代谢
本达松的代谢在一系列毒代动力学研究中进行了探讨,这些研究是在口服(大鼠和家兔)或静脉注射(小鼠)后进行的。本达松的代谢非常差,母化合物是主要的排泄产物。只能检测到少量的6-羟基本达松和8-羟基本达松。在大鼠、家兔和小鼠中,没有发现结合产物。
The metabolism of bentazone was investigated in a number of toxicokinetic studies following oral (rat and rabbit) or intravenous administration (mouse) ... . Bentazone was only poorly metabolized, with the parent compound being the predominant excretion product. Only small amounts of 6-hydroxybentazone and 8-hydroxybentazone could be detected. In rats, rabbits and mice, no conjugated products were found.

代谢
6-羟基苯嗪酮和8-羟基苯嗪酮是苯嗪酮的主要植物代谢物。由于处理过的植物的作物可能被人类、农场动物或宠物消费,原则上可能会预期接触到这两种化合物。尽管这两种代谢物已在哺乳动物中证明形成,因此可以被视为包含在母体化合物的毒理学测试中,但仍进行了特定的毒理学研究。已经证明,通过口服给药途径,苯嗪酮的8-羟基和6-羟基代谢物的毒性相当,且均比母体化合物毒性低。此外,两种代谢物在Ames试验中均为阴性,表明它们没有诱导细菌点突变的能力。由于苯嗪酮环系统中羟基基团的转移不太可能显著改变毒性,因此决定对8-羟基苯嗪酮作为参考物质进行进一步调查。因此,在亚慢性喂养研究中、在几个诱变性研究中以及在胎儿发育研究中对8-羟基苯嗪酮进行了调查。这些调查发现,这些代谢物没有诱变或致畸潜力,并且比母体物质毒性更低。
6-Hydroxybentazone and 8-hydroxybentazone are major plant metabolites of bentazone. Because crops of treated plants can be consumed by humans, farm animals or pets, an exposure to both of these compounds might be expected in principle. Although both metabolites have been demonstrated to be formed in mammals and therefore can be regarded as included in toxicological testing of the parent compound, specific toxicological studies were performed. It has been shown that the 8-hydroxy and 6-hydroxy metabolites of bentazone are of comparable toxicity by the oral route of administration and are both less toxic than the parent compound. Additionally, both metabolites were negative in the Ames assay for the potential to induce point mutations in bacteria. As it is unlikely that a hydroxy group shift in the bentazone ring system dramatically changes the toxicity, it was decided to perform further investigations on 8-hydroxybentazone as a reference substance. Therefore, 8-hydroxybentazone was investigated in a subchronic feeding study, in several mutagenicity studies and in a prenatal developmental study. These investigations revealed that the metabolites have no mutagenic or teratogenic potential and are less toxic than the parent substance.

代谢
在大豆(Glycine max (Leguminatae) Merr.)和白扁豆(Phaseolus vulgaris Leguminatae)的研究中,观察到了四种未识别的共轭化合物。在叶面或根部吸收后,大豆迅速通过在6号和8号位置的羟基化代谢苯噻草。这些化合物被共轭化。对大豆田样品的分析显示,在早期生长阶段,苯噻草发生了羟基化。
In studies with soybeans [Glycine max (Leguminatae) Merr.] and navy beans (Phaseolus vulgaris Leguminatae), four unidentified conjugates were observed. After foliar or root absorption, bentazon was rapidly metabolized by soybeans with hydroxylation at the 6 and 8 position. These were conjugated. Analysis of soybean field samples showed hydroxylation of bentazon in early growth stages.

