个单一羟基代谢物(WAK 4103)和未饱和代谢物(NTN 35884),这些代谢物占总放射性物质的82%;同样的代谢物也在粪便中被鉴定出;除了未改变的WAK 3839,还在接受WAK 3839处理的大鼠的尿液和粪便中鉴定出了另一种代谢物NTN 33823;WAK 3839和单次低剂量给药后识别的其他代谢物,在大鼠和小鼠长期接受饲料中咪唑啉酮处理后,在尿液中检测到;这一发现表明,WAK 3839是在长期暴露于咪唑啉酮期间形成的。
methylene-[(14)C] imidacloprid (86.4 - 123 uCi/mg, 98.4 - 99% purity): single [1 mg/kg (5 males), 150 mg/kg (7 males)] and chronic treatment with the unlabeled imidacloprid for 1 year in diet prior to receiving radiolabeled imidacloprid (80 mg/kg, 10 males); methylene-[(14)C] WAK 3839 (40 uCi/mg, 99% purity): 1 mg/kg 5 males); both compound absorbed rapidly after single oral dosing; terminal half-lives for imidacloprid and WAK 3839 are 35.7 and 46.9 hrs, respectively; 75% of the given dose of both compounds are eliminated primarily via urine within 48 hrs; fecal elimination plays a minor role, since 21% and 16% of the recovered radioactivity are excreted by this route, respectively; glycine conjugate of 6-Cl-nicotinic acid (WAK 3583), two monohydroxylated metabolites (WAK 4103) and the unsaturated metabolite (NTN 35884) were identified in the urine and accounted for 82% of the total radioactivity; same metabolites were also identified in feces; besides unchanged WAK 3839, one other metabolite NTN 33823 was identified in urine and feces obtained from rats treated with WAK 3839; WAK 3839 and other metabolites identified after a single low dose were detected in urine from rats and mice treated chronically with imidacloprid in their diet; this finding suggests that WAK 3839 is formed during chronic exposure to imidacloprid.

