吸收、分配和排泄
在大鼠中进行的一项代谢研究中,使用放射性标记的吡虫啉,通过口服或静脉注射的方式将动物分组(每组五只/性别)以评估吸收和排泄。在给药后的前24小时内,所有口服给药组的尿液中含有52.0%-73.5%的放射性物质。静脉注射处理的大鼠在24小时内的尿液平也相似,分别为雄性和雌性给药剂量的63.6%和68.3%。在研究结束时(给药后7天),尿液(56.3-80.3%)、呼出气体(0.2-1.4%)、组织(0.3-3.8%)、粪便(15.4-38.9%)和笼子清洗(0.2-0.7%)中回收的放射性物质总计为91-100.7%的给药剂量,所有组别均如此。

Within the first 24 hr post-dosing, the urine from all orally-dosed groups contained from 52.0%-73.5% of the administered radioactivity. The iv treated rats also had comparable 24-hr urine levels which were 63.6% and 68.3% of the administered dose in males and females, respectively. At study termination (7 days post-dosing), the recovered radioactivity in urine (56.3-80.3%), expired air (0.2-1.4%), tissues (0.3-3.8%), feces (15.4-38.9%), and cage washes (0.2-0.7%) accounted for a total recovery of 91-100.7% of the administered dose in all groups.

吸收、分配和排泄
在雌性大鼠中进行的一项代谢研究,使用了标记在三嗪环吡啶基团上的哌甲酯,通过口服给药单一低剂量(0.5 mg/kg)或高剂量(100 mg/kg)。不论标记位置如何,低剂量和高剂量口服给药后达到最大血药浓度(tmax)的时间分别为1小时和8小时。峰值血药浓度取决于剂量但与标记位置无关。在所有时间点,不论剂量或标记位置如何,组织中残留平(ppm)在肾脏和肝脏中最高。除消化道外,所有组织中骨骼肌占给药剂量的百分比最高(两种标记),在低剂量1小时后占7-8%,在高剂量8小时后占19-21%。计算得出的三嗪残留物从所有组织中消失的半衰期(t1/2)为2.9-4.8小时(低剂量)和1.9-3.5小时(高剂量),而吡啶残留物消失的半衰期为31.7-110.3小时(低剂量)和2.5-13.9小时(高剂量)。高剂量的吸收较低,接近于给药剂量的82%。不论标记位置如何,低剂量的胆汁排泄高于高剂量。包括笼子清洗在内的总48小时排泄量,三嗪标记(低剂量/高剂量:103%/95%)高于吡啶标记(低剂量/高剂量:85%/81%)。因此,来自吡啶残留物的代谢物比来自三嗪基团的代谢物更持久。

吸收、分配和排泄
在大鼠皮肤吸收研究中,使用98.1-99.5%放射性标记的吡啶咪唑,对24只雄性大鼠进行了0.084、0.503或4.69毫克/只(0.0067、0.0402或0.375毫克/平方厘米)的剂量平的暴露。在血液收集后,每个剂量的四只大鼠在暴露0.5、1、2、4、10和24小时后被杀死,以评估皮肤吸收情况。在杀死大鼠时也收集了尿液和粪便。在暴露24小时后,皮肤吸收是最小的(低、中、高剂量组分别为0.05%、0.01%和<0.005%)。对于所有剂量组,大部分剂量(81.4-100.0%)未被吸收,并在皮肤清洗中被回收。对于所有剂量组,从测试部位吸附到皮肤的比例(0.18-8.84%)是剂量的下一个最大比例,而只有微量(<或=0.05%)的放射性物质在尿液和粪便中被排出。在每个剂量组内,清洗后留在/在皮肤上的放射性物质似乎并没有随着暴露时间的增加而增加;同样,吸收(通过排出的量加上体内保留的量来衡量)似乎也没有随时间增加。

After blood collection, four rats/dose were killed for assessment of dermal absorption after 0.5, 1, 2, 4, 10, and 24 hours of exposure. Urine and feces were also collected at the time of killing. After 24 hours of exposure, dermal absorption ... was minimal (0.05%, 0.01%, and <0.005% for the low, mid, and high dose groups, respectively). For all dose groups, the majority of the dose (81.4-100.0%) was not absorbed and was recovered in the skin wash. For all dose groups, adsorption to skin from the test site (0.18-8.84%) accounted for the next largest proportion of the dose and only trace amounts (< or =0.05%) of radioactivity were excreted in the urine and feces. Within each dose group, radioactivity remaining in/on the skin after washing did not seem to incr with the duration of exposure; likewise, absorption (measured as amount excreted plus amount retained in the body) did not seem to incr over time.

