Metabolism / Metabolites
In liver extracts from rats treated with leucomalachite green (LMG), primarily protonated LMG, protonated demethylated derivatives and the molecular ions of malachite green N-oxide and demethylated N-oxide derivatives were seen. A small, but measurable, amount of malachite green was also found. A dose-related increase in LMG and metabolites was observed in both rat and mouse liver extracts. ... The reduction of malachite green (MG) to leucomalachite green (LMG) by intestinal bacteria from humans, rats, mice and rhesus monkeys and 14 pure cultures of anaerobic bacteria representative of those found in the human gastrointestinal tract. The bacterial cultures were incubated with 300 ug of MG in 5 mL of brain-heart infusion broth for 24-48 hr under anaerobic conditions. Virtually all of the MG was converted to its LMG derivative by the intestinal microflora. The pure bacterial cultures converted 7.3-99.3% of the MG to LMG. These results indicate the importance of the gastrointestinal tract microflora in the conversion of MG to LMG. Intestinal microfloras from human, rat, mouse, and monkey fecal samples and 14 pure cultures of anaerobic bacteria representative of those found in the human gastrointestinal tract metabolized the triphenylmethane dye malachite green to leucomalachite green. The reduction of malachite green to the leuco derivative suggests that intestinal microflora could play an important role in the metabolic activation of the triphenylmethane dye to a potential carcinogen. Malachite green (MG) is still illegally used as a fungicide in aquaculture. In fish it is absorbed and metabolised to its major reduced metabolite, leucomalachite green (LMG). This latter represents the main residue found in fish tissues and may persist for several months. Biological Half-Life The half-life of LMG residence in trout muscle may be as long as 40 days. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.56 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (7.56 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