  • 毒性总结
识别和使用:吡虫啉(IM)形成无色晶体。它在美囀登记用于农药使用,但批准的农药用途可能会定期更改,因此必须咨询联邦、州和地方当局以获取当前批准的用途。IM用于控制农业和苗圃作物上的害虫、结构害虫和伴侣动物上的寄生虫。人类暴露和毒性:最常见的临床迹象包括:皮疹、呼吸困难、头痛、流泪、恶心、瘙痒、眩晕、唾液增多、呕吐、麻木和口干。报告了一例工人的眼睛溅入吡虫啉的情况。眼睛的临床体征是灼烧和角膜擦伤。两起致命病例中发现的IM血浓度分别为12.5和2.05微克/毫升。在HepG2细胞中由IM诱导的损伤是由于这种杀虫剂的裂解作用(76.6%的MN/微核试验/没有出现着丝粒信号)。动物研究:IM(纯度,94.2%)未刺激兔子的眼睛或皮肤,也未使豚鼠的皮肤敏感。IM单次口服给药对大鼠和小鼠具有中等毒性。在口服剂量大于或等于200毫克/千克体重的大鼠和大于或等于71毫克/千克体重的小鼠中,观察到行为和呼吸迹象、运动障碍、睑裂狭窄、短暂震颤和痉挛。临床体征在6天内逆转。在大鼠进行的慢性实验中,肝脏是主要靶器官,仅在高剂量雄性中观察到肝细胞肥大和散在细胞坏死。在研究结束时,肝脏病理变化轻微,并在恢复期间完全可逆。IM处理的雄性大鼠在睾丸和附睾中显示出组织病理学改变。在大鼠的发育研究中,观察到雄性胎儿百分比高和波状肋骨发生率增加。在兔子的发育研究中,基于观察到的流产、总胎吸收和由于晚期吸收增加导致的着床后损失增加,高剂量下繁殖力降低。然而,这个剂量平也导致体重和体重增加减少,并产生死亡率增加。早期发育暴露于IM对斑马鱼的神经行为功能具有早期生活和持久影响。在大鼠体内以170毫克/千克IM处理后,通过显微镜在骨髓细胞中确定了结构染色体畸变、异常细胞和有丝分裂指数。特别是雄性大鼠表现出对吡虫啉遗传毒性作用的易感性。生态毒性研究:IM对有益昆虫如蜜蜂Apis mellifera L的影响仍然存在争议。在农业生态系统中发现的平下,IM会降低对奖励的敏感性并损害年轻蜜蜂的联想学习。因此,一旦带有IM痕迹的花蜜流入蜂巢,它可能会损害室内职责,对蜂群表现产生负面影响。当实验室饲养的成年工蜂以亚致死剂量处理IM时,使用TUNEL技术进行DNA标记时检测到神经元凋亡。IM和5-OH-IM的行为效应使用嗅觉条件下的吻突伸展反应在一年中的两个时期进行了研究。冬季蜜蜂在慢性处理IM和5-OH-IM后存活,学习表现降低。夏季蜜蜂的IM最低观测效应浓度(12微克/千克)低于冬季蜜蜂(48微克/千克),这表明与冬季蜜蜂相比,夏季蜜蜂对IM的行为更加敏感。IM及其主要代谢物(5-羟基吡虫啉、4,5-二羟基吡虫啉、脱硝基吡虫啉6-氯烟酸、烯烃和尿素生物)在Apis mellifera中的口服急性和慢性毒性进行了研究。IM或其代谢物引起的急性中毒导致神经毒性症状的快速出现,如过度反应、过度活跃和震颤,并导致反应性和活动性降低。暴露于IM的地面黄蜂(Bombus terrestris audax)群体在殖民地生长和巢穴状况方面表现出比未处理群体更差。在绿头鸭繁殖研究中,在大于或等于61毫克/千克-饮食的浓度下观察到对蛋壳厚度的影响;在241 ppm时,雌性体重增加报告了52%的减少。在虹鳟鱼早期生活周期研究中,在大于或等于1.2毫克a.i./L的浓度下,观察到与处理相关的生长和存活下降。
IDENTIFICATION AND USE: Imidacloprid (IM) forms colorless crystals. It is registered for pesticide use in the USA but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. IM is used to control insect pests on agricultural and nursery crops, structural pests and parasites on companion animals. HUMAN EXPOSURE AND TOXICITY: The most common clinical signs included: rash, breathing difficulty, headache, tearing eyes, nausea, itching, dizziness, increased salivation, vomiting, numbness and dry mouth. One case was reported for a worker who had imidacloprid splashed into the eyes. The clinical signs were burning and corneal abrasion in the eye. IM blood concentrations found in two fatal cases were 12.5 and 2.05 ug/mL. The damage induced by imidacloprid in the HepG2 cells resulted from a clastogenic action of this insecticide (76.6% of the MN /micronucleus test/ did not present a centromeric signal). ANIMAL STUDIES: IM (purity, 94.2%) did not irritate the eyes or skin of rabbits and did not sensitize the skin of guinea-pigs. IM given orally as a single dose was moderately toxic to rats and mice. Behavioral and respiratory signs, disturbances of motility, narrowed palpebral fissures, transient trembling and spasms were seen in rats and mice treated orally at doses /greater than or equal/ to 200 mg/kg bw and /greater than or equal to/ 71 mg/kg bw, respectively. The clinical signs were reversed within 6 days. In chronic experiments conducted in rats, the liver was the principal target organ, with hypertrophy of hepatocytes and sporadic cell necrosis in high-dose males only. Liver pathology was mild at termination of the study and was fully reversible within the recovery period. IM-treated male rats showed histopathological alterations in testis and epididymis. In developmental studies in rats, there was a high percentage of male fetuses and an increased incidence of wavy ribs was observed. In a developmental rabbit study, fecundity was decreased at the high dose based on observed abortions, total litter resorptions, and increased post-implantation loss due to increased late resorptions. However, this dose level also resulted in decreases in body weight and body weight gain and produced an increase in mortality. Early developmental exposure to IM has both early-life and persisting effects on neurobehavioral function in zebrafish. Rats teated in vivo with 170 mg/kg IM, structural chromosome aberrations, abnormal cells and mitotic index were determined microscopically in bone marrow cells. Male rats in particular showed susceptibility to the genotoxic effects of imidacloprid. ECOTOXICITY STUDIES: IM effect on beneficial insects such as the honeybee Apis mellifera L is still controversial. IM administered at levels found in agroecosystems can reduce sensitivity to reward and impair associative learning in young honeybees. Therefore, once a nectar inflow with IM traces is distributed within the hive, it could impair in-door duties with negative consequences on colony performance. When laboratory-reared adult worker honey bees were treated with sublethal doses of IM, neuronal apoptosis was detected using the TUNEL technique for DNA labeling. Behavioral effects of IM and 5-OH-IM were studied using the olfactory conditioning of proboscis extension response at two periods of the year. Winter bees surviving chronic treatment with IM and 5-OH-IM had reduced learning performances. The lowest observed effect concentrations of IM was lower in summer bees (12 ug/kg) than in winter bees (48 ug/kg), which points to a greater sensitivity of honeybees behavior in summer bees, compared to winter bees. Oral acute and chronic toxicity of IM and its main metabolites (5-hydroxyimidacloprid, 4,5-dihydroxyimidacloprid, desnitroimidacloprid, 6-chloronicotinic acid, olefin, and urea derivative) were investigated in Apis mellifera. Acute intoxication by IM or its metabolites resulted in the rapid appearance of neurotoxicity symptoms, such as hyperresponsiveness, hyperactivity, and trembling and led to hyporesponsiveness and hypoactivity. Bumblebees (Bombus terrestris audax) colonies exposed to IM show deficits in colony growth and nest condition compared with untreated colonies. In mallard duck reproductive studies, effects on eggshell thickness were observed at concentrations of greater than or equal to 61 mg/kg-diet; a 52% decrease in female body weight gain was reported at 241 ppm. In the fish early-life cycle study with rainbow trout, treatment-related decreases in growth and survival were noted at concentrations of greater than or equal to 1.2 mg a.i./L.

