Description
Dexamethasone Acetate is a glucocorticoid with anti-inflammatory properties. One possible mode of action of the anti-inflammatory properties has been documented by Dexamethasone Acetate inhibitiing upregulation of ICAM-1 (intercellular adhesion molecule-1) in cultured human mast cells. The compound also displays anti mitotic activity against chemically transformed mouse fibroblasts by halting mitosis from entering the S-phase. Dexamethasone Acetate has also been determined to markedly decrease the number of activated macrophages. In addition, Dexamethasone Acetate has been observed to significantly decrease mRNA levels of TPH2 (tryptophan hydroxylase-2) in the raphe nuclei of C57/Bl6 mice.as a foam under the tradename Verdeso Foam. It is a group VI corticosteroid under US classification, the second least potent group.
