另一项关于雄性和雌性长埃文斯大鼠的新陈代谢研究进行了。这项研究包括七个大鼠组。进行了使用玉米油作为载体的口服给药研究和使用丙二醇作为载体的静脉给药研究。... 该研究被认为是了解大鼠如何代谢alachlor的决定性研究。使用六至九周大的雌性长埃文斯Crl:CD(LE)BR大鼠,对alachlor的口服给药进行了研究,分为五个剂量组。第1、2和3组每组各有33只大鼠。每个组单次口服给予放射性标记的alachlor(在苯环上均匀标记有14-C,并且在C-2碳上富集了13-C)的目标剂量为7(第1组)、70(第2组)或700(第3组)mg/kg。第4组由21只大鼠组成,连续15天每天给予700 mg/kg/day的放射性标记alachlor。第5组由6只大鼠组成,单次口服给予700 mg/kg的放射性标记alachlor,目的是在给药后2、4和6小时获取血浆样本。长埃文斯大鼠(每组性别各5只)用于研究在7(第6组)或70(第7组)mg/kg下静脉给药后alachlor的分布和代谢情况。... 在尿液中,alachlor的次酰胺羟甲基磺酰基代谢物(代谢物F5)在口服和静脉给药后是主要的尿液代谢物,占剂量的2.1-7.4%。重复口服给药导致出现几种额外的代谢物,但目前尚不清楚这些额外的代谢物是否仅限于重复口服给药的alachlor。在粪便中,单次口服alachlor后,叔酰胺巯基尿酸酸和二硫键似乎是主要的代谢物。增加剂量似乎增加了这两种代谢物在粪便中的百分比。
Another metabolism study was conducted on male and female Long Evans rats. This study consisted of seven groups of rats. Both oral dosing studies using corn oil as the vehicle and intravenous administration studies using propylene glycol as the vehicle were performed. ... The study is considered to be the definitive study for understanding how the rat metabolizes alachlor. Oral administration of alachlor was studied using female Long-Evans Crl:CD(LE)BR rats six to nine weeks of age in five dose groups. Groups 1, 2, and 3 each consisted of 33 rats. Each group received single oral doses of radiolabeled alachlor (uniformly labeled in the phenyl ring with 14-C, and enriched with 13-C at the C-2 carbon) at target doses of 7 (Group 1), 70 (Group 2), or 700 (Group 3) mg/kg. Group 4 consisted of 21 rats which received 15 consecutive daily doses of radiolabeled alachlor at 700 mg/kg/day. Group 5 consisted of 6 rats which received a single oral dose of radiolabeled alachlor at 700 mg/kg for the purpose of obtaining plasma samples at 2, 4, and 6 hours post-dosing. Long Evans rats (5/sex/dose) were used to study the disposition and metabolism of alachlor following intravenous administration at 7 (Group 6) or 70 (Group 7) mg/kg. ... In urine, the sec- amide hydroxymethyl sulfone metabolite (metabolite F5) of alachlor was the predominant urinary metabolite after oral and intravenous administration, ranging from 2.1-7.4% of the dose. Repeated oral dosing resulted in the appearance of several additional metabolites, but it is not known whether these additional metabolites are unique to repeated oral administration of alachlor. In feces, the tert-amide mercapturic acid and the disulfide appeared to be the major metabolites after single oral doses of alachlor. Increasing the dose appeared to increase the percentage of these 2 metabolites in feces.