标准生态毒理学风险评估是针对单个物质进行的,然而对农业区河流的监测表明,农药很少单独存在。实际上,像暴风雨径流和应用过程中的喷雾漂移这样的短暂但强烈的脉冲事件,会使淡环境受到高浓度农药混合物的影响。本研究调查了非目标生物暴露于短暂但强烈的硝基咪唑啉农药噻虫胺和噻虫啉以及拟除虫菊酯农药溴氰菊酯和高效氯氟氰菊酯混合物时可能产生的风险,并将其与单一物质暴露进行了比较。这四种农药都在地表中被检测到,其浓度高于基准值,并且已知这两类农药在单一物质暴露情况下对非目标生物产生不良影响。将非目标生物摇蚊的一龄幼虫暴露于这四种农药的混合物中,浓度为它们LC50(96小时)值的50%,持续1小时。然后将它们在没有污染的条件下饲养至成虫,并评估其存活率、发育时间和繁殖力。我们的结果显示,在这种情景下,非目标生物的生存和发育受到干扰的风险是不可忽视的,因为大多数农药暴露下发现了C. riparius的显著死亡率增加,以及拟除虫菊酯暴露后的发育延迟。虽然没有任何有害效应似乎因农药组合而放大,但有一些证据表明存在拮抗作用。任何农药处理对繁殖力都没有影响。
Standard ecotoxicological risk assessments are conducted on individual substances, however monitoring of streams in agricultural areas has shown that pesticides are rarely present alone. In fact, brief but intense pulse events such as storm water runoff and spray drift during application subject freshwater environments to complex mixtures of pesticides at high concentrations. This study investigates the potential risks to non-target aquatic organisms exposed to a brief but intense mixture of the neonicotinoid pesticides imidacloprid and thiacloprid and the pyrethroid pesticides deltamethrin and esfenvalerate, compared to single substance exposure. All four of these pesticides have been detected in surface waters at concentrations higher than benchmark values and both classes of pesticides are known to exert adverse effects on non-target aquatic organisms under single substance exposure scenarios. First instar midge larvae of the non-target aquatic organism, Chironomus riparius, were exposed to combinations of these four pesticides at 50% of their LC50 (96 hr) values in a 1 hr pulse. They were then reared to adulthood in uncontaminated conditions and assessed for survival, development time and fecundity. Our results show that the risk of disruption to survival and development of non-target aquatic organisms under this scenario is not negligible on account of the significant increases in mortality of C. riparius found in the majority of the pesticide exposures and the delays in development after pyrethroid exposure. While none of the deleterious effects appear to be amplified by combination of the pesticides, there is some evidence for antagonism. No effects on fecundity by any of the pesticide treatments were observed.

