代谢
使用(14)C放射性标记的氯磺胺甲基硫对F344大鼠进行了代谢研究,使用的剂量水平为5或1000毫克/千克。在5毫克/千克的剂量下,单次剂量或重复(15天)剂量的超过90%被吸收……尿液和粪便提取物的分析表明,母体氯磺胺甲基硫占排泄的放射性标记物质的大部分。唯一含量大于5%的代谢物被确认为氯磺胺甲基硫的4-OH苯基衍生物。其他次要代谢物包括嘧啶环的羟基化,尽管羟基化的位置未被确定,以及母体材料的N-乙酰半胱氨酸结合物。由于快速消除,氯磺胺甲基硫在重复给药时几乎没有累积的潜力。
Metabolism studies were conducted with (14)C-radiolabeled cloransulam-methyl in the F344 rat using dose levels of 5 or 1000 mg/kg. At 5 mg/kg, over 90% of either a single dose or repeated (15 days) doses was absorbed... Analyses of urine and fecal extracts indicated that parent cloransulam-methyl accounted for the majority of the excreted radiolabeled material. The only metabolite present at amounts greater than 5% was identified as the 4-OH phenyl derivative of cloransulam-methyl. Other minor metabolites included a hydroxylation of the pyrimidine ring, though the position of hydroxylation was not identified, and an N-acetyl cysteine conjugate of the parent material. Due to rapid elimination , cloransulam-methyl has little potential to accumulate upon repeated administration.

吸收、分配和排泄
一项对大鼠的新陈代谢研究显示,放射性标记的氯磺胺甲基硅烷主要通过尿液在雌性大鼠体内排出,在雄性大鼠体内则通过尿液和粪便排出。在给药后72小时内,在任何组织中发现的给药剂量不到0.1%。

吸收、分配和排泄
两只哺乳期的山羊连续五天每天口服给予(UL-苯胺-(14)C; AN)或(三唑嘧啶-7,9-(14)C; TP)-氯磺胺甲酯。每只动物接受相当于约10毫克/公斤的测试物质,约是奶牛实际最大饮食暴露量的2225倍。收集每只动物的上午和下午的牛奶、尿液和粪便样本。每只山羊在最后一次给药后23小时内被宰杀,并收集肝脏、肾脏、血液、脂肪、肌肉和胃肠道内容物样本,以及膀胱中的尿液。所有这些样本都分析了(14)C含量。氯磺胺甲酯(CM)被动物迅速排出,回收到的放射性活性的99.9%出现在尿液和粪便中。放射化学分析显示残留物非常低,最高的是在肾脏中的0.122和0.128毫克当量的CM/公斤(AN和TP标记的化合物)。从肾脏、肝脏和牛奶中提取并分离放射性残留物。分析显示肾脏中大约有0.066毫克/公斤的CM,但肝脏中<0.003毫克/公斤。只识别出一个代谢物,氯磺胺(在肝脏中,总放射性残留物的9.5%; 0.005毫克/公斤)。所有其他代谢物都存在于较低水平。磺酰苯胺桥断裂并不是反刍动物中氯磺胺甲酯显著降解途径。这些数据表明氯磺胺甲酯及其代谢物在反刍动物中的生物累积潜力非常低。对于暴露于预期水平的氯磺胺甲酯的反刍动物,父母和代谢物总量在肾脏和肝脏中预计不会超过50纳克/公斤。
Two lactating goats were given a daily oral dose of either (UL-aniline-(14)C; AN) or (triazolopyrimidine-7,9-(14)C; TP)-cloransulam-methyl for 5 consecutive days. Each animal received a dietary equivalent of approx 10 mg/kg of test material, approx 2225 times the realistic max dietary exposure for a dairy animal. Milk, urine, & feces samples were collected in the morning & afternoon for each animal. Each goat was sacrificed within 23 hr of receiving the last dose, & the liver, kidneys, samples of blood, fat, muscle, & GI tract contents, & urine from the bladder were collected. All of these samples were analyzed for (14)C content. Cloransulam-methyl (CM) was rapidly excreted by the animals, with 99.9% of the recovered radioactivity appearing in the urine & feces. Radiochemical analysis showed very low residues, with the highest being in the kidneys at 0.122 and 0.128 mg equiv of CM/kg (AN & TP labeled compounds, respectively). Radioactive residues were extracted & fractionated from kidney, liver, and milk. Analysis showed approx 0.066 mg/kg CM in the kidney but <0.003 mg/kg in the liver. Only one metabolite, cloransulam, was identified (in liver, 9.5% of total radioactive residue; 0.005 mg/kg). All other metabolites were present at lower levels. Sulfonanilide bridge cleavage was not a significant degradation route for cloransulam-methyl in ruminants. These data indicated a very low bioaccumulation potential for cloransulam-methyl & its metabolites in ruminants. For a ruminant exposed to anticipated levels of cloransulam-methyl in its diet, parent & metabolites, in total, would not be expected to exceed 50 ng/kg in the kidney & liver.

