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.

Mechanism of Action

Targets/IC₅₀/Ki	Glucocorticoid receptor
In vitro	Prednisone blocks Peripheral blood lymphocytes (PBL) growth in the G1 phase of cell cycle and inhibits both IL-2 receptor (IL-2R) expression and IL-2 secretion in activated human peripheral blood T lymphocytes. This compound increases apoptosis in PHA-activated human PBL, and the apoptotic effect of this chemical is stronger on CD8(+) than on CD4(+) T lymphocytes.
In vivo	Prednisone-treated rats show a significant delay of 20% in learning and memory retention in rats as compared with controls. This compound results in reduced weight gain, unchanged alter uterine weight, lowered serum magnesium (Mg), unchange serum calcium (Ca), phosphate (P), 25-hydroxyvitamin D (25OHD), or 1,25-dihydroxyvitamin D [1,25(OH)2D], striking increased in calcified cartilage, reduced cross-sectional area and cortical area, unchange medullary area of the tibial diaphysis, lowered periosteal and endocortical bone formation and apposition rates, increased mean cancellous bone area and cancellous bone perimeter of the tibial metaphysis in both sham-operated and ovariectomized rats. This chemical-treated rabbit shows a 30% reduction in percent stenosis, a 35% decrease in neointimal area, and a 66% decrement in neointimal thickness. This treatment significantly reduces the level of TGF-beta1 and HYP in diaphragm from mdx mice to values similar to control mice, but results in a higher level of the HP cross-link compared with untreated mdx mice.
