Absorption, Distribution and Excretion
In rats, following oral administration, 92% was excreted in the urine and 5% in the feces within 24 hr. Residue levels in blood, liver, kidney, muscle, and fat tissues were <0.01 ppm after 48 hr. Metabolism / Metabolites In a rat metabolism study, almost 100% of the administered radiolabeled test material /imazethapyr/ was recovered in the excreta within 96 hours (89-95% in the urine and 6-11% in the feces). Greater than 95% of the oral dose was excreted in the first 31 hours. The major residue in both urine and feces was the parent compound. Approximately 2% of the oral dose was metabolized and excreted as CL 288511 (1-hydroxy ethyl derivative of imazethapyr). A high percentage of the administered material was excreted in the urine as the unmodified parent compound (> 97%) and a very small amount as CL 288511. In the high dose group, the unmodified parent compound was the major fecal component in both sexes, particularly at 12 hours or less. CL 288511 was the major metabolite. One unknown metabolite was also found in significant quantities. In the low dose group, six components were found in the feces: parent compound, CL 288511, the unknown previously mentioned and three minor unknowns. Rapidly metabolized in non-susceptible plants (50% loss in soyabeans in 1.6 days). |

其他信息 |
Imazethapyr is an aromatic carboxylic acid and a member of pyridines.
Mechanism of Action Absorbed by plant roots and foliage, being translocated to meristematic regions where it inhibits the biosynthesis of valine, leucine and isoleucine preventing cell division. Imazapyr (IMZR), Imazapic (IMZC), Imazethapyr (IMZT), Imazamox (IMZX) and Imazaquin (IMZQ) ... are classified as imidazolinone (IMI) herbicides and their mode of action is to inhibit acetohydroxyacid synthase (AHAS), an enzyme involved in the biosynthesis of the amino acids leucine, isoleucine and valine. ... |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