在这项研究中,雄性和雌性CD-1小鼠(每种性别10只)口服单次剂量的放射性标记的alachlor(玉米油中雄性小鼠890 mg/kg,雌性小鼠819 mg/kg)。收集尿液和粪便,直至给药后7天,用于分析排泄的放射活性和识别代谢物。... 代表尿液0-48小时收集时间和粪便0-96小时收集时间的汇集尿液和粪便样本,用于分析雄性和雌性CD-1小鼠的alachlor代谢物。在粪便中,至少分离出10种代谢物:... / tert-酰胺巯基尿酸、二硫键结合物、sec-酰胺巯基尿酸、tert-酰胺硫代醋酸、tert-酰胺羟基磺酮、tert-酰胺二羟基磺酮、苄基葡萄糖苷酸和tert-酰胺半胱氨酸结合物 + NCH2O-葡萄糖苷酸。在小鼠尿液中鉴定出7种代谢物:tert-酰胺半胱氨酸结合物、NCH2O葡萄糖酸、半胱氨酸亚砜(建议)、sec-酰胺二羟基磺酮、sec-酰胺羟基亚砜、sec-酰胺羟基磺酮和对氨基硫酸盐。/虽然小鼠和大鼠对alachlor的代谢使用相同的代谢途径,但在代谢物轮廓的定量上,小鼠和大鼠之间存在差异。发现小鼠粪便中含有比大鼠粪便更多的巯基尿酸结合物和更少的二硫键结合物。在小鼠尿液中观察到的尿代谢物数量大于大鼠尿液。小鼠尿液被发现含有比大鼠更多的葡萄糖酸结合物和半胱氨酸结合物,但含有较少的酚类(羟基化)代谢物。
In this study, male and female CD-1 mice (10/sex) received a single oral dose of radiolabeled alachlor in corn oil (890 mg/kg for male mice, 819 mg/kg for female mice). Urine and feces were collected daily for up to 7 days post-dose for analysis of excreted radioactivity and for identification of metabolites. ... Pooled urine and fecal samples representing the 0-48 hour collection time for urine and the 0-96 hour collection time for feces, were analyzed for metabolites of alachlor in male and female CD-1 mice. In feces, at least 10 metabolites were isolated: ... /tert-amide mercapturic acid, disulfide conjugate, sec-amide mercapturic acid, tert-amide thioacetic acid, tert-amide hydroxy sulfone, tert-amide dihydroxysulfone, benzyl glucuronide and tert-amide cysteine conjugate +NCH20-glucuronide. Seven urinary metabolites were characterized in the mouse: tert-amide cysteine conjugate, NCH2O glucuronic acid, cysteine sulfoxide (proposed), sec-amide dihydroxysulfone, sec-amide hydroxy sulfoxide, sec-amide hydroxy sulfone and para-amino sulfate./ While metabolism of alachlor utilizes the same metabolic pathways in mice as in rats, there are quantitative differences between mice and rats in the metabolite profile present. Mouse feces were found to contain greater amounts of mercapturic acid conjugate and lesser amount of disulfide conjugate than in rat feces. The number of urinary metabolites observed in mouse urine was greater than in rat urine. Mouse urine was found to contain greater amounts of glucuronic acid conjugates and cysteine conjugates than the rat, but a lesser amount of phenolic (hydroxylated) metabolites.

从恒河猴的新陈代谢研究中,通过静脉注射后,确定了五种尿代谢物。其中一种代谢物(也在大鼠和小鼠尿液中发现,N-[2-乙基-6-(1-羟基乙基)-苯基]-N-(甲氧甲基)-2(甲磺酰基)乙酰胺),在大肠杆菌的Ames试验中呈阳性反应,无论是否经过活化。这种代谢物是一种HEEA代谢物,以前在猴子中未被发现。在上述两种新陈代谢研究中发现的代谢物中,只有两种尿代谢物在大鼠和猴子中都有(次要和第三级的巯基尿酸共轭物)。在猴子尿液中没有发现侧链羟基化和硫酸盐共轭代谢物,而这些在大鼠中是存在的。
From a metabolism study in Rhesus monkeys, five urinary metabolites were identified after intravenous injection. One of these metabolites, (also found in rat and mouse urine, N-[2-ethyl-6-(1-hydroxyethyl)-phenyl]-N-(methoxymethyl)-2(methylsulfonyl)acetamide), tested positive in the Ames test with Salmonella typhimurium, with and without activation. This metabolite was an HEEA metabolite not previously identified in the monkey. Of the metabolites found in the above two metabolism studies, only two urinary metabolites were common to both the rat and monkey (secondary and tertiary mercapturic acid conjugates). Side chain hydroxylation and sulfate conjugation metabolites were not found in monkey urine as they were in rats.

