Magnesium violacetate B (20–60 μg/ml; 24 h) can dramatically suppress cardiomyocyte apoptosis, decrease intracellular ROS and MDA levels, raise SOD activity in cardiomyocytes, and decrease LDH activity in culture supernatant. Demise [2]. Neural stem cell (NSC) proliferation is enhanced by magnesium violacetate B (1-100 μg/ml) in a dose-dependent manner [3]. It has been observed that in vitro NSC development into neurons can be aided by magnesium lithospermate B (10 μg/ml) [3].

ln Vivo |
By lowering reactive oxygen species, magnesium lithospermate B (2–8 mg/kg; orally, once daily for 16 days) protects the kidneys from oxidative stress in elderly rats [1]. In PD animals, magnesium violacetate B (0.5 μg/g; subcutaneous injection for 6 weeks) can enhance cognition and stimulate neurogenesis [3].

Animal Protocol |
Animal/Disease Models: Young (5 months old) and old (20 months old) specific pathogen-free male SD (SD (Sprague-Dawley)) rats [1]
Doses: 2, 8 mg/kg Route of Administration: po (po (oral gavage)) one time/day, continuous 16-day Experimental Results: diminished nicotinamide adenine dinucleotide phosphate oxidase (Nox4 and p22phox), phospho-p38, nuclear factor-κB p65, cyclooxygenase-2, and inducible nitric oxide synthase major subunits protein expression. demonstrated lower levels of senescence-related proteins such as p16, ADP-ribosylation factor 6, p53 and p21. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (3.37 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), 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 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 (3.37 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.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
