Biological Activity

[Description]:

Diflucortolone valerate is a powerful corticosteroid used topically for the research of various skin diseases[1].

Signaling Pathways >> Others >> Others

Research Areas >> Inflammation/Immunology

[In Vitro]

Diflucortolone valerate is a potent corticosteroid esterified with valeric acid. Diflucortolone valerate helps reduce swelling, itching, and redness[1].

[In Vivo]

DL50 values are virtually non-toxic after single oral administration (mouse greater than 4 g/kg, rat ca. 3.1 g/kg, dog greater than 1 g/kg). Given s.c. (LD50 mouse ca. 180 mg/kg, rat ca. 13 mg/kg) and i.p. (LD50 mouse ca. 450 mg/kg, rat ca. 98 mg/kg) it is highly active and therefore produces also toxic effects[2].