吸收、分配和排泄
对恒河猴进行了三项药代动力学研究:一项是静脉给药途径研究,一项是涂抹alachlor乳油浓缩物(EC),另一项是涂抹alachlor微囊制剂(Mcap)。在所有三项研究中,监测了血液中放射性水平7天,尿液和粪便9到14天。静脉研究的目的是确定alachlor分布和消除的药代动力学。每剂量/性别给两只猴子单次剂量为0.24或2.4 mg/kg/天。在最初的15分钟内,alachlor在血液(全血、血浆和红细胞)中迅速分布,并在最初24小时内主要通过尿液迅速消除。在10天的研究期间,低剂量的约93.3%和高剂量的约99.6%通过排泄物排出。这种消除的主要途径是通过尿液(低剂量为82.1%,高剂量为91.4%)。在EC和Mcap的皮肤研究中,未稀释和稀释(EC为1:29,Mcap为1:17)的水中测试了配方,每性别/配方或稀释/EC或Mcap给两只猴子。剂量(EC:32 Fg/cm2和300 Fg/cm2;Mcap 10.8 Fg/cm2和217 Fg/cm2)应用于40 cm2的皮肤区域,并在去除前保留在皮肤上12小时。对于EC,alachlor的吸收速度较慢,在24小时后在血液中达到峰值。在低剂量动物(32 Fg/cm2)中,通过排泄放射性标记物和组织中保留的标记物估计的总皮肤吸收量为6-7%的雄性和12-13%的雌性,未校正。然而,由于这个测试组回收放射性标记测试物质的恢复率较差,范围为21到77%,实际通过皮肤吸收的测试物质的量的计算变得复杂。提交的数据表明,在模拟条件下的体外实验中,多达40%的施用剂量可能从皮肤蒸发,并且应用错误可能导致施用剂量比名义值低多达20%。面对这些不确定性,根据回收的放射性标记物的量计算了排泄和吸收的值。使用这些校正因子,吸收率为10-24%(低剂量)的男性和16-20%(低剂量)的雌性。对于EC,高剂量动物(300 Fg/cm2)的放射性标记物回收情况较好,应用校正因子对结果影响不大。吸收率为4-9%的男性和10-11%的雌性。还可以通过使用皮肤给药后尿液中排出的校正百分比放射性标记物与静脉给药后尿液中排出的平均百分比放射性标记物的比率来估计皮肤吸收的百分比,这个比率为87%。使用这个比率,低剂量EC组的皮肤吸收估计为9.2-24.8%的男性和16-21.8%的雌性。对于高剂量EC组,皮肤吸收估计为4.7-8.9%的男性和10.7-11.4%的雌性。因此,通过任一种计算方法都得到了相似的皮肤吸收估计值。对于Mcap,低剂量(10.8 Fg/cm2)的总皮肤吸收率为3-23%的男性和6-7%的雌性。对于高剂量(217 Fg/cm2),总皮肤吸收率为2-4%的男性和3-4%的雌性。还使用EC组讨论中指定的比率估计了皮肤吸收的百分比。使用这个比率,低剂量Mcap组的皮肤吸收估计为3.2-23.4%的男性和6.7-7.1%的雌性。对于高剂量Mcap组,皮肤吸收估计为2-3.8%的男性和2.2-3.9%的雌性。再次,通过任一种计算方法都得到了相似的皮肤吸收估计值。
Three pharmacokinetic studies on Rhesus monkeys were performed: an intravenous route of administration study, dermal application of alachlor emulsifiable concentrate (EC), and a dermal application of alachlor micro-encapsulate formulation (Mcap). In all three studies, the levels of radioactivity were monitored in the blood for 7 days, and urine and feces for 9 to 14 days. The purpose of the intravenous study was to determine the pharmacokinetics of alachlor distribution and elimination. Two monkeys/sex/dose were given single doses of 0.24 or 2.4 mg/kg/day. Alachlor was rapidly distributed in the blood (whole, plasma, and red blood cells) within the first 15 minutes, and rapidly eliminated in urine primarily within the first 24 hours. Approximately 93.3% of the low dose and 99.6% of the high dose were eliminated in excreta during the 10-day study period. The majority of this elimination was via the urine (82.1% low dose, and 91.4%, high dose). In both the EC and the Mcap dermal studies, the formulations were tested undiluted and diluted (1:29 for EC and 1:17 for Mcap) with water, 2 monkeys/sex/formulation or dilution/EC or Mcap. The dosages (EC: 32 Fg/cm2 and 300 Fg/cm2; and Mcap 10.8 Fg/cm2 and 217 Fg/cm2) were applied to a 40 cm2 skin area and were left on the skin for 12 hours before removal. For the EC the rate of alachlor absorption was slow and reached a peak in the blood after 24 hours. The total dermal absorption in the low dose animals (32 Fg/cm2), estimated from excretion of radiolabel and retention of label in tissues, was 6-7% in males and 12-13% in females, uncorrected. However, calculation of the actual amount of test material absorbed through the skin was complicated by the fact that recovery of radiolabelled test material in this test group was poor, ranging from 21 to 77% of the nominal amount applied. Data were submitted demonstrating that up to 40% of the applied dose could apparently evaporate from skin (under conditions simulated in vitro) and that application error could result in application of up to 20% less than the nominal value. In the face of these uncertainties, values for excretion and absorption were calculated based upon the amount of radiolabel that was recovered. Using these correction factors, absorption was 10-24 % (low dose) in males and 16-20% (low dose) in females. For the EC, recovery of radiolabel was better in the high dose animals (300 Fg/cm2), and application of a correction factor had little effect. Absorption was 4-9% in males and 10-11% in females. It is also possible to estimate a percent dermal absorption by using a ratio of the corrected percent radiolabel excreted in urine after dermal application to the average percent radiolabel excreted in urine after intravenous administration, which is 87%. Using this ratio, the dermal absorption estimates for the low dose EC group were 9.2-24.8% for males and 16-21.8% for females. For the high dose EC group, the dermal absorption estimates were 4.7-8.9% for the males and 10.7-11.4% for the females. Thus, similar estimates of dermal absorption were obtained by either method of calculation. For the Mcap, the total dermal absorption for the low dose (10.8 Fg/cm2) ranged from 3-23% in males and 6-7% in females. For the high dose (217 Fg/cm2) the total dermal absorption ranged from 2-4% in males and 3-4% in females. Percent dermal absorptions were also estimated using the ratio specified in the discussion of the EC group. Using this ratio, the dermal absorption estimates for the low dose Mcap group were 3.2-23.4% for males and 6.7-7.1% for females. For the high dose Mcap group, the dermal absorption estimates were 2-3.8% in males, and 2.2-3.9% in females. Again, similar estimates of dermal absorption were obtained by either method of calculation.

