产品介绍


Xanthine AI Summary
Xanthine exhibits a range of bioactivities across various assays and biological systems. It demonstrates relaxant activity on guinea pig tracheal ring chains with an EC50 value greater than 100,000 nM, and shows a positive chronotropic effect on guinea pig right atrium with an EC15 value greater than 100 μM, coupled with low affinity towards the adenosine A1 receptor (Ki > 200,000 nM). The compound also inhibits cyclic AMP phosphodiesterase activity in guinea pig tracheal muscle (Ki > 200,000 nM) and has a broncho selectivity ratio of 1.0. In cellular assays, it inhibits adenosine-stimulated accumulation of cyclic AMP at the Adenosine A2 receptor in rat VA13 fibroblasts (Ki = 130,000 nM) and demonstrates inhibitory activity against Escherichia coli CTP synthetase. In enzyme inhibition studies, Xanthine inhibits Glucose-6-phosphate dehydrogenase (Ki = 1,960 nM), Plasmodium falciparum HGXPRT enzyme (Km = 189,000 nM at pH 7.4, Km = 420,000 nM at pH 8.5), and bovine xanthine oxidase (Km = 21,400 nM, Vmax = 2.768 μM/min), as well as human Acetylcholinesterase (IC50 = 9,000 nM). Additionally, Xanthine potentiates calcium release induced by cADRP in sea urchin egg homogenates at 2 mM concentration, showing a potentiation of 41.0%. It has an insulinotropic effect on rat pancreatic beta-cells, increasing insulin release to 7.72 ng/islet/h after PBS rinsing. The compound activates thyroid hormone receptor beta signaling in a qHTS assay with a potency of 50.1 nM. Xanthine exhibits substrate activity with ADH101 and ADH105 enzymes using NADH as a cofactor, with specific enzyme activities of 319.0 nmol/min/mg for ADH101, and 9.28 nmol/min/mg and 15.9 nmol/min/mg for ADH105 with and without hexane presence, respectively. Furthermore, it has a pKa value of 7.7, indicative of its dissociation properties under physiological conditions..

生物活性
产品描述
Xanthine (Isoxanthine) is a product on the pathway of purine degradation. Xanthine is subsequently converted to uric acid by the action of the Xanthine oxidase enzyme. Xanthine is found in most body tissues and fluids in various organisms. Biologically Xanthine is produced from guanine by cypin (guanine deaminase). Furthermore, Xanthines act as antagonists for adenosine receptors, with selectivity depending on whether there are substitution of alkyl groups.

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法:
比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL, 一共给药动物10只,您使用的配方为 10% DMSO + 40% PEG300 + 5% Tween 80 + 45% Saline / PBS / ddH2O, 那么您的工作液浓度为2 mg/mL
母液配置方法:2 mg 药物溶于 100 μL DMSO ( 母液浓度为 20 mg/mL ), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:100 μL DMSO 母液, 添加 400 μL PEG300 混匀澄清, 再加 50 μL Tween 80, 混匀澄清, 再加 450 μL Saline / PBS / ddH2O 混匀澄清
以上为“体内实验配液计算器”的使用方法举例,并不是具体某个化合物的推荐配制方式,请根据您的实验动物和给药方式选择适当的溶解方案。
方案所需的各类助溶剂如: DMSOPEG300PEG400Tween 80SBE-β-CD玉米油等, 均可在TargetMol网站点击购买。