代谢
尽管抗性稻和易感夜香牛筋草对苯达松的吸收和转运没有明显差异,但其代谢却有很大差异。在稻中,吸收的苯达松在24小时内代谢了80%,并在7天内转化为85%的主要溶性代谢物。而在夜香牛筋草中,7天内只有25-50%的苯达松被代谢。其他抗性和易感植物物种也得到了类似的结果,表明能够代谢这种化合物是选择性的主要机制。稻中的主要代谢物通过气相色谱-质谱、核磁共振和红外光谱鉴定为6-(苯达松)-O-β-葡萄糖苷。其他研究表明,在大豆中6-和8-羟基苯达松以大约相等的量形成,而在小麦、稻、花生、千里光属植物和藜属植物中,6-羟基类似物占主导地位。
Although absorption and translocation of bentazon was not markedly different in resistant rice and susceptible C. serotinus, metabolism differed markedly. In rice, there was 80% metabolism of absorbed bentazon within 24 hr and 85% conversion to a major water soluble metabolite within 7 days. In C. serotinus, there was only 25-50% metabolism of bentazon in 7 days. Similar results were obtained with other resistant and susceptible plant species indicating that ability to metabolize this compound is the primary mechanism of selectivity. The primary metabolite in rice was identified by GC-MS, NMR and IR as 6-(bentazon)-O-beta-glucopyranoside. Other studies showed that the 6- and 8-hydroxybentazon were formed in about equal amounts in soybeans and that the 6-hydroxy analog predominates in wheat, rice, peanuts, Senecio sp., and Chenopodium sp.

  • 毒性总结
识别和使用:苯达松是一种白色结晶固体。它以前被用作除草剂。人类研究:苯达松对眼睛和粘膜有刺激性。一名50岁的男性因用苯达松溶液喷洒玉米后被送往医院,出现出汗、发热、恶心、呕吐清和出血性内容物、血性样大便。他根据症状接受了治疗,包括体外血液透析,但最终因多器官衰竭(急性呼吸衰竭、急性肝衰竭、凝血病、急性肾功能衰竭、代谢性酸中毒和胃肠道出血)在入院后11.35小时死亡。另一例中,故意服用130克苯达松导致呕吐、发热、出汗、管状肌肉僵直、窦性心动过速、嗜睡、白细胞增多、横纹肌溶解和肝肾损伤。动物研究:苯达松不是皮肤刺激物,但在兔眼中是中等刺激物。它在豚鼠中是皮肤致敏剂。在一项慢性毒性研究中,苯达松通过饮食给予大鼠(每组每种性别50只),剂量为0、5、17和76毫克/千克体重/天,持续2年。肿瘤发生率的统计分析没有显示各组之间的显著性差异。苯达松在兔或大鼠中不具有致畸性。在大鼠发育研究中,它在250毫克/千克体重/天时增加了着床后损失、骨骼变异(四肢指骨核、胸骨和颈椎的不完全或缺失骨化)并减少了胎儿存活到第21天的体重。饮食给予大鼠苯达松剂量平为0、300、1000和3500 ppm没有导致神经毒性的任何迹象。体外遗传毒性研究包括对沙门氏菌和李斯特菌的细菌反向突变试验、对大肠杆菌和酿酒酵母的DNA损伤和修复研究,以及CHO细胞中的染色体畸变和正向突变试验。体内研究包括小鼠和大鼠的染色体分析、小鼠的不定期DNA合成试验,以及小鼠和大鼠生殖细胞的突变试验。苯达松在所有这些研究中均给出了阴性结果。生态毒性研究:苯达松影响了斑马鱼胚胎和相关细菌群落。它对蜜蜂是无毒的。
IDENTIFICATION AND USE: Bentazone is a white, crystalline solid. It was formerly used as an herbicide. HUMAN STUDIES: Bentazone is irritating to eyes and mucous membranes. A 50-year-old male who had sprayed corn with a solution of bentazone was admitted to the hospital with sweating, fever, nausea, vomiting of aqueous and hemorrhagic content, and bloody, watery stools. He was treated according to the symptoms including extracorporeal hemodialysis, but eventually suffered from multiorgan failure (acute respiratory failure, acute liver failure, coagulopathy, acute renal failure, metabolic acidosis, and gastrointestinal bleeding) and died 11.35 hr after admittance. In another case, intentional poisoning with 130 g of bentazone resulted in vomiting, fever, sweating, pipe-like muscle rigidity, sinus tachycardia, drowsiness, leukocytosis, rhabdomyolysis and hepatorenal damage. ANIMAL STUDIES: Bentazone is not a skin irritant but was a moderate eye irritant in rabbits. It is a skin sensitizer in guinea-pigs. In a chronic toxicity study, bentazone was administered to rats (50 of each sex per group) via a diet at doses 0, 5, 17 and 76 mg/kg bw per day for 2 years. Statistical analysis of tumor incidence did not reveal any significance among the groups tested. Bentazone was not teratogenic in rabbits or rats. In rat developmental studies, it increased post-implantation loss, skeletal variations (incomplete or absent ossification in the phalangeal nuclei of the extremities, sternebrae and cervical vertebrae) and reduced body weights of fetuses surviving to day 21 at 250 mg/kg bw per day. Dietary administration of bentazone to rats at dose levels of 0, 300, 1000 and 3500 ppm did not result in any indication of neurotoxicity. In vitro genotoxicity studies included bacterial reverse mutation assays on Salmonella typhimurium and Escherichia coli, DNA damage and repair studies on E. coli and Saccharomyces cerevisiae, and chromosomal aberration and forward mutation assays in CHO cells. In vivo studies included chromosome analyses in mice and rats, unscheduled DNA synthesis tests in mice, and mutation assays in germ cells for mice and rats. Bentazone gave negative results in all of these studies. ECOTOXICITY STUDIES: Bentazone affected zebrafish embryos and associated bacterial communities. It was nontoxic to bees.