吸收、分配和排泄
代谢研究使用(14)C放射性标记的氯磺胺甲酯在F344大鼠中进行,剂量水平为5或1000 mg/kg。在5 mg/kg剂量下,无论是单次剂量还是重复(15天)剂量,超过90%被吸收。在1000 mg/kg剂量下,单次剂量的吸收率仅为28-30%。在这两种情况下,尿液排泄都很快,半衰期大约为6-9小时。与雄性(40-50%)相比,雌性大鼠通过尿液排出的5 mg/kg剂量比例更高(68-80%),这种性别依赖性的差异归因于雌性肾脏相对于雄性肾脏更有效地消除未改变的氯磺胺甲酯。
Metabolism studies were conducted with (14)C-radiolabeled cloransulam-methyl in the F344 rat using dose levels of 5 or 1000 mg/kg. At 5 mg/kg, over 90% of either a single dose or repeated (15 days doses was absorbed. At 1000 mg/kg, only 28-30% of a single dose was absorbed. Urinary elimination was rapid in both cases with half-lives of approximately 6-9 hr. A higher percentage of the 5 mg/kg dose was excreted in the urine by females (68-80%) than by males (40-50%) and these sex-dependent differences in disposition of the 5 mg/kg dose were attributed to more efficient elimination of unchanged cloarnsulam-methyl in the female versus male kidney.

作用机理

氯酯磺草胺属于乙酰乳酸合成酶(ALS)抑制剂。它是一种磺酰胺类除草剂,经杂草叶片、根吸收,累积在生长点,抑制乙酰乳酸合成酶(ALS),影响蛋白质的合成,使杂草停止生长而死亡。该药主要用于大豆田茎叶喷雾防除阔叶杂草。

磺酰胺类除草剂

氯酯磺草胺是美国陶氏益农公司最新研制的磺酰胺类除草剂,主要用于大豆田茎叶喷雾防除阔叶杂草。药剂经杂草叶片、根吸收累积在生长点,抑制乙酰乳酸合成酶(ALS),影响蛋白质的合成,使杂草停止生长而死亡。

田间药效试验表明,氯酯磺草胺对春大豆田阔叶杂草鸭跖草、红蓼、豚草有较好的防除效果,对苦菜、苣荬菜有较强的抑制作用。磺酰胺类除草剂与磺酰脲类除草剂类似,均是乙酰乳酸合成酶的抑制剂。它们以ALS为靶标,是涉及丙酮酸和硫胺素焦磷酸(TPP)的混合型抑制剂,对酶的结合部位进行竞争,而对基质或辅因子没有竞争作用。

磺酰胺类除草剂是由美国陶氏益农公司研制开发的一类新的乙酰乳酸合成酶抑制剂。其主要结构形式是三唑并嘧啶磺酰胺,现有6个品种,都是旱田除草剂,包括唑嘧磺草胺、甲氧磺草胺、氯酯磺草胺、双氯磺草胺、双氟磺草胺和五氟磺草胺。唑嘧磺草胺对大豆、玉米、小麦、大麦、豌豆、苜蓿、三叶草等安全,对后茬作物无不良影响;甲氧磺草胺主要用于防治小麦、大麦、黑麦田中大多数主要的阔叶杂草;氯酯磺草胺仅限于一年一茬的春大豆田施用。

注意事项
  1. 施用该药后的大豆叶片可能出现暂时一定程度的退绿药害症状,后期可恢复正常,不影响产量。在未使用过大豆新品种的情况下,在小试安全后,再大面积使用。
  2. 氯酯磺草胺仅限于一年一茬的春大豆田施用。对后茬作物的安全性试验:在推荐剂量下:
    • 小麦、大麦:施药后安全间隔期为3个月;
    • 玉米、高粱、花生的安全间隔期为10个月;
    • 甜菜、向日葵、烟草的安全间隔期为22个月以上。
