体外研究

Ko143 (10nM) significantly decreases (2.5-fold) the IC50 of MTX for HEK G2 cells and mouse G2 cells.Ko143 (1-100μM) metabolite does not inhibit the function of ABC Transporters.Reversal of drug resistance in SKF 104864A-selected mouse MEF3.8/T6400 cells and human IGROV1/T8 cells by FTC analogue Ko143.Ko143 is applied at zero,one,or eight times the EC90 concentration of 25nM.Ko143 inhibits BCRP-mediated transport of ZD 4522 in Madin-Darby Canine Kidney (MDCK) 2-BCRP421CC (wild type) cells and MDCK2-BCRP421AA (mutant type) cells.

体内研究

Ko143 (10mg/kg,p.o.) increases the oral availability of SKF 104864A in mice.Ko143 significantly affects the pharmacokinetics of ZD 4522 in rats.

 

推荐实验方法(仅供参考)

细胞实验:

 

cells are plated at 400 or 1000/well in 96-well plates the night before addition of drugs.A concentration series of drug is applied along one plate axis and left for the duration of the assay.Plates are harvested after 4-5 days while untreated wells are still subconfluent.Relative cell proliferation is quantified with CyQuant or Sybr Green I fluorescent nucleic acid stains.Assays with human cell lines are performed in the presence of 0.1μm PSC833 to inhibit confounding P-gp activity.

 

动物实验:

 

Oral toxicity of FTC analogues in mice is tested by mixing 50mg/mL stocks in DMSO 1:1 with Tween 80 (polyoxyethylene sorbitan mono-oleate) and diluting with 5% w/v glucose such that the final volume administered by oral gavage is 10μL/g of body weight.Pairs of mice are administered oral doses of 50mg/kg Ko132,Ko134,Ko143,or vehicle under light methoxyflurane anesthesia.Final tests of 50mg/kg Ko134 or Ko143 are performed on additional pairs of unanesthetized animals to observe any behavioral effects.Further,another pair of mice receive the higher dose of 100mg/kg Ko134.For i.p.toxicity tests,the FTC analogue stocks in DMSO are dispersed in at least 10 volumes of sterile corn oil such that the injected volume is 5μL/g of body weight.After pilot tests at lower doses show no adverse effects,mice (4 per group) are administered vehicle or 10mg/kg i.p.of Ko132,Ko134,or Ko143.The mice are observed continuously during the first hour after administration and then at increasing intervals for 2 weeks,after which they are sacrificed for histological examination of major organs and structures including brain,salivary glands,heart,lungs,liver,adrenal glands,kidneys,urinary tract,spleen,thymus,bone marrow,pancreas,stomach,intestines,cecum,colon,testes,epididymus,skin,head,trunk,and limbs.

请在下列方框中输入相关信息后点击计算,可以得到母液配置方法和体内配方的制备方法:
举例:给药剂量是10 mg/kg,每只动物体重20g,给药体积100 μL, TargetMol | Animal experiments  一共给药动物10只,您使用的配方为5%TargetMol | reagent DMSO 30%PEG300 5%Tween 80 60%Saline/PBS/ddH2O, 那么您的工作液浓度为2mg/mL
母液配置方法: 2 mg 药物溶于 50 μLDMSOTargetMol | reagent  ( 母液浓度为 40 mg/mL ), 如您需要配置的浓度超过该产品的溶解度,请先与我们客服联系。
体内配方的制备方法: 取 50μLDMSOTargetMol | reagent  母液,添加 300 μLPEG300TargetMol | reagent  混匀澄清,再加 50μLTween80, 混匀澄清,再加 600μLSaline/PBS/ddH2OTargetMol | reagent ​ 混匀澄清

以上为“动物实验计算换算器”的使用方法举例,并不是具体某个试剂的配制,请根据您的实验动物和给药方式选择适当的溶解方案。
第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶于水的药物;不同批次药物配方比例不同,请联系普西唐客服为您提供正确的澄清溶液配方)