另一项关于雄性和雌性长埃文斯大鼠的代谢研究。该研究包括七组大鼠。进行了使用玉米油作为载体的口服给药研究和使用丙二醇作为载体的静脉给药研究。 ... 该研究被认为是了解大鼠如何代谢alachlor的决定性研究。对6至9周大的雌性长埃文斯Crl:CD(LE)BR大鼠进行了alachlor的口服给药研究,分为五个剂量组。第1、2和3组每组有33只大鼠。每组单次口服放射性标记的alachlor(在苯环上均匀标记为14-C,并在C-2碳上富集为13-C)的目标剂量为7(第1组)、70(第2组)或700(第3组)mg/kg。第4组有21只大鼠,连续15天每天口服放射性标记的alachlor,剂量为700 mg/kg/天。第5组有6只大鼠,单次口服放射性标记的alachlor,剂量为700 mg/kg,目的是在给药后2、4和6小时获得血浆样本。长埃文斯大鼠(每组性别5只)用于研究静脉给药后alachlor的处置和代谢,剂量为7(第6组)或70(第7组)mg/kg。在口服研究中,7或70 mg/kg剂量水平下的吸收基本完全,700 mg/kg剂量水平下的吸收略有下降。重复口服给药700 mg/kg对吸收没有显著影响。在该研究中,任何剂量水平下的残留放射性均不超过给药剂量的5%。以ug/g为基础,非腺体胃中的残留放射性高于腺体胃,除了在700 mg/kg剂量水平下给药后4小时。降低剂量减少了非腺体胃中剂量的百分比,但腺体胃中的剂量没有减少。与其它组织相比,在700或70 mg/kg剂量水平下,鼻甲在给药后8小时显示出二次放射性峰值。单次口服剂量为7、70或700 mg/kg时,排泄的alachlor衍生的放射性在尿液和粪便中大约相等,其中30-47%通过尿液排泄,41-45%通过粪便排泄。静脉给药7或70 mg/kg的排泄情况相似。重复口服给药700 mg/kg导致粪便中放射性排泄略有增加...
Another metabolism study was conducted on male and female Long Evans rats. This study consisted of seven groups of rats. Both oral dosing studies using corn oil as the vehicle and intravenous administration studies using propylene glycol as the vehicle were performed. ... The study is considered to be the definitive study for understanding how the rat metabolizes alachlor. Oral administration of alachlor was studied using female Long-Evans Crl:CD(LE)BR rats six to nine weeks of age in five dose groups. Groups 1, 2, and 3 each consisted of 33 rats. Each group received single oral doses of radiolabeled alachlor (uniformly labeled in the phenyl ring with 14-C, and enriched with 13-C at the C-2 carbon) at target doses of 7 (Group 1), 70 (Group 2), or 700 (Group 3) mg/kg. Group 4 consisted of 21 rats which received 15 consecutive daily doses of radiolabeled alachlor at 700 mg/kg/day. Group 5 consisted of 6 rats which received a single oral dose of radiolabeled alachlor at 700 mg/kg for the purpose of obtaining plasma samples at 2, 4, and 6 hours post-dosing. Long Evans rats (5/sex/dose) were used to study the disposition and metabolism of alachlor following intravenous administration at 7 (Group 6) or 70 (Group 7) mg/kg. In the oral studies, absorption at the 7 or 70 mg/kg dose levels was essentially complete, with a slight decrease in absorption at the 700 mg/kg dose level. Repeated oral dosing at 700 mg/kg had no significant effect on absorption. Residual radioactivity did not exceed 5% of the administered dose at any of the dose levels in this study. On a ug/g basis, the residual radioactivity in the non-glandular stomach was higher than in the glandular stomach except at 4 hours post-dose at the 700 mg/kg dose level. Decreasing the dose decreased the percentage of the dose in the non-glandular stomach but not in the glandular stomach. Nasal turbinates showed a secondary peak of radioactivity at 8 hours post-dose at the 700 or 70 mg/kg dose levels in contrast to other tissues. Excretion of alachlor derived radioactivity was approximately equivalent between urine and feces, with between 30-47% excreted in urine and 41-45% excreted in feces at single oral doses of 7, 70, or 700 mg/kg. Intravenous dosing at 7 or 70 mg/kg resulted in a similar excretion profile. Repeated oral dosing at 700 mg/kg resulted in a slight increase in fecal excretion of radioactivity...

