产品介绍


Phenolphthalein AI Summary
Phenolphthalein exhibits a diverse range of bioactivities across various biological targets and pathways. It acts as an inhibitor of multiple thymidylate synthase enzymes, including those from Lactobacillus casei (Ki = 4700.0 nM, IF = 0.444), Pneumocystis carinii (IF = 0.608), and humans (IF = 0.182). The compound also shows cytotoxicity against mock-infected MT-4 cells (CC50 = 58000.0 nM) and inhibits the growth of several pathogens such as Staphylococcus aureus (MIC > 58000.0 nM), Streptococcus (MIC = 38000.0 nM; MGC = 58.0 uM), and Cryptococcus neoformans (MIC > 58000.0 nM). Additionally, it has shown effects on the accumulation of radioactivity in COS-7 cells and displays minimal differences in logD between pH 6.5 and 7.4, indicating a partition coefficient of 2.41. In terms of enzyme inhibition, Phenolphthalein demonstrates activity against UGT enzymes, notably UGT1A8 and UGT1A9, and has moderate action against OATP1B1 and OATP1B3 at 10 uM. It also has some effectiveness against SARS-CoV-2, inhibiting virus-induced cytotoxicity in Vero and Caco-2 cells, though with a relatively high IC50 (greater than 20,000 nM). Furthermore, it inhibits the SARS-CoV-2 3CL-Pro protease at 20µM. Despite its multiple activities, the compound shows limited oral bioavailability in humans (F ≤ 20%) and low effectiveness in inhibiting certain targets, including the HDAC6 enzyme and SARS-CoV-2 in specific cell lines. The bioactivity spectrum of Phenolphthalein indicates its potential utility as a multifaceted inhibitor with applications in antibacterial, antiviral, and enzyme inhibition therapies, though its clinical utility may be constrained by its moderate potency and bioavailability..

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。
