Biological Activity

Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist that induces the production of phospholipase A2 inhibitory protein. Dexamethasone inhibits production of exosomes containing inflammatory microRNA-155 in lipopolysaccharide-induced macrophage inflammatory responses. Dexamethasone also inhibits induction of nitric oxide synthase with IC50 of 5 nM. Dexamethasone reduces levels of activated NF-κB in immature dendritic cells (DCs) and inhibits differentiation into mature DCs. Dexamethasone induces differentiation of human mesenchymal stem cells (MSCs). Dexamethasone also induces autophagy in acute lymphoblastic leukemia (ALL) cell lines. Dexamethasone is used to treat many inflammatory and autoimmune conditions, such as rheumatoid arthritis and bronchospasm.It can be used to construct models of allergic conjunctivitis.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Heparin sodium salt (MW 15kDa)

Heparin sodium salt (MW 15kDa) is a heparin polymer with a molecular weight of 15kDa.Heparin sodium salt is an anticoagulant that reversibly binds to antithrombin III (ATIII), thereby accelerating the rate of inactivation of Thrombin factor IIa and factor Xa by ATIII. Heparin sodium salt is used for blood collection and plasma preparation in experimental animals and for the construction of parenteral nutrition models in mice.
