| Description | 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. |
| In vitro | 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]. |
| In vivo | 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]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