制备方法与用途

杀虫剂吡蚜酮

吡蚜酮(pymetrozine)是由瑞士原诺华公司于1988年开发的一种杀虫剂,属于吡啶类或三嗪酮类。它广泛应用于蔬菜、小麦、稻、棉花和果树等多种作物中,对多种刺吸口器害虫具有良好的防控效果,如甘蓝蚜、棉蚜、麦蚜、桃蚜、小绿斑叶蝉、褐飞虱、灰飞虱、白背飞虱、甘薯粉虱及温室粉虱等。

杀虫特点

吡蚜酮的主要特点是内吸性,能抑制昆虫取食,但无击倒活性,对刺吸式口器害虫高效。

用途

吡蚜酮稻、蔬菜、棉花、小麦和果树等多种作物的蚜虫、飞虱、叶蝉、粉虱等具有很高的防效。该药剂对同翅目害虫的选择性极佳,其选择性优于抗蚜威,还表现出良好的内吸性。

生物活性

Pymetrozine 是一种专化性的饲养抑制剂,能够防止如花椰菜马铃薯毛霉病毒传播的蚜虫种 Mysus persicae (Sulzer) 传播该病毒。

靶点

同翅类昆虫

作用机理

吡蚜酮属于吡啶类或三嗪酮类杀虫剂,是全新的非杀生性杀虫剂。最早由瑞士汽巴嘉基公司于1988年开发,对多种作物的刺吸式口器害虫表现出优异的防治效果。

电穿透图(EPG)研究表明,无论是点滴、饲喂或注射试验,蚜虫或飞虱一接触到吡蚜酮几乎立即产生口针阻塞效应,立刻停止取食,并最终饥饿致死。这种过程是不可逆转的,因此,吡蚜酮具有优异的阻断昆虫传毒功能。

使用禁忌

吡蚜酮对蜜蜂、鱼类等生物及家蚕有毒性,施药期间应避免影响周围蜂群。蜜源作物花期、蚕室和桑园附近禁用。养育稻田禁止使用,远离产养殖区施药,禁止在河塘等体中清洗施药器具。

体内研究

Pymetrozine 是一种快速作用且专化的害虫饲养抑制剂,在植物上进行现场试验时,电穿透图(EPG)技术表明,不同方式应用吡蚜酮对个体蚜虫的不同阶段的口针插入和取食活动有显著影响。高剂量不可逆地破坏了取食行为,而低剂量则导致短暂停止取食后恢复。

毒性

吡蚜酮毒性较低,对天敌的影响较小,仅作用于刺吸式口器害虫。该化合物对皮肤和眼睛均无刺激,且无致突变性。对于哺乳动物的毒性很低,对鸟类、鱼类及蜜蜂等也有很好的安全性。

应用

吡蚜酮具有触杀作用,并有内吸活性,在植物体内既能在木质部输导也能在韧皮部输导;因此可以用于叶面喷雾和土壤处理。由于其良好的输导特性,在茎叶喷雾后新长出的枝叶也可以得到有效保护。

    Pymetrozine (1) 通过用氧捕获其二价阴离子,然后用亚铁盐还原,以低到中等产率转化为半胺 2。Pymetrozines 18 和 19 未能进行这种类型的氧化。所有三种吡蚜酮均在 C5 处被电化学氧化为甲基半胺 20、21 和 22。20 到 2 的水解在酸或碱催化条件下以优异的产率完成,而甲基半缩醛 21 和 22 的水解最好在碱性条件下进行。pymetrozine 1、半胺类 2 和 3 的土壤代谢物以中等规模制备,产量极好。线性扫描伏安法数据和制备规模电化学条件是为前体吡蚜酮提供的。为所有新化合物提供完整的实验和光谱数据,并讨论了烷基酰胺的阴离子氧化与电化学氧化的相对优点。由于潜在的爆炸危险,对大规模阴离子氧化条件的描述提供了警告说明。