吸收、分配和排泄
在这个研究中,10只雄性和10只雌性的CD-1小鼠单次口服了用玉米油配制的放射性标记的alachlor(雄性小鼠890 mg/kg,雌性小鼠819 mg/kg)。在给药后的7天内,每天收集尿液和粪便,以分析排泄的放射活性和识别代谢物。在尿液中,分别有18.4+/-3.9%和23.6+/-4.1%的剂量在雄性和雌性小鼠中被排泄。在粪便中,分别有66.5+/-6.9%和53.6+/-3.6%的剂量在雄性和雌性小鼠中被排泄。雄性小鼠的总放射活性回收率为85.5+/-3.7%,雌性小鼠为79.4+/2.7%。(回收率较低可能是由于小鼠被成对安置在比通常用于小鼠的单元更大的笼子中的原因。)在给药后七天的血液分析显示,雄性小鼠中有0.095+/-0.016%的剂量,雌性小鼠中有0.075+/-0.017%的剂量。...这项研究的数据显示,与大鼠相比,粪便是在CD-1小鼠中排泄alachlor派生物放射活性的主要途径。高百分比的粪便排泄可能是由于小鼠对测试化学物质吸收不良或在小鼠中胆汁排泄广泛的结果。
In this study, male and female CD-1 mice (10/sex) received a single oral dose of radiolabeled alachlor in corn oil (890 mg/kg for male mice, 819 mg/kg for female mice). Urine and feces were collected daily for up to 7 days post-dose for analysis of excreted radioactivity and for identification of metabolites. In urine, 18.4+/-3.9% and 23.6+/-4.1% of the dose was excreted in male and female mice, respectively. In feces, 66.5+/-6.9% and 53.6+/-3.6% of the dose was excreted in male and female mice, respectively. Total recovery of radioactivity was 85.5+/-3.7% for male mice, and 79.4+/2.7% for female mice. (The low recoveries may be due to the fact that the mice were housed in pairs in units larger than those normally used for a mouse.) Analysis of blood at seven days post-dose showed 0.095+/-0.016% of the dose in males, and 0.075+/-0.017% of the dose in females. ... The data in this study show that in contrast to the rat, feces is the major route of excretion for alachlor derived radioactivity in CD-1 mice. The high percentage of fecal excretion could be the result of poor absorption of test chemical or extensive biliary excretion in the mouse.

