Application

Roflumilast has been used to evaluate its effect on acute lung inflammation and chronic lung changes in models of cigarette exposure in mice. It is also used to investigate its therapeutic potential to ameliorate primary blast-induced deficits in long-term potentiation (LTP).

Biochem/physiol Actions

Roflumilast is a highly potent, orally active, and selective phosphodiesterase 4 (PDE4) inhibitor with an IC50 of 0.8 nM. Roflumilast has anti-inflammatory properties and is used clinically to treat COPD.

Discover Bioactive Small Molecules for Cyclic Nucleotides

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
