D-Galactose

Synonyms: D-Galactopyranose, D-(+)-Galactose

D-Galactose (D-Galactopyranose, D-(+)-Galactose) is an aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins and is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. It accelerates senescence in invertebrates and mammals and has been used as a model for aging.

Biological Activity

Description D-Galactose (D-Galactopyranose, D-(+)-Galactose) is an aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins and is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. It accelerates senescence in invertebrates and mammals and has been used as a model for aging.
In vitro
In vitro D-Galactose (D-gal) can induce oxidative stress in non-cancer cells and result in cell damage by disturbing glucose metabolism. D-Gal treatment can transcriptionally up-regulate the genes relevant to necroptosis (Bmf, Bnip3) and autophagy (Atg5, TIGAR) but not the genes related to apoptosis (Caspase3, Bax, and p53). D-Gal does not activate Caspase-3, but prompts puncta-like GFP–LC3 distribution, an indicator for activated autophagy[1].
Cell Research Cell lines Mouse neuroblastoma cell line Neuro2a (N2a), human neuroblastoma cell line SH-SY5Y, human prostate cancer cell line PC-3 and mouse fibroblast cell line NIH3T3; Human hepatoma cell line HepG2 and human hepatocyte cell line LO2
Concentrations 0-60 g/L
Incubation Time 24 h
Method

Mouse neuroblastoma cell line Neuro2a (N2a), human neuroblastoma cell line SH-SY5Y, human prostate cancer cell line PC-3 and mouse fibroblast cell line NIH3T3 are cultured in DMEM supplemented with 10% FBS, 100 U/ml penicillin, and 100 mg/ml streptomycin. Human hepatoma cell line HepG2 and human hepatocyte cell line LO2 are cultured in RPMI 1640 with 10% FBS. Cells are maintained at 37℃ with 5% CO2, and treated with D-gal or glucose in the concentrations and the time periods. Morphological assessments are conducted under microscope. Cell viability is evaluated by MTT assay.

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.