...恒河猴体内经皮吸收alachlor的百分比为17.3 ± 3.3、15.3 ± 3.9 和 21.4 ± 14.2%,分别对应于24小时暴露于1:20、1:40和1:80稀释的Lasso制剂。在体内,没有证据支持水稀释会增加alachlor的皮肤吸收,这与之前体外吸收的报道相符。24小时内平均吸收18%的施用剂量(0.75%/h)与使用人类皮肤和人类血浆作为受体液的体外最大吸收率0.8%/h相似。体内剂量可追溯性为80.6-95.2%。将Lasso稀释1:20的水中的(14-14C)alachlor涂抹在恒河猴上,浓度为23微克/10微升/cm2。0小时时用肥皂和水(50%象牙液体与水1:1 v/v)清洗可去除73 ± 15.8%(n = 4)的施用剂量;经过两次额外清洗,总去除量增加到82.3 ± 14.8%。1小时后清洗可去除87.5 ± 12.4%,经过三次连续清洗。3小时后清洗能力降低,24小时后仅能通过三次连续清洗去除51.9 ± 12.2%。仅使用水时,0小时时第一次清洗可去除36.6 ± 12.3%的alachlor,总共去除量在两次额外清洗后增加到56.0 ± 14.0%。24小时后,三次连续清洗的总去除量减少到28.7 ± 12.2%。将Lasso作为田间使用率(11微克/cm2)和不稀释(217和300微克/cm2)比例的alachlor留在恒河猴皮肤上12小时,然后用肥皂和水(10%象牙液体与水v/v)清洗。连续清洗(连续6-8次)可回收80-90%的皮肤应用的alachlor。这些结果表明,简单的用肥皂和水清洗是去除皮肤上某些化学物质的适当方法。仅用水清洗的效果不如用肥皂和水清洗。
...The in vivo percutaneous absorption of alachlor in rhesus monkeys was 17.3 +/- 3.3, 15.3 +/- 3.9, and 21.4 +/- 14.2% for 24-hr skin exposure to Lasso formulation diluted 1:20, 1:40, and 1:80, respectively. In vivo, there was no support for increased alachlor skin absorption with water dilution, as previously reported for in vitro absorption. The average in vivo absorption of 18% applied dose over 24 hr (0.75%/h) was similar to the maximum in vitro rate of 0.8%/hr using human skin and human plasma as receptor fluid. Dose accountability in vivo was 80.6-95.2%. (14-14C)Alachlor in Lasso diluted 1:20 with water was placed on rhesus monkeys at concentrations of 23 micrograms/10 microliters/cm2. Skin decontamination at 0 h with soap and water (50% Ivory liquid 1:1 v/v with water) removed 73 +/- 15.8% (n = 4) of the applied dose with the first wash; this increased to a total of 82.3 +/- 14.8% with two additional washes. Decontamination after 1 h removed 87.5 +/- 12.4% with three successive washes. After 3 h decontamination ability decreased, and after 24 h only 51.9 +/- 12.2% could be recovered with three successive washes. Using water only, at 0 h 36.6 +/- 12.3% alachlor was removed with the first wash and the total increased to 56.0 +/- 14.0% with two additional washes. At 24 h the total amount decreased to 28.7 +/- 12.2% for three successive washes. Alachlor as Lasso in field-use rate (11 micrograms/cm2) and undiluted (217 and 300 micrograms/cm2) proportions were left on rhesus monkey skin for 12 h and decontaminated with soap and water (10% Ivory liquid v/v with water). Continual successive washes (6-8 in sequence) recovered 80-90% of the skin-applied alachlor. These results suggest that simple washing with soap and water is appropriate for removing some chemicals from skin. Decontamination with only water was less effective than with soap and water.

