| In vitro | As a PDEIV inhibitor, Cilomilast inhibited TNFalpha release at concentrations >300 nM, but shows no inhibition to IL-6 release at any of the concentration in COPD lung macrophages. Cilomilast produces a concentration-dependent increase in cAMP content in U937 cells. Cilomilast produces a concentration-dependent increase in cAMP content in U937 cells. Cilomilast decreases the expression of IL-17 and IL-23 in the draining lymph nodes. Cilomilast reduces TLR4 expression, IL-8 release and neutrophil chemotactic activity as well as it increased IP-10 release and lymphocyte chemotactic activity. | |||||
| IN vivo | Cilomilast inhibits human TNFalpha production with oral ED50 of 4.9 mg/kg. In contrast to their equipotent activity against TNFalpha production, Cilomilast (ED50 = 2.3 mg/kg, p.o.) is 10-fold less potent than R-rolipram (ED50 = 0.23 mg/kg, p.o.) in reversing reserpine-induced hypothermia, a model of antidepressant activity. | |||||
