Histamine

Histamine, an organic nitrogenous compound, is involved in local immune responses regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. It is a potent H1 and H2 receptor agonist.

Biological Activity

Description Histamine, an organic nitrogenous compound, is involved in local immune responses regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. It is a potent H1 and H2 receptor agonist.
In vitro
In vitro Histamine stimulates the proliferation of human articular chondrocytes in culture. Histamine is reported to modify the behaviour of many cell types in vitro, including chondrocytes, fibroblasts, macrophages, epithelial cells, endothelial cells, and T cells. Histamine also modulates the production of many cytokines and the expression of their receptors. Histamine regulates cellular processes through the expression of histamine receptors. Histamine stimulates the production of matrix metalloproteinases (MMPs)-13 and -3 (collagenase 3 and stromelysin-1, respectively) by histidine decarboxylase (HAC) in vitro[1].
Cell Research Cell lines human articular chondrocytes
Concentrations 1-100 μmol/l
Incubation Time 6 days
Method Cells are grown to confluence in 80 cm2 culture flasks in Dulbecco's modified Eagle's medium (DMEM) + 10% fetal calf serum (FCS). At first or second passage, cells are seeded into 96 well culture plates, at densities of approximately 2×103 cells/well. After 24 hours the cells are treated with either DMEM +2% FCS alone (control), or DMEM + 2% FCS plus histamine range 1-100 μmol/l (minimum of eight wells for each treatment). The medium with or without histamine is replenished every 48 hours, and after six days cell growth is estimated.
In Vivo
In vivo Histamine has a recognised role in allergic and inflammatory reactions and is an important modulator of numerous physiological processes, including cell proliferation, angiogenesis, and vasopermeability[1]. Histamine dilates vasculature, increases blood flow, while it induces hyperpermeability in venula. It disrupts endothelial barrier formation of venula indicated by changes in vascular endothelial cadherin (VE-cadherin) localization at endothelial cell junction[3].

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.