制备方法与用途

甲草胺 用途

甲草胺又称拉索、杂草锁、草不绿,是一种酰胺类内吸选择性除草剂。适用于大豆、花生、棉花、玉米、油菜、小麦及蔬菜等作物使用,防除多种一年生禾本科杂草和苋、藜等阔叶杂草,对菟丝子也有一定的防效。

制法

甲草胺的合成方法如下:2,6-二乙基苯胺与甲醛水溶液反应生成物再与氯乙酰氯反应,生成加成物。该加成物在氨作用下与甲醇反应,进行甲酰化,最终制得甲草胺。

毒性

大鼠急性经口LD50为1200mg/kg,家兔急性经皮LD50为5000mg/kg(13300mg/kg);大鼠急性吸入LC50>1.04mg/L。大鼠90d饲喂试验无作用剂量为每天17mg/kg,慢性无作用剂量2.5mg/kg。无致畸、致突变作用,小鼠在15mg/kg和240~260mg/kg剂量下出现支气管肺泡肿瘤和肝、肺肿瘤。鲤鱼LC503.72mg/L。

化学性质

甲草胺为奶油色固体。

用途

甲草胺是一种选择性旱地芽前除草剂,植物幼芽吸收药剂后,抑制蛋白酶的活力,阻碍蛋白质合成,致使杂草死亡。主要用于在出苗前土壤中萌发的杂草,对已出土杂草基本无效。防除大豆、棉花、甜菜、玉米、花生、油菜等旱地作物田间的一年生禾本科杂草,如稗草、牛筋草、秋稷、马唐、狗尾草、蟋蟀草、臂形草等,用量一般为20~30g有效成分/100m²。如在大豆播种后至出苗前使用,用48%乳油30~45mL/100m²,对水均匀喷雾土表。如玉米、蔬菜、花生播种出苗前或移栽前使用,用48%乳油30~38mL/100m²,对水喷雾土表。

用途

甲草胺被杂草的幼苗根部吸收,干扰核酸和蛋白质合成,阻止细胞增大,从而抑制根的伸长,然后导致整个植株死亡。主要用于防除一年生禾本科杂草及部分阔叶杂草,适用于多种作物田间使用。

制备方法

甲草胺可以通过以下两种制备方法获得:

  1. 第一种方法:2,6-二乙基苯胺与甲醛水溶液反应生成物再与氯乙酰氯反应,生成加成物。该加成物在氨作用下与甲醇反应,进行甲酰化,最终制得甲草胺。

  2. 第二种方法

    • 由2,6-二乙基胺与甲醛反应,制得2,6-二乙基-N-亚甲基苯胺。
    • 将298g (1.82mol) 2,6-二乙基-N-亚甲基苯胺缓慢加入到206g (1.82mol) 氯乙酰氯和210g 苯的混合液中,反应生成物加热至约90℃。
    • 冷却至35℃后,加入250mL 干燥甲醇,并回流。滴入190g (3.2mol) 三甲胺,保温10min,冷却至约30℃。
    • 将冷却后的反应混合物用1000mL 水分两次洗涤,因生成物为重油层,采用减压脱溶。最终液温升至95℃后,蒸馏渣溶解在三甲基戊烷中,干冰冷却后析出结晶,得甲草胺,熔点38.5~39.5℃,收率约85%。
