Biological Activity

Description Isoniazid is a prodrug that blocks the action of fatty acid synthase by interacting with KatG , used for the prevention and treatment of tuberculosis.
In vitro
In vitro Isoniazid is a prodrug that requires activation by the mycobacterial catalase-peroxidase enzyme (KatG) to an active form that then exerts a lethal effect on an intracellular target or targets. [1] Isoniazid upregulates the expression of an operon containing five FAS II components, including kasA and acpM. Isoniazid results in the accumulation of ACP-bound lipid precursors to mycolic acids that are 26 carbons long and fully saturated. [2] Isoniazid enters the mycobacterial cell by passive diffusion. Isoniazid itself is not toxic to the bacterial cell, but acts as a prodrug and is activated by the mycobacterial enzyme KatG, a multifunctional catalase-peroxidase that has other activities, including peroxynitritase and NADH oxidase. Isoniazid inhibits cell wall lipid synthesis, coupled with the findings that inhibitory INH adducts of NAD+/NADP+ are formed from the isonicotinoyl radical, leading the field away from this area. [3] Isoniazid induces a concentration-dependent (0-40 mM) cytotoxic effect in day-1 treated HepG2 cells and not significantly affected by decreases in intracellular GSH concentrations. [4]
In Vivo
In vivo Isoniazid increases CYP2E1 protein, and the 6-hydroxychlorzoxazone formation rate is increased by 2.7 and 2.2-fold in liver and kidney, respectively. Isoniazid decreases liver and kidney 20-HETE content to 34% and 15.6% of control, respectively, without significantly altering tissue 19-HETE concentration. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