制备方法与用途

概述

吡虫啉是一种烟碱类超高效杀虫剂,具有广谱、高效、低毒、低残留的特点,害虫不易产生抗性,并对人、畜、植物和天敌安全。它不仅有触杀作用,还有胃毒和内吸等多重功效。

毒性

吡虫啉原药对雄性大鼠急性经口的LD₅₀为424 mg/kg,雌性大鼠为450~475 mg/kg;雄性、雌性大鼠急性经皮的LD₅₀大于5000 mg/kg;大鼠急性吸入LC₅₀大于0.5 mg/L。对兔眼睛和皮肤无刺激作用。对大鼠蓄积系数K大于5,未见长期或繁殖影响,并且运行试验未发现致癌或诱变作用。

鹌鹑急性经口的LD₅₀为31 mg/kg;蚤LC₅₀大于32 mg/L;蚯蚓在干土壤中的LC₅₀为10.7 mg/kg。

化学性质

纯品吡虫啉是一种白色结晶,熔点分别为143.8℃(A)和136.4℃(B),蒸气压为2×10⁻⁷ Pa (20℃)。在20℃时的溶解度分别为己烷小于0.1 g/L、异丙醇1~2 g/L、0.5 g/L。其在土壤中的稳定性较高,半衰期为150天。

用途

吡虫啉是一种化烟酰杀虫剂,具有内吸、胃毒和拒食等作用,主要针对刺吸式口器害虫如蚜虫、叶蝉、飞虱、蓟马等。此外,也可用于防治鞘翅目、双翅目和鳞翅目害虫。

吡虫啉已广泛应用于禾谷类作物、玉米、马铃薯、棉花、蔬菜、柑橘等作物中,还被开发为新的杀白蚊剂,在稻田里可以有效防治重要的跳虫和甲虫类。施用于育苗箱的颗粒剂剂量为0.2~0.3 kg/ha m²;防治甜菜潜叶甲虫和细胸针虫及各种蚜虫,施药量为117 g/ha m²;防治柑橘白蝇(西班牙)和介壳虫(希腊),建议使用0.01%~0.025%有效成分进行叶面喷洒。

国内对吡虫啉的应用研究十分活跃,相关文献包括《农药》1997年No. 7期的文章。

吡虫啉合成

吡虫啉的合成可采用以下步骤:

  1. 制备2--5-甲基吡啶(2):将0.25 mol的化合物(1)、0.37 mol三乙胺及250 mL CH₂Cl₂均匀混合,氮气保护下滴加邻苯二甲酰氯。滴毕后保温反应2小时,抽滤,CH₂Cl₂洗涤,冷却调pH值至6。馏出物分出油层,层萃取合并,干燥脱溶得无色至浅黄色油状液体。

  2. 制备2--5-甲基吡啶(3):将上步产物0.15 mol、苯8 mL混合,滴加含0.1 mol SO₂Cl₂的苯溶液。加热回流4小时后脱溶。

  3. 合成吡虫啉(4):将乙腈10 mL、N-硝基亚米唑烷-2-基胺0.15 mol、碳酸7.2 g混合,滴加溶有2--5-甲基吡啶0.1 mol的乙腈溶液。加热回流反应5小时后过滤,用乙腈洗滤渣,合并滤液脱溶得褐色固体。

另外一种合成方法是:以甲苯为溶剂,在室温下N-(2--5-吡啶甲基)亚乙基二胺与溴化氰作用生成环合产物。低温条件下加入浓硫酸中,并滴加发烟硝酸,于0℃反应2小时后得到吡虫啉