  • 致癌性证据
证据权重特征:根据美国环保局1986年的致癌风险评估指南,Bentazon将被归类为对人类非致癌性的证据,或者是一个E组化学物质。根据美国环保局提出的致癌风险评估指南,Bentazon被定性为不太可能通过任何暴露途径对人类致癌。此外,农药项目办公室健康影响部门的癌症同行评审委员会在评估已知的和提交的研究后得出结论,动物生物测定基本上没有显示出慢性喂养的致癌效应,在旧的分类系统中,这种化学物质被归类为具有致癌潜力的E组。Bentazon的代谢途径以及哺乳动物系统对其的处理被很好地理解,并且不产生任何显著的怀疑反应物。诱变性研究没有表明该化学物质有诱变性危险,与类似化学结构进行结构-活性比较,对于致癌潜力的显著影响是阴性的。人类致癌性数据:机构不知道有任何可用于审查的数据。动物致癌性数据:研究被认为足以评估动物中的致癌潜力。结果被认为不表明对测试动物有危险。...
WEIGHT OF EVIDENCE CHARACTERIZATION: Under EPA's 1986 Guidelines for Carcinogen Risk Assessment, Bentazon would be classified as evidence of non-carcinogenicity for humans, or a Group E chemical. Under EPA's proposed guidelines for carcinogen risk assessment, Bentazon would be characterized as not likely to be carcinogenic to humans by any route of exposure. Additionally, the Health Effects Division, Office of Pesticide Programs cancer peer review committee has concluded after evaluating the known and submitted studies that the animal bioassays were essentially negative for a carcinogenic effect from chronic feeding, and under the older classification system the chemical was classed as an E for carcinogenic potential. The metabolic pathways of Bentazon and the handling of it by the mammalian system are well understood and do not produce any significant suspect reactive species. The mutagenicity studies do not indicate a mutagenicity hazard from the chemical and structure-activity comparisons to similar chemical structures are negative for significant effects regarding carcinogenic potential. HUMAN CARCINOGENICITY DATA: The Agency is unaware of any data available for review. ANIMAL CARCINOGENICITY DATA: Studies were considered adequate for evaluation of the carcinogenic potential in animals. The results were considered to not be indicative of a hazard to test animals. ...

吸收、分配和排泄
毒物动力学研究对小鼠、大鼠和家兔进行的研究表明,苯达松通过口服途径被迅速且几乎完全吸收(> 99%),在低剂量(4 mg/kg 体重)时,大约15分钟内达到放射性血药浓度的峰值,在高剂量(200 mg/kg 体重)时,1小时内达到峰值。无论是以钠盐形式还是以自由酸形式给药,苯达松的吸收没有显著差异。没有证据表明它渗透到中枢神经系统或脊髓,并且从其他组织中迅速消除,没有生物累积的迹象。消除几乎完全通过尿液(约24小时内约91%);给药后5天,粪便中发现的不到2%,呼出空气中的不到0.02%。胆汁排泄的放射性物质极少。在不同物种(大鼠、家兔、小鼠)的调查中,吸收和消除没有显著差异。
Toxicokinetic studies performed on mice, rats and rabbits indicate that bentazone is rapidly and almost completely absorbed via the oral route (> 99%), and maximum blood concentrations of radioactivity are achieved in approximately 15 minutes at low doses (4 mg/kg bw) and by 1 hour at high doses (200 mg/kg bw). Administration of bentazone either as the sodium salt or as the free acid did not result in any significant differences in absorption. There was no evidence of penetration into the central nervous system or spinal cord, and elimination from other tissues was rapid, with no indication of bioaccumulation. Elimination was almost exclusively via the urine (approximately 91% within 24 hours); 5 days after dosing, less than 2% was found in feces and less than 0.02% in expired air. Biliary excretion of radioactivity was minimal. No significant differences were found in absorption and elimination among the different species investigated (rat, rabbit, mouse).

