PF-1163A

产品编号 TN7560   CAS 258871-59-9

PF-1163A, a depsipeptide antifungal compound isolated from Penicillium, blocks ergosterol synthesis with an IC50 of 12 ng/ml. This compound specifically inhibits the enzyme ERG25p, a C-4 methyl oxidase in the ergosterol biosynthetic pathway, leading to its antifungal activity. Notably, in Saccharomyces cerevisiae modified to express ERG biosynthesis genes, PF-1163A exhibits an inhibition concentration (MIC value) of 12.5 µg/ml against ERG25p, though strains overexpressing ERG25p show resistance. Additionally, PF-1163A effectively suppresses the growth of Candida albicans (MIC = 8 µg/ml), without affecting other Candida species, Aspergillus fumigatus, or HepG2 cells. Remarkably, it enhances the efficacy of fluconazole against azole-resistant C. albicans strains, showing a significant decrease in MICs (1 and 0.0078 µg/ml alone and in combination, respectively). PF-1163A distinguishes itself from PF-1163B by its more polar nature.

TargetMol Calculator 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5% DMSO+30% PEG300+5% Tween 80+60% 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 50 μL DMSO (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,请先与我们联系。

体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。

第一步:请输入动物实验的基本信息
