产品描述 | pyridoxal isonicotinoyl hydrazone (PIH) is a cell-permeable and relatively non-toxic iron (Fe3+) chelator that shows high iron chelation efficacy both in vitro and in vivo. |
体外活性 | After a 60-minute reincubation of 59Fe-labeled reticulocytes with tris-hydroxamate deferoxamine (5 mmol/L), 3.5% of cellular 59Fe was released, although Pyridoxal isonicotinoyl hydrazone (PIH) at a 50-fold lower concentration (0.1 mmol/L) released 38.6% of cellular 59Fe [1]. In primary human hepatocytes and the human hepatocellular carcinoma cell line HepG2/C3A, PIH treatment decreases Fech protein levels, but not Fech mRNA levels; and PIH is detected after isoniazid treatment, with levels increasing further when exogenous vitamin B6 analogs are coadministered [2]. |
体内活性 | Intraperitoneal administration of PIH to mice (5 mg/25 gm mouse/day) over 6 days decreased 59Fe levels in the liver, spleen, and kidney but not in the blood. After oral administration, PIH resulted in an eightfold increase in fecal Fe excretion and possibly some urinary excretion of Fe [1]. |

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。