本研究的目的是评估[14C]bentazone钠盐(批号210-2201,放射性化学纯度97.3%)通过人类皮肤的渗透性。通过在Franz型扩散细胞上涂抹大约4933、49.3或8.22微克/平方厘米的活性成分,该成分被配制在BAS 351 32 H中,以分割厚度皮肤膜。这些剂量代表田间使用的浓缩配方或两种代表性的喷雾稀释液(1:100和1:600)。每个剂量的研究使用五个扩散细胞。结果表明,将bentazone配制成溶性(液体)浓缩型bentazone通过人类皮肤的体外渗透性可以适当地计算为吸收剂量的百分比。考虑到洗涤后与皮肤相关的放射性标记物质的量(剩余皮肤和胶带条3-6)作为可吸收的,并将这一点与受体中检测到的吸收量相结合,通过人类表皮的皮肤渗透程度大约为浓缩剂的0.06%,1:100喷雾强度稀释液的1.31%,1:600稀释液的1.23%。/Bentazone钠盐/
The dermal penetration of [14C]bentazone sodium salt (batch no. 210-2201, radiochemical purity 97.3%) through human skin was assessed by a single topical application of about 4933, 49.3 or 8.22 ug/sq cm of active ingredient formulated in BAS 351 32 H to split thickness skin membranes mounted on Franz-type diffusion cells. The doses represent the formulation concentrate or two representative spray dilutions (1:100 and 1:600) for field use, respectively. The study was performed using five diffusion cells per dose. ... It can be concluded that in vitro dermal penetration of bentazone formulated as an aqueous soluble (liquid) concentrate formulation of bentazone sodium through human skin is appropriately calculated as per cent absorbed dose. Considering the amount of radiolabeled substance associated with the skin (remaining skin and tape strips 3-6) after washing as absorbable and combining this with the absorbed amount detected in the receptor, the extent of dermal penetration through human epidermis is about 0.06% for the concentrate, 1.31% for the 1:100 spray strength dilution and 1.23% for the 1:600 dilution. /Bentazone sodium salt/

制备方法与用途

灭草松概述

灭草松又名苯达松排草丹等,是一种杂环类选择性触杀型苗后除草剂。在国内登记和实际应用的农作物包括稻(直播田和移栽田)、玉米、小麦、大麦、花生、高粱、大豆、蚕豆、菜豆、豌豆、洋葱、马铃薯、甘蔗、茶园、甘薯、苜蓿、草原牧场、暖季型草坪及部分中草药(如黄、板蓝根等)。

主要特性

灭草松具有以下特点:

  • 选择性高,主要针对杂草。
  • 使用后可迅速被植物吸收并传导至整个植株。
应用范围与使用方法

灭草松主要用于农田除草及草坪管理。它可通过叶片喷洒或土壤处理来去除各种杂草。具体施用量和时间需根据当地气候条件、土壤类型以及所要保护的作物种类进行调整。

生产工艺 一步法合成
  1. 异丙氨基磺酰氯制备

    • 异丙胺盐酸作用生成异丙胺盐酸盐,脱后收率可达90%~95%以上。
    • 然后在乙腈溶剂中与磺酰氯回流反应制得。原料配比为:1:3:6(摩尔比),沸腾回流反应需时不少于16小时,反应终温控制在60~70℃。
  2. 邻氨基苯甲酸甲酯的合成

  3. 灭草松合成

二步法合成

工业上可通过邻苯二甲酸酐为原料合成灭草松,具体步骤省略以简化说明。

安全与储存
  • 毒性分级:中毒。
  • 急性毒性:大鼠口服LD50值为1100毫克/公斤。
  • 可燃性危险特性:燃烧时产生有毒氮氧化物和氧化物气体。
  • 储运特性:库房需通风、低温干燥且与食品原料分开存放。
灭火剂

推荐使用干粉、泡沫或砂土进行灭火。
